Getting error while setting offboard

Im using pixhawk 2.4.8 and jetson xavier nx. i’m doing some autonomous flight stuff and while setting my drone to offboard im getting some sort of error saying MODE: Unknown mode: OFFBOARD
while giving command rosrun mavros mavsys mode -c OFFBOARD
Please help!

OFFBOARD mode does not exist in ArduCopter 4.1.1, you need to use guided mode instead.

rosrun mavros mavsys mode -c GUIDED

should work a lot better :slight_smile:

Can’t use guided mode because i’m not using gps…im using algo’s for localization…Is there any option to create a custom mode?? of offboard

Okay! In which ARDUCOPTER version does OFFBOARD mode exists??

Offboard mode does not exist in any version of Arducopter. You have to switch to the PX4 firmware to use it.

Can you tell me which particular version is there in which offboard mode is available?

For further questions regarding the PX4 firmware, I suggest you go to It has been years since I last tried PX4 firmware, so my knowledge will most likely be outdated.

Or you can keep arducopter and use GUIDED_NOGPS instead :stuck_out_tongue:
