LwESP is lightweight ESP AT commands parser library to communicate with ESP8266 or ESP32 Wi-Fi modules using AT commands. Module is written in C99 and is system platform agnostic. 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 too.

Espressif module runs official AT Commands (esp-at) software and communicates with host device via UART or SPI communication protocol.

Follow documentation for more information on implementation and details.

• Supports latest ESP32, ESP32-C2, ESP32-C3, ESP32-C6 & ESP8266 AT software from Espressif system
• Platform independent and very easy to port
• Development of library under Win32 platform
• Available examples for ARM Cortex-M, Win32 or POSIX (mostly Linux) platforms
• Written in C language (C99)
• Allows different configurations to optimize user requirements
• Supports implementation with operating systems with advanced inter-thread communications
• Uses 2 tasks for data handling from user and device
• Includes several applications built on top of library
