STM32 and ROS 2 Humble connection problem

[omerdurmus61]

I am using the STM32F411 Discovery board and working with STM32CubeIDE. I followed the STM32CubeIDE configuration steps provided in this repository. However, when I run the command ros2 run micro_ros_agent micro_ros_agent serial --dev /dev/ttyUSB0 -v6, the output is as follows

the same as my problem.

Your configuration is sending messages to DDS, check [** <<DDS>> **] logs. How are you checking the reception on the ROS 2 side?
