ESP01 last firmware version for MQTT AT commands

Postby RobertoArg » Sun Oct 08, 2023 11:44 pm

Hello all !
For a project that uses a microcontroller connected to a ESP01 module I need to confirm which is the best firmware version to FLASH the module in order to use MQTT via AT commands. If you please include a download link.
I bought a couple of modules that came with a weird firmware version not recognizing AT commands.
Thank you in advance.

You probably want to look at the repository where ESP-AT is maintained. Also, you seem to accidentally have had caps lock on while typing the title, I've taken the liberty to fix that.

Thank you very much for correcting the title. I am sorry for that.
As I am new to ESP8266 ESP32 and mostly with ESP01, my questions are very basic.
I would need extra guidance, such as specific version number and a link, because there are so many variants that I get confused.
Starting by: if ESP01 is exactly an ESP32 in terms of firmware, specifically for my purpose of MQTT via AT commands, or there is a particular version that fits ESP01?

I can also see that many titles concerning AT are in Chinese so what I am looking for it is hard to find.
The link I am checking is: https://github.com/espressif/esp-at and there ESP32-C2、ESP32-C3、ESP32-C6、ESP32、and ESP8266 are mentioned. ESP01 is not mentioned, except that as I asked before, ESP01 would be exactly the same.

Thank you again for your kind reply.

I'll move your question to the ESP-AT forum; they'll be able to help you better there.

The ESP01 module is not an espressif product; it is a module developed based on the ESP8266 chip. Espressif has not directly developed AT firmware for the ESP01.

If you are looking for AT firmware, we recommend considering chips such as ESP32-C3, ESP32-C2, or ESP32-C6 as a priority.

If you are having difficulty selecting a chip, please visit: https://products.espressif.com/#/product-selector. If you still can't resolve your issue, please contact us at https://www.espressif.com/en/contact-us/sales-questions.

For documentation related to AT firmware, please refer to: https://docs.espressif.com/projects/esp ... index.html.
