Hello, I am using the hesai pandar40p with this driver for ros1. I am using ubuntu 20.04 with ros noetic

When I try and launch the node i get the following error:

Hi hazcoper，

Could be system related issue, could you please try the HesaiLidar_ROS_2.0 project? it supports ubuntu20.04 better, it supports most ROS1 and ROS2 versions.

Thanks,
Fred

Okay, I will look into that
Could you tell me what are the improvements in HesaiLidar_ROS_2.0 and the new sdk?
