WebSockets2_Generic Library

arduino-library-badge GitHub release GitHub contributions welcome GitHub issues

Donate to my libraries using BuyMeACoffee

tl;dr

Basic usage of changes for this fork, will issue a diagnostic warning #warning WEBSOCKETS_USE_GIGA_R1_WIFI in message.hpp; this is nothing to worry about.

#define WEBSOCKETS_USE_GIGA_R1_WIFI 1
#include <WiFi.h>
#include <WebSockets2_Generic.h>

As it is a header only library, can be installed without dependencies for use in this style with GIGA R1 WiFi board. Tested use of classes WebsocketsServer, WebsocketsClient, WebsocketsMessage.

Table of Contents

Why do we need this WebSockets2_Generic library

Features

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

This WebSockets2_Generic library is based on and modified from Gil Maimon's ArduinoWebSockets Library to provide support to many more boards, such as WT32_ETH01 (ESP32 + LAN8720), Arduino SAMD21, Adafruit SAMD21/SAMD51, Seeeduino SAMD21/SAMD51, nRF52, STM32F/L/H/G/WB/MP1, Teensy, SAM DUE, Portenta_H7, etc. and enable those boards to use WebSockets services, including voice-controlled 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/LAN8742A Ethernet, Teensy 4.1 NativeEthernet/QNEthernet, ESP8266/ESP32-AT modules/shields, Portenta_H7 WiFi/Ethernet, RP2040-based boards, such as Nano_RP2040_Connect, RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040, using WiFiNINA.

Please see the TinyWebsockets wiki for roughly-accurate information about the API not covered here.

8. For RP2040-based boards using Earle Philhower arduino-pico core

8.1 To use BOARD_NAME

To be able to automatically detect and display BOARD_NAME on RP2040-based boards (RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040, GENERIC_RP2040, etc) boards, you have to copy the file RP2040 platform.txt 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 into the directory:

  • ~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0/platform.txt

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 into the directory:

  • ~/.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:

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

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

just rename the following file in ./arduino-1.8.13/hardware/esp8266com/esp8266/libraries/Ethernet directory

  • From Ethernet.h to Ethernet_ESP8266.h

Note for Platform IO using ESP32 LittleFS

Necessary only for esp32 core v1.0.6-

From esp32 core v1.0.6+, LittleFS_esp32 v1.0.6 has been included and this step is not necessary anymore.

In Platform IO, to fix the error when using LittleFS_esp32 v1.0 for ESP32-based boards with ESP32 core v1.0.4- (ESP-IDF v3.2-), uncomment the following line

from

//#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */

to

#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */

It's advisable to use the latest LittleFS_esp32 v1.0.5+ to avoid the issue.

Thanks to Roshan to report the issue in Error esp_littlefs.c 'utime_p'

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:

  1. For RP2040 using Arduino mbed_rp2040 core, use the SPI's pin as follows:
  • SS/CS = 5
  • SPI_MOSI = 3
  • SPI_MISO = 4
  • SPI_SCK = 2
  1. For RP2040 using Earle Philhower's arduino-pico core, use the SPI's pin as follows:
  • SS/CS = 17
  • SPI_MOSI = 19
  • SPI_MISO = 16
  • SPI_SCK = 18

Basic Usage

Client

Creating a client and connecting to a server:

WebsocketsClient client;
client.connect("ws://your-server-ip:port/uri");

Sending a message:

client.send("Hello Server!");

Waiting for messages:

  1. Using Lambda function
// run callback when messages are received
client.onMessage([&](WebsocketsMessage message) 
{
  Serial.print("Got Message: ");
  Serial.println(message.data());
});
  1. Using normal callback function
// run callback when events are occurring
  client.onMessage(onMessageCallback);

and

void onMessageCallback(WebsocketsMessage message)
{
  //Doing something with received String message.data() type
  
  Serial.print("Got Message: ");
  Serial.println(message.data());
}

HOWTO keep receiving messages:

void loop() 
{
  client.poll();
}

Server

Creating a server and listening for connections:

WebsocketsServer server;
server.listen(8080);

Accepting connections:

WebsocketsClient client = server.accept();

// handle client as described before :)
// run callback when messages are received
client.onMessage([&](WebsocketsMessage message) 
{
  Serial.print("Got Message: ");
  Serial.println(message.data());
});

Reading WebSockets Client messages using non-blocking mode (new from v1.0.6):

Using this new feature to enable doing other tasks in the loop(), such as WebServer, control tasks, etc. Server, using library version before v1.0.6, can only read Client messages in blocking mode. Therefore, the WebSocket Server can't hang, waiting for Client, and block all other tasks from running.

  // You can do some other tasks here, such as WebServer, controlling tasks, etc.
  
  WebsocketsClient client = SocketsServer.accept();

  if (client.available())
  {
    WebsocketsMessage msg = client.readNonBlocking();

    // log
    Serial.print("Got Message: ");
    Serial.println(msg.data());

    // return echo
    client.send("Echo: " + msg.data());

    // close the connection
    client.close();
  }

Please test using one of these following new examples with v1.0.6 and v1.0.5- to see the blocking effects. Please remember to change in loop() from

WebsocketsMessage msg = client.readNonBlocking();

to

WebsocketsMessage msg = client.readBlocking();

as client.readNonBlocking() is a new function in v1.0.6+.

For Teensy 4.1 using NativeEthernet

Just as simple as:

#define WEBSOCKETS_USE_ETHERNET     true

#define USE_NATIVE_ETHERNET         true
#define USE_QN_ETHERNET             false

For Teensy 4.1 using QNEthernet

Just as simple as:

#define WEBSOCKETS_USE_ETHERNET     true

#define USE_NATIVE_ETHERNET         false
#define USE_QN_ETHERNET             true

To use ESP8266/ESP32 native WiFi

Default is using ESP8266/ESP32 native WiFi. You don't need to do anything special.

To use RP2040W built-in WiFi

#define WEBSOCKETS_USE_RP2040W            true
#define USE_RP2040W_WIFI                  true

Binary Data

For binary data it is recommended to use msg.rawData() which returns a std::string, or msg.c_str() which returns a const char*. The reason is that msg.data() returns an Arduino String, which is great for Serial printing and very basic memory handling but bad for most binary usages.

See issue #32 for further information.

SSL and WSS Support

No matter what board you are using, in order to use WSS (websockets over SSL) you need to use

client.connect("wss://your-secured-server-ip:port/uri");

The next sections describe board-specific code for using WSS with the library.

ESP8266

With the esp8266 there are multiple ways for using WSS. By default, ArduinoWebsockets does not validate the certificate chain. This can be set explicitly using:

client.setInsecure();

You can also use a SSL Fingerprint to validate the SSL connection, for example:

// To update SHA1 fingerprint, use Google Chrome to connect to https://www.websocket.org/echo.html 
// Then "View Site Information" => "Certificate Viewer" => Copy SHA1 fingerprint
// KH, This SHA1 fingerprint was updated 15.04.2021, 
// Issued on Mar 15th 2021, expired on June 13th 2021
const char echo_org_ssl_fingerprint[] PROGMEM   = "34 A2 66 08 A1 4D 1E 83 1A 0E 49 3C 4A 84 45 9E 4A 0D 08 FE";

client.setFingerprint(echo_org_ssl_fingerprint);

or you could use the setKnownKey() method to specify the public key of a certificate in order to validate the server you are connecting to.

PublicKey *publicKey = new PublicKey(public_key);
client.setKnownKey(publicKey);

or you can specify the Certificate Authority (CA) using setTrustAnchors method, as follows:

X509List *serverTrustedCA = new X509List(ca_cert);
client.setTrustAnchors(serverTrustedCA);

For client-side certificate validation, you can use RSA or EC certificates, using the method setClientRSACert or setClientECCert .

ESP32

With the ESP32 you could either provide the full certificate, or provide no certificate. An example for setting CA Certificate:

// KH, This certificate was updated 15.04.2021, 
// Issued on Mar 15th 2021, expired on June 13th 2021
const char echo_org_ssl_ca_cert[] PROGMEM = \

Debug

Debug is enabled by default on Serial. Debug Level from 0 to 4. To disable, change the _WEBSOCKETS_LOGLEVEL_ to 0

// Use this to output debug msgs to Serial
#define DEBUG_WEBSOCKETS_PORT     Serial
// Use this to disable all output debug msgs
//#define DEBUG_WEBSOCKETS_PORT
// Debug Level from 0 to 4
#define _WEBSOCKETS_LOGLEVEL_     3

Troubleshooting

If you get compilation errors, more often than not, you may need to install a newer version of the board's core, applying Libraries' Patches, Packages' Patches or this library latest version.
