描述
## No Topic Visible if running micro ros agent on Humble, but these are visible if the agent is running on Foxy
- Hardware description: Linux and ESP32
- RTOS: -
- Installation type: micro_ros_setup
- Version or commit hash: Humble
#### Steps to reproduce the issue
I have followed the tutorial from the links below:
https://micro.ros.org/docs/tutorials/core/first_application_linux/
https://micro.ros.org/docs/tutorials/core/teensy_with_arduino/
The issue is, if I run the micro ros agent on ROS Humble (both serial or udp), I don't see any topics and nodes related. But in -v6 I am able to see the data is publishing.

The thing is, I am able to subscribe it through node. But I am not able to see the topic list in the terminal.
I have tried unset ROS_DOMAIN_ID, set the same ROS_DOMAIN_ID, set the same RMW_IMPLEMENTATION, unset the RMW_IMPLEMENTATION. But nothing works.
Then I tried to use foxy to run micro ros agent (using docker ros-foxy), I am able to see the topic list on Humble. And I also able to echo it. as you can see the picture below

#### Expected behavior
I should be able to see the topic list, while the micro ros agent runs in the Humble.
#### Actual behavior
Unable to see the topic list, while the micro ros aget runs in the Humble.
#### Additional information
This is my env, even if I didn't set the same ROS_DOMAIN_ID, and didn't set the RMW_IMPLEMENTATION, if I run the agent on Foxy, it still work and detected on Humble

调研方向
首先,在 ROS 2 Humble 上使用 micro-ROS Agent 重现该问题,并按照描述同时使用 serial 和 UDP,将其 -v6 输出与 Foxy Docker setup 进行比较。检查报告中 ROS_DOMAIN_ID 和 RMW_IMPLEMENTATION 的不同变体。当 agent 在 Humble 上运行时,可以发现 topics 和 nodes 并对其执行 echo,即表示完成。
