Core ID generation scheme

Is there a defined scheme for core IDs? Based on the ~10 cores my group has registered, it looks like they all start with 5[345]ff, end with 67, and are 24 hex characters long. Is this coincidental?

See here: https://github.com/spark/firmware/blob/master/src/spark_utilities.cpp#L520

Basically the 96bit hardware ID on the STM32 :slight_smile:

Great, thanks for the pointer!
