Where did you buy your esp32 module/board and was there a firmware preloaded?

AliExpress and yes, firmware preloaded.

Which seller and part number? It is possible that ai-thinker or some other 3rd party manufacturer is shipping their own AT command firmware but I don't think it is provided by ...

Hi @wziy520,

As I mentioned in my previous post, I tried with a few basic AT commands such as AT+CWJAP which do work. Thanks.

There is an AT firmware in development for ESP32, but I don't think a reference of this kind is available yet. It will be similar to the ESP8266 AT command set.

I guess ESP32 resources are way too high to make it a slave system based on standard AT commands. It would be similar to wasting a 600 DMIPS dual core SoC on a system with just one function available.
So probably a custom command set can be defined for specific applications with ESP32 as slave ...

Hi,

I think for the most part, we can use the same AT commands as with ESP8266. I have tried with a few basic AT commands such as AT+CWJAP which do work. Nevertheless, I did not test all.

Please do share if there is extra AT commands for ESP32, since it does have BLE.
