We are now ready to have the Central Mode ask a question to one of its Magic 8-Balls.
After we are done with this step, we will be able to run an instance of the app as a Central (on a Mac, iPhone/iPad/iPod, Watch or TV), and an instance of the app as a Peripheral (on a Mac or iPhone/iPad/iPod).
The Central will discover the Peripheral, and display its name in the list. The user will then be able to select the Peripheral, and “ask it a question.”
The Peripheral device will almost immediately display the question.
