I have successfully been using an Raspberry Pi to communicate with a pixhawk1 via serial with
master = mavutil.mavlink_connection("/dev/serial0", baud=921600)
However I am now migrating to a wireless telemetry connection and the antennae for the RPi is USB (The antennae for the pixhawk is connected to telem1 as were the serial wires before). I am having trouble initiating a connection in pymavlink. I thought
master = mavutil.mavlink_connection("/dev/ttyUSB0", baud=921600) would do the trick but its not working. Other ideas?
