detailed description

In order to make the objectives, technical solutions and advantages of the present application clearer, some embodiments of the present application will be described in detail below by way of examples in conjunction with the accompanying drawings. However, one of ordinary skill in the art will appreciate that in each instance, numerous technical details are set forth in order to provide the reader with a better understanding of the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can be realized.

The embodiment of the present application provides an address transmission method for a first Bluetooth terminal, and the specific first Bluetooth terminal may be a Bluetooth chip or an electronic device, such as a TWS (True Wireless Stereo, true wireless stereo) Bluetooth headset, a speaker Wait. In some scenarios, the first Bluetooth end can be understood as the master device end, and the second Bluetooth end can be understood as the slave device end; in other scenarios, the first Bluetooth end can also be understood as the slave device end, and the second Bluetooth end can be understood as the slave device end. Understand the main device side. For example, in the forwarding mode, the master device is used to forward voice data to the slave device, and in the monitoring mode, the master device is used to send synchronous data. Please refer to FIG. 1, the address transmission method includes the following steps:

S101: Establish a first Bluetooth connection with the second Bluetooth terminal through the default address of the first Bluetooth terminal; the first Bluetooth connection is a classic Bluetooth connection or a low-power Bluetooth connection;

S102: Send the device address of the first Bluetooth end to the second Bluetooth end through the first Bluetooth connection, and receive the device address of the second Bluetooth end sent by the second Bluetooth end through the first Bluetooth connection.

In this embodiment, for convenience of description, the Bluetooth connection established through the default address may be referred to as the first Bluetooth connection, and the Bluetooth connection established through the device address may be referred to as the second Bluetooth connection, that is, between the first Bluetooth terminal and the second Bluetooth connection The Bluetooth connection established under the condition that the Bluetooth terminals do not know the device address of each other is called the first Bluetooth connection, and the Bluetooth connection established after the device addresses are known to each other is called the second Bluetooth connection. The address transmission method is applied to the first bluetooth end, and the first bluetooth end and the second bluetooth end are TWS bluetooth earphones as an example for illustration, and the left earphone and the right earphone of the TWS earphone record at least three addresses respectively. The addresses recorded by the left earphone include the default address, the left earphone device address, and the left earphone pairing address. Among them, the default address can be understood as a unified fixed address for all Bluetooth devices. The default address cannot be changed. The default addresses of the left earphone, the right earphone and other earphones are configured the same. Specifically, the format of the default address and the device address of the left earphone , the right earphone device address has the same format, for example, it can be data represented by 48-bit (6-byte) binary. The device address of the left earphone is the unique device address of the left earphone and cannot be changed. The pairing address of the left earphone is the unique device address of any right earphone paired with the left earphone. The pairing address of the left earphone can be modified by the address transmission method. Similarly, the address recorded by the right earphone also includes the default address, the device address of the right earphone and the pairing address of the right earphone. The pairing address of the right earphone is the unique device address of the right earphone and cannot be changed. The pairing address of the right earphone is any device that is paired with the right earphone. The unique device address of the left earphone and the pairing address of the right earphone can be modified by the address transmission method. It is understandable that the device address of any Bluetooth device is different. In addition, a Bluetooth device can only use one address at the same time. It is understandable that different addresses correspond to different frequency hopping sequences. For example, when a classic Bluetooth connection is established In the process, the master device (Master) calculates the frequency hopping sequence of the ID packet sent according to the device address of the slave device (Slave), and the slave device calculates the frequency hopping sequence of the received ID packet according to its own device address. The sequence is the same. When the left and right earphones use the same frequency hopping sequence, the left and right earphones can communicate with each other. For example, if the left earphone sends a command to create a Bluetooth connection to the Bluetooth terminal using the default address stored in the left earphone, and the right earphone uses the default address of the right earphone to enter the message receiving mode, the left and right earphones can establish a Bluetooth connection through the default address to communicate messages; or , the right earphone sends a command to create a Bluetooth connection to the Bluetooth terminal using the default address, and the left earphone uses the default address of the left earphone to enter the message receiving mode, then the left and right earphones can establish a Bluetooth connection through the default address to communicate messages. In addition, if two Bluetooth devices have been paired and know each other's device address, they can also establish a connection for communication. For example, the left earphone can send the Bluetooth end of the device address of the right earphone stored by itself to create a Bluetooth connection. Command, the right earphone can use the right earphone device address to enter the message receiving mode to receive the create Bluetooth connection command sent by the left earphone, and the left and right earphones can establish a low energy bluetooth connection or low energy bluetooth connection through the left earphone device address and the right earphone device address . In this embodiment, a classic Bluetooth connection is also called a BR (basic rate, basic rate) connection or an EDR (enhanced datarate, enhanced rate) connection, or can also be called an ACL (ASYNCHRONOUS LOGICAL LINKS, asynchronous logical link) connection; Low-power Bluetooth connection can also be called LE (Low Energy, low power) connection, or can also be called LEACL (Low Energy ASYNCHRONOUS LOGICAL LINKS, low-power asynchronous logic link) connection, the Bluetooth headset is set in the factory When the device address of the left earphone is used for the left earphone, the device address of the right earphone is used for the right earphone, and the respective default addresses have also been configured, that is, the default address of the first Bluetooth terminal and the second Bluetooth terminal can be configured according to the requirements. address and device address. The configured default address and device address can be stored in the first Bluetooth terminal and the second Bluetooth terminal. Generally, for any Bluetooth terminal, the default address is different from the device address.

In step S101, a first Bluetooth connection is established with the second Bluetooth terminal through the default address of the first Bluetooth terminal. Specifically, the first Bluetooth terminal sends a Bluetooth connection creation command to the second Bluetooth terminal according to the default address of the first Bluetooth terminal to create a Bluetooth connection. The connection command includes the default address of the first Bluetooth terminal. In addition, the Bluetooth connection creation command may also include information such as the ID of the Bluetooth device and the characteristic parameters of the controller. The create bluetooth connection command is used to establish a classic bluetooth connection or a low energy bluetooth connection between the first bluetooth end and the second bluetooth end. The default address of the first bluetooth terminal is the same as the default address of the second bluetooth terminal, and it can also be understood that the bluetooth connection between the first bluetooth terminal and the second bluetooth terminal is established through the default address of the first bluetooth terminal and the default address of the second bluetooth terminal. For two earphones that do not know the address of each other's device, if they need to become a pair of earphones, they can first establish a classic Bluetooth connection or an LE connection through the same default address. It can be understood that, in this case, the first Bluetooth connection and the second Bluetooth connection do not know each other's device address, so the first Bluetooth terminal and the second Bluetooth terminal cannot establish a connection through the device address. If there are multiple bluetooth terminals using the default address at this time, the first bluetooth terminal may be connected with multiple second bluetooth terminals. In this case, the first bluetooth terminal can select a second bluetooth terminal, for example, select one The second bluetooth terminal with the largest RSSI, that is, choose a second bluetooth terminal that is closest to it, or choose the bluetooth terminal that responds first to establish a bluetooth connection. The first bluetooth terminal can establish a classic bluetooth connection with the selected second bluetooth terminal or LE connection. The address transmission method can also be used for the second bluetooth terminal. In step S101, the first bluetooth connection can also be initiated and established by the second bluetooth terminal, that is, the second bluetooth terminal can also communicate with the first bluetooth terminal through the default address of the second bluetooth terminal. The Bluetooth terminal establishes the first Bluetooth connection. Specifically, the second Bluetooth terminal sends the Bluetooth terminal that uses the default address of the second Bluetooth terminal to create a Bluetooth connection. If the first Bluetooth terminal is using the default address and is in the message receiving mode, the first Bluetooth terminal The command to create a bluetooth connection will be received, and an ACK (Acknowledge character, confirmation character) will be returned to the second bluetooth terminal to establish a bluetooth connection, thereby realizing address transmission.

In step S102, after the first Bluetooth connection is established, it can send its own device address to each other through the first Bluetooth connection, that is, the first Bluetooth terminal sends the device address of the first Bluetooth terminal to the second Bluetooth terminal through the first Bluetooth connection. Bluetooth terminal, and the second bluetooth terminal sends the device address of the second bluetooth terminal to the first bluetooth terminal through the first bluetooth connection, the first bluetooth terminal can receive the device address of the second bluetooth terminal, and the second bluetooth terminal can also receive the first bluetooth terminal. A device address of the Bluetooth terminal, so as to realize the intercommunication of device addresses. In addition, the address transmission method can also be used for the second bluetooth terminal, that is, in step S102, through the first bluetooth connection, the second bluetooth terminal sends the device address of the second bluetooth terminal to the first bluetooth terminal, and the second bluetooth terminal is connected. The device address of the first Bluetooth terminal sent by the first Bluetooth terminal is received.

In the address transmission method provided by the embodiment of the present application, since the default addresses of the first Bluetooth end and the second Bluetooth end are the same, after the first Bluetooth end sends the Bluetooth connection creation command to the Bluetooth end using the default address of the first Bluetooth end, because the second Bluetooth end The Bluetooth terminal uses the default address of the second Bluetooth terminal to receive messages, so the second Bluetooth terminal can receive the command to create a Bluetooth connection, so that the Bluetooth connection can be successfully established. First establish a Bluetooth connection through the default address, and then transmit the device address through the Bluetooth connection, so that both the first Bluetooth end and the second Bluetooth end can know the device address of the other party, avoiding the need for the first Bluetooth end, the second Bluetooth end and the The charging box is additionally provided with pins for transmitting data, so the structure is simple and the cost is low.

Based on the contents disclosed in the foregoing embodiments, in this embodiment, referring to FIG. 2 , an address transmission method may include the following steps:

S201: judge whether the preset condition is met; if so, execute step S202, if not, execute step S201A: continue to judge whether the preset condition is met with the preset time sequence;

S202: Establish a first Bluetooth connection with the second Bluetooth terminal through the default address of the first Bluetooth terminal; the first Bluetooth connection is a classic Bluetooth connection or a low-power Bluetooth connection;

S203: Send the device address of the first Bluetooth end to the second Bluetooth end through the first Bluetooth connection, and the first Bluetooth end receives the device address of the second Bluetooth end sent by the second Bluetooth end through the first Bluetooth connection.

In this embodiment, steps S202-S203 are the same as or similar to steps S101 and S102 in the foregoing embodiment, and are not repeated here. In step S201, it is necessary to judge whether the preset conditions are met, and only when the preset conditions are met, the address transmission in the foregoing embodiment is performed, that is, only when the preset conditions are met, the first Bluetooth terminal performs the first Bluetooth terminal according to the default conditions of the first Bluetooth terminal. The address sending the Bluetooth connection creation command to the second Bluetooth terminal can also be understood as the first Bluetooth terminal sending the Bluetooth connection creation command to the Bluetooth terminal using the default address of the first Bluetooth terminal. It can be understood that, if the first Bluetooth end and the second Bluetooth end do not know each other's device addresses, the first Bluetooth connection can be established through the same default address to realize address transmission. In this embodiment, the preset condition may be that the first bluetooth terminal and the second bluetooth terminal do not save each other's device address, for example, the bluetooth terminal that established a bluetooth connection with the first bluetooth terminal last time is lost, so the first bluetooth terminal needs to obtain The address of the new second bluetooth terminal to be paired with. In addition, if the first bluetooth terminal does not store the device addresses of other bluetooth terminals, the address transmission method of the foregoing embodiment can also be executed, so that the first bluetooth terminal can obtain the second bluetooth terminal. device address of the terminal. The preset sequence in step S201A may be to determine whether the preset condition is satisfied once per second, or to determine whether the preset condition is satisfied once per minute.

Based on the contents disclosed in the above embodiments, in this embodiment, the first Bluetooth terminal is the left earphone and the second Bluetooth terminal is the right earphone as an example for description. If the user loses one of a pair of earphones, or one of the pair of earphones is damaged, in the face of such a situation that only one earphone can be used, the user can buy a new earphone and one that can be used normally. The earphones are paired for use, but the newly bought earphones and the original earphones do not know each other's device address. Based on this, the address transmission operation needs to be performed, so that the left and right earphones can obtain each other's device address, so that the left and right earphones can further Establish an LE connection or a classic Bluetooth connection via the device address. Referring to Figure 3, the process of address transmission may include the following steps:

S301: judge whether the preset condition is met; if so, execute step S302, if not, execute step S301A: continue to judge whether the preset condition is met with the preset time sequence;

S302: establish a classic bluetooth connection or low-power bluetooth connection between the main earphone and the auxiliary earphone through the default address saved by the main earphone;

S303: the main earphone sends the main earphone address to the secondary earphone through the established Bluetooth connection, and the secondary earphone sends the secondary earphone address to the main earphone through the established Bluetooth connection;

S304: Disconnect the established Bluetooth connection;

In step S301, satisfying the preset condition is the premise of executing S302, that is, if the preset condition is met, the first Bluetooth connection is established, which can avoid the waste of power consumption due to frequent activation of the address transmission process in the foregoing embodiment. Specifically, the preset conditions may include the following methods. For example, it can be determined whether the buttons on the two earphones are pressed and held at the same time. If they are pressed for a long time at the same time, the preset conditions are satisfied. As a result, S302 is triggered by mistake; in addition, it can also be realized through the mobile phone APP. Specifically, it can be determined whether there are two earphones in the Bluetooth list of the mobile phone that are selected and selected to perform reset at the same time. If so, the preset is satisfied. condition, but this trigger condition is more complicated, which brings tedious operation to the user. Step S301A is the same as or similar to step S201A in the foregoing embodiment, and is not repeated here.

Based on the contents disclosed in the foregoing embodiments, in this embodiment, the preset condition may include one or both of the first preset condition and the third preset condition.

The first preset condition is that the preset reset button on the charging box is activated. Specifically, if the user wants to make two headphones that are not originally a pair can establish a Bluetooth connection to become a pair, that is, they want to make the two headphones have no communication before. If you want to communicate with the past headset, you can touch the preset reset button on the charging box to enable the address transmission process in the foregoing embodiment, so that the first Bluetooth terminal and the second Bluetooth terminal can obtain each other's device address, thereby This enables the first Bluetooth terminal and the second Bluetooth terminal to establish an LE connection or a classic Bluetooth connection according to the device address. In this embodiment, the preset reset button may also be a physical button or a virtual button, and the touch duration of the preset reset button is not limited. If the preset condition is set to long-press the reset button, other function buttons can be reused. For example, the first preset condition can be set as the preset reset button on the charging box is long-pressed for more than 5s.

The third preset condition is that the establishment of the Bluetooth connection between the first Bluetooth terminal and the second Bluetooth terminal through the device address fails. Specifically, the establishment of the Bluetooth connection between the first Bluetooth terminal and the second Bluetooth terminal through the device address fails, which may be Since the first bluetooth terminal and the second bluetooth terminal do not know each other's device address, the bluetooth connection cannot be successfully established through the device address. In this case, the first bluetooth terminal and the second bluetooth terminal cannot be identified as one For earphones, it can be understood that if two earphones have been paired as a pair of earphones, the two earphones should know each other's device address. Specifically, the left earphone needs to know the right earphone address, or the right earphone needs to know the address of the right earphone. Know the address of the left earphone, so that a Bluetooth connection can be established between the two to exchange information, for example, to implement forwarding mode. Therefore, when the first bluetooth terminal and the second bluetooth terminal fail to establish a bluetooth connection through the device address, the address transmission process can be started, that is, the first bluetooth terminal sends a bluetooth connection creation command to the second bluetooth terminal according to the default address of the first bluetooth terminal , so that the first bluetooth terminal and the second bluetooth terminal can establish a bluetooth connection through the default address to obtain each other's device address, so that the first bluetooth terminal and the second bluetooth terminal can communicate through the device address without using default address. In this embodiment, the third preset condition is that the establishment of the Bluetooth connection between the first Bluetooth terminal and the second Bluetooth terminal through the device address fails, and the number of times that the Bluetooth connection fails to be established through the device address is not limited. For example, the first preset The set condition may be that the number of failures to establish a Bluetooth connection between the first Bluetooth terminal and the second Bluetooth terminal exceeds a preset number of times, and the preset number of times may be 1 time, 2 times, 3 times, etc., when the preset number of times is 2 times or 3 times, it can be understood that the first bluetooth terminal has tried to establish a bluetooth connection with the second bluetooth terminal through the device address many times, but all failed. address, at this time, a Bluetooth connection needs to be established through the default address, and through the Bluetooth connection, the first Bluetooth terminal and the second Bluetooth terminal can obtain the device address of each other. In addition, the behavior of establishing a Bluetooth connection between the first Bluetooth terminal and the second Bluetooth terminal through the default address may be established by the first Bluetooth terminal initiatively initiated or initiated by the second Bluetooth terminal. limited. In this embodiment, the failure to establish a Bluetooth connection between the first Bluetooth terminal and the second Bluetooth terminal by using the device address includes: the first Bluetooth terminal does not receive the second confirmation character from the second Bluetooth terminal within the preset time, and the second confirmation The character is the response of the second bluetooth terminal to the bluetooth connection creation command sent by the first bluetooth terminal to the bluetooth terminal using the pairing address of the first bluetooth terminal stored by the first bluetooth terminal. It can be understood that when the Bluetooth connection between the first Bluetooth terminal and the second Bluetooth terminal is established through the device address, the first Bluetooth terminal sends the Bluetooth terminal that uses the pairing address of the first Bluetooth terminal stored in the first Bluetooth terminal to create a Bluetooth connection. The connection command, the create bluetooth connection command is used to establish a classic bluetooth connection or a low-power bluetooth connection between the first bluetooth terminal and the second bluetooth terminal. In addition, if the reset button on the charging box is touched by mistake, even if the Bluetooth addresses are known to each other, if the two Bluetooth terminals are far away, the Bluetooth connection cannot be successfully established through the device address. far, establishing a bluetooth connection using the default address will also fail. After the two bluetooth terminals are closer, if the two bluetooth terminals do not know the device address of each other, they can still try to establish a bluetooth connection by relying on the default address.

Based on the content disclosed in the above embodiments, in this embodiment, the preset conditions may include a first preset condition and a third preset condition, that is, the preset reset button on the charging box is activated, and the first Bluetooth is established through the device address. If the low-power connection between the terminal and the second Bluetooth terminal fails, the first Bluetooth terminal establishes a first Bluetooth connection with the second Bluetooth terminal through the default address of the first Bluetooth terminal. It is understandable that, assuming that the reset button is preset on the charging box, the user may accidentally touch the reset button sometimes, but the left and right earphones actually know each other's device address, so there is no need for address transmission at this time. The condition is set to not only be activated by the reset button preset on the charging box, but also include the failure to establish a Bluetooth connection between the first Bluetooth terminal and the second Bluetooth terminal through the device address. If the preset reset button of the device is activated by mistake, if the Bluetooth connection is successfully established between the first Bluetooth terminal and the second Bluetooth terminal through the device address, the address transmission will not be performed to avoid unnecessary power consumption.

Based on the content disclosed in the above embodiments, in this embodiment, it is also possible to first determine whether the first preset condition is met. If the first preset condition is met, the first Bluetooth terminal sends the created Bluetooth terminal to the Bluetooth terminal using the pairing address of the first Bluetooth terminal. Bluetooth connection command, and then determine whether the third preset condition is satisfied, and if the third preset condition is also satisfied, the address transmission method in the foregoing embodiment can be executed. Referring to FIG. 4 , the address transmission method of this embodiment may include the following steps:

S401: Determine whether the first preset condition is met; if the first preset condition is met, perform step S402;

S402: The first bluetooth terminal sends a bluetooth connection creation command to the bluetooth terminal using the pairing address of the first bluetooth terminal;

S403: Determine whether the first bluetooth terminal has received a response to the command to create a bluetooth connection sent by the second bluetooth terminal; if the response is not received, perform step S404;

S404: The first bluetooth terminal sends a create bluetooth connection command to the bluetooth terminal using the default address of the first bluetooth terminal to establish a first bluetooth connection with the second bluetooth terminal;

S405: Send the device address of the first Bluetooth end to the second Bluetooth end through the first Bluetooth connection, and the first Bluetooth end receives the device address of the second Bluetooth end sent by the second Bluetooth end through the first Bluetooth connection.

In step S401, if the first preset condition is not met, it means that the preset reset button on the charging box has not been activated, that is, the user does not need to establish a connection between the two earphones at present, then step S401A can be executed: to preset Set the time sequence to continue to judge whether the preset condition is met; in step S403, if the third preset condition is not met, that is, although the reset button is activated, the Bluetooth connection between the first Bluetooth terminal and the second Bluetooth terminal is successfully established through the device address. , it means that the user may have touched the reset button on the charging box by mistake. In fact, the first Bluetooth terminal and the second Bluetooth terminal know each other's device address. Therefore, the two can successfully pass the two The device address of the user establishes a Bluetooth connection. At this time, it can be judged whether the preset conditions are met according to the preset time sequence, so as to confirm whether the transmission of the device address needs to be completed through the default address at the next moment. Steps S404 and S405 are the same as or similar to steps S102 and S103 in the foregoing embodiments, and will not be repeated here. In this embodiment, it is first determined whether the preset reset button on the charging box is activated. If activated, it is determined whether the establishment of the Bluetooth connection through the device address fails. If it fails, the Bluetooth connection is established through the default address. If the Bluetooth connection is established through the default address The connection is successful, so that the first Bluetooth terminal and the second Bluetooth terminal can send their respective device addresses to each other through the Bluetooth connection. In this embodiment, since the probability of the preset reset button on the charging box being pressed is low, compared with the preset condition of first judging whether the establishment of the Bluetooth connection through the device address fails, and then judging whether the reset button is pressed, In this embodiment, it is more effective to first determine whether the preset reset button on the charging box is pressed, and then determine whether the Bluetooth connection fails to be established through the device address. Specifically, this can prevent the headset from passing the device address. Constantly trying to connect with other headphones via bluetooth wastes power consumption. Step S401A is the same as or similar to step S201A in the foregoing embodiment, and details are not repeated here.

Based on the contents disclosed in the above embodiments, in this embodiment, the preset condition may further include a second preset condition, and the second preset condition is that both the first Bluetooth terminal and the second Bluetooth terminal are placed in the charging box. Specifically, for example, if it is detected that the first bluetooth terminal and the second bluetooth terminal are placed in the charging box, and the preset reset button on the charging box is activated, and the preset conditions are met, the Bluetooth connection can be established through the default address. And the first bluetooth terminal and the second bluetooth terminal can send their respective device addresses to each other through the bluetooth connection, so that the first bluetooth connection and the second bluetooth connection can receive the other party's device address. Specifically, for another example, if the first bluetooth terminal and the second bluetooth terminal are placed in the charging box, and the establishment of a bluetooth connection between the first bluetooth terminal and the second bluetooth terminal through the device address fails, the preset conditions are met, then A first bluetooth connection can be established and the first bluetooth end and the second bluetooth end can send their respective device addresses to each other through the first bluetooth connection, so that the first bluetooth end and the second bluetooth end can receive each other's device address . Put the two earphones into the charging box and touch or press the reset button on the charging box to establish the first Bluetooth connection. Compared with the solution of putting the two earphones into the charging box for address transmission, it avoids wasting energy. consumption, because not every time the headset is put into the charging box is for address transmission, more often it is just to charge the headset. In this embodiment, for the first Bluetooth terminal, please refer to FIG. 5 , the address transmission method in this embodiment includes the following steps:

S501: determine that the preset reset button on the charging box is activated; if the preset reset button on the charging box is activated, then execute step S502; if the preset reset button on the charging box is not activated, execute step S501A: with The preset timing continues to determine whether the preset conditions are met;

S502: Determine whether the first Bluetooth terminal is placed in the charging box; if the first Bluetooth terminal is placed in the charging box, go to step S503; if not, go to step S501A;

S503: The first Bluetooth terminal sends a Bluetooth connection creation command to the Bluetooth terminal using the pairing address of the first Bluetooth terminal;

S504: Determine whether the first bluetooth terminal receives a response to the command to create a bluetooth connection sent by the second bluetooth terminal; if the first bluetooth terminal receives a response to the command to create a bluetooth connection sent by the second bluetooth terminal, perform steps S505; if not satisfied, execute step S501A;

S505: Establish a first Bluetooth connection with the second Bluetooth terminal through the default address of the first Bluetooth terminal;

S506: Send the device address of the first Bluetooth end to the second Bluetooth end through the first Bluetooth connection, and the first Bluetooth end receives the device address of the second Bluetooth end sent by the second Bluetooth end through the first Bluetooth connection.

In this embodiment, steps S505 and S506 are the same as or similar to steps S202 and S203 in the foregoing embodiment, and are not repeated here. In this embodiment, it is first determined whether the preset reset button on the charging box is activated. If activated, it is then determined whether the first Bluetooth terminal and the second Bluetooth terminal are placed in the charging box. The bluetooth terminals are placed in the charging box, and then it is determined whether the establishment of the bluetooth connection between the first bluetooth terminal and the second bluetooth terminal through the device address fails. If it fails, the first bluetooth terminal and the second bluetooth terminal pass the default address. A first Bluetooth connection is established, and the first Bluetooth terminal and the second Bluetooth terminal send their respective device addresses to each other through the first Bluetooth connection, so as to realize address transmission and facilitate subsequent communication between the first Bluetooth terminal and the second Bluetooth terminal through the device address. . Step S501A is the same as or similar to step S201A in the foregoing embodiment, and is not repeated here.

Based on the content disclosed in the above embodiments, in this embodiment, if the first preset condition and the second preset condition are satisfied, the charging box sends the preset level sequence to the first Bluetooth terminal, for example, sending a certain sequence of high level and A sequence consisting of a low level is sent to the first Bluetooth terminal. After the first bluetooth terminal receives the preset level sequence, the first bluetooth terminal sends a command to create a bluetooth connection to the bluetooth terminal using the default address of the first bluetooth terminal; or after the first bluetooth terminal receives the preset level sequence, The first bluetooth terminal sends a command to create a bluetooth connection to the bluetooth terminal using the pairing address of the first bluetooth terminal and judges whether the third preset condition is satisfied. If the third predetermined condition is satisfied, the first bluetooth terminal sends the default address using the first bluetooth terminal to the The bluetooth side sends the create bluetooth connection command. For the second Bluetooth terminal, if the first or fifth preset conditions are met, the charging box sends the preset level sequence to the first Bluetooth terminal. After the second bluetooth terminal receives the preset level sequence, the second bluetooth terminal can use the default address of the second bluetooth terminal to configure the message receiving mode, so that the second bluetooth terminal can receive the message from the first bluetooth terminal to the first bluetooth terminal. A Bluetooth connection creation command sent by the Bluetooth end with the default address, so that the first Bluetooth end and the second Bluetooth end establish a first Bluetooth connection; or, after the second Bluetooth end receives the preset level sequence, the second Bluetooth end uses the first Bluetooth connection.
