The Bluetooth master device scans to discover other Bluetooth devices (such as Bluetooth slave devices) around it. After the scan is complete, the Bluetooth master device displays the scanned Bluetooth slave devices. Then, the user selects a Bluetooth slave device (such as device B) for authentication and pairing, and establishes a Bluetooth connection between the master device (that is, device A) and the slave device (that is, device B) after successful pairing to transmit services data.

Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Among them, in the description of the embodiments of this application, unless otherwise specified, "/" means or means, for example, A/B can mean A or B; "and/or" in this article is only a description of associated objects The association relationship of indicates that there may be three kinds of relationships, for example, A and/or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. In addition, in the description of the embodiments of the present application, "plurality" refers to two or more than two.

Hereinafter, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of this embodiment, unless otherwise specified, "plurality" means two or more.

We know that the establishment of a Bluetooth connection needs to be based on device discovery and connection authentication. Among them, the device discovery is used for the master device to discover the slave devices that can be connected around. Connection authentication is used to ensure the security of Bluetooth communication.

Wherein, the master device is a device that initiates a Bluetooth connection, and the slave device is a Bluetooth device that can be discovered by the master device. It can be understood that a master device is relative to a slave device, and a terminal device can be used as a master device to discover a slave device and initiate establishment of a Bluetooth connection, or as a slave device.

Exemplarily, as shown in Figure 1, the master device can detect surrounding bluetooth devices (such as slave devices), and when the slave device is detected, record the information (such as media access control (media access control, MAC) address of the slave device ), and the ID of the detected slave device is displayed. When the user chooses to establish a Bluetooth connection with a certain slave device (such as slave device A), the master device and the slave device perform authentication pairing.

Among them, based on Bluetooth technology, the master device and the slave device can be decrypted through negotiation to establish a point-to-point connection. This process is called Bluetooth pairing. As an example, as shown in Figure 1, the pairing between the master device and the slave device (such as slave device A) can be performed through the following three steps:

Step 1: The master device and the slave device exchange authentication requirements and interaction capabilities.

Wherein, the interaction capability is an input/output capability (input/output, I/O) capability. The I/O capability determines the subsequent authentication method. Exemplarily, the I/O capability is NoInputNoOutput, DisplayOnly, NoInputNoOutput1, DisplayYesNo, KeyboardOnly or KeyboardDisplay.

Step 2: The master device and the slave device exchange public keys (public key).

Among them, the public key (public key) is used for the terminal device to calculate the key.

Step 3: The master device and the slave device perform authentication.

Exemplarily, the master device and the slave device may use the above-mentioned key for authentication based on a security management protocol (secure manager protocol, SMP). Among them, the SMP protocol is used to connect based on the logical link control and adaptation protocol (L2CAP) to realize pairing between the master device and the slave device, password transmission and other operations.

Exemplarily, the master device and the slave device may select a specific authentication method to perform authentication according to the authentication requirements of the peer end and its own authentication capability.

For example, if both the master device and the slave device support man-in-the-middle (MITM) authentication, the master device and the slave device can negotiate to generate serial codes (such as 6 numbers) and display them separately, so that users can compare Then confirm. For example, if the serial codes displayed by the two devices are consistent, the authentication passes; if the serial codes displayed by the two devices are inconsistent, the authentication fails. Alternatively, one device (such as a master device or a slave device) randomly generates a serial code (such as 6 numbers), and the other device displays a verification interface so that the user can assist authentication by entering the pairing code. For example, if the pairing code entered by the user is the same as If the above serial codes are consistent, the authentication will pass; if the pairing code input by the user is inconsistent with the above serial codes, the authentication will fail. Exemplarily, when the user inputs the pairing code, the device can synchronously transmit the pairing code input by the user to the peer device, and the peer device performs verification to achieve the purpose of authentication.

If the authentication of the master device and the slave device is successful, the master device and the slave device will perform subsequent pairing; if the authentication of the master device and the slave device fails, the pairing of the master device and the slave device will fail.

It can be seen that the conventional method for establishing a Bluetooth connection is relatively complicated and cumbersome for the user.

Moreover, with the diversified development of terminal technologies, the scope of a user's use of a terminal device has expanded from one terminal device to multiple terminal devices. For example, users can use multiple terminal devices to conduct cross-device services based on Bluetooth technology. This leads to problems in scenarios such as Bluetooth connection switching. For example, in the scenario where device A initiates the establishment of a Bluetooth connection with device B, and switches to device C initiating the establishment of a Bluetooth connection with device A, for users, based on conventional methods Usually, the following processes are required: the user triggers device A to discover the slave device → the user manually selects the discovered device B → the user performs connection authentication between device A and device B → the user triggers device C to discover the slave device → the user manually selects the discovered device A → The user authenticates the connection between device A and device C. The above-mentioned conventional method for establishing a Bluetooth connection is more complicated and cumbersome for the user to operate, and the user experience is poor.

In order to simplify the user's operation in the process of establishing a Bluetooth connection, the embodiment of the present application provides a method for establishing a Bluetooth connection. This method can share pairing information between terminal devices, for example, the first device shares pairing information with the second device. The second device directly establishes a Bluetooth connection with other devices (such as a third device) that have been paired with the first device without pairing. Wherein, the pairing information includes Bluetooth pairing information between the first device and other devices (such as the third device).

Based on the Bluetooth connection establishment method provided by the embodiment of the present application, for the third device, the third device only needs to be paired once (that is, paired with the first device), and other terminal devices (such as the second device) can be paired with the third device without pairing. The third device establishes a Bluetooth connection.

As an implementation manner, the first device may share the pairing information with the second device in a form of near-end sharing. For example, the first device may share the pairing information with a terminal device (such as the second device) that has established a communication connection with the first device.

Exemplarily, taking the first device as a smart phone, the second device as a tablet computer, and the third device as a Bluetooth headset as an example, as shown in (a) in FIG. 2 , the smart phone and the Bluetooth headset (( a) The device identified as A1) has been paired, and the tablet and the Bluetooth headset are not paired. After the smartphone shares the Bluetooth pairing information of the smartphone and the Bluetooth headset to the tablet computer in the form of near-end sharing, as shown in (b) in Figure 2, the paired device list of the tablet computer displays The headset (the device identified as A1 as shown in (b) in Figure 2) has been paired.

As another implementation manner, the first device may share the pairing information with the second device through the fourth device. Wherein, the fourth device may be a cloud-side device (such as a cloud server), or other terminal devices, which is not limited in this application.

As an example, take the first device as a smart phone, the second device as a tablet, the third device as a Bluetooth headset, and the fourth device as a cloud server. The first device and the second device log into the same cloud server account as an example, as shown in the figure As shown in 3, the tablet computer and the Bluetooth headset are not paired, the smartphone and the Bluetooth headset (the device marked as A1 as shown in Figure 3) have been paired, and the smartphone synchronizes the Bluetooth pairing information of the smartphone and the Bluetooth headset to the cloud server. After the tablet computer is synchronized from the cloud server to obtain the Bluetooth pairing information of the smartphone and the Bluetooth headset, the paired device list of the tablet computer shows that the tablet computer and the Bluetooth headset (the device identified as A1 as shown in Figure 3) have been paired .

In some embodiments of the present application, the first device supports sharing the pairing information of one or more devices that have been paired with it to the second device according to the actual needs of the user.

In some other embodiments of the present application, the first device supports sharing the pairing information of all devices that have been paired with it to the second device.

Taking the example shown in Figure 2 and Figure 3 as an example, a smart phone (that is, the first device) and a Bluetooth headset (as shown in (a) in Figure 2 and a device identified as A1 in Figure 3) and a Bluetooth mouse (as shown in Figure 2 (a) in (a) and the device identified as A2 shown in Figure 3) have been paired. When the smart phone shares the pairing information with the tablet computer (that is, the second device), the smart phone shares the Bluetooth pairing information with the Bluetooth headset, And the Bluetooth pairing information with the Bluetooth mouse is shared with the tablet computer. The tablet computer (that is, the second device) displays the tablet computer and the Bluetooth headset in the paired device list of the tablet computer according to the pairing information shared by the smartphone (as shown in (b) in Figure 2 and the device identified as A1 in Figure 3 ) and the Bluetooth mouse (as shown in (b) in Figure 2 and the device identified as A2 in Figure 3) have been paired.

In the embodiment of the present application, the terminal device supports Bluetooth communication or has a Bluetooth communication function.
