Fig. 3 is a schematic flowchart of a bluetooth connection control method according to an embodiment of the present application. As shown in fig. 3, the bluetooth connection control method provided by the embodiment of the application includes:

101, after the first bluetooth device opens the box, sending BLE broadcast to the first electronic device. The BLE broadcast contains identification information and status information of the first bluetooth device.

102, the first bluetooth module of the first electronic device detects a BLE broadcast transmitted by the first bluetooth device.

103, the first bluetooth module determines that the first bluetooth device is a historical bluetooth device according to the identification information carried by the BLE broadcast.

104, the first Bluetooth module determines that the first Bluetooth device is in a first box opening state according to state information carried by BLE broadcasting, wherein the first box opening state indicates that the time length after box opening is smaller than a set threshold value.

The first bluetooth module determines to adjust the parameter information of the page scanning operation 105.

The first bluetooth device may include left and right headsets. In an actual implementation scenario, after the first bluetooth device opens the box, a connection between the left and right headphones needs to be established first, and the process needs to be about 300-500 milliseconds. After the left and right earphone connection is established, the Bluetooth connection can be established with the surrounding first electronic equipment in a connectable state. It should be noted that, in the process of establishing connection between the left and right earphones, the first bluetooth device also performs the following service in parallel, that is, sends BLE bluetooth broadcast to the first electronic device. The BLE bluetooth broadcast may be used to notify the first electronic device that the first bluetooth device is in a connectable state.

Based on the above-mentioned real scenario, in the embodiment of the present application, the target information of the first bluetooth device may be added in the BLE bluetooth broadcast sent by the first bluetooth device. Furthermore, the first bluetooth module of the first electronic device may receive the BLE bluetooth broadcast by using a time difference between connection between the left and right earphones of the first bluetooth device, and perform condition judgment on the first bluetooth device based on target information carried in the BLE bluetooth broadcast.

After determining that the first bluetooth device satisfies the first condition, the first bluetooth module may determine to adjust the parameter information of the page scanning operation. By adjusting the parameter information of the paging scanning operation, the response speed of the first electronic equipment to the paging request of the first Bluetooth equipment can be improved, the Bluetooth connection speed between the first electronic equipment and the first Bluetooth equipment is further improved, and the user experience is improved. Moreover, it can be understood that the above process of receiving the bluetooth broadcast and performing the condition judgment is performed by using the time difference of establishing the connection between the left and right earphones of the first bluetooth device, so that multiplexing of the same time period can be realized, and additional time consumption is avoided.

The method for determining that the first bluetooth device satisfies the first condition by using the first bluetooth module is described in detail below.

In the embodiment of the present application, the target information carried in the BLE bluetooth broadcast may include identification information and status information of the first bluetooth device. Wherein the identification information can be used to uniquely identify the bluetooth device. The state information may be used to characterize the current state of the first bluetooth device, including the first open box state, etc. In the embodiment of the application, the first box opening state refers to a state that the time length after box opening is smaller than a set threshold value, and can be colloquially understood as a state of just opening the box.

According to this implementation manner, after the first bluetooth module of the first electronic device receives the BLE bluetooth broadcast, first, identification information of the first bluetooth device carried in the first bluetooth module may be read.

In a practical scenario, as shown in fig. 4, BLE bluetooth broadcast packet Data may include two parts, valid Data signifiant and invalid Data non-signifiant. Wherein the signalization part may further comprise a number of broadcast data units AD structures. Each AD Structure may include two parts of Length and Data. Wherein Length is used to represent the Length of the own broadcast data unit. Data may further include two parts of Data Type AD Type and Data content AD Data.

Based on the above scenario, in the embodiment of the present application, the identification information may be added to, for example, the header position of the BLE bluetooth broadcast, or the identification information may also be added to the first target field AD Structure X of the BLE bluetooth broadcast packet. AD Structure X may be any field of the first bluetooth device pre-protocol with the first electronic device, for example, may be a field with AD Type manufacturer specific. The AD data of the manufacturer specific field may include two parts, a manufactor ID and an additional data, and the identification information of the embodiment of the present application may be added to the additional data part, for example.

Further, the identification information may be any information capable of uniquely identifying the first bluetooth device. In an alternative implementation, the identification information may be a BLE bluetooth address of the first bluetooth device. In another alternative implementation, the identification information may be a random number sequence that is pre-agreed with the first bluetooth device and the first electronic device.

The first Bluetooth module can judge whether the first Bluetooth device is a historical Bluetooth device or not according to the read identification information. A historical bluetooth device refers to a bluetooth device that has established a bluetooth connection with a first electronic device.

Specifically, the first bluetooth module may store reference identification information of the historical bluetooth device. After the identification information of the first bluetooth device is read, the identification information may be compared with reference identification information of the historical bluetooth device. According to the comparison result, if the comparison result is consistent, the first Bluetooth device can be determined to be a historical Bluetooth device.

Taking the identification information of the first bluetooth device as a BLE bluetooth address as an example for illustration. At this time, the reference identification information of the history bluetooth device may be a reference classical bluetooth address. Because BLE bluetooth address and classical bluetooth address belong to different bluetooth protocols, can't directly compare between the two. Therefore, in the embodiment of the present application, the address mapping relationship may be stored in the first bluetooth module in advance. The address mapping may be used to specify the mapping of BLE bluetooth addresses to classical bluetooth addresses. The mapping relationship may be set by the vendor's own negotiation, e.g., may be set such that the BLE bluetooth address is the same as the classical bluetooth address, or different.

Based on the above, the first bluetooth module may determine, according to the preset address mapping relationship, a reference BLE bluetooth address corresponding to a reference classical bluetooth address of the historical bluetooth device. Further, the first bluetooth module may compare the reference BLE bluetooth address with a BLE bluetooth address of the first bluetooth device. If the comparison is consistent, then the first Bluetooth device may be determined to be a historical Bluetooth device.

Under the condition that the first Bluetooth module determines that the first Bluetooth device is the historical Bluetooth device according to the identification information, the first Bluetooth device can be considered to have high possibility of establishing Bluetooth connection with the first electronic device.

Then, the first bluetooth module may continue to read the state information of the first bluetooth device carried in the BLE bluetooth broadcast.

Specifically, the status information may be set in a second target field of the BLE bluetooth broadcast message, for example. The second target field may be any field of the first bluetooth device's pre-protocol with the first electronic device. The specific data content of the status information, and the meaning characterized by each data content, may be determined by a predetermined protocol of the first bluetooth device with the first electronic device.

The first bluetooth module can judge whether the first bluetooth device is in a first box opening state, namely a box opening state. If the first Bluetooth device is in the as-opened box state, it is indicated that the first Bluetooth device has a high probability of being connected to the first electronic device.

Further, it is determined that the first bluetooth device satisfies the first condition.

After determining that the first bluetooth device meets the first condition, further, the first bluetooth module may determine to adjust parameter information of the page scanning operation.

In one possible implementation, the parameter information for page scanning operation may include a scanning rate.

The scan rate may be used to characterize the size of the interval between two page scan operations. The greater the scanning rate, the smaller the interval between two page scan operations, the faster the page request is heard, but at the same time the greater the power consumption. Based on this, upon determining that the first bluetooth device satisfies the first condition, the first bluetooth module may determine to adjust the current scanning rate of the page scanning operation to the target scanning rate. Wherein the target scan rate is higher than the current scan rate.

In an actual implementation scenario, the scan rate may include several gears such as R0, R1, R2, etc. according to the current bluetooth protocol standard. The gear R1 may further include a plurality of gears including Fast R1, medium R1 and Low R1. Correspondingly, the gear R2 can also comprise a plurality of gears of Fast R2 and Slow R2. Each gear corresponds to a particular scan rate value. The scanning rate corresponding to R0 is the largest, and the scanning rate corresponding to R2 is the smallest.

Based on the above, in the embodiment of the present application, for example, if the gear of the current scanning rate is Medium R1, the gear of the adjusted target scanning rate may be Fast R1.

In another possible implementation, the parameter information for page scanning operation may include traffic priority.

For the first electronic device, there may be multiple bluetooth services to be performed in the same time period, which may include page scanning, bluetooth data transmission, and so on, for example. In an actual execution scenario, in order to enable multiple bluetooth services to be executed in order, different priorities may be generally set for different bluetooth services, and then, each bluetooth service may be executed sequentially according to the order of the priorities from high to low. Based on this, in the embodiment of the present application, after determining that the first bluetooth device meets the first condition, the current service priority of the page scanning operation may be adjusted to the target service priority. Wherein the target service priority is higher than the current service priority.

By adjusting the service priority, the page scanning operation can be executed preferentially compared with other Bluetooth services, so that the first electronic device can respond to the paging request more quickly, and the Bluetooth connection speed between the first electronic device and the first Bluetooth device is improved.

In yet another possible implementation, the parameter information of the page scanning operation may include both the scanning rate and the traffic priority. In this implementation, after determining that the first bluetooth device meets the first condition, the first bluetooth module of the first electronic device may simultaneously adjust the current scanning rate of the page scanning operation to the target scanning rate, and adjust the current traffic priority of the page scanning operation to the target traffic priority.

Through the implementation mode, the paging response speed of the first electronic equipment can be improved from two aspects simultaneously, and the Bluetooth connection speed between the first electronic equipment and the first Bluetooth equipment is improved more efficiently.

According to the technical scheme provided by the embodiment of the application, the first electronic equipment can judge the condition of the first Bluetooth equipment, and when the first Bluetooth equipment is determined to be the history Bluetooth equipment which is connected once and is in the just-opened box state, the parameter information of the paging scanning operation can be determined to be adjusted, so that the paging response speed can be increased, and the Bluetooth connection speed is further improved. In addition, the parameter adjustment operation is based on the premise that the first Bluetooth device meets the specific condition, so that unnecessary power consumption can be prevented from being increased, and the Bluetooth connection speed and the power consumption can be realized.

The device information to be connected may be set in a third target field of the BLE bluetooth broadcast message, for example.

Through the technical scheme, the judgment of the first Bluetooth device can be more reliably realized, and the equipment connected with the first Bluetooth device is ensured to be the first electronic device, so that the first electronic device is prevented from carrying out unnecessary operation, and the operation resource is saved.

In another embodiment of the present application, the first electronic device may further include a second bluetooth module in addition to the first bluetooth module.

Fig. 8 is another schematic flowchart of a bluetooth connection control method according to an embodiment of the present application. As shown in fig. 8, the bluetooth connection control method provided by the embodiment of the application may include:

after the first bluetooth device opens the box, 401, a BLE broadcast is sent to the first electronic device. The BLE broadcast contains identification information and status information of the first bluetooth device.

402, a first bluetooth module of a first electronic device detects a BLE broadcast transmitted by the first bluetooth device.

403, the first bluetooth module reads the first flag bit.

404, the first bluetooth module determines whether the parameter information of the page scanning operation is in an adjustable state according to the first flag bit. If yes, go to step 405, otherwise, go to step 411.

In the embodiment of the application, the first flag bit can be set in the first electronic device. The first flag may be set to different values, which may be used to characterize different states of the parameter information of the page scanning operation.

For example, the first flag may have a first target value and a second target value. The first target value may be used, for example, to indicate that the parameter information for page scanning operation is in an adjustable state, and the second target value may be used, for example, to indicate that the parameter information for page scanning operation is in a non-adjustable state.

In one possible implementation manner, the first target value may be 1, for example, and the second target value may be 0, for example. The application is not limited in this regard.

After detecting the BLE broadcast sent by the first Bluetooth device, the first Bluetooth module can read the first flag bit first, and determine whether the parameter information of the paging scanning operation is in an adjustable state according to the first flag bit. Under the condition that the Bluetooth module is in the adjustable state, the first Bluetooth module can further execute the subsequent procedure to judge the identification information and the state information carried by the BLE broadcast. Otherwise, the first bluetooth module may directly end the current method flow.

405, the first bluetooth module determines, according to the identification information carried by the BLE broadcast, whether the first bluetooth device is a historical bluetooth device. If yes, step 406 is performed, otherwise step 411 is performed.

406, the first bluetooth module determines whether the first bluetooth device is in a first box opening state according to state information carried by BLE broadcast, wherein the first box opening state indicates that the time length after box opening is smaller than a set threshold value. If yes, step 407 is performed, otherwise step 411 is performed.

The first bluetooth module determines 407 to adjust the parameter information of the page scanning operation.

The first bluetooth module determines 408 whether a bluetooth connection request of the first bluetooth device is detected within a preset time period. If yes, go to step 409, otherwise, go to step 410.

409, the first bluetooth module recovers parameter information of the page scanning operation.

410, the first bluetooth module recovers the parameter information of the page scanning operation, and changes the first flag bit to a second target value, where the second target value is used to indicate that the parameter information is in an unadjustable state.

In view of the fact that the power consumption is increased by improving the parameter information such as the scanning rate of the page scanning operation, in the embodiment of the present application, in order to avoid unnecessary power consumption overhead, a time period may be preset, and the value of the preset time period may be used to specify the maximum maintenance duration of the target parameter information after the parameter information of the page scanning operation is adjusted to the target parameter information.

After the adjustment of the paging scanning operation parameter information is completed, the first bluetooth module may determine whether a bluetooth connection request of the first bluetooth device is detected within a preset period of time. The value of the preset time period can be flexibly set according to the actual scene, and can be 10S for example.

If it is determined that the bluetooth connection request of the first bluetooth device is detected within the preset time period, the bluetooth connection with the first bluetooth device can be completed, and the end of the bluetooth connection process is confirmed. At this time, to avoid increasing power consumption, the first bluetooth module may restore the parameter information of the page scanning operation, and adjust the parameter information back to the original value.

Conversely, if it is determined that the bluetooth connection request of the first bluetooth device is not detected within the preset time period, it may be determined that the first bluetooth device does not currently have a bluetooth connection requirement with the first electronic device. At this time, to avoid increasing power consumption, the first bluetooth module may also restore the parameter information of the page scanning operation, and adjust the parameter information back to the original value.

Further, for the case that the bluetooth connection request of the first bluetooth device is not detected within the preset period of time, the first bluetooth module may further change the first flag bit to the second target value after recovering the parameter information of the page scanning operation. By the technical means, the paging scanning operation parameter information can be locked, so that the paging scanning operation parameter information is in an unadjustable state. Then, after the first electronic device receives the BLE broadcast of the first bluetooth device again, the current method flow can be ended according to the first flag bit, and the identification information, the state information and the like contained in the first flag bit are not judged any more, so that unnecessary operation is avoided, and operation resources and power consumption are saved.

Furthermore, after the first bluetooth module changes the first flag bit into the second target value, the first bluetooth module can start timing, and after determining that the timing duration exceeds the set threshold, the first flag bit can be changed back to the first target value, so as to realize "unlocking" of the parameter information of the page scanning operation. After that, after the first electronic device receives the BLE broadcast of the first bluetooth device again, the method flow of the present application may be executed normally, and the identification information, the status information, etc. included in the BLE broadcast may be determined. The value of the set threshold can be flexibly set, for example, 30 minutes. Thus, it is possible to avoid affecting the normal bluetooth connection between the first electronic device and the first bluetooth device.

Step 411, the current flow is ended.

In the above technical scheme, the "locking" and "unlocking" of the parameter information of the page scanning operation can be realized by setting the first flag bit. Through the technical scheme, the first electronic equipment can be prevented from frequently responding to BLE broadcasting of the first Bluetooth equipment and frequently adjusting the parameter information of the paging scanning operation under a specific scene (such as a scene that a user unconsciously carries out frequent box opening and closing on the first Bluetooth equipment), and the waste of operation resources and power consumption is avoided.
