Yes, we support it. The recommended way to connect both profiles is to simply use the org.bluez.Audio.Connect() D-Bus method. You'll need to have some integration with the actual telephony subsystem (e.g. skype in your case) as well as some extra handling in the component that interfaces with bluetoothd over the audio unix socket (pulseaudio/gstreamer/alsa/etc). Your media player should probably also be telephony aware or at least provide an interface to a component that is telephony aware so that the playing can be paused for the duration of a call. In Maemo 5 this all works quite well by using the bluez maemo telephony driver and a special pulseaudio policy module which handles the stream switching on the pulseaudio side. Even with upstream pulseaudio on my Ubuntu laptop I can get the profile switching somewhat well working with the help of the pavucontrol tool. > Is this feature available in BlueZ? If so from what version of BlueZ? In theory any 4.x version should be fine, but the newer the version the higher the chances that it'll work well. Johan
