How To Install Using Arduino Library Manager
Many people, me including, are using Arduino, Teensy, etc. boards with ESP8266 AT-Command shields, which present many problems and limitations, such as small 2K AT-command buffer size, slow speed, unreliability, etc.
The introduction of new and much more powerful dual-cored ESP32-based WiFi/BT/BLE Modules/Shields (such as U-Blox WiFiNINA, W101, W102), has been well received and already implemented and used in Nano-33-IoT, Nano-33-BLE, etc.
However, the library support is still not as complete as that of ESP8266/ESP32.
That’s why we, so far, still haven’t got libraries similar to ESP8266WebServer, WiFiManager for Arduino, Teensy, etc. using this U-Blox WiFiNINA modules/shields.
This is the reason for me to finish this new WiFiWebServer library. The WiFiNINAManager and BlynkWM_WiFiNINA for boards such as Nano-33-IoT, SAMD21, SAMD51, Teensy, STM32, etc. will be in the to-do list.
This is simple yet complete WebServer library for AVR, Teensy, SAM DUE, SAMD, STM32, etc. boards running WiFi modules/shields (WiFiNINA U-Blox W101, W102, etc.). The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32.
The library currently supports these boards
1. SAM DUE
2. SAMD21 (ZERO, MKR, Nano-33-IoT, M0, M0 Pro, AdaFruit CIRCUITPLAYGROUND_EXPRESS, etc.)
3. SAMD51 (Adafruit M4 : Metro, Grand Central, ItsyBitsy, Feather Express, Trellis, Metro AirLift lite, MONSTER M4SK Express, Hallowing Express, etc. )
4. Teensy (4.0, 3.6, 3.5, 3,2, 3.1, 3.0, LC)
5. STM32F1, STM32F2, STM32F4, STM32F7
The library supports
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.
Library is based on and modified from:
1. Ivan Grokhotkov's ESP8266WebServer
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 simultaneous client.
This is the HelloServer example
