 *         freely downloadable from the developer website at
 *         http://software.g-maps.it/
 *         The board will act as Server-Peripheral.
 *
 *         After connection has been established:
 *          - by pressing the USER button on the board, the cube showed by
 *            the app on the smartphone will rotate.
 *
