Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

The in-vehicle apparatus (HF side) and the mobile terminal (AG side) are each equipped with an audio device such as a microphone, a speaker, and the like. In the existing bluetooth phone (HFP) protocol, when a voice call occurs (including an incoming call or a local outgoing call), an audio device at the HF end is generally used for bluetooth call, that is, for collecting and playing audio data; or the audio equipment of the AG end is used for collecting and playing the audio data of the voice call. That is, there is a binding relationship between the input and output of the audio data for the bluetooth call.

For example, fig. 1 shows a situation that when a voice call occurs based on an existing bluetooth telephone protocol, a bluetooth call is established between an HF terminal and an AG terminal, and audio data of the bluetooth call is collected and played by using an audio device of the HF terminal. The microphone 111 of the in-vehicle device 11 is responsible for collecting audio data, and the speaker 112 is responsible for playing the audio data. The bluetooth module 113 of the in-vehicle device 11 and the bluetooth module 121 of the mobile terminal 12 are used for mutual transmission of audio data, and the radio frequency circuit 122 of the mobile terminal 12 and the radio frequency circuit 131 of the peer device 13 are used for mutual transmission of audio data. The mobile terminal 12 and the opposite terminal device 13 are an initiator and a receiver of a voice call, and the mobile terminal 12 acquires and plays audio data by means of the vehicle-mounted device 11.

Based on the existing Bluetooth telephone protocol, when a microphone at the HF end is damaged or is not equipped with a microphone and a loudspeaker at the HF end works normally, when a voice call occurs, audio data is collected and played by default by using audio equipment at the HF end, which leads to the situation that the audio data cannot be collected, the audio data can only be collected and played by switching to using audio equipment at the AG end, and the loudspeaker at the HF end can not participate in the Bluetooth call although working normally.

In view of the above, an embodiment of the present invention provides a method for controlling a bluetooth device, which is used to solve the above technical problem.

Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a control method of a bluetooth device according to the present application. It should be noted that the control method of the bluetooth apparatus described in this embodiment is not limited to the following steps:

s101: establishing a Bluetooth communication connection between a first Bluetooth device and a second Bluetooth device;

in this embodiment, a bluetooth communication connection is established between a first bluetooth device and a second bluetooth device. When the Bluetooth call occurs, the audio data of the Bluetooth call can be transmitted between the first Bluetooth device and the second Bluetooth device.

S102: acquiring setting parameters from a second Bluetooth device;

in this embodiment, the first bluetooth device acquires the setting parameters from the second bluetooth device. The setting parameter is used for indicating the operation state of the audio control circuit of the first Bluetooth device on the audio input device and/or the audio output device of the first Bluetooth device.

S103: setting the operation state of an audio control circuit of the first Bluetooth device on an audio input device and/or an audio output device of the first Bluetooth device according to the setting parameters;

in this embodiment, after the setting parameters are acquired from the second bluetooth device, the operating state of the audio control circuit of the first bluetooth device on the audio input device and/or the audio output device of the first bluetooth device is set according to the setting parameters. The audio control circuit comprising the first Bluetooth device is set to collect audio data only through the audio input equipment of the first Bluetooth device and participate in Bluetooth communication; or the audio data is played only through the audio output equipment of the first Bluetooth device to participate in the Bluetooth communication; or the audio input device and the audio output device of the first Bluetooth device participate in the Bluetooth communication at the same time.

Therefore, in the control method of the bluetooth device provided by the present application, there is no binding relationship between the audio data input terminal (audio input device) and the audio output terminal (audio output device) of the first bluetooth device for participating in the bluetooth call, and the two are not necessarily participating in the bluetooth call at the same time, that is, the control method of the bluetooth device provided by the present application removes the binding relationship between the audio data input terminal and the audio output terminal of the bluetooth call.

Referring to fig. 3, fig. 3 is a flowchart illustrating a control method of a bluetooth device according to a second embodiment of the present application. It should be noted that the control method of the bluetooth apparatus described in this embodiment is not limited to the following steps:

s201: establishing a Bluetooth communication connection between a first Bluetooth device and a second Bluetooth device;

in the present embodiment, the bluetooth call is based on HFP (bluetooth telephony) protocol. One of the first bluetooth device and the second bluetooth device is in voice communication, and can establish bluetooth communication with the other party so as to realize input and output of audio data for voice communication by means of the other party. In order to implement the audio data interchange based on the HFP (bluetooth telephony) protocol between the first bluetooth device and the second bluetooth device, a bluetooth communication connection needs to be established between the first bluetooth device and the second bluetooth device, and the established bluetooth communication connection is based on the existing bluetooth protocol, which is within the understanding scope of those skilled in the art and will not be described herein again.

Further, after the bluetooth communication connection is established between the first bluetooth apparatus and the second bluetooth apparatus, and before the first bluetooth apparatus acquires the setting parameters from the second bluetooth apparatus, acquiring a configuration file for characterizing whether an audio input device and/or an audio output device of the first bluetooth apparatus is in an available state or a state parameter generated by the configuration file; and sending the configuration file or the state parameter to the second Bluetooth device, so that the second Bluetooth device can know whether the audio input device and/or the audio output device of the first Bluetooth device are in an available state, and meanwhile, the configuration file or the state parameter is used as a reference for generating a setting parameter to control whether the audio input device and/or the audio output device of the first Bluetooth device normally work (including acquiring audio data, outputting audio data and the like).

Optionally, the first bluetooth device is a vehicle-mounted device, and the second bluetooth device is a mobile terminal; or the first Bluetooth device is a mobile terminal, and the second Bluetooth device is a vehicle-mounted device. Wherein the first bluetooth device is described as a controlled party of the control method of the bluetooth device of the present application, and the second bluetooth device is described as a controlled party of the control method of the bluetooth device of the present application.

The vehicle-mounted device is a set of devices which take an Electronic Control Unit (ECU) as a core and are integrated on an automobile or the like, so as to meet the requirements of a user in the driving process.

S202: acquiring a link connection request or a link connection response for establishing a voice communication link from a second Bluetooth device;

in this embodiment, after the bluetooth communication connection is established between the first bluetooth device and the second bluetooth device, the bluetooth communication can be established between the first bluetooth device and the second bluetooth device when one of the two devices has a voice call, so as to transmit audio data for the voice call to each other, which requires that a voice communication link (e.g., ESCO/SCO link, etc.) needs to be established between the first bluetooth device and the second bluetooth device. The method specifically comprises the following steps: the first bluetooth device acquires a link connection request or a link connection response for establishing a voice communication link from the second bluetooth device. The voice communication link takes Bluetooth communication connection as a carrier, and a link connection request or a link connection response is transmitted through the Bluetooth communication connection.

The first bluetooth device can be an initiator or a receiver of a bluetooth call, and the second bluetooth device is corresponding to the first bluetooth device and is the receiver or the initiator. Specifically, when a first bluetooth device actively initiates a bluetooth call, the first bluetooth device sends a link connection request for establishing a voice communication link to a second bluetooth device, and completes establishment of the voice communication link after the first bluetooth device acquires a corresponding link connection response from the second bluetooth device; and when the first Bluetooth device passively receives the Bluetooth call, the first Bluetooth device acquires a link connection request for establishing a voice communication link from the second Bluetooth device and feeds back a corresponding link connection response to complete the establishment of the voice communication link.

For example, when the first bluetooth device is a vehicle-mounted device and the second bluetooth device is a mobile terminal, the condition that the first bluetooth device actively initiates a bluetooth call is to call out a voice call through the first bluetooth device, which requires that the first bluetooth device actively initiates a bluetooth call with the second bluetooth device, and establishes a voice call with a called party by means of the second bluetooth device; the situation that the first bluetooth device passively receives the bluetooth call is that the second bluetooth device calls out the voice call, the second bluetooth device needs to actively initiate the bluetooth call with the first bluetooth device (namely, the first bluetooth device passively receives the bluetooth call), and audio data for the voice call is collected and played by means of the first bluetooth device.

The following describes an improvement of the present embodiment to the existing protocol, taking the first bluetooth device as an in-vehicle device, and an audio input device (which is usually a microphone, etc.) thereof as an example:

for the existing bluetooth telephony protocol, the function prototype of the link connection request for the voice communication link is: ConnectAudioNative (byte [ ] address), the parameter address is the Bluetooth MAC address of the opposite end. An enable function defining an operating state of an audio control circuit of the first bluetooth device, which function is prototyped as audiomanager.setparameters ("hfp _ enable ═ true"), is used to set the operating state of the audio control circuit of the first bluetooth device to an audio input device of the first bluetooth device. The parameter hfp _ enable ═ true indicates that the audio control circuit is enabled, and accordingly the operating state of the audio control circuit to the audio input device is: the audio control circuit is configured to collect audio data via an audio input device of the first bluetooth apparatus. And after calling the discrete Audio native function, the voice communication link is disconnected.

The embodiment improves the existing bluetooth telephone protocol by: a concept is proposed for setting parameters for indicating an operational state of an audio control circuit of a first bluetooth arrangement to an audio input device and/or an audio output device of the first bluetooth arrangement.

Setting parameters are added to the function of the link connection request, and the new function format is connected audio native (byte [ ] address, Boolean state), where the Boolean state is the setting parameters (corresponding to the audio input device of the first bluetooth device). And Boolean carmistate describes that the value of the setting parameter is "true" or "false". It is understood that the setting parameters can also be added to the function of the corresponding link connection response.

Set parameters are added to an enable function defining the operating state of the audio control circuit of the first bluetooth device, and the new function format is audiomanager.

Therefore, the link connection request or the link connection response for establishing the voice communication link acquired by the first bluetooth device from the second bluetooth device of the present embodiment includes a setting parameter for indicating the operation state of the audio control circuit of the first bluetooth device.

It is to be understood that the above setting parameters are for the audio input device of the first bluetooth apparatus. The parameters for the audio output device of the first bluetooth apparatus may also be added to the setting parameters. The setting parameters include parameters of audio input equipment and audio output equipment of the first Bluetooth device, and the audio control circuit of the first Bluetooth device is indicated to the operating state of the audio input equipment and the audio output equipment of the first Bluetooth device according to the values of the corresponding parameters.

S203: extracting a setting parameter from the link connection request or the link connection response;

in this embodiment, when the first bluetooth device is an active initiator of a bluetooth call, the first bluetooth device extracts a setting parameter from a link connection response fed back by the second bluetooth device; and when the first Bluetooth device is a passive receiver of the Bluetooth call, the first Bluetooth device extracts the setting parameters from the link connection request sent by the second Bluetooth device.

S204: setting the operation state of an audio control circuit of the first Bluetooth device on an audio input device and/or an audio output device of the first Bluetooth device according to the setting parameters;

in this embodiment, after the first bluetooth device extracts the setting parameter, the operating state of the audio control circuit of the first bluetooth device to the audio input device and/or the audio output device of the first bluetooth device is set according to the setting parameter, which may specifically include whether the audio control circuit of the first bluetooth device collects audio data through the audio input device and/or whether audio data is played through the audio output device, so as to participate in the bluetooth call between the first bluetooth device and the second bluetooth device.

In other words, setting the operating state of the audio control circuit of the first bluetooth apparatus to the audio input device and/or the audio output device of the first bluetooth apparatus at least includes: the audio control circuit of the first bluetooth device is configured to play audio data through the audio output device of the first bluetooth device, but not to collect audio data through the audio input device of the first bluetooth device; or the audio control circuit of the first bluetooth device is configured to collect audio data through the audio input device of the first bluetooth device, but not play the audio data through the audio output device of the first bluetooth device. When the audio input device or the audio output device of the first Bluetooth device is damaged, the audio control circuit of the first Bluetooth device does not participate in the Bluetooth communication through the damaged audio device, and the undamaged audio device can participate in the Bluetooth communication, so that a fault-tolerant processing scheme is provided for the first Bluetooth device; even under the condition that the first Bluetooth device is not provided with an audio input device or an audio output device, the audio control circuit of the first Bluetooth device does not participate in Bluetooth communication through the audio device which is not provided, the provided audio device can participate in Bluetooth communication, the first Bluetooth device can normally participate in Bluetooth communication with the second Bluetooth device, the number of audio devices which are provided for the first Bluetooth device can be reduced, and the cost of the first Bluetooth device is reduced.

Of course, setting the operating state of the audio control circuit of the first bluetooth apparatus to the audio input device and/or the audio output device of the first bluetooth apparatus may also include such things as: the audio control circuit of the first bluetooth device is configured to play audio data through the audio output device of the first bluetooth device and to collect audio data through the audio input device of the first bluetooth device; or the audio control circuit of the first bluetooth device is set not to collect audio data through the audio input device of the first bluetooth device and also not to play audio data through the audio output device of the first bluetooth device. And are not limited herein.

In addition, in combination with the improved protocol, the parameter values corresponding to the audio input device and the audio output device in the set parameters determine the operation states of the audio control circuit on the audio input device and the audio output device of the first bluetooth apparatus. For example, when the parameter values corresponding to the audio input device and the audio output device in the set parameters are all "true", the audio control circuit of the first bluetooth device is configured to play audio data through the audio output device of the first bluetooth device, and acquire the audio data through the audio input device of the first bluetooth device; and when the parameter value corresponding to the audio input device in the set parameters is "true" and the parameter value corresponding to the audio output device is "false", the audio control circuit of the first bluetooth device is configured to collect audio data through the audio input device of the first bluetooth device, but not play the audio data through the audio output device of the first bluetooth device.

Further, after the voice communication link is successfully established, the upper module of the first bluetooth device may receive a message of the headsettclienthalconstantans, audio _ STATE _ CONNECTED, and receive the setting parameter (from the link connection request or the link connection response) carried by the message. The setting parameters are then loaded into the enabling function of the audio control circuit of the first bluetooth device, the functional format of which has been set forth in detail above. And setting the operation state of the audio control circuit of the first Bluetooth device on the audio input device and/or the audio output device of the first Bluetooth device according to the enabling function of the audio control circuit of the first Bluetooth device.

Referring to fig. 4, fig. 4 is a flowchart illustrating a control method of a bluetooth device according to a third embodiment of the present application. It should be noted that the control method of the bluetooth apparatus described in this embodiment is not limited to the following steps:

s301: establishing a Bluetooth communication connection between a first Bluetooth device and a second Bluetooth device;

S302: generating a setting parameter;

in the present embodiment, the second bluetooth device generates the setting parameters. The setting parameter is used for indicating the operation state of the audio control circuit of the first Bluetooth device on the audio input device and/or the audio output device of the first Bluetooth device.

S303: sending the setting parameters to the first Bluetooth device;

in this embodiment, the second bluetooth device transmits the setting parameters to the first bluetooth device. And after the first Bluetooth device acquires the setting parameters, setting the operation state of the audio control circuit of the first Bluetooth device on the audio input equipment and/or the audio output equipment of the first Bluetooth device according to the setting parameters. The audio control circuit comprising the first Bluetooth device is set to collect audio data only through the audio input equipment of the first Bluetooth device and participate in Bluetooth communication; or the audio data is played only through the audio output equipment of the first Bluetooth device to participate in the Bluetooth communication; or the audio input device and the audio output device of the first Bluetooth device participate in the Bluetooth communication at the same time.

Referring to fig. 5, fig. 5 is a flowchart illustrating a fourth embodiment of a bluetooth device control method according to the present application. It should be noted that the control method of the bluetooth apparatus described in this embodiment is not limited to the following steps:

s401: establishing a Bluetooth communication connection between a first Bluetooth device and a second Bluetooth device;

in this embodiment, one of the first bluetooth device and the second bluetooth device performs a voice call, and may establish a bluetooth call with the other to implement input and output of audio data for the voice call by the other. In order to realize audio data transmission between a first bluetooth device and a second bluetooth device based on an HFP (bluetooth telephony) protocol, a bluetooth communication connection needs to be established between the first bluetooth device and the second bluetooth device, and the established bluetooth communication connection is based on an existing bluetooth protocol.

S402: generating a setting parameter;

In this embodiment, before generating the setting parameter, a configuration file for characterizing whether the audio input device and/or the audio output device of the first bluetooth apparatus is in an available state or a state parameter generated by the configuration file may be obtained. The profile or status parameter serves as a reference for the second bluetooth device to generate the setting parameters.

When the audio input device and/or the audio output device of the first Bluetooth device is in an available state, the second Bluetooth device can generate a setting parameter indicating that the audio control circuit of the first Bluetooth device participates in the Bluetooth call through or not through the audio input device and/or the audio output device of the first Bluetooth device. And when the audio input device and/or the audio output device of the first Bluetooth device is in an unavailable state, the second Bluetooth device only generates a setting parameter indicating that the audio control circuit of the first Bluetooth device does not participate in the Bluetooth call through the audio input device and/or the audio output device of the first Bluetooth device. Therefore, when the audio input device and/or the audio output device of the first Bluetooth device are in an unavailable state, the second Bluetooth device still generates the setting parameters indicating that the audio control circuit of the first Bluetooth device participates in the Bluetooth call through the audio input device and/or the audio output device of the first Bluetooth device, and adverse effects are caused on the Bluetooth call between the first Bluetooth device and the second Bluetooth device.

The configuration file is a file stored in a fixed directory of the first bluetooth device system, and variables in the configuration file are used for representing whether the audio input device and/or the audio output device of the first bluetooth device are in an available state. When the first Bluetooth device is enabled, the configuration file is read to obtain information whether the audio input device and/or the audio output device of the first Bluetooth device are/is in an available state.

After the first Bluetooth device reads the configuration file, the configuration file can be automatically analyzed, the state parameters are generated according to the configuration file, and whether the audio input equipment and/or the audio output equipment of the first Bluetooth device are in an available state or not is judged by the first Bluetooth device. The state parameters generated by the configuration file are then sent to the second bluetooth device via the bluetooth communication connection, informing the second bluetooth device whether its audio input device and/or audio output device is in an available state. Or after the first Bluetooth device reads the configuration file, the configuration file is directly sent to the second Bluetooth device, and the second Bluetooth device judges whether the audio input equipment and/or the audio output equipment of the first Bluetooth device are/is in an available state according to the configuration file.

The following uses the audio input device of the first bluetooth apparatus as an example to roughly describe the usage flow of the configuration file:

the first bluetooth device stores a profile under a fixed directory, for example named microstatus. When the variable microphonestatus in the configuration file is equal to true, the audio input equipment of the first Bluetooth device is represented to be in an available state; and when the variable microphonestatus in the configuration file is equal to false, the audio input device representing the first bluetooth apparatus is not in an available state, i.e., is not available.

The configuration file is configured in the following two ways:

one way is that the first bluetooth device completes the variable configuration of the configuration file when the system is burned. If the variable microphonestatus in the configuration file is equal to true, it indicates that the first bluetooth device is equipped with the audio input device, and if the variable microphonestatus in the configuration file is equal to false, it indicates that the first bluetooth device is not equipped with the audio input device.

The other mode is that the user modifies the variable configuration values of the configuration file by setting on a system setting interface of the first Bluetooth device. The method can identify the situation that the audio input equipment of the first Bluetooth device is unavailable by utilizing the configuration file in a user modification mode when the audio input equipment of the first Bluetooth device is damaged.

It is understood that, for the audio output device of the first bluetooth apparatus, a configuration file indicating whether the audio output device of the first bluetooth apparatus is in a usable state may be additionally added to the system of the first bluetooth apparatus, and the naming of the configuration file and its variables may be distinguished from the naming of the audio input device.

Referring to fig. 6, fig. 6 shows the interaction of the configuration file between the first bluetooth device 21 and the second bluetooth device 22. After the first bluetooth device 21 establishes a bluetooth communication connection with the second bluetooth device 22, the first bluetooth device 21 may send a configuration file or status parameters to the second bluetooth device 22 to notify the second bluetooth device 22 whether the audio input device and/or the audio output device of the first bluetooth device 21 are in an available state. For example, in fig. 6, after the first bluetooth device 21 autonomously analyzes the configuration file, a custom bluetooth command (AT + CARMIC ═ 0) is generated according to the configuration file, and includes a status parameter (AT + CARMIC), the custom bluetooth command describes that the audio input device of the first bluetooth device 21 is in an unavailable state, and the second bluetooth device 22 feeds back a response confirmed by the first bluetooth device 21 after receiving the custom bluetooth command.

Therefore, the reference of the configuration file or the status parameter as the second bluetooth device generation setting parameter may specifically be: when the value of the state parameter (AT + CARMIC) is 1, that is, AT + CARMIC is 1, the value of the setting parameter may be true or false, and the second bluetooth device may generate a setting parameter indicating that the audio control circuit of the first bluetooth device participates in the bluetooth call with or without the audio input device of the first bluetooth device; and when the value of the state parameter (AT + CARMIC) is 0, that is, AT + CARMIC is 0, the value of the setting parameter can only be false, and the second bluetooth device generates the setting parameter indicating that the audio control circuit of the first bluetooth device does not participate in the bluetooth call through the audio input device of the first bluetooth device.

S403: transmitting a link connection request or a link connection response for establishing a voice communication link to the first bluetooth device;

in this embodiment, when the second bluetooth device is an active initiator of a bluetooth call, the second bluetooth device loads setting parameters in a link connection request for establishing a voice communication link and sends the link connection request to the first bluetooth device, and after receiving the link connection request, the first bluetooth device may extract the setting parameters from the link connection request. And when the second Bluetooth device is a passive receiver of the Bluetooth call, the second Bluetooth device loads the setting parameters in the link connection response for establishing the voice communication link and sends the link connection response to the first Bluetooth device, and the setting parameters can be extracted from the link connection response after the first Bluetooth device receives the link connection response. The enabling process of setting parameters for the audio input device and/or the audio output device of the first bluetooth apparatus has been described in detail in the above embodiments, and will not be described herein again.

S404: setting the operation state of the audio control circuit of the second Bluetooth device on the audio input equipment and/or the audio output equipment of the second Bluetooth device according to the setting parameters;

in this embodiment, after the second bluetooth device indicates the operation state of the audio control circuit of the first bluetooth device according to the setting parameter, the second bluetooth device also needs to set the operation state of the audio control circuit of the second bluetooth device to the audio input device and/or the audio output device of the second bluetooth device according to the setting parameter.

The operation state of the audio control circuit of the second Bluetooth device to the audio input device and/or the audio output device of the second Bluetooth device is opposite to the operation state of the audio control circuit of the first Bluetooth device to the audio input device and/or the audio output device of the first Bluetooth device.

In other words, the setting parameter indicates that the audio control circuit of the first Bluetooth device is not passing the audio control circuit of the first Bluetooth device in the operating state of the audio input apparatus of the first Bluetooth device

The audio input device of the first bluetooth apparatus collects audio data to participate in the bluetooth call. Correspondingly, the audio control circuit of the second bluetooth device needs to acquire audio data for the audio control circuit of the second bluetooth device through the audio input device of the second bluetooth device to participate in the bluetooth call, so as to ensure the normal operation of the bluetooth call.

The second bluetooth apparatus may also include a configuration file for representing whether the audio input device and/or the audio output device of the second bluetooth apparatus are in the available state, and may also generate a corresponding state parameter according to the configuration file to mark whether the audio input device and/or the audio output device of the second bluetooth apparatus are in the available state, and also serve as a reference for generating the setting parameter.

It should be noted that, the second bluetooth apparatus reasonably generates the setting parameters by using the configuration file or the state parameters generated by the configuration file as a reference for generating the setting parameters, so as to enable the second bluetooth apparatus and the audio input device and/or the audio output device of the first bluetooth apparatus to ensure the normal operation of the bluetooth call. The second bluetooth device may also provide a human-computer interaction window, the states of the audio input devices and/or the audio output devices of the first bluetooth device and the second bluetooth device (whether the audio input devices and/or the audio output devices are available or not may be obtained according to the corresponding configuration files or the state parameters) are displayed to the user through the human-computer interaction window, and the user generates corresponding setting parameters according to the states of the audio input devices and/or the audio output devices of the first bluetooth device and the second bluetooth device displayed by the human-computer interaction window and reasonably selects the operating states of the audio input devices and/or the audio output devices of the first bluetooth device and the second bluetooth device through the human-computer interaction window. For example, when the audio input device of the first bluetooth device is unavailable, the user learns and operates to generate the corresponding setting parameters from the man-machine interaction window, so that the user does not participate in the bluetooth call through the audio input device of the first bluetooth device but participates in the bluetooth call through the audio input device of the second bluetooth device.

Please refer to fig. 7. The following describes the interaction process between the first bluetooth device 31 and the second bluetooth device 32 in the present application, taking the switching of the audio input device and the first bluetooth device 31 as a passive receiver of the bluetooth call as an example:

step 1: a bluetooth communication connection is established between the first bluetooth device 31 and the second bluetooth device 32.

Step 2: when a voice call occurs, the second bluetooth device 32 sends a link connection request to the first bluetooth device 31; wherein, the link connection request is loaded with a setting parameter, and the setting parameter carmistate is true.

And step 3: the first bluetooth device 31 feeds back a link connection response to the second bluetooth device 32, and the first bluetooth device 31 establishes a voice communication link with the second bluetooth device 32.

Wherein, the first bluetooth device 31 sets the operation state of the audio control circuit of the first bluetooth device 31 to the audio input device of the first bluetooth device 31 according to the setting parameter; and the second bluetooth device 32 sets the operation state of the audio control circuit of the second bluetooth device 32 to the audio input apparatus of the second bluetooth device 32 according to the setting parameter. The result is: the audio data is collected through the audio input device of the first bluetooth device 31, and the audio data is transmitted to the second bluetooth device 32 through the voice communication link, and the audio data is transmitted to the opposite end of the voice call through the second bluetooth device 32. While the audio input device of the second bluetooth arrangement 32 does not collect audio data.

Please refer to fig. 8. The following describes the interaction process between the first bluetooth device 41 and the second bluetooth device 42 in the present application, taking the switching of the audio input device and the first bluetooth device 41 as an active initiator of the bluetooth call as an example:

step 1: a bluetooth communication connection is established between the first bluetooth device 41 and the second bluetooth device 42.

Step 2: when a voice call occurs, the first bluetooth device 41 transmits a link connection request to the second bluetooth device 42.

And step 3: the second bluetooth device 42 feeds back a link connection response to the first bluetooth device 41, and the first bluetooth device 41 establishes a voice communication link with the second bluetooth device 42. The link connection response is loaded with a setting parameter, and the setting parameter carmistate is false.

Wherein, the first bluetooth device 41 sets the operation state of the audio control circuit of the first bluetooth device 41 to the audio input device of the first bluetooth device 41 according to the setting parameter; and the second bluetooth device 42 sets the operation state of the audio control circuit of the second bluetooth device 42 to the audio input apparatus of the second bluetooth device 42 according to the setting parameter. The result is: audio data is collected through the audio input device of the second bluetooth device 42, and the second bluetooth device 42 transmits the audio data to the peer device 43 for voice call. While the audio input device of the first bluetooth arrangement 41 does not collect audio data.

Similarly, the switching of the audio output devices of the first bluetooth device and the second bluetooth device is similar to the interactive process of the audio input devices, the audio input devices are replaced by the audio output devices, and the setting parameters are correspondingly modified, and the switching of the audio input devices of the first bluetooth device and the second bluetooth device is independent of the switching process of the audio output devices and does not affect each other.

In summary, the present application provides a method for controlling a bluetooth apparatus, which discloses setting an operation state of an audio control circuit of a first bluetooth apparatus on an audio input device and/or an audio output device of the first bluetooth apparatus according to a setting parameter. The audio data input end (audio input device) and the output end (audio output device) of the first bluetooth device for bluetooth communication do not necessarily participate in the bluetooth communication at the same time, and a binding relationship does not exist between the audio data input end and the audio data output end, namely the control method of the bluetooth device provided by the application removes the binding relationship between the audio data input end and the audio data output end of the bluetooth communication.
