template for an actuator service

Dependencies:   BLE_API mbed nRF51822

Demo for an Actuator Service

To help you create your own BLE services, we've created a series of service templates. The *actuator service template* demonstrates the use of a read-write characteristic to control a LED through a phone app.

The template covers:

1. Setting up advertising and connection states.

2. Assigning UUIDs to the service and its characteristic.

3. Creating an input characteristic: read-write, boolean. This characteristic offers control of the LED.

4. Constructing a service class and adding it to the BLE stack.
