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.

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 image

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

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
