TRK-MEAS and TRK-SFRBX messages have been used for RTK on Navio+.
I thought the issue was the IMU and GPS buth using the SPI (reff.in the link below) and the new aux SPI controller would fix it.
Is there another hardware issue or is it some software problem that the community could work on?
Or, there might be enough demand from APM UAVs wanting an all in one RTK flight controller to offer a Navio2 with a M8T?
