I can't find the answer to this question. I apologize if I this is a dup.
I need to uniquely identify a device, as is often the case.
STM32 has a "Device Electronic Signature" feature. Is there a way to read that value?
I know I could store a value on the SD card or EEPROM. But it is important that the value would be protected from being changed (or copied) by a user.
I could you MAC address (as was suggested somewhere else), but I have seen a thread here on netduino.com about MAC changing. Which is unacceptable.
