Are you using the standard configuration of PC + RPi3/4 for your TB3? Perhaps instead of looking at fixing this issue, would you be interested in another approach? Recently ROBOTIS releases a new TB3 branch (for beta testers) that uses DOCKER + ROS2 that combines the PC and SBC functionalities into a single computing platform. So far I tested this branch on a Burger and with a Jetson Orin Nano and also on an RPi5 (by itself). I have tested only “teleop” via the keyboard, but all components seemed to be working OK. If you are interested, a detailed post is available here:
I do not have an RPi3 or RPi4 anymore so I don’t know if DOCKER + ROS2 would work on them.
