How to read MAC address from efuse?

Barry asked 5 months ago

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

Thanks
Barry

Hi.
I think you can use something like this: ESP.getEfuseMac()
Take a look at this: https://forum.arduino.cc/t/convert-mac-address-to-string/644713/5
Let me know if this is what you’re looking for.
Regards,
Sara
