We are evaluating nRF9160 and need to implement periodic activities
that happen on RTC interrupts. It seems like Zephyr interferes with
normal RTC usage, so my questions are:
- Which RTC is reserved by Zephyr?
- If there is an RTC available for user app, does Zephyr still
intercept its interrupts?
- Zephyr RTC driver looks incomplete (zephyr/include/rtc.h) It
contains deprecated calls and defines based upon CONFIG_RTC_PRESCALER
which is never set. Should I look for working driver elsewhere?
Any advice on implementation of periodic wakeups from WFI in System ON
low power are very much appreciated.
TIA
