Treo,
This is the same crap explanation they tried to give as to why we could not get Caller ID announement over our BT headset.. although they did go even farther by saying there is only one audio path that sends and receives.. blah blah blah. As I have found they are full of SLACK!
If you have .NET 2.0 installed on your phone I'm pretty sure we can get this to work. Give me some time here and your help with debuging it (I don't have the Treo and I can't test BT thru the emulator) and I'm sure we can get this working. Already I know a way to make it work! It was the first sample I made for the ppc. I don't know what time it is where you are, but let me get the kids settled and I'll make the program and send it to you, or post it here for a test run.
We will get it figured out!
