org.bluez.audio.Manager interface
=================================
This interface is for managing remote audio devices. It provides methods for
creating and removing D-Bus objects representing remote audio devices. These
objects implement one or more of the other interfaces listed in this document.
Object path /org/bluez/audio
Methods
string CreateDevice(string address) [experimental]
Creates a new audio device object. If not yet done,
this method will perform a SDP query on the remote
device and return first when the query is complete,
so be sure to call this method asynchronously.
The return parameter is the object path of the newly
created object.
void RemoveDevice(string path) [experimental]
Removes a device from the device tree. If there are
any connections open to the device they will be closed.
array{string} ListDevices(array{string} interfaces) [experimental]
Retuns an array of strings indicating the object paths
of available devices which implement as a minimum the
interfaces given through the parameter.
string DefaultDevice()
Returns the object path for the default device.
void ChangeDefaultDevice(string path)
Changes the default device.
array{string} ListHeadsets()
Returns list of headset objects that are configured.
string FindDeviceByAddress(string address) [experimental]
Searches the list of available devices and returns the
object path of the first device which matchess address.
If no device is found returns a DoesNotExist error.
string DefaultHeadset()
Returns the object path for the default headset device.
void ChangeDefaultHeadset(string path)
Changes the default headset.
string CreateHeadset(string address)
Create a new headset device and returns its object path
on return.
void RemoveHeadset(string path)
Removes a headset object and all information
related to it.
Signals
void DeviceCreated(string path) [experimental]
Sent when a new device object has been created.
void DeviceRemoved(string path) [experimental]
Sent when a device object has been removed.
void HeadsetCreated(string path)
Sent when a new headset object has been created.
void HeadsetRemoved(string path)
Sent when a headset object has been removed.
void DefaultHeadsetChanged(string path)
Sent when the default headset has changed.
org.bluez.audio.Device interface
================================
This interface is implemented by all remote device objects.
Object path(s) /org/bluez/audio/device*
Methods string GetAddress() [experimental]
Returns the Bluetooth address of the remote device.
array{string} GetConnectedInterfaces() [experimental]
Returns a string list of interfaces that are in a
connected state.
org.bluez.audio.Headset interface
=================================
This interface provides access to headsets that implement the HSP and/or HFP
profiles.
Object path(s) /org/bluez/audio/device*
Methods void Connect()
Connect to the HSP/HFP service on the remote device.
void Disconnect()
Disconnect from the HSP/HFP service on the remote
device.
boolean IsConnected()
Returns TRUE if there is a active connection to the
HSP/HFP connection on the remote device.
void IndicateCall()
Indicate an incoming call on the headset
connected to the stream. Will continue to
ring the headset about every 3 seconds.
void CancelCall()
Cancel the incoming call indication.
void Play()
Open the audio connection to the headset.
void Stop()
Close the audio connection.
boolean IsPlaying()
Returns true if an audio connection to the headset
is active.
uint16 GetSpeakerGain()
Returns the current speaker gain if available,
otherwise returns the error NotAvailable.
uint16 GetMicrophoneGain()
Returns the current microphone gain if available,
otherwise returns the error NotAvailable.
void SetSpeakerGain(uint16 gain)
Changes the current speaker gain if possible.
void SetMicrophoneGain(uint16 gain)
Changes the current speaker gain if possible.
Signals void AnswerRequested()
Sent when the answer button is pressed on the headset
void Connected()
Sent when the device has been connected to.
void Disconnected()
Sent when the device has been disconnected from.
void Stopped()
Sent when the audio connection is closed
void Playing()
Sent when the audio connection is opened
void SpeakerGainChanged(uint16 gain)
The speaker gain changed.
void MicrophoneGainChanged(uint16 gain)
The microphone gain changed.
org.bluez.audio.Gateway interface
=================================
[not yet implemented]
This interface is available for remote devices which can function in the Audio
Gateway role of the HSP and/or HFP profiles.
Object path(s) /org/bluez/audio/device*
org.bluez.audio.Sink interface
==============================
This interface is available for remote devices which contain a A2DP Sink.
Object path(s) /org/bluez/audio/device*
Methods void Connect()
Connect and setup a stream to a A2DP sink on the
remote device.
void Disconnect()
Disconnect from the remote device.
boolean IsConnected()
Returns TRUE if a stream is setup to a A2DP sink on
the remote device.
Signals void Connected()
Sent when a successful connection has been made to the
remote A2DP Sink
void Disconnected()
Sent when the device has been disconnected from.
org.bluez.audio.Source interface
================================
[not yet implemented]
This interface is available for remote devices which implement a A2DP source.
Object path(s) /org/bluez/audio/device*
org.bluez.audio.Control interface
=================================
[not yet implemented]
This interface is available for remote devices which implement support for a
AVRCP controller.
Object path(s) /org/bluez/audio/device*
org.bluez.audio.Target interface
================================
[not yet implemented]
This interface is available for remote devices which implement support for a
AVRCP target.
Object path(s) /org/bluez/audio/device*
