Released Firmware

[中文]

It is recommended to use the lastest version of firmware. Currently, Espressif releases AT firmware for the following ESP32-C2 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
