Stop motor service doesn't work

[hello-chintan]

I am running the sllidar_ros node for RPlidar A1 on my robot that runs on Ubuntu 20.04 with ROS 2 Galactic. The node runs fine but after termination, the lidar motor keeps spinning. The stop_motor service has no effect. Upon investigating, I found that this was not a problem until release 1.7.0 in ROS 1, however, the issue has crept into the ROS 2 package as well thereafter. Could you point to a fix for this?

Hi, I am running in the same problem. I am using rplidar C1 for my project and am unable to control the LiDAR's motor via ROS services, have you found any solution for this problem? Any help would be appreciated. Thanking in anticipation.
