I am tracking a bug where the /LaserScan messages have incorrect (off by a factor of 10^6) values for timeincrement and scantime. I find that there are two, different, packages that seem to support ydlidar X4 on ROS:

• https://github.com/YDLIDAR
• https://github.com/EAIBOT/ydlidar

Does anyone know which is which and why?
