NEO M8T with RTKRCV on Raspberry Pi3

Hello, everyone!

I am currently doing a university project and my goal is to find the position of a rover in real time.

My set up is the following: 2x NEO M8T boards connected to a Raspberry Pi 3 (updated to latest version GNU/Linux 8).

The reason that they are both connected to the Pi is that I am not sure that my SiK telemetry transmits anything as even in RTK Navi on a laptop I don't get base station data. (the radios are matched)

The M8Ts are set to 115000 baud rate by using u-center (latest version). NMEA messages are turned off and UBX messages are turned on.

I installed the latest version of RTKLIB from tomojitakasu's github on the Pi. Ran make in the rtkrcv folder.
Ran chmod +x rtkstart.sh and chmod +x rtkshut.sh as it wanted permissions.

Started rtkrcv with sudo ./rtkrcv

I get "invalid option value pos-1snrmask" but the program still runs.
I run a conf file which I created but I DONT KNOW if it is correct.

It says "startup script ok" "rtk server start error" and thats it... nothing else.
The conf file I use is as following:
