YDLidar X2 with the same problem.
Same any solutions? Tried even using the windows driver to check if the sensor is ok but if says failed to start on cloud viewer
Hello ! Same error here, multiple YDlidar G2 bought and 99% of the time I run into this kind of error (either [No error] or [Laser failure]). Only twice could I have a running lidar process, (but without scans...)
Used on Ubuntu 20.04, under ROS2 Foxy, after SDK installation.
Errors encountered using SDK's process : ydlidar_test
Errors encountered using Driver's cmd : ros2 launch ydlidar_ros2_driver ydlidar_launch.py

If someone happens to have a solution, I would be really grateful :-)
Hello
I met same error on YDLiDAR x4 @RPi4 Ubuntu20.04, but it was solved.
I re-download "YDLiDARx4 SDK" from "https://www.ydlidar.com/service_support.html" (Not this git SDK that is little bit different with YDLiDARx4SDK)
And re-build on same flow as below. cd sdk/build cmake .. make sudo make install
And then, run "build/ydlidar_test" on "Baudrate: 128000"
It work on my environment for now.
I'm glad if this help. Have a good LiDAR life !!
Thank you

Pls choice 1 on baundrate not 0. And did you set access rights for USB ?
I am having the same problem with G2 model, I tried both with git and website SDK but it persists.
Try method by Nhe-Fix It works
I am having the same problem with G2 model, I tried both with git and website SDK but it persists.
Try method by Nhe-Fix It works
Nhe-Fix also asks for the solution, which method Nhe-Fix recommends? I would be glad if you clarify 🙏🏻
Sorry not nhe fix Happy dev one Try different baudrates One will definitely work
Then there is some file where we need to change the baudrate for lidar
when i try to start my lidar with ydlidar_test.py, i get :

lidar start spinning but after some seconds it die.
