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 protocol gives a definition to the data broadcast.
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 by Apple.
