Hello @FrGe2016 , I have already debugged and rewritten some code which you can see in pull request #23 (this is just a draft). It worked on my Khadas vim4, but I have not tested it on my Raspberry Pi 3/4 or my Ubuntu virtual machine.
Thanks, I will check it out.

Thanks it is compiling But i have a new issue. The lidar is stopping rapidly after the first tests. I have adjusted the yaml file for the X4 model I have pretty much the same result testing only the SDK. Using the same rpi4 with ubuntu 20 and ROS1 is working well?

@FrGe2016 I don't know why but I figured out that the yaml parameters did not work, you must change the parameters directly in the source code, I explain it in the README, then change the parameters in the source code and re-use the colcon build command in the same directory like you did before a step forward to recompile the code.
The SDK did not work for me too
I have made a few additional tests
From the ydlidar site i have downlodad the SDK for the X4. Now the sdk is alone is working. But with the ros 2 driver the scan is stopping after around 10 seconds. I will look at your read me to modify the parameters and let you know
The sdk never worked for me, but after some troubleshooting changing directly node->get_parameter("/dev/ttyUSB0", str_optvalue);
with the right parameters work for me. If what I guess is correct when we type ros2 launch ydlidar_ros2_driver ydlidar_launch.py
we may add the parameters after like -p port dev/ttyUSB0 -p bauderate 115200
for example but with my version that no longer work anymore.
Hello @FrGe2016, do you succeed ?
Same issue on rockpi
workaround here https://github.com/YDLIDAR/ydlidar_ros2_driver/issues/21 worked for me! ...
Many build errors when i build the package I am not strong at cpp so here is are typical exemples ( there is many so much of them that i can not copy them all)
