Referring to
The first communication unit 110 may be implemented as an optical receiving module for receiving an infra-red (IR) signal. The first communication unit 110 receives an optical signal, such as an IR signal, through an optical window (not shown). The IR signal received through the first communication unit 110 may be a signal for controlling the electronic device 100, or may be a signal for controlling another device that is received by IR sniffing.
The second communication unit 110-2 performs a function to perform Bluetooth communication, and can be implemented as a Bluetooth communication module. Accordingly, the second communication unit 110-2 may receive various types of Bluetooth packets according to the Bluetooth communication standard, for example, a direct advertising packet, an undirected advertising packet, or the like.
The processor 120 may perform an overall control operation of the electronic device 100.
The processor 120 according to an embodiment may be implemented with at least one of a digital signal processor (DSP), a microprocessor, and a time controller (TCON), a central processing unit (CPU), a micro controller unit (MCU), a micro processing unit (MPU), a controller, an application processor (AP), a communication processor (CP), and an advanced reduced instruction set computing (RISC) machine (ARM) processor or may be defined as a corresponding term. The processor may be implemented in a system on chip (SoC) type or a large scale integration (LSI) type in which a processing algorithm is built therein or in a field programmable gate array (FPGA) type.
The processor 120 may identify whether the IR signal received through the first communication unit 110 is a preset IR signal. Here, the preset IR signal may include a code for causing the second communication unit 110-2 to operate in a Bluetooth scan state.
If the first information included in the received IR signal matches the preset first information, the processor 120 can identify whether the preset second information is included in the received IR signal. Here, the second information may be information for controlling the second communication unit 110-2 to operate in a scan state.
For example, the processor 120 may identify whether the preset second information is included in the received IR signal only when the first information included in the received IR signal, that is, only when the manufacturer information is information about a specific manufacturer, and if the preset second information is included in the received IR signal, the processor 120 may control so that the second communication unit 110-2 operates in a scan state.
The reason why the processor 120 first identifies the first information in the received IR signal is that the IR signal received from the remote control device manufactured by another manufacturer can be ignored. If the manufacturer information is identified earlier than the second information controlling the scan state, the processing speed can be improved.
If a command to perform a scan operation to receive an undirected advertising packet is included in the received IR signal, the processor 120 may control to switch the state of the electronic device 100 or the state of the second communication unit 110-2 to the scan state. The scan state may be a state capable of receiving (or scanning or reading) the undirected advertising packet.
The processor 120 may control so that the second communication unit 110-2 operates in a scan state to receive the undirected advertising packet.
When the second communication unit 110-2 is in the scan state, if the undirected advertising packet is received from the remote control device 200, the processor 120 can obtain the identification information of the remote control device 200 and the identification information of the target device from the undirected advertising packet. Here, the identification information of the target device may be address information of the target device (or destination), for example, media access control (MAC) address information. Generally, a field for recording destination information is not defined in an undirected advertising packet according to a Bluetooth communication standard, but according to an embodiment, address information of a target device can be included in a field (e.g., a custom data field) assigned to each manufacturer and transmitted.
The target device is a device to try Bluetooth connection by the remote control device 200, and if the pairing between the remote control device 200 and the electronic device 100 is made, the remote control device 200 may include the identification information of the electronic device 100 in the undirected advertising packet and transmit the same.
The processor 120 may provide a user interface (UI) to guide Bluetooth connection with the remote control device 200 if the identification information of the target device obtained from the undirected advertising packet matches the identification information of the electronic device 100. That is, the processor 120 may identify that the corresponding remote control device 200 tries to connect a Bluetooth connection based on the identification information of the remote control device 200 obtained from the undirected advertising packet, and may provide a UI to guide a Bluetooth connection with the remote control device 200.
If the identification information of the target device does not match the identification information of the electronic device 100, it is not necessary to provide a guide for the Bluetooth connection. This is because the target device which the remote control device 200 wishes to make a Bluetooth connection is not the electronic device 100.
If the identification information of the target device included in the undirected advertising packet matches the identification information of the electronic device 100, the processor 120 can identify whether the identification information of the remote control device 200 included in the undirected advertising packet matches the identification information included in the Bluetooth pairing history of the electronic device 100. If it is identified that the identification information of the remote control device 200 matches the identification information included in the Bluetooth pairing history of the electronic device 100, the processor 120 can provide a first UI for guiding the Bluetooth connection with the remote control device 200. Here, the first UI for guiding the Bluetooth connection may include at least one of a UI guiding that the electronic device 100 is not connected to the remote control device 200, and a UI guiding user manipulation to retry the Bluetooth pairing. That is, the first UI may be provided if the identification information of the target device in the undirected advertising packet matches the identification information of the electronic device 100, and the identification information of the remote control device 200 matches the identification information included in the Bluetooth pairing history of the electronic device 100.
If the processor 120 identifies that the identification information of the remote control device 200 does not match the identification information included in the Bluetooth pairing history of the electronic device 100, the processor 120 can provide the second UI for guiding the Bluetooth connection. In this case, the second UI may include at least one of a UI guiding that the electronic device 100 is paired with another remote control device and a UI guiding user manipulation for Bluetooth pairing. That is, the second UI may be provided if the identification information of the target device in the undirected advertising packet matches the identification information of the electronic device 100, but the identification information of the remote control device 200 does not match the identification information included in the Bluetooth pairing history of the electronic device 100.
The processor 120 can provide a UI similar to the first UI even when there is no identification information in the pairing history of the electronic device 100. That the identification information of the electronic device 100 is included in the undirected advertising packet received from the remote control device 100 may be seen such that the remote control device 200 and the electronic device 100 are paired, but the pairing information stored in the electronic device 100 is deleted due to any reason. In this case, the processor 120 may provide at least one of a UI guiding that the electronic device 100 is not connected to the remote control device 200 and a UI guiding manipulation to retry the Bluetooth pairing.
The UI guiding a user's manipulation for Bluetooth connection may include, for example, a guide to press a and b buttons of the remote control device 200 at the same time. When the user presses a and b buttons, the electronic device 100 may perform an operation for Bluetooth connection or reconnection.
In some cases, the provided UI may include a content that Bluetooth pairing between the devices is unable. (As illustrated in the attached figures explaining UI) As described above, if the Bluetooth connection is not normally performed for reasons such as loss of pairing information after the Bluetooth pairing, or the like, a cause can be identified and the user can be guided with the cause, and the user can be guided with the operation content suitable for each situation.
The remote control device 200 according to
The first communication unit 210-1 may perform Bluetooth communication, and can be implemented as a Bluetooth communication module. Accordingly, the second communication unit 210-2 may transmit various types of Bluetooth packets according to the Bluetooth communication standard, for example, a directed advertising packet, an undirected advertising packet, or the like.
The second communication unit 210-2 may be implemented as an optical communication module that transmits an infra-red (IR) signal. The IR signal transmitted through the first communication unit 210 may be a signal for controlling the electronic device 100, or may be a signal for controlling another device received by IR sniffing.
The processor 220 may be implemented in a type similar to the processor 120 of the electronic device 100 described in
The processor 220 may identify whether the first communication unit 210-1 is Bluetooth-paired (or in Bluetooth pairing) when a user command is input. Here, the user command may be in the form of pressing any button provided in the remote control device 100, but is not limited thereto.
If it is identified that the first communication unit 210-1 is Bluetooth-paired with an external device, the processor 220 can identify whether the first communication unit 210-1 is Bluetooth-connected with the external device. If the first communication unit 210-1 is not Bluetooth-connected with the external device, the processor 220 can transmit the directed advertising packet including the identification information of the external device for the Bluetooth connection with the external device for a preset time. The directed advertising packet may refer to a packet to transmit specific information by specifying certain information. If Bluetooth connection with the external device is not made for a preset period of time, the processor 220 can transmit a preset IR signal to cause the external device to operate in a scan state capable of receiving the undirected advertising packet to the external device using the second communication unit 210-2 of the remote control device 200. Here, the preset IR signal may include a code for controlling a manufacturer code and a scan state.
The undirected advertising packet including the identification information of the external device may be broadcast through the first communication unit 210-1. The advertising refers to a process of informing information at a certain period or at a specific time between devices performing communication. The advertising packet refers to a data packet including its own information or peripheral information (routing information).
The identification information of the external device of the target device may be included in a field assigned to each manufacturer in the undirected advertising packet, for example, a field assigned to record custom data.
Referring to
In general, the undirected advertising packet does not include destination information, but the undirected advertising packet according to an embodiment may include destination information.
For example, the MAC address of the electronic device 100 may be included in the manufacturer allocation area (M1 to M6) of the undirected advertising packet. However, the embodiment is not limited thereto, and various reserve areas may be used.
According to various embodiments, a UI for Bluetooth connection may be provided as a speech through not only a display but also a speaker.
When a press manipulation of an arbitrary button is done in the remote control device 200, the remote control device 200 may identify whether the Bluetooth communication function is usable. The remote control device 200 may check whether the Bluetooth pairing is made.
If the Bluetooth pairing has been performed in the past, since the pairing information is stored in the remote control device 200, the remote control device 200 can check whether the Bluetooth pairing is paired using the stored pairing information in operation S405.
The remote control device 200 can check whether the Bluetooth connection is normally made using the Bluetooth pairing information in operation S410. If a Bluetooth connection is made, the user may control the electronic device 100 using the Bluetooth remote control device 200. However, if a Bluetooth connection is not made, the user cannot control the electronic device 100 using the remote control device 200.
In this case, in order to try Bluetooth connection, the remote control device 200 may transmit the directed advertising packet for a preset time t1 in operation S415. The directed advertising packet is a data packet in which a target is determined, and the remote control device 200 can assign a target of the directed advertising packet to the electronic device 100 using the pairing information stored in the remote control device 200. There may be pre-stored pairing information in the remote control device 200, and the pairing information may include an address value of a device in which there was a Bluetooth connection in the past. The remote control device 200 may transmit the directed advertising packet to the address value of the apparatus for a preset time t1. Here, the preset time may be preferably 7.5 seconds, which may be changed by manufacturer settings or user settings.
The remote control device 200 may transmit a preset IR signal to the electronic device 100 if the Bluetooth connection is not normally performed after a preset period of time has passed since the directed advertising packet is transmitted in operation S420. The IR signal may be a signal that controls the electronic device 100 to be in a scan state. The scan state may be a state capable of receiving (or reading) an undirected advertising packet or an undirected advertising packet. In order to receive the undirected advertising packet transmitted from the remote control device 200, the electronic device 100 must be in a scan state for receiving the electronic device 100.
The IR signal transmitted by the remote control device 200 may include manufacturer identification information and the information to control the scan state.
If the IR signal is received from the remote control device 200, the electronic device 100 may analyze the received IR signal to identify whether the manufacturer information of the remote control device 200 is the same as the manufacturer information of the electronic device 100 in operation S425. According to an embodiment, in order for the electronic device 100 to recognize the scan state control command in the IR signal received from the remote control device 200, there should be an appointment for a corresponding command between the electronic device 100 and the remote control device 100. Accordingly, after the manufacturer information is first confirmed, only if the manufacturer information matches, a subsequent operation can be performed.
When it is determined that manufacturer information matches, the electronic device 100 may determine whether the IR signal includes a command to control the scan state, that is, a corresponding code in operation S430.
If it is determined that a scan state control code is included in the IR signal received from the remote control device 200, the electronic device 100 can switch to the scan state to perform the scan operation. When the electronic device 100 is switched to a scan state, the electronic device 100 may receive an undirected advertising packet transmitted from the remote control device 200.
In operation S440, the remote control device 200 may transmit the undirected advertising packet for a preset time t2 after a preset period of time has elapsed since the IR signal is transmitted. Since an undirected advertising packet is transmitted without deciding a specific object, any device capable of scanning an undirected advertising packet may be able to receive any device. Here, t2 may preferably be 10 seconds, but this may be changed by the user's setting.
As the target is not fixed, the undirected advertising packet can be received in various devices. The electronic device 100 may receive the undirected advertising packet transmitted by the remote control device 200 in a scan state.
The electronic device 100 may analyze information included in the undirected advertising packet. The electronic device 100 may analyze identification information included in the undirected advertising packet received from the remote control device 200.
Specifically, the identification information included in the undirected advertising packet may be information related to pairing information. In general, identification information of the remote control device 200 may be included in an undirected advertising packet. In the embodiment, identification information about a target device (external device) included in the pairing information of the remote control device 200 may be additionally included in the undirected advertising packet.
Here, the identification information may be a MAC address. The identification information included in the undirected advertising packet may include both a MAC address indicating the remote control device 200 and a MAC address of an external device (target device) connected to the remote control device 200.
The electronic device 100 can determine whether the identification information (MAC address) of the external device (the target device) included in the undirected advertising packet received by the remote control device 200 and the prestored identification information (MAC address) of the electronic device 100 match with each other in operation S445.
If the identification information (MAC address) of the external device (target device) included in the undirected advertising packet and the identification information (MAC address) previously stored in the electronic device 100 do not match, the electronic device 100 can determine that Bluetooth connection is not necessary.
If the identification information (MAC address) of the external device (target device) included in the undirected advertising packet received by the remote control device 200 and the identification information (MAC address) prestored in the electronic device 100 match with each other, the electronic device 100 can determine that Bluetooth connection is necessary, and then may perform the following operations (S450, S455). Since the identification information (MAC address) of the electronic device 100 refers to the identification information of the electronic device 100, the identification information may be always stored in a memory of the electronic device 100 regardless of whether or not the pairing information is stored.
The electronic device 100 may analyze identification information of the remote control device 200 through operations S450 and S455.
The electronic device 100 may determine whether the pairing information is stored in the memory of the electronic device 100 in operation S450. The electronic device 100 can determine whether the pairing information itself is stored in the electronic device 100 itself before analyzing the information included in the undirected advertising packet received from the remote control device 200. The meaning that the pairing information itself is not stored may mean that no pairing history is stored. In a standpoint of the electronic device 100, this may mean a recognition that Bluetooth connection has never been performed. For example, although a Bluetooth connection is actually performed, the pairing information stored in the electronic device 100 may be damaged due to a damage of the memory or an unexpected error.
If the electronic device 100 identifies that the pairing information is not stored in the electronic device 100, the electronic device 100 can automatically perform Bluetooth pairing with the remote control device 200 that transmitted the undirected advertising packet and may provide the connection UI to the user in operation S451. In this case, the electronic device 100 does not need to compare the identification information (MAC address) of the remote control device 200 included in the undirected advertising packet. Since the electronic device 100 has already lost pairing information, there is no object to be compared with the identification information (MAC address) of the remote control device 200 included in the undirected advertising packet.
If it is determined that the pairing information is not stored in the electronic device 100, the electronic device 100 can automatically perform Bluetooth pairing with the remote control device 200. This is because it has already been determined in operation S445 that the identification information (MAC address) of the electronic device 100 is included in the undirected advertising packet received from the remote control device 200 in operation S445. The remote control device 200 has already identified the identification information (MAC address) of the electronic device 100, although there is no pairing information in the electronic device 100, the electronic device 100 can determine that the remote control device 200 is a target for which a Bluetooth connection is to be performed.
Thus, the electronic device 100 can automatically perform a pairing operation with the remote control device 200. The electronic device 100 may provide a guide UI for connection with the paired remote control device 200 for the Bluetooth connection to the user. Here, the UI may be a connection UI. The connection UI may include the content that the Bluetooth connection is unable currently, and may include content for guiding a specific operation for the Bluetooth reconnection to the user. A specific embodiment of the operation of providing the connection UI in operation S451 will be described later with reference to
If the electronic device 100 determines that the pairing information is stored in the electronic device 100, the electronic device 100 may determine whether the identification information (MAC address) with the remote control device 200 included in the undirected advertising packet matches in operation S455.
Specifically, by analyzing the undirected advertising packet received from the remote control device 200, identification information (MAC address) indicating identification information of the remote control device 200 may be obtained. Using pairing information stored in the electronic device 100, whether the identification information matches the identification information (MAC address) indicating the identification information of the remote control device 200 may be identified. The pairing information stored in the electronic device 100 may include information on a remote control device in which a Bluetooth connection was made. Accordingly, by analyzing the undirected advertising packet received from the remote control device 200, the identification information (MAC address) of the remote control device 200 may be obtained, and the obtained identification information (MAC address) of the remote control device 200 can be compared with the identification information (MAC address) of the remote control device included in the previously stored pairing information.
If the identification information (MAC address) of the remote control device 200 included in the undirected advertising packet and the identification information (MAC address) of the remote control device 200 stored in the electronic device 100 do not match, the electronic device 100 may provide the pairing UI in operation S456. The pairing UI may be a UI indicating that the pairing information of the remote control device 200 and the electronic device 100 trying to make Bluetooth connection does not match. A specific embodiment of the operation of providing the pairing UI in operation S456 will be described below with reference to
If the identification information (MAC address) of the remote control device 200 included in the undirected advertising packet and the identification information (MAC address) of the remote control device stored in the electronic device 100 match, the electronic device 100 can display the connection UI in operation S457. The connection UI may be the UI same as the connection UI displayed in step S451. A detailed embodiment of the operation of providing the connection UI in operation S457 will be described later with reference to
Referring to
Although the electronic device 100 has been described as providing only a connection UI and a pairing UI in
In operation S425, the electronic device 100 may check whether the manufacturer is identical based on the IR signal received from the remote control device 200. If a preset part representing the same manufacturer is included in the IR signal, the electronic device 100 can determine that the manufacturer of the remote control device 200 is identical. If the preset part representing the same manufacturer is not included in the IR signal, the electronic device 100 may provide a compatibility UI in operation S426. A point in time of providing the compatibility UI may be limited to a case where the electronic device 100 recognizes that the user has already tried Bluetooth connection. The electronic device 100 can receive various IR signals and if a specific UI is provided only for a reason that no manufacturer information is included in the IR signal, no other remote control device controlling the set-top box connected to the TV can be used. A specific embodiment of the operation to provide the compatibility UI in operation S426 will be described below with reference to
Therefore, a case where the operation S426 is performed can be limited to a case where the electronic device 100 is clearly aware that the user is trying Bluetooth connection. For example, the user may select a Bluetooth setting button or select a Bluetooth setting UI portion. The point in time may be when a signal related to a request for Bluetooth connection is received from the remote control device 200, or when the electronic device 100 internally recognizes that Bluetooth connection is not made. This point can be applied to all parts of providing the UI in describing the disclosure.
The compatibility UI may include the content that a manufacturer of the remote control device 200 currently used is not the same as the manufacturer of the electronic device 100, and may be difficult to be compatible. The user may easily recognize that a wrong remote control device 200 is used through the compatibility UI. The compatibility UI may include at least one of the content that the manufacturer is different, the compatibility is unable, or a signal is not recognizable.
The electronic device 100 can identify whether information related to the scan command is included in the IR signal received from the remote control device 200 in operation S430. If the information related to the scan command is included in the IR signal received from the remote control device 200 in operation S430, the electronic device 100 may perform a scan operation in the electronic device 100. Alternatively, the electronic device 100 may control the operation of the electronic device 100 to switch to a scan state. However, if the information related to the scan command is not included in the IR signal received from the remote control device 200 in operation S430, the electronic device 100 may provide the command UI in operation S431.
The command UI may be a UI informing the user that the signal corresponding to the scan command is not received in the IR signal received from the remote control device 200. The command UI may be a UI which is displayed when the IR signal includes information of being transmitted by the same manufacturer, but does not include a scan command. Specifically, the command UI may include that no scan command is included in the received IR signal. A specific embodiment of the operation of providing the command UI in operation S431 will be described below with reference to
The electronic device 100 can identify the identification information (MAC address) of the external device (target device) included in the undirected advertising packet and the identification information (MAC address) stored in the electronic device 100 itself in operation S445. If the identification information (MAC address) stored in the electronic device 100 and the identification information (MAC address) of the external device (target device) included in the undirected advertising packet do not match, the electronic device 100 can determine that the pairing information does not match.
Here, if the electronic device 100 identifies that the pairing information does not match, the electronic device 100 may display the pairing UI. The pairing UI may be a UI indicating that the pairing information does not match. It may be the same UI as the pairing UI provided in operation S456 of
The electronic device 100 can provide the pairing UI in a distinguished manner. For example, the pairing UI of the operation S446 and the operation S456 can be distinguished and displayed. A specific embodiment of the operation of providing the pairing UI in operation S446 will be described below with reference to
Meanwhile, the compatibility UI or command UI mentioned in
The electronic device 100 may be implemented by adding any one UI mentioned in
Referring to
In general, when an IR signal is transmitted from the remote control device 200, information capable of identifying a manufacturer can be included. Therefore, the IR signal transmitted from the LR1 will be different from the IR signal transmitted from the SR1. The electronic device 100 may identify whether the preset manufacturer information is included in the received IR signal, and if the preset manufacturer information is not included, the UI of the content that compatibility is not able may be displayed. Specifically, the UI of
A point in time of providing the compatibility UI can be limited when the electronic device 100 recognizes that the user has already tried Bluetooth connection. The electronic device 100 can receive various IR signals, and if a specific UI is provided for the reason that the manufacturer information is not included in the IR signal, the other remote control device which controls the set-top box connected to the TV cannot be used at all. A specific embodiment of the operation of providing a compatibility UI will be described in
A case when the operation S426 is performed can be limited to a case when the electronic device 100 can clearly know that the user tries Bluetooth connection. For example, a case where a user selects a Bluetooth setup button or select a Bluetooth setup UI part. Also, the case may be a point in time when a signal regarding Bluetooth connection request is received from the remote control device 200, or the point in time when the electronic device 100 may recognize that Bluetooth connection is unable. This can be applied to all parts which provide a UI in describing the disclosure.
The compatibility UI can include the content that the manufacturer of the remote control device 200 currently used is not the same as the manufacturer of the electronic device 100, so that it can be difficult to be compatible. The user can easily know that an incorrect remote control device 200 is used through the compatibility UI. The compatibility UI can include at least one of the content that the manufacturer is different, content that compatibility is unable, and the content that the signal cannot be recognized.
In the case of a Bluetooth remote control device, a power button can communicate using at least one of an IR method and a Bluetooth method. Other buttons can communicate using a Bluetooth method only. When a button other than a power button of the remote control device 200 is pressed in a state where the Bluetooth connection is not made, the remote control device 200 can generate a preset IR signal. The preset IR signal may include information about a control command to perform the scan operation by the electronic device 100. Therefore, when the user presses a button other than the power button of the remote control device 200, the remote control device 200 may generate an IR signal to perform the scan command.
When the user presses a power button of the remote control device 200, the remote control device 200 can generate an IR signal to turn off the electronic device 100. In this case, since the electronic device 100 receives the IR signal for the power off command that is not a scan command, the electronic device 100 can display the command UI of operation S431 and turn off the power of the electronic device 100.
The pairing UI may indicate two types. For convenience, the pairing UI may be divided into a first pairing UI and a second pairing UI. The pairing UI of
It is assumed that a user performs pairing with STV2 202, which is a new device, using the SR1 remote control device. In this case, the pairing information can be stored as (STV1-SR1) in STV1. However, the pairing information may be stored as (STV2-SR1) in SR1.
The identification information may not be identical when the SR1 transmits the undirected advertising packet to the STV1, because information about STV2, which is a new TV, is already stored in the SR1 remote control device, and the identification information (MAC address) included in the undirected advertising packet is also STV2. Accordingly, in STV1, it may be determined that the identification information (MAC address) of the electronic device does not match through the operation in S445. In addition, according to operation S446, the first pairing UI of
The same operation can be performed in the new device in addition to the device which has already been Bluetooth-paired with STV1 as SR1 described above. For example, assume that STV2 (electronic device, TV) and SR2 (remote controller, remote control device) are Bluetooth-paired. It is assumed that Bluetooth connection is tried to STV1 with the SR2 remote control device.
In the undirected advertising packet transmitted in the SR2, the information of STV2 may be included. Accordingly, STV1 may identify that the identification information of the electronic device does not match, and STV1 may provide the first pairing UI.
This is because it has been already determined in operation S445 that the identification information (MAC address) of the electronic device 100 is included in the undirected advertising packet received from SR1. As SR1 already has identified the MAC address of the electronic device 100, there is no pairing information in the electronic device 100, but the electronic device 100 can determine that SR1 is a target for Bluetooth connection.
Therefore, the electronic device 100 may automatically perform a pairing operation with SR1. The electronic device 100 may provide a user with a guide UI (connection UI,
It is assumed that a new Bluetooth pairing has been made between STV1 and SR2 202, which is a new remote control device. It is assumed that only one Bluetooth pairing information can be stored. If so, the prestored pairing information (STV1-SR1) can be deleted in STV1 and the pairing information (STV1-SR2) can be newly stored.
Since the newly generated Bluetooth pairing has occurred in STV1 and SR2, both STV1 and SR2 may include the pairing information (STV1-SR2). However, the SR1 can store the pairing information (STV1-SR1) as previously stored.
It is assumed that the SR1 remote control device tries Bluetooth connection with the STV1. The identification information stored in STV1 is (STV1-SR2), and the identification information received through the undirected advertising packet can be (STV1-SR1). Here, the identification information of the electronic device may match, but the identification information of the remote control device (the counterpart device) may not match. If the identification information (MAC address) of the remote control device does not match, STV1 may provide second pairing UI (
It is assumed that STV1 100 is Bluetooth paired with SR1 201, and STV1 stores Bluetooth pairing information (STV1-SR1). Similarly, it is assumed that SR1 stores Bluetooth pairing information (STV1-SR1).
It is assumed that the SR1 and other SR2 202 devices are Bluetooth paired with STV2. SR2 may include Bluetooth pairing information (SV2-SR2). SR1 and SR2 refer to the remote control device produced by the same manufacturer.
Assuming that there is a remote control device LR1 203 manufactured by the manufacturer different from SR1 and SR2, and it is assumed that the LTV1 (meaning TV manufactured by the manufacturer different from the STV1 is Bluetooth-paired. It is assumed that the LR1 stores the Bluetooth pairing information of (LTV1-LR1).
As assumed above, there are three remote control devices SR1, SR2, LR1 having different pairing information, and no remote control device is Bluetooth connected.
If the user uses SR1, all the identification information is the same, a connection UI (
If the user uses SR2, the identification information (MAC address) of the TV side does not match, the first pairing UI (
When a user uses LR1, the manufacturer identification information (IR signal) does not match, the compatibility UI (

The remote control device 200 may be composed of a Bluetooth low energy (BLE) processor and an IR receiver.
The BLE processor can identify a Bluetooth pairing and connection state with a TV (electronic device, external device, target device), and can determine whether an IR signal is transmitted or an undirected advertising packet is transmitted. In order to transmit the IR signal, the IR signal output command signal may be delivered to the IR signal output receiver, and the undirected advertising packet can be transmitted.
The IR transmitter may analyze the IR output command signal received from the BLE processor and transmit the IR signal.
The electronic device 100 may be composed of Micom, BLE application, BLE stack/module and UI controller.
The Micom may analyze the IR signal received from the remote control device 200 and determine whether to transmit the BLE application.
The BLE application can determine whether the BLE scan operation is performed by analyzing the IR value received from the Micom. In addition, the BLE application can analyze the undirected advertising packet received from the BLE stack to determine whether the re-pairing guide UI is required, and transmit a pop-up UI output signal to the UI control unit.
The BLE stack/module may receive the BLE scan command from the BLE application and perform a BLE scan operation. In addition, it is possible to transmit the undirected advertising packet received from the remote control device 200 to the BLE application.

The user can perform Bluetooth communication when pressing a button of the remote control device 200. However, if the Bluetooth connection is not properly established, the electronic device 100 cannot be controlled through the remote control device 200.
Accordingly, if the Bluetooth connection is not properly established, the Bluetooth connection may be tried by transmitting a specific signal to the remote control device 200.
Specifically, the BLE processor of the remote control device 200 may identify whether the electronic device 100 is paired. If the BLE processor of the remote control device 200 is paired with the electronic device 100, Bluetooth connection with the electronic device 100 can be determined.

The BLE processor of the remote control device 200 may transmit the IR transmit command signal to the IR transmitter after 7.5 seconds. The IR transmitter of the remote control apparatus 200 may transmit the IR signal after receiving the IR transmission command signal.
The BLE processor of the remote control device 200 may transmit the undirected advertising packet for ten seconds. Ten seconds can be set by a user's setting.
The Micom of the electronic device 100 can receive the IR signal from the IR transmitter of the remote control device 200 and determine whether to deliver a signal value to the BLE application (BLE APP). The Micom of the electronic device 100 can transmit the IR signal value to the BLE APP when the IR signal uses a preset IR format (Samsung IR format).

The BLE APP of the electronic device 100 can receive an undirected advertising packet from the BLE stack/module and compare the identification information (MAC address) stored in the memory of the electronic device 100 with the identification information of a target device (external device) included in the undirected advertising packet.
When the identification information (MAC address) stored in the memory of the electronic device 100 and the identification information of a target device (external device) included in an undirected advertising packet match, the electronic device 100 can compare identification information (MAC address) of the remote control device stored in the memory and identification information (MAC address) of the remote control device 200 included in the undirected advertising packet.
The BLE APP of the electronic device 100 may provide a pairing UI when the identification information (MAC address) of the remote control device stored in the memory of the electronic device 100 and the identification information (MAC address) of the remote control device 200 included in the undirected advertising packet do not match.

The BLE APP of the electronic device 100 may provide a connection UI when there is no address of the remote control device stored in the memory by the electronic device 100.
The electronic device 100 may implement a Bluetooth communication module and a module performing a general control operation separately. For example, in a Bluetooth communication module, an operation of determining whether or not a signal value is transferred to the BLE APP, an operation of determining whether a BLE scan is performed, and an operation of comparing MAC address can all be performed. A general processor may perform an operation of displaying a UI.
A controlling method of the electronic device 100 according to one embodiment may receive a preset IR from the remote control device in operation S1705. In addition, when the electronic device 100 receives a preset IR signal, the electronic device 100 controls to operate in a scan state capable of receiving an undirected advertising packet in operation S1715.
In addition, when an undirected advertising packet is received from the remote control device 200 in the scan state, the electronic device 100 may obtain the identification information of the target device from the undirected advertising packet in operation S1720.
If the identification information of the obtained target device is identified as matching the identification information of the electronic device 100, the electronic device 100 may provide a user experience interface (UI) for guiding a Bluetooth connection with the remote control device 200 in operation S1730.
In operation of S1730, if the obtained identification information of the target device matches the identification information of the electronic device 100, it may be identified that the identification information of the remote control device 200 included in the undirected advertising packet matches the identification information included in the Bluetooth pairing history and may provide the UI based on the identification.
In operation S1730, if the identification information of the remote control device 200 matches the identification information included in the Bluetooth pairing history, a UI for guising a user's manipulation to perform reconnection with the remote control device 200 can be provided.
In operation S1730, if the identification information of the remote control device 200 does not match the identification information included in the Bluetooth pairing history, a UI for guiding a user's manipulation to perform pairing with the remote control device 200 can be provided.
