I have two text books that cover Bluetooth and have read multiple articles and not one has mentioned the need to do that.
What I read in the documentation is that the UUID is random: "A Universally Unique Identifier (UUID) is a standardized 128-bit format for a string ID used to uniquely identify information. The point of a UUID is that it's big enough that you can select any random and it won't clash. In this case, it's used to uniquely identify your application's Bluetooth service. To get a UUID to use with your application, you can use one of the many random UUID generators on the web, then initialize a UUID with fromString(String)." Are you saying that there is some sort of table that exists that specifies my exact device?
