2020-03-31 11:06:29 -0500 marked best answer Setting parameters just work through rqt_reconfigure, not rosparam

Hello ROS developers,

I am currently using this depthimage_to_laserscan package. I wanted to change some parameters (for instance range_min). When I do it in rqt_reconfigure, everything is fine: the parameter changes, I can see it in rviz. But when I do it with rosparam set, rosparam get verifies that it is set, but neither the value changes in rviz nor in rqt_reconfigure. So why can I change the parameter just through rqt_reconfigure and not the command-line tool rosparam?

I am using Ubuntu 16.04 LTS with ROS kinetic.

I would appreciate every help, thanks in advance guys!

Best regards cheesee61
