I am using px4, pixhawk interfaced with ROS kinetic and mavros on RPI3. I need to send a custom mavlink message from mavros to ground control software (QGC). The only communication link I have is a telemetry connected to TELEM1 port on the pixhawk.
Can I route my message from mavros <–> pixhawk <–>telemetry <–> QGC?. Please help.
