An information processing apparatus 101 and a communication apparatus 151 included in a communication system according to this embodiment will be described. In this embodiment, a smartphone is exemplified as the information processing apparatus 101 but the present invention is not limited to this. For example, as the information processing apparatus 101, various kinds of apparatuses such as a portable terminal, a Personal Computer (PC), a tablet terminal, a Personal Digital Assistant (PDA), and a digital camera are applicable. Furthermore, a printer is exemplified as the communication apparatus 151 but the present invention is not limited to this, and various kinds of apparatuses are applicable as long as they can perform wireless communication with the information processing apparatus 101. For example, concerning a printer, an inkjet printer, a full-color laser beam printer, a monochrome printer, and the like are applicable. Furthermore, not only a printer but also a copying machine, a facsimile apparatus, a portable terminal, a smartphone, a laptop, a tablet terminal, a PDA, a digital camera, a music playback device, a television, a smart speaker, and the like are applicable. In addition, a multi-function peripheral having a plurality of functions such as a copying function, a FAX function, and a print function is applicable.
First, components of the information processing apparatus 101 of this embodiment and the communication apparatus 151 which can communicate with the information processing apparatus 101 of this embodiment will be described with reference to a block diagram shown in
The information processing apparatus 101 includes an input interface 102, a CPU 103, a ROM 104, a RAM 105, an external storage device 106, an output interface 107, a display unit 108, a communication unit 110, a short distance wireless communication unit 111, and an image capturing unit 112. The CPU 103, the ROM 104, the RAM 105, and the like form a computer of the information processing apparatus 101 for executing a program.
The input interface 102 is an interface for accepting data input and instruction operations from the user when an operation unit such as a keyboard 109 is operated. Note that the operation unit may include a physical keyboard and physical buttons, or may include a software keyboard and software buttons displayed on the display unit 108. That is, the input interface 102 may accept input from the user via the display unit 108.
The CPU 103 is a system control unit and controls the whole information processing apparatus 101 such as execution of an application program. The ROM 104 stores permanent data such as control programs to be executed by the CPU 103, data tables, and an embedded operating system (to be referred to as an OS hereinafter) program. In this embodiment, the control programs stored in the ROM 104 perform software execution control such as scheduling, task switch, and interrupt processing under the management of the embedded OS stored in the ROM 104.
The RAM 105 is formed by a Static Random Access Memory (SRAM) or the like, which needs a backup power supply. Note that the RAM 105 can store important data such as program control variables without volatilization because the data are held by a primary battery (not shown) for data backup. In addition, a memory area for storing setting information of the information processing apparatus 101, management data of the information processing apparatus 101, and the like is also provided in the RAM 105. Furthermore, the RAM 105 is also used as the main memory and the work memory of the CPU 103.
The external storage device 106 stores an application program (setup application) configured to execute a network setup of the communication apparatus 151, a printer management application, a print information generation program that generates print information interpretable by the communication apparatus 151, and the like. Each program is stored in the external storage device 106 by being installed from an external server (not shown) by, for example, Internet communication via the communication unit 110. A service registration application is an application program configured to transmit information acquired from the communication apparatus 151, personal information of the user acquired by the information processing apparatus 101, and the like to a service management server (not shown). The application program (setting application) configured to execute a network setup of the communication apparatus 151 is an application program configured to set an access point as the connection destination of the communication apparatus 151. The printer management application is an application configured to manage information of the printer. Note that the service registration application, the setting application, the printer management application, and the print information generation program (print application) may be formed as one application.
The output interface 107 is an interface configured to perform control for causing the display unit 108 to display data or make a notification concerning the state of the information processing apparatus 101. The display unit 108 is formed by a Light-Emitting Diode (LED), a Liquid Crystal Display (LCD), or the like and displays data or makes a notification concerning the state of the information processing apparatus 101. The image capturing unit 112 is, for example, a camera that captures the outside.
The communication unit 110 is a component connected to the apparatus such as the communication apparatus 151 or an access point 131 to execute data communication. For example, the communication unit 110 can be connected to an access point (not shown) in the communication apparatus 151. The communication unit 110 includes, as an access point in the information processing apparatus 101, an access point for connection to the apparatus such as the communication apparatus 151. This access point is generally called tethering. Note that a communication unit 156 of the communication apparatus 151 can be connected to the access point. When the communication unit 110 enables the access point, the information processing apparatus 101 operates as the access point. When the communication unit 156 and the access point in the communication unit 110 are connected, the information processing apparatus 101 and the communication apparatus 151 can communicate with each other. If the communication unit 110 of the information processing apparatus 101 is connected to the Internet, the communication apparatus 151 can also be connected to the Internet via the information processing apparatus 101. Note that in this embodiment, the information processing apparatus 101 can communicate with the communication apparatus 151 via an external apparatus existing outside the information processing apparatus 101 and the communication apparatus 151. Note that examples of the external apparatus include an external access point (the access point 131 or the like) existing outside the information processing apparatus 101 and the communication apparatus 151, and an apparatus, other than the access point, that can relay communication. For example, a device such as a wireless LAN router is used as the access point 131. The method of connecting the information processing apparatus 101 and the communication apparatus 151 via the external access point is called an infrastructure connection method.
The short distance wireless communication unit 111 is a component wirelessly connected to the apparatus such as the communication apparatus 151 in a short distance to execute data communication, and performs communication by a communication method different from that of the communication unit 110. The short distance wireless communication unit 111 can be connected to a short distance wireless communication unit 157 in the communication apparatus 151. As the communication method, for example, Near Field Communication (NFC), Bluetooth® Classic, Bluetooth Low Energy (BLE), a Wi-Fi Aware, or the like is used.
The communication apparatus 151 includes a ROM 152, a RAM 153, a CPU 154, a print engine 155, the communication unit 156, the short distance wireless communication unit 157, and a display unit 158. The ROM 152, the RAM 153, the CPU 154, and the like form a computer of the communication apparatus 151 for executing a program.
The communication unit 156 includes, as the access point in the communication apparatus 151, an access point for connection to the external apparatus such as the information processing apparatus 101. Note that the access point can be connected to the communication unit 110 of the information processing apparatus 101. If the communication unit 156 enables the access point, the communication apparatus 151 operates as the access point. Note that the communication unit 156 may directly, wirelessly be connected to the information processing apparatus 101 or may wirelessly be connected to the information processing apparatus 101 via the access point 131. The wireless communication method used by the communication unit 156 is, for example, a communication standard based on the IEEE 802.11 series. The communication unit 156 may include a hardware component functioning as an access point or may operate as an access point by software for functioning as an access point.
A mode and a connection method of executing wireless communication using the communication unit 156 will now be described.
Direct connection indicates a form in which apparatuses are wirelessly connected directly (that is, by Peer to Peer) without intervention of an external apparatus such as the AP 131. Direct connection is also called Peer to Peer connection (P2P connection). As one connection mode, the communication apparatus 151 can operate in a mode (direct connection mode) for communication by direct connection. In Wi-Fi communication, the mode for communication by direct connection includes a plurality of modes such as a software AP mode and a Wi-Fi Direct (WFD) mode.
A mode in which direct connection is executed by WFD is called a WFD mode. WFD is a standard developed by Wi-Fi Alliance and is a standard included in the IEEE 802.11 communication standards. In the WFD mode, a device serving as a communication partner is searched for by a device search command, then the roles of a P2P group owner (GO) and P2P client are decided, and remaining wireless connection processing is performed. The group owner corresponds to a Wi-Fi master station (master unit), and the client corresponds to a Wi-Fi slave station (slave unit). This role making corresponds to, for example, Go Negotiation in P2P. Note that in the WFD mode in a state before role making is performed, the communication apparatus 151 is neither the master station nor the slave station. More specifically, first, one of devices to communicate with each other issues a device search command and searches for a device to be connected in the WFD mode. After the other device serving as a communication partner is found, the devices confirm information about services and functions that can be supplied by the respective devices. Note that the device supply information confirmation is an option and is dispensable. The device supply information confirmation phase corresponds to, for example, P2P Provision Discovery. Then, the devices confirm the device supply information and decide, as roles, which device serves as a P2P client and which device serves as a P2P group owner. After the client and the group owner are decided, the devices exchange parameters for performing WFD communication. Based on the exchanged parameters, the P2P client and the P2P group owner perform remaining wireless connection processing and IP connection processing. Note that in the WFD mode, the communication apparatus 151 may always operate as the GO without executing the above-described GO Negotiation. That is, the communication apparatus 151 may operate in the WFD mode that is an Autonomous GO mode. The state in which the communication apparatus 151 operates in the WFD mode is, for example, a state in which WFD connection is not established but the communication apparatus 151 operates as the GO, or a state in which WFD connection is established and the communication apparatus 151 operates as the GO.
In the software AP mode, one device (for example, the information processing apparatus 101) among devices (for example, the information processing apparatus 101 and the communication apparatus 151) to communicate with each other serves as a client that plays a role of requesting various services. The other device implements the function of an access point in Wi-Fi by software setting. The software AP corresponds to a Wi-Fi master station, and the client corresponds to a Wi-Fi slave station. In the software AP mode, the client searches for a device serving as a software AP by a device search command. After the software AP is found, the client and the software AP perform remaining wireless connection processing (establishment of wireless connection and the like) and then IP connection processing (assignment of an IP address and the like). Note that commands and parameters transmitted/received when implementing wireless connection between the client and the software AP suffice to be those defined by the Wi-Fi standard, and a description thereof will be omitted here.
In this embodiment, in a case where the communication apparatus 151 establishes and maintains direct connection, it operates as a master station in a network to which the communication apparatus 151 belongs. Note that the master station is an apparatus that creates a wireless network, and is an apparatus that provides a slave station with parameters used in connection to the wireless network. The parameters used in connection to the wireless network are, for example, parameters about a channel used by the master station. The slave station receives the parameters and is then connected to the wireless network created by the master station using the channel used by the master station. In the direct connection mode, the communication apparatus 151 operates as the master station and can thus decide a specific frequency band and channel to be used for communication in the direct connection method. In this embodiment, the communication apparatus 151 can use a channel corresponding to the 2.4-GHz frequency band and a channel corresponding to the 5-GHz frequency band for communication in the direct connection method.
Infrastructure connection is a connection form in which devices (for example, the information processing apparatus 101 and the communication apparatus 151) to communicate with each other are connected to an access point (for example, the AP 131) that controls a network of the devices, and the devices communicate with each other via the access point. As one connection mode, the communication apparatus 151 can operate in a mode (infrastructure connection mode) for communication by infrastructure connection.
In infrastructure connection, each device searches for an access point by a device search command. After an access point is found, the device and the access point perform remaining wireless connection processing (establishment of wireless connection and the like) and then IP connection processing (assignment of an IP address and the like). Note that commands and parameters transmitted/received when implementing wireless connection between the device and the access point suffice to be those defined by the Wi-Fi standard, and a description thereof will be omitted here.
In this embodiment, when the communication apparatus 151 operates in infrastructure connection, the AP 131 operates as a master station and the communication apparatus 151 operates as a slave unit. That is, in this embodiment, infrastructure connection means connection between the communication apparatus 151 operating as a slave unit and the apparatus operating as a master unit. In a case where the communication apparatus 151 establishes infrastructure connection and the information processing apparatus 101 also establishes infrastructure connection to the AP 131, the communication apparatus 151 and the information processing apparatus 101 can communicate with each other via the AP 131. Since the AP 131 decides a channel to be used for communication in infrastructure connection, the communication apparatus 151 executes communication in infrastructure connection using the channel decided by the AP 131. In this embodiment, the communication apparatus 151 can use a channel corresponding to the 2.4-GHz frequency band and a channel corresponding to the 5-GHz frequency band for communication in infrastructure connection. Note that the communication apparatus 151 can also use a channel corresponding to the DFS band in the 5-GHz frequency band for communication in infrastructure connection. Note also that to communicate with the communication apparatus 151 via the AP 131, the information processing apparatus 101 needs to recognize that the communication apparatus 151 belongs to a network which is formed by the AP 131 and to which the information processing apparatus 101 belongs.
In this embodiment, a state in which the information processing apparatus 101 and the communication apparatus 151 are simply connected to the same AP is considered as an infrastructure connection state. That is, in the infrastructure connection state, the information processing apparatus 101 and the communication apparatus 151 need only be connected to the same AP, and need not recognize that the partner apparatus belongs to the network to which the self-apparatus belongs.
The communication apparatus 151 can operate in the network setup mode. A trigger for the communication apparatus 151 to start an operation in the network setup mode may be, for example, the pressing of a network setup mode button by the user or activation (power-on) of the communication apparatus 151 for the first time after arrival. The network setup mode button may be a hardware (physical) button of the communication apparatus 151 or a software button displayed on the display unit 158 by the communication apparatus 151.
When the communication apparatus 151 starts an operation in the network setup mode, it enables Wi-Fi communication. More specifically, as Wi-Fi communication enabling processing, the communication apparatus 151 enables an internal AP (connection setting AP) of the communication apparatus 151 that is dedicated to the network setup mode. Then, the communication apparatus 151 can establish Wi-Fi direct connection to the information processing apparatus 101. Assume that connection information (Service Set Identifier (SSID) and password) for connection to the connection setting AP is held in advance in a setup application installed in the information processing apparatus 101, and the information processing apparatus 101 recognizes in advance the connection information for connection to the connection setting AP. Therefore, unlike connection information of an AP enabled in the direct connection mode, the connection information for connection to the connection setting AP cannot be changed arbitrarily by the user. Note that in the network setup mode, the communication apparatus 151 may be connected to the information processing apparatus 101 by not normal Wi-Fi but Wi-Fi Direct (WFD). That is, the communication apparatus 151 may operate as a group owner, and receive a setting command from the information processing apparatus 101 by WFD communication. Alternatively, the communication apparatus 151 may be connected to the information processing apparatus 101 by Bluetooth in the network setup mode. Bluetooth includes Bluetooth Classic and Bluetooth Low Energy (BLE). That is, for example, the communication apparatus 151 may operate as a slave apparatus in BLE in the network setup mode, and receive a setting command from the information processing apparatus 101 by BLE communication. Furthermore, in the network setup mode, the communication apparatus 151 may be able to execute both a network setup by Wi-Fi and a network setup by BLE. That is, when the communication apparatus 151 starts an operation in the network setup mode, it may enable both Wi-Fi communication and BLE communication. More specifically, when the communication apparatus 151 starts an operation in the network setup mode, it may enable both the connection setting AP and an advertising state in which BLE connection is enabled by transmitting advertising information by BLE.
When the communication apparatus 151 operates in the network setup mode, it controls the communication unit 156 to operate as a setup access point (connection setting AP) that is enabled only during an operation in the network setup mode. The setup access point is an access point different from that enabled in the above-described software AP mode. Assume that the SSID of the setup access point includes a predetermined character string recognizable by the setting application of the information processing apparatus 101.
Assume that the communication apparatus 151 operating in the network setup mode uses a predetermined communication protocol (setup communication protocol) in communication with the information processing apparatus 101 connected to the setup access point. More specifically, the setup communication protocol is, for example, Simple Network Management Protocol (SNMP).
If a predetermined time elapses after the communication apparatus 151 starts an operation in the network setup mode, the communication apparatus 151 stops the operation in the network setup mode and disables the setup access point. Furthermore, even when the connection information for connection to the AP 131 and a change instruction of the wireless communication operation mode are received from the information processing apparatus 101 in the network setup mode, the setup access point is disabled. Assume that the setup access point is an access point that does not require a password for connection. Note that the setup access point may be an access point that requires a password. In this case, a password used for connection to the setup access point is a fixed password (unchangeable by the user) that is grasped in advance by the setting application.
The communication unit 156 is assigned with a Media Access Control Address (MAC address). The MAC address is an identifier used to identify the communication unit, and is uniquely assigned to each communication unit in all the apparatuses including the communication apparatus and the information processing apparatus. Therefore, the MAC address is often used to identify the individual apparatus. In this embodiment, the identifier used to identify the apparatus will be referred to as apparatus identification information hereinafter. That is, the MAC address is an example of the apparatus identification information. In this embodiment, the MAC address is used as the apparatus identification information. However, the present invention is not limited to this. For example, a manufacturing number (serial number) assigned to the communication apparatus 151 may be used.
The short distance wireless communication unit 157 is a component wirelessly connected to the apparatus such as the information processing apparatus 101 in a short distance, and can be connected to, for example, the short distance wireless communication unit 111 in the information processing apparatus 101. As the communication method, for example, NFC, Bluetooth Classic, BLE, Wi-Fi Aware, or the like is used.
The RAM 153 is formed by an SRAM or the like, which needs a backup power supply. Note that the RAM 153 can store important data such as program control variables without volatilization because the data are held by a primary battery (not shown) for data backup. In addition, a memory area for storing setting information of the communication apparatus 151, management data of the communication apparatus 151, and the like is also provided in the RAM 153. Furthermore, the RAM 153 is used as the main memory and the work memory of the CPU 154 and a reception buffer to temporarily store print information received from the information processing apparatus 101 or the like or store various kinds of information.
The ROM 152 stores permanent data such as control programs to be executed by the CPU 154, data tables, and an OS program. In this embodiment, the control programs stored in the ROM 152 perform software execution control such as scheduling, task switch, and interrupt processing under the management of the embedded OS stored in the ROM 152. The ROM 152 also stores the serial number for identifying the communication apparatus 151. The serial number is uniquely assigned to identify the communication apparatus 151 by the manufacturer of the communication apparatus 151. The serial number can also be used as the apparatus identification information that can be used to identify the communication apparatus 151. In a case where the communication apparatus 151 is a printer, the use status and remaining amount of ink are collected from the print engine 155 and stored in the ROM 152. The CPU 154 is a system control unit and controls the whole communication apparatus 151.
Based on information stored in the RAM 153 or a print job received from the information processing apparatus 101 or the like, the print engine 155 forms an image on a print medium such as a paper sheet by applying a printing material such as ink onto the print medium, and outputs the print result. Note that in general, the data amount of the print job transmitted from the information processing apparatus 101 or the like is large, and thus it is necessary to use, for communication of the print job, a communication method that allows high-speed communication. Therefore, the communication apparatus 151 receives the print job via the communication unit 156 that can perform communication at a speed higher than that of the short distance wireless communication unit 157. The display unit 158 is, for example, a panel, and displays data or makes a notification concerning the state of the communication apparatus 151.
Note that a memory such as an external HDD or an SD card may be attached as an optional device to the communication apparatus 151, and information stored in the communication apparatus 151 may be stored in the memory.
After P2P connection or infrastructure connection by Wi-Fi is established between the information processing apparatus 101 and the communication apparatus 151 by connection setting processing in the above-described network setup mode, the information processing apparatus 101 and the communication apparatus 151 can communicate with each other via the established connection. More specifically, for example, the information processing apparatus 101 can transmit, to the communication apparatus 151 via the established connection, a print job for causing the communication apparatus 151 to execute printing or a scan job for causing the communication apparatus 151 to execute a scan.
In this embodiment, the setup application operating on the information processing apparatus 101 performs guidance display of the use of the password copy function of the AP that is the function of the OS. Then, the setup application causes the information processing apparatus 101 to execute the connection setting processing using a password acquired by the password copy function.
In step S601, the CPU 103 performs connection to the communication apparatus 151 in the network setup mode. The network setup mode is a mode in which the communication apparatus 151 operates as the setup AP using a predetermined SSID and password. The communication apparatus 151 may automatically be activated as the setup AP at the time of an initial setup (at the time of arrival or the like). In this embodiment, the communication apparatus 151 automatically operates as the setup AP at the time of an initial setup. However, the user may perform an operation on the main body panel of the communication apparatus 151 or a main body button operation to cause the communication apparatus 151 to operate in the network setup mode. The CPU 103 detects the predetermined SSID to perform connection to the communication apparatus 151 in the network setup mode.
In step S602, the CPU 103 transmits an instruction to execute a search for an access point around the communication apparatus 151 connected in step S601. Then, the CPU 103 acquires a search result list of access points from the communication apparatus 151. Note that the acquired list is a list of one or a plurality of access points which are found by executing an AP search by the communication apparatus 151 and to which the communication apparatus 151 is connectable. For example, the instruction to execute a search for an access point is executed by designating Management Information Base (MIB) for access point execution instruction using a communication protocol of Simple Network Management Protocol (SNMP). The processing of acquiring the search result list of the access points is also executed by SNMP an MIB from the information processing apparatus 101 to the communication apparatus 151. Note that SNMP and MIB are used in this embodiment but another communication protocol and another data format may be used.
In step S603, the CPU 103 displays, on the display unit 108, a connection destination selection screen for accepting selection of a setting target access point.
If the user selects an SSID on the connection destination selection screen, the CPU 103 acquires, in step S604, the version information of the OS using the Application Program Interface (API) of the OS. In step S605, the CPU 103 determines whether the acquired OS version is an OS version supporting the password copy function. In this embodiment, as an example, assume that iOS 16(a predetermined version) or higher supports the password copy function. The password copy function indicates a function of selecting a desired SSID on the system screen of the OS which is a screen for executing the Wi-Fi setting function of iOS, and copying the password. A password having undergone a copy operation is saved in a clipboard as a save area for temporarily saving data. Note that the system screen of the OS is a screen displayed by the system setting application of OS standard. The system setting application of OS standard is an application having a function of controlling wireless connection between the information processing apparatus 101 and another apparatus. More specifically, the system setting application of OS standard has a function of establishing Wi-Fi connection between the information processing apparatus 101 and the access point and a function of managing various kinds of information concerning the Wi-Fi connection between the information processing apparatus 101 and the access point. The various kinds of information concerning the Wi-Fi connection include, for example, the SSID, password, encryption method, authentication method, and the like of the access point to which the information processing apparatus 101 is connected by Wi-Fi. In this embodiment, the system setting application of OS standard can display various kinds of information concerning the Wi-Fi connection by accepting an operation from the user. The information processing apparatus 101 including an OS that supports the password copy function and whose version is equal to or higher than the predetermined version can copy the password displayed, as described above, on the system screen of the OS and save the password in the clipboard. However, the information processing apparatus 101 including an OS that does not support the password copy function and whose version is lower than the predetermined version cannot copy the password displayed, as described above, on the system screen of the OS and save the password in the clipboard. Therefore, if it is determined in step S605 that the OS version is not a version supporting the password copy function, the CPU 103 advances to step S612, and displays a password input screen on the display unit 108.
If it is determined in step S605 that the OS version is a version supporting the password copy function, the process advances to step S606. In step S606, the CPU 103 acquires, using the API of the OS, the state of the clipboard as an area that temporarily saves the data when a copy operation is performed on the information processing apparatus 101. That is, state acquisition processing of acquiring the state of the clipboard before displaying a guidance screen to the user is performed.
In step S607, the CPU 103 displays the guidance screen for prompting the user to use the password copy function.
In step S608, the CPU 103 causes the process to branch in accordance with the user operation accepted on the guidance screen. That is, if the pressing of the OK button 502 is accepted on the guidance screen, the process advances to step S609. If the pressing of the cancel button 503 is accepted on the guidance screen, the process advances to step S612, and the CPU 103 displays the password input screen shown in
In step S609, the CPU 103 acquires the information in the clipboard using the API of the OS. That is, state acquisition processing of acquiring the state of the clipboard after displaying the guidance screen to the user is performed. In step S610, the CPU 103 determines whether there is a difference between the clipboard information acquired in step S606 and that acquired in step S609. If it is determined that there is a difference, the process advances to step S611. On the other hand, if it is determined that there is no difference, the processes from step S607 are repeated.
As described above, according to this embodiment, if the information saved in the clipboard changes, it is determined that the user executes the password copy function in accordance with the guidance. Therefore, the processes of steps S606 to S610 can indicate processing for determining whether the password copy function is executed.
If the process advances from step S610 to step S611, the CPU 103 acquires, from the clipboard, the password information copied by the user by the operation displayed on the guidance screen, and transmits the password information as connection setting information of the network setup to the communication apparatus 151. The connection setting information is transmitted using, for example, SNMP and MIB.
As described above, according to this embodiment, it is possible to prevent the user from erroneously inputting a password. In addition, for example, the user need not go to see a password or the like attached to the back surface of a router or the like. As a result, it is possible to improve convenience in a network setup.
The second embodiment will be described below concerning points different from the first embodiment. In this embodiment, as an example of a network setup, when a network setup in an information processing apparatus 101 fails, the user is prompted again to perform a setup (reconnection setting) using a password copy function.
After connection setting information is transmitted to a communication apparatus 151 in step S611, the CPU 103 returns connection to an access point 131 in step S701. In step S702, the CPU 103 performs search processing of the communication apparatus 151 in the network of the access point 131. The search processing is performed using, for example, SNMP and MIB. For example, the information processing apparatus 101 transmits a search packet onto the network of the access point 131 by broadcast, and confirms, for a predetermined time, whether a response is returned. Note that the example of using SNMP and MIB has been explained but another communication protocol and another data format may be used.
In step S703, the CPU 103 determines whether the communication apparatus 151 is detected. If it is determined that the communication apparatus 151 is detected, the processing shown in
As described above, according to this embodiment, even if, as a result of a network setup, connection to an access point corresponding to a selected SSID has failed and the user is prompted to perform reconnection setting processing, it is possible to prompt the user to perform a setup again using the password copy function of the OS. This can prevent the user from erroneously inputting the password, and improve convenience in a network setup.
Embodiment(s) of the present invention can also be realized by a computer of a system or apparatus that reads out and executes computer executable instructions (e.g., one or more programs) recorded on a storage medium (which may also be referred to more fully as a ‘non-transitory computer-readable storage medium’) to perform the functions of one or more of the above-described embodiment(s) and/or that includes one or more circuits (e.g., application specific integrated circuit (ASIC)) for performing the functions of one or more of the above-described embodiment(s), and by a method performed by the computer of the system or apparatus by, for example, reading out and executing the computer executable instructions from the storage medium to perform the functions of one or more of the above-described embodiment(s) and/or controlling the one or more circuits to perform the functions of one or more of the above-described embodiment(s). The computer may comprise one or more processors (e.g., central processing unit (CPU), micro processing unit (MPU)) and may include a network of separate computers or separate processors to read out and execute the computer executable instructions.
