hello, I had a similar problem of not working the pairing of radios, I noticed that in the ‘’ BASE MODE ‘’ regardless of which input and output of correction should be UART make it workable the communication part.
on the other hand that I ask your help to try to put my rtk emlid reach kit to work, the radio is as I said earlier GROUND USB and ROVER PINOS, that is, UART, they seem to be communicating, but the gray bars do not appear . clicking on the link you can see my questioning I can not use the 3dr through the USB / OTG port can help me see what I’m doing wrong…
