[0051] The exemplary embodiments will be described in detail below with reference to the drawings. The following description is only examples of the exemplary embodiments and does not represent all of the embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0052] At present, the low-power Bluetooth technology is developing, and the power consumption of the low-power Bluetooth technology is greatly reduced compared with the classic Bluetooth technology. The working principles of the classic Bluetooth device and the low-power Bluetooth device are completely different. The low-power Bluetooth device can directly listen to the broadcast data of the broadcast device, and the classic Bluetooth device complying with the classic Bluetooth communication protocol does not support the broadcast listening technology.

[0053] Based on the Bluetooth technology protocol standard, the broadcast device sends a broadcast data packet to the outside in a broadcast manner, and the device supporting the broadcast listening technology receives the broadcast data packet and plays the to-be-played data (audio data) in the broadcast data packet. However, because the development time of the broadcast listening technology is short, there are few devices supporting the broadcast listening technology on the market at present, and most of them are classic Bluetooth devices that do not support the broadcast listening technology. Users using the classic Bluetooth device cannot listen to the broadcast, and need to replace the device to be able to listen to the broadcast, which increases the device purchase cost of the users.

[0054] To solve the above problems, the present disclosure provides a communication method. By using the method in the present disclosure, the communication device receives the broadcast data packet sent by the broadcast device, and converts the first data in the broadcast data packet that the first Bluetooth device does not support playing into second data that the first Bluetooth device supports playing based on a first encoding manner and a second encoding manner, and sends the second data to the first Bluetooth device. In this way, the user can listen to the broadcast data using the first Bluetooth device without replacing the existing Bluetooth device, which not only saves the user's money, but also improves the user's experience.

[0055] The present disclosure is applicable to a broadcast scene, such as an audio broadcast scene, for example. Figure 1 As shown in the schematic diagram of the application scenario of the present disclosure, the schematic diagram of the application scenario includes at least one first Bluetooth device (a plurality of first Bluetooth devices are shown in the figure), a broadcast device, and a terminal device (i.e., a communication device). To make the present disclosure clearer and easier to understand, the relationship between the first Bluetooth device, the broadcast device, and the terminal device is represented by the data flow direction (the arrow direction shown in the figure represents the data flow direction). Figure 1 Figure 1 Specifically, with reference to

[0056] Specifically, with reference to Figure 1 ​The data flow of the present disclosure is that the broadcast device sends the broadcast data packet outward, the terminal device receives the broadcast data packet, and the terminal device sends the audio data generated based on the broadcast data packet to the first Bluetooth device. The terminal device (that is, the communication device using the method in the present disclosure) can be a mobile phone, a tablet computer, a smart wearable device, etc. used by a user, and the first Bluetooth device can be a Bluetooth device that does not support broadcast listening technology, such as a classic Bluetooth device (that is, a Bluetooth device complying with a classic Bluetooth protocol), used by the user, and the first Bluetooth device is in Bluetooth connection with the terminal device of the user. Among them, the application scenario can include at least one first Bluetooth device, and when the application scenario includes multiple first Bluetooth devices, the terminal device is in Bluetooth communication connection with each first Bluetooth device respectively.

[0057] It should be noted that the first Bluetooth device can be a device such as a Bluetooth headset or a sound box that lacks a user interface, and it is inconvenient for the user to target the first Bluetooth device for operation. By setting a terminal device with a display interface, the user can complete the control of the first Bluetooth device on the user interface of the terminal device. The terminal device receives the broadcast data packet sent by the broadcast device, the terminal device converts the data type in the broadcast data packet into a data type supported by the first Bluetooth device, and the first Bluetooth device receives the audio data converted by the terminal device and plays the audio data. For example, the user can select the first Bluetooth device as the Bluetooth device for listening to the broadcast on the user interface of the terminal device, thereby improving the operation experience of the user and facilitating the user to select the Bluetooth device for listening to the broadcast according to the needs.

[0058] Among them, as Figure 1 shown, the first Bluetooth device can be connected to the terminal device through an EDR (Enhanced data rate) connection. The EDR technology can improve the data transmission speed of the Bluetooth device. In addition, due to the bandwidth advantage of the EDR technology, the terminal device can simultaneously connect multiple first Bluetooth devices.

[0059] The exemplary embodiment of the present disclosure provides a communication method applied to a terminal device. The terminal device has a communication function and can be in communication connection with a Bluetooth device. The terminal device can be a smart device such as a mobile phone, a tablet computer, a notebook computer, a smart robot, and a smart wearable device. In addition, the terminal device is also provided with various hardware resources and an energy storage device for providing power for the operation of the various hardware resources.

[0060] As Figure 2 shown, the communication method shown in the embodiment includes the following steps.

[0061] S201, receiving a broadcast data packet sent by a broadcast device.

[0062] S202. Based on the broadcast data packet, convert the first data into the second data.

[0063] S203, Send the second data to the first Bluetooth device.

[0064] It should be noted that the broadcasting device in this embodiment can be a broadcasting device already existing in related technologies. The first Bluetooth device is a classic Bluetooth device, which cannot parse and play the data format in the broadcast data packets sent by the broadcasting device. Since the first Bluetooth device cannot directly listen to the broadcast data packets sent by the broadcasting device, therefore, referring to... Figure 1 The illustrated application scenario diagram shows that a terminal device can receive broadcast data packets sent by a broadcasting device, process the data in the broadcast data packets, convert it into a data format that a first Bluetooth device can play, and then send the audio data in the format that the first Bluetooth device can play to the first Bluetooth device, which will then play the audio content in the broadcast data packets.

[0065] In step S201, when there are multiple first Bluetooth devices that establish a connection with the terminal device, the first Bluetooth device that performs audio data playing can be selected on an interface in the terminal device. In an example, the first data is included in the broadcast data packet, and the first data is encoded in a first encoding manner supported by the broadcast device. The first encoding manner refers to an encoding manner adopted by the broadcast device when broadcasting the to-be-broadcast data. The first encoding manner can be an LC3 (Low Complexity Communications Codec) encoding manner, an LC3plus encoding manner, or an APTX lossness encoding manner. The encoding process of the LC3 encoding manner can be to convert a sound signal in a time domain to a frequency domain using a low-delay improved discrete cosine transform. In the frequency domain, a spectral noise shaping module processes each frequency component to reduce perceptible spectral quantization noise. A temporal noise shaping module reduces perceptible temporal quantization noise. The signal components processed by the spectral noise shaping module and the temporal noise shaping module are quantized by a spectral quantizer module. Spectral coefficients quantized to 0 will be replaced by noise during decoding to reduce artifacts. The spectral coefficients are subjected to an entropy encoding and multiplexing process to form an audio encoding bitstream. The LC3 encoding manner is a low-delay audio encoding technology that can achieve efficient compression and provide better sound quality while maintaining extremely low delay. In this way, at the same time of the same data transmission rate, the LC3 encoding manner can transmit higher-quality audio. At the same time, the LC3 encoding manner also has better fault tolerance and can maintain good sound quality in poor network environments. In addition, the LC3 encoding manner also supports variable bit rate encoding. This means that the LC3 encoder can automatically adjust the encoding rate during transmission according to the complexity of the audio signal, thereby achieving more efficient compression.

[0066] The LC3plus encoding manner is a superset of the LC3 encoding manner and includes all the functions of the LC3 encoding manner. In addition, the LC3plus encoding manner also has transmission robustness and a high-resolution encoding mode, and the data encoded by the LC3plus encoding manner can obtain a higher bit rate and a higher signal-to-noise ratio. At the same time, the LC3plus encoding manner also provides a flexible error concealment algorithm, which can optimize various audio signals and provide high-quality data transmission.

[0067] The APTX lossness coding mode is a lossless compression coding mode, which can provide a bit rate of up to 1 Mbps, and can also be smoothly reduced to 140 kbits and 16 bit / 44.1 kHz audio transmission in a crowded radio frequency environment, thereby minimizing audio interruption or interference, and bringing a CD-quality lossless audio experience. In order to save space, the process of encoding using the LC3plus coding mode and the APTX lossness coding mode in the present embodiment will not be discussed.

[0068] In addition, it should be noted that the broadcast data packet can also include the broadcast address of the broadcast device, the data size of the first data, and the like, and the broadcast device can also send an extension data packet before sending the broadcast data packet, the extension data packet including auxiliary information such as the transmission channel, the transmission time point, and the sound channel distribution of the broadcast data packet. Of course, the extension data packet and the broadcast data packet can be sent in no particular order, or can be sent as a whole.

[0069] In step S202, the first Bluetooth device does not support the first data to be played and cannot decode the first data, the first Bluetooth device supports the second data, the second data is encoded in a second coding mode supported by the first Bluetooth device, and the second coding mode refers to an encoding mode of data transmitted based on the A2DP (Advanced Audio Distribution Profile) protocol, that is, the first coding mode is different from the second coding mode. In order to enable the first Bluetooth device to play the broadcast data, it is necessary to convert the first data into the second data.

[0070] The encoding mode of the data transmitted based on the A2DP protocol includes multiple encoding modes, and different encoding modes can be used for different original data. For example, the original data f corresponds to the encoding mode F, and the original data e corresponds to the encoding mode E. It should be noted that the principle of the A2DP protocol is a Bluetooth protocol that allows wireless transmission of high-quality audio data to Bluetooth earphones, speakers, or other audio devices. The A2DP protocol can compress and encode audio data based on Bluetooth technology, and then wirelessly transmit the data to the receiving end for decoding and playing. Specifically, the encoding mode of the data transmitted based on the A2DP protocol can include an SBC (Sub-Band Coding) encoding mode, an AAC (Advanced Audio Coding) encoding mode, and the like. The basic principle of the SBC encoding mode is to divide the frequency of the audio signal into several sub-bands, and then independently encode each sub-band. Because the SBC encoding mode has a low bit rate and a high compression rate, the SBC encoding mode is an encoding mode supported by all Bluetooth devices. The AAC encoding mode can provide a large compression rate, thereby obtaining higher sound quality with smaller file size; can support multiple channels; can provide up to 48 full-range channels; has higher resolution; supports a maximum sampling frequency of 96kHZ; has higher decoding efficiency; and requires fewer resources for decoding and playing. The specific type of the second encoding mode in this embodiment can be set and selected according to the data type that the first Bluetooth device can support, as long as the first Bluetooth device can decode and play the second data after receiving the second data. The process of encoding the second data using the second encoding mode in this embodiment is a relatively mature encoding technology, and will not be discussed here.

[0071] In one example, the first encoding mode and the second encoding mode can be included in the broadcast data packet, that is, the first encoding mode and the second encoding mode are predetermined in the broadcast data packet, and the second data designated for the first Bluetooth device to play is encoded by the second encoding mode. For example, the first encoding mode G and the second encoding mode E are included in the broadcast data packet, and in the process of receiving the broadcast data packet of the broadcast device and performing data conversion processing by the terminal device, the second data can be directly determined based on the pre-stored first encoding mode G and the second encoding mode E.

[0072] In another example, the broadcast data packet can only include the first encoding mode, and the second encoding mode can be determined based on actual conditions, for example, the second encoding mode corresponding to the second data that can be played by the first Bluetooth device can be determined according to the performance of the first Bluetooth device, the data amount of the original data parsed by the first data, or the data conversion mode pre-stored by the terminal device.

[0073] During implementation, for example, the second encoding method can be determined based on the first encoding method. The terminal device has a pre-stored correspondence between the first encoding method and the second encoding method. If the first encoding method is LC3plus encoding method, the second encoding method can be determined to be AAC encoding method by querying the correspondence.

[0074] For example, the second encoding method can be determined based on the encoding parameters of the first and second encoding methods. If the code rate of the first encoding method is A, then encoding methods with a code rate less than A can be determined as the second encoding method. If there are multiple encoding methods with a code rate less than A, further selection can be made until a suitable second encoding method is determined.

[0075] For example, a second encoding method can be determined based on the first encoding method and the first data. The amount of data in the original data (original audio stream) can be determined using the first encoding method and the first data, thus determining the second encoding method. When the amount of data in the original data is large, AAC encoding is used; while when the amount of data in the original data is small, SBC encoding is used.

[0076] like Figure 3 The diagram shown is a block diagram of a data conversion device. Figure 3 The system includes a first encoder 31, a first decoder 32, a buffer 33, and a second encoder 34. The first encoder 31, located in the broadcasting equipment, is used to encode the raw data using a first encoding method to obtain first data. The first decoder 32, buffer 33, and second decoder 34 are all located in the terminal equipment. The first decoder 32 uses the same encoding and decoding method as the first encoder 31, and is used to decode the first data encoded by the first encoder 31 to obtain the raw data. The buffer 33 is used to store the raw data. The second encoder 34 is used to encode the raw data using a second encoding method to obtain second data. The raw data refers to pure audio stream data. Because the raw data is relatively large, it needs to be encoded (i.e., compressed) to ensure smooth data transmission, thereby reducing the data size and facilitating data transmission.

[0077] Combination Figure 3 As shown, the process of converting the first data into the second data is as follows:

[0078] The broadcast device encodes the original data by using the first encoder 31 to obtain the first data. The terminal device receives the first data and decodes the first data by using the first decoder 32 corresponding to the first encoder 31 to obtain the original data and stores the original data in the buffer area 33. The terminal device encodes the original data by using the second encoder 34 to obtain the second data supported by the first Bluetooth device for playing. For example, the broadcast data packet includes the first encoding mode as the LC3 encoding mode and the second encoding mode as the SBC encoding mode. In the application process, the broadcast device can directly encode the original data by using the LC3 encoder to obtain the first data, the terminal device can receive the first data and decode the first data by using the LC3 decoder corresponding to the LC3 encoder to obtain the original data, and encode the original data by using the SBC encoder to obtain the second data supported by the first Bluetooth device for playing.

[0079] It should be noted that when the second encoding mode needs to be determined additionally, the second encoder can be defined as an A2DP encoder, and the A2DP encoder includes a plurality of circuit corresponding to the encoding modes of the data transmitted based on the A2DP protocol and a selection switch. When the final second encoding mode is determined, the corresponding encoder circuit can be turned on by the selection switch. For example, when the final second encoding mode is determined as the SBC encoding mode, the selection switch can be connected with the SBC encoder circuit, so that the SBC encoder circuit is turned on. In addition, when the second encoding mode is included in the broadcast data packet, the encoder associated with the second encoding mode can be directly determined; or the second encoder can also be selected again according to the second encoding mode each time. In this way, the robustness and scalability of the second encoder can be improved to expand the application range of the second encoder.

[0080] It should be noted that the terminal device needs to decode the first data to obtain the original data and encode the original data to obtain the second data. If the decoding speed of the first data is less than the encoding speed of the original data, after the existing original data is encoded, the first data needs to be decoded, so that the playing process of the to-be-played data will appear the phenomenon of lag. Therefore, in the embodiment, the decoding speed of the first data is limited to be greater than the encoding speed of the original data, so that there is always original data in the encoding process, thereby avoiding the playing lag and improving the listening experience and use experience of the user.

[0081] In step S203, the second data is data that the first Bluetooth device supports playing, and correspondingly, in order to enable the first Bluetooth device to play the broadcast content, the first Bluetooth device is further provided with a second decoder corresponding to a second encoder to decode the second data to obtain the original data. By using the method in this embodiment, the first data that the first Bluetooth device does not support is converted into the second data that the first Bluetooth device supports, so that the first Bluetooth device successfully receives the broadcast data sent by the broadcast device without the need to replace the first Bluetooth device.

[0082] The embodiment can enable the first Bluetooth device to receive the broadcast data without the need of the user to replace the existing Bluetooth device, thereby saving the user's cost and improving the user's experience.

[0083] According to an exemplary embodiment, as shown in Figure 4 The communication method in this embodiment includes:

[0084] S401, receiving a broadcast data packet sent by a broadcast device.

[0085] S402, decoding the first data based on the first codec information to obtain the original data.

[0086] S403, encoding the original data in a second encoding manner to obtain second data.

[0087] S404, sending the second data to the first Bluetooth device.

[0088] The step S404 is the same as the step S203 in the above embodiment, and will not be described here.

[0089] In step S401, in one example, the broadcast data packet can only include the first codec information, and the first codec information is used to represent the first encoding manner, and can include encoding information of the first encoding manner or decoding information of a decoding manner corresponding to the first encoding manner, such as code rate, sampling rate (8kHz, 16kHz, 24kHz, 32kHz, 44.1kHz or 48kHz), frame interval (10ms or 7.5ms), data bit width (16bits, 24bits or 32bits) and the like.

[0090] In another example, the broadcast data packet can further include first codec information corresponding to the first encoding mode, and second codec information corresponding to the second encoding mode. The specific content of the first codec information can refer to the previous example, which will not be repeated here. Similarly, the second codec information for representing the second encoding mode can include encoding information of the second encoding mode or decoding information of a decoding mode corresponding to the second encoding mode, such as, encoding or decoding code rate, sampling rate (8 kHz, 16 kHz, 24 kHz, 32 kHz, 44.1 kHz or 48 kHz), channel mode (mono, stereo, stereo or joint stereo), block length (4, 8, 12 or 16), sub-band number (4 or 8), allocation mode, bit pool (range [2, 250]) and the like.

[0091] It should be noted that the encoding information and the decoding information in the first codec information or the second codec information should be corresponding, for example, the encoding code rate in the encoding information in the first codec information is A1, and the decoding rate in the decoding information in the first codec information is also A1; the sampling rate in the encoding information in the second codec information is A2, and the sampling rate in the decoding information in the second codec information is also A2, so as to ensure the consistency of the encoding process and the decoding process.

[0092] In step S402, the first codec information can be applied to the first decoder, so that the first decoder has the properties of the first codec information. Then, the first data is decoded by using the first decoder having the properties of the first codec information to obtain the original data. The decoding process using the first codec information is a relatively mature encoding technology, which will not be discussed here.

[0093] In step S403, in one example, when the second codec information is included in the broadcast data packet, the original data can be directly encoded based on the second codec information to obtain the second data. In another example, when only the first codec information is included in the broadcast data packet, the second codec information can be additionally determined based on actual conditions. For example, the second codec information can be determined based on the performance of the first Bluetooth device, the data amount of the original data parsed from the first data, or a corresponding relationship pre-stored by the terminal device. Specifically, the second codec information can be determined based on the first codec information. For example, the second codec information can be determined based on a corresponding relationship between the first codec information and the second codec information. For example, the first codec information X corresponds to the second codec information Y. If the current first codec information is the first codec information X, the second codec information can be determined as the second codec information Y. For another example, the second codec information can be determined based on the data amount of the original data decoded by using the first codec information. For example, the data amount of the original data can be determined by using the code rate or the sampling rate or other information in the first codec information, and the second codec information can be determined based on the data amount of the original data.

[0094] It should be noted that, regardless of the manner of determining the second codec information, the determined second codec information should have the properties of appropriate code rate and good listening experience, so as to ensure the user experience and listening experience. In the application process, if it is detected that the listening experience of the second data encoded based on the determined second codec information is poor (for example, the playback is interrupted, the playback is intermittent, etc.), the parameters in the second codec information can be adjusted based on actual conditions, for example, the code rate or the sampling rate or other parameters in the second codec information can be adjusted. In this way, the most appropriate second codec information can be determined by using the first codec information (and subsequent adjustment), so that the second data with smooth playback is obtained, and the listening experience of the user is improved.

[0095] In addition, it should be noted that the code rate of the first data is included in the first codec information, the code rate of the second data is included in the second codec information, based on the fact that the speed of decoding the first data by the terminal device is greater than the speed of encoding the original data, and in the process of encoding and decoding, the code rate can represent the size of data encoded by the encoder per second or the size of data decoded by the decoder per second, the code rate of the second data should be less than the code rate of the first data. Other information / parameters in the second codec information can be set and selected based on actual needs on the basis of ensuring the listening experience of the user, the A2DP protocol specification, and the good playback sound effect of the audio, which is not limited in the embodiment.

[0096] In addition, in order to further prevent the playing from being stalled, the original data decoded based on the first coding information can be stored in a cache area, and the original data is encoded based on the second coding information after the data amount of the original data reaches a certain threshold. In an example, the data amount of the original data stored in the cache area can be determined to correspond to a playing time length in the second encoding mode, and the original data is encoded based on the second coding information when the playing time length exceeds a preset threshold, to obtain second data. The specific value of the preset threshold is not limited in the embodiment, and the preset threshold can be 1s, 2s, etc.

[0097] In the embodiment, the first data can be decoded based on the first coding information to obtain original data, and the original data is encoded based on the second coding information to obtain second data, so as to realize the conversion between the first data and the second data. In this way, the first Bluetooth device that cannot originally listen to the broadcast can be used to listen to the broadcast, and the effect of using the first Bluetooth device to listen to the broadcast is achieved without the user needing to replace the existing Bluetooth device, thereby saving the user's money and improving the user's use experience.

[0098] According to an exemplary embodiment, as shown in Figure 5 The communication method in the embodiment includes:

[0099] S501, display the Bluetooth device that has established a connection based on the first instruction.

[0100] S502, determine the Bluetooth device selected for listening to the broadcast based on the first operation.

[0101] S503, judge the type of the selected Bluetooth device, if the type of the selected Bluetooth device is the second Bluetooth device, execute S504; if the type of the selected Bluetooth device is the first Bluetooth device, execute S505.

[0102] S504, send an operation instruction to the second Bluetooth device.

[0103] S505, start receiving the broadcast data packet.

[0104] S506, receive the broadcast data packet sent by the broadcast device.

[0105] S507, decode the first data based on the first coding information to obtain original data.

[0106] S508, encode the original data in the second encoding mode to obtain second data.

[0107] S509, send the second data to the first Bluetooth device.

[0108] Steps S506-S509 are the same as steps S401-S404 in the above embodiments, and will not be described again here.

[0109] In step S501, in one example, the first instruction can be used to represent a viewing instruction for a Bluetooth device that has established a connection with the terminal device. For example, it could be an instruction corresponding to a click operation on the parent interface of the interface containing the Bluetooth device that has established a connection with the terminal device; or an instruction corresponding to a long press operation on the Bluetooth icon in the status bar. After receiving the first instruction, the terminal device displays the interface containing the Bluetooth device that has established a connection. For example, refer to... Figure 6 The diagram shows a display interface of a terminal device. Figure 6 It includes a first Bluetooth device C1, a first Bluetooth device C2, a second Bluetooth device D1, and a second Bluetooth device D2.

[0110] Bluetooth devices are categorized into second Bluetooth devices and first Bluetooth devices, where the second Bluetooth device supports first data playback. That is, the second Bluetooth device is a device that supports broadcast listening technology. For example... Figure 7 The diagram shown illustrates one application scenario. Figure 7 exist Figure 1 The schematic diagram of the application scenario shown is supplemented by a second Bluetooth device. For the second Bluetooth device: the terminal device (i.e., the communication device using the method of this disclosure) can connect to at least one second Bluetooth device, and the second Bluetooth device can listen to the broadcast data sent by the broadcast device. Figure 7 The data flow direction is used to represent the relationship between the second Bluetooth device, the first Bluetooth device, the terminal device, and the broadcast device. It should be noted that the terminal device can select the second Bluetooth device as the broadcast listening device. Since the data flow direction between the two is not mentioned in this embodiment, therefore... Figure 7 The relationship between the second Bluetooth device and the terminal device will not be described for the time being.

[0111] In step S502, the first operation is used to select a Bluetooth device and instruct the selected Bluetooth device to listen to the broadcast content. The first operation can be a click, double-click, or voice operation, etc., and is not limited here. Taking a click operation as an example, when the user clicks on one of the Bluetooth devices (e.g., the second Bluetooth device D1), that Bluetooth device (the second Bluetooth device D1) is instructed to listen to the broadcast. Based on the characteristic that the second Bluetooth device D1 supports the playback of the first data, the second Bluetooth device can directly receive the broadcast data packets sent by the broadcast device, decode the first data to obtain the original data, and play it.

[0112] In step S503, since the first Bluetooth device and the second Bluetooth device are different types of Bluetooth devices, and the second Bluetooth device in the first Bluetooth device and the second Bluetooth device can support the first data playing, the first Bluetooth device does not support the first data playing, therefore, after the first operation, it is necessary to judge the type of the selected Bluetooth device, and corresponding data processing is carried out based on the type of the Bluetooth device. It should be noted that step S504 and step S505 are alternative selection.

[0113] In step S504, when the selected Bluetooth device is the second Bluetooth device, since the second Bluetooth device supports the first data playing, an operation instruction can be sent to the second Bluetooth device, and the operation instruction is used to instruct the second Bluetooth device to receive the broadcast data packet sent by the broadcast device. After receiving the broadcast data packet, the second Bluetooth device can decode the first data, and then obtain the original data and perform audio playing.

[0114] In step S505, when the selected Bluetooth device is the first Bluetooth device, since the first Bluetooth device does not support the first data playing, the terminal device will start receiving the broadcast data packet, and send the first data in the broadcast data packet to the first Bluetooth device after processing. In this way, it can be ensured that the user can use the first Bluetooth device as an audio playing device to listen to the broadcast content of the broadcast device.

[0115] The embodiment shows the way of obtaining the original data corresponding to the first Bluetooth device and the second Bluetooth device, which are two different types of Bluetooth devices. In this way, the application range of the method shown in the embodiment can be expanded, so that the method shown in the embodiment is applicable to a variety of Bluetooth devices.
