Hello,
I just purchased the LTE CAT M1/NB-IoT shield along with the UBLOX SAM-M8Q.
The issue i have is when using sketch 05 or 06 the sketch only reads the Time/Date correctly.
Position is never read.
I am using Arduino 1.8.12.
Any direction is greatly appreciated.
Thanks

Hello.
It looks like the GPS has enough satellites to get the time, but doesn’t have a strong enough signal to get it’s position. I had the same issue here with the GPS sitting in a window indoors.
You might try taking everything outside in the open away from trees and buildings to see if you can get a stronger signal. Holding the GPS in the palm of my hand (with the antenna facing the sky) seemed to help with reception.

You were right.
We test all of our gps units in the same physical location but this one wants to actually be outside! Its a nice day so maybe that’s the reason.
By the way we have been looking at the libraries but don’t see a specific reference for Status & Mode.
My assumption of Status is derived from the NEMA output sentences: Status A=active or V=Void.
Same assumption for Mode: A=autonomous, D=differential, E=Estimated, N=not valid, S=Simulator
Thanks for your quick response!
By the way everything else seems to work fine.
