ESP32-PoE Ethernet automatically disconnects & connects again but not reachable

[des]

I programmed the ESP32-PoE board to obtain static IP via Arduino Sketch and to send sensor information to a central point.

The node is powered by PoE and the Ethernet module connects and disconnects on it own. How is that possible?

My Code just collects information from IMU sensor and sends it out via UDP. I tried to ping the node via another machine on the same network but it is not reachabale.

Are you asking why does the Arduino code do that?

If so, this forum may not be the best place to ask as I suspect no-one here wrote the code.

Did you try the Arduino examples that we provide:
