I do not quite understand how ros2arduino comes here,

The reason I described ros2arduino in the link I mentioned is that I applied ros2arduino with Micro-XRCE-DDS support to the TB3 firmware.
The existing firmware used MicroRTPS, but Micro-XRCE-DDS has not only changed its name, but also many internal codes. Therefore, we developed the ros2arduino library to support this and applied it to the TB3 firmware. So ros2arduino is very closely related to TB3.

Anyway, we modified e-manual because Micro-XRCE-DDS and new firmware were released.

Have you run Micro-XRCE-DDS-Agent properly?
This error occurs because Agent and client cannot communicate and XRCE-DDS entity cannot be created.

Please follow the installation instructions of the e-manual to make sure that your SBC is properly set up.
