I've managed to get Raspberry Pi 4 working with Sim7600e similar to https://tutorial.cytron.io/2019/09/04/a ... 0e-module/.
However, the GPS coordinates received seems to be 30km off.
There are 3 mode for the GPS session:
- standalone
- UE-Based
- UE-Assisted
For the 3rd mode, I did the following:
- AT+CGDCONT= 1,"IP","diginet","0.0.0.0",0,0
- AT+CGPSURL="supl.google.com:7276" # set agps url
- AT+CGPSSSL=0 # set security mode
- AT+CGPS=1,3 # start gps in assisted mode
I am trying to improve the accuracy of the GPS. Anyway that I can achieve this?
