    Why not program a UUID in EEPROM once? There is no hardware UUID. https://stackoverflow.com/questions/21559264/unique-machine-id-for-arduino-project – Maximilian Gerhardt Apr 13 '18 at 09:29

You don't have a UUID.

You only get a UUID in the USB-enabled chips, like the ATMega32U4.

You would have to create your own UUID and store it in EEPROM, or embed it within your sketch.
