"After you install one of these Bluetooth SPP apps, you can pair with your bluetooth modem connected to the Arduino. If it asks for a key, it will usually be by default "1234" (without quotes of course). After that, you should beable to send ABCD and the door strike will unlock for around 5 and 1/2 seconds, and then lock itself again."
