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-C5, ESP32-C6, ESP32-C61, 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). Before using the ESP-AT solution, please read the disclaimer carefully and comply with its terms and precautions.

Introduction

Espressif SoCs serve as add-on modules, easily integrating wireless connectivity into existing products. To reduce development costs, Espressif offers a set of AT commands (select your target chip from the dropdown menu in the top left corner) that enable users 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
