At least two bluetooth chips are provided in each of the first bluetooth device 210 and the second bluetooth device 220. In fig. 2, a first bluetooth device 210 is taken as a smart phone provided with two bluetooth chips, and a second bluetooth device 220 is taken as an example of a smart speaker provided with two bluetooth chips.

When receiving the selected operation of the second Bluetooth device, the first Bluetooth device establishes at least two Bluetooth connections with the second Bluetooth device through at least two Bluetooth chips.
In an illustrative example, 2 bluetooth chips are provided in a first bluetooth device and 2 bluetooth chips are provided in a second bluetooth device, and the first bluetooth device can establish 2 bluetooth connections with the second bluetooth device.
In another illustrative example, 3 bluetooth chips are provided in a first bluetooth device and 2 bluetooth chips are provided in a second bluetooth device, the first bluetooth device being capable of establishing 2 bluetooth connections with the second bluetooth device.
In step 402, the second bluetooth device establishes m bluetooth connections with the first bluetooth device through m bluetooth chips of the at least two bluetooth chips.
Correspondingly, the second Bluetooth device establishes m Bluetooth connections with the first Bluetooth device.
In step 403, the first bluetooth device receives an audio playing instruction, where the audio playing instruction is used to instruct playing of audio in the first bluetooth device by the second bluetooth device.
In this embodiment, the second bluetooth device is a bluetooth device with an audio playing function, for example, the second bluetooth device is a bluetooth speaker or a bluetooth headset, and after the bluetooth connection is established with the second bluetooth device, the first bluetooth device can play audio through the second bluetooth device.
Optionally, the audio playing instruction is manually triggered by the user, for example, when a playing operation of the audio and video file in the first bluetooth device is received, it is determined that the audio playing instruction is received; alternatively, the audio playing instruction may be triggered automatically after the bluetooth connection is established, for example, after the bluetooth device is established with the second bluetooth device, the first bluetooth device plays all the audio of the local terminal, such as game audio, key sound, alert sound, etc., which is not limited in this embodiment.
In step 404, the first bluetooth device sends audio data to the second bluetooth device through m bluetooth connections according to the audio playing instruction, wherein different bluetooth connections are used for sending audio data of the same audio.
Further, the first bluetooth device transmits audio data (audio data stream) to the second bluetooth device through m bluetooth connections. Compared with the prior art that audio data transmission is carried out through a single Bluetooth connection, audio data transmission is carried out through m Bluetooth connections, and the transmission rate can reach m times of the original transmission rate, so that the transmission rate is improved under the condition of guaranteeing transmission delay, and transmission and playing of higher-quality audio are realized.
Optionally, before the first bluetooth device sends the audio data, the audio data is divided into m paths of audio data by the audio processing chip, so that the m paths of audio data are transmitted.
In one possible implementation, different bluetooth connections are used to transmit different audio data of the same audio, e.g., different bluetooth connections are used to transmit audio data of different channels, or different bluetooth connections are used to transmit the same audio data of the same audio, e.g., different bluetooth connections are used to transmit audio data of both the left and right channels.
In step 405, the second bluetooth device receives audio data sent by the first bluetooth device through m bluetooth connections.
Correspondingly, the second Bluetooth device receives the audio data through m Bluetooth connections. Optionally, the second bluetooth device sends the received audio data to the audio processing chip, so that the audio processing chip parses and plays the received audio data.
In step 406, the second bluetooth device performs audio playback according to the audio data.
In this embodiment of the present application, the second bluetooth device has an audio playing component, such as a speaker, and after parsing the audio data, the second bluetooth device performs audio playing through the audio playing component.
In summary, in the embodiment of the present application, at least two bluetooth chips are set in a bluetooth device, and at least two bluetooth connections are established between bluetooth devices through the at least two bluetooth chips, so that when audio transmission is performed, audio data transmission is performed through the at least two bluetooth connections; compared with the related art, the transmission bandwidth between the Bluetooth devices is improved, so that high-quality audio playing can be realized, and the playing tone quality of the Bluetooth audio is improved.
In one possible implementation, the bluetooth chip in the first bluetooth device (or the second bluetooth device) includes a master bluetooth chip and a slave bluetooth chip, and in the bluetooth connection establishment phase, the first bluetooth device first establishes a master bluetooth connection with the second bluetooth device through the master bluetooth chip, and further establishes a slave bluetooth connection with the second bluetooth device based on the established master bluetooth connection, which is described below using an exemplary embodiment.
Referring to fig. 5, a flowchart of an audio transmission method between bluetooth devices according to another exemplary embodiment of the present application is shown. This embodiment is illustrated by the application of the method to the implementation environment shown in fig. 2. The method comprises the following steps:
in step 501, the first bluetooth device establishes a master bluetooth connection with a second master bluetooth chip in the second bluetooth device through a first master bluetooth chip in the n bluetooth chips.
In one possible embodiment, for a bluetooth device provided with at least two bluetooth chips, when the bluetooth function is turned on, the bluetooth device starts a master bluetooth chip among the bluetooth chips and searches for other bluetooth devices of the accessory through the master bluetooth chip. Wherein, at least two bluetooth chips include a master bluetooth chip, and remaining n-1 bluetooth chips are all from bluetooth chip.
In one possible implementation, when the first bluetooth device starts the bluetooth function, i.e. bluetooth scanning is performed by the first main bluetooth chip, and when the second bluetooth device starts the bluetooth function, i.e. bluetooth scanning is performed by the second main bluetooth chip. When the first main Bluetooth chip scans the second Bluetooth device, the first Bluetooth device displays the second Bluetooth device on a Bluetooth scanning interface, and establishes main Bluetooth connection with a second main Bluetooth chip in the second Bluetooth device when receiving the selection operation of the second Bluetooth device. The process of establishing the main bluetooth connection between the main bluetooth chips is similar to the conventional bluetooth connection establishment manner, and this embodiment is not described herein.
Optionally, after the first bluetooth device and the second bluetooth device establish the main bluetooth connection for the first time, the first bluetooth device and the second bluetooth device both record the opposite bluetooth device, and when the opposite bluetooth device is scanned again subsequently, the main bluetooth connection can be directly established.
Step 502, the second bluetooth device establishes a master bluetooth connection with a first master bluetooth chip in the first bluetooth device through a second master bluetooth chip in the m bluetooth chips.
Correspondingly, the second Bluetooth device establishes a master Bluetooth connection with the first Bluetooth device through the second master Bluetooth chip.
In step 503, the first bluetooth device establishes m-1 slave bluetooth connections with the second bluetooth device via the master bluetooth connection.
After the main Bluetooth connection is established, the first Bluetooth device can perform data communication with the second Bluetooth device. For the bluetooth device provided with a plurality of bluetooth chips, if users need to manually establish a plurality of bluetooth connections between bluetooth devices, a lot of time will be consumed and connection establishment errors are easily caused.
In one possible implementation, in order to determine whether the opposite bluetooth device that establishes the master bluetooth connection has at least two bluetooth chips, i.e., whether a slave bluetooth connection can be established with the opposite bluetooth device, the first bluetooth device and the second bluetooth device perform information interaction through the master bluetooth connection, and further establish the slave bluetooth connection when it is determined that the opposite bluetooth device has at least two bluetooth chips.
Alternatively, as shown in fig. 6, the present step may include the following steps.
In step 503A, the first bluetooth device performs bluetooth information interaction with the second bluetooth device through the master bluetooth connection, where the bluetooth information at least includes the number of bluetooth chips in the bluetooth device.
In one possible implementation, after the main bluetooth connection is established, the second bluetooth device sends second bluetooth information to the first bluetooth device through the main bluetooth connection, where the second bluetooth information includes the number of bluetooth chips in the second bluetooth device. Alternatively, the number of bluetooth chips is the number of available bluetooth chips, i.e. bluetooth chips for which bluetooth connections have been established are removed.
Further, if the number of bluetooth chips in the second bluetooth device is greater than or equal to 2, determining that the second bluetooth device supports to establish a plurality of bluetooth connections, thereby executing step 503B; if the number of Bluetooth chips in the second Bluetooth device is smaller than 2, determining that the second Bluetooth device does not support establishing a plurality of Bluetooth connections, and thus establishing a main Bluetooth connection with the second Bluetooth device only.
It should be noted that, for the bluetooth device provided with a single bluetooth chip, the number of bluetooth chips at the home end will not be sent to the opposite end after the bluetooth connection is established, and correspondingly, if the bluetooth information sent by the second bluetooth device is not received, the first bluetooth device determines that the second bluetooth device does not support establishing multiple bluetooth connections.
In step 503B, if the number of bluetooth chips in the second bluetooth device is at least two, the first bluetooth device starts the first slave bluetooth chip in the first bluetooth device.
Optionally, in view of power consumption, after the bluetooth device provided with at least two bluetooth chips starts the bluetooth function, only the master bluetooth chip is started, so that when it is determined that a plurality of bluetooth connections can be established with the second bluetooth device, the first bluetooth device needs to start the first slave bluetooth chip, so that a slave bluetooth connection is established subsequently. Wherein the number of the first slave Bluetooth chips is at least one.
After the first slave Bluetooth chip is started, bluetooth broadcasting can be performed so as to be discovered by other Bluetooth devices.
In step 503C, the first bluetooth device establishes a slave bluetooth connection with a second slave bluetooth chip in the second bluetooth device through the first slave bluetooth chip.
In one possible implementation manner, after the first bluetooth device determines that the second bluetooth device includes at least two bluetooth chips, bluetooth information of each slave bluetooth chip in the second bluetooth device is further obtained through the master bluetooth connection, so that the slave bluetooth chip of the local terminal and each slave bluetooth chip of the opposite terminal are controlled to establish a slave bluetooth connection according to the bluetooth information.
Optionally, the step includes the following steps.
1. And acquiring the Bluetooth MAC address of the second slave Bluetooth chip through the master Bluetooth connection.
In one possible implementation, after the second bluetooth device determines that the first bluetooth device includes a plurality of bluetooth chips, the second bluetooth device sends a bluetooth MAC address of the second slave bluetooth chip to the first bluetooth device through the master bluetooth connection, so that the first bluetooth device establishes a slave bluetooth connection with the second bluetooth device according to the bluetooth MAC address. Correspondingly, the first Bluetooth device acquires the Bluetooth MAC address through the main Bluetooth connection.
In this embodiment of the present application, different bluetooth chips in the bluetooth device have different bluetooth MAC addresses, and the bluetooth MAC addresses have uniqueness, so that different bluetooth chips can be distinguished according to the bluetooth MAC addresses, thereby establishing a slave bluetooth connection.
2. And establishing a slave Bluetooth connection with the second slave Bluetooth chip through the first slave Bluetooth chip according to the Bluetooth MAC address.
Further, the first Bluetooth device establishes a slave Bluetooth connection with a second slave Bluetooth device indicated by the Bluetooth MAC address through the first slave Bluetooth chip.
In one possible implementation, the first bluetooth device matches the acquired bluetooth MAC address with each scanned bluetooth device, thereby establishing a bluetooth connection with the matched bluetooth device (i.e., the second slave bluetooth chip).
Optionally, when a slave bluetooth connection needs to be established between at least two first slave bluetooth chips and at least two second slave bluetooth chips, the first bluetooth device matches the first slave bluetooth chips with the second slave bluetooth chips one by one, so that a slave bluetooth connection is established between the matched first slave bluetooth chips and the second slave bluetooth chips, and multiple bluetooth connections are avoided being established by the same slave bluetooth chip.
In step 504, the second bluetooth device establishes m-1 slave bluetooth connections with the first bluetooth device via the master bluetooth connection.
Corresponding to step 503 above, the second bluetooth device establishes a slave bluetooth connection with the first bluetooth device when it recognizes that it is provided with at least two bluetooth chips. In one possible embodiment, as shown in fig. 7, this step includes the following steps.
In one possible implementation, after the main bluetooth connection is established, the first bluetooth device sends first bluetooth information to the second bluetooth device through the main bluetooth connection, where the first bluetooth information includes the number of bluetooth chips in the first bluetooth device. Alternatively, the number of bluetooth chips is the number of available bluetooth chips, i.e. bluetooth chips for which bluetooth connections have been established are removed.
Further, if the number of bluetooth chips in the first bluetooth device is greater than or equal to 2, determining that the first bluetooth device supports to establish a plurality of bluetooth connections, thereby executing step 504B; if the number of Bluetooth chips in the first Bluetooth device is smaller than 2, it is determined that the first Bluetooth device does not support establishment of a plurality of Bluetooth connections, and therefore only a main Bluetooth connection is established with the first Bluetooth device.
It should be noted that, for the bluetooth device provided with a single bluetooth chip, the number of bluetooth chips at the home end will not be sent to the opposite end after the bluetooth connection is established, and correspondingly, if the bluetooth information sent by the first bluetooth device is not received, the second bluetooth device determines that the first bluetooth device does not support to establish multiple bluetooth connections.
In step 504B, if the number of bluetooth chips in the first bluetooth device is at least two, a second slave bluetooth chip in the second bluetooth device is started.
Optionally, upon determining that multiple bluetooth connections can be established with the first bluetooth device, the second bluetooth device needs to activate a second slave bluetooth chip in order to subsequently establish slave bluetooth connections. Wherein the number of the second slave Bluetooth chips is at least one.
After the second slave Bluetooth chip is started, bluetooth broadcasting can be performed so as to be discovered by other Bluetooth devices.
In step 504C, a slave bluetooth connection is established with a first slave bluetooth chip in the first bluetooth device via the second slave bluetooth chip.
In one possible implementation, after the second bluetooth device determines that the first bluetooth device includes at least two bluetooth chips, the first bluetooth device further transmits bluetooth information of the second slave bluetooth chip through the master bluetooth connection, so that the first bluetooth device controls the first slave bluetooth chip to establish a slave bluetooth connection with the second slave bluetooth chip according to the bluetooth information.
Optionally, the second bluetooth device sends the bluetooth MAC address of the second slave bluetooth chip to the first bluetooth device via the master bluetooth connection.
It should be noted that, the second bluetooth device may also obtain, through the master bluetooth connection, the bluetooth MAC address of the first slave bluetooth chip in the first bluetooth device, so that when the slave bluetooth connection is established, authentication is performed according to the bluetooth MAC address, which is not described herein in detail.
In step 505, the first bluetooth device receives an audio playing instruction, where the audio playing instruction is used to instruct playing of audio in the first bluetooth device by the second bluetooth device.
The implementation of this step may refer to step 403, and this embodiment is not described herein.
In step 506, the first bluetooth device determines an audio code rate of the target audio indicated by the audio play instruction.
When the tone quality of the target audio to be played is poor (for example, the audio rate is lower than 1M/s), the audio rate of the target audio can be achieved through the single Bluetooth connection, and at the moment, the audio data transmission is not needed through a plurality of Bluetooth connections. Therefore, in one possible implementation, before the first bluetooth device sends bluetooth data, the audio code rate of the target audio is performed, if the audio code rate is higher than the code rate threshold, step 507 is performed, and if the audio code rate is lower than the code rate threshold, the audio data is transmitted only through the master bluetooth connection.
The code rate threshold may be a transmission bandwidth of a single bluetooth connection, for example, the code rate threshold is 1M/S.
In step 507, if the audio code rate is higher than the code rate threshold, the first bluetooth device sends audio data to the second bluetooth device through m bluetooth connections.
When the audio code rate is higher than the code rate threshold, the first Bluetooth device sends the audio data to the second Bluetooth device through m Bluetooth connections, so that the transmission rate and the bandwidth of the audio data are improved.
In one possible implementation, when the target audio is multi-channel audio, the first bluetooth device processes the audio data based on the channels before transmitting the audio data, thereby transmitting the processed audio output to the second bluetooth device over the m bluetooth connections. Optionally, the step includes the following steps.
1. And generating m paths of audio data according to the target audio, wherein each path of audio data corresponds to each audio channel.
Optionally, the first bluetooth device divides the target audio into m paths of audio data according to the audio channel through the audio processing component. For example, when the target audio is two-channel audio, the first bluetooth device divides the target audio into left-channel audio data and right-channel audio data. Of course, when the target audio is 2.1 channels, 3.1 channels or 5.1 channels, the first bluetooth device may divide the target audio into m channels of audio data, which is not limited in this embodiment.
2. And sending m paths of audio data to the second Bluetooth device through m Bluetooth connections, wherein the m paths of audio data are subjected to time synchronization.
In the embodiment of the application, in order to ensure that the multiple paths of audio data are synchronous when the second bluetooth device plays audio, when the first bluetooth device sends m paths of audio data, time synchronization needs to be performed on the m paths of audio data, namely, the multiple paths of audio data at the same moment in the target audio are simultaneously sent.
In one possible implementation, the first bluetooth device may set an audio time stamp for each path of audio data, thereby achieving audio synchronization.
In step 508, the second bluetooth device receives the audio data sent by the first bluetooth device through m bluetooth connections.
Correspondingly, the second Bluetooth device receives m paths of audio data sent by the first Bluetooth device through m Bluetooth connections.
