  Actual behavior

  Command times out without returning anything.

The node is showing up as /my_renesas_node and the code is executing fine and getting to the while loop.

When running ros2 node info /my_renesas_node -- I get the following:

The memory configuration file was missing: detail.

I have updated the demo branch with the correct configuration and also upgrade it to Humble. This adds improvements in the parameter server callback, check them out in the micro-ROS app file.

For more details on the parameter server update, you can check this documentation: link. Focus on the micro-ROS Humble section.

@Acuadros95 When running this project now I get: 'RCLC_EXECUTOR_PARAMETER_SERVER_HANDLES' undeclared (first use of this function)

This is odd since the rclc_parameter.h is included and RCLC_EXECUTOR_PARAMETER_SERVER_HANDLES is there.

Any ideas on what the issue might be?

[Acuadros95]

Just tested it locally and it builds, some ideas:

• Check that your micro_ros_renesas2estudio_component submodule is updated to the expected commit (detail).
• Rebuild micro-ROS: Delete the micro_ros_renesas2estudio_component/libmicroros folder and build your project.
• Clean the project and rebuild.
• Make sure that your rclc_parameter.h is equal to this one.

Thanks this worked.

I was working from an older version - sorry for that :)

Hi @Acuadros95

I'm trying to use the UART version of demo 3 now and I'm having a similar issue when compiling I'm getting the following errors at the 'create executor':

RCLC_EXECUTOR_PARAMETER_SERVER_HANDLES' undeclared (first use in this function) & error: passing argument 3 of 'rclc_executor_add_parameter_server' from incompatible pointer type [-Werror=incompatible-pointer-types]

I've pulled the latest foxy files and tried to go through the steps above but still having this issue.

Any ideas?

I've pulled the latest foxy files and tried to go through the steps above but still having this issue.

You should use the commit that is on the repository.

This new paremeter API works targets micro-ROS Humble, but you should not encounter problems communicating with ROS2 foxy.
