Detailed ways

Embodiments of the present application are described below in conjunction with the accompanying drawings.

The Bluetooth pairing method provided in the embodiment of the present application is applicable to a pairing process between devices in Bluetooth communication. First, the pairing process is introduced.

In Bluetooth communication, before two devices conduct Bluetooth communication for the first time, they need to go through a pairing process first. After the pairing of the two devices is completed, information such as the Bluetooth device address (BD_ADDR) and key are stored in the device, so that Bluetooth communication can be performed. Subsequently, if the Bluetooth address, key and other information stored in the two devices are not cleared, when the Bluetooth communication is performed again, the two devices can send a Bluetooth connection request according to the Bluetooth address, and there is no need to perform the pairing process again.

Exemplarily, FIG. 1 is a schematic diagram of a scenario of Bluetooth communication. As shown in FIG. 1 , both the electronic device 100 and the Bluetooth device 200 support the Bluetooth function, and the electronic device 100 and the Bluetooth device 200 can perform Bluetooth communication.

Wherein, the types and names of the electronic device 100 and the Bluetooth device 200 are not limited. For example, examples of some electronic devices are: mobile phones, tablet computers, notebook computers, handheld computers, wearable devices, smart screens, teaching equipment, Internet of Things (internet of things, IOT) devices, or smart home (smart home) wireless terminals, etc. Optionally, the electronic device 100 has a display screen. Examples of some bluetooth devices are: bluetooth earphones, bluetooth speakers, bluetooth stylus and so on.

For convenience of description, the embodiment of the present application takes the electronic device 100 as a mobile phone and the Bluetooth device 200 as a Bluetooth headset as an example for description.

Next, the message flow in the pairing process will be described. For ease of understanding, the pairing process may include a device discovery phase and a pairing phase. In the device discovery phase, the electronic device can discover a Bluetooth device that can be paired, and exchange relevant information required in the pairing phase with the Bluetooth device, for example, the Bluetooth address of the Bluetooth device. In the pairing phase, the electronic device and the Bluetooth device can exchange information such as keys for subsequent Bluetooth communication.

FIG. 2 is a diagram of message interaction between the Bluetooth device and the electronic device in FIG. 1 during the pairing process. As shown in Figure 2, the pairing process between devices in Bluetooth communication may include:

S21. The Bluetooth device enters a pairing mode in response to the user's operation on the Bluetooth device.

Specifically, the user needs to operate the Bluetooth device so that the Bluetooth device enters a pairing mode. When the Bluetooth device is in the pairing mode, it can search for an inquiry request (inquiry request) sent by the electronic device, and reply an inquiry response (inquiry response) to the electronic device, so that the electronic device can discover the Bluetooth device. Wherein, when the usage status of the Bluetooth device is different, the user may operate the Bluetooth device differently.

Optionally, in an implementation manner, it is a scenario in which the Bluetooth headset is first unpacked and used. As shown on the left side of FIG. 3A , the Bluetooth headset includes a case cover 201 and a case body 202 . The bluetooth headset has never been used out of the box after leaving the factory. As shown on the right side of FIG. 3A , when the Bluetooth headset is unpacked and used for the first time, the Bluetooth headset can be triggered to enter a pairing mode. Correspondingly, the Bluetooth headset enters the pairing mode in response to the user's operation.

Optionally, in another implementation manner, it is a scenario where the Bluetooth headset is not used for the first time. As shown on the left side of FIG. 3B , the Bluetooth headset has been used out of the box, and Bluetooth communication has been performed with at least one electronic device. As shown on the right side of Figure 3B, when the Bluetooth headset needs to perform Bluetooth communication with an electronic device that has never been paired, or when performing Bluetooth communication with an electronic device that has been paired in history but needs to be re-paired, the user can press the box body 202 The physical button 203 on the keyboard triggers the Bluetooth headset to enter pairing mode. Correspondingly, the Bluetooth headset enters the pairing mode in response to the operation of pressing the physical button 203 by the user.

It should be noted that the embodiment of the present application does not limit the name of the pairing mode. For example, the pairing mode may also be called a pairing state or an inquiry scan (inquiry scan) state.

S22. The electronic device sends an inquiry request (inquiry request). Correspondingly, the Bluetooth devices in the pairing mode around the electronic device can scan the query request and receive the query request.

Specifically, after the electronic device turns on the bluetooth function, it can enter an inquiry state and send an inquiry request to surrounding devices. Correspondingly, if the surrounding Bluetooth devices are in the pairing mode, the inquiry request can be scanned, and an inquiry response (inquiry response) can be returned to the electronic device, so that the electronic device can discover the Bluetooth device.

Wherein, the execution order of S21 and S22 is not limited. For example, the user first triggers the Bluetooth headset to enter the pairing mode by pressing a physical button on the Bluetooth headset box, and then the electronic device turns on the Bluetooth function, that is, first executes S21 and then executes S22. For another example, the electronic device first turns on the bluetooth function, and then the user opens the box and uses the bluetooth earphone for the first time to trigger the bluetooth earphone to enter the pairing mode, that is, first execute S22 and then execute S21.

Wherein, the query request includes the bluetooth address of the electronic device, and the bluetooth address can refer to related content in the bluetooth protocol, which will not be repeated here.

Optionally, the electronic device may send the query request according to the first cycle. Optionally, the Bluetooth device in the pairing mode may scan for query requests according to the second cycle. Optionally, the first period and the second period may be the same or different.

S23. The Bluetooth device sends an inquiry response (inquiry response) to the electronic device. Correspondingly, the electronic device receives the inquiry response sent by the Bluetooth device.

Wherein, the query response includes the Bluetooth address of the Bluetooth device.

Specifically, when the Bluetooth device in the pairing mode scans the query request sent by the electronic device, it can return a query response to the electronic device according to the Bluetooth address of the electronic device in the query request, so that the electronic device can discover the Bluetooth device and continue to communicate with the electronic device. The device goes through the subsequent pairing process.

It should be noted that the stage of discovering devices includes but not limited to S21-S23. For example, in the device discovery phase, the electronic device and the Bluetooth device can also obtain at least one of the following information through message interaction: the device name of the Bluetooth device, the device supported feature information of the electronic device, and the device information of the Bluetooth device. Support feature information. Wherein, the device support feature information may also be referred to as capability information, and reference may be made to the content about device features in the Bluetooth protocol, which will not be repeated here.

Through the device discovery stage, the electronic device can discover the Bluetooth devices around it that can be paired. Exemplarily, FIG. 4A shows a schematic interface of an electronic device in a device discovery stage. As shown in FIG. 4A , the bluetooth main interface 40 of the mobile phone includes a switch control 41 of the bluetooth function, a switch control 42 of open detection, a "device name" tab 43, a "received file" tab 44, and a paired

device

45 and 46 devices available. It can be known from the "device name" tab 43 that the name of the mobile phone is "mobile phone 2". Paired devices 45 shows devices that have been successfully paired with phone 2 in history, eg, phone 1 . The available devices 46 display currently pairable devices discovered by the mobile phone 2, for example, Bluetooth headsets. As shown in FIG. 4A , the user can click on the Bluetooth headset in the available devices 46 to pair the mobile phone 2 with the Bluetooth headset. Correspondingly, the mobile phone 2 starts the pairing stage in the pairing process in response to the user's operation.

Optionally, before the mobile phone 2 and the Bluetooth headset are paired, a prompt message may also be displayed. Exemplarily, after the user clicks the Bluetooth headset in the available devices 46 in FIG. 4A , the changes of the Bluetooth main interface 40 can be seen in FIG. 4B . As shown in FIG. 4B , the mobile phone 2 pops up a pairing window 47 in the Bluetooth main interface 40 . The user operates by viewing the prompt information in the pairing pop-up window 47 . For example, the prompt information includes: "To pair with the following device: Bluetooth headset". The pairing pop-up window 47 also includes a cancel button and a pairing button. The user can click the pairing button 48 to make the mobile phone 2 pair with the Bluetooth headset. Correspondingly, in response to the user's operation of clicking the pairing button 48, the mobile phone 2 executes the message flow of the pairing phase, see S24 for details.

S24. The electronic device sends a pairing request (pairing request) to the Bluetooth device. Correspondingly, the Bluetooth device receives the pairing request sent by the electronic device.

S25. The Bluetooth device sends a pairing response (pairing response) to the electronic device. Correspondingly, the electronic device receives the pairing response sent by the Bluetooth device.

Specifically, in the pairing phase, the electronic device may send a pairing request to the Bluetooth device according to the Bluetooth address of the Bluetooth device, and the Bluetooth device may send a pairing response to the electronic device according to the Bluetooth address of the electronic device, and the pairing request and the pairing response are used to exchange configuration information, Configuration information is used to determine the pairing method and distribute keys.

Optionally, the configuration information may include the input and output capabilities of the electronic device. Different electronic devices have different types, different hardware configurations, and different input and output capabilities. For example, the input/output capability may indicate at least one of the following: whether the electronic device can input, an input method when the electronic device can input, whether the electronic device can display, and so on.

This implementation is applicable to a scenario where only the first electronic device, the second electronic device and the Bluetooth device exist in the environment.
