Hi,

I want to use MQTT messages in a real time running Simulink simulation. The MQTT part runs when I run a matlab script in Matlab itself, but I want to integrate it with Simulink.

So my bigger question is: how can I run a MQTT broker in Simulink?

But my more accessible question is: how can I use the workspace in a real time Simulink simulation? Such that I can use the "To Workspace" and "From Workspace" blocks.

Thank you,

Anton

Hi Anton,

Question-1: how can I run a MQTT broker in Simulink?

You can use "MQTT Subscribe" and "MQTT Publish" blocks available in "Simulink Support Package for Raspberry Pi Hardware".

Refer to the following MathWorks documentation to know about:

MQTT Publish - https://www.mathworks.com/help/supportpkg/raspberrypi/ref/mqttpublish.html
MQTT Subscribe - https://www.mathworks.com/help/supportpkg/raspberrypi/ref/mqttsubscribe.html
how to use MQTT blocks - https://www.mathworks.com/help/supportpkg/raspberrypi/ref/publish-and-subscribe-to-messages-using-mqtt-blocks.html

Question-2: how can I use the workspace in a real time Simulink simulation? Such that I can use the "To Workspace" and "From Workspace" blocks.

I found similar question in the community.

Hope this helps!
