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.

See the Application overview for more information about the event-based communication in the nRF Desktop application and about how to read this table.

Implementation details

nRF Desktop uses the simple management protocol module from Common Application Framework (CAF). See the CAF module page for the implementation details and guide on how to perform the firmware update in the nRF Connect Device Manager application.
