I have a fixed wing vehicle running PX4 1.14 on a CubeOrange+, with a ReComputer J3010 (jetson nano) companion computer running MAVSDK. I am trying to send servo position commands from the companion computer to directly control my control surfaces ahead of the flight controller for system ID work.
Reading the docs, it seems like the best way to go about this is a function called offboard.set_actuator_control, but it doesn’t seem to be working. For one, sending the offboard.set_actuator_control messages doesn’t allow offboard mode to be activated when armed (I get the ‘No offboard signal’ error). When I send attitude rate command messages in addition to the actuator control messages, I’m able to get into offboard mode, but it still seems like the actuator commands aren’t doing anything, because my servos don’t move.
If anyone knows whether or not offboard.set_actuator_control is still supported by 1.14, I’d love to know. Or if anyone has an idea for an alternative method to send actuator commands from a companion computer, I’ll give those a try too. Thanks.
