When your device wakes up from system off sleep it will reset. This means that it will redo all initializations, and your buttons will be configured the way you set them to.

Startup: Button configured to push, release, long push

System_off_sleep: Button configured to wakeup

When button is pressed the application returns to startup and your button will be configured to push, release and longpush again

When your device wakes up(reset) it will go through your main function and it's initializations again, this will make your actions assigned once again. That means that wakeup function is removed when you wake up

Hi,

See the tutorial on the Board Support Package. When you enter sleep mode you prepare a wakeup button like this

err_code = bsp_wakeup_buttons_set((1 << WAKEUP_BUTTON_ID));
APP_ERROR_CHECK(err_code);

When you go to sleep the system will now reset when your button is pressed. This means that your button will do what it was configured to do in your init functions.

Best regards,

Øyvind
