XRCE-DDS/ROS 2 over USB between Cube Orange and Jetson Orin NX / Raspberry Pi 4?

PX4 Autopilot
1

I’m using a Cube Orange running PX4. TELEM1 and TELEM2 are already occupied. I want to connect a companion computer (D115W Jetson Orin NX or Raspberry Pi 4) via USB and use XRCE-DDS with ROS 2 (uXRCE-DDS client on the Flight Controller, agent on the companion).

Is running the XRCE-DDS link over the Cube’s USB supported instead of the TELEM UARTs? If yes, which device/port and parameters should I use (e.g., which /dev/tty*, required PX4 params, baud, etc.)? Any known pitfalls or examples are appreciated. Thank you!

What about using the GPS2 port? Using USB in flight is generally not recommended.

Thank you very much for your response. Could you please take a look at the topi I just opened, which I consider quite important? https://discuss.px4.io/t/seeking-insight-on-weird-fixed-wing-behavior-during-autonomous-takeoff/47141

I don’t appreciate that sort of “while I have you, also help me over here."

I go through the forum on my own schedule. If you want help, be patient, and if it’s urgent, consider paid support (Consultants - PX4 Autopilot or github sponsoring to get attention).

Of course, I didn’t mean anything like that in the first place. As a matter of fact, I didn’t send a private message to your phone so I’m still tyin to reach out through the forum. I just meant to say when you have time to check here, could you please take a look? Unfortunately, I haven’t seen anyone else from the “dev team” active on the forum except for you, which is why I addressed it this way. I apologize if I was misunderstood. In any case, I truly appreciate your efforts and am grateful to you.
