3 years ago Hard to say if this is a hardware or software issue. I am guessing you are connecting directly from ethernet to ethernet via a rj14 cable. So there are multiple points of failure. You need to check if both ports and the cable are working before you start looking at software and drivers. The first thing I would do is to plug both the Pi and the SICK into a router and check to see if the hardware is all working.

I'm using the most recent image this ubiquity-xenial-lxde raspberry image (v2020-11-07) https://downloads.ubiquityrobotics.com/pi.html to use a Pioneer 3DX + SICK LMS100 LiDAR, specifically using the ROSARIA http://wiki.ros.org/ROSARIA/ package for the robot and either LMS1xx http://wiki.ros.org/LMS1xx package or sick_scan http://wiki.ros.org/sick_scan package for the laser scanner.
However, despite following usual process [1] https://answers.ros.org/question/207220/connecting-a-sick-laserscanner-via-ethernet/ [2] https://answers.ros.org/question/207220/connecting-a-sick-laserscanner-via-ethernet/ to check the laser's static IP, when I try to open a TCP connection it gets refused every single time.
Is it a problem with my process? I believe it could be a problem with the image, and if not, something that should be documented for clarity. Can anyone help?
