我试图在没有用户交互的情况下配对蓝牙(BLE)设备 - 意味着配对将仅以编程方式完成，用户不会选择蓝牙设备而不会输入密码 . 我正在使用以下代码：

//request receiver

IntentFilter pairingRequestFilter = new

IntentFilter(BluetoothDevice.ACTION_PAIRING_REQUEST);

pairingRequestFilter.setPriority(IntentFilter.SYSTEM_HIGH_PRIORITY - 1);

this.registerReceiver(mPairingRequestRecevier, pairingRequestFilter);

BluetoothManager bluetoothManager = (BluetoothManager)

this.getSystemService(Context.BLUETOOTH_SERVICE);

BluetoothAdapter bluetoothAdapter = bluetoothManager.getAdapter();

BluetoothDevice mDevice = bluetoothAdapter.getRemoteDevice("macaddress");

mDevice.setPairingConfirmation(true);

mDevice.setPin("1234".getBytes());

mDevice.createBond();

private final BroadcastReceiver mPairingRequestRecevier = new

BroadcastReceiver()

{
