The Simulink block "Get ROS Parameter" slow down ros node

Hi,

using the Simulink block Get Parameter (In the ROS1 toolbox) causes some issues: If I generate a standalone ros node, the generated node runs slower than the same node as a python script. If I remove the Get Parameter block with e.g. a constant block, it works. I use 2020b on a Windows 10 computer and the roscore (meldoic) runs on a remote ubuntu 18.04. I also tried to increase the sampling time to 1,5,20 secs, but it did not help.

Does somebody else have a similar issue?

Thanks

Hi Balint,

It would be good if you can provide some more details to address your issue.

Can you share the model that you are using ?

When you say it runs slower, how slow it is ? How are you measuing frequency ?

Thanks,
