[0049] In an embodiment of the present application, when a slave device is in a pairing state and fails to reconnect, the operating mode of the slave device is switched to master mode. At this time, the slave device sends a master device detection signal based on the master mode to detect a connectable master device, and then switches the operating mode to slave mode, thereby establishing a Bluetooth connection with the master device based on the slave mode. The slave device automatically completes the search for the master device and the pairing process with the master device through the master-slave mode switching. The above method can be used for the connection and pairing of all master and slave devices. It is simple and universal, reduces the user's learning cost, and improves the user experience.

[0050] based on Figure 1 The system architecture shown below will be combined with Figure 2-Figure 10 , the Bluetooth connection method provided in the embodiment of the present application is introduced in detail.

[0051] See Figure 2 , provides a flow chart of a Bluetooth connection method according to an embodiment of the present application. Figure 2 As shown, the embodiment of the present application describes the specific process of the Bluetooth connection method from both the slave device side and the master device side, and the method may include the following steps S101-S105.

[0052] S101, when the slave device determines that the slave device is in a pairing state and the backconnection fails, switching the working mode of the slave device to a master mode;

[0053] Specifically, the slave device works in slave mode by default, that is, before switching to master mode, the working mode of the slave device is slave mode. When the slave device enters the pairing state and fails to reconnect, the Bluetooth system working mode of the slave device is switched to master mode.

[0054] The pairable state refers to a state in which the Bluetooth of the slave device is turned on, is not currently connected to any device, and can be paired with other devices. The master mode refers to a working mode in which the slave device can detect and search for surrounding devices.

[0055] The reconnection failure may mean that there is no reconnectable device within the connectable range of the slave device, or that there is a reconnectable device within the connectable range but the reconnection fails. The reconnectable device refers to a device that has previously established a Bluetooth connection with the slave device and can be directly connected without re-pairing.

[0056] S102, the slave device sends a master device detection signal based on the master mode to detect a connectable master device;

[0057] Specifically, the master device detection signal is used to detect a connectable master device. When the slave device detects a connectable master device based on the master device detection signal, it obtains a connectable signal fed back by the master device. Based on the connectable signal, the slave device can determine the number of connectable master devices. The number may include one or more.

[0058] The master device detection signal carries the slave device identification information of the slave device, and the slave device identification can be the device number, device name, etc. of the slave device used for Bluetooth connection. The connectable signal carries information such as signal strength and master device identification, and the master device identification can be the device number, device name, etc. of the master device used for Bluetooth connection.

[0059] S103, the master device receives the master device detection signal;

[0060] S104, the slave device switches the working mode of the slave device to the slave mode;

[0061] Specifically, the slave mode refers to an operating mode in which the slave device can establish a Bluetooth connection with the master device.

[0062] S105: The master device establishes a Bluetooth connection with the slave device based on the master device detection signal.

[0063] Specifically, the master device detection signal carries the slave device identification information of the slave device, and the master device establishes a Bluetooth connection with the slave device based on the slave device identification. At this time, the slave device is in a slave mode.

[0064] In an embodiment of the present application, when the slave device is in a pairing state and fails to reconnect, the working mode of the slave device is switched to the master mode. At this time, the slave device sends a master device detection signal based on the master mode to detect a connectable master device. The master device receives the master device detection signal, and then switches the working mode of the slave device to the slave mode. The master device then establishes a Bluetooth connection with the slave device based on the master device detection signal. The slave device automatically completes the search for the master device and the pairing process with the master device through the master-slave mode switching. The above method can be used for the connection and pairing methods of all master-slave devices. It is simple and universal, reduces the user's learning cost, and improves the user experience.

[0065] See Figure 3 , provides a flow chart of a Bluetooth connection method according to an embodiment of the present application. Figure 3 As shown, the embodiment of the present application describes the specific process of the Bluetooth connection method from both the slave device side and the master device side, and the method may include the following steps S201-S213.

[0066] S201, when it is determined that the slave device is in a pairing state and the reconnection fails, switching the working mode of the slave device to a master mode;

[0067] Specifically, the slave device works in slave mode by default, that is, before switching to master mode, the working mode of the slave device is slave mode. When the slave device enters the pairing state and fails to reconnect, the Bluetooth system working mode of the slave device is switched to master mode.

[0068] The pairable state refers to the state in which the Bluetooth of the slave device is turned on and is not currently connected to any device, and can be paired with other master devices. The master mode refers to the working mode in which the slave device can detect and search for surrounding devices.

[0069] The reconnection failure may mean that there is no reconnectable device within the connectable range of the slave device, or that there is a reconnectable device within the connectable range but the reconnection fails. The reconnectable device refers to a device that has previously established a Bluetooth connection with the slave device and can be directly connected without re-pairing.

[0070] S202, sending a master device detection signal based on the master mode to detect a connectable master device;

[0071] Specifically, the slave device can send a master device detection signal based on the master mode to actively detect a connectable master device. When the slave device detects a connectable master device based on the master device detection signal, it will obtain a connectable signal fed back by the master device. Based on the connectable signal, the slave device can determine the number of connectable master devices. The number of master devices may include one or more. The connectable signal carries information such as signal strength and master device identification. The master device identification can be an identification for Bluetooth connection, such as the device number and device name of the master device.

[0072] Please also see Figure 4 , is an example diagram of a device detection provided in an embodiment of the present application. Figure 4 As shown, taking the slave device being a desktop microphone and the master device being a smart touch panel as an example, the working mode of the slave device is switched from slave mode to master mode, a master device detection signal is sent based on the master mode, the master device is detected, and a connectable signal fed back by the master device is obtained.

[0073] S203, receiving a detection signal from the master device;

[0074] Specifically, the master device receives a master device detection signal and feeds back a connectable signal. The master device detection signal carries the slave device identifier of the slave device, which can be an identifier for Bluetooth connection, such as the device number or device name of the slave device. The connectable signal carries information such as signal strength and the master device identifier, which can be an identifier for Bluetooth connection, such as the device number or device name of the master device.

[0075] S204, switching the working mode of the slave device to slave mode;

[0076] Specifically, the slave mode refers to an operating mode in which the slave device can establish a Bluetooth connection with the master device.

[0077] S205, sending a Bluetooth connection request to the slave device based on the master device detection signal;

[0078] Specifically, when the master device receives a master device detection signal, the master device sends a Bluetooth connection request to the slave device based on the master device detection signal. The slave device operates in slave mode. The Bluetooth connection request carries a master device identifier of the master device. The master device identifier can be an identifier for establishing a Bluetooth connection, such as a device number or device name of the master device.

[0079] It can be understood that the master device sends a Bluetooth connection request to the slave device only if the slave device is in slave mode and receives a master device detection signal.

[0080] S206, receiving the Bluetooth connection request, and establishing a Bluetooth connection with the current master device based on the Bluetooth connection request;

[0081] Specifically, if the master device includes one, the slave device receives the Bluetooth connection request sent by the master device based on the slave mode. When the slave device receives the Bluetooth connection request, the slave device establishes a Bluetooth connection with the master device based on the Bluetooth connection request. The Bluetooth connection is completed and there is no need to continue to execute steps S207-S214.

[0082] If there are multiple master devices, after establishing a Bluetooth connection with the current master device based on the Bluetooth connection request, the following steps S207 to S214 need to be performed. The current master device can be selected in descending order based on the master device signal strength or randomly selected. The signal strength can be obtained from the connectable signal.

[0083] S207, sending a connection confirmation pop-up window to the current master device based on the Bluetooth connection;

[0084] Specifically, the slave device sends a connection confirmation pop-up window to the current master device based on the Bluetooth connection, so that the current master device disconnects the Bluetooth connection after receiving the connection confirmation pop-up window.

[0085] S208, receiving a connection confirmation pop-up window sent by the slave device, and disconnecting the Bluetooth connection;

[0086] Specifically, the current master device receives the connection confirmation pop-up window sent by the slave device, displays it on the display interface, and then disconnects the Bluetooth connection.

[0087] S209, receiving the Bluetooth connection request, and establishing a Bluetooth connection with the current master device based on the Bluetooth connection request;

[0088] S210, sending a connection confirmation pop-up window to the current master device based on the Bluetooth connection;

[0089] S211, receiving a connection confirmation pop-up window sent by the slave device, and disconnecting the Bluetooth connection;

[0090] Steps S209 to S211 are to disconnect the Bluetooth connection with the current master device. After determining that the next master device is the current master device, the slave device repeats the steps performed with the current master device. When there is no next master device, it indicates that all detected master devices have completed the above process, and the following steps can be executed.

[0091] S212, receiving a selection instruction for the connection confirmation pop-up window, and sending a Bluetooth connection request to the slave device;

[0092] Specifically, the master device includes multiple devices, and the user selects a target master device from each of the master devices. When the master device receives the selection instruction in the connection confirmation pop-up window, the target master device sends a Bluetooth connection request to the slave device. The user can select the target master device by voice command, fingerprint authentication, touch command, etc.

[0093] S213, if no selection instruction for the connection confirmation pop-up window is received within the preset time, entering a standby state;

[0094] Specifically, a preset time period is set. After the master device disconnects the Bluetooth connection with the slave device, if the master device does not receive a selection instruction in the connection confirmation pop-up window within the preset time period, the master device enters a standby state. This prevents the master device from remaining in a waiting state without receiving a selection instruction in the connection confirmation pop-up window, thereby reducing the power consumption of the master device.

[0095] S214, receiving the Bluetooth connection request, and re-establishing a Bluetooth connection with the target master device based on the Bluetooth connection request;

[0096] Specifically, a Bluetooth connection request sent by the target host device is received, and a Bluetooth connection is re-established with the target host device based on the Bluetooth connection request. The target host device is the host device that receives the user's selection instruction in the connection confirmation pop-up window.

[0097] Please refer to Steps S206-S214 for details. Figure 5 , is a schematic diagram of an example of Bluetooth connection between a slave device and multiple master devices provided in an embodiment of the present application. Figure 5 As shown, the slave device is in slave mode, and the slave mode establishes a Bluetooth connection with the master device 1, sends a connection confirmation pop-up window to the master device 1 based on the Bluetooth connection, and then disconnects the Bluetooth connection. The connection and disconnection operations are completed for the master devices 2 and 3 in the same manner. The master devices 2 and 3 receive the connection confirmation pop-up windows in turn, and the user selects the target master device. As shown in the figure, the user selects the master device 2 as the target master device. The master device 2 receives the user's selection instruction on the connection confirmation pop-up window, and then re-establishes the Bluetooth connection with the slave device.

[0098] S215, if the Bluetooth connection exceeds the first duration, executing the step of determining that the slave device is in a pairing state and the reconnection fails;

[0099] Specifically, a first duration is pre-set, where the first duration refers to the maximum duration that the slave device cannot exceed when executing step S206. If the duration used by the slave device in executing step S206 exceeds the first duration, the step of determining that the slave device is in a pairing state and that the reconnection has failed is executed. This allows the slave device to re-execute the connection operation when it is unable to establish a Bluetooth connection with the master device for a long period of time, thereby improving connection efficiency and fault tolerance.

[0100] S216, if the Bluetooth connection exceeds the second duration, switching to a standby state;

[0101] Specifically, a second duration is pre-set, which refers to the maximum duration that the slave device can take from being turned on to establishing a Bluetooth connection. If the duration of time it takes for the slave device to establish a Bluetooth connection exceeds the second duration, the slave device switches to a standby state, which is a state where the slave device is powered on but not performing any substantive work. This can avoid repeated connection operations when the slave device has not established a Bluetooth connection with the master device for a long time, effectively reducing the power consumption of the slave device.

[0102] In an embodiment of the present application, when the slave device is in a pairing state and the backconnection fails, the working mode of the slave device is switched to the master mode. At this time, the slave device sends a master device detection signal based on the master mode to detect a connectable master device, the master device receives the master device detection signal, and then switches the working mode of the slave device back to the slave mode, and then the master device receives the master device detection signal and establishes a Bluetooth connection with the slave device based on the master device detection signal. The slave device automatically completes the search for the master device and the pairing process with the master device through the master-slave mode switching. The above method can be used for the connection and pairing methods of all master-slave devices. It is simple and universal, reduces the user's learning cost, and improves the user experience; the master device sends a master device detection signal to the slave device based on the master device detection signal carrying the slave device identifier. The present invention relates to a method for transmitting the Bluetooth connection of a slave device to a master device through a Bluetooth communication channel, wherein the slave device sends a Bluetooth connection request carrying the master device identifier, and then the slave device establishes a Bluetooth connection with the master device based on the Bluetooth connection request carrying the master device identifier, thereby ensuring the accuracy of the Bluetooth connection; the target master device is selected by the user through the selection instruction of the connection confirmation pop-up window, thereby further improving the reliability of the Bluetooth connection; by setting the first time length, the connection operation can be re-executed when the slave device cannot establish a Bluetooth connection with the master device for a long time, thereby improving the connection efficiency and fault tolerance; by setting the second time length, the connection operation can be avoided from being repeated when the slave device has not established a Bluetooth connection with the master device for a long time, thereby effectively reducing the power consumption of the slave device; by setting the preset time length, the master device is avoided from not receiving the selection instruction of the connection confirmation pop-up window and being in a waiting state for reception, thereby reducing the power consumption of the master device.

[0103] See Figure 6 , provides a flow chart of a Bluetooth connection method according to an embodiment of the present application. Figure 6 As shown, the embodiment of the present application describes the specific process of the Bluetooth connection method from the device side, and the method may include the following steps S301-S303.

[0104] S301, when it is determined that the slave device is in a pairing state and the backconnection fails, switching the working mode of the slave device to a master mode;

[0105] Specifically, the slave device works in slave mode by default, that is, before switching to master mode, the working mode of the slave device is slave mode. The Bluetooth system working mode of the slave device defaults to slave mode. When the slave device enters the pairing state and fails to reconnect, the Bluetooth system working mode of the slave device is switched to master mode.

[0106] The pairable state refers to the state in which the Bluetooth of the slave device is turned on and is not currently connected to any device, and can be paired with other master devices. The master mode refers to the working mode in which the slave device can detect and search for surrounding devices.

[0107] The reconnection failure may mean that there is no reconnectable device within the connectable range of the slave device, or that there is a reconnectable device within the connectable range but the reconnection fails. The reconnectable device refers to a device that has previously established a Bluetooth connection with the slave device and can be directly connected without re-pairing.

[0108] S302, detecting a connectable master device based on the master mode;

[0109] Specifically, a master device detection signal is sent based on the master mode, and the master device detection signal is used to detect a connectable master device. When the slave device detects a connectable master device based on the master device detection signal, it obtains a connectable signal fed back by the master device. Based on the connectable signal, the slave device can determine the number of connectable master devices. The number may include one or more.

[0110] The master device detection signal carries the slave device identification information of the slave device, and the slave device identification can be the device number, device name, etc. of the slave device used for Bluetooth connection. The connectable signal carries information such as signal strength and master device identification, and the master device identification can be the device number, device name, etc. of the master device used for Bluetooth connection.

[0111] S303: Switch the working mode of the slave device to a slave mode, and establish a Bluetooth connection with the master device based on the slave mode.

[0112] Specifically, the slave mode refers to an operating mode in which the slave device can establish a Bluetooth connection with the master device. If there is one master device, the slave device receives a Bluetooth connection request sent by the master device based on the slave mode. When the slave device receives the Bluetooth connection request, the slave device establishes a Bluetooth connection with the master device based on the Bluetooth connection request. If the master device includes multiple devices, a Bluetooth connection is established with the current master device among the master devices based on the slave mode. The current master device can be selected in order from strong to weak based on the master device signal strength or can be selected in random order. Then, a connection confirmation pop-up window is sent to the current master device based on the Bluetooth connection, so that the current master device disconnects the Bluetooth connection when receiving the connection confirmation pop-up window. Then, the next master device among the master devices is determined, and the next master device is used as the current master device. The steps of establishing a Bluetooth connection with the current master device among the master devices based on the slave mode are performed, and the connection and disconnection operations are completed in the same manner. When there is no next master device, it indicates that all detected master devices have completed the above process. Then, a target master device is selected from the multiple master devices according to the user's selection instruction on the connection confirmation pop-up window, and a Bluetooth connection with the target master device is established. The user can select the target master device in a manner that can be voice command, fingerprint authentication, touch command, etc.

[0113] In an embodiment of the present application, when a slave device is in a pairing state and fails to reconnect, the operating mode of the slave device is switched to master mode. At this time, the slave device sends a master device detection signal based on the master mode to detect a connectable master device, and then switches the operating mode to slave mode, thereby establishing a Bluetooth connection with the master device based on the slave mode. The slave device automatically completes the search for the master device and the pairing process with the master device through the master-slave mode switching. The above method can be used for the connection and pairing of all master and slave devices. It is simple and universal, reduces the user's learning cost, and improves the user experience.

[0114] See Figure 7 , provides a flow chart of a Bluetooth connection method according to an embodiment of the present application. Figure 7 As shown, the embodiment of the present application describes the specific process of the Bluetooth connection method from the device side, and the method may include the following steps S401-S409.

[0115] S401, when it is determined that the slave device is in a pairing state and there is currently no device to which it can reconnect, switching the working mode of the slave device to a master mode;

[0116] Specifically, the slave device works in slave mode by default, that is, before switching to master mode, the working mode of the slave device is slave mode. The Bluetooth system working mode of the slave device defaults to slave mode. When the slave device is in a pairing state and there is currently no device that can be connected back, the Bluetooth system working mode of the slave device is switched to master mode.

[0117] The pairable state refers to the state in which the Bluetooth of the slave device is turned on, is not currently connected to any device, and can be paired with other master devices. The reconnectable device refers to a device that has previously established a Bluetooth connection with the slave device and does not need to be re-paired and can be directly connected. The master mode refers to the working mode in which the slave device can detect and search for surrounding devices.

[0118] S402, when it is determined that the slave device is in a pairing state and there is a device to which it can reconnect, if the reconnection fails, switching the working mode of the slave device to a master mode;

[0119] Specifically, the slave device works in slave mode by default, that is, before switching to master mode, the working mode of the slave device is slave mode. The Bluetooth system working mode of the slave device defaults to slave mode. When the slave device is in a pairing state and there is a device that can be reconnected, if the reconnection fails, the Bluetooth system working mode of the slave device is switched to master mode.

[0120] S403, detecting a connectable master device based on the master mode;

[0121] Specifically, a master device detection signal is sent based on the master mode, and the master device detection signal is used to detect a connectable master device. When the slave device detects a connectable master device based on the master device detection signal, it obtains a connectable signal fed back by the master device. Based on the connectable signal, the slave device can determine the number of connectable master devices. The number may include one or more.

[0122] The master device detection signal carries the slave device identification information of the slave device, and the slave device identification can be the device number, device name, etc. of the slave device used for Bluetooth connection. The connectable signal carries information such as signal strength and master device identification, and the master device identification can be the device number, device name, etc. of the master device used for Bluetooth connection.

[0123] S404, switching the working mode of the slave device to slave mode;

[0124] Specifically, the slave mode refers to an operating mode in which the slave device can establish a Bluetooth connection with the master device.

[0125] S405, if there is one master device, waiting for a Bluetooth connection request sent by the master device, and establishing a Bluetooth connection with the master device based on the Bluetooth connection request;

[0126] S406, if there are multiple master devices, establishing a Bluetooth connection with each master device in sequence based on the slave mode and then disconnecting the Bluetooth connection;

[0127] Specifically, if the master device includes multiple devices, a Bluetooth connection is established with the current master device among the master devices based on the slave mode, and a connection confirmation pop-up window is sent to each of the current master devices based on the Bluetooth connection, so that the current master device disconnects the Bluetooth connection when receiving the connection confirmation pop-up window, determines the next master device among the master devices, uses the next master device as the current master device, and executes the step of establishing a Bluetooth connection with the current master device among the master devices based on the slave mode, and completes the connection and disconnection operations in the same manner.

[0128] The current master device may be selected based on the master device signal strength from strong to weak or may be selected in a random order.

[0129] S407, establishing a Bluetooth connection with the target master device based on the selection instruction for the target master device among the master devices;

[0130] Specifically, referring to step S406, when there is no next master device, indicating that all detected master devices have completed the above process, a Bluetooth connection is established with the target master device based on a selection instruction for the target master device among the master devices. The selection instruction may be a voice instruction.

[0131] S408, if the Bluetooth connection exceeds the first duration, executing the step of determining that the slave device is in a pairing state and the reconnection fails;

[0132] Specifically, a first duration is pre-set, where the first duration refers to the maximum duration that the slave device cannot exceed when executing step S206. If the duration used by the slave device in executing step S206 exceeds the first duration, the step of determining that the slave device is in a pairing state and that the reconnection has failed is executed. This allows the slave device to re-execute the connection operation when it is unable to establish a Bluetooth connection with the master device for a long period of time, thereby improving connection efficiency and fault tolerance.

[0133] S409: If the Bluetooth connection exceeds the second duration, switch to a standby state.

[0134] Specifically, a second duration is pre-set, which refers to the maximum duration that the slave device can take from being turned on to establishing a Bluetooth connection. If the duration of time it takes for the slave device to establish a Bluetooth connection exceeds the second duration, the slave device switches to a standby state, which is a state where the slave device is powered on but not performing any substantive work. This can avoid repeated connection operations when the slave device has not established a Bluetooth connection with the master device for a long time, effectively reducing the power consumption of the slave device.

[0135] In an embodiment of the present application, when the slave device is in a pairing state and the reconnection fails, the working mode of the slave device is switched to the master mode. At this time, the slave device sends a master device detection signal based on the master mode to detect a connectable master device. The master device receives the master device detection signal, and then switches the working mode of the slave device back to the slave mode. If the master device includes one, a Bluetooth connection is established with the master device based on the slave mode. If the master device includes multiple, a Bluetooth connection is established with each of the master devices in turn based on the slave mode and then the Bluetooth connection is disconnected. A connection confirmation pop-up window is sent and a connection confirmation is made based on the user's connection. , the slave device automatically completes the search for the master device and the pairing process with the master device through the master-slave mode switching. The above method can be used for all master-slave device connection and pairing methods. It is simple and universal, reduces the user's learning cost, and improves the user experience. By setting the first duration, when the slave device cannot establish a Bluetooth connection with the master device for a long time, the connection operation can be re-executed, thereby improving the connection efficiency and fault tolerance rate. By setting the second duration, when the slave device has not established a Bluetooth connection with the master device for a long time, the connection operation can be avoided repeatedly, thereby effectively reducing the power consumption of the slave device.

[0136] See Figure 8 , provides a flow chart of a Bluetooth connection method according to an embodiment of the present application. Figure 8 As shown, the embodiment of the present application describes the specific process of the Bluetooth connection method from the main device side, and the method may include the following steps S501-S502.

[0137] S501, receiving a master device detection signal sent by a slave device, wherein the master device detection signal is a signal sent to detect a connectable master device when the slave device is in a pairing state and fails to reconnect, switching the working mode to the master mode;

[0138] Specifically, the master device receives a master device detection signal and feeds back a connectable signal. The master device detection signal carries the slave device identifier of the slave device, which can be an identifier for Bluetooth connection, such as the device number or device name of the slave device. The connectable signal carries information such as signal strength and the master device identifier, which can be an identifier for Bluetooth connection, such as the device number or device name of the master device.

[0139] S502, establishing a Bluetooth connection with the slave device based on the master device detection signal, and switching the working mode of the slave device to a slave mode;

[0140] Specifically, the master device detection signal carries the slave device identification information of the slave device, and the master device establishes a Bluetooth connection with the slave device based on the slave device identification. At this time, the slave device is in a slave mode.

[0141] In an embodiment of the present application, by receiving a master device detection signal sent by a slave device and establishing a Bluetooth connection with the slave device based on the master device detection signal, the above method can be used for connection pairing of all master and slave devices. It is simple and universal, reduces the user's learning cost, and improves the user experience.

[0142] See Figure 9 , provides a flow chart of a Bluetooth connection method according to an embodiment of the present application. Figure 9 As shown, the embodiment of the present application describes the specific process of the Bluetooth connection method from the main device side, and the method may include the following steps S601-S607.

[0143] S601, receiving a master device detection signal sent by a slave device, wherein the master device detection signal is a signal sent to detect a connectable master device when the slave device is in a pairing state and fails to reconnect, switching the working mode to a master mode;

[0144] Specifically, the master device receives a master device detection signal and feeds back a connectable signal. The master device detection signal carries the slave device identifier of the slave device, which can be an identifier for Bluetooth connection, such as the device number or device name of the slave device. The connectable signal carries information such as signal strength and the master device identifier, which can be an identifier for Bluetooth connection, such as the device number or device name of the master device.

[0145] S602, sending a Bluetooth connection request to the slave device based on the master device detection signal;

[0146] Specifically, when the slave device receives a master device detection signal, the master device sends a Bluetooth connection request to the slave device based on the master device detection signal. The slave device operates in slave mode. The Bluetooth connection request carries the master device identifier of the master device. The master device identifier can be an identifier for the master device, such as a device number or device name, used for Bluetooth connection.

[0147] It can be understood that the master device sends a Bluetooth connection request to the slave device only if the slave device is in slave mode and receives a master device detection signal.

[0148] S603, receiving connection confirmation information sent by the slave device based on the Bluetooth connection request, and establishing a Bluetooth connection with the slave device;

[0149] Specifically, the master device receives the connection confirmation information and then establishes a Bluetooth connection with the slave device. The connection confirmation information is sent to the master device after the slave device receives the Bluetooth connection request, confirms the master device identifier based on the Bluetooth connection request and the connectable signal, and then sends it to the master device.

[0150] S604, receiving a connection confirmation pop-up window sent by the slave device, and disconnecting the Bluetooth connection;

[0151] Specifically, if the connection confirmation pop-up window sent by the slave device is not received, the Bluetooth connection is completed; if the connection confirmation pop-up window sent by the slave device is received, the interface displays the connection confirmation pop-up window and disconnects the Bluetooth connection.

[0152] S605, receiving a selection instruction for the connection confirmation pop-up window, and sending a Bluetooth connection request to the slave device;

[0153] Specifically, the master device includes multiple devices, and the user selects a target master device from each of the master devices. When the master device receives the selection instruction in the connection confirmation pop-up window, the target master device sends a Bluetooth connection request to the slave device. The user can select the target master device by voice command, fingerprint authentication, touch command, etc.

[0154] S606, if no selection instruction for the connection confirmation pop-up window is received within the preset time, entering a standby state;

[0155] Specifically, a preset time period is set. After the master device disconnects the Bluetooth connection with the slave device, if the master device does not receive a selection instruction in the connection confirmation pop-up window within the preset time period, the master device enters a standby state. This prevents the master device from being in a state of waiting for a selection instruction in the connection confirmation pop-up window without receiving the selection instruction, thereby reducing the power consumption of the master device.

[0156] S607: Receive connection confirmation information sent by the slave device based on the Bluetooth connection request, and re-establish a Bluetooth connection with the slave device.

[0157] In an embodiment of the present application, a master device detection signal is received from a slave device, and then a Bluetooth connection is established with the slave device based on the master device detection signal. If a connection confirmation pop-up window is received from the slave device, the Bluetooth connection is disconnected, and then a Bluetooth connection is re-established with the slave device based on the user's selection instruction for the connection confirmation pop-up window. The above method can be used for the connection pairing method of all master-slave devices. It is simple and universal, reduces the user's learning cost, and improves the user experience. The target master device is selected by the user's selection instruction for the connection confirmation pop-up window, which further improves the reliability of the Bluetooth connection. By setting a preset time length, the master device is prevented from not receiving the selection instruction for the connection confirmation pop-up window and being in a state of waiting for reception, which can reduce the power consumption of the master device.
