Released Firmware

[中文]

It is recommended to use the lastest version of firmware. Currently, Espressif only releases AT firmware for the following ESP32 series of modules.

Note

If there is no released firmware for your module, you can either use the firmware for the module that has the same hardware configuration as yours (see ESP-AT Firmware Differences for which module has the same configuration), or create a factory parameter bin for your module (see How to Generate Factory Parameter Bin for details).
