2. Bluetooth LE
• Aka
Bluetooth Smart
• Released
in June 2010
• Completely
• Designed
new specification (by Bluetooth SIG)
to enable very low power devices to run for years
• Asynchronous
• NOT
connection oriented
2

3. What is Bluetooth LE good for?
• Connecting
sensors)
• Accessing
• Low
things we carry with us (watches, tags, body
the things around us
duty cycle M2M communication
• Communication
• Connecting
within a system (wheels to car)
anything that has intrinsic data to the Internet
3

4. Prediction
• Bluetooth
LE will be to smartphones what USB
has been to desktop PCs: universal peripheral
connectivity
4

5. Our case
• Connect
a BLE device to an iPhone
5

6. iBeacons
• Region
monitor
• Micro
locations
• Range
awareness
• Indoor
• Awake
• In
your app by push notifications using iBeacons
app notifications when user enters / leaves a region
6

7. What can be an iBeacon?
• Third
party BLE devices or iOS devices
7

8. All iOS devices?
• NO
• Only
these devices:
• iPhone 5
• iPhone 4S
• iPad mini
• iPad with Retina display (4th gen)
• iPad (3rd gen)
• iPod touch (5th gen)
• with iOS Version 5.1.1 or above.
8

9. Other devices
• Android
devices with Bluetooth 4.0 and Android 4.3 and
later (Samsung Galaxy S3/S4, Samsung Galaxy Note II, HTC
One, Nexus 7 2013 edition, Nexus 4, HTC Butterfly, Droid
DNA)
• MacIntosh
computers equipped with OS X 10.9 (Mavericks)
and Bluetooth 4.0 using the MacBeacon application from
Radius Networks.

10. CLBeaconRegion
• Defines
a type of region that is based on the device’s
proximity to a Bluetooth beacon (or many)
• One “Region” does not mean physically close, could be all
over the world
• proximityUUID: identifier that you use to identify your
company’s beacons
• mayor: number could represent a group of beacons in the
region
• minor: is the unique identifier for the beacon

11. Emitter
NSUUID *uuid = [[NSUUID alloc]
initWithUUIDString:@23542266-18D1-4FE4-B4A1-23F8195B9D39];
!
self.beaconRegion = [[CLBeaconRegion alloc]
initWithProximityUUID:uuid
major:1
minor:4
identifier:@com.devfright.myRegion];
11

12. Receiver
- (void)initRegion {
NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:@B9407F30-F5F8-466EAFF9-25556B57FE6D];
self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uuid
identifier:@com.devfright.myRegion];
[self.locationManager startMonitoringForRegion:self.beaconRegion];
}
12

13. CLBeacon
• Identifying
the Beacon
• proximityUUID
• major
• minor
• Determining the Beacon Distance
• proximity unknown, immediate, near, far
• accuracy (meters)
• rssi (dbm)
13

14. CLLocationManager delegate
-(void)locationManager:(CLLocationManager *)manager
didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion
*)region {
CLBeacon *beacon = [[CLBeacon alloc] init];
beacon = [beacons lastObject];
self.beaconFoundLabel.text = @Yes;
if (beacon.proximity == CLProximityUnknown) {
NSLog(@Unknown Proximity);
} else if (beacon.proximity == CLProximityImmediate) {
NSLog(@Immediate);
} else if (beacon.proximity == CLProximityNear) {
NSLog(@Near);
} else if (beacon.proximity == CLProximityFar) {
NSLog(@Far);
}
}

15. Third party vendors
• Kontakt.io: they
sell 10 beacons for $279; 5 beacons for
$149 and 3 beacons for $99
• Estimote: 3
• BLE
beacons for $99
mini (RedBearLab): 1 for $35 (development kit)
• Texas
instruments: CC2541 Mini Development Kit
