Hi,
i have bluetooth stack and sample progrmme of file transfer is not happening in this code, please can u help me to get the solution.
thanks
remove the “not” in your statement and you are fine 
Siriously, within your statement you do not describe a problem, nor do you ask what kind of help you need.
The only thing i can read of it: You have a BT-Stack and a Sample application for file transfer. Something is not working.
With this assertion i would reply in the way of a support line: Is it plugged in?
