Cannot change flight mode on Cube Blue with Ardupilot via MAVROS2

[wntun]

---

Issue details

Hi, I use the mavros on the jetson and connect the FC via serial. I can see the values coming from the FC. But, I cannot change the flight mode nor arm/disarm. I can do it all on the mission planner.
Any suggestions or solutions, please?

I tried with Pixhawk6C. It has no problems. I don't know what to do with the Cube Blue.

[vooon]

Hello,

Have you tried other commands? I do not see firmware version report in the log, so i suspect that there may be problem on OBC -> FCU path.
Have you checked that OBC Tx -> FC Rx have no issues?

[wntun]

Hi, @vooon .. I don't think there is problems in the cable. I used the same cable for the Pixhawk6C, and it has no issues in sending/receiving data.
Right now, for the Cube Blue, the USB line works.

[vooon]

I'm not sure, but maybe the port you use configured in telemetry-out mode only? Don't remember exact params and values. But i remember that there were different modes of operation for mavlink app on the PX4 side.

[wntun]

@vooon .. hi, thanks for the suggestions. I'm using the arducopter. I modified the sr2_xxx variables, according to the sr0_xxx variables. Before that, I can't even see the incoming data from the FC. I can't find anything else yet. Please let me know if you remember anything.
