4 years ago Each board has the Ethernet interface tested here empirically after manufacturing. So it is likely some sort of software or configuration issue. Try this example:
And follow the instructions here:

The last few times someone encountered similar issue it turned out to be some improper network configuration, unrelated to the the ESP32-POE-ISO. For example here:
TeKiLLa1985
hi i used this code
`#define ETH_CLK_MODE ETH_CLOCK_GPIO17_OUT
define ETH_PHY_POWER 12
include
static bool eth_connected = false;
void WiFiEvent(WiFiEvent_t event) { switch (event) { case SYSTEM_EVENT_ETH_START: delay(1000); Serial.println("ETH Started"); //set eth hostname here ETH.setHostname("esp32-ethernet"); Serial.println("Hostname: esp32-ethernet"); delay(1000); break; case SYSTEM_EVENT_ETH_CONNECTED: delay(1000); 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 testClient(const char * host, uint16_t port) { Serial.print("\nconnecting to "); Serial.println(host);
WiFiClient client; if (!client.connect(host, port)) { Serial.println("connection failed"); return; } client.printf("GET / HTTP/1.1\r\nHost: %s\r\n\r\n", host); while (client.connected() && !client.available()); while (client.available()) { Serial.write(client.read()); }
Serial.println("closing connection\n"); client.stop(); }
void setup() { Serial.begin(115200); WiFi.onEvent(WiFiEvent); ETH.begin(); }
void loop() { if (eth_connected) { testClient("google.com", 80); } delay(10000); }`
and get this output
14:34:58.966 -> e⸮⸮⸮0Q0080⸮X⸮H⸮ETH Started 14:35:00.279 -> Hostname: esp32-ethernet 14:42:36.269 -> ETH Connectedand nothing else happend with a other ESP32-POE-ISO the sketch runs fine i tested it on 2 ESP32-POE-ISO and 3 different networks
I hope some one have a Idea to solve this issue
