S500 does not take off with offboad_control from px4_ros_com running on jetson nan

Hi Prakit,
Thank you for your answer.
I’m using a playstation controler as i don’t have an RC. I assigned the offboard mode to some button but when pushing it , the mode doesn’t switch. The same when changing manually in QGC. Is there something in my configuration that prevent to switch to offboard mode? Does the joystick instead of the RC matter?

I’m using v1.13 because of that post Help with uXRCE-DDS to serial connection - Pixhawk 6c saying thats it’s not working^^. You’re using v1.14? which companion computer do you use? how it is link to the autopilot?

Yes i’m using the offboard_control.cpp example in the ros2 package px4_ros_com.
