Good Afternoon,

I am on Raspberry Pi4, UBUNTU FOCAL, ROS Noetic, and trying to run

roslaunch rplidar_ros view_rplidar.launch

and I get the Error below Please advise on how to get past this?

started core service [/rosout]
process[rplidarNode-2]: started with pid [6604]
process[rviz-3]: started with pid [6605]
[ INFO] [1591737781.112395048]: RPLIDAR running on ROS package rplidar_ros. SDK Version:1.12.0
[ERROR] [1591737783.970103291]: Error, operation time out. RESULT_OPERATION_TIMEOUT!

when I check my serial connection via :

ls -l /dev|grep ttyUSB

I got:

crwxrwxrwx  1 root   dialout 188,   0 Jun  9 21:34 ttyUSB0

As you can see I also adjusted permissions on ttyUSB0.

You'll want to contact Slamtec about this. See their issue tracker. It would also seem there is already a similar issue on that tracker: Slamtec/rplidar_ros#5.
