Hello,  
I am testing a HL7800 module on the MangOH Red. I am not able to get a position fix from the device.

at+gnssloc?  
+GNSSLOC:  
FIX NOT AVAILABLE  
OK

I have the included external patch antenna connected and I am outside.

at+gnssconf=?  
+GNSSCONF: 1,(0-1)  
+GNSSCONF: 10,(0-1)  
OK

Any thoughts?

Looks like cellular needed to be disabled with CFUN=4 and now GNSS works…
