ArduinoOTA is failing with W5500 Ethernet module

[Miq1]

### [Updated as I found a local solution worth a feature change]

Hardware:

Board: ESP32 WROOM DevkitC V4
Core Installation version: 1.12.4
IDE name: PlatformIO
Flash Frequency: ?
PSRAM enabled: ?
Upload Speed: n/a
Computer OS: Windows 10

Description:

I am trying to get ArduinoOTA.h working over Ethernet without success. I have a W5500 module connected to the ESP32 and successfully am using that to do several TCP and UDP communication with the ESP.

I finally got there by changing a few lines in ArduinoOTA.h and ArduinoOTA.cpp:

ArduinoOTA.h:4

#include <Ethernet.h>

(instead of #include <WiFi.h>)

ArduinoOTA.h:84

    EthernetUDP _udp_ota;

(instead of WiFiUDP _udp_ota;)

ArduinoOTA.cpp:5
delete #include <WiFiUDP.h>

ArduinoOTA.cpp:119

        // WiFi.macAddress(mac);

(comment out the line - losing the default host name feature!)

ArduinoOTA.cpp:256

    EthernetClient client;

(instead of WiFiClient client;)

I would suggest integrating a similar modification into the core ArduinoOTA to enable Ethernet OTA for everyone needing it.

I am doubting someone is interested at all, but anyway...

There seems to be another issue with ArduinoOTA/W5500. After having run the ESP32 for a day or so, espota.py is unable to trigger an OTA process on the ESP32 anymore. Only a reset of the ESP32 will solve the issue temporarily.
Other TCP and UDP connections are working regardless, so this is confined to the ArduinoOTA communication.

@Miq1 I've just tested your code changes with the Adafruit Ethernet FeatherWing and it works perfectly. It would be nice to have this feature in the official library.

Thanks for the confirmation. For all that it is worth I created a PR for it: #4298

No one is doing anything about this, so I am giving it up. 😠

HI Miq1, I just came across this post, and I am very interested in this solution, to be honest I didn't think ESP32/W5500/OTE was possible, but now i'm going to give it a go, thanks

Hi Bob,

the patch is really simple (as is described in the first post of this issue). You also may look at the commit I made: in my forked repository. But please note that the master repository had quite some commits since. Plus: I left in the mDNS stuff, knowing it will not work via EThernet right away. Using the IP address of your ESP will do.
