The schematic shows an RTC in there, does it really need to have its timekeeping syncronized every day next to startup?! Or it's just something you do to cover

- sprash 4y agoMaybe I'm doing something wrong but the RTC lags about a minute every three days. At least for my device a regular ntp sync is therefore absolutely required.
- charlesrocket 4y agoSome v1 units got defective RTCs so one would have to frequently sync time. My version had around 2 weeks of battery life (no ntp/etc). I can see getting way beyond that with accel and on-demand refresh instead of 1min intervals.
