I need help with my GSM-module. I am using the SIM7600E-4G-HAT module from Waveshare and I am unable to recieve GPS-Data by using the AT-Commands from the manual. The GPS-Antenna is connected to GNSS at the board. I am interfacing the module with the Arduino IDE (Serial-Monitor) and tried the following:
14:40:54.375 -> at
14:40:54.375 -> OK
14:40:57.410 -> at+cgps?
14:40:57.410 -> +CGPS: 0,1
14:40:57.410 ->
14:40:57.410 -> OK

Previously I was able to get the GPS-Data, but it stopped working somehow. I already thought that either the GPS-Antenna could be broken or I messed up some setting by the AT-Commands. Here are links to all AT-Commands and to the Manual:

I've finally solved the problem. The coaxial cable was defect, so I replaced it and now it works. I don't know the exact reason for this, it could've been due to the HF or no contact.
