You have a problem somewhere on computer Tx -- FCU Rx connection.

Have you had apm planner running, while trying to start mavros? From logs i see that message flow from autopilot to mavros works, but nothing gets to the autopilot from...

Since MAVLink 1.0 works, you may try to set `~fcu_protocol` = `v1.0`. See: https://github.com/mavlink/mavros/blob/master/mavros/src/lib/mavros.cpp#L55 But i recommend to check firmware parameters and change to MAVLink 2.0. Also to eliminate possible...

What is the difference to [rallypoint](https://github.com/mavlink/mavros/blob/master/mavros/src/plugins/rallypoint.cpp) plugin?

@amilcarlucas but does it really needed? I tested ros2 port of rallypoint on APM simulator, and it works good.

Do you sure of that double `/mavros/mavros`? Could you please list nodes? Btw sometimes i sees problems with topics/services, but don't know why they are happening. Maybe it's on DDS...

@dayjaby that's looks like there some trouble with sub-nodes of plugins because usual path would look like `///`, e.g. `/mavros/global_position/global` -> UAS's name is `mavros`, Plugin name is `global_position`, and...

@dayjaby here is example from by build: ``` root@c169f39972ff:/# ros2 node list /mavros /mavros/actuator_control /mavros/adsb /mavros/altitude /mavros/cmd /mavros/ftp /mavros/geofence /mavros/global_position /mavros/home_position /mavros/imu /mavros/landing_target /mavros/local_position /mavros/manual_control /mavros/mission /mavros/param /mavros/rallypoint /mavros/rc /mavros/setpoint_accel...

@dayjaby galactic, but foxy should be exactly same.
