Description

Hi folks,

I'm watching my GPS time on my SenseCap Indicator which is connected to an Air530 GPS from SeeedStudio. This is all supported hardware.

The GPS time does NOT regularly sync. Maybe once a day or something? It is constantly off and is almost never correct. Right now my device clock is off by over 40 seconds. Watching the serial output from the GPS unit, the time is very close to correct (well, maybe ~250ms off from the serial delay).

If GPS time is available and the device has a good fix. The device should prefer GPS time over mesh time. (Or maybe use NTP if NTP is set... unless there is a preference added for clock source.)

It seems to do none of these things. I'm guessing it's synchronizing like once every 24 hours. Either we should synchronize GPS time every time position is updated, or we should have a way to prefer NTP time.

Having the wrong time continually on a GPS connected device is suboptimal.

Thanks,

Thanks for sending in a report. I have that hardware and will try to reproduce.
