Hi all, I used RTC for my PSoC4 BLE project. And I used deepsleep mode. Now I faced an issue. After deepsleep mode the RTC can only hold the time information before the device goes into deepsleep mode. Does RTC run in DeepSleep mode in PSoC4 BLE?

RTC does not run in deep sleep. You should manage to wake up every second, increase the RTC and go to sleep again.

Hi Bob,

Really thanks for your reply. So I need to wake up from WDT interrupt and then need to update the RTC. Is that right?

Yes; If you set your deep-sleep WDT to 1 second, and wakeup to increment the RTC each second that should fix the RTC not running while asleep.
