hello people..

I got his developer kit from TI containing a BRF6150 chip.. and i was trying to write code in VC++ to make headset profile over the HCI interface...
I am able to make it do most of the things like search, connect, blah blah...
the problem (not exactly a problem) comes when I try to connect to a headset. It connects but I am not able to aend any AT commands to it using which i can send messages like call connect etc. I understand that crating a connection will only create a service level connection. To make it work I have to create an RFCOMM connection. For that I need the RFCOMM channel ID, to get it i have to run an SDP and find out the channel ID etc.... but i have no clue how to do this..
can anyone help please
thanx in advance
