Is there a way to get the core’s ID in the firmware itself? Something like a Spark.deviceID variable? I’m creating multiple, similar devices that need to identify themselves (over TCP or UDP) to a RaspPi server.

Get the current core ID on the core itself?

This was implemented in the core some time ago; see this thread:

It returns an Arduino String class object, so myString.toCharArray will get you a C string.

Returning the ID in a variable is a little odd since you need to know that device ID in order to get variables.
