如何修复Android BLE SCAN_FAILED_APPLICATION_REGISTRATION_FAILED错误？

Question

大多数的时候，它的伟大工程，但有时我试图发现BLE装置有此错误：

02-12 18:00:41.967 16178-16178/com.icrealtime.allie E/BleRpcConnectionFactory﹕ BLE SCAN FAILED: 2 

错误代码2个代表https://developer.android.com/reference/android/bluetooth/le/ScanCallback.html#SCAN_FAILED_APPLICATION_REGISTRATION_FAILED

这似乎是Android的内部问题，但它可能会受到我的代码做错事情的影响。什么原因以及如何绕过它？

PS。 Nexus 9，Android 6.0.1

一种可能的解决方法，它可能是以编程方式禁用/启用蓝牙。当你有SCAN_FAILED_APPLICATION_REGISTRATION_FAILED应禁用BluetoothAdapter错误：

BluetoothAdapter.getDefaultAdapter().disable(); 

禁用BluetoothAdapter，事件STATE_TURNING_OFF被激发。一旦发生此事件，请尝试重新连接到BluetoothAdapter：

case BluetoothAdapter.STATE_OFF: 
    Log.d(TAG, "bluetooth adapter turned off"); 
    handler.postDelayed(new Runnable() { 
    @Override 
    public void run() { 
     Log.d(TAG, "bluetooth adapter try to enable"); 
     BluetoothAdapter.getDefaultAdapter().enable(); 
    }}, 500); 
    break;
