I have two radar sensors, which are two seperate ROS nodes, connected to a machine (NXP BlueBox2) running on Linux with ROS melodic. My PC is connected to that machine via a ssh connection and runs Matlab 2017b as a third ROS node to process radar data in a Matlab script. The radar nodes make us of custom messages.
I now want to export the script using Simulink to create a standalone node. However, I get this 'Error in port widths or dimensions' in the bus selector as shown below. How can I fix this?
The script is going to be implemented using a MATLAB Function later.
