Ublox + NMEA GPS Not working

I have this GPS and this FC:

Gps is No Fix and Compass is unhealthy. Mission Planner doesn’t see any compass in the list. I probably need to adjust something via U-Center. Is that the case? Alternatively where what and how?

EDIT: I don’t have a cable for the GPS and the TCP connection doesn’t work.
