Hi everyone,

I am dealing with parameter callback of micro-ROS. My program dont show any issue and I can flash it to my esp32, but I think I cannot get values from the parameter callback. I followed this tutorial: https://github.com/micro-ROS/micro-ROS-demos/blob/galactic/rclc/parameter_server/main.c

Can someone please help me? Thank you in advanced.

Hi @scottitran, Could you please elaborate on your issue?

Fill the repository issue template: link
What is the problem? How are you setting the parameter values?
If you are in galactic, check that FastRTPS is being used as ROS2 middleware: export RMW_IMPLEMENTATION=rmw_fastrtps_cpp

I am going to replicate this, need some details:

Which micro-ROS build system are you using to build and flash? (Including branch)
What are the exact ros2 param set and ros2 param get commands you are using
Whats inside tutorial_interfaces__msg__Num1kb? Did you tests this with a regular std_msgs__msg__Int32?
Whats your ROS2 distro?
