Could you please share some info about how to get correct ring value from your ROS2 package?

hi @JunLFang have you solved this problem? I also encounter the same question.

I contacted Hesai's technical support and the issue has been resolved. For my computer, the main problem was a CUDA compilation bug. By commenting out the corresponding CUDA sections in the CMakeLists.txt file, the ring values are now output correctly, as shown in the picture.
