or an example code ?
Thanks for help

@elvis6m I also need your code.

Thom

Thanks @elvis6m for your attention. Here is the siplified code,
//
// Ethernet Settings * i try to use Example "M5Stack/Modules/W5500/Webserver"
// Problem: M5Stack LAN Module works with this settings but only seperate code not together with WiFi at same time,
// _________& OTA was as well not possible
// _________https://m5stack.readthedocs.io/en/master/product-documents/modules/m5stack_lan_module.html
//
// MyProject : connect to home WiFi accesspoint, if done, then Button A pass an UDP message to 2channel LAN relais
//____________connected at the RJ45 M5Stack LAN Module.
// (so fare works only via home wifi accesspint to lan, but not when we connect the crossovercable to M5StackLAN)

@thom said in Lan Module and WiFi:

" char packetBuffer[UDP_TX_PACKET_MAX_SIZE]; //buffer to hold incoming packet,"
this row can be deleted.

@m5-docs
Hello @elvis6m let me ask for an uptate , thank you, best regards Thomas

Thom

Hello There, are the an way to get it solved ? :-/
so far i couldn't find it.

@salty_good Hello, are there any solution meawhile?

Hello Thomas

If I read your code correctly the UDP packets are sent out via WiFi instead of the Ethernet interface. I think you'll need to include Ethernet2 library (from M5 Stack W5500 WebServer example) and then include and declare the following:

#include <Ethernet2.h>
#include <EthernetUdp2.h>

EthernetUDP Udp;

instead of

WiFiUDP Udp, Udp2 ;

The Ethernet interface needs to be initialised as well with something like this (taken from M5Stack W5500 WebServer example):

#define SCK 18
#define MISO 19
#define MOSI 23
#define CS 26

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {
  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED
};
IPAddress ip(192, 168, 1, 177);

  SPI.begin(SCK, MISO, MOSI, -1);
  Ethernet.init(CS);
  // start the Ethernet connection and the server:
  Ethernet.begin(mac, ip);

Note: all of the above is untested and might need some additional fine tuning.

Good luck!

Thanks Felix,
meanwhile i got it work with via ethernet.h , same wway like your post.

But the main skill was and still is unsolved, how get it work with LAN and WIFI together.
OR anway switch within one code between wifi and lan.

so fare i dint found an way to update the sketch .bin via LAN.
Almost all very nice codes working perfekly via WIFI webserver upload .
like :
"HTTPUpload& upload = server.upload();"
or
" t_httpUpdate_return ret = ESPhttpUpdate.update(update_server, 80, update_uri, firmware_version);"

but via ethernet, i am not able to get it wokrk i found nothing so fare :-/

Hello Thomas

glad to hear you've got Ethernet working.

From what I can tell the HTTPUpdate library only supports OTA over WiFi connections. So in order to use Ethernet for OTA I guess you'd need to modify the HTTPUpdate library to use an Ethernet connection instead of WiFi.

Greetings
Felix

Hello again

I think the following library should allow you to switch between WiFi or Ethernet OTA:

https://github.com/espressif/arduino-esp32/tree/master/libraries/Update

Use it with either a WiFiClient or EthernetClient client.
