Device ID stored in core?

Firmware
9

This is already in the core firmware in

You call it like this:

String myIDStr = Spark.deviceID();
...
Serial1.print(myIDStr);

I had trouble and had to factory reset when I called deviceID() in loop but calling it to initialize a global worked fine.

[EDIT: don’t redefine the symbol “id” if you want your core to work. I think a bunch of the :spark: code needs underscores added to private vars.]
