Ublox 6T cannot Achieve FIX solution


Im trying to get FIX solution on ublox 6T RTK
the setup im using is (4) RTK‐GPS/GNSS, input rover data from a serial port and input base‐station data from a remote receiver via Wi‐Fi network. but my issue that the solution is always Single and only 8 satillite are shown.

For the rover I’m using Kenimetic positioning and Fixed for the base.

How can I get FIX solution in RTKNAVI? What am I doing wrong?
