I think that the stock Arduino Ethernet Library will not work for ESP32.
I've coded a new one, which can be found here: http://www.fisch.lu/junk/ESP32-Ethernet.zip
I has been written to work with the Olimex ESP32-EVB development board, which uses the LAN8720 chip.
You need to copy the library into the "libraries" folder of your expressif/esp32 installation folder. Do not copy to the regular libraries folder of Arduino!
What Ethernet chip do you use?

Thanks and I am using the LAN8720 chip.
Do you have an example code for arduino.
Nakul93
on 16 Jul 2017
Of course. I integrated some into the package:

I am unable to use EthernetServer function. I have tried including the libraries associated with it from arduino lib but getting errors. Is there any custom function for EthernetServer and EthernetClient.
TIA

I did not implement those. Maybe @me-no-dev knows more about this?
fesch
on 17 Jul 2017
there will be no such thing ;) Ethernet is connected to LwIP so it functions the same as WiFi. You open a client/server and you are good to go. (WiFi Client/Server in this case)

Ok thanks...and one more thing do we have to do those tweaks on LAN8720 board as described here https://sautter.com/blog/ethernet-on-esp32-using-lan8720/

I didn't have to in the library I wrote ...
fesch
on 17 Jul 2017
Its not working ...In the serial monitor it just shows the basic chip info
Nakul93
on 17 Jul 2017
@me-no-dev did you made any tweaks in the connection for the LAN8720 board

@fesch From the examples it seems like the Ethernet library extends the functionality of the base wifi library, would this mean that anything written for wifi would work for ethernet too simply added? If so this is amazing and very much appreciated.
WALLTECH

@WALLTECH That's a good question. I did not try this, but yes, I think that all stuff from within the application layer of wifi may work. In fact, only the underlying network laying is different, but the service calls should be the same.
But I have to admit, that I'm not too deep into all this to really be able to confirm.
fesch
on 26 Jul 2017
@fesch Awesome. To test this, would I attach the hardware, then add from the examples to include ethernet and start it, then try something that's usually wifi and see if it works? Would I need to add Ethernet to a library that uses wifi to use that? I'll test this

No idea ... but I will give it a try tomorrow ... if I find the time to ;)

I yesterday successfully used my Ethernet library with the WiFiClient as well as with PubSubClient in order to connect to an MQTT broker. As said, this worked quite out of the box.
BUT ... using the secured version, thus WiFiClientSecure, on port 8883 did not work and resulted in some nice core panic :(

CPU halted.
I'm soooo stupid!!!
In my example I was calling the connect() method in the asynchronously called WiFiEvent callback, which can't be handled by the WiFiClientSecure. So by leaving the connection code inside the main loop, the use of the secured MQTT version also works!

hey here i am using USR TS232T2 i am trying to connect with my esp32 but i am very confused how to do please help me with the code and connections

uhmm we are not here to help you with that :) we are here to help with bugs with the code. What you show above is serial to ethernet thing... you get UART to Serial adapter, connect the UART side to ESP32, start Serial there and talk to the UART.
Better yet, get an ESP32 board with Ethernet and do not go through this.

please give me examples so that i can understand

@fesch Could you expose the ESP32 - Ethernet library on github so can be added to the platform.io repository and can be easily added to a esp32 project with arduino
Thanks!

Hi fesch,
Can you please give the example code that uses "PubSubClient" that uses this Ethernet library.
I do not how to use this Ethernet library with "PubSubClient".
Thanks & Regards,

Hello guys!
I have a problem with esp-Wroom-32 with ETH_Lan8720 board. I'am using an arduino example code from here :
and i also tryed with your librari Fesch.
https://github.com/fesch/arduino-esp32/tree/master/libraries/Ethernet/examples
I did the wireing like this:
GPIO17 - PHY_POWER : NC - Osc. Enable - 4k7 Pulldown
GPIO22 - EMAC_TXD1 : TX1
GPIO19 - EMAC_TXD0 : TX0
GPIO21 - EMAC_TX_EN : TX_EN
GPIO26 - EMAC_RXD1 : RX1
GPIO25 - EMAC_RXD0 : RX0
GPIO27 - EMAC_RX_DV : CRS
GPIO00 - EMAC_TX_CLK : nINT/REFCLK (50MHz) - 4k7 Pullup
GPIO23 - SMI_MDC : MDC
GPIO18 - SMI_MDIO : MDIO
GND : GND
3V3 : VCC
from the site :
https://sautter.com/blog/ethernet-on-esp32-using-lan8720/
I soldered the NC PIN on the lan8720 board to the enable pin of the oscillator. I added pull down resistor to nc pin and pull up to gpio00.
I get the following errors:
rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee

I dont know what to do , can anyone help me?

@zekageri You are hijacking this issue ticket.
Besides that:
- How long is your wiring? These are 50MHz signals that will most probably not work on breadbords and long cables.
- Did you configure the correct PHY-ID in your software?
- Have you checked the that the 50MHz clock is being turned on?
- Send us a picture of your hardware setup, so we might spot the error.

First of all thank you for the answer. And sorry for hijacking. I dont know where else should i put this issue.
My cables are long A.F and iam using a breadboard.
I think i configure the PHY-ID right. I defined it like this: #define ETH_PHY_ADDR 1 in my sketch.
I checked the clock. Its turned on.
I try to send a picture from it after i shorten the cables
zekageri
on 4 Sep 2018
I shortened the cables. The Serial output still the same. Timed out. I use the pin defines in the sketch and the PHY address define too like this:
define ETH_PHY_ADDR 1
define CONFIG_PHY_LAN8720
define ETH_CLK_MODE ETH_CLOCK_GPIO0_IN
define ETH_POWER_PIN 17
define ETH_TYPE ETH_PHY_LAN8720
define ETH_ADDR 1 // 0
define ETH_MDC_PIN 23
define ETH_MDIO_PIN 18

I have pull up resistors in RXD0 , RXD1 , MDIO , CRS , REFCLK , TX-EN , and a pull down on the NC which is soldered to the enable pin of the oscillator.

There are some other pictures.

Hi Fesch,
Do you happen to have an example code to get the esp32-poe to work with mqtt?
Have managed to run the example https://github.com/OLIMEX/ESP32-POE/tree/master/SOFTWARE/ARDUINO/ESP32_PoE_Ethernet_Arduino
But when trying to add MQTT via PubSubClient to it I fail as I need a reference to WiFi to get in running.
Have also tried with EspMQTTClient library without any luck as it also depend on WiFi.

No, I never tried the PoE as my board has none ... sorry :-/
