I cannot see the compiler version here, also this is not the same error as before.

Could you share the build log and explain the procedure you are following?

You can configure the Domain ID in the micro-ROS application: https://github.com/micro-ROS/micro-ROS-demos/blob/70f3cbf27ce12dc9e57e5095b4233553e207d866/rclc/configuration_example/configured_publisher/main.c#L49

Can you show us some tutorials on how to work with this port?

Another think that I'm seeing is that this is not a full micro-ROS port, this is a XRCE-DDS Client port with some hardcoded typesupport of micro-ROS. Won't you be interested...

Hello @Cagdas4, - As far as I understand you have managed to flash your board and run the micro-ROS Client in the MCU. Is that right? - The permissions error...

The serial permission problem shall be solved with one of this options: https://stackoverflow.com/a/27886201

No we don't, the approach shall be to build the agent in the required platform

You need to have the same ROS 2 distro in all parts of your system. Humble and Iron may not be intercompatible.

Is there any Iron node in your ROS 2 dataspace while you are running micro-ROS Humble?
