Are Android Wear Node IDs Unique

Question

Are Android Wear Node ids unique (is it safe to store a node's id as a reference to a specific wear device)?

If not, is there a unique way to identify a specific wear device?

Answer 1

Android Wear node ids are based on UUIDs, which should be unique, according to the documentation here: http://developer.android.com/reference/java/util/UUID.html
