I’m trying to upload waypoints for autonomous flight. So lets say I program 4 waypoints on mission planner and I want to get those on to the autopilot. I can do this if I plug the USB directly into my APM 2.6 board and it works great, but if I try to upload via my 915Mhz radios it times out. I’ve also noticed downloading certain parameters via my 3DR radios is timing out as well. One parameter i can not download is the flight modes assigned to a channel on my RC TX.
