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 if you need to modify the following configurations, you can generate a new firmware for your module by modifying the released firmware using the at.py Tool.

• Modify UART Configuration

• Modify Wi-Fi Configuration

• Modify Certificate and Key Configuration

• Modify GATTS Configuration

Before using the AT firmware below, please read the Disclaimer carefully and comply with its terms and precautions.
