Implementation details

nRF Desktop uses the Settings loader module from Common Application Framework (CAF). See the CAF Settings loader module page for implementation details.


Enabling CONFIG_CAF_SETTINGS_LOADER_USE_THREAD is recommended for keyboard reference design (nRF52832 Desktop Keyboard). The CAF: Buttons module uses the system workqueue to scan the keyboard matrix. Loading the settings in the system workqueue context could block the workqueue and result in missing key presses on system reboot.
