Communicate with ESP8266 from host MCU using AT parser library

ESP8266 AT commands parser for RTOS systems

ESP-AT Library commands parser is a generic, platform independent, library for communicating with ESP8266 Wi-Fi module using AT commands. Module is written in C99 and is independent from used platform. Its main targets are embedded system devices like ARM Cortex-M, AVR, PIC and others, but can easily work under Windows, Linux or MAC environments.

ESP_AT_Lib is a library for host device (MCU for example) which drivers ESP32 or ESP8266 devices which run official AT commands firmware written and maintained by Espressif System. Source of official firmware is publicly available in esp32-at repository [Although name might be confusing, it supports ESP32 and ESP8266 aswell]. Official ESP AT firmware is based on Espressif RTOS-SDK.

If you are only interested in using module and not writing firmware for it, you may download pre-build AT firmware from Espressif systems download section and focus only on firmware development on host side, for which you need the library posted here.

Follow documentation for more information on implementation and other details.
