Sending rc_channels_override to px4

Brian_Duvall · February 11, 2020, 5:21am

Hello all,
I am trying to use rc_channel_override. I am using python with mavutil.
This is my code to send my message:
while(True):
master.mav.rc_channels_override_send(0, 0, 2000, 1500, 1500, 1500, 1500, 1500, 1500, 1500)
time.sleep(0.02)
print(“Sent Message”)

where master is (the_connection) show in documentation. I have the plane flying HIL with xplane 10 in stab. I also tried manual but I got no response when I send this message. I see rc_channel_overide is in the PX4 mavlink_receiver.cpp file so I think this should be working.

PX4/Firmware/blob/master/src/modules/mavlink/mavlink_receiver.cpp#L1864


		 */
		return (_mom_switch_pos[sw] * 1000) / (state_count - 1) + 1000;


	} else {
		/* return the current state */
		return on * 1000 + 1000;
	}
}


void
MavlinkReceiver::handle_message_rc_channels_override(mavlink_message_t *msg)
{
	mavlink_rc_channels_override_t man;
	mavlink_msg_rc_channels_override_decode(msg, &man);


	// Check target
	if (man.target_system != 0 && man.target_system != _mavlink->get_system_id()) {
		return;
	}


	// fill uORB message

any ideas?
