ESP32 AP name?

[kbaud1]

Does the ESP32 come already set with a unique MAC address (or something like this) for wifi? Where is it programmed? (in Efuse, flash, etc.) For example can multiple ESP32's power up in the same room and be connected to as AP's at the same time from different computers, without them thinking they are the same thing?

I am hoping to give the controller a default factory Wi-Fi name that the user can change (similar to how people set the name of a router they buy. To do this I would store the custom wifi name in flash somewhere so it is still set when the power is reset. This would make it easy for customers with multiple machines to manage the identities of them and keep it from being confusing.

Do you see any issues with this plan?

Yes, it does come with an unique MAC; it's factory-programmed in eFuses. And I see no reason your plan won't work.

I think it would be more professional to use "WiFiManager" to give your client the option to provide an SSID, password, and other configuration information to you ESP32
