ROS2 Simulink Toolbox not subscribing to Python Publisher

Hello everyone!

I am working on a project, and for that, I am using ROS2 Foxy on Windows. My aim is to publish commands using a Python Script that I have created on ROS Network, and then, that command will be subscribed by the same topic in Simulink. I am using MATLAB R2022a. So, my publisher is working perfectly, and I am trying to change the linear.x values from geometry_msgs/msg/Twist command in Python. In Simulink, my subscribed block is also set to the same topic and message, but, the value doesn't change, although Python script is publishing that command.

Any leads would be appreciated.

Thank you.

Hi Usama Faisal,

Based on the description of the issue, i think the issue could be related to middleware. What is the RMW middlware that you are using on ROS2 Foxy on windows ? Can you please share more details about how you installed the Foxy on windows ? Please share the Python script that you are using.

Thanks,
