GPS-RTK-SMA: RTCM3 correction with a basestation and a rover

GPS/GNSS Development Boards
1

I have two GPS-RTK-SMA boards and I’m trying to use one as a basestation and the other as a rover.

The example code lets me receive the RTCM3 data over I2C, which I’m forwarding to a second microcontroller that sends it to the UART RX2 pin of the Rover GPS module. However, it isn’t working, the accuracy is not improving.

I was surprised to see that the example codes don’t show how to load the RTCM3 data into the rover GPS module. How can this be achieved?

Thanks!
