My BT CPL does look like the one you posted so I'm guessing it is the MS stack. I will try to confirm positively tommorrow, but either way I would love to see that source. If it does nothing but give me some concept of how to go about this, then I'd be happy. If your code gets me a good part of the way there, then even better. I did look at the A2DP app you mentioned (the CLI one), but it doesn't appear to have the ability to initiate an A2DP connection to a specific device. Did I miss something or could you have been misunderstanding what I am seeking?
Mike (PS I think you have the makings of a unique app that will be very much appriciated as more people come to see the potential of A2DP and I'd very much like to contribute any way I can to that code or interface just to say I did.)
