Hi! I was going through the tutorial and everything was working as described until the last step.

After launching the demo, I switched to offboard mode in QGC, but nothing happened after waiting for a few seconds. The visualizer and control nodes are running and RViz opened, but nothing is getting published to /fmu/in/trajectory_setpoint.

Thank you!

My mistake was using PX4-Autopilot and px4_msgs on different versions. Here is what I found:

  • PX4-Autopilot in release/1.14 and px4_msgs in main produces the problem described above (obvious in hindsight)
  • PX4-Autopilot in release/1.14 and px4_msgs in release/1.14 makes it impossible to switch to offboard mode (no offboard signal)
  • PX4-Autopilot in main and px4_msgs in main works

Hello! @felix-muller have you tried in a companion like Jetson? I found in Discord community that there are problems with the communication with the Autopilot using the main branch.

I was also wondering @Jaeyoung-Lim if you always use micro-ROS, since I could not find more info about it in the PX4 documentation.

Thanks!

@Jimi1811 As far as I know I dont think there is a known issue with using micro-ros with the fmu between the jetson.

I used micro-ros and it works
