Descrição

## Issue template

- Hardware description: ESP32-WROVER-E
- RTOS: ROS2 Humble
- Installation type: micro_ros_setup
- Version or commit hash: Ubuntu 22.04.3 LTS, Arduino 1.8.19
#### Steps to reproduce the issue
# Source the ROS 2 installation
source /opt/ros/$ROS_DISTRO/setup.bash

# Create a workspace and download the micro-ROS tools
mkdir microros_ws
cd microros_ws
git clone -b $ROS_DISTRO https://github.com/micro-ROS/micro_ros_setup.git src/micro_ros_setup

# Update dependencies using rosdep
sudo apt update && rosdep update
rosdep install --from-paths src --ignore-src -y

# Install pip
sudo apt-get install python3-pip

# Build micro-ROS tools and source them
colcon build
source install/local_setup.bash

# Create step
ros2 run micro_ros_setup create_firmware_ws.sh freertos esp32

# Configure step with ping_pong app and serial transport
ros2 run micro_ros_setup configure_firmware.sh ping_pong --transport serial

I followed all these steps no issues till now

# Build step
ros2 run micro_ros_setup build_firmware.sh

when i executed command in between it shows as "colcon build stderr output"
later it will complete the execution without any error 100% build target app.

# Flash step
ros2 run micro_ros_setup flash_firmware.sh

# Download micro-ROS-Agent packages
ros2 run micro_ros_setup create_agent_ws.sh

# Build step
ros2 run micro_ros_setup build_agent.sh

while executing this line it gives

$ ros2 run micro_ros_setup build_agent.sh
source install/local_setup.bash

CMake Warning (dev) at /usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:438 (message):
The package name passed to `find_package_handle_standard_args` (tinyxml2)
does not match the name of the calling package (TinyXML2). This can lead
to problems in calling code that expects `find_package` result variables
(e.g., `_FOUND`) to follow a certain pattern.
Call Stack (most recent call first):

In another terminal if i run
source /opt/ros/$ROS_DISTRO/setup.bash

# Subscribe to micro-ROS ping topic
ros2 topic echo /microROS/ping

ros2 topic echo /microROS/ping
WARNING: topic [/microROS/ping] does not appear to be published yet
Could not determine the type for the passed topic

I have gone through Domail ID and set it to even 0 then also i am getting the same result.
I even refered this and other links regarding the same https://github.com/micro-ROS/micro_ros_arduino/issues/21

This line also gets exicuited correctly code gets uploaded to the board.

#### Expected behavior
You should see the topic messages published by the Ping Pong node every 5 seconds:

user@user:~$ ros2 topic echo /microROS/ping
