This document compares the differences among AT firmwares of a certain {IDF_TARGET_NAME} series in terms of the supported commands set, hardware, and supported modules.
This section describes the differences among AT firmwares of {IDF_TARGET_NAME} series, including
.. only:: esp32 - ESP32-WROOM-32-AT-Vx.x.x.x.zip (referred to as **WROOM Bin** in this section); - ESP32-WROVER-32-AT-Vx.x.x.x.zip (referred to as **WROVER Bin** in this section); - ESP32-PICO-D4-AT-Vx.x.x.x.zip (referred to as **PICO-D4 Bin** in this section); - ESP32-SOLO-1-AT-Vx.x.x.x.zip (referred to as **SOLO-1 Bin** in this section); - ESP32-MINI-1-AT-Vx.x.x.x.zip (referred to as **MINI-1 Bin** in this section); - ESP32-D2WD-AT-Vx.x.x.x.zip (referred to as **D2WD Bin** in this section);
.. only:: esp32c2 - ESP32C2-2MB-AT-Vx.x.x.x.zip (referred to as **ESP32C2-2MB Bin** in this section); - ESP32C2-4MB-AT-Vx.x.x.x.zip (referred to as **ESP32C2-4MB Bin** in this section); - ESP32C2-BLE-2MB Bin (firmware is not released, but you can download the ``esp32c2-ble-2mb-at`` firmware from :doc:`GitHub Actions <How_to_download_the_latest_temporary_version_of_AT_from_github>`, or `Compile ESP-AT Project Locally <How_to_clone_project_and_compile_it>` by yourself);
.. only:: esp32c3 - ESP32-C3-MINI-1-AT-Vx.x.x.x.zip (referred to as **MINI-1 Bin** in this section);
.. only:: esp32c6 - ESP32C6-4MB-AT-Vx.x.x.x.zip (referred to as **ESP32C6-4MB Bin** in this section);
The table lists which command set is supported by default in the official AT firmware applicable to {IDF_TARGET_NAME} series of modules (marked with |icon-green-check|), which is not supported by default but can be supported after configuration of the ESP-AT project (marked with |icon-orange-check|), and which is not supported at all (marked with |icon-red-cross|). Note that the command set that is not shown in this table is not supported either. Applicable firmware that has not been :doc:`officially released <../AT_Binary_Lists/index>` requires compilation by yourself. Those self-compiled firmware cannot be upgraded OTA from Espressif official server.

The table below lists the modules or chips that are default supported by the officially released {IDF_TARGET_NAME} series AT firmware (indicated by |icon-green-check|), the modules that are not supported by default but can be modified to be supported using the :doc:`../Compile_and_Develop/tools_at_py` (indicated by |icon-orange-check|), and the modules that are not supported at all (indicated by |icon-red-cross|). For modules that are not supported at all, you can refer to :doc:`../Compile_and_Develop/How_to_clone_project_and_compile_it` to modify the configuration as needed for support.
