I have a question on setting up FrSky RX4R with Matek F405 Wing. Initially I had some trouble getting the Rx to talk to the Matek board, but I managed to get it working by plugging in the Sbus out from the Rx to the R2 pin on the Matek board. I discovered this by mistake, actually, and it’s very odd since it simply won’t work with the Rx Sbus out connected to the Sbus pin on the Matek board. Any thoughts on why this might be?
Not sure if I’m happy to fly like this, and I occasionally get “No RC Receiver” error warning in Mission Planner.
Any thoughts on why the Rx won’t work when connected to the Sbus port on the Matek board?
