You mean just dummy this function "sleep_mode_enter()",

just use the "idle_state_handle()" function which could be found in the main loop?

Hi,

You can use CPU sleep for power saving mode instead of using System-Off. This is for instance done in the Power Profiling Application, which demonstrates how both modes can be used. When using CPU sleep, the application uses the sd_app_evt_wait function, which places the chip in 'Low Power' mode, and the chip will wake up on application interrupts. I would recommend checking out how this is done in the Power Profiling application, as well as reading the documentation for sd_app_evt_wait that I linked.

Best regards,

Marte
