Hello everyone,

I have installed Isaac Sim on Windows 11 and am trying to connect it with a ROS2 Humble distribution installed in WSL2. According to NVIDIA’s installation guide, this integration should be possible (refer to the guide here: NVIDIA Isaac Sim Installation Guide). However, despite following the guide meticulously, the topics are not appearing as expected.

I have ensured that the correct ports are open between Windows and WSL2, but I’m still facing issues. One area of uncertainty is how to set the environment variable FASTRTPS_DEFAULT_PROFILES_FILE within the “Extra Args” field on Windows 11.

I have verified that I can successfully ping both ways between Windows and WSL2 so i dont think networking is the issue.

If anyone has a comprehensive guide or can provide step-by-step instructions on how to achieve this setup, I would greatly appreciate your help.

Thank you!

Hey @exb Welcome to the community!
When you run the Isaac Sim App Selector, it has a field “Extra Args” where you can set the environment variable FASTRTPS_DEFAULT_PROFILES_FILE

Yes but as i am working in windows do i need to set this? And what would be the exact command be? I feel like i have tried both with “export” as i would in ubuntu and with “set” as i would in windows. Still no topics showing up.

Did you enable ros2_bridge extension from the Isaac Sim?

It would be more helpful if you can share what you have done step by step and if there is any error you have seen during set up
