Bluetooth Low Energy / Mbed 2 deprecated BLE_Button

A template for applications where some small amount of data needs to be notified to a phone app over BLE. It is a good starting point for notifications.

Dependencies:   BLE_API mbed nRF51822

Demo for an Input Service

To help you create your own BLE services, we've created a series of service templates. The *input service template* demonstrates the use of a simple input (boolean values) from a read-only characteristic.

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-only, boolean, with notifications. This characteristic is updated according to the button's state.

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