In a specific embodiment, the connection method of the device is applied to the connection apparatus 400 of the device as shown in fig. 13 and the first electronic device 100 (fig. 15) configured with the connection apparatus 400.

As will be described in detail below with respect to the flow shown in fig. 3, the method for connecting the device may specifically include the following steps:

step S110: and under the condition that the first electronic equipment plays the first target audio data, acquiring first playing capability information of the Bluetooth equipment, wherein the first playing capability information is used for indicating the audio type supported to play by the Bluetooth equipment to the first electronic equipment.

In this embodiment, a BLE connection may be established between the first electronic device and the bluetooth device.

As one way, the bluetooth device may be placed in the earphone box, and when detecting that the earphone box is uncapped, a BLE connection between the first electronic device and the bluetooth device may be established. As yet another way, the bluetooth device may be placed in the earphone box, and when it is detected that the bluetooth device is removed from the earphone box, a BLE connection between the first electronic device and the bluetooth device may be established. As yet another way, the bluetooth device may be placed in the earphone box, and when it is detected that the bluetooth device is taken out of the earphone box, whether the bluetooth device is in a wearing state may be detected, and when it is detected that the bluetooth device is in the wearing state, a BLE connection between the first electronic device and the bluetooth device may be established.

In this embodiment, under the condition that the first electronic device and the bluetooth device establish BLE connection, whether the first electronic device plays audio data or not may be detected, where if it is detected that the first electronic device plays first target audio data, first playing capability information of the bluetooth device may be obtained, where the first playing capability information is used to indicate to the first electronic device that the bluetooth device supports audio types that are played.

The audio types supported by the bluetooth device may include a music media type, a call communication type, a game type, and the like, which are not limited herein.

In one manner, if the first electronic device is detected to play the first target audio data, the first electronic device may acquire the private protocol parameter of the bluetooth device, and based on the private protocol parameter, the first electronic device may know the audio type supported by the bluetooth device to play.

As yet another approach, if the first electronic device is detected to play the first target audio data, the first electronic device may obtain an available audio context (Available Audio Contexts) of the bluetooth device, based on which the first electronic device may be aware of the audio types supported by the bluetooth device for play.

In this embodiment, the bluetooth device may transmit a low-power-consumption audio broadcast, and the first electronic device may receive the low-power-consumption audio broadcast transmitted by the bluetooth device, so as to obtain information such as a bluetooth address of the bluetooth device from the low-power-consumption audio broadcast, and then establish a BLE connection with the bluetooth device based on the information such as the bluetooth address of the bluetooth device.

As a way, the bluetooth device may be placed in the earphone box, when detecting that the earphone box is uncapped, the low-power-consumption audio broadcast may be emitted, and when the first electronic device receives the low-power-consumption audio broadcast, the first electronic device may establish a BLE connection with the bluetooth device in response to the low-power-consumption audio broadcast. As yet another approach, the bluetooth device may be placed in a headset box, and when it is detected that the bluetooth device is removed from the headset box, a low power audio broadcast may be transmitted, and when the low power audio broadcast is received by the first electronic device, a BLE connection with the bluetooth device may be established in response to the low power audio broadcast. As still another way, the bluetooth device may be placed in the earphone box, and when it is detected that the bluetooth device is taken out from the earphone box, whether the bluetooth device is in a wearing state may be detected, and when it is detected that the bluetooth device is in the wearing state, a low-power-consumption audio broadcast may be emitted, and when the first electronic device receives the low-power-consumption audio broadcast, a BLE connection with the bluetooth device may be established in response to the low-power-consumption audio broadcast.

In this embodiment, in the case of establishing a BLE connection with a bluetooth device, the first electronic device may read a relevant attribute of the bluetooth device based on the BLE connection, where the relevant attribute may include a state of an available audio context of the bluetooth device and an audio stream endpoint. Correspondingly, under the condition that the first electronic device acquires the state of the available audio context of the Bluetooth device, the state of the available audio context can be saved so as to be used as a reference for whether a connection synchronous stream with the Bluetooth device is established later, so that the rationality of the first electronic device for initiating a synchronous stream connection request is improved, and the power consumption of the first electronic device is reduced.

Step S120: and determining a playing strategy of the first target audio data according to the first playing capability information and the audio type of the first target audio data.

In this embodiment, when determining the first playing capability of the bluetooth device, the first electronic device may determine the playing policy of the first target audio data according to the first playing capability information and the audio type of the first target audio data.

In some embodiments, the first electronic device may obtain an audio type of the first target audio data when playing the first target audio data, and the first electronic device may obtain an audio type supported by the bluetooth device when determining the first playing capability of the bluetooth device. Based on the comparison result, the first electronic device can compare the audio type supported by the bluetooth device to the audio type of the first target audio data, and determine the playing strategy of the first audio data according to the comparison result.

As an implementation manner, if the comparison result indicates that the bluetooth device does not support playing the audio type of the first target audio data, the first target audio data may not be output through the bluetooth device; if the comparison result indicates that the Bluetooth device supports playing the audio type of the first target audio data, the first target audio data can be output through the Bluetooth device.

According to the method for connecting the devices, under the condition that the first electronic device plays the first target audio data, first playing capability information of the Bluetooth device is obtained, the first playing capability information is used for indicating the audio type supported by the Bluetooth device to play to the first electronic device, and according to the first playing capability information and the audio type of the first target audio data, a playing strategy of the first target audio data is determined, so that the playing capability information of the Bluetooth device is obtained through establishing low-power Bluetooth connection with the Bluetooth device, and according to the playing capability information and the audio type of the audio data played by the Bluetooth device, the playing strategy of the audio data which is aimed at the playing is determined, and therefore the audio playing effect and the user experience can be improved.

Referring to fig. 4, fig. 4 is a flow chart illustrating a method for connecting devices according to an embodiment of the present application. The method is applied to the first electronic device, and will be described in detail with respect to the flow shown in fig. 4, where the method for connecting devices specifically includes the following steps:

step S210: and under the condition that the first electronic equipment plays the first target audio data, acquiring first playing capability information of the Bluetooth equipment, wherein the first playing capability information is used for indicating the audio type supported to play by the Bluetooth equipment to the first electronic equipment.

The specific description of step S210 is referred to step S110, and will not be repeated here.

Step S220: and if the first playing capability information indicates that the Bluetooth device supports playing the audio type of the first target audio data, the first target audio data is sent to the Bluetooth device.

In this embodiment, if it is determined that the first playback capability information indicates that the bluetooth device supports playback of the audio type of the first target audio data, the first target audio data may be sent to the bluetooth device to output the first target audio data through the bluetooth device. For example, assuming that the audio type of the first target audio data is "music type" and the first playback capability information indicates that the bluetooth device supports "music type", the first target audio data may be transmitted to the bluetooth device.

In some embodiments, determining that the first playback capability information indicates that the bluetooth device supports playback of the audio type of the first target audio data may establish a connection synchronization stream between the first electronic device and the bluetooth device to send the first target audio data to the bluetooth device over the connection synchronization stream. The connection synchronization stream may include CIS, BIS, etc., and is not limited herein.

As an implementation manner, if it is determined that the first playback capability information indicates that the bluetooth device supports playback of the audio type of the first target audio data, the first electronic device may initiate a synchronous stream connection request to the bluetooth device, and the bluetooth device may establish a connection synchronous stream with the first electronic device in response to the synchronous stream connection request. In the case where it is determined that a connection synchronization stream between the bluetooth device and the first electronic device has been established, then the first target audio data of the first electronic device may be transmitted to the bluetooth device based on the connection synchronization stream to output the first target audio data through the bluetooth device.

Step S230: and if the first playing capability information indicates that the Bluetooth equipment does not support playing the audio type of the first target audio data, monitoring the change of the first playing capability information of the Bluetooth equipment.

In this embodiment, if it is determined that the first playback capability information indicates that the bluetooth device does not support playing the audio type of the first target audio data, the first target audio data may not be sent to the bluetooth device, and a change of the first playback capability information of the bluetooth device may be monitored. For example, assuming that the audio type of the first target audio data is "music type" and the first playback capability information indicates that the bluetooth device does not support "music type", the first target audio data may not be transmitted to the bluetooth device and a change in the first playback capability information of the bluetooth device is monitored.

As one way, if it is determined that the first playback capability information indicates that the bluetooth device does not support playing the audio type of the first target audio data, the first target audio data may be played out, and a change of the first playback capability information of the bluetooth device may be monitored. Wherein the playing out the first target audio data may include: the first target audio data is played through a speaker of the first electronic device.

As yet another way, if it is determined that the first playback capability information indicates that the bluetooth device does not support playback of the audio type of the first target audio data, playback of the first target audio data may be paused, and a change in the first playback capability information of the bluetooth device may be monitored. Wherein pausing the playing of the first target audio data may include: the playing is paused at the current playing of the first target audio data, the playing of the first audio playing data is exited, etc., without limitation.

As still another way, if it is determined that the first playback capability information indicates that the bluetooth device does not support playback of the audio type of the first target audio data, the first target audio data may be sent to other bluetooth devices, where the first electronic device establishes a bluetooth low energy connection with the other bluetooth devices. The first electronic device may establish low-power consumption bluetooth connection with the bluetooth device and other bluetooth devices, respectively, and then, when determining that the first playback capability information indicates that the bluetooth device does not support playing the audio type of the first target audio data, determine whether the other bluetooth device supports playing the audio type of the first target audio data, and if determining that the other bluetooth device supports playing the audio type of the first target audio data, send the first target audio data to the other bluetooth device so as to output the first target audio data through the other bluetooth device.

In some embodiments, the first playback capability information may include an available audio context, and the playback policy of the first target audio data may be determined according to state information of an audio type of the available audio context corresponding to the audio type of the first target audio data.

After the bluetooth device supporting LE Audio establishes BLE connection with the electronic device, the electronic device may obtain an "available Audio context (such as media, conversational, game) of the bluetooth device and an Audio stream endpoint (Audio Stream Endpoint, ASE) supported by the bluetooth device, including Sink ASE and Source ASE, by querying a service (service) and an attribute (attribute) of the bluetooth device, and may configure the corresponding ASE to a corresponding state (i.e., QOS Configured state). When the electronic device and the Bluetooth device have business, a connection synchronous stream is created between the electronic device and the Bluetooth device, and the ASE state is changed into a corresponding state (i.e. Streaming state), and then the audio data can be transmitted in the connection synchronous stream. When the "available audio context" of the bluetooth device is "available" (for example, media in available audio contexts is "YES") and is sent to the currently connected electronic device, the currently connected electronic device may establish a connection synchronization stream with the bluetooth device; when the "available audio context" of the bluetooth device is "unavailable" (e.g., media in available audio contexts is "NO") and is sent to the currently connected electronic device, the electronic device will not establish a connection sync stream with the bluetooth device.

In this embodiment, a BLE connection is established between the first electronic device and the bluetooth device, and the first electronic device may obtain relevant information of the bluetooth device from the bluetooth device based on the BLE connection, for example, the first electronic device may obtain ASE conditions supported by the bluetooth device from the bluetooth device based on the BLE connection, status information of audio types in an available audio context of the bluetooth device, and so on.

In some implementations, the available audio context of the bluetooth device may include a plurality of audio types therein, wherein the plurality of audio types may include a first audio type, a second audio type, a third audio type … …, and an nth audio type. The state information of the audio type in the available audio context of the bluetooth device may include state information of each audio type in the available audio context of the bluetooth device, for example, state information of a first audio type, state information of a second audio type, state information of a third audio type … …, and state information of an nth audio type. In this embodiment, the state information of the audio type in the available audio context is used to indicate whether the audio type in the available audio context is available, i.e., the state information of the audio type in the available audio context is "available/YES", the state information indicating the audio type in the available audio context is an available state, the state information indicating the audio type in the available audio context is "unavailable/NO", and the state information indicating the audio type in the available audio context is an unavailable state.

In some implementations, the first electronic device, upon determining the audio type of the first target audio data, can then detect state information for the audio type corresponding to the audio type of the first target audio data in an available audio context of the bluetooth device. If the state information of the audio type corresponding to the audio type of the first target audio data in the available audio context of the bluetooth device is detected to be in an unavailable state, the audio type of the first target audio data can be determined, the bluetooth device cannot provide the output of the audio data for the first electronic device, and the first electronic device can play the first target audio data outwards, pause playing or play the first target audio data through other bluetooth devices.

For example, assuming that the audio type of the first target audio data is media, state information of media in an available audio context of the bluetooth device may be detected. If the state information of media in the available audio context of the bluetooth device is detected to be NO, it may be determined that the bluetooth device cannot provide the first electronic device with output of the first target audio data for the media, and the first electronic device may process the first target audio data in a manner of playing out, pausing playing, playing through other bluetooth devices, and the like.

In some embodiments, the state change of the available audio context of the bluetooth device may be monitored while the first target audio data is being played, paused, played by other bluetooth devices, etc., i.e., the change of the state information of the audio type corresponding to the audio type of the first target audio data in the available audio context of the bluetooth device may be monitored. As an implementation manner, the bluetooth device is always connected with the first electronic device, the bluetooth device monitors a state change of an available audio context of the bluetooth device, when the state change of the available audio context of the bluetooth device is monitored, the state of the available audio context of the bluetooth device can be updated, the updated state of the available audio context is sent to the first electronic device based on the BLE connection, and accordingly, the first electronic device can determine whether state information of an audio type corresponding to the audio type of the first target audio data in the available audio context is switched from an unavailable state to an available state based on the updated state of the available audio context.

In some embodiments, the first electronic device may monitor the state change of the available audio context in real time, may monitor the state change of the available audio context at preset time intervals, may monitor the state change of the available audio context at preset time points, or may monitor the state change of the available audio context at other preset rules, etc., which is not limited herein.

As one way, the first electronic device may include a bluetooth module and an audio module, and the bluetooth module may transmit the state of the available audio context of the bluetooth device to the audio module if the state of the available audio context of the bluetooth device is acquired. The audio module can determine the audio type of the first target audio data played by the audio module, judge whether the state information of the audio type corresponding to the audio type of the first target audio data in the available audio context of the Bluetooth device is in an available state, and if the state information is determined to be in an unavailable state, play the first target audio data outwards, pause or play the first target audio data through other Bluetooth devices, and inform the Bluetooth module to monitor the state change of the available audio context.

In some implementations, the state of the audio type corresponding to the audio type of the first target audio data in the available audio context of the bluetooth device being the unavailable state may include: an audio type of the audio type corresponding to the first target audio data in the available audio context of the bluetooth device is occupied by the second electronic device. The bluetooth device may further establish BLE connection with the second electronic device, and the second electronic device establishes a connection synchronization stream with the bluetooth device earlier than the first electronic device, so as to transmit third target audio data of the second electronic device, which is the same as the first target audio data in audio type. At this time, the bluetooth device may update the state of the audio type corresponding to the audio type of the first target audio data in the available audio context thereof from the available state to the unavailable state, and send the updated state to the first electronic device, and the first electronic device may consider the state of the audio type corresponding to the audio type of the first target audio data in the available audio context of the bluetooth device to be the unavailable state.

In some implementations, the state of the first audio scene in the available audio context of the bluetooth device as the unavailable state may include: the audio type corresponding to the audio type of the second target audio data in the available audio context of the bluetooth device is occupied by the second electronic device, wherein the audio type corresponding to the audio type of the second target audio data has a higher priority than the audio type corresponding to the audio type of the first target audio data. The Bluetooth device may also establish a BLE connection with the second electronic device, and the second electronic device establishes a connection synchronization stream with the Bluetooth device earlier than the first electronic device, so as to transmit second target audio data of the second electronic device. At this time, the bluetooth device may update the states of the audio type corresponding to the audio type of the second target audio data and the audio type corresponding to the audio type of the first target audio data in the available audio context thereof from the available state to the unavailable state, and send the updated states to the first electronic device, and the first electronic device may consider the state of the audio type corresponding to the audio type of the first target audio data in the available audio context of the bluetooth device to be the unavailable state.

Step S240: and if the monitored first playing capability information of the Bluetooth device indicates that the Bluetooth device is switched from the audio type which does not support playing the first target audio data to the audio type which supports playing the first target audio data, the first target audio data is sent to the Bluetooth device.

In this embodiment, in the process of monitoring the change of the first playing capability information by the first electronic device, if it is monitored that the first playing capability information indicates that the bluetooth device switches from an audio type that does not support playing the first target audio data to an audio type that supports playing the first target audio data, the first target audio data may be sent to the bluetooth device, so as to output the first target audio data through the bluetooth device. For example, assuming that the audio type of the first target audio data is "music type", and the first playback capability information indicates that the bluetooth device switches from not supporting "music type" to supporting "music type", the first target audio data may be transmitted to the bluetooth device.

In some embodiments, determining that the first playback capability information indicates that the bluetooth device switches from an audio type that does not support playback of the first target audio data to an audio type that supports playback of the first target audio data may establish a connection synchronization stream between the first electronic device and the bluetooth device to send the first target audio data to the bluetooth device over the connection synchronization stream.
