In order to complete the tutorials in this book, you don't need to be in possession of any iBeacon hardware since there's a companion app that lets your Mac act as an iBeacon using its built-in Bluetooth adapter provided it has Bluetooth 4.0.
If your machine doesn't have Bluetooth 4.0, there's no need to worry. You can pick up a Bluetooth 4.0 USB dongle for under $ 15 that will allow the companion app to work.
Click on the Apple icon in the status bar.
Select About This Mac.
Click on the More Info button.
Click on the System Report button.
Select Bluetooth from the sidebar on the left, underneath Hardware.
Scan down the list of information until you find LMP Version, as shown:
If your Mac is equipped with Bluetooth 4.0, LMP Version will say 0x6. Anything lower than that is an older version of Bluetooth and will need a USB dongle.
The Mac in the preceding screenshot needs a dongle.
The earlier screenshot shows a MacBook Pro fitted with Bluetooth 3.1 and will need a USB dongle.
While writing this book, I used a MacBook Pro from late 2011, which unfortunately is only fitted with Bluetooth 3.1. I picked up a pluggable USB-BT4LE Bluetooth 4.0 USB Adapter for $ 13, which enabled my MacBook for iBeacon transmissions.
The companion app is used throughout the book and lets you use your Mac as an iBeacon. It can be downloaded from the download section of the Packt Publishing website and comes preconfigured with all of the beacons used throughout the book.
Using the companion app, you can simulate physical beacons in the real world using any Bluetooth-4.0-powered Mac running OS X Mavericks or Mountain Lion.
The companion OS X app has beacons configured already for every tutorial in this book. To start a beacon, simply select the beacon from the tutorial from the menu on the left, and then tap on the power button in the right panel.
