I used this guide here: isaacsim-app-template/templates/apps/isaacsim at main · isaac-sim/isaacsim-app-template · GitHub for my Isaac Sim download. I am using the ROS launch option yet when I go into the app I get an error that ROS2 Bridge Startup Failed with no other errors accompying it. I have ROS2 downloaded and have followed the steps here: ROS and ROS 2 Installation — Isaac Sim Documentation . On my normal Isaac sim app launch it works but on this template app (using ros launch) it does not work.
To help us better understand and diagnose the problem, could you please provide the complete log output from the terminal when you attempt to launch the app? This will give us more context regarding what might be causing the “ROS2 Bridge Startup Failed” error.
I am just realizing that before my error, I am getting this “[58.396s] To use the internal libraries included with the extension please set:
RMW_IMPLEMENTATION=rmw_fastrtps_cpp
PATH=%PATH%;c:/users/documents/custom_app/isaacsim-app-template/_build/windows-x86_64/release/extscache/isaacsim.ros2.bridge-4.1.15+106.5.0.wx64/humble/lib
Before starting Isaac Sim” Which does in fact tell me what is wrong. However I do not exactly understand what to do to fix this. Thank you.
I also want to clarify that this is a custom app not just the regular Isaac Sim. I am using the ROS Launch option when booting the app.
Have you tried setting the path and RMW_IMPLEMENTATION in your ~/.bashrc file and then source it?
how do I do that on windows with the isaac sim custom template? I have it set properly on my regular isaac sim download but I can’t seem to get this one to work.
Sorry, my bad. I forgot this topic is on Windows.
I haven’t had a chance to try on IsaacSim App Template. However, could you refer to my previous experience in Troubleshooting: Missing ROS2 Topics in Isaac Sim on Windows 11 with WSL - #16 by VickNV?
thank you, i will try that and get back to you.
