This is documentation of ESP-AT, a solution developed by Espressif to quickly and easily interface with {IDF_TARGET_NAME} 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 :doc:`AT firmware <AT_Binary_Lists/index>` as well as a rich set of :doc:`AT commands <AT_Command_Set/index>` that can be used to interface with Espressif products.
ESP-AT Solution
The AT firmware allows for rapid integration by providing:
- In-built TCP/IP stack and data buffering
