Re: after Deep Sleep ESP32 - Time offset

I also tried an other rtc library now ..with the same result (RTClib)
so the problem must be somewhere else..

what i thought .. is that i set the clock in the setup() 10 minuts less .. so it would set the clock after the deepsleep back .. but i do not think this is the best solution

Re: after Deep Sleep ESP32 - Time offset

i really don´t understand why this happens, because at daytime i measured a offset of eg. max +3 seconds over 12 hours (while controller is running). I know its also not a good offset but wouldn´t be as bad because in the final program i do a sync with the ntpServer (but it´s not always possible to ...

Re: after Deep Sleep ESP32 - Time offset

thanks for your replay! my setup: external RTC 1307 on the controller. No alarm function on hardware side available, therefore the ESP should use the internal timer (RTC from the controller) and should than go into the DeepSleep when waking up, the clock should be used again by the external RTC. The...

after Deep Sleep ESP32 - Time offset

Has anyone already noticed a similar problem?
i leave my esp32 for 9 hours in the DeepSleep and after waking up (with its timer) is a time offset of the RTC of +10 minutes and a few seconds.

i have a rtc clock which works fine before switching in DeepSleep (no offset).
