How to connect Matlab with ROS over Network?

Hello Matlab-Users,

I have a big problem setting up a connection between Matlab and ROS!

my situation:

• PC 1: Ubuntu 16.04 / Ros kinetic / roscore running
• PC 2: Windows 10 / Matlab 2017b / Robotics System Toolbox
• Self-made simple publisher and subscriber system to check connectivity
• set environment variables (ROS_HOSTNAME_URI/ROS_IP) on Ubuntu machine
• Connection is set up -> rosnode list shows all active nodes on both PCs
• rostopic list also shows the active topics (doesn't matter on which PC Nodes are publishing on/subscribing to)
• publishing data from a node running on Ubuntu machine and subscribing to the same topic in Matlab works fine
• other way round does not work / you can echo the topic, but there is never data coming

I've already read many posts dealing with the same issue, but there was nothing that really worked in my case!

I really hope that you can give me some useful advice! It is very important for me to have success in setting up the connection!

Thanks a lot for your help!!!
