The present application is based on, and claims priority from JP Application Serial Number 2018-166530, filed Sep. 6, 2018, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present disclosure relates to a terminal apparatus, a communication system, and a non-transitory computer-readable storage medium storing a program.
In JP-A-2011-188518, a technology is disclosed in which a user selects an SSID of a connection target from among service set identifiers (SSIDs) that are displayed on a display unit of a multifunction machine that is capable of making a connection to a wireless local area network (LAN) by operating an operation unit, such that the multifunction machine makes a wireless connection to an access point (AP) to be connected.
It is conceivable to perform a wireless connection setting of electronic equipment such as a printer using a terminal apparatus such as a smartphone. For example, in a case where a display unit of the electronic equipment is small, or in a case where the electronic equipment does not have the display unit at first, it is effective to use the terminal apparatus for a connection setting.
However, when the connection setting of the electronic equipment is performed using the terminal apparatus, the user is not always in front of the display unit of the electronic equipment. Thus, even though it is displayed that wireless connection is successful on the display unit of the electronic equipment, there is a concern that the user may not notice it. Further, it is not preferable to force the user to move to a position where the display unit of the electronic equipment is visible in order to make the user to surely recognize the result of the wireless connection, from the viewpoint of convenience.
According to an aspect of the present disclosure, there is provided a terminal apparatus including: a communication unit that performs communication with electronic equipment; and a processing unit that performs control of the communication unit, in which the communication unit transmits an SSID corresponding to an access point that is a connection target in a first wireless communication scheme of the electronic equipment to the electronic equipment in compliance with a second wireless communication scheme, and receives an identifier of the electronic equipment from the electronic equipment in compliance with the second wireless communication scheme, and when the communication unit receives the identifier of the electronic equipment transmitted by the electronic equipment after the transmission of the SSID in compliance with the second wireless communication scheme in compliance with the first wireless communication scheme and it is determined that the identifier received in compliance with the first wireless communication scheme matches the identifier received in compliance with the second wireless communication scheme, the processing unit performs notification processing of notifying that a connection between the electronic equipment and the access point is successful.
Hereinafter, the present embodiment will be described. It is noted that the present embodiment which will be described below does not improperly limit the subject matter of the present disclosure that is claimed in claims. Furthermore, all configurations that will be described in the present embodiment are not necessarily configurational requirements for the present disclosure.

The terminal apparatus 100 of the present embodiment includes a memory storing information, and a processor which operates based on the information stored in the memory. The information is, for example, programs, various kinds of data, and the like. The processor includes a hardware. As the processor, it is possible to use various processors such as a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processor (DSP), and the like. The memory may be a semiconductor memory, such as a static random access memory (SRAM) or a dynamic random access memory (DRAM), a register, a magnetic storage device such as a hard disk drive (HDD), and an optical storage device such as an optical disk device. For example, a memory stores readable instructions by a computer, the instruction is executed by a processor, and the function of each section of the terminal apparatus 100 is implemented as a process. The instruction here may be an instruction of an instruction set configuring the program, and may be a command for instructing an operation to the hardware circuit of the processor.
The communication unit 120 performs communication with the access point and the electronic equipment via an antenna (not shown).

The first wireless communication scheme is a wireless LAN in a narrow sense, and more specifically, Wi-Fi. The second wireless communication scheme is a wireless communication scheme that is different from the first wireless communication scheme. The second wireless communication scheme is, for example, a wireless communication scheme conforming to the standard of Bluetooth (registered trademark), and is a wireless communication scheme conforming to the Bluetooth Low Energy standards in a narrow sense. Bluetooth Low Energy will be described below as BLE. However, other communication methods may be used as the first wireless communication scheme and the second wireless communication scheme.
In this manner, by using a different wireless communication scheme, it becomes easy to connect the electronic equipment 200 to an appropriate access point 300 using the terminal apparatus 100.
For example, with the use of BLE as the second wireless communication scheme, the connection between the terminal apparatus 100 and the electronic equipment 200 can be established more easily compared to the case of using Wi-Fi, it is possible to smoothly perform transmission and reception of information for connecting the electronic equipment 200 to the access point.
Furthermore, in addition to the configuration illustrated in

And the storage unit 160 may be a magnetic storage device such as a hard disk device and an optical storage device such as an optical disk device and the like.
The electronic equipment 200 is, for example, a printer. Alternatively, the electronic equipment 200 may be a scanner, a facsimile machine, or a copy machine. The electronic equipment 200 may be a multifunction peripheral (MFP) that has a plurality of functions, and a multifunction peripheral that has a printing function is also an example of the printer.

The printing engine, for example, includes a transportation mechanism, an ink jet type discharge head, and a driving mechanism for a carriage including the discharge head, and the like. The printing engine discharges ink from the discharge head onto the printing medium that is transmitted by the transportation mechanism, and thus prints an image on the printing medium. As the printing medium, various media can be used such as a paper sheet and a piece of cloth. It is noted that a specific configuration of the printing engine is not limited to that described here as an example and may be one in which printing that uses toner is performed using an electrophotographic method.

The processing unit 210 or the communication unit 220, for example, operates with the storage unit 260 as a working area. The storage unit 260 may be a semiconductor memory, a register, a magnetic memory device, and an optical storage device.
The present embodiment will be described below. First, the outline of processing will be described and then the specific processing will be described with reference to
It is considered that setting relating to a wireless connection to the electronic equipment 200 is performed using the terminal apparatus 100. For example, in a case where the display unit 230 of the electronic equipment 200 is small-sized, or in a case where the electronic equipment 200 does not have the display unit 230, the use of the terminal apparatus 100 is effective for the connection setting. Furthermore, even when the electronic equipment 200 has a display panel or the like, it is possible to easily perform a setting operation by using the terminal apparatus 100 familiar to the user.
As a connection setting method of the electronic equipment 200 using the terminal apparatus 100, for example, a method is considered in which the electronic equipment 200 performs SSID scanning and thus creates an SSID list and in which the SSID list is displayed on the display unit 130 of the terminal apparatus 100. The user selects an SSID from the displayed list and inputs a password corresponding to the SSID. The terminal apparatus 100 transmits the SSID and the password to the electronic equipment 200 and thus performs a wireless connection to the electronic equipment 200.
If it is intended to set the electronic equipment 200 to be in a state of being available for Wi-Fi communication, the selection of the SSID by the user is easy. Since the access point that is a connection target is optional when a password is already known, any SSID that is included in the SSID list may be selected.
However, in some cases, the transmission and reception of the information are performed between the terminal apparatus 100 and the electronic equipment 200. For example, in a case where the electronic equipment 200 is a printing apparatus, printing data is created in the terminal apparatus 100. Thereafter, the printing data is transmitted to the electronic equipment 200 through wireless communication, and printing is performed in the electronic equipment 200. Because BLE is lower in communication speed than Wi-Fi, in a case where a certain amount of data, such as the printing data, is transferred, it is possible that user convenience is improved by using Wi-Fi.
On this occasion, it is desirable that the terminal apparatus 100 and the electronic equipment 200 makes a connection to the same access point. When this is done, the terminal apparatus 100 and the electronic equipment 200 include the network segment. Because of this, it is possible that data is transmitted and received reliably and securely between the terminal apparatus 100 and the electronic equipment 200.
However, when performing connection setting of the electronic equipment 200 using the terminal apparatus 100, it is necessary to consider a method to make the user confirm the success or failure of the connection. As in the related art, when the user operates the operation unit 240 of the electronic equipment 200 such as the printer panel performs the connection setting of the electronic equipment 200, the user is considered to be in front of the printer panel serving as the display unit 230. Therefore by displaying the fact that the wireless connection is successful on the printer panel, the user can easily grasp that the wireless connection is successful.
On the other hand, when wirelessly connecting the electronic equipment 200 to the access point 300 using the terminal apparatus 100 such as a smartphone, the user is not always in front of the printer panel. Therefore, even when the fact that the wireless connection is successful is displayed on the printer panel, there is a concern that the user may not notice it. Further, it is inconvenient and undesirable for the user to force the user to move to the position where the printer panel is visible in order to recognize the results of the wireless connection.
Therefore the terminal apparatus 100 of the present embodiment performs notification processing of notifying that the connection between the access point 300 and the electronic equipment 200 is successful. The terminal apparatus 100 according to the present embodiment, as shown in
For example, the communication unit 120 receives the SSID list obtained by the scanning processing by the electronic equipment 200 using the first wireless communication scheme, from the electronic equipment 200 in compliance with the second wireless communication scheme. The communication unit 120 transmits an SSID selected from the SSID list by the user to the electronic equipment 200 in compliance with the second wireless communication scheme as the SSID corresponding to the access point 300 which is a connection target of the electronic equipment 200. The communication unit 120 transmits the password corresponding to the SSID to the electronic equipment 200 in compliance with the second wireless communication scheme.
In this way, it becomes possible to urge the user to select an appropriate SSID using the SSID list. For example, the processing unit 110 executes the processing of S205 of
The terminal apparatus 100 of the present embodiment, by performing communication with the electronic equipment 200 in compliance with the first wireless communication scheme, determines whether the connection between the electronic equipment 200 and the access point 300 has succeeded. In the present embodiment, it is assumed that the connection in compliance with the first wireless communication scheme between the terminal apparatus 100 and the access point 300 is established. That is, when the connection between the electronic equipment 200 and the access point 300 is successful, a communication path in compliance with the first wireless communication scheme exists between the terminal apparatus 100 and the electronic equipment 200, and the communication path does not exist when the connection fails. Thus, by attempting to perform communication conforming to Wi-Fi standards, it is possible to appropriately determine whether the wireless connection has succeeded or failed.
For example, the communication unit 120 receives the identifier of the electronic equipment 200 from the electronic equipment 200 in compliance with the second wireless communication scheme. The processing unit 110 performs notification processing of notifying that the connection between the electronic equipment 200 and the access point 300 has succeeded when the following conditions are met after the transmission of the SSID in compliance with the second wireless communication scheme. Specifically, the processing unit 110 performs the notification processing when the communication unit 120 receives the identifier of the electronic equipment 200 in compliance with the first wireless communication scheme which is transmitted by the electronic equipment 200 and it is determined that the identifier received in compliance with the first wireless communication scheme matches the identifier received in compliance with the second wireless communication scheme.
Thus, by performing the matching process of matching the identifier acquired through BLE in advance and the identifier acquired through Wi-Fi, it becomes possible to determine whether the counterpart of the communication is the electronic equipment 200 which is the setting target, in addition to determining whether the communication through Wi-Fi is performed. The identifier here is, for example, the MAC address of the electronic equipment 200. However, the identifier may be any information capable of identifying the electronic equipment 200, a manufacturing number of the device, other information such as a serial number may be used. Examples using the identifier will be described later with reference to
Alternatively the communication unit 120 may transmit the IP address of the terminal apparatus 100 to the electronic equipment 200 in compliance with the second wireless communication scheme. Terminal apparatus 100 is assumed to be already connected to the access point 300, the IP address of the terminal apparatus 100 is also known in the stage before the completion of connection between the electronic equipment 200 and the access point 300. The processing unit 110 performs notification processing of notifying that the connection between the electronic equipment 200 and the access point 300 is successful when the communication unit 120 receives a notification from the electronic equipment 200 in compliance with the first wireless communication scheme in a given time. The given time here is, for example, a time set based on the transmission timing of the IP address or transmission timing of the SSID, and is, for example, a given length of time starting from any transmission timing.
By transmitting the IP address of the terminal apparatus 100 to the electronic equipment 200, it is possible to transmit the data designating the terminal apparatus 100 from the electronic equipment 200 side. The terminal apparatus 100 can determine that Wi-Fi communication with the electronic equipment 200 is performed by receiving the data addressed to its own IP address. Since the processing unit 110 uses the information transmission to the electronic equipment 200 as a trigger to set the given time which is a standby period, when the notification is received within the time, it can be determined that the notification is likely to be transmitted from the electronic equipment 200. Examples using the IP address will be described later with reference to
Further, there is no limitation to using the method of using the identifier, and the method of notifying the IP address in advance, in combination. Specifically, the processing unit 110 receives the data addressed to its own IP address within a given time, and, if it is determined that the identifier through BLE and the identifier through Wi-Fi match, performs notification processing. For an example of using the identifier and IP address in combination, it will be described below with reference to
First, based on the determination using the identifier, a method of performing notification processing will be described. Specifically, a polling method of periodically requesting acquisition of an identifier from the terminal apparatus 100, and a wait method of waiting for transmission of the identifier from the electronic equipment 200 will be described. In the following, an example will be described in which the identifier of the electronic equipment 200 is a MAC address.
The processing unit 210 controls the first communication unit 221, thus performs reception of a beacon signal, and, based on a result of the reception, creates an SSID list (S102). The beacon signal here is a beacon signal in compliance with the Wi-Fi standards and includes an SSID. The beacon signal in compliance with the Wi-Fi standards will be expressed below as a Wi-Fi beacon. Wi-Fi beacon may include other information such as media access control address (MAC address) of the access point which is a transmission source device, channel information, and the transmission interval of the beacon.
The processing unit 210 stores the created SSID list in the storage unit 260. Specifically, the processing unit 210 acquires the SSID that is included in the beacon signal received by the first communication unit 221, and writes the acquired SSID on the SSID list. At this time, in a case where the acquired SSID is already included in the SSID list, the same SSID is not redundantly written in the SSID list.
Next, the processing unit 210 controls the second communication unit 222 and thus transmits an advertising packet, as a beacon signal in compliance with the BLE standards (S103).
When receiving the advertising packet using the second communication unit 122, the processing unit 110 of the terminal apparatus 100 displays a screen for “notification that inquires whether to make a wireless LAN connection to electronic equipment” on the display unit 130. When the user receives an operation of “approving the wireless LAN connection to the electronic equipment” using the operation unit 140, the processing unit 110 selects the electronic equipment 200 as a counterpart to establish an LBE connection (S104).
It is noted that, in a case where multiple pieces of electronic equipment that transmit the advertising packet are present, the processing unit 110 may display a screen for a list of pieces of electronic equipment on the display unit 130. At this point, the screen that is displayed is a screen on which electronic equipment, for example, are displayed in order of increasing a distance away from the terminal apparatus 100. Because distance estimation that uses the advertising packet is well known, a detailed description thereof is omitted.
Next, the processing unit 110 controls the second communication unit 122 and thus makes a BLE connection to the electronic equipment 200 (S105). It is noted that, although not illustrated in
By performing the processing described above, it is possible that the information transmission and reception that use the BLE connection are possible between the terminal apparatus 100 and the electronic equipment 200. Consequently, subsequent to S105, a sequence for connecting the electronic equipment 200 to the access point 300 is started.
Next, the processing unit 210 of the electronic equipment 200 determines whether the first SSID is included in the SSID list acquired in S102. When it is determined that the first SSID is included in the SSID list, the processing unit 210 transmits a notification that acknowledgment of the SSID succeeds, to the terminal apparatus 100 through the BLE connection (S202). On the other hand, when it is determined that the first SSID is not included in the SSID list, the processing unit 210 transmits a notification that the acknowledgment of the SSID fails, to the terminal apparatus 100 through the BLE connection (S202).
The processing unit 110 of the terminal apparatus 100 checks notification of a result of the acknowledgment of the SSID received from the electronic equipment 200 through the BLE connection (S203). As a result of the acknowledgment of the notification, the processing branches to S204 or S205.
In a case where the notification of the success as a result of the acknowledgment of the SSID is received, the first SSID that is used by the terminal apparatus 100 for connection is equivalent to a case where it is also possible that the electronic equipment 200 conducts a search. In this case, processing in S204 is performed. Specifically, the processing unit 110 of the terminal apparatus 100 displays a screen for receiving an instruction to wirelessly connect the electronic equipment 200 to the access point 300 to which the first communication unit 121 is being connected, on the display unit 130. Specifically, the processing unit 110 displays a screen for checking whether the first SSID is selected as a connection target to the electronic equipment 200, on the display unit 130 (S2041).
When an operation of selecting the first SSID is received by the user, the processing unit 110 displays a password input screen on the display unit 130 and a password of the SSID selected from the password input screen is input to the processing unit 110 (S206). In a case where processing in S204 is performed, the password that is input in S206 is a password that corresponds to the first SSID.
The processing unit 110 transmits the first SSID and the password, which is input in S206, to the electronic equipment 200 through the BLE connection (S207). As will be described later with reference to S303 in
It is noted that when the first SSID is present in the SSID list of the electronic equipment 200, the terminal apparatus 100 does not make a request to the electronic equipment 200 for the SSID list. This serves the object of shortening at least the time the user waits, because it takes time to transmit the SSID list at a communication speed in compliance with the wireless communication scheme in compliance with the BLE standards. However, a modification implementation may be employed in which the electronic equipment 200 transmits the SSID list to the terminal apparatus 100 through BLE communication and in which it is determined on the terminal apparatus 100 side whether the first SSID is included in the SSID list.
On the other hand, in a case where the notification of the failure as a result of the acknowledgment of the SSID is received, the first SSID that is used by the terminal apparatus 100 for connection is equivalent to a case where the electronic equipment 200 is not capable of conducting a search. In this case, processing in S205 is performed. Specifically, the processing unit 110 of the terminal apparatus 100 makes a request to the electronic equipment 200 for the SSID list through the BLE connection (S2051). According to the request for the SSID list from the terminal apparatus 100, the processing unit 210 of the electronic equipment 200 transmits the SSID list, which is stored in the storage unit 260, to the terminal apparatus 100 through the BLE connection using the second communication unit 222 (S2052). The processing unit 110 of the terminal apparatus 100 displays a screen for urging the user to select one from among SSIDs that are included in the SSID list received from the electronic equipment 200 through the BLE connection, on the display unit 130, and the user applies an operation of selecting the SSID to the processing unit 110 (S2053).
Incidentally, there are cases where one access point 300 has a plurality of SSIDs. For example, if the access point 300 is capable of performing communication by the first frequency band and the second frequency band, the access point 300 includes the first wireless communication device that performs communication using the first frequency band, and a second wireless communication device that performs communication using the second frequency band. Then, different SSIDs are assigned to the first wireless communication device and the second wireless communication device respectively. More specifically, the first frequency band is a 5 GHz band, and the second frequency band is a 2.4 GHz band. That is, the first wireless communication device is a device that performs communication which corresponds to standards such as IEEE802.11a, IEEE802.11n, and IEEE802.11ac, and the second wireless communication device is a device that performs communication which corresponds to standards such as IEEE802.11b, IEEE802.11g, and IEEE802.11n. Also, when the access point 300 supports a plurality of communication standards in the first wireless communication scheme, it is assumed that in accordance with the communication standard, a plurality of different SSIDs are included and, differences in communication standards are not limited to the difference of the communication frequency bands.
However, the terminal apparatus 100 makes a connection to the first wireless communication device and the electronic equipment 200 makes a connection to the second wireless communication device, the terminal apparatus 100 and the electronic equipment 200 are also connected to the same access point 300. That is, even when the first SSID does not exist in the SSID list, there remains room where the terminal apparatus 100 and the electronic equipment 200 can be connected to the same access point 300. Therefore, in the process of S2053, the processing unit 110 performs processing that displays an SSID which has a high probability of corresponding to an access point that is the same as the access point 300 to which terminal apparatus 100 is being connected, in a manner that is emphasized for visibility or in a manner that takes precedence, and thus assists the user in the selection.
When any SSID is selected from the SSID list, the processing unit 110 displays the password input screen on the display unit 130, and a password of the SSID selected from the password input screen is input to the processing unit 110 (S206). In a case where the processing in S205 is performed, the password that is input in S206 is a password that corresponds to the SSID selected from the SSID list. The processing unit 110 transmits the SSID selected in S2053 and the password that is input in S206, to the electronic equipment 200 through the BLE connection (S207).
By the above processing, since the electronic equipment 200 acquires the SSID and the password, it becomes possible to attempt to connect conforming to Wi-Fi standards to the access point 300 by the first communication unit 221. However, as mentioned above, only by the above processing, the terminal apparatus 100 cannot grasp whether the connection between the electronic equipment 200 and the access point 300 was successful.
The processing unit 110 of the terminal apparatus 100 performs an acquisition request for the MAC address of the electronic equipment 200 through the BLE connection by the second communication unit 122 (S301). The processing unit 110 of the electronic equipment 200 transmits the MAC address of the electronic equipment 200 to the terminal apparatus 100 through the BLE connection by the second communication unit 222, as a response to the acquisition request (S302). That is, the communication unit 120 of the terminal apparatus 100 receives the identifier of the electronic equipment 200 from the electronic equipment 200 in compliance with the second wireless communication scheme.
Also, the electronic equipment 200 attempts a Wi-Fi connection to the access point 300 through the first communication unit 221 using the acquired SSID and password in S207. When the SSID and the password are appropriate, the Wi-Fi connection between the electronic equipment 200 and the access point 300 is established (S303).
The transmission and reception of the MAC address through the BLE connection shown in S301 and S302, and the establishment of the Wi-Fi connection shown in S303 can be performed in parallel regardless of the execution order. For example, the terminal apparatus 100 transmits the SSID in S207, and then transmits an acquisition request for the MAC address in S301. The electronic equipment 200 receives the SSID in S207, and then starts the Wi-Fi connection to the access point 300 and returns a response for S302 at the timing of receiving the acquisition request for the MAC address. Since it takes tens of seconds to several tens of seconds from the acquisition of the SSID and the password to the completion of the Wi-Fi connection, the processes in S301 and S302 are considered to be finished before S303, but the process in S303 may be finished first. Also, the transmission and reception of the MAC address through the BLE connection shown in S301 and S302 may be performed before the processing of S207.
The communication unit 120 of the terminal apparatus 100 broadcasts the acquisition request for an identifier to the network, after the transmission of the SSID by the second wireless communication scheme, in compliance with the first wireless communication scheme. Specifically, the processing unit 110 broadcasts the acquisition request for MAC address through the Wi-Fi connection by the first communication unit 121 (S304). As shown in
The processing unit 210 of the electronic equipment 200 can recognize that the packet is for the acquisition request of the MAC address, by referring to the contents of the broadcast packet from the terminal apparatus 100. Thus the processing unit 210 returns its own MAC address to the terminal apparatus 100 through the access point 300 by the already established Wi-Fi connection in S303 (S305).
The communication unit 120 of the terminal apparatus 100 receives the identifier of the electronic equipment 200 in compliance with the first wireless communication scheme as a response to the broadcast transmission request. The processing unit 110 of the terminal apparatus 100 determines whether the MAC address received in S302 matches the MAC address received in S305, and performs notification processing when the MAC addresses match (S306). The case where the two MAC addresses match corresponds to a case where the night communication is performed with the electronic equipment 200 which is the target of connection setting, in compliance with Wi-Fi standards through the access point 300. Therefore, the processing unit 110 determines that the connection between the electronic equipment 200 and the access point 300 is successful, and executes notification processing of notifying the user of that effect (S306). The notification processing here is, for example, a process of displaying text, an icon, and an image indicating a successful connection on the display unit 130. However, the notification processing is not limited to this, and may be an output of sound or the like by a speaker, or may be light emission of a light emitting unit such as a light emitting diode (LED).
The broadcast in S304 is started with, for example, the transmission of the SSID in S207 as a trigger. Alternatively, in view of the fact that the determination whether the MAC addresses match in S306 cannot be executed unless the two MAC addresses are aligned, the broadcast may be started with the reception of the MAC address in S302 as a trigger, and the specific start timing can be variously modified. After the start timing, the communication unit 120 of the terminal apparatus 100 continuously executes the broadcast shown in S304 at a given interval until a given termination condition is satisfied. The following two are examples of the given termination conditions.
The first termination condition is that the MAC addresses are determined to match in S306, and notification processing is performed. When the broadcast is performed at a timing before the connection between the electronic equipment 200 and the access point 300 is successful, the electronic equipment 200 does not transmit the MAC address because the broadcast packet does not reach the electronic equipment 200. When there is another equipment on the network, the MAC address of the other equipment may be returned, but the MAC address matching the MAC address received in S302 is not received. When the matching MAC address is not received, it means that the connection between the electronic equipment 200 and the access point 300 is not confirmed, so the processing unit 110 does not perform notification processing and continues broadcasting. The first termination condition may be considered as a normal termination condition.
The second termination condition is that the broadcast is continued for a given time. The given time here is a time for determining a timeout, and the specific length thereof can be set variously. The given time is preferably long from the viewpoint of reliably completing the Wi-Fi connection, but is preferably short from the viewpoint of not keeping the user waiting. The given time is set to a value depending on the situation, for example, in consideration of the above two points. The processing unit 110 determines that the connection between the electronic equipment 200 and the access point 300 has failed when it is not possible to receive a matching MAC address even after waiting for a given time, and finishes the broadcast. In this case, the processing unit 110 may perform notification processing of notifying a connection failure, or may execute processing to be described later with reference to
As described above, in the method illustrated in
However, since the broadcast packet is a packet that also reaches other equipment in the network, there arises a problem that it is difficult to determine whether the transmission source of the packet to be returned is the electronic equipment 200 or not. In that respect, in the method in
The electronic equipment 200 may hold a plurality of MAC addresses. For example, the electronic equipment 200 can use the first MAC address in the first communication unit 221, and can use the second MAC address different from the first MAC address in the second communication unit 222. In this case, the MAC address to be used is optional. For example, the first MAC address may be transmitted in both S302 and S305, and the second MAC address may be transmitted in both S302 and S305. Alternatively, both the first MAC address and the second MAC address may be transmitted in S302, and any one of the first MAC address and the second MAC address may be transmitted in S305. The same applies to the case where the electronic equipment 200 includes three or more MAC addresses, and when the MAC address transmitted through the BLE connection in S302 is associated with the MAC address transmitted through the Wi-Fi connection in S305, it is possible to use any MAC address for processing.
After the communication unit 120 of the terminal apparatus 100 transmits the SSID in compliance with the second wireless communication scheme, the communication unit 120 receives the data including the identifier broadcasted by the electronic equipment 200 in compliance with the first wireless communication scheme, thereby the identifier is received in compliance with the first wireless communication scheme. In this way, the terminal apparatus 100 can acquire the MAC address of the electronic equipment 200 using the Wi-Fi connection by waiting for the broadcast packet of the electronic equipment 200. Also in this case, since the MAC address of the electronic equipment 200 can be acquired using both the BLE connection and the Wi-Fi connection, appropriate notification processing based on the match determination can be performed.
Specifically, after the transmission of the SSID shown in S207, the processing unit 110 performs standby processing of waiting for a notification of a connection completion from the electronic equipment 200 for a given time (S404). The given time here is a time for determining a timeout, and the specific length thereof can be set variously. For example, the given time is a time of approximately the same length as the time of continuing the broadcast shown in S304 in
When the connection to the access point 300 is established based on the SSID acquired in S207 (S403), the electronic equipment 200 broadcasts its own MAC address to the network using the Wi-Fi connection (S405). When the connection between the electronic equipment 200 and the access point 300 is completed, the broadcast packet transmitted from the electronic equipment 200 can reach the terminal apparatus 100 because the terminal apparatus 100 and the electronic equipment 200 belong to the same network segment. Note that, the broadcast executed in S405 may be performed only once, but may be executed plural times in consideration of a communication error or the like.
When the processing unit 110 of the terminal apparatus 100 receives the broadcast packet from the electronic equipment 200 during the standby processing in S404, the processing unit 110 acquires the MAC address included in the packet. Then, the processing unit 110 determines whether the MAC address received in S402 matches the MAC address received in S405, and performs notification processing when the MAC addresses match (S406).
On the other hand, when the matching MAC address cannot be received during the standby processing in S404, the processing unit 110 determines that the connection between the electronic equipment 200 and the access point 300 has failed. In this case, the processing unit 110 may perform notification processing of notifying a connection failure, or may execute processing to be described later with reference to
As described above, in the method illustrated in
The point that the electronic equipment 200 may hold a plurality of MAC addresses and that the MAC address used for the process can be variously modified are the same as in the example described above with reference to
Also, the electronic equipment 200 attempts a Wi-Fi connection to the access point 300 through the first communication unit 221 using the SSID and the password acquired in S207. When the SSID and the password are appropriate, the Wi-Fi connection is established between the electronic equipment 200 and the access point 300 (S502).
The transmission and reception of the IP address through the BLE connection shown in S501 and the establishment of the Wi-Fi connection shown in S502 can be performed in parallel regardless of the execution order. For example, after the transmission of the SSID in S207, the terminal apparatus 100 continues to transmit the IP address in S501. Also, the terminal apparatus 100 may transmit its own IP address first, and then transmit the SSID.
The processing unit 110 of the terminal apparatus 100 performs notification processing of notifying that the connection between the electronic equipment 200 and the access point 300 is successful when the communication unit 120 received a notification from the electronic equipment 200 in compliance with the first wireless communication scheme within a given time set based on the transmission timing of the IP address or the transmission timing of the SSID. By notifying the IP address of the terminal apparatus 100, Wi-Fi communication between the terminal apparatus 100 and the electronic equipment 200 becomes possible without using a broadcast. Therefore, when compared with the methods shown in
Specifically, the processing unit 110 performs standby processing of waiting for a notification of a connection completion from the electronic equipment 200 for a given time (S503). As can be understood from this process, the method shown in
When the connection to the access point 300 is established based on the SSID acquired in S207 (S502), the electronic equipment 200 transmits a notification notifying a connection completion to the IP address received in S501 using the Wi-Fi connection (S504).
When the processing unit 110 of the terminal apparatus 100 receives a notification from the electronic equipment 200 during the standby processing in S503, the processing unit 110 determines that the Wi-Fi communication with the electronic equipment 200 through the access point 300 has been performed. That is, the processing unit 110 determines that the connection between the electronic equipment 200 and the access point 300 is successful, and executes notification processing of notifying that effect (S505).
When the notification cannot be received during the standby processing in S503, the processing unit 110 determines that the connection between the electronic equipment 200 and the access point 300 has failed. In this case, the processing unit 110 may perform notification processing of notifying a connection failure, or may execute processing to be described later with reference to
In the processing sequence shown in
Alternatively, the notification from the electronic equipment 200 may have a specific attribute. For example, the notification includes information indicating that the electronic equipment 200 has connected to the access point 300. Then, when the communication unit 120 receives the notification within a given time, the processing unit 110 performs notification processing of notifying that the connection between the electronic equipment 200 and the access point 300 is successful.
The possibility that equipment different from the electronic equipment 200 transmits a notification designating the IP address of the terminal apparatus 100 for a purpose other than the notification of a connection success cannot be denied. In that respect, by including information indicating that the electronic equipment 200 is connected to the access point 300 in the notification from the electronic equipment 200, the processing unit 110 can determine for what purpose the notification is transmitted. The processing unit 110 performs notification processing on the condition that the notification is received within the given time and the notification includes information indicating that the electronic equipment 200 has connected to the access point 300. In this way, it is possible to suppress an erroneous determination that the notification from another equipment is the notification from the electronic equipment 200 to be set.
The information indicating that the electronic equipment 200 is connected to the access point 300 may be recognized by both the terminal apparatus 100 and the electronic equipment 200 to that effect, and the specific form of the information does not matter.
As described above, in the method shown in
Then, the communication unit 120 of the terminal apparatus 100 receives the notification including the identifier of the electronic equipment 200 from the electronic equipment 200 in compliance with the first wireless communication scheme. The processing unit 110 performs notification processing of notifying that the connection between the electronic equipment 200 and the access point 300 is successful when the communication unit 120 receives the notification within a given time and determines that the identifier included in the notification matches the identifier received in compliance with the second wireless communication scheme. In this way, it is possible to accurately determine whether the transmission source of the notification is the electronic equipment 200 to be set, while suppressing the compression of the network band.
Specifically, the processing unit 110 performs standby processing of waiting for a notification of a connection completion from the electronic equipment 200 for a given time (S605). When the connection to the access point 300 is established based on the SSID acquired in S207 (S604), the electronic equipment 200 transmits a notification notifying a connection completion to the IP address received in S601 using the Wi-Fi connection (S606). The notification transmitted in S606 includes the MAC address of the electronic equipment 200.
When the processing unit 110 of the terminal apparatus 100 receives a notification from the electronic equipment 200 during the standby processing in S605, the processing unit 110 acquires the MAC address included in the notification. Then, the processing unit 110 determines whether the MAC address received in S603 matches the MAC address received in S606, and performs notification processing when the MAC addresses match (S607).
When the matching MAC address cannot be received during the standby processing in S605, the processing unit 110 determines that the connection between the electronic equipment 200 and the access point 300 has failed. In this case, the processing unit 110 may perform notification processing of notifying a connection failure, or may execute processing to be described later with reference to
Hereinafter, some modifications will be described.
As described above with reference to
When a timeout is detected, the processing unit 110 may perform notification processing of notifying that the connection between the electronic equipment 200 and the access point 300 has failed. However, it is difficult for the user to take appropriate measures even if the user is simply notified of the failure. Therefore, the processing unit 110 may perform processing corresponding to the cause of the failure or may present an alternative plan.
The electronic equipment 200 answers the cause of failure using the BLE connection in response to the inquiry in the S702 (S703). For example, when the connection to the access point 300 has failed due to an error of the password, the communication unit 220 of the electronic equipment 200 is capable of recognizing that effect. Therefore, the electronic equipment 200 responds, in S703, with information indicating whether the failure is due to an erroneous input of the password.
When the communication unit 120 of the terminal apparatus 100 receives a notification that the connection between the electronic equipment 200 and the access point 300 has failed from the electronic equipment 200 in compliance with the second wireless communication scheme, the processing unit 110 performs notification processing of urging a re-input of the password corresponding to the SSID (S704). More specifically, as shown in
In addition, when the notification indicating that the cause of the connection failure is not the erroneous input of the SSID is received, various processes by the processing unit 110 are conceivable. For example, the processing unit 110 performs notification processing of urging a direct connection between the electronic equipment 200 and the terminal apparatus 100. The direct connection means that the terminal apparatus 100 and the electronic equipment 200 are connected to each other not through the external access point 300. Hereinafter, this connection mode is referred to as a direct connection. When the direct connection is performed, one of the terminal apparatus 100 and the electronic equipment 200 activates an internal access point, and the other connects to the internal access point. In this way, the transmission and reception of data using Wi-Fi connection become possible between the terminal apparatus 100 and the electronic equipment 200 not through the external access point 300.
For example, the communication unit 120 of the terminal apparatus 100 transmits a request for validating the internal access point to the electronic equipment 200 through the BLE connection. When receiving the request, the electronic equipment 200 performs processing for starting the internal access point. The terminal apparatus 100 performs connection to the electronic equipment 200 using the SSID and the password corresponding to the internal access point of the electronic equipment 200.
For example, the communication unit 120 of the terminal apparatus 100 transmits a request for displaying the SSID and the password of the internal access point through the BLE connection to the electronic equipment 200. The electronic equipment 200 displays the SSID and the password corresponding to the internal access point on the display unit 230. The user browses the display unit 230 and inputs the SSID and the password using the operation unit 140 of the terminal apparatus 100. Thereby, the terminal apparatus 100 and the electronic equipment 200 are directly connected to each other. Although here, an example of displaying the SSID and the password itself on a display unit 230 is shown, a QR code (registered trademark) representing the SSID and the password may be displayed. The terminal apparatus 100 acquires the SSID and the password by imaging the QR code using the imaging unit.
Alternatively, the direct connection between the terminal apparatus 100 and the electronic equipment 200 may be performed using Wi-Fi direct (WFD). When the WFD is used, connection can be easily realized by specifying the device name of the equipment which is the connection target without directly inputting the SSID or the password by the user. For example, the communication unit 120 of the terminal apparatus 100 transmits a request for displaying a device name to the electronic equipment 200 through the BLE connection. The electronic equipment 200 displays its own device name on the display unit 230. The user browses the display unit 230 and uses the operation unit 140 of the terminal apparatus 100 to select a device with the displayed device name. Thereby, the terminal apparatus 100 and the electronic equipment 200 are directly connected to each other.
Alternatively, when the notification indicating that the cause of the connection failure is not the erroneous input of the SSID is received, the processing unit 110 performs notification processing of urging an execution of cloud printing. Cloud printing refers to processing of transmitting print data from the terminal apparatus 100 to the electronic equipment 200 through the Internet and executing printing. As shown in S205 of
Alternatively, when the notification indicating that the cause of the connection failure is not the erroneous input of the SSID is received, the processing unit 110 may perform notification processing of urging a termination of the connection processing between the electronic equipment 200 and the access point 300.
In the example of
Further,
Further, in
However, the direct connection between the terminal apparatus 100 and the electronic equipment 200 is not limited to this. For example, in
When the terminal apparatus 100 and the access point 300 are not connected to each other, even though connection between the electronic equipment 200 and the access point 300 is successful, communication between the terminal apparatus 100 and the electronic equipment 200 conforming to the Wi-Fi standards cannot be performed. Therefore, when it is determined that the terminal apparatus 100 and the access point 300 are not connected to each other, the processing unit 110 may perform notification processing of urging a direct connection between the terminal apparatus 100 and the electronic equipment 200. The specific processing after the notification processing is as described above.
In the present embodiment, as described with reference to
One of the purposes of connecting the electronic equipment 200 and the access point 300 is to transmit and receive data between the terminal apparatus 100 and the electronic equipment 200 using Wi-Fi. When communication by the broadcast described above or communication designating an IP address is possible, data can be transmitted and received between the terminal apparatus 100 and the electronic equipment 200 using Wi-Fi not through an external network such as the Internet. That is, the above condition can be considered as a condition for determining whether desired communication can be performed.
When the terminal apparatus 100 and the electronic equipment 200 are connected to the same access point, both of the above two conditions are satisfied. However, even if the terminal apparatus 100 and the electronic equipment 200 are not connected to the same access point, the condition may be satisfied. Hereinafter, two cases will be described.
For example, a case where the access point 300 is a layer 2 switch (L2SW) that does not have a router function is conceivable. And, a network in which a first access point that is L2SW and a second access point that is L2SW are connected without a router is conceivable. For example, a network may be considered in which the first access point and the second access point are connected to a common hub, and the hub is connected to a router. When the terminal apparatus 100 is connected to the first access point and the electronic equipment 200 is connected to the second access point, since the terminal apparatus 100 and the electronic equipment 200 belong to the same network segment, the broadcast packet transmitted by one equipment can reach the other equipment.
In addition, in an internal network such as a company intranet, there are many cases where a plurality of network segments are set. In the case of communication designating an IP address, there is a case where it is possible to transmit a packet from equipment belonging to the first network segment to equipment belonging to the second network segment through a router, although it also depends on the method of IP address assignment by the DHCP server. It is conceivable a case where the terminal apparatus 100 is connected to the access point belonging to the first network segment and the electronic equipment 200 is connected to the access point belonging to the second network segment. In this case, since the two network segments are segments of the same internal network, a packet transmitted by the electronic equipment 200 designating the IP address of the terminal apparatus 100 can reach the terminal apparatus 100.
In both cases described above, the terminal apparatus 100 and the electronic equipment 200 are connected to different access points. However, as long as the above conditions are satisfied, Wi-Fi communication between the terminal apparatus 100 and the electronic equipment 200 is possible, and the purpose of connecting the electronic equipment 200 and the access point 300 is achieved. Therefore, in the present embodiment, these cases are also permitted, and the processing unit 110 may determine that the connection between the electronic equipment 200 and the access point 300 is successful.
As described above, the state in which the terminal apparatus 100 and the electronic equipment 200 are connected to the same access point 300 is an example in which it is determined that the connection is successful, but the connection mode realized by the method of the present embodiment is not limited to this, and various modifications are possible. The processing unit 110 of the terminal apparatus 100 according to the present embodiment may determine whether the connection is successful based on whether communication between the terminal apparatus 100 and the electronic equipment 200 is possible, and it is not necessary to determine the specific connection mode.
Moreover, an application object of the method of the present embodiment is not limited to the terminal apparatus 100 described above. For example, as illustrated in
Moreover, each part of the terminal apparatus 100 of the present embodiment may be implemented as a module of the program which operates on a processor. For example, the program includes a communication control module that controls the communication unit 120 and a processing module. The communication control module performs processing of transmitting the SSID corresponding to the access point 300 to be connected in the first wireless communication scheme to the electronic equipment 200 in compliance with the second wireless communication scheme, and receiving the identifier of the electronic equipment 200 from the electronic equipment 200 in compliance with the second wireless communication scheme. The communication unit 120 receives the identifier of the electronic equipment 200 transmitted by the electronic equipment 200 by the first wireless communication scheme, and the processing module performs determination whether the identifier received by the first wireless communication scheme and the identifier received by the second wireless communication scheme match. When it is determined that the two identifiers match, the processing module performs notification processing of notifying that the connection between the access point 300 and the electronic equipment 200 is successful.
Alternatively, the communication control module performs processing of transmitting the SSID corresponding to the access point 300 to be connected in the first wireless communication scheme to the electronic equipment 200 by the second wireless communication scheme, and transmitting the IP address of the terminal apparatus 100 to the electronic equipment 200 in compliance with the second wireless communication scheme. When the communication unit 120 receives a notification from the electronic equipment 200 in compliance with the first wireless communication scheme within a given time set based on the transmission timing of the IP address or the transmission timing of the SSID, the processing module performs notification processing of notifying that the connection between the electronic equipment 200 and the access point 300 is successful.
Moreover, the program, which implements processing which each part of the terminal apparatus 100 of the present embodiment performs, can be stored in the information storage medium which is a medium which is readable by a computer, for example. The information storage medium can be realized by, for example, an optical disk, a memory card, an HDD, or a semiconductor memory. The semiconductor memory is, for example, a read only memory (ROM). The processing unit 110 performs various processes of the present embodiment based on programs and data stored in the information storage medium. That is, a program for causing a computer to function as each unit of the terminal apparatus 100 of the present embodiment is stored in the information storage medium. The computer is an apparatus including an input device, a processing unit, a storage unit, and an output unit. The program is a program for causing a computer to execute the processing of each unit.
Further, the method of the present embodiment can be applied to the control method of the terminal apparatus 100 which executes a part or all of the steps shown in
As described above, the terminal apparatus of the present embodiment includes the communication unit that communicates with the electronic equipment, and the processing unit that controls the communication unit. The communication unit transmits the SSID corresponding to the access point to be connected in the first wireless communication scheme of the electronic equipment to the electronic equipment in compliance with the second wireless communication scheme, and receives the identifier of the electronic equipment from the electronic equipment in compliance with the second wireless communication scheme. The processing unit performs notification processing of notifying that the connection between the electronic equipment and the access point has succeeded, when the communication unit receives the identifier of the electronic equipment transmitted by the electronic equipment in compliance with the first wireless communication scheme after the transmission of the SSID in compliance with the second wireless communication scheme, and it is determined that the identifier received in compliance with the first wireless communication scheme matches the identifier received in compliance with the second wireless communication scheme.
According to the method of the present embodiment, notification processing is performed in a case where the connection setting in the first wireless communication scheme of the electronic equipment using the terminal apparatus is performed, and when the identifier matching the identifier received in compliance with the second wireless communication scheme is received in compliance with the first wireless communication scheme. In this way, when the connection between the electronic equipment and the access point is successful, the terminal apparatus can notify that effect, thereby convenience can be improved.
Further, in the present embodiment, the communication unit may broadcast the acquisition request for the identifier to the network in compliance with the first wireless communication scheme after transmitting the SSID in compliance with the second wireless communication scheme, and may receive the identifier of the electronic equipment as a response to the acquisition request in compliance with the first wireless communication scheme.
In this way, it is possible to receive the identifier of the electronic equipment according to the first wireless communication scheme by making a request from the terminal apparatus side.
In the present embodiment, the communication unit may receive the identifier in compliance with the first wireless communication scheme, by receiving data including the identifier broadcasted by the electronic equipment after transmitting the SSID in compliance with the second wireless communication scheme.
In this way, by waiting for a broadcast from the electronic equipment, it becomes possible to receive the identifier of the electronic equipment in compliance with the first wireless communication scheme.
Further, the communication unit of the terminal apparatus of the present embodiment transmits the SSID corresponding to the access point which is the connection target in the first wireless communication scheme of the electronic equipment to the electronic equipment in compliance with the second wireless communication scheme, and transmits the IP address of the terminal apparatus to the electronic equipment in compliance with the second wireless communication scheme. The processing unit performs notification processing of notifying that the connection between the electronic equipment and the access point is successful, when the communication unit receives a notification from the electronic equipment in compliance with the first wireless communication scheme within a given time set based on the transmission timing of the IP address or the transmission timing of the SSID.
According to the method of the present embodiment, the notification processing is performed in a case of performing connection setting in the first wireless communication scheme of the electronic equipment using the terminal apparatus, when the notification is given to the own IP address notified in compliance with the second wireless communication scheme. In this way, when the connection between the electronic equipment and the access point is successful, the terminal apparatus can notify that effect, thereby convenience can be improved.
In the present embodiment, the communication unit may receive the identifier of the electronic equipment from the electronic equipment in compliance with the second wireless communication scheme, and may receive the notification including the identifier of the electronic equipment from the electronic equipment in compliance with the first wireless communication scheme. The processing unit may perform notification processing when the communication unit receives the notification within a given time, and determines that the identifier included in the notification and the identifier received in compliance with the second wireless communication scheme match.
In this way, by using the IP address and the identifier together, it is possible to suppress the pressure of the network band, and accurately determine whether the transmission source of the notification is the electronic equipment to be set.
In the present embodiment, the notification may include information indicating that the electronic equipment has connected to the access point. The processing unit performs notification processing when the communication unit receives the notification within a given time.
In this way, by using the IP address and the identifier together, it is possible to suppress the compression of the network bandwidth, and to determine whether the transmission source of the notification is the electronic equipment to be set using the notification attribute.
In the present embodiment, the processing unit may perform notification processing of urging re-input of a password corresponding to the SSID, when the communication unit transmits the SSID to the electronic equipment, and then receives the notification that connection between the electronic equipment and the access point has failed from the electronic equipment in compliance with the second wireless communication scheme.
In this way, when it is determined that the connection between the electronic equipment and the access point has failed, it is possible to urge the user to take appropriate measures.
Further, in the present embodiment, processing unit may perform notification processing of urging direct connection between the electronic equipment and the terminal apparatus, when the communication unit transmits the SSID to the electronic equipment, and then receives a notification that connection between the electronic equipment and the access point has failed from the electronic equipment by the second wireless communication scheme.
In this way, when it is determined that the connection between the electronic equipment and the access point has failed, it is possible to urge the user to take appropriate measures.
Further, in the present embodiment, when the processing unit determines that the connection between the electronic equipment and the access point has failed, the communication unit may transmit an inquiry about the cause why the connection between the electronic equipment and the access point is unsuccessful to the electronic equipment in compliance with the second wireless communication scheme.
In this way, it is possible to inquire the cause why the connection between the electronic equipment and the access point is unsuccessful from the terminal apparatus side.
Further, in the present embodiment, the communication unit may receive the SSID list acquired by scanning processing using the first wireless communication scheme by the electronic equipment, from the electronic equipment in compliance with the second wireless communication scheme, and may transmit the SSID selected by the user from the SSID list to the electronic equipment in compliance with the second wireless communication scheme as an SSID corresponding to the access point. The communication unit may also transmit the password corresponding to the SSID to the electronic equipment in compliance with the second wireless communication scheme.
In this way, the connection setting of the electronic equipment can be appropriately performed using the terminal apparatus.
Moreover, the communication system of the present embodiment includes a terminal apparatus described in any of the above and electronic equipment.
The program according to the present embodiment causes the computer to execute a process of transmitting the SSID corresponding to the access point to be connected in the first wireless communication scheme of the electronic equipment to the electronic equipment in compliance with the second wireless communication scheme. The program causes the computer to execute the process of receiving the identifier of the electronic equipment from the electronic equipment in compliance with the second wireless communication scheme, and the program causes the computer to execute notification processing of notifying that connection between the electronic equipment and the access point has succeeded when, after the SSID is transmitted in compliance with the second wireless communication scheme, receives the identifier of the electronic equipment transmitted by the electronic equipment is received in compliance with the first wireless communication scheme, and determines that the identifier received in compliance with the first wireless communication scheme matches the identifier received in compliance with the second wireless communication scheme.
The program according to the present embodiment causes the computer to execute a process of transmitting the SSID corresponding to the access point to be connected in the first wireless communication scheme of the electronic equipment to the electronic equipment in compliance with the second wireless communication scheme. The program also causes the computer to execute a process of transmitting the IP address of the terminal apparatus to the electronic equipment in compliance with the second wireless communication scheme. In addition, when the program receives a notification from the electronic equipment in compliance with the first wireless communication scheme within a given time set based on the transmission timing of the IP address or the transmission timing of the SSID, the program causes the computer to execute notification processing of notifying that the connection between the electronic equipment and the access point has succeeded.
