In RTK you have base and rover receivers. Rover can move freely but base
must stay at a known position.

I have not used u-center (it is non-free) but can you try setting
"Protocol out" to "UBX"?
Then you also want to enable periodic RXM-RAW and RXM-SFRB
reports. These should be in CFG-MSG. Look for "Rate" and set it to
something non-zero. (I am just guessing here since I really have never
even seen u-center).

Is the GPS receiver sending anything over the serial port? If not, you
can't blame rtklib :-)
