embeddedRTPS example with NUCLEO-F767ZI

Issue template

• Hardware description: NUCLEO-F767ZIT6
• RTOS: FreeRTOS
• Installation type: STM32CubeIDE, micro_ros_stm32cubemx_utils
• Version or commit hash: galactic

Steps to reproduce the issue

Follow the embeddedRTPS instructions md.

Expected behavior

Visible with either ros2 topic list or Wireshark, or respond to listener on ROS2 side.

Actual behavior

No evidence that it works, but no error on the microcontroller side when monitored with PuTTY.

Additional information

I've double checked that I followed the instructions correctly. The only step I'm unsure about is 5. LwIP -> General Settings -> IP Address Settings (Set here the board address and mask). I used the following settings:

IP: 192.168.001.086
Netmask: 255.255.255.000
Gateway: 192.168.001.001

With ifconfig I see that my own IP and netmask are 192.168.1.84 and 255.255.255.0, respectively for enp3s0. With ip r I see that my gateway is 192.168.1.1. Not sure if I'm supposed to mimic the settings like this.

I made sure to disable WiFi and export FAST-DDS for ros2 topic list and listener. I don't have the board and the computer in an isolated network, but shouldn't I at least be able to see packets from 192.168.1.86 with Wireshark?

ping_test_f7.zip

Start with embeddedrtps.md and the supplied ping_test_f7.zip, then review the NUCLEO-F767ZI, FreeRTOS, STM32CubeIDE, and LwIP settings described in the report. Reproduce the setup and determine whether the board becomes visible through Wireshark or responds to ROS 2 discovery and topic commands; document the cause and a verified working configuration.
