Open The Door

Turn on the bluetooth on your phone, connect and send the passkey to the slave device to open the door.
Configuration is stored in text file named remotecfg.txt located in the root of 1st external storage.
It contains the mc address of the slave and the passkey to send, example:
4C:ED:DE:6D:AC:81
12345

After sending the code, the app will restore the bluetooth state as before app starts then app closes.
The key point is to open the door by only one touch on the app icon.
