/**

 * <p>
 * CAUTION:<br />
 * It is very unsafe to call the refresh() method. First of all it's hidden
 * so it may be removed in the future release of Android. We do it because
 * Nordic Beacon may advertise as a beacon, as Beacon Config or DFU. Android
 * does not clear cache then device is disconnected unless manually
 * restarted Bluetooth Adapter. To do this in the code we need to call
 * {@link BluetoothGatt#refresh()} method. However is may cause a lot of
 * troubles. Ideally it should be called before connection attempt but we
 * get 'gatt' object by calling connectGatt method so when the connection
 * already has been started. Calling refresh() afterwards causes errors 129
 * and 133 to pop up from time to time when refresh takes place actually
 * during service discovery. It seems to be asynchronous method. Therefore
 * we are refreshing the device after disconnecting from it, before closing
 * gatt. Sometimes you may obtain services from cache, not the actual values
 * so reconnection is required.
 * 
 * @param gatt
 *            the Bluetooth GATT object to refresh.
