2. What is a beacon ?
3. WHAT IS A BEACON ? BLUETOOTH LOW ENERGY BROADCAST +
4. BLUETOOTH LOW ENERGY IDENTIFICATION TELEMETRY
5. BLUETOOTH LOW ENERGY POWER 1 year on a AA battery (basic usage with ID) DISTANCE 30 to 50m (configurable, up to 150m) AVAILABLE on many mobile devices
6. IBEACON
7. IBEACON UUID+MAJOR+MINOR Micro location TX POWER FAR, NEAR, IMMEDIATE zones
8. IBEACON #CORELOCATION APPLICATION WAKE UP
9. IBEACON PROBLEMS BATTERIES ALWAYS DIE DATA MUST BE RETRIEVED FROM A SERVER PROPRIETARY
10. IBEACON + ANDROID ? LEGAL ISSUES BLE SCAN

24. associate blob of data monitor the health of your beacons works with Eddystone + iBeacon PROXIMITY BEACON API
25. PROXIMITY BEACON API 16 bytes UID status (active/inactive) stability (stable/moving) latitude longitude REGISTER Indoor floor level Google Places ID Description Arbitrary properties
26. PROXIMITY BEACON API MONITOR Predicted battery death Beacons moved away from their location Unusually low detection rates
27. auto detect beacons nearby retrieve associated blob of data NEARBY MESSAGES API
28. MessageListener messageListener = new MessageListener() {
 @Override
 public void onFound(Message message) {
 String nearbyMessageNamespace = message.getNamespace();
 String nearbyMessageType = message.getType();
 String nearbyMessageString = new String(message.getContent());
 
 Log.i(TAG, "Message string: " + nearbyMessageString);
 Log.i(TAG, "Message namespaced type: " + nearbyMessageNamespace +
 "/" + nearbyMessageType);
 }
 };
 
 // Use Strategy.BLE_ONLY because we are only interested in messages that we
 // attached to BLE beacons.
 Nearby.Messages.subscribe(client, messageListener, Strategy.BLE_ONLY)
 .setResultCallback(new ErrorCheckingCallback("subscribe()")); NEARBY MESSAGES API
