Just like any other technology, Bluetooth Low Energy Beacons work with a protocol set. It is like a profile that tells how a beacon is broadcasting information. This information is then handled by a device (typically a cell phone) with the same protocol. Both ends should know the definition of the broadcast data if they want a successful transmission. This is why the broadcast data type is defined by the type of protocol the beacon is using. In some cases, it broadcasts a UUID-based URI, while in other cases, it broadcast URLs or telemetry packets.

The broadcast data type is defined by the type of protocol the beacon is using. In some cases, it broadcasts a UUID-based URI, while in other cases, it broadcast URLs or telemetry packets. In this section, we will discuss two widely used beacon protocols: Eddystone by Google and iBeacon...
