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

  • alt text: Released versions, you can click alt text to go to the corresponding release page and download the AT firmware.
  • alt text: Supported versions, you can click alt text to go to the corresponding branch and develop your own AT firmware.
  • alt text: Pre-release versions, expected to release AT firmware for the corresponding chip soon.

Please choose one of the following options based on your needs:

  • The default AT firmware meets your requirements: It is recommended to use the latest released version of the firmware corresponding to the chip.
  • The default AT firmware does not meet your requirements and stability is a priority: It is recommended to develop your AT firmware based on the latest released version of the firmware corresponding to the chip.
  • The default AT firmware does not meet your requirements and you want more new features: It is recommended to develop your AT firmware based on the master branch.

Other series of chips:

  • ESP-AT will support ESP32-C5 series of chips.
  • ESP-AT will not support ESP32-S3 and ESP32-H series of chips.
