I am currently trying to setup a Gazebo and Simulink Co Simulation to design algorithms for robot motion control.
I have established the Gazebo Plugin connection. At least if I add the Gazebo Pacer to my Simulink model and test the connection it returns a success message. Now I am trying to subscribe and publish the specific ROS messages to get the state of the robot. When I am trying to subscribe to /joint_states and select Position via Bus Selector I get a 128 elements long array (as expected) but all are zeros. Further when I try to echo this topic either in Matlab Comand Window or in a Linux Shell on my Virtual Machine I cannot get the topic. It said in the Linux Shell that no messages are available. But when I just start the Gazebo simulation without the matlab pacer I can echo the topic successfuly in a Linux Shell. So it seems the Gazebo Pacer somehow is elated to this problem.
Can someone help me solve this problem?

You might need to update plugin from VM. Use packageGazeboPlugin and copy-build plugin on VM.
