I am using this with static address assigned (192.168.1.2) it's look like you are using it with some kind of "automatic address".

That "automatic address" looks suspiciously like what you get when a computer is configured to use DHCP but there is no DHCP server available, so it defaults to something like that. Is the laser configured to use DHCP to get it's address but there are no DHCP servers available on the same LAN as it?

Are you using latest version from : https://github.com/RCPRG-ros-pkg/RCPRG_laser_drivers  ?

After modifier network connection, I can ping the address of the laser scanner.

 

tienthanh@tienthanh-pc:~$ ping 169.254.193.164

But I still got the error when run LMS100

Hi,

Thanks, I got ID address of LMS111 from SOPAS software is 169.254.193.164. But I can't ping it after connect it to my PC

Of course, it can not connect to ROS

tienthanh@tienthanh-pc:~$ rosrun LMS1xx LMS100

I don't think there is any problem with a laser scanner (it works with Labview in Window). And I have no idea why it not works in ROS

Cheers,

you have to use the IP of the LMS100, not the one of your host ;)
