I have one of those. It takes a lot of work writing embedded C code to make it do what you want. In my case it was displaying a calendar and the moonphase. The default software is very bare bones. Battery life is 1.5 weeks for me when using ntp sync once a Day and a display update every minute without any further wireless communication.
I find the PineTime more attractive because it has an aditional heart rate sensor and a color display with similiar battery life.
- daneel_w 3y agoThe 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 for eventualities?
- sprash 3y 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 3y 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.
