DuyLionTran 0:64ca984b3efd 2 * This is the code for "BLE Device for motorbike". The device is attached on any bike at will.
DuyLionTran 0:64ca984b3efd 3 * User can control 2 switches and these switches can control anything that user wants ie: turn on
DuyLionTran 0:64ca984b3efd 4 * the bike, turn on the alarm system of the bike, turn on the light...
DuyLionTran 0:64ca984b3efd 5 * Temperature sensor is also included in the device. User can view the temperature when he/she gets
DuyLionTran 0:64ca984b3efd 6 * near the bike.
