SimpleControls works with the BLEController iOS/Android App. The mbed's pin can acts as DIGITAL_IN, DIGITAL_OUT, PWM, SERVO, ANALOG_IN. The sketch is to show you how to control the pin as one of the abilities. Note that not every pin can own all of the abilities.
Dependencies: BLE_API mbed nRF51822
