ESP-AT 固件差异

:link_to_translation:`en:[English]`

本文档比较了同一 ESP 系列的 AT 固件在支持的命令集、硬件、模组方面的差异。

ESP32 系列

本节介绍以下 ESP32 系列 AT 固件的区别：

  • ESP32-WROOM-32_AT_Bin（本节简称为 WROOM Bin）
  • ESP32-WROVER-32_AT_Bin（本节简称为 WROVER Bin）
  • ESP32-PICO-D4_AT_Bin（本节简称为 PICO-D4 Bin）
  • ESP32-SOLO-1_AT_Bin（本节简称为 SOLO-1 Bin
  • ESP32-MINI-1_AT_Bin（本节简称为 MINI-1 Bin）
  • ESP32-D2WD_AT_Bin（本节简称为 D2WD Bin）
  • ESP32-QLOUD_AT_Bin（本节简称为 QCLOUD Bin）

支持的命令集

下表列出了官方适配的 ESP32 系列 AT 固件默认支持哪些命令集（用 |icon-green-check| 表示）、默认不支持但可以在配置和编译 ESP-AT 工程后支持的命令集（用 |icon-orange-check| 表示）、完全不支持的命令集（用 |icon-red-cross| 表示），下表没有列出的命令集也为完全不支持的命令集。正式发布的固件见 :doc:`../AT_Binary_Lists/index`，已适配但未发布的模组固件，需要自行编译。自行编译的固件无法从乐鑫官方服务器进行 OTA 升级。
