[0002] With the widespread adoption of smart TVs, smart speakers, smart home control centers, and other smart terminal devices, users' demand for convenient human-computer interaction methods is increasing daily. Remote controls, as the primary input control device, widely employ Bluetooth Low Energy (BLE) technology to achieve wireless connectivity with display devices or other slave devices. BLE technology boasts advantages such as low power consumption, low cost, and stable connection, making it the mainstream wireless communication solution for remote control devices.

[0003] In real-world scenarios, users often have multiple Bluetooth-enabled slave devices in their homes (such as multiple smart TVs, projectors, and audio systems), while users typically only have one remote control.

Conventional Bluetooth pairing mechanisms rely on broadcasting, scanning, and automatic connection processes between devices. Users cannot actively specify the target device during the pairing phase, leading to pairing results that may not match the user's intentions, resulting in an unpredictable connection outcome.

[0018] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0020] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0021] In conventional technologies, users often have multiple Bluetooth-enabled slave devices in their homes (such as multiple smart TVs, projectors, and audio systems), while users typically only have one remote control. When this remote control enters pairing mode, it may be scanned and attempted to connect by multiple slave devices simultaneously. Conventional Bluetooth pairing mechanisms rely on broadcasting, scanning, and automatic connection processes between devices. Users cannot actively specify the target device during the pairing phase, leading to pairing results that may not match the user's intentions, resulting in unpredictable connection outcomes.

[0022] This application provides a solution where an electronic device sends a Bluetooth scan request to a remote control to be connected. The remote control responds to the Bluetooth scan request by generating a Bluetooth scan response carrying a pairing identifier associated with the electronic device and sending it to the electronic device. The electronic device then outputs remote control button indication information corresponding to the pairing identifier, guiding the user to actively trigger a specific button to complete pairing. The electronic device then sends a Bluetooth connection request to the remote control, which only responds when the target button indicated by the triggered button indication information is pressed, thus achieving a Bluetooth connection between the electronic device and the remote control. This solution explicitly maps the user's operational intent to the device, avoiding misconnections caused by differences in signal strength and response timing during conventional pairing processes, significantly improving the accuracy and predictability of Bluetooth pairing.

[0023] Reference Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the Bluetooth connection method of this application.

[0024] It should be noted that the Bluetooth connection method is applied to electronic devices with Bluetooth communication capabilities. In a Bluetooth connection, the electronic device can act as the connection initiator (master device) or the responder (slave device), specifically including devices such as televisions, stereos, air conditioners, computers, mobile phones, and tablets. This embodiment does not impose any limitations on this. The Bluetooth connection method includes: Step A10: Send a Bluetooth scan request to the remote control; In one feasible embodiment, the electronic device can enable Bluetooth functionality by enabling the Bluetooth module and send a Bluetooth scan request to the remote control.

[0025] A Bluetooth scan request, or SCAN_REQ (Scan Request), is a control message in the Bluetooth Low Energy (BLE) protocol designed to obtain more device information.

[0026] A remote control can be a standalone physical device with multiple universal function buttons, or it can be a device that sends control commands by adding corresponding hardware and software modules to existing devices (such as mobile phones, watches, headphones, power banks, tablets, etc.).

[0027] For example, by adding corresponding software and hardware modules to a mobile phone, virtual buttons are generated in the mobile phone and become the remote control in the embodiments of this application.

[0028] Optionally, the buttons on the remote control can be either virtual buttons or physical buttons.

[0029] Optionally, the electronic device can send a Bluetooth scan request to one or more remote controls.

[0030] Step A20: Determine the pairing identifier associated with this device based on the received Bluetooth scan response sent by the remote control, wherein the Bluetooth scan response is generated by the remote control in response to the Bluetooth scan request; In one feasible embodiment, the remote controller can respond to a received Bluetooth scan request, generate a corresponding Bluetooth scan response, and send it back to the electronic device. The Bluetooth scan response generated by the remote controller encapsulates a pairing identifier, which is associated with the electronic device. The electronic device can then determine that the remote controller is the one that generated the pairing identifier based on the received Bluetooth scan response sent by the remote controller.

[0031] Bluetooth scan response refers to SCAN_RSP (Scan Response), a data packet in the BLE protocol. It is a reply from the broadcast device (i.e., remote control) to the scan device (i.e., electronic device) to the SCAN_REQ sent by the scanning device, and is used to return additional broadcast information.

[0032] The pairing identifier can be an ID (Identifier), which is a number or code assigned by the remote control to uniquely distinguish each electronic device in a multi-device environment, thereby guiding the user to confirm the pairing intention through button operation.

[0033] Optionally, a pairing identifier can be associated with an electronic device and a remote control. The pairing identifier clearly identifies the remote control that generated the pairing identifier and the electronic device that receives it.

[0034] Optionally, the electronic device may receive Bluetooth scan responses from one or more remote controls and other Bluetooth devices. If multiple remote controls capable of executing the Bluetooth connection method of this application exist in the current environment, the electronic device may receive multiple Bluetooth scan responses and determine the pairing identifier associated with each remote control.

[0035] Step A30: Output the remote control button indication information corresponding to the pairing identifier; In one feasible embodiment, after determining the pairing identifier assigned to it by the remote control, the electronic device determines the remote control button indication information corresponding to the pairing identifier and outputs the remote control button indication information, thereby guiding the user to actively trigger a specific button to complete the Bluetooth pairing between the remote control and the electronic device.

[0036] Remote control button indication information is a type of human-computer interaction prompt information. Its content is determined by the pairing identifier and is used to guide the user to confirm the pairing intention by triggering the physical button on the remote control that has the same identifier value.

[0037] Optionally, the electronic device can determine the remote control button indication information corresponding to the pairing identifier associated with it based on the preset mapping relationship between the pairing identifier and the remote control button indication information.

[0038] Optionally, the remote control button indication information can be the indication information of a single button, such as pressing the number 1 key, pressing the OK key, etc., or it can be the indication information of a combination of multiple buttons, such as pressing the OK key and the number 1 key at the same time, or pressing the OK key first and then pressing the number 1 key, etc. The embodiments of this application do not limit this.

[0039] Alternatively, the electronic device can output remote control button indication information in the form of audio, images, indicator lights, etc.

[0040] Optionally, the electronic device can receive Bluetooth scan responses from one or more remote controls and other Bluetooth devices. If there are multiple remote controls in the current environment capable of executing the Bluetooth connection method of this application, the electronic device can receive multiple Bluetooth scan responses, determine the pairing identifier associated with each remote control, and then output remote control button indication information corresponding to at least some of the pairing identifiers.

[0041] Optionally, when the electronic device determines the pairing identifiers generated by multiple remote controllers, it can simultaneously output the remote controller button indication information corresponding to the pairing identifiers associated with the multiple remote controllers; the electronic device can also filter out at least one target identifier from the multiple pairing identifiers and output the remote controller button indication information corresponding to the target identifier.

[0042] Step A40: Send a Bluetooth connection request to the remote control; In one feasible embodiment, the electronic device sends a Bluetooth connection request to the remote control.

[0043] The Bluetooth connection request, or CONNECT_REQ (Connection Request), is a key control message in the Bluetooth Low Energy protocol used to initiate and establish a point-to-point communication connection between two devices.

[0044] Optionally, the electronic device can send a Bluetooth connection request to the remote control associated with the pairing identifier corresponding to the remote control button indication information it outputs, that is, send a targeted Bluetooth connection request; the electronic device can also send a Bluetooth connection request to all connectable devices in the current environment, but only the remote control that triggered the target button can respond to the request, thereby ensuring the accuracy and predictability of Bluetooth pairing.

[0045] Step A50: Upon receiving a Bluetooth connection response sent by the remote control in response to the Bluetooth connection request, a Bluetooth connection is established with the remote control. The Bluetooth connection response is generated by triggering the target button on the remote control, and the target button is the button indicated by the button indication information on the remote control.

[0046] In one embodiment, if the remote control triggers the target button, it will respond to the Bluetooth connection request sent by the electronic device associated with the pairing identifier corresponding to the target button, generate a Bluetooth connection response, and send the Bluetooth connection response back to the electronic device; and the electronic device will establish a Bluetooth connection with the remote control when it receives the Bluetooth connection response sent by the remote control in response to the Bluetooth connection request.

[0047] For example, refer to Figure 2 In the current scenario, there are multiple electronic devices 102 that support Bluetooth pairing. To establish a Bluetooth connection with the target device, the remote control 101, upon receiving a Bluetooth scan request from an electronic device 102, generates a pairing identifier (ID) uniquely associated with each electronic device 102 and encapsulates it in a Bluetooth scan response, sending it to each electronic device 102. Upon receiving the Bluetooth scan response, each electronic device 102 can determine the specific pairing identifier (ID) assigned to it by the remote control 101, such as... Figure 2 Device A has ID 1, Device B has ID 2, and Device C has ID 3. Each electronic device 102 outputs remote control button indication information corresponding to its associated pairing identifier. For example, Device A displays "Trigger remote control button 1," Device B displays "Trigger remote control button 2," and Device C displays "Trigger remote control button 3," thus guiding the user to confirm the pairing intention through button operations on remote control 101. For example, Device A, Device B, and Device C all send Bluetooth connection requests to remote control 101. If the user presses button 1 on remote control 101, remote control 101 responds to the Bluetooth connection request sent by Device A, generates a Bluetooth connection response, and sends it back to Device A, thereby establishing a Bluetooth connection with Device A and significantly improving the accuracy and predictability of Bluetooth pairing.

[0048] In this embodiment, the electronic device sends a Bluetooth scan request to the remote control to be connected. The remote control responds to the Bluetooth scan request by generating a Bluetooth scan response carrying a pairing identifier associated with the electronic device and sending it to the electronic device. The electronic device then outputs remote control button indication information corresponding to the pairing identifier, guiding the user to actively trigger a specific button to complete pairing. The electronic device then sends a Bluetooth connection request to the remote control. The remote control will only respond when the target button indicated by the triggered button indication information is pressed, thereby achieving a Bluetooth connection between the electronic device and the remote control. Through the above-described scheme of this application embodiment, the user's operational intent is clearly mapped to the device, avoiding misconnections caused by differences in signal strength and response timing during conventional pairing processes, significantly improving the accuracy and predictability of Bluetooth pairing.

[0049] Based on the first embodiment described above, a second embodiment of the Bluetooth connection method of this application is proposed. In this embodiment, step A10, the step of sending a Bluetooth scanning request to the remote control, includes: Step A11: Enable Bluetooth scanning function; In one feasible embodiment, the electronic device enables Bluetooth scanning to begin listening to broadcast channels in order to receive broadcast packets.

[0050] Step A12: If a scannable broadcast packet is detected, a Bluetooth scan request is sent to the remote control that sent the scannable broadcast packet, wherein the scannable broadcast packet is generated by triggering the Bluetooth pairing button on the remote control.

[0051] In one feasible embodiment, when a user triggers the Bluetooth pairing button on the remote control, the remote control will send a scannable broadcast packet, and when the electronic device detects the scannable broadcast packet, it will send a Bluetooth scan request to the remote control.

[0052] Scannable broadcast packets can be ADV_IND (Advertising - Connectable and Scannable Undirected Event), which allows other devices to discover, obtain information, and establish connections.

[0053] The Bluetooth pairing button is a physical or virtual button on the remote control. When the user presses it, the remote control enters a discoverable pairing mode and begins sending scannable broadcast packets so that host devices such as TVs and set-top boxes can discover it and establish a Bluetooth connection with it.

[0054] In one feasible implementation, step A30, the step of outputting the remote control button indication information corresponding to the pairing identifier, includes: Step A31: Determine the device identification information of the remote control based on the Bluetooth scan response; Step A32: If the device identification information meets the preset identification conditions, output the remote control button indication information corresponding to the pairing identifier.

[0055] In one feasible embodiment, the electronic device determines the device identification information of the remote control based on the information carried in the Bluetooth scan response, and then determines whether the device identification information of the remote control meets preset identification conditions. If the device identification information of the remote control meets the preset identification conditions, it indicates that the remote control may belong to the remote control that the user wants to connect to, and then outputs the remote control button indication information corresponding to the pairing identifier. For remote controls or other devices whose device identification information does not meet the identification conditions, the electronic device does not output the remote control button indication information corresponding to their pairing identifier. Through the above scheme, this application embodiment automatically blocks irrelevant devices, avoids mispairing, reduces invalid connection attempts, and improves connection accuracy and resource utilization.

[0056] Device identification information refers to a set of characteristic parameters obtained by an electronic device during the Bluetooth pairing process by parsing the Bluetooth scan response (SCAN_RSP) and related broadcast data sent by the remote control. This comprehensive set of information is used to uniquely identify, classify, filter, and confirm the identity of the target remote control.

[0057] In this embodiment, the scanned devices are filtered by pre-set identification conditions. The pairing guidance process is triggered only when the device identification information matches, and the corresponding remote control button operation prompts are displayed, thereby realizing an automated and user-friendly Bluetooth pairing experience and effectively improving pairing efficiency and system intelligence.

[0058] In one feasible implementation, the device identification information includes: an identity identifier; the identification conditions include: the identity identifier meets preset identifier matching conditions; and step A32, the step of outputting the remote control button indication information corresponding to the paired identifier, includes: Step A321: If the identity identifier meets the identifier matching conditions, output the remote control button indication information corresponding to the paired identifier.

[0059] In one feasible embodiment, the electronic device can determine the remote control's identity from the Bluetooth scan response, such as the device name and device ID number, and determine whether the remote control's identity meets the identity matching conditions. If it does, the electronic device outputs the remote control button indication information corresponding to the pairing identity. If it does not meet the conditions, the electronic device does not output any information about the remote control.

[0060] Optionally, the identifier matching condition can be that the identifier contains specific keywords, or that the identifier contains specific prefixes, etc.

[0061] In this embodiment, the scanned devices are filtered by pre-set identification matching conditions. The pairing guidance process is triggered only when the remote control identification matches, and the corresponding remote control button operation prompts are displayed. This achieves an automated and user-friendly Bluetooth pairing experience, effectively improving pairing efficiency and system intelligence.

[0062] In one feasible implementation, the device identification information includes: signal strength; the identification condition includes: the signal strength is greater than a preset strength threshold; step A32, the step of outputting the remote control button indication information corresponding to the pairing identifier, includes: Step A322: If the signal strength is greater than the strength threshold, output the remote control button indication information corresponding to the pairing identifier.

[0063] In one feasible embodiment, the electronic device can determine the signal strength of the remote control from the Bluetooth scan response. Since the signal strength of the Bluetooth signal reflects the physical distance between the remote control and the electronic device, it can be determined whether the signal strength of the remote control is greater than a preset strength threshold. If it is greater, the remote control button indication information corresponding to the pairing identifier is output. If it is less than or equal to the threshold, no information about the remote control is output.

[0064] Optionally, the device identification information includes: identity identifier and signal strength. The identification conditions include: the identity identifier meets the preset identifier matching conditions and the signal strength is greater than the preset strength threshold. Therefore, when the remote control's identity identifier meets the identifier matching conditions and the remote control's signal strength is greater than the preset strength threshold, the remote control button indication information corresponding to the pairing identifier is output.

[0065] In this embodiment, the scanned devices are filtered by pre-set identification matching conditions. The pairing guidance process is triggered only when the remote control identification matches, and the corresponding remote control button operation prompts are displayed. This achieves an automated and user-friendly Bluetooth pairing experience, effectively improving pairing efficiency and system intelligence.

[0066] In one feasible implementation, step A32, the step of outputting the remote control button indication information corresponding to the pairing identifier, includes: Step A323: Display the remote control button indication information corresponding to the pairing identifier on the associated display screen.

[0067] In one feasible embodiment, if the electronic device has an associated display screen, the remote control button indication information corresponding to the pairing identifier can be displayed on the display screen.

[0068] And / or, in step A324, play the remote control button indication information corresponding to the pairing identifier through the associated audio playback device.

[0069] In one feasible embodiment, if the electronic device has an associated audio playback device, the remote control button indication information corresponding to the pairing identifier can be played through the audio playback device.

[0070] Optionally, if the electronic device has an associated audio playback device and a display screen, the remote control button indication information corresponding to the pairing identifier can be displayed on the display screen, and the remote control button indication information corresponding to the pairing identifier can be played through the audio playback device. Alternatively, at least one of these methods can be selected to output button indication information.

[0071] In this embodiment, the remote control button indication information corresponding to the pairing identifier is displayed and / or played by the electronic device, thereby guiding the user to actively trigger a specific button to complete the pairing, which significantly improves the accuracy and predictability of Bluetooth pairing.

[0072] To aid in understanding the above technical solutions, this application provides a more complete embodiment, using a television as the executing entity to perform the Bluetooth connection method of this application embodiment, referring to... Figure 3 : Step A101: The TV enables Bluetooth and begins Bluetooth scanning; if a scannable broadcast packet is detected, the TV sends a Bluetooth scan request to the remote control that sent the scannable broadcast packet; upon receiving the Bluetooth scan response from the remote control, the TV determines the remote control's device identification information, including: identity identifier and signal strength.

[0073] In step A102, the TV determines whether the remote control's identity meets the preset identity matching conditions. If yes, it proceeds to step A103; otherwise, it re-executes step A101 to perform a Bluetooth scan.

[0074] In step A103, the TV determines whether the signal strength of the remote control meets the condition, that is, whether the signal strength is greater than the preset strength threshold. If yes, then step A104 is executed; otherwise, step A101 is executed again to perform Bluetooth scanning.

[0075] In step A104, the TV displays the remote control button indication information corresponding to the pairing identifier on the screen.

[0076] Step A105: The TV sends a Bluetooth connection request to the remote control.

[0077] Step A106: After the TV sends the Bluetooth connection request, it determines whether the Bluetooth connection with the remote control is successful. If yes, the Bluetooth connection with the remote control is completed. If no, step A101 is repeated to perform Bluetooth scanning.

[0078] Based on any of the above embodiments, a third embodiment of the Bluetooth connection method of this application is proposed. In this embodiment, the Bluetooth connection method uses a remote control. The remote control can be a standalone physical device with multiple general-purpose function buttons, or it can be a device that sends control commands by adding corresponding software and hardware modules to an existing device (e.g., mobile phone, watch, earphone, power bank, tablet, etc.). The buttons on the remote control can be virtual buttons or physical buttons. The Bluetooth connection method includes: Step B10: In response to a Bluetooth scan request sent by an electronic device, a Bluetooth scan response is generated, wherein the Bluetooth scan response encapsulates a pairing identifier associated with the electronic device. In one feasible embodiment, after the remote control is powered on and Bluetooth is enabled, it can respond to the Bluetooth scanning request sent by the electronic device, generate a pairing identifier associated with the electronic device, and encapsulate it in the Bluetooth scanning response.

[0079] In one feasible implementation, before step B10, which generates a Bluetooth scanning response in response to a Bluetooth scanning request sent by an electronic device, the method further includes: after the remote control is powered on, dynamically detecting whether its preset Bluetooth pairing key is triggered; when the remote control detects that its Bluetooth pairing key is triggered, sending a scannable broadcast packet, wherein the scannable broadcast packet is used to send a Bluetooth scanning request to the remote control when the electronic device scans the scannable broadcast packet.

[0080] The Bluetooth pairing button is a physical or virtual button on the remote control. When the user presses it, the remote control enters a discoverable pairing mode and begins sending scannable broadcast packets so that host devices such as TVs and set-top boxes can discover it and establish a Bluetooth connection with it.

[0081] For example, the Bluetooth pairing button is the "voice button" on the remote control.

[0082] Optionally, the remote control can poll the buttons to detect whether its preset Bluetooth pairing button has been triggered.

[0083] Optionally, when the remote control detects that its Bluetooth pairing button has been triggered, it can first determine whether there is a device waiting to be reconnected. A device waiting to be reconnected refers to a device that has been successfully paired and bound before. If it exists, the remote control will try to connect to the device waiting to be reconnected first. If it does not exist, the remote control will enter the "discoverable" broadcast mode, send a scannable broadcast packet, and wait for a new pairing.

[0084] In one feasible implementation, step B10, the step of generating a Bluetooth scan response in response to a Bluetooth scan request sent by an electronic device, includes: Step B11: Generate a pairing identifier associated with the device address based on the device address of the electronic device that sent the Bluetooth scanning request; Step B12: Generate a Bluetooth scan response encapsulated with a pairing identifier.

[0085] In one feasible embodiment, the remote controller determines the device address of the electronic device that sent the Bluetooth scan request based on the received Bluetooth scan request, generates an associated pairing identifier for the device address, encapsulates the pairing identifier into the Bluetooth scan response, and then sends the Bluetooth scan response to the electronic device corresponding to the device address.

[0086] The device address can be a MAC address (Media Access Control Address).

[0087] The pairing identifier can be an ID (Identifier), which is a number or code assigned by the remote control to uniquely distinguish each electronic device in a multi-device environment, thereby guiding the user to confirm the pairing intention through button operation.

[0088] Optionally, the pairing identifier can be a unique identifier, meaning that remote controls for electronic devices with different device addresses can assign different pairing identifiers to them.

[0089] Optionally, the step of the remote controller generating a pairing identifier associated with the device address includes: determining whether there is an associated pairing identifier for the device address; if there is, reusing the original identifier; if there is not, selecting an unused identifier from a preset value range as the pairing identifier.

[0090] In this embodiment, the remote control will generate a corresponding pairing identifier based on the device address of the electronic device, so that different electronic devices correspond to different pairing identifiers, ensuring the uniqueness and certainty of the pairing identifier, improving the security of the pairing process, and thus supporting users to select target devices for Bluetooth pairing based on button operations in a multi-device environment.

[0091] Step B20: Send a Bluetooth scan response to the electronic device so that the electronic device outputs remote control button indication information corresponding to the pairing identifier; In one feasible embodiment, the remote controller sends a Bluetooth scan response to the electronic device, causing the electronic device to output remote control button indication information corresponding to the pairing identifier. For example, the electronic device displays the remote control button indication information corresponding to the pairing identifier on an associated display screen, or plays the remote control button indication information corresponding to the pairing identifier through an associated audio playback device.

[0092] Step B30: In response to the key trigger operation, determine the target identifier corresponding to the triggered key from the pairing identifiers; In one feasible embodiment, the remote control responds to a button triggering operation by determining the target identifier corresponding to the triggered button from the pairing identifiers it generates for each electronic device, thereby explicitly mapping the user's operation intent onto the device.

[0093] Step B40: In response to the Bluetooth connection request sent by the target device associated with the target identifier, generate a Bluetooth connection response and send it to the target device to establish a Bluetooth connection with the target device.

[0094] In one feasible embodiment, the remote controller responds to a Bluetooth connection request sent by a target device associated with a target identifier, generates a Bluetooth connection response, and sends it to the target device, thereby establishing a Bluetooth connection with the target device.

[0095] For example, when a user presses button 1 on a remote control, the remote control determines that the target identifier corresponding to button 1 is ID: 1, and the electronic device associated with this target identifier is device 1. Therefore, the remote control will respond to the Bluetooth connection request of device 1, but will not respond to the Bluetooth connection requests of other devices.

[0096] In this embodiment, the electronic device sends a Bluetooth scan request to the remote control to be connected. The remote control responds to the Bluetooth scan request by generating a Bluetooth scan response carrying a pairing identifier associated with the electronic device and sending it to the electronic device. The electronic device then outputs remote control button indication information corresponding to the pairing identifier, guiding the user to actively trigger a specific button to complete pairing. The electronic device then sends a Bluetooth connection request to the remote control. The remote control will only respond when the target button indicated by the triggered button indication information is pressed, thereby achieving a Bluetooth connection between the electronic device and the remote control. Through the above-described scheme of this application embodiment, the user's operational intent is clearly mapped to the device, avoiding misconnections caused by differences in signal strength and response timing during conventional pairing processes, significantly improving the accuracy and predictability of Bluetooth pairing.

[0097] To aid in understanding the above technical solutions, this application provides a more complete embodiment, using a television as the executing entity to perform the Bluetooth connection method of this application embodiment. The target device to be connected to the television is a Bluetooth speaker. (Refer to...) Figure 4 : Step B101: Power on the remote control.

[0098] Step B102: The remote control performs button polling.

[0099] In step B103, the remote control checks whether the Bluetooth pairing button has been triggered. If yes, proceed to step B104; otherwise, proceed to step B102.

[0100] In step B104, the remote control determines whether there is a device to be reconnected. If yes, proceed to step B105; otherwise, proceed to step B106.

[0101] Step B105: The remote control reconnects to the device to be reconnected via Bluetooth.

[0102] Step B106: The remote control sends a scannable broadcast packet.

[0103] In step B107, the remote controller receives a Bluetooth scan request sent by the electronic device based on a scannable broadcast packet, generates a pairing identifier and a Bluetooth scan response according to the device address of the electronic device, and sends them to the electronic device.

[0104] In step B108, the remote control receives a Bluetooth connection request from the electronic device. In response to the button trigger operation, the remote control determines the target identifier corresponding to the triggered button from the pairing identifier; then it determines the target device associated with the target identifier, and responds to the Bluetooth connection request of the target device by sending a Bluetooth connection response to the target device.

[0105] In step B109, the remote control determines whether the Bluetooth connection with the target device is successful. If yes, the Bluetooth connection with the target device is completed. If not, step B102 is executed again to perform a new round of Bluetooth pairing.
