ESP32-C5 compatibility with AT commands

Postby NavitTripathi » Thu Jul 17, 2025 7:02 am

Hi, I recently purchased the ESP32-C5 and would like to know which version of ESP-IDF is compatible with it.
My goal is to use the ESP32-C5 in dual-band mode (2.4GHz and 5GHz) with support for both Station and Access Point modes.
Could you please assist me with this? Is there an AT command firmware available that I can directly install on the C5 to enable AT command support? If not, which sample code should I use with the C5 to achieve my objectives?

https://github.com/espressif/esp-at
says that the latest ("master") version supports the C5.

I hope you are well.
Following your earlier suggestion, I reviewed the GitHub code and noticed in the README file the statement:
“Supported: Supported versions. You can click the alt text to go to the corresponding branch and develop your own AT firmware.”
From this, I understand that for the supported ESP-IDF versions, we are expected to develop our own AT firmware.
Could you kindly guide me through the process of developing custom AT firmware? Specifically, I would appreciate any recommended steps, tools, or documentation that would assist in building and customizing the AT command set based on our project requirements.

I believe what is meant there is that you have to build the firmware binaries yourself instead of downloading a pre-built binary release.
