Ble配對失敗

Question

我參與了一個Android APP，它與我們公司Bt芯片進行BLE連接和配對。 APP是BLE的中心角色，而Bt芯片則是BLE外設。

當APP在Android 4.4或5.0智能手機上運行時，BLE連接和配對效果良好。當APP在Android 5.1或最新版本6.0上運行時，BLE配對由錯誤代碼（錯誤代碼：13）終止，而BLE連接成功。這裏是空氣日誌：

我轉Bt基因宿主程序（基於轉Bt基因芯片）收到CONNECTION_PARAMETER_UPDATE_COMP_IND事件，然後收到LE_DEVICE_DISCONNECT_COMP_IND事件。我想斷開BLE的操作是由Android Bt堆棧完成的。

在Android 4.4或5.0中，沒有收到CONNECTION_PARAMETER_UPDATE_COMP_IND事件，那麼有什麼關係呢，我怎麼才能在Android 5.1或6.0上使BLE配對成功。任何幫助將不勝感激。

Answer 1

對於藍牙低功耗設備發現和配對有兩種方法被支持

1. 對於奇巧版本及以下

   startLeScan() 
   

這種方法需要一個BluetoothAdapter。 LeScanCallback作爲參數

對於棒棒糖版本及以上

mBluetoothLeScanner = mBluetoothAdapter.getBluetoothLeScanner(); 

mBluetoothLeScanner.startScan(filters, settings, mScanCallback); 

，你需要確定你的回調爲流得到響應

private ScanCallback mScanCallback = new ScanCallback() { 
@Override 
public void onScanResult(int callbackType, ScanResult result) { 

} 

@Override 
public void onBatchScanResults(List<ScanResult> results) { 

} 

@Override 
public void onScanFailed(int errorCode) { 

} 
}; 

Answer 2

感謝你的回覆。我嘗試使用startScan方法而不是startLeScan，但問題仍然存在。這裏是代碼的一部分：

mBluetoothScanner = mBluetoothAdapter.getBluetoothLeScanner(); 
    mBluetoothScanner.startScan(mScanCallback); 
    private ScanCallback mScanCallback = new ScanCallback() { 
    @Override 
    public void onScanResult(int callbackType, ScanResult result) { 
     final byte[] scanRecord = result.getScanRecord().getBytes(); 
     final int rssi = result.getRssi(); 
     final BluetoothDevice device = result.getDevice(); 

     mHandler.post(new Runnable() { 
      @Override 
      public void run() { 
       // TODO Auto-generated method stub 
       //Application analyzes data in received packet. 
       AdvertisingData adData = new AdvertisingData(scanRecord); 
       byte[] adManufacturerData = adData.getAdManufacturerData(); 
       if (adManufacturerData.length < 2) {return;} 

       byte[] carBrand = Arrays.copyOf(adManufacturerData, adManufacturerData.length - 2); 
       byte[] carModel = Arrays.copyOfRange(adManufacturerData, adManufacturerData.length - 2, adManufacturerData.length); 
       if (!Arrays.equals(carBrand, mManufacturerData)) {return;} 

       mScanningFrame.setRssiInfo(rssi); 

       if (rssi >= mRssi) { 
        mConnectingFrame.setCarImage(carModel); 
        mConnectedFrame.setCarImage(carModel); 
        mDisconnectedFrame.setCarImage(carModel); 
        try { 
         Thread.sleep(1000); 
        } catch (Exception e) { 
         e.printStackTrace(); 
        } 
        showFrame(mConnectingFrame); 
        mBleDevice = device; 
        mBluetoothGatt = mBleDevice.connectGatt(getApplicationContext(), false, mGattCallback); 
        mBluetoothAdapter.stopLeScan(mLeScanCallback); 
       } 
      } 
     }); 
    } 

    @Override 
    public void onBatchScanResults(List<ScanResult> results) { 

    } 

    @Override 
    public void onScanFailed(int errorCode) { 

    } 
}; 

還有其他方法可以解決這個問題，或者我錯過了什麼？謝謝
