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

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

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

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

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.

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

  3. 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:

  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
    1. NETWORK_LAN8742A for STM32 with LAN8742A Ethernet using STM32Ethernet library
    2. NETWORK_WIFI101 for SAMD_MKR1000 and SAMD_MKRWIFI1010 using WiFi101 library
    3. NETWORK_QN_ETHERNET for Teeensy 4.1 built-in Ethernet using QNEthernet Library
    4. NETWORK_PORTENTA_H7_WIFI for Portenta_H7 using Murata WiFi
    5. NETWORK_PORTENTA_H7_ETHERNET for Portenta_H7 using Vision-shield Ethernet
    6. NETWORK_ESP32_ASYNC for ESP32 using Async WebSockets
    7. NETWORK_RP2040W_WIFI RP2040W using CYW43439 WiFi with arduino-pico core

2. Generic_Ethernet_Blinds on NRF52840_FEATHER with ENC28J60 using EthernetENC Library

You can see the NRF52840_FEATHER board, with ENC28J60 using EthernetENC Library, connects to SinricPro service using SinricPro_Generic library.

It also uses this WebSockets_Generic library to communicate with SinricPro service, to control Blinds via the Sinric Pro phone APP

Debug

Debug is enabled by default on Serial. To disable, add at the beginning of sketch

/* Comment this out to disable prints and save space */
#define DEBUG_WEBSOCKETS_PORT         Serial

#define _WEBSOCKETS_LOGLEVEL_         4

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.

Issues

Submit issues to: WebSockets_Generic issues

TO DO

  1. Bug Searching and Killing
  2. Support more types of boards using WiFi/Ethernet shields (Teensy, etc.)
  3. Support more non-compatible Ethernet Libraries such as Ethernet_Shield_W5200, EtherCard, EtherSia
  4. Support ASYNC mode for boards using communication libraries supporting Async (STM32, Portenta, Teensy 4.1, ESP32, etc.)

DONE

  1. Add support to Arduino SAMD21 (ZERO, MKR, NANO_33_IOT, etc.)
  2. Add support to Adafruit SAMD21 (Itsy-Bitsy M0, Metro M0, Feather M0 Express, etc.).
