Hello!
I have a problem when I try to pulish messages in Simulink by using ROS2 Toolbox.
There are no errors in the Diagnostic Viewer and the data are transfrred to the publisher.
But the datas are actually not publushed, if I echo them in the ros2 systems, as it is shown in picture.
Could you help me for this? Thanks!

Hello Xiaochen,
Here are a couple of posts I've made previously to help with diagnosing and fixing communication issues with ROS 2. Please try out the steps outlined in them.
