Whether the equipment that can also pass through bluetooth connection to electronic equipment is that audio-frequence player device detects, wherein It, can be as obtained by Case-based Reasoning BluetoothClass.Device class in electronic equipment based on android operating system To return value determine the currently device type by bluetooth connection.If the value returned is AUDIO_VIDEO_CAMCORDER, Then it is characterized as image capture device；If the value returned is AUDIO_VIDEO_CAR_AUDIO, it is characterized as mobile unit；If returning The value returned is AUDIO_VIDEO_HIFI_AUDIO, then audio-frequence player device or video playback apparatus is characterized as, for example, bluetooth Earphone；If the value returned is AUDIO_VIDEO_MICROPHONE, it is characterized as microphone.

When determining that electronic equipment connects wireless audio playback equipment, that is to say, that wireless in electronic equipment connection After audio-frequence player device, whether the audio playing module for detecting electronic equipment receives playing request, which is to use In the request of request playing audio-fequency data.

Wherein, audio playing module can be the audio playing program of electronic equipment.Specifically, in electronic equipment and wirelessly Audio-frequence player device connect when, and need for audio data to be played to be sent to wireless audio play play when, which broadcasts Audio data coding can be got audio data in electronic equipment, and need the loudspeaking by electronic equipment by amplification module When device plays, which can decode audio data and be sent to loudspeaker and play out.

Specifically, which can be pure audio files, can also broadcasting corresponding with image data audio data, For example, being the audio data in video, specifically, video data includes the sound of image data and broadcasting corresponding with image data Frequency evidence includes specifically multiple image data and audio data in video, when video data plays, spininess figure As data are as shown by the display device of electronic equipment or the peripheral hardware display device connecting with electronic equipment, and audio data by Audio player, for example, wireless audio playback equipment plays, specifically, in the play time pair of a certain frame of image data Answer the play time of an audio data.And the audio data in game is also similar, audio data needs and game Interior game picture is corresponding to be played.

Then when electronic equipment plays the video in pure audio files or video file and scene of game, audio is played Module gets the playing request of audio data to be played, can get audio data by parsing the playing request.

Specifically, playing request can be prompting message, be also possible to voice playing request.Wherein, prompting message includes The letter that call-prompting information, short message prompting message and clock alarming information etc. are used to remind the certain events of user triggered Breath.For example, call-prompting information is for reminding user currently to have incoming call.

As another embodiment, sounding request can be during electronic equipment sounding, play voice every time Request.Then sounding request can be the request of audio sounding, be also possible to the request of video sounding or call sounding request.

Specifically, multiple audio playing softwares are installed, then the software can be music APP, view in electronic equipment Frequency plays APP or recording APP etc..For example, video playing interface is provided with video playing key, by pressing to the video playing The detection of the touch-control of key, can determine whether the audio playing module of electronic equipment currently receives the broadcasting of audio data and ask It asks, for example, user chooses video, into the broadcast interface of video, clicks the broadcast button of the broadcast interface, application program passes through Monitoring to user's touch control operation, be able to detect that user currently clicked is what kind of video, and specifically, broadcasting is pressed Button is provided with preset attribute, detects the attribute of the acquired corresponding broadcast button of touch control operation, it will be able to determine user institute The video to be played chosen, and then get playing request and the corresponding audio of the playing request.

S202: the encoding rate for the audio data to be sent to the wireless audio playback equipment is determined.

When audio data is sent to wireless audio playback equipment by electronic equipment, for the speed of improve data transfer, need By Audio data compression, to reduce the size of audio data, then the process is to encode to audio data.Specifically, There are a variety of for the audio data to be sent to the encryption algorithm of the wireless audio playback equipment, each encryption algorithm institute Corresponding encoding rate is different, i.e., sound when different encryption algorithms is to the same audio data coding, after obtained coding The size of frequency evidence is also different.

Wherein, electronic equipment is sent to what wireless audio playback equipment played to by sound from the sound that user inputs is received Process, including analog signal sampling, quantization and the coding to sound.Sound is the signal of Time Continuous, by the sound The digitlization of the signal, i.e. discretization are realized in sampling and quantization, to form audio data.For example, when if sound is one Between continuous sine curve, after electronic equipment gets the sound, for example, pass through microphone acquire.Electronic equipment is to this Sampled voice is at several points, this process is sampling.Obviously, sampling density is bigger, i.e., sample rate is bigger, obtained discrete Signal is just closer to former continuous signal.Since each sampled point will occupy memory space, therefore sample rate is higher, gained The audio data arrived is bigger.

Sampling is the first step of audio processing.After sampling, also the data of acquisition are stored.Storage is desirable Space, one second sampled data is stored with how many space, and here it is audio coding rates.As it can be seen that identical in sample rate Under the premise of, encoding rate is lower, and data are smaller.But two steps of sampling and coding can all reduce sound quality.Coding is actually Compression, encoding as mp3 is all lossy compression, thrown away most of human ear discover without sonic data, thus volume Very little.

Wherein, the raising of audio coding rate can be raising sample rate, be also possible to during coding, reduce nothing Discarding and the more useful informations of reservation with information, i.e. reduction compression ratio, for example, a kind of encryption algorithm, it will be in sound stream The 16bit data sampled every time are stored with 4bit, then compression ratio is 4:1, then have 25% useful information to be retained, and if will Compression ratio becomes 8bit, then compression ratio becomes 2:1, and compression ratio is reduced, and has 50% useful information to be retained, and more has It is retained with information, but the data quantitative change of audio data is bigger.

The above are in the cataloged procedure of sound to audio data, then after getting audio data, need audio number According to by Bluetooth transmission to wireless audio playback equipment, and in order to guarantee the speed of data transmission, need in accordance with electronic equipment with Bluetooth transmission protocol between wireless audio playback equipment is by audio data coding, to form the format of user's transmission, for example, on State by pcm encoder at SBC format, and in order to improve transmission speed and improve transmission serious forgiveness, need to adopt audio data Sample and coding, so that the size of audio data is reduced, convenient for transmission.Coding when similarly, for for transmitting audio data Rate increases, and can increase the compression ratio in the transmission to the sample rate of audio data or when reducing coding.

And which kind of specifically used encoding rate of electronic equipment is used to audio data being sent to the wireless audio playback equipment, It can be what user was actively arranged, be also possible to using access times in encoding rate used in the last time or preset time period Higher encoding rate, for example, it may be connecting electronic equipment with wireless audio playback equipment in user is to have set to be used for Audio data is then sent to the nothing in electronic equipment using the encoding rate as default code rate by the encoding rate of audio transmission When line audio-frequence player device, just by audio data coding and transmitted using the default code rate.

S203: according to the corresponding relationship of preset bandwidth and encoding rate, the electronic equipment and the wireless audio are improved The bandwidth of destination data link between playback equipment.

Assuming that electronic equipment is when being sent to the wireless audio playback equipment for audio data, using the encoding rate Audio data coding is generated into packets of audio data, and different encoding rates, packets of audio data size generated are also different.And needle The data packet big to some data volumes needs to increase bandwidth and sends by the data packet, and otherwise, bandwidth is too low, each institute's energy The maximum amount of data of transmission is too small, will lead to that the speed of transmitted data is excessively slow and Caton occurs in cause audio to play when The phenomenon that.

As an implementation, it can be the corresponding relationship according to preset bandwidth and encoding rate, improve the electronics The bandwidth of destination data link between equipment and the wireless audio playback equipment, wherein in the corresponding relationship, the bandwidth Size and the encoding rate height be positively correlated, that is to say, that bandwidth is bigger, then encoding rate is higher.

Specifically, the corresponding relationship is as shown in table 1 below:

Table 1

Bandwidth	Encryption algorithm
		1MHz	SBC
2MHz	ACC
		3MHz	APTX
4MHz	LDAC

In table 1 as above, SBC, ACC, APTX and LDAC are several different encryption algorithms, i.e. audio data is passed by bluetooth Format when defeated, and in upper table 1, from top to bottom, encoding rate is gradually increased, i.e. encoding rate: SBC < ACC < APTX < LDAC, and Corresponding bandwidth is also to be gradually increased.

Specifically, when audio data is sent to wireless audio playback equipment using bluetooth, bluetooth mould can be configured Bluetooth transmission parameter in block, the Bluetooth transmission parameter include transmission power, transmission rate and bandwidth etc., pass through reading as a result, The Bluetooth transmission parameter is taken just to can determine target data between presently described electronic equipment and the wireless audio playback equipment The bandwidth of link.

Then, after determining the corresponding bandwidth of encoding rate by above-mentioned corresponding relationship, by the bandwidth found with work as Preceding bandwidth is found the current Bandwidth adjustment for example, if the band found, which is wider than, is deserved preceding bandwidth Bandwidth, for example, the corresponding encryption algorithm of encoding rate for the audio data to be sent to the wireless audio playback equipment For LDAC, then corresponding bandwidth is 4MHz, and current bandwidth is 2MHz, then 4MHz is greater than 2MHz, then by current Bandwidth adjustment For 4MHz.

As another embodiment, it is set for the audio data to be sent to wireless audio broadcasting having determined Standby encoding rate, judges whether the encoding rate belongs to pre-arranged code rate, if so, by the electronic equipment and the wireless audio The bandwidth of destination data link improves between playback equipment, and specifically, the amplitude of raising can be a preset fixation Value is also possible to the corresponding relationship according to shown in above-mentioned table 1 and is adjusted for example, fixed improve 4MHz.

Wherein, pre-arranged code rate is the corresponding encoding rate of preset several different types of encryption algorithms, for example, in advance If encoding rate is that APTX and LDAC is not belonging to the pre-arranged code rate, does not then need to improve then if present encoding rate is SBC The bandwidth of destination data link between the electronic equipment and the wireless audio playback equipment, if present encoding rate is LDAC then belongs to the pre-arranged code rate, then improves target data between the electronic equipment and the wireless audio playback equipment The bandwidth of link.

S204: by the destination data link after raising bandwidth, the audio data is sent to the wireless audio and is broadcast Put equipment.

After audio data is encoded according to encryption algorithm, packets of audio data is generated, by the destination data link by sound Frequency data packet is sent to the wireless audio playback equipment, so as to realize that audio data, which is sent to wireless audio broadcasting, to be set It is standby.

Due to improving the bandwidth of destination data link between electronic equipment and the wireless audio playback equipment, so that often The data volume of the secondary data that can be transmitted is bigger, so as to which audio data is sent to wireless audio playback equipment faster, Enable wireless audio playback equipment continue and high speed acquisition audio data, avoid because wait audio data reception and Lead to the Caton in audio data playing process, further, it is possible to higher encoding rate be supported, so that the sound quality of audio data is more It is high.

Furthermore, it is contemplated that destination data link is used between the electronic equipment and the wireless audio playback equipment Communications band and other data link when share, the resource due to the communications band is seized, and is easier to cause The bandwidth of destination data link is insufficient, therefore, for the shared situation of communications band, the band of destination data link can be improved Width, specifically, as shown in figure 3, this method comprises: S301 to S305.

S301: when electronic equipment connects wireless audio playback equipment, the audio playing module of the electronic equipment is detected Whether the playing request of audio data is received.

S302: the encoding rate for the audio data to be sent to the wireless audio playback equipment is determined.

S303: communications band used in the destination data link is determined.

When electronic equipment is connect with external wireless device, electronic equipment selects bluetooth, WiFi or other connection types Connection request is sent to external wireless device, then can be searched in the frequency range for the communication mode that external wireless device is supported The external wireless device, for example, electronic equipment opens bluetooth, then in the corresponding communications band of bluetooth, e.g. 2.4GHz, energy Enough search the external equipment for also opening bluetooth.

Specifically, after connection, electronic equipment can determine electronic equipment for electronic equipment and wireless audio playback equipment Set used communication mode, e.g. bluetooth with wireless audio broadcasting, then electronic equipment and wireless audio playback equipment it Between data communication need the antenna of electronic equipment to send data to wireless audio playback equipment, or receive wireless audio and broadcast Data transmitted by equipment are put, and frequency range used in different communication modes is different, such as bluetooth uses 2.4GHz, 2.4GHz or 5GHz can be used in WiFi.After then selecting a kind of communication mode, it will be able to determine that the communication mode is corresponding logical Believe frequency range, for example, bluetooth corresponds to 2.4GHz, and electronic equipment is passing through corresponding to the router or hot spot that WiFi is connected Frequency range is different, then corresponding communications band is also different, for example, scanning the WiFi heat of surrounding after electronic equipment opens WiFi Point obtains WiFi list, as shown in figure 4, showing the mark of multiple hot spots in the list, wherein some hot spots are corresponding Communications band is 2.4GHz, and the corresponding communications band of some hot spots is 5GHz, and in Fig. 4, the corresponding communications band of WiFi-1 is The corresponding communications band of 2.4GHz, WiFi-1-5GHz is 5GHz, then user selects WiFi-1, then electronic equipment and WiFi-1 it Between connected by the communications band of 2.4GHz, and if user selects WiFi-1-5GHz, lead between electronic equipment and WiFi-1 Cross the communications band connection of 5GHz.Electronic equipment just can determine between electronic equipment and the Wi-Fi hotspot connected as a result, Communications band.

S304: if there is other data link and the destination data link share the communications band, then according to default Bandwidth and encoding rate corresponding relationship, improve target data chain between the electronic equipment and the wireless audio playback equipment The bandwidth on road.

When electronic equipment and wireless audio playback equipment has been determined, it can determine that the electronic equipment and wireless audio play Connection type and destination data link between the two between equipment, thus just can determine electronic equipment and wireless audio The corresponding communications band of destination data link between playback equipment.Then, then determine whether that other data link make With the communications band.

As an implementation, electronic equipment includes bluetooth module and WiFi module.

The WiFi module is for realizing the connection between WiFi access point, and the data friendship between WiFi access point Mutually.Specifically, can with peripheral apparatus by adopting wireless fidelity technology (Wireless, Fidelity, WiFi) (such as U.S. electric and Electronic Engineering Association standard IEEE 802.10A, IEEE802.11b, IEEE802.11g and/or IEEE 802.11n) agreement Communication connection is established, then WiFi module may include power amplifier, wireless transceiver, transmit/receive switch, low-noise amplifier And antenna etc..When sending signal, transceiver itself can directly export low power faint radiofrequency signal, send to power amplification Device (Power Amplifier, PA) carries out power amplification, then passes through transmit/receive switch (Transmit/Receive Switch) space is radiated to via antenna (Antenna).When receiving signal, antenna can sense the electromagnetic signal in space, lead to It crosses after switch to send to low-noise amplifier (Low Noise Amplifier, LNA) and amplify, in this way, amplified letter Number can be directly fed to transceiver is handled, and is demodulated.The first communications band and second can be used in the WiFi module Communications band, wherein the first communications band can be 2.4GHz, and the second communications band can be 5Ghz.

Similarly, bluetooth module is for realizing the bluetooth connection between electronic equipment and bluetooth equipment, and and bluetooth equipment Between data interaction.Specifically, can also lead to bluetooth equipment by Bluetooth protocol 5.0/4.2/4.1/2.1/2.0 Cross bluetooth low energy consumption technologies (Bluetooh Low Energy, BLE), bluetooth enhancing rate technology (Enhanced Data Rate, EDR) or bluetooth basic rate (Base Rate, BR) etc..Its basic circuit constitute it is similar with WiFi module, can also be with It is made of power amplifier, wireless transceiver, transmit/receive switch, low-noise amplifier and antenna etc..The bluetooth module can be with Use the first communications band.

When the bluetooth module and WiFi module of electronic equipment work at the same time, and WiFi module using the first communications band when It waits, will lead to bluetooth module and WiFi module simultaneously in the communications band using 2.4GHz, therefore, as shown in figure 5, the tool of S304 Body embodiment may include step S3041 to S3042.

When electronic equipment passes through bluetooth connection wireless audio playback equipment, then electronic equipment and wireless audio can be determined Destination data link between playback equipment, and determine that the corresponding communications band of change destination data link is the first communication frequency Section, the i.e. communications band of 2.4GHz.

Then, it then executes S3401: judging whether the WiFi module is used first communications band.

Judge whether electronic equipment passes through WiFi module and connect with external equipment (for example, wireless router etc.), and institute State whether the communications band used is the first communications band, i.e. the communications band of 2.4GHz is sentenced if it is the first communications band Determine WiFi module and first communications band is used, if non-first communications band, for example, being the second communications band, then Return re-executes S3401.

Since WiFi module and bluetooth module use the first communications band, then it will lead to bluetooth module and WiFi module be same When using a radio-frequency antenna, and the bandwidth of the first communications band is limited, for example, the bandwidth of the first communications band is 2.4GHz to 2.48GHz, WiFi are to select one in 12 overlapped channels in 22MHz bandwidth, and bluetooth is then in frequency range Frequency hopping between 79 1MHz channels of equispaced.Therefore, no matter which channel WiFi is using, and all exists between the two mutually relevant It disturbs.Then WiFi will affect the transmission of bluetooth, so that bandwidth corresponding to bluetooth can not obtain highest transmission value, therefore, it is necessary to will The bandwidth of bluetooth improves, thus improve electronic equipment pass through exported between bluetooth and wireless audio playback equipment the rate of transmission with And the data volume upper limit that can be transmitted every time.

That is, judging that the WiFi module when using first communications band, executes S3402: according to pre- If bandwidth and encoding rate corresponding relationship, improve target data between the electronic equipment and the wireless audio playback equipment The bandwidth of link.

Specifically, the mode of 2.4GHz frequency range can be shared according to WiFi module and bluetooth module and improve electronic equipment with The bandwidth of destination data link between the wireless audio playback equipment.For example, the mode for sharing 2.4GHz frequency range includes WiFi Module and bluetooth module time division multiplexing, can also be that WiFi module and bluetooth module respectively use certain frequency range.

As an implementation, WiFi module and bluetooth module time division multiplexing.Assuming that the corresponding data-link of WiFi module Road is WiFi link, and between electronic equipment and wireless audio playback equipment is destination data link, then in electronic equipment When WiFi module and bluetooth module use 2.4GHz frequency range simultaneously, electronic equipment is that destination data link and WiFi link distribute not The same time point using 2.4GHz frequency range, so that 2.4GHz frequency range is used alternatingly in destination data link and WiFi link, That is, the antenna of 2.4GHz is used alternatingly in WiFi module and bluetooth module.And the time that bluetooth module is able to use determines The speed between electronic equipment and wireless audio playback equipment by bluetooth data transmission is determined, and and second can not transmit Data volume, i.e. bandwidth.

Then at this point, improving the bandwidth of destination data link between the electronic equipment and the wireless audio playback equipment Embodiment can be, and improves destination data link between electronic equipment and the wireless audio playback equipment and is able to use The time span of the antenna of 2.4GHz, correspondingly, the time span of the antenna of the be able to use 2.4GHz of WiFi link can reduce. For example, before adjustment, in each second, 1/3 time, destination data link uses the antenna of 2.4GHz, and residue 2/3 when Between, WiFi link uses the antenna of 2.4GHz.And after the adjustment, in each second, 2/3 time, destination data link is used The antenna of 2.4GHz, and the time of residue 1/3, WiFi link use the antenna of 2.4GHz, then destination data link energy each second Enough transmission times increase, and the data volume that can be transmitted just will increase, i.e., bandwidth improves.

As another embodiment, WiFi module and bluetooth module respectively use a part frequency of the first communications band Section, specifically, frequency range used in WiFi module is different from frequency range used in the bluetooth module, in some embodiments, Frequency range non-overlapping used in frequency range used in WiFi module and the bluetooth module.As shown in fig. 6, it is logical to show first Believe in frequency range, the schematic diagram of frequency range used in frequency range used in WiFi module and the bluetooth module, wherein assuming that WiFi Frequency range used in module is named as WiFi frequency range, and frequency range, that is, destination data link is described first used in bluetooth module Frequency range in communications band is named as Bluetooth band.As shown in Figure 6, wherein region represented by p1 is the bandwidth of Bluetooth band, And region represented by p2 is the bandwidth of WiFi frequency range.Then p1 and p2 is independent two regions, and there is no interference from each other. Then shown in Fig. 6, Bluetooth band and WiFi frequency range are continuous regions, and as another embodiment, it can also not It is that continuous region is constituted, as shown in Figure 7, wherein it is the bandwidth of WiFi frequency range represented by hatched example areas, and other regions are The bandwidth of Bluetooth band.

Specifically, the bandwidth of Bluetooth band not necessarily have to be than WiFi frequency range with roomy, as long as needing in electronic equipment When by the encryption algorithm of high code-rate by wireless audio playback equipment is sent to after audio data coding, Bluetooth band Bandwidth can be sufficiently large, and the transmission speed for meeting the audio data after the audio coding algorithms coding by the encoding rate meets It needing, i.e. Fig. 6 and 7 is only one embodiment, rather than between the bandwidth to this Bluetooth band and the bandwidth of WiFi frequency range Size relation restriction.

In some embodiments, electronic equipment is when using WiFi module, in order to guarantee the number transmitted using WiFi According to speed it is only slow, need to guarantee WiFi bandwidth meet a minimum.Therefore, according to preset bandwidth and encoding rate Corresponding relationship improves the specific reality of the bandwidth of destination data link between the electronic equipment and the wireless audio playback equipment Apply mode are as follows: the lowest-bandwidth demand that the WiFi module uses first communications band is obtained, according to the WiFi module Lowest-bandwidth demand and the encoding rate, improve target data between the electronic equipment and the wireless audio playback equipment Bandwidth of the link in first communications band.

Wherein, the lowest-bandwidth demand of WiFi module can be user according to demand and set, for example, it is certain downloading it is soft Part can set the upper limit value and lower limit value of a downloading when downloading, and the lower limit value can serve as WiFi module Lowest-bandwidth demand.Furthermore it is also possible to be set according to the data content of the required downloading of user, for example, being listened in user When audio, the sound quality for the audio that user is chosen is different, and corresponding data volume is also different, then obtains the data volume of audio And the play time of the audio, so as to obtain downloading data amount each second, thus when avoiding user from listening to music, The case where audio data after currently playing node buffers downloading not in time and pause is caused to play.Therefore, can according to It the data volume of the data of downloading and plays time span required for the data and sets, for example, the data of 10M, when broadcasting Between be 10 seconds, in order to avoid Caton bandwidth need be greater than or equal to 1M/S, i.e., the lowest-bandwidth demand of WiFi module be 1M/S.

Then, further according to the lowest-bandwidth demand of the WiFi module and the encoding rate, improve the electronic equipment with Bandwidth of the destination data link in first communications band between the wireless audio playback equipment, that is to say, that mentioning Band of the destination data link in first communications band between the high electronic equipment and the wireless audio playback equipment When wide, need to guarantee that bandwidth of the WiFi module in first communications band is needed not less than the lowest-bandwidth of WiFi module It asks.

Specifically, the first frequency sub-band region in first communications band is allocated to the WiFi module, wherein institute The bandwidth for stating the first frequency sub-band region is matched with the lowest-bandwidth demand of the WiFi module.As shown in fig. 6, wherein corresponding to p2 The bandwidth in region matched with the lowest-bandwidth demand of WiFi module, then the p2 it is corresponding be exactly in the first communications band first Frequency sub-band region.For example, the lowest-bandwidth of WiFi module is aMbps, then the first frequency sub-band region in the first communications band Bandwidth is also aMbps, to ensure that the lowest-bandwidth demand of WiFi module.

Illustratively, it is assumed that the total bandwidth of the first communications band is 100Mbps, the current band of WiFi module and bluetooth module Width is 50Mbps, and the lowest-bandwidth demand of WiFi module is 20Mbps, then modifies the bandwidth of WiFi module from 50Mbps For 20Mbps, then the current bandwidth of bluetooth module can be revised as 80Mbps, so that the bandwidth of bluetooth module be improved.When So, the bandwidth of bluetooth module can also be increased to XMbps, wherein the numerical value of X is greater than 50 and less than 80, for example, by bluetooth mould The bandwidth of block is increased to 70Mbps, can not only improve the bandwidth of bluetooth module as a result, can also avoid the band of bluetooth module It is wider than high and causes the power consumption of electronic equipment excessive, furthermore it is also possible to a part of protection bandwidth is reserved to WiFi module, in WiFi When demand of the module to bandwidth improves, it can suitably increase the bandwidth of WiFi module, while not influencing the bandwidth of bluetooth module again.

Then, it is the second son frequency that the ghz area except first frequency sub-band region is removed in first communications band Then bandwidth of the destination data link in the second frequency sub-band region is improved further according to the encoding rate in section region.Also It is to say, in the first communications band, the region of bandwidth identical with the lowest-bandwidth of WiFi module is allocated to WiFi module, so It afterwards, is that bluetooth module distributes frequency band according to encoding rate, so as to protect then out of remaining region, i.e. the second frequency sub-band region Card centainly ensure that WiFi module normal use bandwidth when improving bandwidth for bluetooth module, and avoid no limitation Raising bluetooth module bandwidth and cause WiFi module can not normal use.

It, by this way can be by the bandwidth of WiFi module then if the bandwidth of WiFi module before adjustment is bigger Minimum requirements are reduced to, and increase the bandwidth of bluetooth simultaneously.

S305: by the destination data link after raising bandwidth, the audio data is sent to the wireless audio and is broadcast Put equipment.

Therefore, when WiFi module and bluetooth module are used in conjunction with the antenna of 2.4GHz, since WiF module is also using The communications band of 2.4GHz then will limit the bandwidth that bluetooth module is able to use, and can reduce bluetooth module and is able to use Bandwidth then reduces the bandwidth of WiFi module, so that the upper limit value for the bandwidth that bluetooth can be improved increases, that is, can be more The big bandwidth for improving bluetooth module.
