More than 371 million Bluetooth enabled beacons are projected to ship by 2020 research by ABI Research

iBeacon • iBeacon protocol supports both iOS and Android • Beacon manufacturer need to be vetted by Apple to be iBeacon compliance • iBeacon transmits simple data fields like UUID, Major ID, and Minor ID.

Eddystone • Eddystone supported beacons can emit three different frame type signals • All three frame types are supported by both Android and iOS • Open standard / open source (github.com/google/eddystone)

Eddystone-UID • Similar to iBeacon, the beacon which supports Eddystone UID needs an app to receive designated UID for the app to recognize • Eddystone’s UID have 16 digit strings to identify a beacon uniquely, 10 character Namespace to identify an entity / organization and a 6 character Instance to identify individual beacons • Eddystone-EID

Eddystone-URL • Eddystone URL supported beacons does not require an app to catch the data transmitted from it but it requires a beacon supported browser installed. • Eddystone URL broadcasts a URL, which can link to any site. • This is basically for the “Physical Web”, where developer can put content which everyone can access it. (http://google.github.io/physical- web/)

Eddystone-TLM • These beacons send Eddystone UID, Eddystone URL and beacons health status like battery life, diagnostic data etc. • These are mainly intended for beacons fleet management and they transmits data less frequently compared to other two.

Beacons and Android before 2016

Scanning for beacons BluetoothAdapter BluetoothAdapter.LeScanCallback mLeScanCallback = new BluetoothAdapter.LeScanCallback(){ @Override public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord){ } }; device - Identifies the remote device rssi - The RSSI value for the remote device as reported by the Bluetooth hardware. scanRecord - The content of the advertisement record offered by the remote device.

Nearby API • We don’t have to deal with bluetooth runtime permissions • But we need to ask user to allow Nearby

Nearby notifications

Takeaways #1 • Only https:// addresses are supported • Scan is performed only when screen is turning on • App intents are currently available only for Google Partners

Takeaways #1 • Only https:// addresses are supported • Scan is performed only when screen is turning on • App intents are currently available only for Google Partners • App intent are available for anyone!

Physical Web

Physical Web • Open standard that everyone can use • No proactive notifications • Open Source • BLE energy efficient & widespread • Built on web and urls • Can use mDNS too • Context is the king • Connect digital and real world • Use Eddystone URL beacons • Supported by Chrome for Android, Opera for Android

Physical Web

Takeaways #2 • With great power comes great resposibility • Nearby API is easy and energy efficient • Nearby Notifications are the most easy way to start using Beacons on Android
