I have a (hopefully) simple question about the GPS module and NTP. So I have a RS 1D and the recommended GPS module and had previously booted it all up in the correct order and got the RS ostensibly getting its NTP from the GPS. I double checked with the ntpq -p command and it had the asterisk by the PPS and everything. My understanding was that now that that was all set, I could boot up my RS without being connected to the internet and it would just get its timing from the GPS from here forward.
However, that does not seem to be the case and when I rebooted the RS it started up as if it was being turned on without a connection (Case 1 from the NTP and GPS page of the RS manual) and resumed with the UTC time beginning from the time it was at when it shut down. Using the ntpq -p command again, I was able to see that while it is configured to see the GPS it is no longer being used for the time or is not connecting for some reason and the asterisk has vanished (see below for results of the ntpq -p command now).
So my question is essentially, why does the Raspberry Shake not automatically connect to the GPS when it has been previously set up and how do I remedy this for when the GPS may need to be rebooted or shut down in the field and I will not have a router to plug it back into?
Thanks so much for any and all help!
