Hi @MartyG-RealSense , I hope you are doing well. i got stuck in this tried many possible ways you have mentioned in other issues too. but it doesnt work for me. Please help.

Issue Description

I have installed librealsense from source and then ros wrapper from source too. and when i run realsense-viewer i get the output as stereo-module, rgb and other too. I have tried installing from libuvc but still it doesnt work. But when i run or launch file from ros2 it shows error as no realsense device found. Problem: Distro [realsense2_camera_node-1] 01/01 10:45:33,664 WARNING [281472493676768] (d400-factory.cpp:1195) DS5 group_devices is empty.

Hi @amaraashishmahatokushwaha I notice in the information at the top of this page that you are using librealsense SDK version 2.55.1, so the correct ROS wrapper version to match to it is 4.55.1. You have wrapper 4.51.1 installed though, which is designed for the earlier librealsense version 2.51.1.

As you installed the 4.51.1 ROS wrapper from source code, please completely delete the /ros2_ws/src/ catkin workspace folder to uninstall the 4.51.1 wrapper and then install the 4.55.1 wrapper. You will not need to install librealsense again, only the wrapper.

Hi @MartyG-RealSense , Thank you for your observation regarding version and reply. Actually that version compatibility is required to run on NVIDIA Isaac ros, you can go through NVIDIA Isaac ROS Real-sense Setup Guide. I have shifted to Nvidia isaac ros . I am currently running slam from isaac ros with the camera. And its working fine. If i need to run normally i'll remember your points to go ahead. Thank you again.
