Debugging LiDAR dropouts: IP fragment reassembly failures fixed via CycloneDDS tuning
this_is_surabhi · x · 2026-09-07
A robotics developer documents diagnosing why LiDAR, stereo camera, and 200 Hz IMU data failed to cross a 1GbE link between two ROS2 machines. Root cause: bad IP fragment reassembly failures on large, fragmented messages. The fix was tuning the Eclipse CycloneDDS config — a directly reusable lesson for multi-machine robot setups.
