System on RTC wakeup

[osmpradeep_]

 Is possible to wake up the device by RTC Event? For example, put device(battery powered) in deep sleep for some duration(disable all peripherals to increase battery life) and after that time wake it up? please give examples for this.

Hi,

Wakeup from RTC can only be achieved in System ON idle mode (__WFE() or sd_app_evt_wait(). In System OFF sleep mode, all clock sources are stopped, and the IC can only be woken by the peripherals described in the documentation.

Best regards,
Jørgen
