ESP-AT

• 中文版

esp-at project was started and powered by Espressif Systems (@espressif) as an official project, for the ESP32-C2, ESP32-C3, ESP32-C6, ESP32, and ESP32-S2 Series SoCs provided for Windows, Linux, and macOS.
It is now supported and maintained by Espressif esp-at team (@esp-at).

Introduction

Espressif SoC chipsets are often used as add-on modules to seamlessly integrate wireless connectivity features into new and existing products. In an effort to facilitate this and cut down on engineering costs, Espressif Systems has developed a set of AT commands (Please select your target chip from the dropdown menu in the top left corner of the page) that can be used to interface with Espressif products.

The AT solution provided by Espressif allows for rapid integration by providing:

• In-built a large number of AT commands
• Easy integration with resource-constrained host platforms
• Easy-to-parse command-response protocols
• Customized, user-defined AT commands
