Arduino OTA Ethernet (w5500 ethernet )

duong_007 · April 12, 2024, 3:25am

I try to use this library and example code to run on my ESP32 ArduinoOTA/examples/OTEthernet/OTEthernet.ino at master · JAndrassy/ArduinoOTA · GitHub
anyone here have some experience with ESP32 Ethernet OTA

Juraj · April 12, 2024, 5:02am

I have

Hello @duong_007

take a look at this thread.
It handles updating the sketch through EThernet using W5500 and ESP32.

duong_007 · April 12, 2024, 6:15am

It doesn't work on my esp32 do I have to add other library other then ArduinoOTA.h?

duong_007 · April 12, 2024, 6:15am

can u share you code ?

duong_007 · April 12, 2024, 7:56am

I got those error after I remove that class

Deva_Rishi · April 12, 2024, 7:57am

Yeah there was something about modding the Server.h, can't remember the details.
Ah yes.

For fixing ESP32 compile error

To fix ESP32 compile error, just copy the following file into the ESP32 cores/esp32 directory (e.g. ./arduino-1.8.19/hardware/espressif/cores/esp32) to overwrite the old file:

Server.h

@duong_007 "For crying out loud, please use code tags to post code or error messages !

Many thanks to @Juraj & @hamokhalil for responding to this thread.

Deva_Rishi · April 12, 2024, 8:44am

Don't remove the whole 'Server' class, just modify the class to look like this

class Server: public Print
{
public:
    // KH, change to fix compiler error for EthernetWebServer
    // error: cannot declare field 'EthernetWebServer::_server' to be of abstract type 'EthernetServer'
    // virtual void begin(uint16_t port=0) =0;
    //virtual void begin() = 0;
    void begin() {};
};

Juraj · April 12, 2024, 8:49am

sorry for the wrong instruction
in Ethernet.h replace

class EthernetServer : public Server {

with

class EthernetServer : public Print {

Deva_Rishi · April 12, 2024, 9:04am

That does the same thing in the end i suppose since

class Server: public Print

I remove public Server so it become

@Juraj I use it with MQTTs server but since Ethernet_Generic.h doesn't support ESP_SSLClient.h so do you have any solution with this problem ?
