Simple Management Protocol module

The simple management protocol module is responsible for performing a Device Firmware Upgrade (DFU) over Bluetooth® LE.

You can perform the DFU using for example the nRF Connect for Mobile application. The DFU button appears in the tab with the connected Bluetooth® devices. After pressing the button, you can select the *.bin file that is to be used for the firmware update.

Implementation details

nRF Desktop uses the simple management protocol module from Common Application Framework (CAF). See the CAF module page for implementation details.
