ArduCopter MAV Commands on Arduino

ArduCopter
1

Hi. I’m very new to this and would appreciate any help.

If I wanted to send a MAVLink message to a Pixhawk4 to start a mission (MAV_CMD_MISSION_START/MAV_CMD_NAV_LAND) can I do this from an Arduino? I haven’t seen it on the MAVLink libraries on GitHub and on the website it says that these commands are supported by ArduPilot copter. Does this just mean that I need to install the ArduPilot software on the Pixhawk in order to be able to use the commands? Would I need to create custom messages from the Arduino or is it incompatible?

Thank you.

I eventually plan to do something similar. I can’t personally help you but have you seen this thread? MAVLink and Arduino: step by step. I have been following it for some time and looks very helpful.

Hello! Yes I have, but it looks to me that it mainly involves sending Heartbeat messages to the Pixhawk and requesting data from the Pixhawk. Thank you though. I’ll keep looking.

By the way, I can answer one of your basic questions. You have to have a variant of ArduPilot installed on the PixHawk hardware. ArduCopter is a variant of ArduPilot. If you have that installed, you have what you need as far as software on the PixHawk.

Understood, thanks for your help!
