Originally, I posted the entry here, but I think this place is more appropriate.
When I power my turtlebot3 robot, the lidar is spinning by default. But when I run ros2 launch turtlebot3_bringup robot.launch.py command, my lidar stops spinning and not receiving any scan values in the ros2 topic echo /scan.
In the log file I see:
[ld08_driver-2] /dev/ttyUSB0 CP2102 USB to UART Bridge Controller
[ld08driver-2] FOUND LiDAR
[ld08driver-2] LiDAR started successfully
but lidar not spinning and not send any data in topic /scan.
I installed the SBC base on https://emanual.robotis.com/docs/en/platform/turtlebot3/sbc_setup/#sbc-setup manual "FOXY" tabs
I met this problem before and tried replacing the lidar launch, view files. And it could run.
Check the files in /opt/ros/foxy/share/hls_lfcd_lds_driver/launch and /opt/ros/foxy/share/hls_lfcd_lds_driver/rviz/
