Exemplary method
As shown in fig. 1, an embodiment of the present invention provides a bluetooth audio data transmission method, where the bluetooth audio data transmission method may be applied to an intelligent terminal, and the intelligent terminal may be an intelligent bluetooth device. In an embodiment of the present invention, the method includes the steps of:
and S100, acquiring the connection quantity of the Bluetooth devices, and establishing Bluetooth connection channels corresponding to the Bluetooth devices one to one according to the connection quantity.
In this embodiment, connection and data transmission of multiple bluetooth devices are implemented, and therefore, in this embodiment, the number of connections of the bluetooth devices needs to be obtained first, and then a corresponding bluetooth connection channel is established according to the number of connections. In this embodiment, the bluetooth device is connected to the intelligent terminal through a preset interface, so that the number of connections of the bluetooth device can be obtained by obtaining parameters of the interface.
Specifically, as shown in fig. 2, the step S100 in the present embodiment includes:
s101, acquiring parameters of a preset interface for connecting with the Bluetooth equipment;
step S102, determining the connection number of the Bluetooth equipment according to the parameters;
and S103, establishing the Bluetooth connection channels according to the connection quantity, wherein the quantity of the Bluetooth connection channels is the same as the connection quantity, and the Bluetooth devices correspond to the Bluetooth connection channels one to one.
In specific implementation, in this embodiment, the connection number of the bluetooth device is determined from the parameters according to the preset interface parameters for connecting with the bluetooth device. Specifically, as shown in fig. 3, after the bluetooth service of the bluetooth device of this embodiment is normally started, it is determined whether the current media _ a2dp _ task is started, if the media _ a2dp _ task is started, it is determined that there is a connected bluetooth device, and if the media _ a2dp _ task is not started, it is determined that there is no connected bluetooth device. Further, when it is determined that there is no connected bluetooth device, that is, the number of connections is 0, the first bluetooth connection channel is established. In one embodiment, the present embodiment sets a first code for the first bluetooth connection channel so as to distinguish between the bluetooth connection channels. For example, as shown in fig. 4, when the media _ A2DP _ task is not started successfully, an AVDTP (AUDIO/VIDEO DISTRIBUTION TRANSPORT PROTOCOL) connection is established, where the AVDTP is a PROTOCOL used to describe transmission of AUDIO/VIDEO between bluetooth devices and is a basic PROTOCOL of an A2DP PROTOCOL, and identifies that the AVDTP stream number ID is 0, that is, the first encoding set for the first bluetooth connection channel is completed. If the connected Bluetooth devices exist, namely the connection quantity is not 0, judging whether the connection quantity exceeds a preset value, and if the connection quantity does not exceed the preset value, establishing the corresponding Bluetooth connection channels according to the connection quantity. In an embodiment, if the preset value is 2, when the connection number is not 0 and is not more than 2, that is, there is only one bluetooth device, the second bluetooth connection channel is established, and each bluetooth device corresponds to one bluetooth connection channel. If the first Bluetooth device corresponds to the first Bluetooth connection channel, the second Bluetooth device corresponds to the second Bluetooth connection channel.
Further, the present embodiment sets a second code for the second bluetooth connection channel. The preset value is 2, that is, after it is determined that the bluetooth devices are connected, it is determined whether the number of the connected bluetooth devices exceeds 2, if not, that is, one bluetooth device is connected, another AVDTP connection is established, and the AVDTP stream number ID of the path is identified to be 1, that is, the second encoding set for the second bluetooth connection channel is completed.
Further, after the Bluetooth connection channel is established, the Bluetooth device sends a control instruction for acquiring audio data to a preset terminal; and then receiving audio data sent by the preset terminal according to the control instruction. Specifically, in the embodiment, the bluetooth device switches the Media Server Audio hall to the A2dp hall mode through the Audio flipper (Audio oscillator), then the A2dp Hal opens a bluetooth Audio output stream, establishes a communication pipeline A2dp _ Ctrl Socket for a control instruction with the bluetooth service process, then sends an instruction Open to each bluetooth connection channel through the A2dp _ Ctrl Socket, and after receiving a response successfully, the intelligent terminal (e.g., the smart television) sends the Start instruction again and starts to transmit Audio data. After receiving the response of the Start instruction response, the intelligent terminal (such as an intelligent television) establishes a Data transmission pipeline A2dp _ Data Socket communicated with the Bluetooth service by an A2dp Hal, and then writes audio Data into a media _ A2dp _ task thread through the A2dp _ Data Socket, namely starts to transmit the audio Data.
Further, in step S200, when the number of the connections is multiple, one path of audio data is obtained, and multiple paths of copy data are copied corresponding to the number of the connections.
In one embodiment, when the number of connections is multiple, it indicates that there are multiple connected bluetooth devices. When data transmission is performed, the embodiment first obtains one path of audio data, and copies multiple paths of copy data corresponding to the connection number. Further, in this embodiment, the audio data and the multiple paths of copy data are further encoded, and the encoded audio data and the multiple paths of copy data are stored in a preset buffer, and the audio data is stored in the buffer, so that the audio data can be more conveniently obtained when the audio data needs to be sent. Specifically, in this embodiment, after the transmitted audio data is received through the media _ a2dp _ task thread, SBC encoding is performed through the codec SBCCodec, and the encoded data (data, that is, audio data) is placed in the buffer area. And the duplicate data is obtained by directly copying the audio data, so that the duplicate data is identical to the audio data.
Further, in step S300, the audio data and the multiple paths of copy data are sent to bluetooth devices through bluetooth connection channels, so that each bluetooth device receives one path of audio data or one path of copy data respectively.
In this embodiment, the present implementation sends the audio data to one of the bluetooth connection channels, and sends the multiple paths of copy data to the remaining bluetooth connection channels, respectively; and when the next data is transmitted, controlling the audio data and the copy data to exchange a Bluetooth connection channel, and controlling the audio data and the copy data to repeatedly exchange the Bluetooth connection channel in subsequent data transmission so as to realize repeated and alternate data transmission.
Specifically, when only a first bluetooth connection channel exists, the audio data is sent to the first bluetooth connection channel, so that the bluetooth device corresponding to the first bluetooth connection channel outputs the audio data. In specific application, as shown in fig. 4, the AVDTP stream number ID may be directly obtained, and if the AVDTP stream number ID is smaller than 1, it indicates that only the first bluetooth connection channel exists, so that the audio data (data) is directly sent to the first bluetooth connection channel.
When the number of connections is multiple, because the number of connections of the bluetooth device is multiple, that is, more than one, when sending the audio data, the obtained audio data is only sent to one of the bluetooth connection channels, and for the remaining bluetooth connection channels, the embodiment sends the copy data to the remaining bluetooth connection channels. Then, when data is transmitted next time, the audio data and the copy data are controlled to be interchanged with a Bluetooth connection channel, and in subsequent data transmission, the audio data and the copy data are controlled to be interchanged with the Bluetooth connection channel repeatedly, so that repeated alternate data transmission is realized. The present embodiment realizes data alternate transmission by interchanging bluetooth connection channels for audio data and copy data. In addition, in this embodiment, only one path of bluetooth device needs to acquire the audio data, and the remaining bluetooth devices only need to copy the audio data and do not need to repeatedly acquire the audio data, thereby avoiding data delay and improving the sending efficiency of the audio data.
Further, in this embodiment, when data transmission is performed, the audio data may also be sent to the bluetooth devices corresponding to one of the bluetooth connection channels, and then the multiple paths of duplicate data are sent to the bluetooth devices corresponding to the remaining bluetooth connection channels respectively; when the next data transmission is carried out, the audio data is sent to the Bluetooth device corresponding to any one of the Bluetooth connection channels of the copy data in the last data transmission process, and the copy data is sent to the Bluetooth devices corresponding to the rest Bluetooth connection channels; and then, when the next data transmission is carried out repeatedly, the audio data is sent to the Bluetooth device corresponding to any one of the Bluetooth connection channels of the copy data in the last data transmission process, and the copy data is sent to the Bluetooth devices corresponding to the rest Bluetooth connection channels, so that the repeated alternate fine data transmission is realized. That is to say, the invention repeatedly and alternately sends the video data and the copy data, reduces the time difference of the data received by a plurality of Bluetooth devices, and leads each Bluetooth device to synchronously receive the data.
For example, when there are 2 bluetooth devices, there are bluetooth devices corresponding to the first bluetooth connection channel and bluetooth devices corresponding to the second bluetooth connection channel. When data transmission is carried out, firstly, audio data (data) are transmitted to the Bluetooth device connected with the first Bluetooth connection channel, and meanwhile, copy data (data 1) are transmitted to the second Bluetooth connection channel. In this embodiment, the copy data is obtained by copying the audio data from the preset buffer area. That is, the audio data and the copy data are the same data. Then, when data is transmitted next time, the embodiment first sends the audio data (data) to the bluetooth device connected with the second bluetooth connection channel, and then sends the copy data (data 1) to the bluetooth device connected with the first bluetooth connection channel; in the next data transmission, the audio data (data) is firstly transmitted to the bluetooth device connected with the first bluetooth connection channel, then the copy data (data 1) is transmitted to the bluetooth device connected with the second bluetooth connection channel, and the steps are repeated to realize repeated alternate transmission of the data, so that each bluetooth device can receive the data firstly in turn, the problem that the time difference is gradually accumulated and increased due to the fact that the same bluetooth device receives the data firstly all the time is avoided, the data received by the two bluetooth devices are synchronous as a whole, the problem of two-path audio asynchronization can be reduced, the quality of audio transmission is improved, and the multi-path bluetooth device connection is realized.
In summary, in the embodiments of the present invention, the bluetooth connection channels may be established according to the connection number of the bluetooth devices, and then the audio data is output to the corresponding bluetooth connection channels, when the audio data is output, the audio data is first obtained, and the multiple paths of copy data are copied according to the connection number, and then the audio data and the multiple paths of copy data are sent to the bluetooth devices through the bluetooth connection channels.
