[driver][socket] Rslidar poll() timeout Ubuntu 18.04 ROS Melodic #31

I know that you only explicitly support ubuntu 14.04 and 16.04, but I have been trying to set up the rs_lidar_16 on 18.04 but get this warning when running :

roslaunch rslidar_pointcloud rs_lidar_16.launch

Is there any solutions for this issue?

I had the some problem. You need to check if you can ping your RS-LiDAR (IP: 192.168.1.200). It can be that you have not you Ethernet port to the specified IP-address. Change the IP-address of the Ethernet port you have your sensor connected on to the static IP 192.168.1.102.

After that check that it is the above IP-address and try to ping you RS-LiDAR again. If you get a result/ping back you can try the roslaunch again.

I hope my explication is understandable and good luck.

I also encountered this problem. I set the IP correctly and can ping the device, but the following error still occurs.

anyone got this error fixed? we can ping the sensor but still timeouts

EDIT: My fault. Somebody already changed the lidars "Computer IP". Had to change my PCs IP corresponding to that change.

I met the same problem on melodic too. I set the correct ip, but i couldn't ping the lidar.

Did you change the MSOP port or DIFOP port? You can run a Wireshark, and check if your setting is right. If you are new to this driver, you can use our new driver, which support melodic and ROS2 formally.
