v5.0.0.0 is released for ESP32-C5 and ESP32-C61. It is the first released version of AT firmware for ESP32-C5 and ESP32-C61.

ESP32C5-AT

Documentation for Release v5.0.0.0 is available at https://docs.espressif.com/projects/esp-at/en/release-v5.0.0.0/esp32c5/index.html.

Please contact Espressif Sales or [email protected] for AT firmware suitable for the ESP32-C5 series chips. If you contact us via email, please include "Request ESP32-C5 AT Firmware Download Link" in the subject line, and provide the following information in the email body: your company name, the Espressif product you are using, project name, application scenario, project start date, expected mass production date, project status, annual estimated purchase quantity, and the required AT firmware version.

Known Issues
