Script stops functioning after calling irsend() function in irlibrary! I have the following script which checks if the user has pressed the numbers "770" or "769" continuously in the remote. The script works fine and displays all numbers. When I press the buttons "770" or "769" continuously the function powerOff() is called and I get no serial input.

Apparently you should be calling irrecv.enableIRIn() after sending, not irrecv.resume(). Sorry for suggesting the wrong thing on IRC before :-)
