Question about FCI connection and timeout

[vegetableclean]

Thank you for sharing your code! I have tested it both in simulation and on the physical Franka arm (Franka 3). I am currently using Ubuntu 24, so I am running everything through Docker and so that I can use ROS2 humble.

The simulation works perfectly, and all the example demos run smoothly. However, when I switch to the real robot, even though the FCI is activated, I constantly encounter timeouts or warnings indicating that FCI is not installed. Interestingly, the robot operates normally when using Franka Desk, so I am unsure what exactly is causing the issue. I have tried several approaches but still no success.

Do you have any suggestions or guidance on this problem? Thank you very much!

Best regards

maybe I can give some help, if the problem still unsolved，the information is too little

Hi @vegetableclean ,
a timeout usually points a bit towards network problem. Are you sure that your network card/switch/... is up to the task? What do you get if you ping the robot?

Cheers,
Andreas
