Note
See the Overview: Firmware architecture 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 Settings loader module from Common Application Framework (CAF). See the CAF Settings loader module page for implementation details.
Tip
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.
