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

2. For Teensy boards

To be able to compile and run on Teensy boards, you have to copy the files in Packages_Patches for Teensy directory into Teensy hardware directory (./arduino-1.8.19/hardware/teensy/avr/boards.txt).

Supposing the Arduino version is 1.8.19. These files must be copied into the directory:

• ./arduino-1.8.19/hardware/teensy/avr/boards.txt
• ./arduino-1.8.19/hardware/teensy/avr/cores/teensy/Stream.h
• ./arduino-1.8.19/hardware/teensy/avr/cores/teensy3/Stream.h
• ./arduino-1.8.19/hardware/teensy/avr/cores/teensy4/Stream.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 These files must be copied into the directory:

• ./arduino-x.yy.zz/hardware/teensy/avr/boards.txt
• ./arduino-x.yy.zz/hardware/teensy/avr/cores/teensy/Stream.h
• ./arduino-x.yy.zz/hardware/teensy/avr/cores/teensy3/Stream.h
• ./arduino-x.yy.zz/hardware/teensy/avr/cores/teensy4/Stream.h

3. For Arduino SAM DUE boards

To be able to compile and run on SAM DUE boards, you have to copy the whole SAM DUE directory into Arduino sam directory (~/.arduino15/packages/arduino/hardware/sam/1.6.12).

Supposing the Arduino SAM core version is 1.6.12. This file must be copied into the directory:

• ~/.arduino15/packages/arduino/hardware/sam/1.6.12/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/arduino/hardware/sam/x.yy.zz/platform.txt

4. For Arduino SAMD boards

To be able to compile, run and automatically detect and display BOARD_NAME on Arduino SAMD (Nano-33-IoT, etc) boards, you have to copy the whole Arduino SAMD Packages_Patches directory into Arduino SAMD directory (~/.arduino15/packages/arduino/hardware/samd/1.8.13).

For core version v1.8.10+

Supposing the Arduino SAMD version is 1.8.13. Now only one file must be copied into the directory:

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

These files must be copied into the directory:

• ~/.arduino15/packages/arduino/hardware/samd/x.yy.z/platform.txt
• ~/.arduino15/packages/arduino/hardware/samd/x.yy.z/cores/arduino/Arduino.h

This is mandatory to fix the notorious Arduino SAMD compiler error. See Improve Arduino compatibility with the STL (min and max macro)

 ...\arm-none-eabi\include\c++\7.2.1\bits\stl_algobase.h:243:56: error: macro "min" passed 3 arguments, but takes just 2
     min(const _Tp& __a, const _Tp& __b, _Compare __comp)

Whenever the above-mentioned compiler error issue is fixed with the new Arduino SAMD release, you don't need to copy the Arduino.h file anymore.

5. For Adafruit SAMD boards

To be able to compile, run and automatically detect and display BOARD_NAME on Adafruit SAMD (Itsy-Bitsy M4, etc) boards, you have to copy the whole Adafruit SAMD Packages_Patches directory into Adafruit samd directory (~/.arduino15/packages/adafruit/hardware/samd/1.7.11).

Supposing the Adafruit SAMD core version is 1.7.11. These files must be copied into the directory:

• ~/.arduino15/packages/adafruit/hardware/samd/1.7.11/platform.txt

7. For STM32 boards

7.1 For STM32 boards to use LAN8720

For Generic STM32F4 series boards, such as STM32F407VE, using LAN8720, please use STM32 core v2.2.0 as breaking core v2.3.0 creates the compile error.

---

To use LAN8720 on some STM32 boards

• Nucleo-144 (F429ZI, NUCLEO_F746NG, NUCLEO_F746ZG, NUCLEO_F756ZG)
• Discovery (DISCO_F746NG)
• STM32F4 boards (BLACK_F407VE, BLACK_F407VG, BLACK_F407ZE, BLACK_F407ZG, BLACK_F407VE_Mini, DIYMORE_F407VGT, FK407M1)

you have to copy the files stm32f4xx_hal_conf_default.h and stm32f7xx_hal_conf_default.h into STM32 stm32 directory (~/.arduino15/packages/STM32/hardware/stm32/2.2.0/system) to overwrite the old files.

Supposing the STM32 stm32 core version is 2.2.0. These files must be copied into the directory:

• ~/.arduino15/packages/STM32/hardware/stm32/2.2.0/system/STM32F4xx/stm32f4xx_hal_conf_default.h for STM32F4.
• ~/.arduino15/packages/STM32/hardware/stm32/2.2.0/system/STM32F7xx/stm32f7xx_hal_conf_default.h for Nucleo-144 STM32F7.

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

• ~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/system/STM32F4xx/stm32f4xx_hal_conf_default.h
• ~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/system/STM32F7xx/stm32f7xx_hal_conf_default.h

7.2 For STM32 boards to use Serial1

To use Serial1 on some STM32 boards without Serial1 definition (Nucleo-144 NUCLEO_F767ZI, Nucleo-64 NUCLEO_L053R8, etc.) boards, you have to copy the files STM32 variant.h into STM32 stm32 directory (~/.arduino15/packages/STM32/hardware/stm32/2.3.0). You have to modify the files corresponding to your boards, this is just an illustration how to do.

Supposing the STM32 stm32 core version is 2.3.0. These files must be copied into the directory:

• ~/.arduino15/packages/STM32/hardware/stm32/2.3.0/variants/STM32F7xx/F765Z(G-I)T_F767Z(G-I)T_F777ZIT/NUCLEO_F767ZI/variant.h for Nucleo-144 NUCLEO_F767ZI.
• ~/.arduino15/packages/STM32/hardware/stm32/2.3.0/variants/STM32L0xx/L052R(6-8)T_L053R(6-8)T_L063R8T/NUCLEO_L053R8/variant.h for Nucleo-64 NUCLEO_L053R8.

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

• ~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/variants/STM32F7xx/F765Z(G-I)T_F767Z(G-I)T_F777ZIT/NUCLEO_F767ZI/variant.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

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

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

• SS/CS = 10
• SPI_MOSI = 75 ( pin 4 @ ICSP connector )
• SPI_MISO = 74 ( pin 1 @ ICSP connector )
• SPI_SCK = 76 ( pin 3 @ ICSP connector )

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>

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.
