Hello world!
I would like to fly to some waypoints using MAVROS.
Therefore I dispatch MAV_CMD_DO_REPOSITION
commands to the /mavros/cmd/command
service.
This works as long as QGroundControl is running. Since I really don’t use it for anything though, I would like my script to work without a running QGC instance as well.
But it doesn’t: arming and takeoff are possible, but it lands right afterwards stating WARN [commander_tests] Failsafe enabled: no datalink
.
What does QGC do to make it work, i.e. what do I have to do to avoid having to run QGC?
Thank you!
Appendix:
- I’m using SITL gazebo simulation
-
rostopic echo /diagnostics
states FCU connection is present - the only difference in the ulogs is the
telemetry_status
topic showing up when running QGC, but I don’t really know what that means… - MAVROS offboard control works without QGC
