[Bluez-devel] avrcp start

Hi

I've started an avrcp receiver in the btsco cvs.

I hope it doesn't seem like a case of extreme laziness to put the sdp
stuff in sdptool. I suppose I should get serious and put it in my app
too. Did I write the patch right with regard to protocol names, etc?

Also, is there a separate UUID for AVRCP? I only found AVCTP UUID
definitions, but it seems like PID in the AVCTP header needs to indicate
AVRCP specifically.

With the changes above, I got my headset to connect but it seems to put
in the value "0e11" for the pid in the first AVRCP packet I got out of it.

Brad
