Released Firmware

[中文]

It is recommended to use the lastest version of firmware. Currently, Espressif releases AT firmware for the following ESP32-C3 series of modules.

Note

• The AT firmware versions v2.2.0.0 to v3.2.0.0 support the ESP32-C3 ECO0 (Rev v0.0) to ECO4 (Rev v0.4) series chips (including ECO0 and ECO4).

• The AT firmware version v3.3.0.0 supports the ESP32-C3 ECO0 (Rev v0.0) to ECO4 (Rev v0.4), ECO6 (Rev v1.0), and ECO7 (Rev v1.1) series chips.

• 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
