altbeacon api를 사용하여 탐지 된 비콘이 없음

Question

하나의 iPhone은 locate 응용 프로그램을 사용하여 ibeacon을 전송하는 데 사용됩니다 (근접 uuid는 2F234454-CF6D-4A0F-ADF2-F4911BA9FFA6 임). 안드로이드 폰은 ibeacon을 감지하는 데 사용됩니다.

08-30 15 : 33 : 나는 디버깅 할 때 , 나는 다음과 같은 메시지가 얻을 수 있습니다 57.051 D/BluetoothLeScanner을 (27939) : onScanResult() - ScanResult {mDevice = 6D : CC : 9D : 8D : 3A : F3, mScanRecord = ScanRecord [mAdvertiseFlags = 26, mServiceUuids = null, mManufacturerSpecificData = {76 = [2,21,47,35,68,84, -49, 109, 74, 15, -83, -14, -12 0, 0, -59]}, mServiceData = {}, mTxPowerLevel = -2147483648, mDeviceName = null], mRssi = -31, mTimestampNanos = -111, 27, -87, -1, -90, 58705755631306}

그러나 기능이 RangingBeaconsInRegion 인 경우에는 비컨이 없습니다. 당신이 beaconParsers을 설정하는 코드를 자세히 보면

public class MainActivity : XFormsApplicationDroid, IBeaconConsumer 
     { 
      public MainActivity() 
      { 

      } 
      protected override void OnCreate(Bundle bundle) 
      { 

       BeaconManager beaconManager = BeaconManager.GetInstanceForApplication(this); 
       var iBeaconParser = new BeaconParser(); 

       iBeaconParser.SetBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"); 
       var parser = new BeaconParser(); 
       parser.SetBeaconLayout("m:2-3=beac,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"); 
       beaconManager.BeaconParsers.Add(parser); 

       beaconManager.Bind(this); 
    } 

    public void OnBeaconServiceConnect() 
      { 
       //obtain the beaconservie object of android 
       var beaconService = Xamarin.Forms.DependencyService.Get<IbeaconService>(); 
       beaconService.InitializeService(); 
       //beaconService.StartTransmitting(); 
       beaconService.StartMonitoring(); 
       beaconService.StartRanging(); 
      } 

    public void InitializeService() 
      { 
       m_beaconManager = InitializeBeaconManager(); 
      } 

    private BeaconManager InitializeBeaconManager() 
      { 
     BeaconManager bm =  BeaconManager.GetInstanceForApplication(Xamarin.Forms.Forms.Context); 

       //set the scan window 
       bm.SetForegroundScanPeriod(1100L); 

       //subscribe to the events; 
       m_monitorNotifier.EnterRegionComplete += EnteredRegion; 
       m_monitorNotifier.ExitRegionComplete += ExitedRegion; 
       m_monitorNotifier.DetermineStateForRegionComplete += DeterminedStateForRegionComplete; 
       m_rangeNotifier.DidRangeBeaconsInRegionComplete += RangingBeaconsInRegion; 


       // constructs a new region object to be used for ranging or monitoring 
       m_tagRegion = new Region("myUniqueBeaconId", Identifier.Parse("E4C8A4FC-F68B-470D-959F-29382AF72CE7"), null, null); 
       m_tagRegion = new Region("myUniqueBeaconId", Identifier.Parse("B9407F30-F5F8-466E-AFF9-25556B57FE6D"), null, null); 
       m_tagRegion = new Region("myUniqueBeaconId", Identifier.Parse("2F234454-CF6d-4A0F-ADF2-F4911BA9FFA6"), null, null); 
       m_emptyRegion = new Region("myEmptyBeaconId", null, null, null); 

       bm.SetBackgroundMode(false); 
       // 
       //bm.Bind((IBeaconConsumer)Xamarin.Forms.Forms.Context); 

       return bm; 
      } 

public void StartRanging() 
      { 
      BeaconManagerInstance.SetForegroundBetweenScanPeriod(0L); 
      m_beaconManager.AddRangeNotifier(m_rangeNotifier); 
      m_beaconManager.StartRangingBeaconsInRegion(m_tagRegion); 
      m_beaconManager.StartRangingBeaconsInRegion(m_emptyRegion); 

      } 

Answer 1

, 당신은 두 개의 구성되어 있음을 볼 수 있지만 하나 같이 추가됩니다

void RangingBeaconsInRegion(object sender, RangeEventArgs e) 
    { 
      await ClearData(); 
      var allBeacons = new List<Beacon>(); 
      if (e.Beacons.Count > 0) 
      { 
       foreach (var b in e.Beacons) 
       { 
         allBeacons.Add(b); 
         int rssi = b.Rssi; 
         System.Diagnostics.Debug.WriteLine(rssi.ToString()); 
        } 

         var orderedBeacons = allBeacons.OrderBy(b => b.Distance).ToList(); 
         await UpdateData(orderedBeacons); 
        } 
        else 
        { 
         // unknown 
         await ClearData(); 
        } 
       } 

다음

내 구현 한 것입니다 :

beaconManager.BeaconParsers.Add(parser); 

두 번째 호출을 추가하여 다른 신호 파서를 추가하면 문제가 해결됩니다.

Answer 2

고마워, 그건 내 실수 야! 다른 비컨 파서를 추가하기 위해 두 번째 호출을 추가 한 후! 여전히 어떤 이상한 상황이 있습니다 : 나는 어떤 비콘 송신기도 시작하지 않았지만 디버깅 할 때 D/BluetoothLeScanner (6864) : onScanResult() - ScanResult {mDevice = 58 : D6 : 74 : 3A : 34 : C5, mScanRecord = ScanRecord [mAdvertiseFlags = 6, mServiceUuids = null, mManufacturerSpecificData = {76 = [12,14,0,126,81,116, -16, 10, 52, 84, 15, 98, 113, 29, D/BluetoothLeScanner (6864) : onScanResult() {0, -15, 34}}, mServiceData = {}, mTxPowerLevel = -2147483648, mDeviceName = null, mRssi = -89, mTimestampNanos = 122142418198514} 08-31 09 : 11 : 13.943 - ScanRecult [mAdvertiseFlags = 6, mServiceUuids = null, mManufacturerSpecificData = {76 = [12, 14, 0, 126, 81, 116, -16, 10, 52, 84, 15, 98, 113, 29, -15, 34]}, mServiceData = {}, mTxPowerLevel = -2147483648, mDeviceName = null], mRssi = -89, mTimestampNanos = 122142560625598}. 하나의 신호가 감지 된 것 같습니다.
