I am having trouble communicating with my MATLAB ROS ndoe. I am deploying my node into my VM and trying to see the topic.

While I am able to see the topics from the MATLAB node, I cannnot send any messages to the node.

I think that it is a problem with the ROS IP but not sure how it should be set.

The VM bashRC:

export SVGA_VGPU10=0
export ROS_IP=$(hostname -I | tr -d [:blank:])
export ROS_MASTER_URI=http://$ROS_IP:11311

my local machine bashrc

export ROS_IP=192.168.137.129
export ROS_MASTER_URI=http://192.168.137.129:11311/

What is the proper way of setting the IP address.
