Offboard mode in SITL

PX4 Autopilot
1

Hi!
I have been having trouble with the offboard mode in PX4. I have been trying to use it via SITL with the iris model and have not been successful. I tried two approaches:

  1. I have tried to implement it via the MAVSDK python example ‘offboard_position_ned.py’.
  2. I have tried to carry it out following the offboard control example in https://docs.px4.io/master/en/ros/ros2_offboard_control.html.
    Both implementations lead me to the same error that triggers the failsafe.

Is there something wrong with the offboard mode? Am I doing something incorrectly? Has anyone experienced the same issue?

Thanks in advance!

Hello @Xun;

I have been struggling with the same problem for weeks, but I always end up with that error. I have tried recently ROS 2 as well (see my last topic) but I also end up with the same message. @LorenzMeier

Are the parameters NAV_DLL_ACT = 0, NAV_RCL_ACT = 0 and COM_RCL_EXCEPT = 4?

Thank you so much! That actually solved the issue. I was able to fly the offboard example in C++ for the iris model.
One additional comment, have you ever tried to use the offboard mode while flying visual without gps?

Why they should be set in this way?
