Original author: khoih prog (source: https://github.com/khoih-prog/ESP8266_AT_WebServer) ## Components - **WIZnet WizFi360-EVB-Pico** x 1 ## Article #### Features This [ESP8266_AT_WebServer library](https://github.com/khoih-prog/ESP8266_AT_WebServer) is a simple yet complete WebServer library for **AVR, Teensy, SAM DUE, Arduino SAMD21, Adafruit SAMD21/SAMD51, Adafruit nRF52, STM32F/L/H/G/WB/MP1, etc. boards, using ESP8266/ESP32 AT-command WiFi modules/shields.** The functions are similar and compatible to those of [`ESP32 WebServer`](https://github.com/espressif/arduino-esp32/tree/master/libraries/WebServer) and [`ESP8266WebServer`](https://github.com/esp8266/Arduino/tree/master/libraries/ESP8266WebServer) libraries to make life much easier to port sketches from ESP8266/ESP32. 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. UDP Multicast and Broadcast. It is based on and modified from: 1.

Where to upload AT-Firmware Upload [`AT Firmware v1.7.4.0`](https://github.com/khoih-prog/ESP8266_AT_WebServer/blob/master/AT_Firmwares/AT_Firmware_bin_1.7.4.0.zip) bin files to correct locations as follows: ``` # BOOT MODE ### Flash size 8Mbit: 512KB+512KB boot_v1.2+.bin 0x00000 user1.1024.new.2.bin 0x01000 esp_init_data_default.bin 0xfc000 blank.bin 0x7e000 & 0xfe000 ### Flash size 16Mbit-C1: 1024KB+1024KB boot_v1.2+.bin 0x00000 user1.2048.new.5.bin 0x01000 esp_init_data_default.bin 0x1fc000 blank.bin 0xfe000 & 0x1fe000 ``` #### 4. Important Notes 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](https://github.com/khoih-prog/ESP8266_AT_WebServer/tree/master/AT_Firmwares). Support to ESP32-AT-command shields has been added to permit using new library [ESP_AT_Lib](https://github.com/khoih-prog/ESP_AT_Lib) to replace [Blynk's BlynkESP8266_Lib](https://github.com/blynkkk/blynk-library/releases/Blynk_Release_v0.6.1.zip). The same [ESP_AT_Lib](https://github.com/khoih-prog/ESP_AT_Lib) can also be use for ESP8266-AT shields. --- --- ## Installation ### Use Arduino Library Manager The best and easiest way is to use `Arduino Library Manager`. Search for `ESP8266_AT_Web_Server`, then select / install the latest version. You can also use this link [![arduino-library-badge](https://www.ardu-badge.com/badge/ESP8266_AT_WebServer.svg?)](https://www.ardu-badge.com/ESP8266_AT_WebServer) for more detailed instructions. ### Manual Install 1. Navigate to [ESP8266_AT_WebServer](https://github.com/khoih-prog/ESP8266_AT_WebServer) page. 2. Download the latest release `ESP8266_AT_WebServer-master.zip`. 3. Extract the zip file to `ESP8266_AT_WebServer-master` directory 4. Copy whole - `ESP8266_AT_WebServer-master` folder to Arduino libraries' directory such as `~/Arduino/libraries/`. ### VS Code & PlatformIO: 1. Install [VS Code](https://code.visualstudio.com/) 2. Install [PlatformIO](https://platformio.org/platformio-ide) 3. Install [**ESP8266_AT_WebServer** library](https://registry.platformio.org/libraries/khoih-prog/ESP8266_AT_WebServer) by using [Library Manager](https://registry.platformio.org/libraries/khoih-prog/ESP8266_AT_WebServer/installation). Search for **ESP8266_AT_WebServer** in [Platform.io Author's Libraries](https://platformio.org/lib/search?query=author:%22Khoi%20Hoang%22) 4. Use included [platformio.ini](https://github.com/khoih-prog/ESP8266_AT_WebServer/blob/master/platformio/platformio.ini) file from examples to ensure that all dependent libraries will installed automatically. Please visit documentation for the other options and examples at [Project Configuration File](https://docs.platformio.org/page/projectconf.html) --- --- Source: https://maker.wiznet.io/mayuri/projects/esp8266-at-webserver/
