Bluetooth Sco Audio Disconnected Bluetooth Audio Gateway
Or disconnect occurred (due to HW problem or problem on.The QBluetoothAudioGateway class provides an interface to a Bluetooth Audio Gateway.The Bluetooth Audio Gateway usually has an audio device associated with it. This issue happens for several reasons, which is why you’ll need to review the circumstances that occurred immediately prior to this issue happening.This means that either local side (pulseaudio) or remote side (your headset) closed audio connection. It can be frustrating to be listening to your favorite song when the headset suddenly says, Bluetooth disconnected. For example, this intent may be sent when a wired headset is unplugged, or when an A2DP audio sink is disconnected, and the audio system is about to automatically switch audio route to the speaker.DeviceHeadphoneMicrophoneBlueZ VersionAfterShokz TREKZ TitaniumYesNot tested5.50r2AKG N700NCYesNot tested5.52Beats By Dre PowerBeats3YesNot tested5.55View 53 more rows2 protected variables inherited from QObjectThe Bluetooth headset keeps disconnecting. Broadcast intent, a hint for applications that audio is about to become 'noisy' due to a change in audio outputs.
If there is more than one service that supports bluetooth audio gateway, the caller should enumerate them with QCommServiceManager::supports() and create separate QBluetoothAudioGateway objects for each.See also QAbstractIpcInterfaceGroup::supports(). The object will be created in client mode if mode is Client, or server mode otherwise.If service is empty, this class will use the first available service that supports bluetooth audio gateway. A Bluetooth Audio settings application.)Member Function Documentation QBluetoothAudioGateway::QBluetoothAudioGateway ( const QString & service = QString(), QObject * parent = 0, QAbstractIpcInterface::Mode mode = Client )Construct a new audio gateway object for service and attach it to parent. This class should be used by client applications that wish to control the state of Handsfree / Headset implementations (e.g. Both use a control RFCOMM channel and a SCO voice data channel.
Use audioEnabled() to find out the state of the audio stream.See also audioEnabled(). The audio stream (SCO connection) has been disconnected or connected. Void QBluetoothAudioGateway::audioStateChanged () This signal is emitted whenever the state of the audio data stream has changed. All audio information should now be routed over the device associated with this audio gateway.See also isConnected() and remotePeer(). This is true once an SCO connection has been established between the remote device (headset) and the audio gateway. Bool QBluetoothAudioGateway::audioEnabled () constReturns whether the voice data information is being passed to the device.
All audio data should now be routed to the associated audio device.See also releaseAudio(). Void QBluetoothAudioGateway::connectAudio () Asks the Audio Gateway to establish an SCO data connection with the currently connected peer. The addr contains the address of the remote device and rfcomm_channel contains the service channel to connect on.The connectResult() signal will be sent once the connection succeeds or fails.See also connectResult().
Void QBluetoothAudioGateway::headsetDisconnected () This signal is sent whenever a headset has disconnected from the audio gateway.See also disconnect(). The headsetDisconnected() signal will be sent once the headset is disconnected().See also headsetDisconnected(). Void QBluetoothAudioGateway::disconnect () Disconnect the currently active client from the Audio Gateway. If the connection failed, the msg parameter holds the error string.See also connect(). The success parameter is true if the connection succeeded, and false otherwise.
Void QBluetoothAudioGateway::microphoneVolumeChanged () This signal is sent whenever the microphone volume of the remote device has been changed.See also microphoneVolume() and setMicrophoneVolume(). The volume can be between 0 and 15.See also setMicrophoneVolume(). Int QBluetoothAudioGateway::microphoneVolume () constReturns the current microphone volume of the device. This is true once an RFCOMM control connection has been established between the remote device and the audio gateway.See also audioEnabled() and remotePeer().
No audio should be routed through the associated audio device.See also connectAudio(). Void QBluetoothAudioGateway::releaseAudio () Asks the Audio Gateway to release the SCO audio data connection. The addr parameter holds the address of the connected remote device.See also connect(). It is only sent on remote device initiated connections.
Void QBluetoothAudioGateway::speakerVolumeChanged () See also speakerVolume() and setSpeakerVolume(). The volume can be between 0 and 15.See also setSpeakerVolume().
