Micro-ros something like node get_logger?

edit

I have been checking and publishing to the common logger ROS2 system is just publishing in /rosout [rcl_interfaces/msg/Log]. For sure we can prepare some solution for using this feature in micro-ROS.

Please open the issue and let's talk.

Hello, so it seems there is already a solution by publishing to topic /rosout? Good to know. However I created an issue at micro-ros diagnostic as it seems to me that it fits best here

Meanwhile I tried to publish to rosout topic by myself but I had no luck.

#include <rcl_interfaces/msg/log.h>

rcl_publisher_t publisher_log;
rcl_interfaces__msg__Log msgLog;

// create publisher
RCCHECK(rclc_publisher_init_default(
    &publisher_log,
    &node,
    ROSIDL_GET_MSG_TYPE_SUPPORT(rcl_interfaces, msg, Log),
    "rosout"));


    msgLog.level = rcl_interfaces__msg__Log__INFO;
    msgLog.name.data = (char *)"ESP32 ";
    msgLog.name.size = strlen(msgLog.name.data);
    msgLog.msg.data = (char *)"Hello World";
    msgLog.msg.size = strlen(msgLog.msg.data);
    RCSOFTCHECK(rcl_publish(&publisher_log, &msgLog, NULL));

Everything compiles without any warning and I'm able to flash. During execution, it fails when creating the publisher with this error message

Any ideas of what's going wrong?
