This app is not for normal users.
BluCon sends/receives commands to MCU(arduino) equipped with a bluetooth module through SPP(Serial Port Profile).
There are 3 modes to communicate with remote devices, which are hybrid, accelerometer and touch mode.
All buttons(F1,F2 and F3) are working as same way on those 3 modes.
On Hybrid, by pressing forward/reverse button with your phone tilted to left or right, you can send commands.
On accelerometer, by tilting your phone, you can send commands.
On touch mode, by dragging red circle inside big circle, you can send commands.
Before send commands, pairing should be made.
BluCon will remember a last bluetooth device connected and re-connect when re-launched.
