Dear,
I want to get the value of an external sensor in real time via ROS2. However, in practice, even when the rate is set to 100 Hz, the values are updated only about once every 3 seconds.
Is this difficult when using custom messages?
I also tried using "Simulink Desktop Real-Time" but it did not make much difference.

I would like to take a look at the Simulink Model settings like Sample Time of the model, QoS Settings of pub/sub blocks. So, please send us the simulink model and custom messages to further debug this issue.
I recommend you to contact us through the MATLAB support for further guidance.

sub(input sensor) settings.
QoS was the same for the others.

@健 Could you explain how you used 'Simulink Deaktop Real-Time' with ROS2?
