+ * @brief Handling of DFU BLE packets in the application.
+ *
+ * @details This module implements the handling of DFU packets for switching 
+ *          from an application to the bootloader and start DFU mode. The DFU
+ *          packets are transmitted over BLE. 
+ *          This module handles only the StartDFU packet, which allows a BLE 
+ *          application to expose support for the DFU Service.
+ *          The actual DFU Service runs in a dedicated environment after a BLE 
+ *          disconnect and reset of the \nRFXX device. 
+ *          The host must reconnect and continue the update procedure with 
+ *          access to the full DFU Service.
+ *
+ * @note The application must propagate DFU events to this module by calling
+ *       @ref dfu_app_on_dfu_evt from the @ref ble_dfu_evt_handler_t callback.
