Why do we need this WiFiWebServer library

Features

This WiFiWebServer library is a simple yet complete WebServer library for AVR, Portenta_H7, Teensy, SAM DUE, Arduino SAMD21, Adafruit SAMD21/SAMD51, Adafruit nRF52, ESP32/ESP8266, STM32F/L/H/G/WB/MP1, etc. boards, using WiFi modules/shields (WiFiNINA, WiFi101, U-Blox W101, W102, ESP8266/ESP32-AT, etc.).

The functions are similar and compatible to those of ESP32 WebServer and ESP8266WebServer libraries to make life much easier to port sketches from ESP8266/ESP32.

This WiFiWebServer library, from v1.1.0, also provides high-level HTTP and WebSocket Client with the functions are similar and compatible to those of ArduinoHttpClient Library

The library provides supports to:

1. WiFi Client, STA and AP mode
2. TCP Server and Client
3. UDP Server and Client
4. HTTP Server and Client
5. HTTP GET and POST requests, provides argument parsing, handles one client at a time.
6. High-level HTTP (GET, POST, PUT, PATCH, DELETE) and WebSocket Client. From v1.1.0.

It is based on and modified from:

1. Ivan Grokhotkov's ESP8266WebServer
2. Ivan Grokhotkov's ESP32 WebServer
3. ArduinoHttpClient Library

The WiFiWebServer class found in WiFiWebServer.h header, is a simple web server that knows how to handle HTTP requests such as GET and POST and can only support one client at a time.

The newly-created WiFiMulti-related examples in WiFiMulti demonstrate how to use the new WiFiMulti_Generic library to connect to the best of multi-WiFi APs, with auto-checking / auto-reconnecting features when WiFi connection is lost.

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
• ~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/variants/STM32L0xx/L052R(6-8)T_L053R(6-8)T_L063R8T/NUCLEO_L053R8/variant.h

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

How to configure to use different WiFi Libraries

1. Modify pin-to-pin connection in WiFiNINA_Generic library

Please change the pin-to-pin connection in ~/Arduino/libraries/src/WiFiNINA_Pinout_Generic.h to match actual connection if using WiFiNINA with WiFiNINA_Generic library.

For example

#elif ( defined(NRF52840_FEATHER) || defined(NRF52832_FEATHER) || defined(NRF52_SERIES) || defined(ARDUINO_NRF52_ADAFRUIT) || \
        defined(NRF52840_FEATHER_SENSE) || defined(NRF52840_ITSYBITSY) || defined(NRF52840_CIRCUITPLAY) || defined(NRF52840_CLUE) || \
        defined(NRF52840_METRO) || defined(NRF52840_PCA10056) || defined(PARTICLE_XENON) || defined(NINA_B302_ublox) || defined(NINA_B112_ublox) )

  #warning You have to modify pin usage according to actual connection for NRF528XX
  // To define pin out for WiFiNINA here

  //#define PINS_COUNT           (60u)
  //NINA
  #define NINA_GPIO0  (26u)                             //26
  #define NINA_RESETN (27u)
  #define NINA_ACK    (28u)

  #define SPIWIFI_SS       24   //PIN_SPI1_SS            //24
  #define SPIWIFI_ACK      28   //NINA_ACK               //28 
  #define SPIWIFI_RESET    27   //NINA_RESETN            //27

2. How to select which built-in WiFi or shield to use

• To use W102-based WiFiNINA, define in the sketch:

#define USE_WIFI_NINA         true

• To use built-in WiFi101 or shield:

#define USE_WIFI_NINA         false
#define USE_WIFI101           true

• To use MKR1000 with built-in WiFi101:

// Don't care false or true
#define USE_WIFI_NINA         false

• For boards other than MKR1000, to use another WiFi library with the standard WiFi.h, such as WiFiEspAT library library

#define USE_WIFI_NINA         false

• To use another WiFi library without the standard WiFi.h

For example, WiFi_XYZ library uses WiFi_XYZ.h

#define USE_WIFI_NINA         false
#define USE_WIFI_CUSTOM       true

...
//Must be placed before #include <WiFiWebServer.h>
#include <WiFi_XYZ.h>
#include <WiFiWebServer.h>

3. Important

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

Contributions and Thanks

1. Based on and modified from Ivan Grokhotkov's ESP8266WebServer
2. Thanks to good work of Miguel Alexandre Wisintainer for initiating, inspriring, working with, developing, debugging and testing. Without that, support to nRF52, especially U-Blox B302 running as nRF52840 and U-Blox B112 running as nRF52832, has never been started and finished. See u-blox nina b
3. Adrian McEwen for HttpClient Library on which the ArduinoHttpClient Library and this EthernetWebServer library are relied.
4. RQnet to report issue Decoding Error. two times called urlDecode in Parsing-impl.h. #17 leading to version v1.6.3 to fix the decoding error bug when using special & in data fields.
