Table of Contents

Important Note from v2.3.0

The new EthernetWebServer v2.4.1+ combined with the new Ethernet_Generic v2.7.0+ fixes severe limitation to permit sending much larger data than total than 2/4/8/16K buffer of W5x00 Ethernet.

Important Note from v2.2.2

To be safe for systems using old W5100 shields, the examples are using optional conservative values for SPI clock speed of 14MHz and SPI_MODE0

For SAMD21 M0, such as SAMD Zero, SPI clock speed of 8MHz and SPI_MODE0 are used.

// Default to use W5100. Must change to false for W5500, W5100S, for faster SPI clock
// Must use true for SAMD21, such as Zero, SAMD_FEATHER_M0_EXPRESS, etc.
#define USE_W5100                           true

To use with shields different from W5100, such as W5200, W5500, W5100S, change to

// Default to use W5100. Must change to false for W5500, W5100S, for faster SPI clock
#define USE_W5100                           false

For Arduino SAMD21 Zero, in order to print to Terminal, use SERIAL_PORT_USBVIRTUAL == SerialUSB

// Use this for ARDUINO_SAMD_ZERO, etc. if can't print to terminal with Serial.print
#if defined(SERIAL_PORT_USBVIRTUAL)
  #define Serial          SERIAL_PORT_USBVIRTUAL
  #warning Using SAMD Zero SerialUSB
#endif

Important Breaking Change from v2.0.0

From v2.0.0, breaking changes were made to permit coexistence with ESP32 WebServer and ESP8266 ESP8266WebServer libraries.

The changes will affect only ESP32 and ESP8266 code.

Using ethernetHTTPUpload instead of HTTPUpload

If server using EthernetWebServer, then use ethernetHTTPUpload instead of HTTPUpload. HTTPUpload can be used only with server using WiFi WebServer or ESP8266WebServer

For example, in these examples, server is using EthernetWebServer

just change from

HTTPUpload& upload = server.upload();

to

ethernetHTTPUpload& upload = server.upload();

Please check these new examples to see how to use the new features

  • ~/.arduino15/packages/rp2040/hardware/rp2040/x.yy.zz/platform.txt

With core after v1.5.0, this step is not necessary anymore thanks to the PR Add -DBOARD_NAME="{build.board}" #136.

8.2 To avoid compile error relating to microsecondsToClockCycles

Some libraries, such as Adafruit DHT-sensor-library, require the definition of microsecondsToClockCycles(). To be able to compile and run on RP2040-based boards, you have to copy the files in RP2040 Arduino.h into rp2040 directory (~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0).

Supposing the rp2040 core version is 1.4.0. This file must be copied to replace:

  • ~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0/cores/rp2040/Arduino.h

Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz This file must be copied to replace:

  • ~/.arduino15/packages/rp2040/hardware/rp2040/x.yy.zz/cores/rp2040/Arduino.h

With core after v1.5.0, this step is not necessary anymore thanks to the PR Add defs for compatibility #142.

9. For Portenta_H7 boards using Arduino IDE in Linux

To be able to upload firmware to Portenta_H7 using Arduino IDE in Linux (Ubuntu, etc.), you have to copy the file portenta_post_install.sh into mbed_portenta directory (~/.arduino15/packages/arduino/hardware/mbed_portenta/3.4.1/portenta_post_install.sh).

Then run the following command using sudo

$ cd ~/.arduino15/packages/arduino/hardware/mbed_portenta/3.4.1
$ chmod 755 portenta_post_install.sh
$ sudo ./portenta_post_install.sh

This will create the file /etc/udev/rules.d/49-portenta_h7.rules as follows:

# Portenta H7 bootloader mode UDEV rules

Libraries' Patches

1. For application requiring 2K+ HTML page

If your application requires 2K+ HTML page, the current Ethernet library must be modified if you are using W5200/W5500 Ethernet shields. W5100 is not supported for 2K+ buffer. If you use boards requiring different CS/SS pin for W5x00 Ethernet shield, for example ESP32, ESP8266, nRF52, etc., you also have to modify the following libraries to be able to specify the CS/SS pin correctly.

2. For Ethernet library

To fix Ethernet library, just copy these following files into the Ethernet library directory to overwrite the old files:

You can also use the forked and modified library at Patched Ethernet

3. For EthernetLarge library

To fix EthernetLarge library, just copy these following files into the EthernetLarge library directory to overwrite the old files:

You can also use the forked and modified library at Patched EthernetLarge

4. For Ethernet2 library

To fix Ethernet2 library, just copy these following files into the Ethernet2 library directory to overwrite the old files:

To add UDP Multicast support, necessary for the UPnP_Generic library:

You can also use the forked and modified library at Patched Ethernet2

5. For Ethernet3 library

  1. To fix Ethernet3 library, just copy these following files into the Ethernet3 library directory to overwrite the old files:

You can also use the forked and modified library at Patched Ethernet3

6. For UIPEthernet library

To be able to compile and run on nRF52 boards with ENC28J60 using UIPEthernet library, you have to copy these following files into the UIPEthernet utility directory to overwrite the old files:

7. 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:

8. For fixing ESP8266 compile error

To fix ESP8266 compile error such as

error: 'class EthernetClass' has no member named 'init'
Ethernet.init (USE_THIS_SS_PIN);

just rename the following file in ./arduino-1.8.19/hardware/esp8266com/esp8266/libraries/Ethernet directory

  • From Ethernet.h to Ethernet_ESP8266.h

HOWTO Use analogRead() with ESP32 running WiFi and/or BlueTooth (BT/BLE)

Please have a look at ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to have more detailed description and solution of the issue.

1. ESP32 has 2 ADCs, named ADC1 and ADC2

2. ESP32 ADCs functions

  • ADC1 controls ADC function for pins GPIO32-GPIO39
  • ADC2 controls ADC function for pins GPIO0, 2, 4, 12-15, 25-27

3.. ESP32 WiFi uses ADC2 for WiFi functions

Look in file adc_common.c

In ADC2, there're two locks used for different cases:

  1. lock shared with app and Wi-Fi: ESP32: When Wi-Fi using the ADC2, we assume it will never stop, so app checks the lock and returns immediately if failed. ESP32S2: The controller's control over the ADC is determined by the arbiter. There is no need to control by lock.

  2. lock shared between tasks: when several tasks sharing the ADC2, we want to guarantee all the requests will be handled. Since conversions are short (about 31us), app returns the lock very soon, we use a spinlock to stand there waiting to do conversions one by one.

adc2_spinlock should be acquired first, then adc2_wifi_lock or rtc_spinlock.

  • In order to use ADC2 for other functions, we have to acquire complicated firmware locks and very difficult to do
  • So, it's not advisable to use ADC2 with WiFi/BlueTooth (BT/BLE).
  • Use ADC1, and pins GPIO32-GPIO39
  • If somehow it's a must to use those pins serviced by ADC2 (GPIO0, 2, 4, 12, 13, 14, 15, 25, 26 and 27), use the fix mentioned at the end of ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to work with ESP32 WiFi/BlueTooth (BT/BLE).

Important:

  • The Ethernet_Shield_W5200, EtherCard, EtherSia libraries are not supported. Don't use unless you know how to modify those libraries.
  • Requests to support for any future custom Ethernet library will be ignored. Use at your own risk.

2. How to select another CS/SS pin to use

The default CS/SS pin is GPIO4(D2) for ESP8266, GPIO22 for ESP32, 10 for all other boards.

If the default pin is not correct, the easiest way is to select the CS/SS pin (e.g. 22) to use as follows:

// To override the default CS/SS pin. Don't use unless you know exactly which pin to use
#define USE_THIS_SS_PIN   22

3. How to use W5x00 with ESP8266

To avoid using the default but not-working Ethernet library of ESP8266, rename the Ethernet.h/cpp to Ethernet_ESP8266.h/cpp to avoid library conflict if you're using the Arduino Ethernet library. The Ethernet_Generic, Ethernet2, Ethernet3, EthernetLarge library can be used without conflict.

These pins are tested OK with ESP8266 and W5x00/W5100S/W6100

// For ESP8266
// Pin                D0(GPIO16)    D1(GPIO5)    D2(GPIO4)    D3(GPIO0)    D4(GPIO2)    D8
// Ethernet           0                 X            X            X            X        0
// Ethernet2          X                 X            X            X            X        0
// Ethernet3          X                 X            X            X            X        0
// EthernetLarge      X                 X            X            X            X        0
// Ethernet_ESP8266   0                 0            0            0            0        0
// D2 is safe to used for Ethernet, Ethernet2, Ethernet3, EthernetLarge libs
// Must use library patch for Ethernet, EthernetLarge libraries
//Ethernet.setCsPin (USE_THIS_SS_PIN);
Ethernet.init (USE_THIS_SS_PIN);

4. How to increase W5x00 TX/RX buffer

  • For Ethernet_Generic library only, simply use as follows to have large buffer similar to EthernetLarge library
#define ETHERNET_LARGE_BUFFERS
  • For Ethernet3 library only, use as follows
// Use  MAX_SOCK_NUM = 4 for 4K, 2 for 8K, 1 for 16K RX/TX buffer
#ifndef ETHERNET3_MAX_SOCK_NUM
  #define ETHERNET3_MAX_SOCK_NUM      4
#endif

Ethernet.setCsPin (USE_THIS_SS_PIN);
Ethernet.init (ETHERNET3_MAX_SOCK_NUM);

5. How to adjust sendContent_P() and send_P() buffer size

sendContent_P() and send_P() buffer size is set default at 4 Kbytes, and minimum is 256 bytes. If you need to change, just add a definition, e.g.:

#define SENDCONTENT_P_BUFFER_SZ     2048

Note that the buffer size must be larger than 256 bytes. See Sending GZIP HTML ~ 120kb+ (suggested enhancement).

We can use drag-and-drop method to drag-and-drop the compiled hex file to CURIOSITY virtual drive.

If success, The LED blinks slowly for 2 sec. The LED will blinks rapidly for 2 sec if failure

For example, to run Change_Interval example, use Arduino IDE to compile, and get the Change_Interval.ino.hex file. For Ubuntu Linux, the file is stored in directory /tmp/arduino_build_xxxxxx

After drag-and-drop the Change_Interval.ino.hex into CURIOSITY virtual drive, the code will run immediately if successfully loaded (LED blinks slowly)

ethernetwebserver's Issues

ESP32 keeps rebooting when trying to use pointers.

Hello,

It's possible to use pointers when creating the EthernetWebServer class object, to change port number on setup?

I can compile the code using sometihng like this...

EthernetWebServer *server

void setup() {
  server = new EthernetWebServer(desiredPortNumber);
  server->begin();

But when I turn on the board, it keeps rebooting non stop.

Rebooting...

That's what happens when I turn on the board...

Can you give me some advice about what to do to solve this, or, any other way to change port number on another part of the code?

Hi,
Does this library support MDNS for esp32?
Arduino for esp32 has ESPmDNS library but I cant find any example here...

Compile Error on Teensy 4.1

Thank you for your efforts. I was very happy to find a library that works on Teensy 4.1 however I am unable to compile the WebServer example.

Arduino Mega not work pin SS

Good day,

if I use Arduino Mega output number 53 for SS pin, wiznet 5500 is not functional. If I use pin 10 Arduino, everything works.

Used standard ethernet library in version 2.0.0.

server.authenticate problem

If I use newest ver. 1.8.1 (when I use 1.7.0 work correct)

  • I get problem with server.authenticate
  • server.on(F("/"), {
    if (!server.authenticate(www_username, www_password))
    {
    return server.requestAuthentication();
    }
    server.send(200, F("text/plain"), F("Login OK"));
    });

If you call above you don't get LOGIN windows, but clear window and callin finis with :
return server.requestAuthentication();

  • I testing on ESP32-S2 + W5500 + Ehtrenet3 lib (this lib I patchet library)

Unable to Compile Any EthernetWebServer Examples on ESP32-Wrover-E

I have tried multiple items at this point, to include reinstalls and different machines on Windows 10. I have verified the prereqs per the instructions here--I was working offline, so I also checked on an online machine with the latest direct downloads for dependencies etc. I should note that I used the following ESP32 ethernet example and verified that my W5500 board and my ESP32 Devkitc_v4 board with wrover-E chip are functional and connecting properly otherwise--https://github.com/PuceBaboon/ESP32_W5500_NTP_CLIENT.

Finally, I tried variations of the fix for the Server.h file and made sure that the ethernet.h, ethernet.cpp, and ethernetserver.cpp are the correct fixes per recommendations.

I get the below-pasted set of errors when I try to compile, and it is the same in all variations on both machines and in different versions. It seems to be a type mismatch or something. I have the board manager set at 115200 baud speed, correct port, ESP32 Wrover Module board selected, and default 4MB partition scheme with SPIFFS.

I am just beginning to approach code professionally, so assistance on this for a poor former Controls Engineer would be greatly appreciated. I really need this to work. I am trying to flesh out an ethernet connection that can connect to a basic HTML/HTTP website for external control, (no PoE won't work here, and no Wi-Fi is not an option), so I'd take recommendations as well for alternate paths to make something exactly like this work but for ethernet https://randomnerdtutorials.com/esp32-access-point-ap-web-server/.

ADAFRUIT METRO M4 EXPRESS AIRLIFT (WIFI) - LITE problems

Feature Request: Add a RequestHandler subclass which passes the server to the function

Hello,

I am currently examining the feasibility of switching from our current custom (but extremely fast) Arduino web server code.
In doing so, I noticed that the default on methods, and FunctionRequestHandler only call functions which have no arguments.

That is a serious issue, since it means the server code must be a global, and breaks all sorts of best practices.

My cheap and dirty work around is something like this, but due to the next bug, I can't even test it with our current code base.

typedef vl::Func<void(EthernetWebServer&)> THandlerFunctionWithServer;
class FunctionRequestHandlerWithServer: public FunctionRequestHandler {
public:
    FunctionRequestHandlerWithServer(THandlerFunctionWithServer fn,
                                     THandlerFunctionWithServer ufn, const String &uri, HTTPMethod method)
    : FunctionRequestHandler([](){}, [](){}, uri, method), _fns(fn), _ufns(ufn)
    {
    }

    bool handle(EthernetWebServer& server, HTTPMethod requestMethod, String requestUri) override
    {
        ETW_UNUSED(server);

        if (!canHandle(requestMethod, requestUri))
            return false;

        _fns(server);
        return true;
    }

    void upload(EthernetWebServer& server, String requestUri, HTTPUpload& upload) override
    {
        ETW_UNUSED(server);
        ETW_UNUSED(upload);

        if (canUpload(requestUri))
            _ufns(server);
    }

protected:
    THandlerFunctionWithServer _fns;
    THandlerFunctionWithServer _ufns;
};

void handlerFunction(EthernetWebServer& server) {
    server.send(404, "application/json", "Something";
}

Edit:
With something like this, the EthernetServer().on(...) functions can be overloaded to support both versions.

NTP Server not working on teensy 4.1

Thank you for your efforts in continuing to update the library.

I tried the NTP example. The Teensy 4.1 gets an IP address but does not receive a response from the NTP server.

I tried changing the timeserver address to "129.6.15.28", but still no response.

I have set up a simple sketch that serves a html on /login. Here is the code

byte mac[] = {0xAA, 0xAA, 0xAA, 0xAA, 0xAA, 0xAA };
void setup()
{
  Ethernet.init(5);
  SerialUSB.begin(9600);

  Ethernet.begin(mac, IPAddress(192, 168, 1, 177), IPAddress(192, 168, 1, 1), IPAddress(192, 168, 1, 1), IPAddress(255, 255, 255, 0)); // 'settings' is a struct declared elsewhere.
  webServer = EthernetWebServer(80);

  webServer.on("/login", [](){ // /login handler
    webServer.send(200, "text/html", webpage);
  });
}

void loop()
{
  webServer.handleClient();
}

Everything works fine and the load time is not too slow. The problem is that when I load the page multiple times (aka. Send multiple GET requests with my browser), after the sixth time I refresh, the Arduino hangs. Everything gets blocked, I've checked the loop() with some SerialUSB.println(), and indeed it is frozen. This is probably the Arduino running out of SRAM causing the problem.
The device itself is an Arduino Zero compatible board with a ARM Cortex M0+ processor, so 256kB of Flash and 32kB of SRAM and the ethernet hardware is a W5500.

EthernetWebServer does not read and send html.h file to web browser

Hello Khoih,

I am trying to read a file test.h containing html code to send it to the web browser but shows a blank page. I am using Arduino Mega and Ethernet shield W5100 Wiznet.

#include test.h

void handleRootl()
{
String root_code = html_page;
server.send(200,"text/html",root_code);
}

test.h file contains:

const char html_page[] PROGMEM = R"=====(
<!DOCTYPE HTML>

<html> ........ </html>
)=====";

The sketch works fine with ESP8266WebServer. Please let me know how to solve it.

Wemos D1 mini and W5500 not work in standard SS/CS pin

  • Ethernet (arduino v.2.0.0) - not work, + unexpected system restarts

  • Ethernet3 (v.1.5) - not work default cs/ss pin , after changing the pin to GPIO5 (wemos D1) it works fully (another suitable pin can be used). It is even possible to use the default pin, but it must be declared Ethernet.setCsPin (15);

  • Ethernet2 (v.1.0.4) - not work, (works but need to add code Ethernet.init(15)), as the previous case

Udp Multicast

I am trying to make the UdpSendReceive example work in Multicast mode, it receive all the packets I send, but it never sends the reply message.

The unicast mode works as it should.

I just changed the line Udp.begin(localPort); to Udp.beginMulticast(IPAddress(23,255,255,250),1900);

#include "defines.h"

unsigned int localPort = 1900;    //10002;  // local port to listen on

char packetBuffer[255];          // buffer to hold incoming packet
char ReplyBuffer[] = "ACK";      // a string to send back

// A UDP instance to let us send and receive packets over UDP
EthernetUDP Udp;

Is there something missing in the code to make the multicast works ?

ESP32 heap corrupting after update to 1.4.0 or 1.5.0

Hi,
I have finished ESP32 project with your great library, which periodically send json file as response to AJAX request.
Wifi and BT are off. Everything works fine, but after update my version 1.3.1 to 1.4.0 or 1.5.0 after each response is free heap memory decreased by 56 bytes until system crash.
All is fine with version 1.3.1.

Break of min and max functions on Arduino Sam Due

Hi, I'm trying to use you library but after adding it to my project I get an error on min and max functions that was previous inside my code.
Before adding your library everything works well.
I've patched platform.txt for SAM Due, as you said. I'm using also EthernetENC.
Is It my fault? I forgot to patch something?
To make my code working again I've to put this definitions after including your library:

#ifndef max
#define max(a,b) (((a) > (b)) ? (a) : (b))
#endif

#ifndef min
#define min(a,b) (((a) < (b)) ? (a) : (b))
#endif

Thanks,
Paolo

AdvancedWebServer example give me wrong ip HTTP EthernetWebServer is @ IP : 1.0.1.0

i download and try to use a lib from you and simple example with RPI2040 PICO evb board with w5100S.

the chip in RPI2040 PICO LAN WIZ NET BOARD IS W5100S, S-letter after w5100. if this is important for your software i think need to rework a little.

i read the code that you write for spi pins for this evb board. serial monitor say that is connected but ip is not of dhcp or static that i try to give to make web server active in my network
here is some info from serial monitor :

Something wrong in http response header

Hi
I'm using this library for my ESP32 and w5100 ethernet board.
Recently I found that there's unexpected chars (0x20, 0x91) in http reponse after "HTTP/1.1" and no http status code which causes http basic auth fail and something strange .
Is there anything I can do or maybe to get an update?
Thanks for help.

@v1.81 + Arduino 1.8.16 + Ethernet.h

WiFi and Ethernet Bridge?

Perhaps I'm missing this ability as an inherent part of the base libraries, but I cannot seem to get Wi-Fi and Ethernet servers to operate in one program. The intent is to connect one or the other based on if Ethernet is physically connected, or default to Wi-Fi if Ethernet isn't connected at startup. Removing Ethernet would start the Wi-Fi AP and server. Both listen for clients after switching.

I have not been able to successfully split the startup functions and declarations based on input feedback. I can compile a logic tree that starts one or the other, but there seems to be a problem with the class when trying to connect. It appears to me that the items to consider are as follows:

EthernetServer server( );
Ethernet.begin( );
EthernetClient client = server.available( );

WiFiServer server( );
WiFi.softAP( );
server.begin ( );
WiFiClient = server.available( );

Is it possible to merge these two functionally without major changes?

Consecutive page refreshes finally leads to data corruption and Connection Refused

Dear all, first of all i need to congratulate you on this wonderful library. I dont want to waste anyones time but I am desperate to find a solution. I can see that this topic is somehow similar to a previous one but I am confident that it is a valid case to be examined.

I am using an arduino Mega with an ethernet shield 2. The device is powered from USB cable directly connected to laptop. I have developed my own program and came across some issues that I couldnt explain. Finally i went back to the drawing board and conducted my tests with the Simple Authentication example as provided. I could replicate the issues with this example so it makes me think there is a bug somewhere in the library.

The bug is as follows: after consecutive refreshes the arduino starts sending less and less data and finally i get the message connection refused on the browser. The arduino seems to be stuck as it produces nothing. However it responds to pings Ok.

Here is some info on how to replicate the bug:

Arduino 1.8.13
Arduino Mega plus Ethernet Shield 2 featuring a W5500.
Example: Simple Authentication
Page to refresh: $IP ADDRESS$/login
Browser: Chrome and Firefox
Configuration settings: using either Ethernet or Ethernet2 library

Load the page and do about 200 refreshes. Refreshes should be done once the page is loaded. On every refresh the arduino should send 350 characters with the content

<html><body><form action='/login' method='POST'>To log in, please use : admin/password<br>User:<input type='text' name='USERNAME' placeholder='user name'><br>Password:<input type='password' name='PASSWORD' placeholder='password'><br><input type='submit' name='SUBMIT' value='Submit'></form><br>You also can go <a href='/inline'>here</a></body></html>

After 150-200 refreshes the arduino starts sending less and less characters. Please see provided log further down.

Also, if the refreshes are faster the arduino will also report corrupted data on its parsed received headers. Please see provided log further down.

Here is a perfect page refresh log that sends the full 350 character long web page:

And eventually you get the ERR_CONNECTION_REFUSED from the browser. The arduino at this point seems to be stuck as it does not produce and logs but weirdly it responds to pings Ok.

Finally, when someone goes crazy with the page refresh and keeps refreshing very fast, i can see corrupted data on the headers too...See below (please note how the ip address is not correctly filled in):

Help with the ESP32

Hi there,
I have to admit that in using this library I am completely lost.

I have a m5STack with an ethernet unit (ESP32 & W5500) and cannot compile any of the demos.
Because I don't know how and where to define my hardware.

If there is a ready-made demo code for ESP32 and W5500 Ethernet Shield, I will be very happy.

Thanks,
Armin

ESP32 with ENC28j60 slow simple HTTP post request

Slow HTTP POST request on ENC28j60 with ESP32

ESP32 as web client using enc28j60 to post request on local server working very slow around >2200ms.
same request from POSTMAN application takes only 100ms.

Steps to Reproduce

Using generic simple http post example.

Expected behavior

Post request supposed to be completed within <200 ms.

Actual behavior

>2200 ms is consumed by httpclient post request.

Teensy 4.1 : Equivalent for "server.on"

A very nice and complete webserver example has been posted by David Bird at:

https://github.com/G6EJD/ESP-SMART-Thermostat

I am trying to convert that example to use your library with a Teensy 4.1 but getting a compile error for

server.on("/", HTTP_GET, [](AsyncWebServerRequest * request) {

Is there an equivalent to that statement?

Thank you.

Problem with page larger than 2k.

Hello, I don't know exactly where the problem is, but if I try to create an html page larger than 2k, a part of the page will load in the browser (corresponds to a size of about 2k) and then restart for an internal error. I use W5500 (ethernet3), esp8266 (sdk 2.7.1), ethernetwebserver (v 1.0.7).

`void handleRoot()
{
char temp[3000];
uptime::calculateUptime();
float x1 = newVoltageSend;
int x2 = uptime::getDays();
int x3 = uptime::getHours();
int x4 = uptime::getMinutes();
int x5 = uptime::getSeconds();

snprintf(temp, 3000,
"\

Resend\ Reboot\ Upgrade\\ ", x1, x2, x3, x4, x5); server.send(200, "text/html", temp); }`

.

I initialize ethernet according to the procedure from the example to the size 4k, I also tried a bigger one.
// Use MAX_SOCK_NUM = 4 for 4K, 2 for 8K, 1 for 16K RX/TX buffer
#define ETHERNET3_MAX_SOCK_NUM 4
Ethernet.init (ETHERNET3_MAX_SOCK_NUM);
Ethernet.begin(eeprom_config.mac, ip, subnet, gateway, dns_server);

I don't know where I can make a mistake, can you help me how to send a larger page as 2k.
Thank you

PS: unfortunately the html code does not display correctly here, but it is valid.

Server never returns after "Submit"

The attached code was working fine but is not working on the Teensy 4.1

It is a simple webserver which responds with a Table and a Submit button.

When the website is accessed, everything looks good. However, when I press the submit button, I noticed that the request never finishes on the Teensy side (suddenly stops) and the micro just hangs.

That same code worked before fine ...

Too big for UNO R3?

Just to confirm: UNO R3 is not supported, right? I have the Ethernet shield but I get this:

Sketch uses 35252 bytes (109%) of program storage space. Maximum is 32256 bytes.
Global variables use 2658 bytes (129%) of dynamic memory, leaving -610 bytes for local variables. Maximum is 2048 bytes.
Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.

Ethernet_Large + Lib Patches give always IP:255.255.255.255 || can not server.streamFile () from SPIFFS

Hello,
I'm trying to set up a web server with a W5500 Shield (and a m5Stack).
Since I use Bootstrap and the files are> 40 kB (up to 200 kB) I used the Ethernet_Large Library.
Without your lib patches, the html part loads, but the ESP crashes with the large css + js files.
When I import your lib patches, I only get IP: 255.255.255.255 addresses, regardless of whether I choose static or dynamic. (If I use the original Ethernet_large sources again, I get the correct IP address)

Unfortunately loading SPIFFS doesn't work with your library:

  File file = SPIFFS.open ("/bootstrap.min.css.gz", "r");
  size_t sent = server.streamFile (file, "text/css");

so I added another library:
Effortless_SPIFFS.h https://github.com/thebigpotatoe/Effortless-SPIFFS
This loads the files stored in SPIFFS into a string at lightning speed, which I then transfer to your lib:
Unfortunately the Effortless_SPIFFS doesn't load and extract .gz files (which will server.streamFile() do and server.send() not, I presume ), so I have to use the uncompressed ones ...

bool handleFileRead (String path) {
  String sHTML;
  char cPath [20];
  if (path.endsWith ("/")) path + = "index.html";
  if (SPIFFS.exists (path)) {
    path.toCharArray (cPath, 20);
    String contentType = getContentType (path);
    fileSystem.openFromFile (cPath, sHTML); // <- Effortless_SPIFFS.h
    server.send(200, contentType, sHTML);
    return true;
  }
  return false;
}

Is it possible, to load Files large than >40 kb from SPIFFS and send it to server() - directly with Ethernet_Large, and server.streamFile() or with server.send() ?

Thank you verry much,,
Armin

Upload speed it's slow

Hi,
I'm very happy with your library, so far; just one issue: uploadinglarge files it's very slow.
For example a 170KB file it's taking around 30 seconds to upload it.
I'm using ESP32 + WIZ5500 shield on a SPI bus.
I've changed the HTTP_UPLOAD_BUFLEN to 4K and 16K, no visible change on upload speed.
Downloading the file, it's way more faster (around 1 second).
Thank you,
Alex

Error on PlatformIO "multiple definition of `EthernetWebServer::.."

Hello,

Due to the way the code is written, #include <EthernetWebServer.h> can never be used in a header file.

It always results in a multiple definition error.

I believe the problem can be traced to these two lines in "EthernetWebServer.h"

#include "EthernetWebServer-impl.h"
#include "Parsing-impl.h"

It may be better to convert the "*-impl.h" files to instead be ".cpp" files, which are linked at compile time.

Support for STM32F Series

Hi,

Your README says that From v1.0.2+, the library supports ... STM32F series .... But when I attempt to compile the PostServer example for an STM32F103, I get

WARNING: library functional-vlpp claims to run on avr architecture(s) and may be incompatible with your current board which runs on STM32F1 architecture(s).

and subsequent complaints that PGM_VOID_P and memccpy_P aren't defined

Can you please confirm what STM32F boards are supported and/or if there are any simple defines I need to change to use the STM32F103

Cheers

Andy

Arduino IDE version: 1.8.12

Not Working With Default ETH Library

I am trying to use this webserver with the default ETH library for ethernet. The board is the OMILEX ESP32-GATEWAY, which works with the ETH library by default. Currently the Ethernet initializes and works (it is able to receive pings from other devices), but it does not receive web requests (connection refused).

Is there something with the pin mapping that needs to be done to make this work?

#include <ETH.h>
#include <EthernetWebServer.h>
EthernetWebServer ethernetServer(80);

void handleEthernetRoot(){
    ethernetServer.send(200, "text/plain", "Hello from ESP32 Ethernet!");
}

void setup()
{
  Serial.begin(115200);
  ETH.begin();
  ethernetServer.on("/", handleEthernetRoot);
  ethernetServer.begin();
}

void loop()
{
      ethernetServer.handleClient();
}

fatal error: functional-vlpp.h: No such file or directory

In Arduino IDE 1.8.19
with E. Philhower RP2040 core (what woorks in other cases very well)
I tried to use your example

AdvancedWebServer_RP2040_SPI1.ino

with a "WIZnet 5100S-EVB-Pico" board, that woorks fine with the lib "https://github.com/WIZnet-ArduinoEthernet/Ethernet"
I replaced this lib with your lib.

in your original Exaple AdvancedWebServer_RP2040_SPI1,
I made the following mutations
in the defines.h :

#define USING_SPI2 false // true //muths
IPAddress ip(192, 168, 1, 179); //muths

At the Verify process the have this error msg:

I am using ESP-12E with ENC28J60 Ethernet module and Arduino IDE version 1.8.16 with ESP8266 core 3.0.2

Use the EthernetWebserver and ESP8266Webserver simultaneously

I want to use wifi capability of the esp8266 and connect a Ethernet module(W5500) to have LAN.

I want to connect to different network but serve the same webserver.

So that when I access the ethernet IP and Wifi IP it will show the same webserver.

Dependencies in library.json

Why is the functional library not listed in library.json under dependencies so that PlatformIO can install it automatically?

ESP32 and W5100 help

Hi,

I recently came across your library and was breaking my head to try and integrate a w5100 ethernet shield and ESP32. I have a project where i need to use ethernet when the setting is enabled via an app. I wanted to integrate the ethernet shield ( Which works with my Arduino Mega).

I am unable to go past the Ethernet.Begin(). The Example I'm using is WebClientRepeating.ino .
I am working on PlatformIO core 5.1.1.

I replaced my platformio.ini file with the one provided.

The following changes were made:

    default_envs = esp32
    framework = arduino
    lib_deps= 
            khoih-prog/EthernetWebServer@^1.3.1   
            khoih-prog/Functional-Vlpp@~1.0.2
            PaulStoffregen/Ethernet@~2.0.0
            PaulStoffregen/EthernetLarge@~2.0.0
            adafruit/Ethernet2@~1.0.4
            sstaub/Ethernet3@~1.5.3
            jandrassy/EthernetENC@~2.0.1
           UIPEthernet/UIPEthernet@~2.0.9

PS: PlatformIO couldnt download the following
Library Manager: Installing PaulStoffregen/EthernetLarge @ ~2.0.0
Warning! Could not find the package with 'PaulStoffregen/EthernetLarge @ ~2.0.0' requirements for your system 'windows_amd64'
Library Manager: Installing UIPEthernet/UIPEthernet @ ~2.0.9
Warning! Could not find the package with 'UIPEthernet/UIPEthernet @ ~2.0.9' requirements for your system 'windows_amd64'

Next I went about replacing the files from the LibraryPatches folder. I replaced Ethernet,Ethernet2&3 and EthernetLarge.

Next I opened Server.h and replaced the contents of Server.h with the included Server.h file inside LibraryPatches/esp32/Server.h

Next I copied the code from the Example: WebClientRepeating.ino to my Main.cpp and copied the defines.h inside my src folder. My folder structure is as follows:

Src/
main.cpp
defines.h

The code gets compiled and uploads successfully.

Where I open my Serial Monitor:

clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00

Starting WebClientRepeating on ESP32 with W5x00 using Ethernet Library
EthernetWebServer v1.3.1
[EWS] =========== USE_ETHERNET ===========
[EWS] Default SPI pinout:
[EWS] MOSI: 23
[EWS] MISO: 19
[EWS] SCK: 18
[EWS] SS: 5
[EWS] =========================
[EWS] ESP32 setCsPin: 22

after this Nothing happens. Ive tried changing it to pin 5 and still no change. The TX LED on my Ethernet Shield blinks quite frequently.

The Connection between ESP32 and W5100 is as follows:

ESP32 | W5100
23 MOSI 11
22 CS 10
19 MISO 12
18 SCK 13

I tried Interchanging MOSI and MISO ie: 23 to 12 and 19 to 11. That also made no difference.
I tried using the ICSP pins, even that made no difference.

Ive tested the Ethernet Shield with my arduino mega, and the board works fine. So i know the board works.Cannot understand why ESP32 wouldnt work.

AdvancedWebServer example give me wrong ip HTTP EthernetWebServer is @ IP : 0.0.0.0

Describe the bug

I have a new board SAMD21 M0 size as Arduino UNO, compatible with Arduino M0, native port, with ethernet shield Wiznet W5100.
I tried example code Hello World, edit all serial.print to serialUSB.print and load to cpu over Native USB port, I have selected Arduino M0 board in Arduino IDE. Then, I get this from serial monitor:

I have a company network on 192.168.0.x with DHCP. Before, this shield I used with MEGA and webduino, working.
Thank you.

Needing help !

I know that it is not an issue related, but I am geting mad trying to use the EthernetWebServer
library together with the https://github.com/Aircoookie/Espalexa.

I did some small changes in the Espalexa library and now it compiles wihthout any error, the espalexa server works, but the alexa never discovers the devices.

I am using the W5500, the TCP server and the webserver work very well and fast, but to finish my project I need that the Espalexa library works with this one.

I know that it is compatible with the LAN8720 module, but I can't see why it is not working with the W5500. I don't know the differences between them, as I am not espacialist. I wish I were !

So, if you could help me to find out what I have to change in the Espalexa for it work I will be vary gratefull.

I can pay for your time if you julge necessary.

Sorry If I annoyed you with my problem, it was not my intent.

  • PlatformIO Core [5.2.5] · Home [3.4.1]
    • Platform: Teensy 4.15.0
  • Builder: Windows 10 21H1
  • EWS 2.1.2

Describe the bug

I try to send a html (actually a whole SPA) from an SD card over ethernet. But streaming files is not working.

Steps to Reproduce

  • Get any SD card.
  • Put a file on it
  • Get your teensy 4.1 PlatformIO and install EthernetWebServer.
  • Apply patches, insert SD Card
  • Init the built-in SD card library SD.begin(BUILTIN_SDCARD); in setup()
  • At any point in request handler function insert:
if (SD.exists(path_to_file.c_str()))
{
    File myFile = SD.open(path_to_file.c_str());
    uint32_t myFileSize = myFile .size();
    Serial.println("SIZE to send: " + String(myFileSize)); // Debug check size
   
    server.streamFile(myFile , getContentType(path_to_file));
    myFile.close();
    return;
 }

Expected behavior

The myFile is send to the client

Actual behavior

The debug check files size output shows correct size of file to send.
The browser fails with net::ERR_CONTENT_LENGTH_MISMATCH 200 (OK)
Reported: File is incomplete (Actually no file is written. I doubt that bytes are sent at all)

Debug and AT-command log (if applicable)

Problem with your custom ethernet library (W5500-Teensy 4.0)

Hi! I'm working with your library with a teensy 4.0 and Ethernet Chip W5500. With default Ethernet library, I can't send messages longer than 2K. When I paste your custom files of that library I can't send any messages. "HTTP_MAX_CLOSE_WAIT" Timeout.
Do you have any suggestion of what may be my problem?

WebServer not functioning on Teensy 4.1

Describe the bug

When the advanced functionality of this library is used on a Teensy 4.1, requests are never handled and time out.
It also stops going trough the loop until the request is cancelled.

Steps to Reproduce

  1. Setup EthernetWebServer with advanced functions, like in AWS-example
  2. Run it on a Teensy 4.1
  3. Call the webpage

Expected behavior

Teensy sending "Hello World" as a response.

Actual behavior

The request is never handled by Teensy.

Serial Output

10.0.0.3
..........

Code used for testing

#include <EthernetWebServer.h>
#include <NativeEthernet.h>

#define _ETHERNET_WEBSERVER_LOGLEVEL_ 4
#define USE_NATIVE_ETHERNET true
#define USE_THIS_SS_PIN 10

byte mac[6] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};

IPAddress ip(10, 0, 0, 3);
IPAddress gateway(10, 0, 0, 1);
IPAddress submask(255, 255, 255, 0);

EthernetWebServer server(80);

void setup()
{
    Serial.begin(115200);
    while (!Serial)
        ;

    Ethernet.init(USE_THIS_SS_PIN);
    Ethernet.begin(mac, ip, gateway, submask);

    Serial.println(Ethernet.localIP());

    server.on("/", []()
              { server.send(200, "text/html", "Hello World"); });

    server.onNotFound([]()
                      { server.send(404, "Content not found"); });

    server.begin();
}
int lastBeat = 0;
void loop()
{
    if (millis() - lastBeat >= 5000)
    {
        Serial.print(".");
        lastBeat = millis();
    }
    server.handleClient();
}

FNET dns-client (on Teensy 4.1) doesn't resolve hostnames of Azure Table Storage accounts

This is not an issue of this library but of the FNET library used by the NativeEthernet library on Teensy 4.1.
I'm just searching for people to take part in the discussion whether this is an issue of the FNET library or not.

butok/FNET#7

https://stackoverflow.com/questions/67421802/should-rfc-conform-dns-clients-resolve-urls-of-azure-table-storage-accounts-whic

On the first I would be happy if someone could confirm that on the Teensy 4.1 FNET doesn't resolve the Ip addresses of CNAME records.
Kind regards
