RTK Base and Rover with UM980 Module (Only Navigation)

Hello! I bought an UM980 RTK module from AliExpress (BDLX gnss), and i would like to create a base, and a rover too. My idea was creating the base first with a Raspberry Pi, you know RTKBase from github. And i would like to know, what to configure on the module to work with that.

The next question of mine is the rover. I want to use another UM980 for that too, and same here, would like to know what to configure on the rover to work with AgOpenGPS.
(For now, i just want navigation without Autosteer)
