hi, thanks for your comments.
I finally success to access to the Arduino BT via XP SP2 bluetooth driver just "one" time after several try,
I just borrow my friend's Arduino BT and can pass the pass key "12345", but mine still can't...is that mine has some problem....
by the way, i try another driver "bluesoleil", but the boards still couldn't be access, so i wanna ask which driver did you use, so i can try it.
additional question: do you know how to reset the board to the default setting? Because i am afraid that my board's passkey may have some problem...
the guide from the arduino.cc said that the reset pin is pin 7, do you know what steps should i do to reset it?
thanks
regards,
Shek
