Important notes about Portenta_H7 Ethernet

Portenta_H7 Ethernet doesn't work in mbed_portenta core v3.0.0, and has been fixed in core v3.0.1. Check [Portenta_H7] Ethernet not working in core v3.0.0 #436.

Please use mbed_portenta core v2.8.0- or v3.0.1+ for Portenta_H7 Ethernet.

Why do we need this WebSockets_Generic library

Features

Many Web services require WebSockets library, which is so far written only for ESP8266/ESP32 boards. The ESP boards rely on this Markus Sattler's WebSockets Library to connect to Alexa via Sinric or SinricPro skills.

This WebSockets_Generic library is a RFC6455-based WebSocket Server and Client for Arduino boards. It is based on and modified from Markus Sattler's WebSockets Library to provide support to many more boards, such as WT32_ETH01 (ESP32 + LAN8720), Arduino SAMD21, Adafruit SAMD21/SAMD51, nRF52, STM32F/L/H/G/WB/MP1, Teensy, SAM DUE, RP2040-based boards, etc. and enable those boards to use WebSockets services, including voice-control Alexa along with Blynk. Those supported boards can also run WebSockets Server. The WebSockets can be used with ESP’s WiFi, WiFiNINA, WiFi101, W5x00, ENC28J60 Ethernet and Teensy 4.1 NativeEthernet/QNEthernet.

Supported features of RFC6455

  • text frame
  • binary frame
  • connection close
  • ping
  • pong
  • continuation frame

Important Notes

  1. Currently, the WebSocketServer feature is usable only for ESP8266/ESP32 (ESP32, ESP32_S2, ESP32_S3 and ESP32_C3) and WT32_ETH01 (ESP32 + LAN8720).
  2. The timeline when to fix and reintroduce the WebSocketServer feature to other boards is not determined yet.
  3. Please use the new WebSockets2_Generic Library if WebSocketServer is necessary. See Issue 2, Issue 3 and Issue 4

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

SUBSYSTEMS=="usb", ATTRS{idVendor}=="2341", ATTRS{idProduct}=="035b", GROUP="plugdev", MODE="0666"

Supposing the ArduinoCore-mbed core version is 3.4.1. Now only one file must be copied into the directory:

  • ~/.arduino15/packages/arduino/hardware/mbed_portenta/3.4.1/portenta_post_install.sh

Whenever a new version is installed, remember to copy this files into the new version directory. For example, new version is x.yy.zz

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

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 Notes

  1. Code is restructured to provide flexibility to make it easy to support many more WiFi/Ethernet modules/shields in the future. Please delete the *.cpp files, replaced by *.hpp files, in the src directory, if *.cpp files still exist after installing new version.

  2. For Adafruit nRF52, use the SPI's pin as follows:

  • SS/CS = 10
  • SPI_MOSI = MO(SI)
  • SPI_MISO = MI(SO)
  • SPI_SCK = SCK
  1. For Adafruit SAMD21/SAMD51, use the SPI's CS/SS pin as follows:
  • Itsy-Bitsy M0/M4, Feather M0 (Express), Hallowing M0 Express, Zero, Metro M0 => use CS = 16 = pin A2
  • Feather M4 (SAMD51) => use SS/CS = 9
  • Grand Central M4 => use SS/CS = 53
  • Hallowing M4 => use SS/CS = 10
  • Metro M4 AirLift => use SS/CS = 36

To know the default CS/SS pins of not listed boards, check the related variant.h files in

~/.arduino15/packages/adafruit/hardware/samd/x.y.zz/variants/board_name/variant.h

  1. For Arduino SAM DUE, use the SPI's pin as follows:

Limitations

  • max input length is limited to the ram size and the WEBSOCKETS_MAX_DATA_SIZE define
  • max output length has no limit (the hardware is the limit)
  • Client send big frames with mask 0x00000000 (on AVR all frames)
  • continuation frame reassembly need to be handled in the application code

Limitations for Async

  • Functions called from within the context of the websocket event might not honor yield() and/or delay(). See this issue for more info and a potential workaround.
  • wss / SSL is not possible.

wss / SS

supported for:

  • wss client on the ESP8266
  • wss / SSL is not natively supported in WebSocketsServer. However it is possible to achieve secure websockets by running the device behind an SSL proxy. See Nginx for a sample Nginx server configuration file to enable this.

ESP Async TCP

This library can run in Async TCP mode on the ESP.

The mode can be activated in the WebSockets_Generic.h (see WEBSOCKETS_NETWORK_TYPE define).

ESPAsyncTCP library is required.

How to use

In your code, select one of the currently supported network connection from the following list:

  1. NETWORK_ESP8266_ASYNC for ESP8266 Async
  2. NETWORK_W5100 for W5x00 Ethernet
  3. NETWORK_ENC28J60 for ENC28J60 Ethernet using UIPEthernet library
  4. NETWORK_ESP32 for ESP32 WiFi
  5. NETWORK_ESP32_ETH for ESP32 Ethernet
  6. NETWORK_WIFININA for WiFiNINA
  7. NETWORK_ETHERNET_ENC for ENC28J60 Ethernet using EthernetENC library
  8. NETWORK_RTL8720DN for NETWORK_RTL8720DN Ethernet using Seeed_Arduino_rpcWiFi and Seeed_Arduino_rpcUnified libraries
  9. NETWORK_NATIVEETHERNET for Teeensy 4.1 NativeEthernet
  10. NETWORK_LAN8742A for STM32 with LAN8742A Ethernet using STM32Ethernet library
  11. NETWORK_WIFI101 for SAMD_MKR1000 and SAMD_MKRWIFI1010 using WiFi101 library
  12. NETWORK_QN_ETHERNET for Teeensy 4.1 built-in Ethernet using QNEthernet Library
  13. NETWORK_PORTENTA_H7_WIFI for Portenta_H7 using Murata WiFi
  14. NETWORK_PORTENTA_H7_ETHERNET for Portenta_H7 using Vision-shield Ethernet
  15. NETWORK_ESP32_ASYNC for ESP32 using Async WebSockets
  16. NETWORK_RP2040W_WIFI RP2040W using CYW43439 WiFi with arduino-pico core

then add #define WEBSOCKETS_NETWORK_TYPE before #include <WebSocketsClient_Generic.h>

For example:

#define WEBSOCKETS_NETWORK_TYPE   NETWORK_WIFININA

#include <WebSocketsClient_Generic.h>

Troubleshooting

If you get compilation errors, more often than not, you may need to install a newer version of the board's core, dependent libraries or this library version.

Sometimes, the library will only work if you update the core to the newer or older version because some function compatibility.

websockets_generic's Issues

Websockets Disconnects after first message recieved ESP32 Generic Ethernet WS5

Describe the bug

Using the standard example for Websockets2 Generic, and ESP32 with WZ500 shield as a WebsocketServer, everything works, excepts after first message the server closes the websocket.

Steps to Reproduce

Compile and run the WebsocketServer Example under Generic, ESP32 Ethernet.

Expected behavior

Like with normal Websockets library Links2004
the socket should stay open until client disconnects or server kills the connection.

Actual behavior

Server sends disconnect after first message received.

Information

Please ensure to specify the following, or your post will be ignored and deleted:

This happens on any IDE, PlatformIO and Ardunio IDE.
Using latest espressif32, with platform arduino.
Nothing added, plain example. Tested from Chrome and several other browsers.

This happens on Wifi and Ethernet.

Problem with connecting to a nodejs (socket.io)

Hello Khoih,

The library must have a problem.
Remember that I told you that sometimes, when restarting the servers, the mkr 1000 with ethernet shield and with your library, socket.io could not reconnect with the server, and the only way to make it work again was to turn off the arduino and restart it.
You told me that the problem was the fault of nodejs on ubuntu.
But now I am using the mkr1000 over wifi (wifi101) and the nodejs server is on Windows and I have exactly the same problem, so undoubtedly, the library must have some problem, and in certain circumstances it cannot reconnect with the server.
This is a serious problem and makes your library unusable in an environment that requires connection security.
The difficulty here is the reproduction of this problem, as it occurs at some point, it can happen a few hours or occur immediately, sometimes restarting the server, other times without doing anything special.
It's very complicated.
Do you have any idea to solve it?

Thanks for the help.
Hope you're well.

Regards,
Jose.

SocketIO re-connect does not work

Describe the bug

Using several boards (such as the RP2040 Connect or the MKRWiFi1010) on a WiFi connection (i.e. no Ethernet-shield but pure WiFi), I had to realize that this library's SocketIO re-connect does not work.

Steps to Reproduce

Using a remote Node.js Server (cannot share since our customer does not allow), I made the following observation:

(by the way, very similar to this issue explained here - unfortunately no solution was posted about this issue yet)

  • The remote SocketIO server turns off and turns on
    --> this should lead to a SocketIO re-connect on the Arduino client. But it doesn't !
    --> As a background information: Our remote SocketIO server must be able to turn off and turn on since it is hosted in our case as a Google Cloud Run server. And any Node does disconnect after a maximum time of 3600 seconds (security policy). Therefore we must solve this re-connect issue with the WebSocket_Generic library using SocketIO)

  • For my trials here, I put the remote-server turn off and back-on period to 60 seconds. This gives me many more occasions to observe the Arduino behaviour.

  • So, the remote SocketIO server continues turning off and back on - every 60 seconds. And I can observe that the Arduino's SocketIO DISCCONNECT event is only occurring sporadically (i.e. about every 2nd or 3rd time). This is a wrong and inexplicable behaviour.

Steps to reproduce:

  • turn off and turn on the remote SocketIO server
  • the Arduino Serial Monitor stops showing ping/pong (in fact, it does not show anything after the remote-server turns off/on). It is in an unknown state.
  • the Arduino does not re-connect as it should. It does not even show any kind of SocketIO event (such as DISCONNECT, CLOSE, not any EVENT happens).

Expected behavior

The expected behaviour is that the Arduino SocketIO Client re-connects automatically.

This behaviour is the standard behaviour of Socket IO as described here and here.

Not sure if important - but on the official Socket.io page, it sais Please note that since Socket.IO v3, the Socket instance does not emit any event related to the reconnection logic anymore. You can listen to the events on the Manager instance directly:

socket.io.on("reconnect_attempt", () => {
  // ...
});

socket.io.on("reconnect", () => {
  // ...
});

One more observation:

I am using WiFi to connect. (RP2040 Connect or MKRWiFi1010) and I am using beginSSL(...) to connect with SocketIO.

All that works fine.

Now, when I turn off my WiFi network, I do get a DISCONNECT event inside the Arduino Client.

But I do not get this event when the remote-server turns its node off.

Nano IOT and platform IO "Communication with WiFi module failed!"

Hello,
When running any example on different Nano IOT I noticed that when using platform io you always end up with the message "Communication with WiFi module failed!". This seems to only happen on platform io because the example i used work on arduinoIDE 2.0

The problem seems to be coming from WIFI NINA generic.

To solve this i ended up modifying the #include <WiFiNINA_Generic.h> by <WiFiNINA.h> in WebSockets_Generic.h

PS: you also need to add lib_ignore = DueFlashStorage in platformio.ini to remove a bunch of error when adding the lib to the project

Compile error on Wio Terminal: 'class WiFiClientSecure' has no member named 'setInsecure'

Hi,
I'm just updating a 'Sinric Pro' application for the Wio Terminal from the lib SinricPro_Generic v2.8.0 to v2.8.3 and now get the compilation error from the included WebSockets_Generic library:
.pio\libdeps\SAMD\WebSockets_Generic@src-3e25c04322622ed35619bd8f1cb33dbd\src/WebSocketsClient_Generic-Impl.h:396:22: error: 'class WiFiClientSecure' has no member named
'setInsecure'
_client.ssl->setInsecure();

It's not a big thing and not really a problem for me, but I think that it should not occur and I only wanted to inform about the issue.

PlatformIo Home v3.4.0
Board: Seeed Wio Terminal

Btw: Again many thanks for your valuable work. Lately I used your 'ESPAsync_WiFiManager' in an application (https://github.com/RoSchmi/Esp32_WiFiManager_HeatingSurvey) and it works like a charm.

Best regards

Ability to receive the Response HTTP Headers

I see that HTTP headers are populated somewhere in the deep of the library. But from client's side they are not available. Most of them are just technical. But one of the interests is sec-websocket-protocol.
Because as described in RFC 6455 client can send a few desired protocols and the server may choose one of them. But client can not get information on what protocol was chosen by the server.

So it would be really helpful to have a kind of .getHeaders() or similar public method on the WebSocketsClient to get this information or it can be passed back to onWsEvent callback alongside with type, payload and length.

Compatibility with WiFiMulti

Hello,

We're developing an embedded application based on the Pico 2040W and are running the maxgerhardt platform with the earlephilhower Arduino Core with WiFiMulti for connectivity. The wireless connection works as intended but we're having troubles establishing a WebSocket connection to our FastAPI server.

}

The code runs, but I never reach a state where it prints anything, and when I check webSocket.isConnected() it returns false. My question is – could this have to do with our Wi-Fi library, or simply because it's unable to connect?

The websocket endpoint is currently hosted on a local device at 192.168.1.212:8000/ws({device_id}. I'm able to connect to this endpoint just fine using Postman or other Websocket programs, but not through this library.

Any help is greatly appreciated! ❤️

Thanks,
Jonathan

It continues like that until arduino ide just crashes.
I'm not even trying to connect another device at this point, cos i can't.
Can you please help with this issue? I found this library has a lot of potential but i can't use it. Or maybe i can contribute if you point me in the right direction, thanks.

I need to use ESP32 as a websocket over ethernet without wifi.
The environment cannot use wifi.
I need a websocket connection from my laptop to ESP32 via ethernet.
How can this be possible?
Even if I try to change the example, the server is connected and the web page is loaded, but the websocket cannot be connected.

Thank you in advance.

ESP32 + W5500 Test example

Hello, thank you for your efforts in creating this library
My project uses the ESP32 + W5500 module and the Websocket protocol.
I'm looking to use your library but it's confusing to me.
Which WebSockets2_Generic or WebSockets_Generic exactly?
Which ethernet Libraries should be selected ?! Ethernet2.h or EthernetLarge.h
Also, which example should be tested? Is there a roadmap?

thank you

No free space new client / Counting of clients wrong?

Try to setup a web socket server with wifinina.

When I try the example Generic_WebSocketServer_WiFiNINA.ino the
websocket connection is always closed. I try to connect with different clients.
As far I can see the MKR WiFi 1010 should be supported since version 2.1.3.

It looks for me that the counting of the clients is not correct. I try to open only
one connection. See the log.

Wifi-version:

Loss of connection of the arduino MKR with the nodejs server when the nodejs server is restarted.

Hello Khoih,

We haven't spoken for a long time, I hope you are feeling very well.

I have a serious problem with socket.io, as you know I am using nodejs as a server and an Arduino MKR1000.
I have observed the following bug, when I turn off the nodejs and then run it, an automatic reconnection of the arduinos to the nodejs generally occurs, however, this does not always happen, on many occasions, the arduino does not reconnect with the nodejs server and I have no choice but to turn the arduinos power off and turn them back power on.
I also have a web application created with Flutter and that uses socket.io that does not have this problem, so it is obviously a problem with the websockets_generic library.
Would you have any idea how to solve this problem?

Thank you very much for your help.

Regards,
Jose A.Molina

Just wondering how exactly the client will receive the event from the socket.io server.

Hey Khoi!

Cheers for helping me earlier, I got it working now, seemed to be an issue with how I portfowarded of sorts. Not really an issue here just need clarification. I am quite new to arduino and this might seem obvious, but im having a bit of a hard time understanding how exactly.

Say my server is emitting the event.

io.emit("Event", ("Hello World!"))

Which one of the arguments should I use to get it to print out the event? From what I've seen you need the call the event before you declare it on the ESP32 side, this got my bewildered as a normal client on socket.io doesnt declare the event before it happens. In the documentation I saw these two referred:

void (*WebSocketClientEvent)(WStype_t type, uint8_t * payload, size_t length)

And

void onEvent(WebSocketClientEvent cbEvent);

Callback is the data of the event right? Which one of these two would you use for it to detect the event named "Event" and for it to print the "Hello World!" string, and how does the client know which event to respond to. On sockets.io when you program a client tradionally you simply just use the socket.io function

Cheers and thanks in advance, I'm sorry is this is a stupidly obvious question.

WT32-ETH01 connects for about 90 seconds then suddenly disconnects, cant figure out why.

I am absolutely bewildered right now, I have been using this library WebSocket_generic for my WT32-ETH01 and ive been using its examples just to check for a connection. Ive used both the server and client examples, it connects just fine, but after three messages, or roughly 90 secs give or take it suddenly and abruptly disconnects. Give it 5 minutes it reconnects, sends some more pings and it disconnects, and does so in a cycle. Here is the serverside code:

Server side code:

io.on('connection', (socket) => {

  console.log('Connected');
  console.log(socket.id);
  console.log("JWT token test: ",socket.handshake.headers)

  socket.on('event_name', (data) => {

    console.log("Message from Client : ", data);

    socket.broadcast.emit("Send Message socket.broadcast.emit : ", data);
    io.emit("Send Message io.emit Broadcasted : ", data);
    socket.emit("Send Message : ", data);

  })
  
  socket.on('disconnect', (reason) => {

    console.log('Disconnected');
    console.log(reason);

  })

})



http.listen(8080, () => {

  console.log("Server launched on port 8080");
})

I am lost, ive used different socket.io verisions such as v1, v2, v3 and v4.

What I expect to happen is for it to have a stable connection, it connects but it disconnects after a short while.

RX:HTTP/1.1 400 Bad Request

hello,

First of all, I would like to thank you for creating such a great library.
Using this library, I am getting RX:HTTP/1.1 400 Bad Request from the server.

I am using DOIT ESP32 DEVKIT VERSION1
IDE: Arduino IDE version: 1.8.16
to experiment the socket IO communication, I used your library. From your library I burnt the code for server into one of the esp32 and obtained its IP address
I used another esp32 and burnt the websocketclientsocketIOack code with changes in the servers' IP address. (The IP address of my server ESP32)
after burning this client code into another esp32, this client esp32 try to connect with the server esp32.
from the serial monitor of server esp32, its showing me [0]Disconnected.
from the serial monitor of client esp32, its displaying me client information along with server response.
in the server response, I see this RX:HTTP/1.1 400 Bad Request

I am unable to understand what mistake is happening.

Another try I made is to connect with another socket IO server which was created using DJANGO framework.
and its response is as below.

Run websocket only mode for Socket.IO

Is there a way to run "websocket" only mode with Socket.IO on this Arduino library ?

I made a local Socket.IO client that works well with the WebSockets_Generic Example "WiFiNINA-->WebSocketClientSocketIO_NINA" - but only if the server has "transport=["polling", "websocket"]," defined.

If I change the server to "transport=["websocket"]," then it does not work anymore.

However, our application absolutely requires "websocket only" configuration !

On other Socket.IO clients there is a possibility to force to "websocket only".
For example in the iOS-client there is a config setting called ".forceWebsockets(true)," that makes exactly that.

The keyword, I think, is called "websocket only". Please refer to the Socket.IO documentation here and the error you get if websocket only is missing is explained here

Is there a "websocket only" mode for the WebSockets_Generic library ?
If yes, how would I configure it ?

Support as Http server and the Websockets server on Arduino DUE

Hello,
Sorry i want so talk about Websockets Server Examples.

i am want wo work with the library with Arduino DUE and PlatformIO last version from Today.
My projectis based on AJAX now i want to switch some functions to Websockets.
I have an working Webserver with html files on SDCard, and i want to bring these Library as websock server on the DUE. Normal Ethernet shiled with the WizNet 5100 controller and SDslot.

Is this posible ?
The PC ist only the client and the DUE is the Server for http and Websock paralel.
The Due sends the data to the Client Browser on the pc.

I havent seen an Examble as Server also not found realy the DUE as suppotert, well only the list for the toolchain.

WebSocketsClient still reconnects after calling .disconnect()

Describe the bug

Can't find any info in the docs. So asking here:
There is .setReconnectInterval() method for specifying a reconnection interval. And there is a .disconnect() method.

I was assuming that automatic reconnection happens only on network errors. And if the client explicitly calls .disconnect() - no reconnections should occur after that. But for now, the client is still reconnecting.

Is this an expected behaviour? Or it is a bug? And how to disconnect?

multiple definition of `WebSocketsClient::*`

Describe the bug

Hi there! First of all, thnx for your library!

I'm implementing another library that relies on this one. So to be able to use objects and methods from this library I had exactly one include of this library in my main header file.
Something like this in mylibrary.h

#include <WebSocketsClient_Generic.h>

I also have a mylibrary.cpp with again has exactly one include of its header:

#include "mylibrary.h"

Now I'm making an arduino sketch (ino) where I include only my library header. Something like this:

#include <mylibrary.h>

I'm trying to compile the sketch and am getting a bunch of errors about multiple definitions:

Actually compilation succeeds, but the linking stage — not :(

I am using ESP32 DOIT ESP32DEVKIT V1 board but i suppose that doesn't matter.
Test examples of the library works as expected.

So why is it happening? Am i doing something wrong? Can you advice?
Thnx!

Ethernet with SSL

I am trying to connect to a Socket.IO server with Ethernet and SSL.

The Board: MKR WiFi1010
The Ethernet Shield: MKR ETH stacked on top of the MKR WiFi1010

I was thinking of using the EthernetWebServer_SSL library.

EthernetClient client;
EthernetSSLClient sslClient(client, TAs, (size_t)TAs_NUM);

However, I do not see a way on how to achieve the connection with the SocketIO client.

SocketIOclient socketIO;

Obviously, in my code there is no SSL connection yet. And therefore the connection does not work as can be seen in the following log:

Connected! My IP address: 192.168.1.65
Connecting to WebSockets Server @ IP address: test.test.com, port: 443
[WS] WebSockets_Generic v2.11.1
[WS] [wsIOc] found EIO=4 disable EIO ping on client
[WS] [WS-Client] Connect wss...
Receiving Payload:

[IOc] Disconnected
[WS] [wsIOc] Disconnected!

Below is my entire code. The SSL-certifcate is placed in the trust_anchors.h file as described in the EthernetWebServer_SSL library.

Questions:

  1. How do I link the sslClient to the socketIO client correctly ? Or is this the wrong way at all ?

  2. How would I achieve SSL and Ethernet with the WebSocket_Generic's Socket.IO library ?

  3. Is the call to socketIO.beginSSL(server, serverPort); automatically doing SSL ? Or is there something missing ? How do I achieve SSL with Socket.IO ?

Thanks.

Ping events propagated to main code socketIO events

Is your feature request related to a problem? Please describe.

Using SocketIO with your library, I could really use the "ping"/"pong" events in the main code to detect when I am off internet.

One application of this feature-request is to trigger my watchdog timer in my Arduino board. If, for some reason, the internet is off then the Arduino board would get restarted.

Describe the solution you'd like

In order to make the above feature work, all we have to add is the following:
(of course not knowing if you have an even better solution to this - if you do, please let me know....)

Inside SocketIOclient_Generic.h file, you can add an event enum (see last line case 7):

typedef enum
{
  sIOtype_CONNECT      = '0',
  sIOtype_DISCONNECT   = '1',
  sIOtype_EVENT        = '2',
  sIOtype_ACK          = '3',
  sIOtype_ERROR        = '4',
  sIOtype_BINARY_EVENT = '5',
  sIOtype_BINARY_ACK   = '6',
  sIOtype_PING         = '7',
} socketIOmessageType_t;

And inside SocketIOclient_Generic-Impl.h file, you can add one line of code to "deviate" the ping to the events-listener in the main code (please not the extra line with runIOCbEvent(sIOtype_PING, payload, length);)

case eIOtype_PING:
  payload[0] = eIOtype_PONG;
  
  WSK_LOGWARN1("[wsIOc] get ping send pong:", (char *) payload);
  
  WebSocketsClient::sendTXT(payload, length, false);            
  runIOCbEvent(sIOtype_PING, payload, length);
  
  break;

This allows in the main code:

void socketIOEvent(socketIOmessageType_t type, uint8_t* payload, size_t length) {
  
    // switch socketIO events
    switch (type) {

        case sIOtype_PING:
            /* PING */
            watchdog.kick();

            break;
    // ...
    }
}

Additional context
I tried to make a pull-request with this but the appropriate permissions are not available.

Feel free to implement the above solution if you find it helpful for others. Thank you.

Arduino Portenta not connect to SocketIO example

Arduino Portenta not connect to SocketIO example

I'm trying to connect a Arduino Portenta as SocketIO client to the SocketIO server example in this repo and it keeps disconnecting. After a few tries a check if the problem was the portenta or the library so I ran the same example with a ESP-32 and a ESP-8266 and both works but when I try with Portenta keep Disconnecting and it's weird becuase in the Server logs never shows a connection but with ESP32 or ESP8266 shows each time that a client is Connected.
