I am starting to dig into all the components of this shield. The GPS appears to be working, but never receives a fix.
When using the GPS python script from the tutorial, I continuously get the following:
No satellite data available.
I have also tried using the cellulariot python package too from your Git repo with the following code:
from cellulariot import cellulariot
node = cellulariot.CellularIoTApp()
I receive the following response:
+CME ERROR: 516
I have tried both the provided GPS/LTE antenna and an active antenna. I have tried moving the device to the window and even left it in the backyard for a few hours with a big battery pack, but never received a fix. I tested the antennas with an Adafruit Ultimate GPS and was able to get a fix with both antennas within a minute, even indoors by the window.
What further steps can I take to diagnose the issue?
