Running on esp32 but with Ethernet

[alborzs]

I have a setup which works fine on esp32 over Wifi using your library, but the esp32 board that I am using has Ethernet port as well and I would like to use Ethernet instead of Wifi to receive DMX data.

This is the board I am refering to, see below: (but there are other boards as well such as wesp32)

I can not seem to be able to receive any Art-net over Ethernet.

Below is one of your examples just slightly modified:

#define ETH_CLK_MODE ETH_CLOCK_GPIO17_OUT
#define ETH_PHY_POWER 12

#include <Artnet.h>
#include <ETH.h>
#include <SPI.h>

static bool eth_connected = false;
byte ip[] = {192, 168, 0, 90};
byte mac[] = {0x30, 0xAE, 0xA4, 0x9F, 0xF7, 0xA7};
Artnet artnet;

void WiFiEvent(WiFiEvent_t event)
{
    switch (event)
    {
    case SYSTEM_EVENT_ETH_START:
        Serial.println("ETH Started");
        // set eth hostname here
        ETH.setHostname("esp32-ethernet");
        break;
    case SYSTEM_EVENT_ETH_CONNECTED:
        Serial.println("ETH Connected");
        break;
    case SYSTEM_EVENT_ETH_GOT_IP:
        Serial.print("ETH MAC: ");
        Serial.print(ETH.macAddress());
        Serial.print(", IPv4: ");
        Serial.print(ETH.localIP());
        if (ETH.fullDuplex())
        {
            Serial.print(", FULL_DUPLEX");
        }
        Serial.print(", ");
        Serial.print(ETH.linkSpeed());
        Serial.println("Mbps");
        eth_connected = true;
        break;
    case SYSTEM_EVENT_ETH_DISCONNECTED:
        Serial.println("ETH Disconnected");
        eth_connected = false;
        break;
    case SYSTEM_EVENT_ETH_STOP:
        Serial.println("ETH Stopped");
        eth_connected = false;
        break;
    default:
        break;
    }
}

void onDmxFrame(uint16_t universe, uint16_t length, uint8_t sequence, uint8_t* data, IPAddress remoteIP)
{
  // print out our data
  Serial.print("universe number = ");
  Serial.print(universe);
  Serial.print("\tdata length = ");
  Serial.print(length);
  Serial.print("\tsequence n0. = ");
  Serial.println(sequence);
  Serial.print("DMX data: ");
  for (int i = 0 ; i < length ; i++)
  {
    Serial.print(data[i]);
    Serial.print("  ");
  }
  Serial.println();
  Serial.println();
}

void setup()
{
    Serial.begin(115200);
    WiFi.onEvent(WiFiEvent);

    ETH.begin();

    while (!eth_connected)
    {
        delay(10);
    }

    artnet.begin();
    artnet.setArtDmxCallback(onDmxFrame);
}


void loop()
{
    artnet.read();
}

I can see that the boards start up and aqcuires an IP, but nothing else happen.

ETH Started
ETH Connected
ETH MAC: 30:AE:A4:9F:F7:A7, IPv4: 192.168.1.100, FULL_DUPLEX, 100Mbps

Do you have any similar setup that you could test the code using Ethernet?
