Bluetooth 4.0
•
•
•
•
Cos’è?!
Il solito bluetooth? NO!
Chi lo usa?!
Come lo uso nella mia app?

9. Bluetooth 4.0: cos’è?
❖
BLE: Blueooth Low Energy!
❖
Standard dal 2010!

10. Bluetooth 4.0: Le novità
❖
Completamente differente!!
❖
Niente abbinamenti, PIN etc.!
❖
Advertising continuo!
❖
❖

❖
Range: 50m vs 100m!
❖
Throughput: 0.27 Mbit/s vs 2.1 Mbit/s!
❖
Latency: 6ms vs 100ms

12. Bluetooth 4.0: Le novità

http://is.gd/blegatt!
❖
Rivolto a developer!
❖
Rivolto a hardware makers

15. Bluetooth 4.0 in iOS
❖
CoreBluetooth.framework!
❖
Disponibile su iOS e Mac OS!
❖
CBPeripheral (ogni BLE device)!
❖
CBCentralManager (iOS BLE)

16. Bluetooth 4.0 in iOS
❖
init CBCentralManage!
❖
ricercare e connettersi con i BLE device che trasmettono!
❖
esplorare le info del device BLE (CBPeripheral)!
❖
Ricevere e inviare richieste con data!
❖
Registrare notifiche per cambio valori

17. Bluetooth 4.0 in iOS: Discovering
myCentralManager =!
[[CBCentralManager alloc] initWithDelegate:self queue:nil options:nil];
[myCentralManager scanForPeripheralsWithServices:nil options:nil];
- (void)centralManager:(CBCentralManager *)central!
didDiscoverPeripheral:(CBPeripheral *)peripheral!
advertisementData:(NSDictionary *)advertisementData!
RSSI:(NSNumber *)RSSI {!
!
NSLog(@"Discovered %@", peripheral.name);!
!
}

18. Bluetooth 4.0 in iOS: Connecting
[myCentralManager connectPeripheral:peripheral options:nil];
- (void)centralManager:(CBCentralManager *)central!
didConnectPeripheral:(CBPeripheral *)peripheral {!
!
NSLog(@"Peripheral connected");!
...
peripheral.delegate = self;!

19. Bluetooth 4.0 in iOS: Services
- (void)peripheral:(CBPeripheral *)peripheral!
didDiscoverServices:(NSError *)error {!
!
for (CBService *service in peripheral.services) {!
NSLog(@"Discovered service %@", service);!
...!
}!
...

20. Bluetooth 4.0 in iOS: Services
NSLog(@"Discovering characteristics for service %@", interestingService);!
[peripheral discoverCharacteristics:nil forService:interestingService];
- (void)peripheral:(CBPeripheral *)peripheral!
didDiscoverCharacteristicsForService:(CBService *)service!
error:(NSError *)error {!
!
for (CBCharacteristic *characteristic in service.characteristics) {!
NSLog(@"Discovered characteristic %@", characteristic);!
...!
}!
...!

21. Bluetooth 4.0 in iOS: Read
NSLog(@"Reading value for characteristic %@", interestingCharacteristic);!
[peripheral readValueForCharacteristic:interestingCharacteristic];
- (void)peripheral:(CBPeripheral *)peripheral!
didUpdateValueForCharacteristic:(CBCharacteristic *)characteristic!
error:(NSError *)error {!
!
NSData *data = characteristic.value;!
// parse the data as needed!
...

Cos’è?!
Come funziona?!
Come si costruisce?!
Quanto costa?!
Come lo uso nella mia app?

25. iBeacons
iBeacon, a new class of low-powered, low-cost
transmitters that can notify nearby iOS 7 devices of
their presence, provides apps a whole new level of
location awareness, such as trail markers in a park,
exhibits in a museum, or product displays in stores.

26. iBeacons: trasmette..?
❖
3 info: UUDID, major, minor!
❖
SEMPRE!
❖
a qualsiasi BLE device attivo!
❖
nothing else matter

27. iBeacons IDs
❖
UUDID: E2C56DB5-DFFB-48D2-B060-D0F5A71096E0!
❖
Major: int!
❖
Minor: int!
❖
Major e Minor ID qualunque, ID generici

28. iBeacons IDs
❖
UUDID: E2C56DB5-DFFB-48D2-B060-D0F5A71096E0
McDonald!
❖
Major: int 17
Grosseto!
❖
Minor: int 9
Cassa 9!
❖
quindi…!
❖
sei nel McDonald di Grosseto alla Cassa 9.
propongo pagamento tramite app per il conto della Cassa 9.

29. iBeacons IDs
❖
UUDID: E2C56DB5-DFFB-48D2-B060-D0F5A71096E0
Museo Uffizi!
❖
Major: int 2
Piano 2!
❖
Minor: int 13
Quadro 13!
❖
quindi…!
❖
sei nel Museo al secondo piano davanti al quadro 13.
propongo audio guida per quel quadro.

30. iBeacons: come funziona?
❖
