I have a Adafruit FONA 3G/GPS module ([American Version](https://www.adafruit.com/products/2687)). I have gotten the cellular functionality to work but I am struggling with GPS. I have tried both passive and active antennas.

This is a list of AT commands that are available to the SIM5320A module ([pdf](http://simcom.ee/documents/SIM5320/SIMCOM_SIM5320_ATC_EN_V2.02.pdf)). The Adafruit example code uses AT commands that don't run on this SIM module. I send the following sequence:

```
AT+CGPS=1,1

AT+CGPSINFO

and I am receiving:

+CGPSINFO: ,,,,,,,,

AmpI/AmpQ: 4xx/4xx

```

What exactly is going wrong? I am connected but am not getting any data out. Also, I understand the mathematical significance of AmpI/AmpQ but what does that mean in terms of connection to GPS network?
