the reason why i am contacting you all is that can anyone of u help me in solving one problem on which i am stuck since few days that i am trying to built up bluetooth system with combination of Arduino MEGA 2560 and BLUEGIGA-WT32, which can establish speech communication b/w my system and bluetooth handsfree device ( in-car handsfree system).

So help which i am looking forward from you is that i am willing to use laptop built in mic and speaker for communication purpose instead of attach external audio/mic amplifier  to my arduino or BLUEGIGA unit. these days i m working on processing program to find answer for problem
