The document introduces AltBeacon, a specification for Bluetooth low energy proximity beacons that allows devices to identify and interact with these beacons. It highlights the advantages of using AltBeacon, including its open-source nature and interoperability, and provides technical details about its implementation and programming interactions through examples and code snippets. Additionally, it includes links to resources for developers and a demo for further exploration.

3. 1.
What is
AltBeacon?
Let’s understand

4. AltBeacon in two points
■ Specification of format of advertisement
messages that Bluetooth Low Energy
proximity beacons broadcast
■ The contents of the emitted messages
contain information that the receiving
device can use to identify the beacon

5. 2.
Why using it?
What are the
advantages?

6. It is open!
You can also provide feedback, opening an
issue on Github

7. Easiness
■Concise proximity
advertisement
message between
advertisers and
scanners
Interoperability
■Avoid
implementation
restrictrions, so easier
format to adopt
Main goals

8. 3.
Implementation
Some technical
details

9. ■The specification
follows the standard
defined in Bluetooth
Specification Version
4.0
■Designed for devices
Bluetooth Low Energy
compliant
Requisites

10. Format

11. 4.
Programming
Interaction with
beacons

12. Interacting with Beacons
Locate Beacon: Android application that
detects beacons and also transmits as a
beacon (on some devices):

■Widely used
■Support for stickers
■Indoor Location SDK
■Cloud support
Comparison with Estimote SDK

15. Demo time!

16. Code snippets
public class RangingActivity extends AppCompatActivity
implements BeaconConsumer {
...
@Override protected void onCreate(Bundle savedInstanceState)
{
...
beaconManager = BeaconManager
.getInstanceForApplication(this);
//estimote layout
beaconManager.getBeaconParsers(). add(new
BeaconParser(). setBeaconLayout("m:2-3=0215,i:4-19,i:20-
21,i:22-23,p:24-24"));
beaconManager.bind(this);
beaconManager.setForegroundScanPeriod(5000l);
...
}

17. Code snippets (2)
public class RangingActivity extends AppCompatActivity
implements BeaconConsumer {
...
@Override protected void onCreate(Bundle savedInstanceState)
{
...
BluetoothAdapter mBluetoothAdapter =
BluetoothAdapter.getDefaultAdapter();
if (!mBluetoothAdapter.isEnabled()) {
Intent enableBtIntent = new
Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent,
REQUEST_ENABLE_BT);
}
...
}

18. Code snippets (3)
public class RangingActivity extends AppCompatActivity
implements BeaconConsumer {
...
@Override
public void onBeaconServiceConnect() {
beaconManager.setRangeNotifier(new
BeaconRangeNotifier());
try {
beaconManager.startRangingBeaconsInRegion(new
Region("RangingUniqueId", null, null, null));
} catch (RemoteException e) { }
}
