I'm using ROS toolbox with matlab 2022a, ros2 foxy and cyclonedds rmw all on ubuntu 20.04.
I created a simple publisher node model within Simulink which publish some message each iteration.
When I generate ros2 node from the Simulink model I set my model's solver type as fix-step with some fixed-time step, which I assume to be the working frequency of the generated ros2 node.
After the node is generated I run it but the publish rate is way faster than I set on the fixed-time step configuration of the model.
Am I missing some settings of the code-generation that controls the working rate of the node?

It seem that this issue will be solved with the new updates of 2022b, especially the loop rate conrtol with ROS2 Time object.
