This is simple yet complete WebServer library for AVR, Teensy, SAM DUE, SAMD, STM32, etc. boards running ESP8266/ESP32 AT-command shields. The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32.

The library supports:

WiFi Client, STA and AP mode
TCP Server and Client
UDP Server and Client
HTTP Server and Client
HTTP GET and POST requests, provides argument parsing, handles one client at a time.
UDP Multicast and Broadcast.

Library is based on and modified from:

The ESP8266_AT_Web_Server class found in ESP8266_AT_Web_Server.h header, is a simple web server that knows how to handle HTTP requests such as GET and POST and can only support one simultaneous client.

Test before using different AT-Firmware Version at your own risks. Just use any simple example to verify if the AT-firmware is OK.
Compatible AT-Firmare version will be updated. Check for all supported AT Firmwares and download them from AT_Firmwares.
Support to ESP32-AT-command shields has been added to permit using new library ESP_AT_Lib to replace Blynk's BlynkESP8266_Lib. The same ESP_AT_Lib can also be use for ESP8266-AT shields.

~/.arduino15/packages/adafruit/hardware/nrf52/0.21.0/cores/nRF5/Udp.h

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/adafruit/hardware/nrf52/x.yy.z/platform.txt
~/.arduino15/packages/adafruit/hardware/nrf52/x.yy.z/boards.txt
~/.arduino15/packages/adafruit/hardware/nrf52/x.yy.z/variants/NINA_B302_ublox/variant.h

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/stm32/1.9.0). 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 1.9.0. These files must be copied into the directory:

~/.arduino15/packages/STM32/hardware/stm32/1.9.0/variants/NUCLEO_F767ZI/variant.h for Nucleo-144 NUCLEO_F767ZI.
~/.arduino15/packages/STM32/hardware/stm32/1.9.0/variants/NUCLEO_L053R8/variant.h for Nucleo-64 NUCLEO_L053R8.

// Credits of [Miguel Alexandre Wisintainer](https://github.com/tcpipchip) for this simple yet effective method
// For some STM32, there is only definition of Serial in variant.h, and is used for Serial/USB Debugging
// For example, in Nucleo-144 F767ZI original variant.h
//
// #define SERIAL_PORT_MONITOR     Serial
// #define SERIAL_PORT_HARDWARE    Serial
//
// To use ESP8266/ESP32-AT, we need another Serial, such as Serial1
// To do this, first, in corresponding variant.h, modify as follows:

// #define SERIAL_PORT_HARDWARE    Serial1
//
// then assign pins D0 = RX/D1 = TX to be Hardware Serial1 by putting in sketch as follows:
//
// #define EspSerial      SERIAL_PORT_HARDWARE    //Serial1
// HardwareSerial         Serial1(D0, D1);

// This must be included in defines.h for each board you'd like to use ESPSerial as Serial1

Screen Shots

1. SAMD51 Itsy-Bitsy M4

This is the screen shot when running example AdvancedWebServer on Adafruit SAMD51 Itsy-Bitsy M4 board using this ESP8266_AT_WebServer Library

2. STM32 Nucleo-144 NUCLEO_F767ZI

This is the screen shot when running example AdvancedWebServer_STM32 on STM32 Nucleo-144 NUCLEO_F767ZI board using this ESP8266_AT_WebServer Library

3. nRF52 Itsy-Bitsy nRF52840

This is the screen shot when running example AdvancedWebServer on Adadruit nRF52840 Itsy-Bitsy board using this ESP8266_AT_WebServer Library

4. Seeeduino SEEED_XIAO_M0

This is the screen shot when running an example using UDP Multicast on Seeeduino SEEED_XIAO_M0 board using this ESP8266_AT_WebServer Library. The UDP MUlticast is used to manage Internet Gateway's Port Forwarding so that we can access from WAN, port 5990, the WebServer running in LAN, port 5990.

New Release v1.1.1

Add support to PROGMEM-related commands, such as sendContent_P() and send_P().
Update Platform.ini to support PlatformIO 5.x owner-based dependency declaration.
Clean up code. Use FlashString and related functions extensively in code as well in examples.
Enhance examples.

New in v1.1.0

Add support to UDP Multicast. Now ESP8266/ESP32 AT-command shields can run uPnP libraries to manage Internet Gateway's port forwarding.
Fix bugs.
Enhance debug support.

New in v1.0.12

Add sample Packages_Patches for STM32 (Nucleo-144 NUCLEO_F767ZI, Nucleo-64 NUCLEO_L053R8)

Version v1.0.1

Add support to server's lambda function calls with dependency on Functional-VLPP library

Initial Version v1.0.0

This is simple yet complete WebServer library for AVR, Teensy, etc. boards running ESP8266 AT-command shields. The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32.

The library supports:

WiFi Client, STA and AP mode
TCP Server and Client
UDP Server and Client
HTTP Server and Client
HTTP GET and POST requests, provides argument parsing, handles one client at a time.
UDP Multicast and Broadcast.

TO DO

Bug Searching and Killing
Add SSL/TLS Client and Server support
Support more types of boards using ESP8266 AT-command shields.
Add mDNS features.

DONE

Add support to Arduino SAMD21 (ZERO, MKR, NANO_33_IOT, etc.)
Add support to Adafruit SAMD21 (Itsy-Bitsy M0, Metro M0, Feather M0 Express, etc.).
Add support to Adafruit SAMD51 (Itsy-Bitsy M4, Metro M4, Grand Central M4, Feather M4 Express, etc.).
Add support to Adafruit nRF52 ( Feather nRF52832, nRF52840 Express, BlueFruit Sense, Itsy-Bitsy nRF52840 Express, Metro nRF52840 Express, NINA_B302_ublox, NINA_B112_ublox, etc.).
Add support to SAM DUE.
Add support to ESP32-AT
Add support to W600 and WIS600-01S
Add support to all STM32F/L/H/G/WB/MP1
Add support to Seeeduino SAMD21/SAMD51 boards (SEEED_WIO_TERMINAL, SEEED_FEMTO_M0, SEEED_XIAO_M0, Wio_Lite_MG126, WIO_GPS_BOARD, SEEEDUINO_ZERO, SEEEDUINO_LORAWAN, SEEED_GROVE_UI_WIRELESS, etc.)
Add UDP Multicast feature.
Add PROGMEM and FlashString related commands such as sendContent_P() and send_P(), and use in examples.

Contributions and Thanks

Based on and modified Ivan Grokhotkov's ESP8266WebServer
Based on and modified from bportaluri's WiFiEsp library
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. Also see U-BLOX NINA B302/ENC28J60 wth Alexa/SinricPro.
