Inconsistent communication between micro-ROS and ROS2 #1505

Issue template

Steps to reproduce the issue

I have followed this tutorial without using Docker, and using the software versions listed above.

Expected behavior

After uploading the micro-ros-publisher and starting micro-ros-agent from terminal, I expect the following output (copied from tutorial): image

Additionally, ros2 node list and ros2 topic list should show the /micro_ros_arduino_node and /micro_ros_arduino_node_publisher, respectively.

Actual behavior

It seems random how far the output gets:

When the output says participant created, then I can see the node. When it gets to topic created, I cannot see the topic. I have gotten to datawriter created twice, and can see the desired output when I echo the topic.

EDIT: Repeatedly power cycling the teensy while micro_ros_agent is running advances the process. After doing this a few times, I can consistently get to a desired state. It takes about 1 minute for publishing to behave as expected once it begins. Until then, data comes in clumps or is dropped.

Additional information

I have attempted to use Teensyduino 1.58.1 but got this issue and #1378.

Could you detail your build procedure, the build log and the micro-ROS Agent log using the flag -v6?

I'm stuck with the same issue! I upload my code onto ESP32 and then try to run mircoros but it doesn't detect ESP32. It stops at logger setup image I'm using a docker!
