Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, exemplary embodiments according to the present application will be described in detail below with reference to the accompanying drawings. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the application described in the application without inventive step, shall fall within the scope of protection of the application.
Fig. 1 shows a schematic block diagram of a bluetooth device 100 according to an embodiment of the present application. As shown in fig. 1, bluetooth device 100 includes a memory 110, a processor 120, and a communication interface 130. Wherein the memory 110 has stored therein audio information for broadcasting the pairing and a computer program executed by the processor 120, which, when executed by the processor 120, performs the following operations: acquiring audio information from the memory 110 when the bluetooth device 100 enters the pairing mode, the audio information being associated with device information of the bluetooth device 100; the audio information is distributed through the broadcast channel via the communication interface 130 so that another device receives the audio information by listening to the broadcast and completes a pairing connection with the bluetooth device 100 based on the audio information.
In the embodiment of the present application, the memory 110 of the bluetooth device 100 stores therein audio information for broadcasting pairing, the audio information being associated with device information of the bluetooth device 100; when the bluetooth device 100 enters the pairing connection mode (such as when the bluetooth device 100 is paired with another device for the first time or when the bluetooth device 100 changes a pairing object), the processor 120 of the bluetooth device 100 may obtain the AUDIO information from the memory 110 and issue the AUDIO information through a broadcast channel (such as a low-power and high-performance LE-AUDIO broadcast channel) via the communication interface 130, so that another device waiting to be paired with the bluetooth device 100 can receive the AUDIO information by monitoring a broadcast, and obtain the device information of the bluetooth device 100 based on the AUDIO information, thereby completing pairing connection with the bluetooth device 100 automatically, and without manual operation of discovering devices and connected devices by a user, implementing non-inductive pairing connection, and improving user experience.
In the embodiment of the present application, the audio information may be generated by the processor 120 based on the device information of the bluetooth device 100 acquired from the memory 110 after the bluetooth device 100 is powered on; the device information includes, among other things, a Media Access Control (MAC) address, a device serial number (ID), and a device name of the bluetooth device 100. In this embodiment, the audio information for broadcast pairing includes the MAC address, device ID, and device name of the bluetooth device 100, and since both the MAC address and device ID of the bluetooth device 100 cannot be changed and the device name is user-modifiable, the audio information can be updated according to the device name modified by the user after the user modifies the name of the bluetooth device 100. However, for a bluetooth device 100 such as a bluetooth headset, it is generally inconvenient for a user to modify the device name before the first pairing connection, but generally modify the device name through a display interface of another device (such as a mobile phone end) after completing the pairing connection, so that the audio information for broadcast pairing is not required to be updated for the first pairing connection scenario, and the audio information for broadcast pairing may be required to be updated for the re-pairing connection scenario.
In a further embodiment of the present application, the device information of the bluetooth device 100 may further include a connection priority level, and the connection priority level defaults to a lowest priority level, and the processor 120 may further be configured to: updating audio information based on the modified device information in response to receiving a user's modification instruction for the connection priority when the bluetooth device 100 enters the pairing mode; the updated audio information is distributed through the broadcast channel via the communication interface 130 so that another device selects the bluetooth device 100 having the highest connection priority level to pair with the connection when receiving a plurality of audio information for broadcast pairing.
In this embodiment, a solution is provided for a scenario where multiple bluetooth devices are simultaneously broadcasting pending pairings. Specifically, the user may modify the connection priority of the bluetooth device 100 that the user desires to pair and connect, so that the bluetooth device 100 updates and distributes the audio information used for broadcast pairing, and thus, when another device receives multiple audio information for broadcast pairing, the device information included in each audio information may be analyzed, and the connection priority in the device information is traversed, and the bluetooth device with the highest connection priority is selected from the device information to complete pairing and connection.
It should be noted that the modification of the connection priority by the user may only work on the pairing connection, in other words, after the pairing connection is completed, the connection priority may be restored to the initial default level, because the bluetooth device 100 is not necessarily the bluetooth device 100 that the user desires to be paired when the pairing connection is performed next time, and therefore it is sufficient to keep the connection priority of the bluetooth device 100 modified and updated in real time according to the user requirement.
In one embodiment of the present application, the aforementioned bluetooth device 100 may be a wireless bluetooth headset, and the user may modify the connection priority of the bluetooth headset by performing a triggering action on a charging box of the wireless bluetooth headset, for example. For example, the connection priority level of the bluetooth headset is modified by performing an opening and closing action on the charging box. In one example, the connection priority level of the bluetooth device 100 initially defaults to 0, and the user performs a switch cover action on the charging box, and the switch cover action is increased by one level every time the charging box is switched, for example, 5 times the charging box is switched may correspond to the earphone connection priority level being modified to 5.
In another embodiment of the present application, the aforementioned bluetooth device 100 may be a bluetooth headset, and the user may modify the connection priority level of the bluetooth headset by performing a triggering action on a certain key (e.g., a pairing key) on the bluetooth headset. For example, the connection priority level of the bluetooth headset is modified by performing a pressing action on a key. In one example, the connection priority level of the bluetooth device 100 initially defaults to 0, and the user presses a key, which increases by one level each time the user presses the key.
In an embodiment of the present application, the processor 120 generates audio information for broadcast pairing based on the device information of the bluetooth device 100, which may include: combining the equipment information with the specific protocol header and the protocol frame into information to be processed; encrypting information to be processed to obtain encrypted text information (such as through hash operation); converting the encrypted text information into encrypted audio information (such as by a TTL text-to-speech algorithm, etc.); the encrypted audio information is compressed to obtain audio information for the broadcast pairing (such as by the OPUS algorithm). Wherein the specific protocol headers and protocol frames are associated with the broadcast technology supported by the processor 120. In this embodiment, the device information of the bluetooth device 100 is encrypted to obtain text information, and the text information is converted into audio information and then compressed to obtain audio information for broadcast pairing, so that not only can the security of broadcast data be ensured, but also the data transmission efficiency can be improved.
The above exemplarily illustrates the bluetooth device 100 according to the embodiment of the present application. Based on the above description, the bluetooth device 100 according to the embodiment of the present application issues the audio information associated with the device information through the broadcast channel when performing pairing connection, so that another device waiting for pairing with the bluetooth device can receive the audio information by monitoring the broadcast, and obtain the device information of the bluetooth device based on the audio information, thereby automatically completing pairing connection with the bluetooth device, without a manual operation of a user for discovering the device and the connection device, realizing non-inductive pairing connection, and improving user experience.
A terminal device 200 provided according to another aspect of the present application, which can cooperate with the bluetooth device 100 described above to realize auto-pairing connection between them, is described below with reference to fig. 2. As shown in fig. 2, terminal device 200 may include memory 210, processor 220, and communication interface 230. Wherein the memory 210 stores therein a computer program to be executed by the processor 220, the computer program, when executed by the processor 220, performs the following operations: listen for broadcasts over a broadcast channel via the communication interface 230; when audio information for broadcast pairing is received from a broadcast channel, acquiring equipment information of Bluetooth equipment issuing the audio information based on the audio information, and completing pairing connection with the Bluetooth equipment based on the equipment information.
In the embodiment of the present application, the processor 220 of the terminal device 200 may receive AUDIO information for broadcast pairing of the bluetooth device by monitoring broadcast of a specific broadcast channel (i.e., a broadcast channel for broadcasting AUDIO information by the bluetooth device described above, such as an LE-AUDIO broadcast channel) via the communication interface 230, and after receiving the AUDIO information, the processor 220 may parse the AUDIO information to obtain device information of the bluetooth device (how to parse may depend on a generation process of the AUDIO information, which may include decompression and decryption in the example described above), so as to automatically pair and connect with the bluetooth device, and do not need a manual operation of a user to discover the device and the connected device, thereby implementing an imperceptible pairing connection and improving user experience.
In an embodiment of the present application, the device information of the bluetooth device may include a media access control address, a device serial number, and a device name, as described above. Accordingly, the processor 220 may initiate a connection to the bluetooth device based on the mac address and the device serial number, and display the device name of the bluetooth device by a display (not shown) of the terminal device 200 after completing a pairing connection with the bluetooth device, so as to display a pairing success result. Which in this embodiment may be a scenario where the processor 220 receives an audio message.
In another scenario, the processor 220 may receive a plurality of audio information for broadcast pairing. In this scenario, in an embodiment, as described above, the device information of the bluetooth device may further include a connection priority level, and the processor 220 may be further configured to: when a plurality of audio information for broadcast pairing is received from a broadcast channel, the connection priority level of each corresponding Bluetooth device is obtained based on each audio information, and the Bluetooth device with the highest connection priority level is selected for pairing connection. In this embodiment, the processor 220 may store the device information of the multiple bluetooth devices in a linked list, and cyclically traverse the connection priority levels in the device information, and select a bluetooth device with the highest connection priority level to complete pairing connection, which may greatly improve user experience for a scenario in which a plurality of bluetooth devices of the same type or with the same display name are to be paired and connected in the same place and in the same time period, compared with an existing method of manual operation by a user.
In another embodiment, the processor 220 may be further configured to: when a plurality of audio information for broadcast pairing are received from a broadcast channel, the Bluetooth device pairing connection corresponding to the audio information with the highest signal strength is selected based on the signal strength of each audio information. In this embodiment, the audio information for broadcast pairing issued by the bluetooth device may not necessarily include the connection priority level, and when the processor 220 of the terminal device 200 receives a plurality of audio information for broadcast pairing from a broadcast channel, the processor 220 may select a bluetooth device pairing connection corresponding to the audio information with the highest signal strength based on the signal strength of each audio information. For example, in general, the closer a bluetooth device is to the terminal device 200, the greater the signal strength of the audio information that the terminal device 200 receives its broadcast, and the more likely it is that the bluetooth device that the user desires to be paired to connect. Thus, this embodiment provides another solution for multiple bluetooth device selection to enable auto-pairing connections, which is also applicable to the case where the connection priority levels are included in the audio information, but the connection priority levels of the multiple bluetooth devices are the same (i.e., the user may not perform a triggering action to modify the connection priority levels).
In further embodiments of the present application, the processor 220 may be further configured to: starting a timer when a plurality of audio information for broadcast pairing is received from a broadcast channel; when new audio information for broadcast pairing is received again within the preset time of the timer, restarting the timer until the new audio information for broadcast pairing is no longer received within the preset time; and when new audio information for broadcast pairing is not received within the preset time, selecting Bluetooth equipment with the highest connection priority level from the Bluetooth equipment corresponding to the received audio information for pairing connection, or selecting Bluetooth equipment corresponding to the audio information with the highest signal intensity for pairing connection. In this embodiment, the terminal device 200 further ensures that bluetooth devices that may need pairing connection are not missed by setting a timer to determine whether new audio information will be received. For example, when the terminal device 200 receives a plurality of audio information for broadcast pairing at the same time, the time may be counted for 3 seconds, and if new audio information is received within 3 seconds, the time is counted for 3 seconds again, and after 3 seconds, a connection is initiated to the device with the highest connection level or the highest signal strength.
In an embodiment of the present application, the above-described operations performed by the processor 220 of the terminal device 200 may be implemented by an application program (APP). When the bluetooth device enters the pairing mode, the terminal device 200 may enter the broadcast monitoring mode through the APP to realize the automatic pairing connection with the bluetooth device. Finally, the device name of the paired bluetooth device can be displayed on the APP; when the audio information of a plurality of Bluetooth devices is monitored, the audio information can be displayed, and the device with the highest connection grade or the device with the highest signal strength is selected to initiate connection. Generally, the APP on the terminal device 200 needs to be turned on only at the first connection. Subsequently, when the bluetooth device connects to the terminal device 200 again, the aforementioned operation is not needed, that is, the APP does not need to be started.
Based on the above description, the terminal device 200 according to the embodiment of the present application receives audio information of a bluetooth device for broadcast pairing by monitoring a specific broadcast channel, and obtains device information of the bluetooth device based on the received audio information, so as to pair and connect with the bluetooth device automatically, without manual operations of a user for discovering the device and the connected device, thereby implementing non-inductive pairing connection, and improving user experience.
