Nvidia IsaacSim rosbridge__no message published on advertized rostopic

[amanuel.ergogo]

I Tried to Publish ROS messages from builtin ROS examples in Isaac sim. using rostopic list I see advertised topics but not receiving a messages using rostopic echo /joint_states and rostopic hz /joint_state shows me no message received.
I have tried both in IsaacSim 2022.1.1 and 2021.2.1
ROS_MASTER is a local host which runs Isaac Sim, ROS network setup works and i have background in ros.

Can you please mention the name of the examples which you are trying to run with host specifications and a log file?

@amanuel.ergogo , can you please provide the name of the examples as requested in previous message?
Also, did you try with the latest Isaac Sim version (Isaac Sim 2022.2.0)?

@rthaker This issue was related to ros network setup not really to IsaacSim. It’s solved. more discussion is here

How to Change ROS_MASTER_URI of OmniIsaacRosBridge

I tried to change the ROS_MASTER_URI of OmniIsaacRosBridge in omni.isaac.ros_bridge.scripts.extension file so that i can connect to different host rather than the one running isaac sim(2022.2.0/2022.1.1) but isaacSim is overriding my choice by just taking the local host name. as shown here [image] while the master uri is [master_uri] It works well on a local machine running isaacSim and but can not connect to other host running ros master node.

thanks,
