GNSS hangs indefinitely

[glenpike]

I'm having problems initialising GNSS on the Hat.

My code is here:

  node = cellulariot.CellularIoTApp()
  node.setupGPIO()
  time.sleep(1)
  node.turnOnGNSS()
  time.sleep(30)
  node.disable()
  time.sleep(1)
  node.enable()

When I interrupt it, the stack trace is here:

  File "src/cosmic_test.py", line 73, in <module>
    main()
  File "src/cosmic_test.py", line 42, in main
    sixfab_sensors.init()
  File "/home/pi/cosmic-pi/src/sixfab_sensors.py", line 10, in init
    node.turnOnGNSS()
  File "/usr/local/lib/python3.7/dist-packages/sixfab_cellulariot-1.2.0-py3.7.egg/cellulariot/cellulariot.py", line 421, in turnOnGNSS
  File "/usr/local/lib/python3.7/dist-packages/sixfab_cellulariot-1.2.0-py3.7.egg/cellulariot/cellulariot.py", line 206, in sendATComm
  File "/usr/local/lib/python3.7/dist-packages/sixfab_cellulariot-1.2.0-py3.7.egg/cellulariot/cellulariot.py", line 30, in millis

I have the antenna plugged in, I am testing it outside, under cloudless sky and I have a SIM card inserted.

Should I be checking satellite coverage for my area, or is there something else I need to do or a way of checking?
