Communication model of BLE Beacons

Bluetooth Low Energy Beacons are based on the one-way communication model. This is important because it will be inappropriate if someone changes the broadcast data on the beacons. Bluetooth Low Energy Beacons are supported by two of the best companies in the consumer electronics market. Google and Apple have their own protocols made for Bluetooth beacons. Google Eddystone is an Apache 2.0-licensed cross platform profile available for Bluetooth beacons. It works on different frame types like Eddystone-UID, Eddystone-URL, and Eddystrong-TLM. iBeacons, on the other hand, is a protocol developed by Apple in 2013 serving the same purpose. These topics are discussed in a greater detail in Chapter 4, Bluetooth Low Energy Beacons.
