Thank you for your valuable info.
I've removed the BlueSoleil program, and let the MSWindows XP handle the BT.
I'm still in the process of establishing the connection which is incomplete, I guess.
Since I am not quite familiar with BT's procedure, I was a bit confused about the serial port selection for "Sending" or "Receiving" port. "Receiving" has been selected for ARDUINOBT, which is given password of predefined '12345.' "Sending" has been selected for other port.
Am I supposed to select the ports separately, one for sending, the other for receiving?
With the BlueSoleil, I just selected one port for communication, as in the case of WiTilt2.5 accelerometer breakout board from Sparkfun, which is working fine for me.
Sorry for my newbie question.
Appreciate your interest in this regard.
