I’d like to read the MAC address. Ive found where it is stored in efuse.  Using the Arduino IDE (C language), how do I read the efuse?  Is there a special command for efuse access or other?

There is this thread where Robert Ralston has read the efuse using python?

I’m looking into this as well:  https://esp32.com/viewtopic.php?t=11556&start=10#p46866
