我正在使用 AltBeacon 构建应用程序 库支持 Onyx Beacons (Beacon One) Gimbal Beacons (Series 21)

我的测试设备是配备 Android 4.4.4 KitKat 和 Onyx Beacon 的 Nexus 7 2013。信标就在我的设备旁边不到一米的地方,我没有移动它。检测到信标并转到 didEnterRegion然后在一分钟左右后转到 didExitRegion然后循环重复。

我们还使用不同的 (Onyx) 信标在不同的设备(三星手机)上对此进行了测试。仍然出现问题。请注意,这仅发生在 Onyx Beacons (Beacon One)。 <强> Gimbal Beacons (Series 21) 仅在范围内触发一次。

我使用的 Beacon Parser 字符串是否正确?我是否正确实现了这一点?我真的没有想法,我想支持这两个信标。

基础应用

public class BaseApplication extends Application {

@Override
public void onCreate() {
super.onCreate();
startService(new Intent(this, BeaconMonitoringService.class));
}

}

BeaconMonitoringService

public class BeaconMonitoringService extends Service implements BeaconConsumer{

private Context context;

private BeaconService service;
private BeaconManager beaconManager;
private NotificationCompat.Builder notifBuilder;

@Override
public void onCreate(){
super.onCreate();
context = getBaseContext();
beaconManager = BeaconManager.getInstanceForApplication(this);
beaconManager.setBackgroundMode(true);

beaconManager.setBackgroundScanPeriod(1100l);
beaconManager.setBackgroundBetweenScanPeriod(15000l);

String[] beaconParsers = new String[] { "m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24", "m:2-3=beac,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25", "m:2-3=0203,i:14-19l,d:10-13,p:9-9" };

for(String beacon : beaconParsers){
Log.i("BeaconService","layout: "+beacon);
beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout(beacon));
}
beaconManager.bind(this);
}

@Override
public void onBeaconServiceConnect() {
beaconManager.setMonitorNotifier(new MonitorNotifier() {

private String log;

@Override
public void didEnterRegion(Region region) {
Beacon beacon = service.getBeacon(region.getId1().toString(), region.getId2().toString(), region.getId3().toString());
log = "I just saw a beacon for the first time! "+region.getId1()+" "+region.getId2()+" "+region.getId3();
Log.i("BeaconService", log);
sendNotification(beacon);
}

@Override
public void didExitRegion(Region region) {
Beacon beacon = service.getBeacon(region.getId1().toString(), region.getId2().toString(), region.getId3().toString());
log = "I no longer see a beacon";
Log.i("BeaconService", log);
}

@Override
public void didDetermineStateForRegion(int state, Region region) {

}
});

List<BackendRegion> regionList = Util.getRegionList();
for(BackendRegion region : regionList){
ArrayList<Beacon> beaconList = region.getBeacons();
for(Beacon beacon : beaconList){
try {
String beaconString = region.getUuid().toLowerCase() + " " + beacon.getMajor() + " " + beacon.getMinor();
service.addBeacon(beacon);
beaconManager.startMonitoringBeaconsInRegion(new Region(beacon.getIdentifier(), Identifier.parse(region.getUuid()),Identifier.parse(beacon.getMajor()),Identifier.parse(beacon.getMinor())));
} catch (RemoteException e) { }
}
}

}


@Override
public IBinder onBind(Intent intent) {
return null;
}

@Override
public void onDestroy(){
beaconManager.unbind(this);
super.onDestroy();
}

private void sendNotification(Beacon beacon, InteractiveImage interactiveImage) {
this.notifBuilder = new NotificationCompat.Builder(this)
.setAutoCancel(true)
.setContentTitle("Sample Beacon")
.setContentText("A beacon was detected")
.setSmallIcon(R.drawable.ic_launcher);

Intent notifyIntent = new Intent(this, NotificationActivity.class);
notifyIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_MULTIPLE_TASK);

PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notifyIntent, 0);
notifBuilder.setContentIntent(pendingIntent);

NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(Integer.parseInt(beacon.getId()), notifBuilder.build());

}

}

最佳答案

一些提示:

  • 检查 Onyx Beacon One 的广告率。为获得最佳效果,信标应以标准的 10Hz 进行广告。一些制造商降低了这种广告率以节省电池生命周期。如果您有一个以 1Hz 或更低频率进行广告的信标,它可能会开始被信标扫描仪定期遗漏。 (由于蓝牙 radio 噪声,并非 100% 的数据包都被检测到。)

  • 如果您发现广告频率为 1 Hz 或更低,请尽可能提高广告频率,问题应该会消失。

  • 如果你不能提高信标的广告率,你可以减慢Android Beacon Library的扫描率。 给它更多的时间来收集信标数据包。默认情况下,它使用 1.1 秒的扫描周期。您可以使用如下代码行将其减慢到 5 秒。这将更可靠地与不经常做广告的信标一起工作,但也会让您对区域进入/退出的响应时间变慢。 beaconManager.setForegroundScanPeriod(5000l);
