I have successfully connected a DJI Matrice 4 to FreeBSD via USB.
FreeBSD detects the aircraft as a USB network interface: ue0
The interface can be configured using dhclient: dhclient ue0
After connecting, FreeBSD creates the USB network interface and communication with the aircraft's network side becomes possible.
In my setup, the FreeBSD side uses the 192.168.42.x network, with communication taking place over ue0.
This is only the first step, but it confirms that a DJI Matrice 4 can establish a USB network connection with FreeBSD without requiring a Windows host.
I am currently investigating the communication further and will post more technical details as the work progresses.
Would you be interested in a utility for working with a drone?
