I’m using the HolyBro Kakute H7 Mini. I’m trying to connect a 3DR telemetry radio. I have it connected to UART 4. In Mission Planner I set serial4 to 2, which should be MAVLink, but I’m unable to connect. Just in case I wired TX and RX wrong I also reversed the wiring on that, with the same results. I have the baud rate set correctly (57600) and I am able to connect to a Cube autopilot using the same radio. Any ideas what I’m doing wrong?
Solution: I changed the baud rate of serial4 to 57600 and it worked!
