/**
 * @brief  Main function to show how to use the BlueNRG Bluetooth Low Energy
 *         expansion board to send data from a Nucleo board to a smartphone
 *         with the support BLE and the "BlueNRG" app freely available on both
 *         GooglePlay and iTunes.
 *         The URL to the iTunes for the "BlueNRG" app is
 *         http://itunes.apple.com/app/bluenrg/id705873549?uo=5
 *         The URL to the GooglePlay is
 *         https://play.google.com/store/apps/details?id=com.st.bluenrg
 *         The source code of the "BlueNRG" app, both for iOS and Android, is
 *         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.
 *          
 *         The communication is done using a vendor specific profile.
 *
 * @param  None
 * @retval None
