Hello.My first test was with usb cable with my pc and PuTTY (COM 15 for me) with Sony Ericsson W995.Today open bluetooth PC and mobile phone and type AT*SEJCOMM=1,1 and work fine with bluetooth without cable.I use BlueSoleil Serial Port Services.I believe i can use my phone as BT shield for communication with more arduinos BT.(Network with arduino BT).My phone has GPS,camera,motion sensor,clock,calendar,sd card,voice,audio,sms,mms,e-mail ... with suitable program javame can work these.Thanks.
