Based on the bluetooth device provided by any of the above embodiments, the present disclosure also provides a pairing method for the bluetooth device.

First, a bluetooth communication protocol is briefly described, and when bluetooth communication is performed between each pair of devices, one device is a master device, and the other device is a slave device. During communication, the main terminal equipment initiates a pairing request, and after pairing is successful, namely a link is established successfully, the two parties can transmit data in a short distance.

Based on the above bluetooth communication principle, the present disclosure provides a pairing method for bluetooth devices, which is applied to the bluetooth devices with ultrasonic communication devices as shown in fig. 1 and fig. 2. A pairing method of bluetooth devices shown with reference to fig. 3 according to an exemplary embodiment may include the steps of:

in step 31, broadcasting first bluetooth information of the local terminal bluetooth device and receiving second bluetooth information of the opposite terminal bluetooth device through the ultrasonic communication device;

in the embodiment of the present disclosure, the local-end bluetooth device may broadcast its own bluetooth information, that is, first bluetooth information, through the built-in ultrasonic communication apparatus, and receive the opposite-end bluetooth information, that is, second bluetooth information, sent by the opposite-end bluetooth device.

In this disclosure, the bluetooth information of the bluetooth device at least includes: a unique identification of the bluetooth communication device, such as a Media Access Control (MAC) address of bluetooth.

In the embodiment of the present disclosure, the role of the local-end bluetooth device in bluetooth communication may be a master device that initiates a pairing request, or may be a slave device that receives a pairing request.

In step 32, generating a universally unique identifier UUID according to the first bluetooth information and the second bluetooth information;

taking the bluetooth information as the bluetooth MAC address as an example, in the present disclosure, a Universal Unique Identifier (UUID) may be generated according to the MAC address of the local bluetooth device and the MAC address of the peer bluetooth device, so as to be used as a check code in a subsequent bluetooth device pairing process.

In this disclosure, in combination with the role of the local bluetooth device in bluetooth communication, and when the local bluetooth device is the master device, the user selects the time of the target bluetooth device, the implementation manner of step 12 may include at least the following three types:

in the first mode, after a user selects a target Bluetooth device, a target UUID is generated, and the method is suitable for an application scene in which a local end Bluetooth device is a main end device.

Referring to fig. 4, which is a flow chart illustrating another pairing method for bluetooth devices according to an exemplary embodiment, the step 32 may include:

in step 321, determining a target bluetooth device from two or more peer bluetooth devices according to a selection result of a user;

in the embodiment of the disclosure, the local bluetooth device may receive the second bluetooth information sent by two or more other bluetooth devices at the same time. The local terminal bluetooth device can display the second bluetooth information of the plurality of peer terminal bluetooth devices in a preset application interface in a list form, so that the local terminal user can select a device which is desired to be connected, namely the target bluetooth device.

In an exemplary application scenario, assuming that the local-end bluetooth device is a mobile phone a, the bluetooth information broadcasted by the bluetooth headset B, the mobile phone C, and the notebook computer D is received at a certain time, the bluetooth information of each peer-end bluetooth device may be displayed in a display interface, and the trigger information of the user selecting the target bluetooth device is sensed, for example, when the local-end touch screen displays the interface, the preset action information of the user is sensed, and the target bluetooth device and the MAC address are determined based on the preset action information.

In step 322, a target UUID is generated according to the MAC address of the target bluetooth device and the MAC address of the local bluetooth device.

In this disclosure, after determining the MAC address of the target bluetooth device, the local bluetooth device may generate a target UUID according to the MAC address of the local bluetooth device and the MAC address of the target bluetooth device.

In the second mode, before the user selects the target Bluetooth device, the UUID is generated, and the UUID list is obtained. The method is suitable for application scenes that the local terminal Bluetooth device is a slave terminal device.

Referring to fig. 5, which is a flow chart illustrating another pairing method for bluetooth devices according to an exemplary embodiment, the step 32 may include:

in step 32-1, generating a UUID according to the MAC address of each peer bluetooth device and the MAC address of the home bluetooth device;

the local bluetooth device may receive second bluetooth information, such as a bluetooth MAC address, sent by one or more peer bluetooth devices via ultrasonic waves within a period of time. The home terminal bluetooth device still takes the mobile phone a as an example, and in the embodiment of the present disclosure, the mobile phone a may generate a UUID each time the MAC address of an opposite terminal bluetooth device is received. Or counting MAC addresses of a plurality of opposite-end Bluetooth devices received by ultrasonic waves within a period of time, and then calculating UUIDs one by one.

In step 32-2, each UUID is associated with corresponding second bluetooth information, and a UUID list is generated.

In this disclosure, the local bluetooth device may associate one or more UUIDs generated in step 32-1 with corresponding second bluetooth information to form a UUID list. The UUID list includes: the corresponding relationship between the second bluetooth information and the UUID is shown in the following table one:

watch 1

In the first table, the second bluetooth information of the peer bluetooth device may include: a device-friendly name that facilitates user identification, and may also include information such as the type of device.

And in the third mode, before the user selects the target Bluetooth equipment, a UUID list is generated, and then the target UUID corresponding to the second Bluetooth information of the equipment is selected according to the target Bluetooth equipment selected by the user, so that the method is suitable for the application scene in which the local end Bluetooth equipment is the main end equipment.

Referring to fig. 6, a flowchart of another pairing method for bluetooth devices according to an exemplary embodiment is shown, on the basis of the embodiment shown in fig. 5, after step 32-2, step 32 may further include:

in step 32-3, the target UUID selected by the user from the UUID list is determined.

In this embodiment of the present disclosure, when the local-end bluetooth device is a master device, the user may select a target bluetooth device to be connected, such as the bluetooth headset B, based on the UUID list generated by the local-end bluetooth device, and further determine a target UUID, that is, the UUID1, from the first table.

According to the embodiment of the disclosure, before the user selects the target Bluetooth device, the UUID corresponding to each opposite-end Bluetooth device is firstly calculated, then when the target Bluetooth device is selected, the target UUID can be directly selected from the generated UUID list, and in the subsequent process of requesting Bluetooth pairing, due to the fact that the time for waiting for calculating the UUID in real time is avoided, the pairing efficiency can be improved.

In step 33, performing bluetooth pairing with the peer bluetooth device based on the UUID;

in the disclosure, after determining the target bluetooth device and the corresponding target UUID, the local end bluetooth device may perform bluetooth pairing with the target bluetooth device based on the target UUID.

According to the principle of the bluetooth communication technology, if the roles of the local bluetooth devices in bluetooth communication are different, the implementation of step 33 is also different, and the following two cases may be included:

in the first case, the local Bluetooth device is the master device

Referring to fig. 7-1, which is a flowchart illustrating another pairing method for bluetooth devices according to an exemplary embodiment, the step 33 may include the steps of:

in step 331, sending, by the ultrasonic communication apparatus, pairing request information carrying the target UUID, so that the target bluetooth device responds according to whether the target UUID is generated after receiving the request information;

in this disclosure, it is still assumed that the local bluetooth device is a mobile phone a, and the target bluetooth device selected by the user is a bluetooth headset B.

The handset a transmits pairing request information including the UUID1 in addition to the request content information in a broadcast manner through its own ultrasonic communication apparatus.

In step 332, if the ultrasonic communication apparatus receives the pairing confirmation information sent by the target bluetooth device, it is determined that the pairing is successful.

After the mobile phone A broadcasts the pairing request information, the ultrasonic communication device is enabled to be in a monitoring state, information broadcasted by surrounding Bluetooth equipment is monitored, and whether pairing confirmation information sent by target Bluetooth equipment is received or not is judged based on the monitored information.

If the information received by the mobile phone a is confirmation information allowing pairing, and the confirmation information includes the target UUID, that is, the UUID1, it is determined that the pairing confirmation information sent by the bluetooth headset B is received, and it is determined that the pairing with the target bluetooth device is successful.

In the second case, the local Bluetooth device is a slave device

Referring to fig. 7-2, which is a flowchart illustrating another pairing method for bluetooth devices according to an exemplary embodiment, when the local bluetooth device plays a role in bluetooth communication as a slave device, the step 33 may include the following steps:

in step 33-1, receiving pairing request information sent by an opposite-end Bluetooth device through the ultrasonic communication device, wherein the pairing request information comprises a UUID to be verified;

corresponding to the step 331, when the local-end bluetooth device is a slave-end device, the pairing request information sent by any peer-end bluetooth device may be received, where the pairing request information includes a UUID to be verified.

In step 33-2, traversing the UUID list according to the UUID to be verified;

assuming that the UUID to be checked is specifically UUID1, the local bluetooth device will traverse the generated UUID list according to UUID1, and determine whether the UUID list generated by the local bluetooth device includes UUID 1; if the UUID list includes the UUID1, it is indicated that the local bluetooth device can be paired with the peer bluetooth device, and step 33-3 is executed. If the UUID list does not include the UUID1, it is indicated that the local terminal bluetooth device cannot be paired with the opposite terminal bluetooth device, and the process is ended.

The above describes the step 33-2 by taking the example that the local bluetooth device receives a bluetooth pairing request message.

In an actual application scenario, the local-end bluetooth device may receive pairing request information sent by two or more opposite-end bluetooth devices simultaneously or within a preset time period, where the pairing request information includes device information or device class information in addition to request content and UUID to be verified.

For the application scenario, referring to fig. 8, which is a flowchart illustrating a pairing method for a bluetooth device according to an exemplary embodiment, step 33-2 may include:

in step 33-21, when pairing request information sent by two or more opposite-end bluetooth devices is received, querying a preset device priority list according to device information in the pairing request information, and determining a processing priority of each pairing request information;

in the present disclosure, the device information may be information such as a device name and a device type. The preset device priority list includes a corresponding relationship between device information and device priority, and may be factory default set or set manually by a user. According to the preset device priority list, the processing priority of each pairing request message can be determined.

For example, when pairing request information sent by a plurality of bluetooth devices is received, if the device priority of the bluetooth headset is the highest, the processing priority of the pairing request information sent by the bluetooth headset is also the highest.

In step 33-22, traversing the UUID list according to the UUIDs to be checked in the order of the processing priority from high to low.

In step 33-3, if the UUID list includes the UUID to be verified, sending a confirmation message to the peer bluetooth device through the ultrasonic communication apparatus.

In step 34, after the pairing is successful, the bluetooth control chip is triggered to be turned on, so as to implement bluetooth data transmission with the peer bluetooth device.

In the embodiment of the disclosure, after the local terminal bluetooth device and the opposite terminal bluetooth device are successfully paired through ultrasonic communication, a bluetooth control chip in a bluetooth communication module in the device can be triggered to start, and a bluetooth communication program is started.

While, for purposes of simplicity of explanation, the foregoing method embodiments have been described as a series of acts or combination of acts, it will be appreciated by those skilled in the art that the present disclosure is not limited by the order of acts, as some steps may, in accordance with the present disclosure, occur in other orders and concurrently.
