Android的，怎樣才能讓BLE裝置配對設備（保稅）

Question

GATT之前， createRfcommSocketToServiceRecord， createInsecureRfcommSocketToServiceRecord

方法可以使配對設備，

但關貿總協定只沒有關於配對設備選項， 使用BluetoothDevice.connectGatt（...）

如果已經連接，我想配對設備。

thx。

據我所知，以啓動BLE配對過程有兩種方式：

1）從19 API和高達你可以通過調用mBluetoothDevice.createBond()開始配對。您無需連接遠程BLE設備即可開始配對過程。

2）當試圖做蓋特操作，讓我們例如該方法

mBluetoothGatt.readCharacteristic(characteristic) 

如果遠程BLE設備需要被結合做任何通信然後回調時

onCharacteristicRead( BluetoothGatt gatt, BluetoothGattCharacteristic characteristic, int status)

被稱爲其status參數值將等於GATT_INSUFFICIENT_AUTHENTICATION或GATT_INSUFFICIENT_ENCRYPTION，而不等於GATT_SUCCESS。如果發生這種情況，配對程序將自動開始。

這裏是要找出失敗時一旦onCharacteristicRead回調函數被調用

@Override 
public void onCharacteristicRead(
     BluetoothGatt gatt, 
     BluetoothGattCharacteristic characteristic, 
     int status) 
{ 

    if(BluetoothGatt.GATT_SUCCESS == status) 
    { 
     // characteristic was read successful 
    } 
    else if(BluetoothGatt.GATT_INSUFFICIENT_AUTHENTICATION == status || 
      BluetoothGatt.GATT_INSUFFICIENT_ENCRYPTION == status) 
    { 
     /* 
     * failed to complete the operation because of encryption issues, 
     * this means we need to bond with the device 
     */ 

     /* 
     * registering Bluetooth BroadcastReceiver to be notified 
     * for any bonding messages 
     */ 
     IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_BOND_STATE_CHANGED); 
     mActivity.registerReceiver(mReceiver, filter); 
    } 
    else 
    { 
     // operation failed for some other reason 
    } 
} 

其他人提的是，該操作將自動啓動配對過程爲例： Android Bluetooth Low Energy Pairing

這是怎麼了接收器可以實現

private final BroadcastReceiver mReceiver = new BroadcastReceiver() 
{ 
    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     final String action = intent.getAction(); 

     if (action.equals(BluetoothDevice.ACTION_BOND_STATE_CHANGED)) 
     { 
      final int state = intent.getIntExtra(BluetoothDevice.EXTRA_BOND_STATE, BluetoothDevice.ERROR); 

      switch(state){ 
       case BluetoothDevice.BOND_BONDING: 
        // Bonding... 
        break; 

       case BluetoothDevice.BOND_BONDED: 
        // Bonded... 
        mActivity.unregisterReceiver(mReceiver); 
        break; 

       case BluetoothDevice.BOND_NONE: 
        // Not bonded... 
        break; 
      } 
     } 
    } 
};
