I have a Pixhawk and I'm trying to connect an Intel Edison SOC to it using Mavlink. If I connect using a 3DR radio, the connection works fine. If I hardwire the connection (serial port on Edison to Telem port on Pixhawk), I can read the telemetry data from the Pixhawk, but the Pixhawk seems to ignore any commands I send to it.
Any ideas as to why the Pixhawk is responding differently to a radio connection vs. a hardwired connection?
