help me , how can use RTC in sleep mode

[calivan]

before the question , I hope you understand my poor English.

i make  a project using nrf52840 dongle 

when event of an interrupt signal occur  ,  the chip must wake up and generate type-1 beacons.

and,  type-2 Beacon signals should be generated every four hours.

so , i have some questions

on deep sleep mode, can i use RTC ?

if not 

how can i use RTC in system on lower power mode ?

and... can you recommend  some examples in SDK that related my project ?

thank you for your understand my poor English

Hi,

All timers are disabled in SYSTEM OFF sleep, however you can set the nRF to SYSTEM ON sleep where it will consume very little power while it waits for an event. I suggest that you see the Real Time Counter example in the SDK as it implements exactly this. You can find the documentation on the feature here.
