If this is POWER ON SLEEP (WFI/WFE equivalent) then you should get RTC counter compare interrupt if you set everything properly. If you talk about SYSTEM OFF mode then RTC is stopped there and won&#39;t wake you up. There are RTC examples in SDK, which exactly do you use?</p><div style="clear:both;"></div>
