determine (universally) unique identifier #1

Closed Bdenouden closed 4 years ago

Bdenouden commented 4 years ago

ESP getChipId() is semi unique. Its based on a series number set by the manufacturer. although the chance of collision is VERY low, it is not none.

This is likely enough for prototyping purposes but must be reviewed before this can be turned into an actual product.

Could use MAC address? Should be unique

Bdenouden commented 4 years ago

MAC address is based on the same series number so has the same issue... I guess it'll be fine, we can always insert a check based on the interval between communications: a resend within the expected 'quite' period could indicate flaws. for now ill mark this as closed!
