Referring to FIG1 , there is shown an application scenario diagram of the Bluetooth connection establishment method provided in an embodiment of the present application. The Bluetooth connection establishment method is applied in an interactive system consisting of a Bluetooth device 10, an electronic device 20 and a server 30. The electronic device 20 receives the Bluetooth broadcast data sent by the Bluetooth device 10, generates a key according to the Bluetooth broadcast data or obtains the key from the server 30, and sends the key to the Bluetooth device 10 for authentication. After receiving the authentication success information returned by the Bluetooth device 10, the electronic device 20 communicates with the Bluetooth device 10, so that when the electronic device 20 communicates with the Bluetooth device 10, the user is unaware of the connection process and the process of the user performing the connection operation is simplified.

It should be noted that in FIG1 , the Bluetooth device 10 is an energy storage device, and the electronic device 20 is a mobile phone. The above examples are only for illustrative purposes and are not limited to this in actual applications. It can be understood that the Bluetooth device 10 can be an IoT device with Bluetooth function, including but not limited to, for example, mobile energy storage devices, household energy storage devices, mobile air conditioners, household air conditioners, lawn mowers, sweepers, smart power distribution panels, etc. The electronic device 20 can be a terminal device such as a tablet computer or a personal computer.

Referring to FIG. 2, a flow chart of a method for establishing a Bluetooth connection provided in an embodiment of the present application is shown. The above-mentioned method for establishing a Bluetooth connection can be applied to the electronic device 20 shown in FIG. 1. As shown in FIG. 2, the method for establishing a Bluetooth connection specifically includes the following steps. According to different requirements, the order of the steps in the flow chart can be changed, and some steps can be omitted. As shown in FIG. 2, the method for establishing a Bluetooth connection in an embodiment of the present application includes steps 201-206.

Step 201: receiving Bluetooth broadcast data sent by a Bluetooth device.

Step 202: Display the icon corresponding to the Bluetooth device.

Step 203: In response to the user's operation on the above icon, a connection is established with the Bluetooth device according to the device information.

Step 204: If the binding identifier is the first identifier, a key acquisition request is sent to the server according to the information of the target user currently logging into the electronic device and the device information.

Step 205: Receive the key returned by the server and send the key to the Bluetooth device for authentication.

Step 206: After receiving the authentication success information returned by the Bluetooth device, the electronic device communicates with the Bluetooth device through connection.

For the specific implementation contents of steps 201-206 of FIG. 2 in the embodiment of the present application, please refer to the implementation contents of steps 301-306 of the Bluetooth connection establishment method in FIG. 3. FIG. 3 describes the interaction flow chart of the electronic device 20, the Bluetooth device 10, and the server 30 using the Bluetooth connection establishment method. As shown in FIG. 3, the Bluetooth connection establishment method in the embodiment of the present application includes steps 301-307.

Step 301: receiving Bluetooth broadcast data sent by a Bluetooth device.

In one embodiment of the present application, after the Bluetooth device 10 turns on the Bluetooth function, the Bluetooth device 10 broadcasts Bluetooth broadcast data. The Bluetooth broadcast data includes the device information and binding identifier of the Bluetooth device 10. The device information of the Bluetooth device 10 is used to indicate the identity of the Bluetooth device 10. For example, the device information may include one or more of the product serial number (Serial Number, SN) and the media access control address (Media Access Control Address, MAC address) of the Bluetooth device 10. The binding identifier is used to indicate whether the Bluetooth device 10 is bound. It should be noted that the binding identifier can be set according to the needs of the user, and the first identifier is set to indicate that the Bluetooth device has been bound, and the second identifier is set to indicate that the Bluetooth device is not bound. For example, the preset field in the negotiation broadcast data is the identifier field, and the value of the identifier field can be the first identifier 11 or the second identifier 00, wherein the value of the identifier field is 11 indicating that the Bluetooth device is bound, and the value of the identifier field is 00 indicating that the Bluetooth device 10 is not bound.

It should be noted that, here, whether the Bluetooth device 10 is bound refers to whether the Bluetooth device 10 has previously established an association with any user, and the user here can be understood as a user account. Exemplarily, if the Bluetooth device 10 has previously established a successfully authenticated Bluetooth connection with an electronic device, the electronic device can send the device information, key, and information of the user account currently logged in by the electronic device to the server, so that the server can establish an association between the Bluetooth device 10 and the user account. After binding, the binding identifier in the Bluetooth broadcast data emitted by the Bluetooth device 10 will be set to the first identifier. At the same time, the Bluetooth device 10 will authenticate the subsequently established Bluetooth connection with the corresponding key. At this time, electronic devices that do not have the key will not be able to connect to the Bluetooth device 10.

It is understood that a corresponding button may be provided on the Bluetooth device 10, and the button may be a physical button, or a virtual button displayed on a touch screen. When the Bluetooth device 10 detects that the user has performed a preset operation on the button, the Bluetooth device 10 may enable the Bluetooth broadcast function.

Correspondingly, refer to Figure 4, which is a schematic diagram of a user interface 40 provided in an embodiment of the present application. In an embodiment of the present application, after the electronic device 20 detects that the user turns on the option 401 of the Bluetooth function on the user interface 40, the electronic device 20 can monitor the Bluetooth broadcast data sent by the surrounding Bluetooth devices, thereby receiving the Bluetooth broadcast data sent by the Bluetooth device 10.

In some other embodiments, the user may also trigger the electronic device 20 to listen to the Bluetooth broadcast data sent by the surrounding Bluetooth devices in other ways. For example, in some other embodiments, the electronic device 20 may also turn on the Bluetooth function and listen to the Bluetooth broadcast data sent by the surrounding Bluetooth devices after detecting that the user has opened a specific application (Application, APP). This embodiment of the application is not limited to this.

Step 302: Display the icon corresponding to the Bluetooth device.

After the electronic device 20 receives the Bluetooth broadcast data sent by the Bluetooth device, as shown in FIG. 4 , the electronic device 20 may display an icon 402 of the Bluetooth device 10 on the user interface 40 .

It should be noted that in actual application scenarios, the electronic device 20 may not receive Bluetooth broadcast data, or may receive Bluetooth broadcast data sent by one or more Bluetooth devices 10.

Correspondingly, when the electronic device 20 cannot receive Bluetooth broadcast data, the electronic device 20 may not display the icon of the Bluetooth device 10 .

When the electronic device 20 receives Bluetooth broadcast data sent by multiple Bluetooth devices 10 , the electronic device 20 may display icons 402 of the multiple Bluetooth devices 10 .

Step 303: In response to the user's operation on the above icon, a connection is established with the Bluetooth device according to the device information.

It should be noted that the current connection between the electronic device 20 and the Bluetooth device 10 is a temporary connection. If the Bluetooth device 10 fails to authenticate the key of the electronic device 20 subsequently, the temporary connection will be disconnected.

In one embodiment of the present application, the electronic device 20 may respond to a user clicking operation on the icon 402 (see FIG. 4 ) and establish a temporary connection with the Bluetooth device 20 corresponding to the icon 402 .

In one embodiment of the present application, the electronic device 20 also responds to the user's voice control operation to connect with the Bluetooth device 20 corresponding to the icon 402. For example, the user can control the electronic device 20 to connect to the Bluetooth device 20 corresponding to the icon 402 by voice "connect XX", or control the electronic device 20 to connect to the Bluetooth device 20 corresponding to the icon 402 by voice "connect the first one".

Step 304: If the binding identifier is the first identifier, a key acquisition request is sent to the server according to the information of the target user currently logging into the electronic device and the device information.

In one embodiment of the present application, after the electronic device 20 receives the Bluetooth broadcast data, it reads the value of the binding identifier from the preset field. If the binding identifier is the first identifier, it indicates that the Bluetooth device has been bound, and the electronic device 20 needs the corresponding key to establish a stable Bluetooth connection with the Bluetooth device. At this time, the electronic device 20 sends a key acquisition request to the server 30 based on the information of the target user currently logged in to the electronic device 20 and the device information of the Bluetooth device to be connected. The key acquisition request is used to instruct the server 30 to query the key associated with the device information from the key corresponding to the user group to which the target user belongs. In one embodiment of the present application, the user group includes the user's information, and the user group is associated with the key and the device information.

The target user refers to the user corresponding to the user account currently logged in by the electronic device 20, and the target user information refers to the information of the user account currently logged in by the electronic device 20, which can be a user name, account ID or other information, and this application does not limit this. For example, user A registers account XXX, the server assigns ID 1 to the account XXX, and user A logs in to the account XXX on the electronic device 20, then the target user information can be the account name "XXX" or ID 1.

In one embodiment of the present application, the electronic device 20 is logged into a target user account, and the electronic device can access the server 30 through the target user account. The information of the target user account is the information of the target user. For example, if user A logs into account XXX on the electronic device 20, the electronic device 20 can send a key acquisition request to the server 30 based on the information of account XXX and the device information of the Bluetooth device 10 obtained above.

After receiving the key acquisition request, the server 30 parses the target user information and the device information of the Bluetooth device 10, determines the user group to which the target user belongs, queries the key corresponding to the device information of the Bluetooth device 20 from the key corresponding to the user group, and feeds the key back to the electronic device 20. For example, after the key is encrypted, the encrypted key is carried in the response information sent to the electronic device 20.

In contrast, the server 30 may not find the key corresponding to the Bluetooth device 20. At this time, the server 30 may not respond to the electronic device 20, or the server 30 may feed back to the electronic device 20 a prompt message indicating that the key acquisition failed.

Step 305: Receive the key returned by the server and send the key to the Bluetooth device for authentication.

In one embodiment of the present application, after the electronic device 20 receives the response information returned by the server 30, it decrypts the encrypted key therein to obtain the key. For example, the server 30 queries the key corresponding to the device information of the Bluetooth device 20 from the key corresponding to the user group, encrypts the key with the public key, and sends the encrypted encrypted key to the electronic device 20. The electronic device 20 decrypts the encrypted key according to the private key corresponding to the public key to obtain the key. The electronic device 20 sends the key to the Bluetooth device 10, and the Bluetooth device 10 uses the key to authenticate the temporary connection established previously.

Step 306: After receiving the authentication success information returned by the Bluetooth device, the electronic device communicates with the Bluetooth device through connection.

In one embodiment of the present application, the Bluetooth device 10 may compare the received key with the preset key stored in the Bluetooth device 10. If the received key is consistent with the preset key, the Bluetooth device 10 may send authentication success information to the electronic device 20. If the received key is inconsistent with the preset key, the Bluetooth device 10 may send authentication failure information to the electronic device 20.

After the electronic device 20 receives the authentication success information returned by the Bluetooth device 10, the temporary connection becomes a formal connection, and the electronic device 20 will subsequently communicate with the Bluetooth device 10 through this connection.

In some embodiments, if the received key is inconsistent with the preset key, the Bluetooth device 10 can directly disconnect the temporary connection. After the electronic device 20 waits for a preset time, if it does not receive the authentication result returned by the Bluetooth device 10 and finds that the temporary connection has been disconnected, it is considered that the authentication has failed.

In the above embodiment of the present application, the electronic device 20 sends the key queried from the user group of the server 30 to the Bluetooth device 10 for verification, and after receiving the authentication success information returned by the Bluetooth device 10, the electronic device 20 communicates with the Bluetooth device 10. In this way, in the process of establishing a communication connection between the electronic device 20 and the Bluetooth device 10, encrypted authentication is used in the entire connection establishment process, which avoids interference with the connection by unauthenticated devices and allows users to be unaware of the encryption process, thereby improving the user experience.

In one embodiment of the present application, after step 305, the Bluetooth connection establishment method further includes:

Step 307: After receiving the authentication failure information returned by the Bluetooth device, the electronic device disconnects the connection established with the Bluetooth device and continues to monitor the Bluetooth broadcast data sent by other Bluetooth devices.

In one embodiment of the present application, the electronic device 20 disconnects the connection with the Bluetooth device 10 after receiving the authentication failure information returned by the Bluetooth device 10, thereby ensuring the communication security between the electronic device 20 and the Bluetooth device 10.

Subsequently, the electronic device 20 may continue to monitor the Bluetooth broadcast data sent by other Bluetooth devices.

In one embodiment of the present application, after receiving the authentication success information returned by the Bluetooth device 10, the above-mentioned Bluetooth connection establishment method also includes: the electronic device 20 sends a first instruction to the server 30 according to the key, device information and information of the target user.

It should be noted that the first instruction is used to instruct the server 30 to establish an association relationship between the key and the device information and the user group corresponding to the target user. The server 30 establishes an association relationship between the key and the device information and the user group corresponding to the target user according to the first instruction. In the above embodiment, after the server 30 establishes an association relationship between the key, the device information and the user group corresponding to the target user, the users (or user devices) in the user group can share the key and the device information, and all users of the entire user group, as long as one user binds the Bluetooth device for the first time, other users can directly obtain the key from the user group to connect to the Bluetooth device, which meets the scenario of multiple users using Bluetooth devices together, without the need for each user to repeatedly perform unbinding and binding operations. Under the premise of avoiding unauthenticated devices interfering with the connection, the user's operation process is further simplified, and the user does not need to unbind and rebind, which improves the user experience while speeding up the connection speed.

In one embodiment of the present application, the above-mentioned Bluetooth connection establishment method further includes: after receiving the authentication failure information, disconnecting the connection established with the Bluetooth device; and continuing to monitor the Bluetooth broadcast data.

It should be noted that after the Bluetooth device 10 determines that the key authentication has failed, it will return an authentication failure message to the electronic device 20. After receiving the authentication failure message, the electronic device will disconnect the connection previously established with the Bluetooth device 10. At the same time, it can continue to listen to the Bluetooth broadcast data sent by surrounding Bluetooth devices, including the Bluetooth broadcast data sent by the Bluetooth device 10.

It is understandable that before the electronic device 20 disconnects the connection, the Bluetooth device 10 may also disconnect the connection according to the authentication result.

It is understood that in one embodiment of the present application, when the Bluetooth device 10 determines that the key authentication fails, it disconnects from the electronic device 20 after a first preset time (such as 2 seconds) and resends the broadcast data. The Bluetooth device 10 records the number of authentication failures for the key sent by the same electronic device 20 for multiple consecutive times, and when the number of authentication failures reaches a preset number, it sleeps for a second preset time and resends the broadcast data. That is, here the electronic device 20 cannot monitor the Bluetooth broadcast sent by the Bluetooth device 10 within the second preset time.

In the above embodiment, when the electronic device 20 maliciously connects to the Bluetooth device 10 multiple times in a row, the Bluetooth device 10 can record the number of authentication failures for the key continuously sent by the electronic device 20, and when the number of authentication failures reaches a preset number, it will sleep for a second preset time and then resend the broadcast data, thereby ensuring the communication security between the Bluetooth device 10 and the electronic device 20.

In one embodiment of the present application, after disconnecting the connection established with the Bluetooth device 10, the above-mentioned Bluetooth connection establishment method further includes: displaying a first prompt message, the first prompt message is used to prompt that the Bluetooth connection fails. In one embodiment of the present application, after determining that the key authentication fails, the Bluetooth device 10 returns the authentication failure information to the electronic device 20. After the electronic device 20 disconnects the connection established with the Bluetooth device 10, or after the connection has been disconnected by the Bluetooth device 20, the electronic device 20 displays the first prompt message according to the authentication failure information returned by the Bluetooth device 10, and the first prompt message is used to prompt that the Bluetooth connection fails. In one embodiment of the present application, the first prompt message includes at least one of a text message notification, a voice notification, and a graphic mark. For example, after receiving the authentication failure information returned by the Bluetooth device 10, the electronic device 20 prompts the Bluetooth connection failure by displaying at least one of a text message notification, a voice notification, and a graphic mark, so that the user can be informed of the Bluetooth connection failure information in time, so that the user can perform subsequent Bluetooth connection operations.

In one embodiment of the present application, the above-mentioned Bluetooth connection establishment method also includes: in response to the operation of creating a new user group, obtaining the information of the selected user; generating a user group creation instruction based on the information of the selected user; and sending the user group creation instruction to the server 30, the user group creation instruction being used to instruct the server 30 to create a new user group based on the information of the selected user.

It is understandable that the above user group establishment process can be performed at any time, for example, before the user establishes a connection with the Bluetooth device for the first time, or after the connection is established, and this application does not impose any limitation on this.

Referring to FIG5 , a schematic diagram of a user group creation interface 50 in an embodiment of the present application is shown. The user group creation interface 50 includes a creation option 501. Referring to FIG5 , a user triggers the operation of creating a new user group by clicking the creation option 501. Referring to FIG6 , the electronic device 20 displays a list 502 in response to the user clicking the creation option 501. The list 502 includes information of at least one user. The electronic device 20 obtains the user information selected by the user in the list 502, generates a user group creation instruction, and sends the user group creation instruction to the server 30. The server 30 creates a new user group based on the information of the selected user, and associates the user group with the key sent by the electronic device 20 and the device information of the Bluetooth device 10. The users in the new user group created in the present application can share the key and connect to the Bluetooth device 10 by Bluetooth, and other users in the user group can directly obtain the key from the user group to connect to the Bluetooth device, which satisfies the scenario of multiple users using the Bluetooth device together.

In one embodiment of the present application, after receiving the authentication success information returned by the Bluetooth device, the Bluetooth connection establishment method further includes: associating the key and the device information and storing them in the memory of the electronic device 20.

In the present application, after successfully receiving the authentication success information returned by the Bluetooth device, the electronic device 20 stores the key and device information in association, so that the key can be obtained directly from the local without having to be obtained from the server, which can speed up the connection speed.

In one embodiment of the present application, the Bluetooth device 10 can also accept a reset operation, setting the binding identifier of the Bluetooth device 10 to the second identifier and clearing the above-mentioned key.

It can be understood that the reset operation can be triggered by the user operating a corresponding reset button on the Bluetooth device 10. For example, the Bluetooth device 10 is set with a reset button. When the Bluetooth device 10 detects that the user has performed a preset operation on the reset button, the binding identifier of the Bluetooth device 10 is set to the second identifier and the preset key is cleared. In this way, the Bluetooth device 10 can set the Bluetooth device 10 to be unbound according to the reset operation, which facilitates the binding connection of the Bluetooth device 10 with other electronic devices after unbinding. The reset operation can also be triggered by the user through a corresponding reset operation on the application of the electronic device 20. The application is the application corresponding to the Bluetooth device 10 and is used to control the Bluetooth device 10. It can be understood that at this time, the reset operation can be sent by the electronic device 20 to the server, and then sent by the server to the Bluetooth device. Alternatively, the reset operation can also be sent directly to the Bluetooth device by the electronic device 20.

Referring to Figure 7, a flowchart of a method for establishing a Bluetooth connection provided in another embodiment of the present application is shown. As shown in Figure 7, the method for establishing a Bluetooth connection in the embodiment of the present application includes steps 601-605.

Step 601: Receive Bluetooth broadcast data sent by a Bluetooth device.

Step 602: Display the icon corresponding to the Bluetooth device.

Step 603: In response to the user's operation on the above icon, a connection is established with the Bluetooth device according to the device information.

In the embodiment of the present application, steps 601-603 of FIG. 7 are the same as steps 301-303 of FIG. 3 . For the specific implementation contents of steps 601-603 of FIG. 7 , please refer to the implementation contents of steps 301-303 of the Bluetooth connection establishment method in FIG. 3 , which will not be repeated here.

Step 604: If the binding identifier of the broadcast data is the second identifier, the electronic device generates a key and sends the key to the Bluetooth device.

In one embodiment of the present application, after the electronic device 20 receives the Bluetooth broadcast data, it reads the value of the binding identifier from the preset field. If the binding identifier is the second identifier, it indicates that the Bluetooth device 10 is not bound and the electronic device 20 is connected to the Bluetooth device 10 for the first time. When the electronic device 20 establishes a connection with the Bluetooth device 10 for the first time, it automatically generates a key and sends the key to the Bluetooth device 10. For example, the electronic device 20 generates the key based on at least one of its own device information, the device information of the Bluetooth device 10, and the time information when the electronic device 20 receives the Bluetooth broadcast data. For another example, the electronic device 20 can generate the key based on a selected random number.

Step 605: After receiving the authentication success information returned by the Bluetooth device, the electronic device communicates with the Bluetooth device through connection.

In one embodiment of the present application, the Bluetooth device 10 receives the key sent by the electronic device 20, uses the key as a preset key, and directly sends the authentication success information to the electronic device 20. After receiving the authentication success information returned by the Bluetooth device 10, the electronic device 20 communicates with the Bluetooth device 10 through a connection.

In the above-mentioned embodiment of the present application, when it is determined that the Bluetooth device 10 is not bound, the Bluetooth device 10 does not need to compare the key with the preset key, and directly returns the authentication success information to the electronic device 20 to realize the communication between the electronic device 20 and the Bluetooth device 10, thereby simplifying the first connection process between the Bluetooth device 10 and the electronic device 20.

In another embodiment of the present application, when the Bluetooth device 10 is not bound, the Bluetooth device 10 may also send a key to the electronic device 10 after establishing a connection with the electronic device 10. After receiving the key, the electronic device 20 may feedback key reception information to the Bluetooth device 10. After receiving the key reception information, the Bluetooth device 10 may return authentication success information to the electronic device 20. After receiving the authentication success information returned by the Bluetooth device 10, the electronic device 20 communicates with the Bluetooth device 10 through the connection. That is to say, in the embodiment of the present application, the generator of the key and the key generation method are not limited.

8, which is a schematic diagram of the structure of a Bluetooth connection establishment device 100 provided in an embodiment of the present application. The Bluetooth connection establishment device 100 can be used to implement the above-mentioned Bluetooth connection establishment method.

Specifically, the Bluetooth connection establishing device 100 includes a receiving module 11 , a display module 12 , a connecting module 13 , and a requesting module 14 .

The receiving module 11 receives the Bluetooth broadcast data sent by the Bluetooth device. The Bluetooth broadcast data includes the device information and the binding identifier of the Bluetooth device 10. The binding identifier is used to indicate whether the Bluetooth device 10 is bound.

The display module 12 displays an icon corresponding to the Bluetooth device 10 .

The connection module 13 establishes a connection with the Bluetooth device 10 according to the device information in response to the user's operation on the icon.
