RTK with Emid Navio2 as rover and base

Hi, I want to use Raspberry pi with Navio2 hat for rover, and one more for base. But i struggle a bit, as a new user. My plan is to get they to work together to get gps corretions (altso wenn I disconnect my laptop).
I use telemteri radio kit, one on the rover (uart) and one on the base (uart by the usb). And both system is configuret with the same image, and “rover 4.0.”
Anyone that have tried it, and have some sugestions on how to get it to work?
