Hi im currently running the sicktoolbox_wrapper package for the LMS200 for scanning purpose I have two LMS200 and would like to use them at the same time I know the connecting port which are ttyUSB0 and ttyUSB1

lets say im running in port ttyUSB0 when i execute the command of

rosparam set /sicklms/port /dev/ttyUSB1 rosrun sicktoolbox_wrapper sicklms

the old one is killed because of

[new node registered with the same name]

is there any possible way to change the node name before executing it? or is it possible to copy and paste then reinstall the same package with a different and publishing a different node name?

I am trying rosparam set but have not found a clue yet plx help

See this answer, it shows how to set the node name both from the command line and from launch files.

i just found that if i do rosrun sicktoolbox_wrapper sicklms __name:=sicklms2 it says attempting to open devic @ /dev/lms200 which is a path that i never told the computer to do

This is probably the default value. You will need to set the parameter `rosparam set /sicklms2/port /dev/ttyUSB1` when you run `rosrun sicktoolbox_wrapper sicklms __name:=sicklms2`. It is probably best if you create a launch file for your nodes.
