Note. - micro-ROS/micro_ros_msgs The ROS 2 Lifecycle has been implemented for micro-ROS as part of the C programming language client library rclc, see rclc_lifecycle for source-code and documentation. 21: Being an extension of the Micro XRCE-DDS Agent, the micro-ROS agent supports being run by the user like this: $ micro-ros-agent --help In addition, the Agent supports running as a service that can be enabled with: $ snap set micro-ros-agent daemon=true If the service is enabled, by default it uses the udp4 transport on port 8888. E : ros2 run micro_ros_agent micro_ros_agent --middleware ced. txt: Setting up micro-ROS Agent. ros2 run micro_ros_setup create_agent_ws. It is important that the Agent is reachable on this step Micro-ROS currently supports three different RTOS, namely NuttX, FreeRTOS, and Zephyr. Multiserial Agent mode is supported on Prosima’s Micro XRCE-DDS level, the micro-ROS middleware implementation. 53 Desired behavior I would like to check This tutorial explains the procedure for creating micro-ROS entities using fully configurable QoS settings. It receives and send micro-ros-agent serial --dev /dev/ttyACM0 baudrate=115200. ros2 run micro_ros_agent micro_ros_agent serial --dev /dev/ttyACM0 --b Hello! I would actually have a second request related to this issue: micro-ros-agent installed from snap release can be launched with command: micro-ros-agent serial --dev /dev/path/to/board So, using launch files, it means that I have to pass this command to the ExecuteProcess function. For this specific example, after publishing 40 messages of the same topic, the application stops working. This sounds like something which should probably be posted on eProsima/Micro-XRCE-DDS-Agent instead of here on ROS Answers or perhaps micro-ROS/micro-ROS-Agent. I am using ROS2 galactic, downloaded the micro-ROS application from source here and the micro-ROS Arduino package from here. The 3pi+ 2040 has a Raspberry Pi 2040 microcontroller.
