Please ensure BLUETOOTH is ENABLED before you use the app.(Fix coming soon).
This application will auto-connect with your HC-05 Bluetooth module and send 'A'-'D' for ON and 'a'-'d' for OFF using toggle buttons in the Main Activity.
Simple to use. Very Lightweight. Lets you concentrate on your Electronic front.
Ensure HC-05 is already Paired with Phone. (Typical pin is 1234 or 0000 while pairing HC-05).
Completely automated. Just launch and use with the auto-connect feature.
