The electronic device 100 can perform bluetooth connection with a bluetooth device 200 (e.g., an audio playing device such as a bluetooth headset or a bluetooth sound box, or a video playing device such as a projector or a television) through a bluetooth module; the electronic device 100 may also perform a WiFi connection through a WiFi module, for example, the electronic device 100 connects to a wireless local area network through the WiFi module to perform data interaction with a server 300 (e.g., a cloud server, a mobile phone, a computer, a tablet computer, etc.), as shown in fig. 1.
As the demand of users for electronic devices increases, the electronic devices start to support playing audio data in order to meet the demands of users and provide convenience for users, wherein the audio architecture of the electronic devices is similar to that of computers, and is mainly completed by processors and built-in audio CODECs (CODECs). Specifically, the processor receives the input of audio data, converts the audio data into an I2S signal, transmits the I2S signal to the CODEC, converts the I2 signal into an analog signal, and plays the analog signal.
Further, the electronic device may be connected to an external audio playing device, and the audio playing device plays audio data, specifically, the audio playing device may receive the audio data transmitted by the electronic device and play the audio data, where the audio playing device may include an earphone, a sound box, a vehicle-mounted device, and the like. In many cases, the electronic device and the external audio playing device need to use a network for data transmission, for example, the electronic device and the audio playing device need to use a Wireless Fidelity (WiFi) connection for data transmission, or the electronic device and the audio playing device need to use a Bluetooth (BT) connection for data transmission, and optionally, in a general case, the electronic device may be connected with the audio playing device through Bluetooth, and transmit the audio data to the audio playing device through Bluetooth for playing.
The electronic equipment at present generally comprises a Bluetooth module and a WiFi module, the electronic equipment can be connected to audio playing equipment such as a Bluetooth headset through the Bluetooth module, music playing is carried out on the electronic equipment, then audio data are transmitted to the audio playing equipment through Bluetooth, and the audio playing equipment receives the audio data and outputs the audio data. However, the WiFi of the electronic device supports a 2.4G band and a 5G band, wherein the WiFi2.4G band and the bluetooth 2.4G band overlap, and the WiFi and the bluetooth share a radio frequency antenna, so if both the bluetooth and the WiFi use the 2.4G band, there is a problem of preempting antenna resources, i.e. a problem of BT/WiFi coexistence, thereby causing a problem of audio data blockage.
In view of the above problems, the inventors have found through long-term research and propose a data transmission method, an apparatus, an electronic device, and a storage medium provided in the embodiments of the present application, where a first antenna and a second antenna that are independent of each other are preset, and when a 2.4G frequency band of the first antenna is used by WiFi, bluetooth audio data is transmitted through the second antenna, so as to avoid the problem of coexistence of bluetooth and WiFi, reduce the number of audio data cards, and improve the reliability of data transmission. The specific data transmission method is described in detail in the following embodiments.
Examples
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a data transmission method according to an embodiment of the present application. The data transmission method is used for transmitting Bluetooth audio data through the second antenna by presetting the first antenna and the second antenna which are independent from each other and when the 2.4G frequency band of the first antenna is used by WiFi, so that the problem of coexistence of Bluetooth and WiFi is avoided, the audio data jamming is reduced, and the data transmission reliability is improved. In a specific embodiment, the data transmission method is applied to the data transmission apparatus 400 shown in fig. 8 and the electronic device 100 (fig. 9) configured with the data transmission apparatus 400. The specific flow of the embodiment will be described below by taking an electronic device as an example, and it is understood that the electronic device applied in the embodiment may be a smart phone, a tablet computer, a wearable electronic device, a vehicle-mounted device, a gateway, and the like, and is not limited specifically herein. As will be described in detail with respect to the flow shown in fig. 2, the data transmission method may specifically include the following steps:
step S101: when the electronic equipment runs with a target application program, the working state of the first antenna is detected, and the target application program at least supports the playing of audio data.
Referring to fig. 2, in the present embodiment, the electronic device includes a first antenna a and a second antenna B, where the first antenna a and the second antenna B are disposed independently from each other, and as a mode, the first antenna a and the second antenna B are both connected to a main board of the electronic device and disposed at a certain distance on the main board, for example, the first antenna a and the second antenna B are disposed at a distance of 3mm, and in addition, the first antenna a and the second antenna B include but are not limited to a printed antenna, an assembly structure, and the like. Further, the first antenna a supports at least a 2.4G frequency band and a 5G frequency band, so that when the first antenna a is in the operating mode, the electronic device can be operated in the bluetooth mode, the WiFi mode, or both the bluetooth mode and the WiFi mode; the second antenna B supports at least a 2.4G frequency band, that is, the second antenna B may be an independent bluetooth antenna, so when the second antenna B is in an operating state, the electronic device may operate in a bluetooth mode, a WiFi mode, or a bluetooth mode simultaneously, and it can be understood that when the first antenna a and the second antenna B are in an operating state simultaneously, the electronic device may be in a WiFi mode through the first antenna a, and the electronic device may be in a bluetooth mode through the second antenna B, so that BT/WiFi coexistence of the electronic device may be achieved.
In this embodiment, the application program of the electronic device may include an application program running in the foreground of the electronic device, an application program running in the background of the electronic device, or an application program that is switched to run in the foreground and the background of the electronic device. Specifically, an application program running in the foreground refers to an application program which can generally interact with a user and can run in the foreground, and the application program can be suspended when the application program is not visible (such as games); background running applications mean very limited interaction with the user, except during configuration, where other times of the lifetime are hidden (e.g., SMS auto-answer program and alarm clock program); the application program which is switched to run in the foreground and the background of the electronic equipment refers to the application program which can be switched between the foreground and the background at will. It is understood that when an application is not killed (kill), the application is characterized as running on the electronic device.
Further, a target application is determined from the applications run by the electronic device, where the target application may include a single application or may include multiple applications, and is not limited herein. In this embodiment, the target application at least supports playing of audio data, that is, the target application has at least audio output, for example, the target application may include a music playing application, a video playing application, a conversation application, a game application, and the like, and the application may output audio data, or may output audio data and image data at the same time.
Further, when it is detected that the electronic device runs the target application program, the operating state of the first antenna is detected, and it can be understood that the operating state of the first antenna at least may include a network connection state, a network disconnection state, and a network connection in-progress state, where when the first antenna is in the network connection state, it may be characterized that the first antenna is in the operating mode, and further, a use state of the first antenna when the first antenna is in the operating mode is detected. As one way, when the first antenna is in a network connection state, the first antenna may be in a mobile network connection state, for example: in a 4G network connection state, in a 3G network connection state or in a 2G network connection state; the first antenna may be in a wireless network connected state, for example: in a WiFi connection state or in a MiFi connection state; the electronic device may also be in a bluetooth connection state, and the like, which is not limited herein.
Step S102: when the electronic equipment is connected to audio playing equipment through Bluetooth, whether the 2.4G frequency band of the first antenna is used by WiFi is judged according to the working state.
As one mode, in this embodiment, the audio playing device may include a bluetooth module, and the audio playing device may perform bluetooth connection with the electronic device through the bluetooth module. When it is detected that the electronic device is connected to the audio playing device through bluetooth, for example, when it is detected that both the electronic device and the audio playing device are powered on bluetooth and the electronic device and the audio playing device are successfully paired, it may be characterized that the electronic device is connected to the audio playing device through bluetooth.
It can be understood that, in this embodiment, it may also be detected whether the device connected to the electronic device through bluetooth is an audio playing device, wherein, in the electronic device based on the android operating system, the device type currently connected through bluetooth may be determined by a return value obtained based on instantiating the bluetooth class. If the returned value is AUDIO _ VIDEO _ CAMCORDER, the image acquisition equipment is characterized; if the returned value is AUDIO _ VIDEO _ CAR _ AUDIO, the vehicle-mounted equipment is characterized; if the returned value is AUDIO _ VIDEO _ HIFI _ AUDIO, the AUDIO or VIDEO playing device is characterized as an AUDIO playing device or a VIDEO playing device, such as a bluetooth headset; if the returned value is AUDIO _ VIDEO _ MICROPHONE, it is characterized as a MICROPHONE.
When the electronic equipment is determined to be connected to the audio playing equipment through the Bluetooth, whether the 2.4G frequency band of the first antenna is used by the WiFi is judged based on the working state of the first antenna obtained through current detection. Specifically, when the first antenna is in the working state, it is first detected whether the first antenna is in the WiFi connection state, and if it is detected that the first antenna is in the WiFi connection state, it is detected whether the frequency band used by the WiFi is a 5G frequency band or a 2.4G frequency band, so as to determine whether the WiFi is using the 2.4G frequency band of the first antenna.
Step S103: when the 2.4G frequency band of the first antenna is being used by the WiFi, the electronic equipment is controlled to transmit the audio data to the audio playing equipment through the second antenna.
The audio data output by the electronic device may be obtained locally from the electronic device, or may be obtained from a server through a network, which is not limited herein. After the electronic device obtains the audio data from the local or the server, the audio data is subjected to audio decoding, audio processing and Bluetooth CODEC encoding processing, and then transmitted to an audio playing device for output. When the 2.4G frequency band of the first antenna is determined to be being used by WiFi, it is characterized that the WiFi is using the first antenna resource, so that if the audio data is transmitted to the audio playing device through the first antenna at this time, sufficient first antenna resource may not be allocated, so that the audio data transmission is slow, the audio data is jammed, and the user experience is poor. Therefore, in this embodiment, when it is determined that the 2.4G band of the first antenna is being used by WiFi, the electronic device is controlled to transmit the audio data to the audio playing device through the second antenna, and since the 2.4G band of the second antenna is not being used by WiFi, the coexistence problem of bluetooth and WiFi is avoided, the jamming of the audio data is reduced, and the reliability of data transmission is improved.
According to the data transmission method provided by one embodiment of the application, when the electronic device runs with a target application program, the working state of the first antenna is detected, the target application program at least supports playing of audio data, when the electronic device is connected to the audio playing device through bluetooth, whether the 2.4G frequency band of the first antenna is used by WiFi is judged according to the working state, when the 2.4G frequency band of the first antenna is used by WiFi, the electronic device is controlled to transmit the audio data to the audio playing device through the second antenna, therefore, by presetting the first antenna and the second antenna which are independent of each other, and when the 2.4G frequency band of the first antenna is used by WiFi, the bluetooth audio data is transmitted through the second antenna, so that the problem of coexistence of bluetooth and WiFi is avoided, audio data cards are reduced, and data transmission reliability is improved.
Referring to fig. 4, fig. 4 is a flowchart illustrating a data transmission method according to another embodiment of the present application. The method is applied to the electronic device, and will be described in detail with respect to the flow shown in fig. 4, and the method may specifically include the following steps:
step S201: and detecting whether the foreground of the electronic equipment runs an application program supporting the playing of the audio data.
In this embodiment, the application program running in the foreground of the electronic device is detected, and then it is determined whether the application program running in the foreground supports playing of the audio data. Specifically, the foreground application may be identified, for example, the application information is identified as a video playing application, a music playing application, or a novel viewer application, and then whether the foreground application supports playing of audio data is determined according to the application information obtained by identification.
Step S202: and when the foreground runs the application program supporting the playing of the audio data, taking the application program running in the foreground as the target application program.
As one way, when it is determined that the foreground-running application supports the playing of audio data, the foreground-running application is taken as the target application.
Step S203: and when the foreground does not run the application program supporting the playing of the audio data, searching the application program supporting the playing of the audio data from the application programs running in the background to be used as the target application program.
As another way, when it is determined that the application program running in the foreground of the electronic device does not support the playing of the audio data or the application program is not running in the foreground of the electronic device, a plurality of application programs running in the background of the electronic device are correspondingly acquired, and the application program supporting the playing of the audio data is searched for as the target application program among the plurality of application programs. It is to be understood that there is generally one application capable of outputting audio data running in the background, and if there are a plurality of applications capable of outputting audio data running in the background, one of the applications is selected as the target application.
Step S204: when the electronic equipment runs with a target application program, the working state of the first antenna is detected, and the target application program at least supports the playing of audio data.
Step S205: when the electronic equipment is connected to audio playing equipment through Bluetooth, whether the 2.4G frequency band of the first antenna is used by WiFi is judged according to the working state.
Step S206: acquiring an encoding rate of the audio data when the 2.4G band of the first antenna is being used by the WiFi.
As one way, when the 2.4G band of the first antenna is being used by WiFi, the encoding rate of the audio data output by the electronic device is correspondingly obtained. It is understood that, after receiving the audio data, the processor converts the audio data into an I2S signal, and transmits the signal to the encoder for encoding, wherein, a plurality of encoding types are corresponding in the encoder, and each encoding type has a different encoding rate, further, when the encoding rate of the audio data is higher, the sound quality of the audio data is better represented, the amount of data to be transmitted is larger, and when the encoding rate of the audio data is lower, the sound quality of the audio data is worse represented, the amount of data to be transmitted is smaller.
In this embodiment, the signal quality is positively correlated with the coding rate, that is, the better the signal is, the larger the corresponding coding rate is, that is, after sampling, quantizing, and encoding the analog signal is completed, the larger the proportion of the useful information part in the data stream is; conversely, the worse the signal, the smaller the corresponding coding rate, i.e. the smaller the proportion of useful information in the data stream after sampling, quantizing and coding the analog signal.
Specifically, the increase of the coding rate may be to increase the sampling rate, or to reduce the useless information and retain more useful information during the coding process, i.e. to reduce the compression ratio, for example, an encoding algorithm that stores 16-bit data of each sample in the audio stream at 4-bit, the compression ratio is 4: 1, 25% of the useful information is retained, and if the compression ratio is changed to 8 bits, the compression ratio is changed to 2:1, the compression ratio is reduced, and 50% of the useful information is retained, more useful information is retained, but the data amount of the audio data becomes larger.
Step S207: and judging whether the encoding rate is higher than a preset encoding rate.
The electronic device is preset and stored with a preset encoding rate, the preset encoding rate is used as a judgment basis for the encoding rate of the audio data, therefore, after the encoding rate of the audio data is obtained, the encoding rate is compared with the preset encoding rate to judge whether the encoding rate is higher than the preset encoding rate, it can be understood that when the encoding rate is higher than the preset encoding rate, the data quantity representing the encoding rate is higher than the preset data quantity, and the transmission needs to be completed by occupying a larger antenna resource, and when the encoding rate is not higher than the preset encoding rate, the data quantity representing the encoding rate is not higher than the preset data quantity, and the transmission can be completed by needing a smaller antenna resource.
Step S208: and when the encoding rate is higher than the preset encoding rate, controlling the electronic equipment to transmit the audio data to the audio playing equipment through the second antenna.
Further, in this embodiment, when the encoding rate is higher than the preset encoding rate, the audio data corresponding to the encoding rate needs to occupy a larger antenna resource for transmission, but the 2.4G band of the first antenna is being used by WiFi, so the electronic device can be controlled to transmit the audio data to the audio playing device through the second antenna, and it can be understood that, since the 2.4G band of the second antenna is only used by bluetooth, the audio data can be transmitted to the audio playing device quickly and stably.
Step S209: and when the encoding rate is not higher than the preset encoding rate, controlling the electronic equipment to transmit the audio data to the audio playing equipment through the first antenna.
Further, in this embodiment, when the encoding rate is not higher than the preset encoding rate, the audio data corresponding to the encoding rate does not need to occupy a larger antenna resource for transmission, and therefore, as a mode, even if the 2.4G frequency band of the first antenna is being used by WiFi, the audio data transmission will not be greatly affected, and the electronic device is controlled to transmit the audio data to the audio playing device through the first antenna, so that power consumption of the electronic device caused by simultaneous operation of the first antenna and the second antenna can be reduced.
Step S210: and when the encoding rate is not higher than the preset encoding rate, increasing the encoding rate to obtain the current encoding rate, and adjusting the audio data according to the current encoding rate to obtain the current audio data, wherein the current encoding rate is higher than the preset encoding rate.
As another way, when the encoding rate is not higher than the preset encoding rate, the sound quality characterizing the audio data is poor, and therefore, the encoding rate may be increased to obtain the current encoding rate, and of course, in the present embodiment, the current encoding rate obtained by increasing is higher than the preset encoding rate. Then, the audio data is adjusted according to the current encoding rate to obtain the current audio data, and it can be understood that the sound quality of the current audio data obtained after the adjustment is better than that of the audio data before the adjustment.
Step S211: and controlling the electronic equipment to transmit the current audio data to the audio playing equipment through the second antenna.
Furthermore, the electronic device is controlled to transmit the current audio data to the audio playing device through the second antenna, and when the encoding rate of the current audio data is higher than the preset encoding rate, the current audio data is represented to occupy a larger antenna resource for transmission, but the 2.4G frequency band of the first antenna is being used by WiFi, so that the electronic device can be controlled to transmit the current audio data to the audio playing device through the second antenna.
In another embodiment of the present application, when the foreground runs the application program supporting the playing of the audio data, the foreground runs the application program as a target application program, when the foreground does not run the application program supporting the playing of the audio data, the application program supporting the playing of the audio data is searched from the application programs running in the background as the target application program, when the electronic device runs the target application program, the operating state of the first antenna is detected, when the electronic device is connected to the audio playing device through bluetooth, whether the 2.4G band of the first antenna is being used by WiFi is determined according to the operating state, when the 2.4G band of the first antenna is being used by WiFi, the encoding rate of the audio data is obtained, and when the encoding rate is higher than the encoding rate preset, the electronic device is controlled to transmit the audio data to the audio playing device through the second antenna, when the encoding rate is not higher than the preset encoding rate, the electronic device is controlled to transmit the audio data to the audio playing device through the first antenna, or the encoding rate is increased to obtain the current encoding rate, the audio data is adjusted according to the current encoding rate to obtain the current audio data, the current encoding rate is higher than the preset encoding rate, and the electronic device is controlled to transmit the current audio data to the audio playing device through the second antenna.
Referring to fig. 5, fig. 5 is a schematic flowchart illustrating a data transmission method according to still another embodiment of the present application. As will be explained in detail with respect to the flow shown in fig. 5, the method may specifically include the following steps:
step S301: when the electronic equipment runs with a target application program, the working state of the first antenna is detected, and the target application program at least supports the playing of audio data.
Step S302: when the electronic equipment is connected to audio playing equipment through Bluetooth, whether the 2.4G frequency band of the first antenna is used by WiFi is judged according to the working state.
Step S303: when the 2.4G frequency band of the first antenna is being used by the WiFi, the electronic equipment is controlled to transmit the audio data to the audio playing equipment through the second antenna.
