Is there anyone who has gotten smart port to work on a matek f405 wing? I have the yaapu script running on my X9D and it says no telemetry. I also do not get the telemetry by discovering sensors. I’m using uart 6 with a yaapu wire connecting to the sport on an x8r. In ardupilot I’m using serial protocol 10 and serial option 7. If anyone has this working I would love to know how you have it wired and what ardupilot parameters you are using.
Normal s.port is an inverted protocol (high voltage means logical zero, which is opposite to what the flight controller expects), and the F405 chip can’t invert arbitrary ports the way the F7/H7 processors can.
