 *
 * @brief DFU BLE packet handling for application.
 *
 * @details This module implements handling of DFU packets transmitted over BLE for switching from 
 *          application mode to Bootloader running full DFU service.
 *          This module only handles the StartDFU packet allowing for any BLE application to expose
 *          support for the DFU service.
 *          Actual DFU service will execute in dedicated environment after a BLE disconnect and 
 *          reset of the nRF51 chip.
 *          The host must then reconnect and can continue the update procedure with access to full
 *          DFU service.
 *
 * @note The application must propagate dfu events to the DFU App handler module by calling
 *       dfu_app_on_dfu_evt() from the from the @ref ble_dfu_evt_handler_t callback.
