2. Como implementar localização?

3. Como implementar localização?
Wifi Satélite Rede móvel Bluetooth

4. O que é um beacon BLE?

11. O que é um beacon BLE?
• Dispositivo por localização por bluetooth
• 2.4 Ghz, mas em canal diferente
• Certa capacidade de guardar informações
• ˜30bytes
• Bateria que pode durar anos
• Broadcast de uma a dez vezes por segundo

26. Eddystone
• Padrão open-source
• ID
• URL
• Ephemeral IDs
• Dados de telemetria
• Broadcast menos frequente que o iBeacon

34. Android:
MesssageFilter.Builder messageFilterBuilder = new MessageFilter.Builder()

35. Android:
MesssageFilter.Builder messageFilterBuilder = new MessageFilter.Builder()
// Include messages published by this app.
.includeAllMyTypes()
// Include messages of a specific type, published by nearby beacons.
.includeNamespacedType("com.google.location.beaconservice", "sample_attachment");
messageFilterBuilder.includeDevicePresenceMessages(
NearbyDeviceFilter.forEddystone(MY_EDDYSTONE_NAMESPACE))

36. Android:
MesssageFilter.Builder messageFilterBuilder = new MessageFilter.Builder()
// Include messages published by this app.
.includeAllMyTypes()
// Include messages of a specific type, published by nearby beacons.
.includeNamespacedType("org.example.beaconinfoeservice", "sample_attachment");
messageFilterBuilder.includeDevicePresenceMessages(
NearbyDeviceFilter.forEddystone(MY_EDDYSTONE_NAMESPACE))
SubscribeOptions options = new SubscribeOptions.Builder()
.setStrategy(getStrategy())
.setFilter(messageFilterBuilder.build())
.build();
Nearby.Messages.subscribe(mGoogleApiClient, mMessageListener, options)
.setResultCallback(new ErrorCheckingCallback("subscribe(MessageListener)"));

37. iOS:
GNSStrategy *beaconStrategy

38. iOS:
GNSStrategy *beaconStrategy = [GNSStrategy
strategyWithParamsBlock:^(GNSStrategyParams *params) {
params.includeBLEBeacons = YES;
}];

39. iOS:
GNSStrategy *beaconStrategy = [GNSStrategy
strategyWithParamsBlock:^(GNSStrategyParams *params) {
params.includeBLEBeacons = YES;
}];
GNSSubscriptionParams *beaconParams = [GNSSubscriptionParams
paramsWithMessageNamespace:@“com.mycompany.mybeaconservice”
type:@“mybeacontype”
strategy:beaconStrategy];
_beaconSubscription = [_messageManager subscriptionWithParams:beaconParams
messageFoundHandler:myMessageFoundHandler
messageLostHandler:myMessageLostHandler];
