How to inspect mavlink message sent to the drone?

[Runze DING]

Hi there,

I have my bebop2 connected via wifi and send message using udp. For now, I want to use motion capture system to send its position and altitude in a mavlink message. But I don't know whether the drone received it. If there any feed back from the drone? Or any way to spy on mavlink traffic on wifi?

Thanks.

Whether there is feedback or not from the drone depends on what message you send it. If you just want to test the communications, then try send a mavlink command, because that responds with an ACK.

I don't know if you can spy on the wifi, but you can certainly spy on your computer interfaces using wireshark or similar (assuming you're sending from a computer).
