* @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.
