Lightweight ESP-AT parser

LwESP is lightweight ESP AT commands parser library to communicate with ESP8266 or ESP32 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 as an example) which drives ESP32 or ESP8266 devices running official AT commands firmware written and maintained by Espressif System. Source of official firmware is publicly available at esp32-at repository.

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 details.
