iBeacons e le novità di BLE

Bluetooth 4.0

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

Bluetooth 4.0: cos’è?

❖ BLE: Blueooth Low Energy!

❖ Standard dal 2010!

❖ Chip diverso dal 3.0-!

❖ Dual Chip Device

Bluetooth 4.0: Le novità

❖ Completamente differente!!

❖ Niente abbinamenti, PIN etc.!

❖ Advertising continuo!

❖ Low Power! 0.01-0.5 (BLE) vs 1 (classic)!

❖ Peak di <15 mA vs <30mA di classic

Bluetooth 4.0: Le novità

❖ Range: 50m vs 100m!

❖ Throughput: 0.27 Mbit/s vs 2.1 Mbit/s!

❖ Latency: 6ms vs 100ms

Bluetooth 4.0: Le novità

❖ Niente auricolari Bluetooth 4.0!

❖ Niente scambio foto à la Symbian!

❖ Niente cuffie BLE!

❖ quindi? che ci faccio?

Bluetooth 4.0: Chi lo usa?❖ Orologi!

❖ Sport e fitness devices!

❖ Healtcare devices!

❖ Security devices!

❖ Proxymity!

❖ Automation!

❖ …

Bluetooth 4.0: Profili disponibili

❖ GATT Profiles:!

❖ http://is.gd/blegatt!

❖ Rivolto a developer!

❖ Rivolto a hardware makers

Bluetooth 4.0 in iOS

❖ CoreBluetooth.framework!

❖ Disponibile su iOS e Mac OS!

❖ CBPeripheral (ogni BLE device)!

❖ CBCentralManager (iOS BLE)

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

Bluetooth 4.0 in iOS: DiscoveringmyCentralManager =! [[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);!!}

Bluetooth 4.0 in iOS: Connecting[myCentralManager connectPeripheral:peripheral options:nil];

- (void)centralManager:(CBCentralManager *)central! didConnectPeripheral:(CBPeripheral *)peripheral {! ! NSLog(@"Peripheral connected");! ...

peripheral.delegate = self;!

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

Bluetooth 4.0 in iOS: Services NSLog(@"Discovering characteristics for service %@", interestingService);!

- (void)peripheral:(CBPeripheral *)peripheral!didDiscoverCharacteristicsForService:(CBService *)service! error:(NSError *)error {! ! for (CBCharacteristic *characteristic in service.characteristics) {! NSLog(@"Discovered characteristic %@", characteristic);! ...! }! ...!

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! ...

[peripheral setNotifyValue:YES forCharacteristic:interestingCharacteristic];

iBeacons e le novità di BLE

iBeacons

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

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.

iBeacons: trasmette..?

❖ 3 info: UUDID, major, minor!

❖ SEMPRE!

❖ a qualsiasi BLE device attivo!

❖ nothing else matter

iBeacons IDs

❖ UUDID: E2C56DB5-DFFB-48D2-B060-D0F5A71096E0!

❖ Major: int!

❖ Minor: int!

❖ Major e Minor ID qualunque, ID generici

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.

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.

iBeacons: come funziona?

❖ iOS device!

❖ MiniPC con Bluetooth 4.0!

❖ Standalone device!

❖ Estimone, etc..

iBeacons: iOS Beacon AdvProgetto AirLocate!

CoreBluetooth.framework

_peripheralManager = [[CBPeripheralManager alloc] initWithDelegate:self queue:dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)];

NSDictionary *peripheralData = nil; if(_uuid && _major && _minor) { CLBeaconRegion *region = [[CLBeaconRegion alloc] initWithProximityUUID:_uuid major:[_major shortValue] minor:[_minor shortValue] identifier:@"com.apple.AirLocate"]; peripheralData = [region peripheralDataWithMeasuredPower:_power]; }

[_peripheralManager startAdvertising:peripheralData];

iBeacons: Quanto costa?

low-cost transmitters

Nome Costo Tempi Affdabilità

Estimote 99$ x 3 (33$ each) Late December *****

BLE Mini 30£ each Weeks ****

Alibaba seller 10$-20$ Days/Week ***

iBeacons: come lo uso?

❖Monitoring!❖Notify

iBeacons: Monitoring_locationManager = [[CLLocationManager alloc] init]; _locationManager.delegate = self; CLBeaconRegion *region = nil; _uuid = [[NSUUID alloc] initWithUUIDString:@“E2C56DB5-DFFB-48D2-B060-D0F5A71096E0"]; region = [[CLBeaconRegion alloc] initWithProximityUUID:_uuid identifier:@"com.apple.AirLocate"]; [_locationManager startRangingBeaconsInRegion:region]; !!- (void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region { !! NSLog(@"Major: %@, Minor: %@, Acc: %.2fm %li", beacon.major, beacon.minor, beacon.accuracy, beacon.proximity); !}

NSNumber *major = @2; NSNumber *minor = @2; region = [[CLBeaconRegion alloc] initWithProximityUUID:_uuid major:[major shortValue] minor:[minor shortValue] identifier:@"com.apple.AirLocate"];

iBeacons: Notify
