I'm having some trouble with MediaEndpoint/MediaTransport and A2DP. When I get the "SetConfiguration" call, I wait 2 seconds and then call "Acquire", generally giving BlueZ enough time get the D-Bus interface ready to go. However, the delay isn't always long enough. Shown below is a time when my phone is attempting to pair with BlueZ. The error "org.bluez.Error.NotAuthorized" is output from my application. In this case, the problem is that the audio source is still in the CONFIGURED state, not in the OPEN state. Is there a recommended method of how long to wait before calling acquire? Or should I rely on the AudioSource "State" property to become connected (or playing)? Is there any reason I can't get the transport when in the Configured state (does the fd not exist yet?)? Or why is "a2dp_resume" being called on open (which is what is rejecting my acquire call)?
