This is documentation of ESP-AT, a solution developed by Espressif to quickly and easily interface with ESP32 products.
Espressif Wi-Fi and Bluetooth 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 AT firmware as well as a rich set of AT commands that can be used to interface with Espressif products.
The AT firmware allows for rapid integration by providing:
In-built TCP/IP stack and data buffering
Easy integration with resource-constrained host platforms
Easy-to-parse command-response protocols
Customized, user-defined AT commands
