Hi Guys,
It seems that i'm too stupid to connect my ESP32-POE to a wired ethernet network. I took the example from the Olimex Githup:
#define ETH_CLK_MODE ETH_CLOCK_GPIO17_OUT
#define ETH_PHY_POWER 12
#include <ETH.h>
static bool eth_connected = false;
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 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()
{
Serial.print("Looping.. ");
Serial.print("IPv4: ");
Serial.println(ETH.localIP());
if (eth_connected) {
testClient("google.com", 80);
}
delay(10000);
}
Power over USB cable, no POE (does also not working with POE and no USB-cable)
Output:
rst:0x1 (POWERON_RESET),boot:0x1b (SPI_FAST_FLASH_BOOT)

Looping.. IPv4: 0.0.0.0
ETH Started
ETH Connected

I see the DHCP request from the ESP32 board on my DCHP server (pfsense firewall), the DCHP server answers with a DCHP-OFFER, so everything should be fine. But nothing happens on the board after the "ETH connected". The Board is not pingable, not local IP nothing.
What do i miss ?
Dev-environment: Arduino 1.8.7 on Win10 with Espressif esp32 1.0.1 installed. Board: OLIMEX ESP32-POE
IP-Switch (100MB) and IP-cables are verified and working with other devices (Labtop).
Any help would be appriciated
Daniel
