蓝牙连接，原因码= 0x000e-Android

仰天大笑出门去，我辈岂是蓬蒿人。这篇文章主要讲述蓝牙连接，原因码= 0x000e-Android相关的知识，希望能为你提供帮助。
我正在尝试创建一个连接/断开BLE设备的应用程序。我已经使用标准的android BT API创建了一个应用程序。这是我连接BLE设备的代码

try { Log.d(TAG, "Going to connect"); BluetoothDevice device = BluetoothAdapter.getDefaultAdapter().getRemoteDevice(macaddress); if (device.getBondState() == BluetoothDevice.BOND_BONDED) { Log.d(TAG, "Device is already bonded. try connecting it"); if (bluetoothGatt != null) { Log.d(TAG, "bluetoothGatt is not null. Just connect it"); bluetoothGatt.connect(); return; } bluetoothGatt = device.connectGatt(getApplicationContext(), false, gattCallback); bluetoothGatt.requestConnectionPriority(BluetoothGatt.CONNECTION_PRIORITY_HIGH); } else { Log.d(TAG, "Device is ? =====> " + device.getBondState() + " Create bond"); device.createBond(); } } catch (Exception ex) { Log.e(TAG, ex.toString()); }

****广播接收器****

private final BroadcastReceiver mPairingRequestRecevier = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { Log.d(TAG, "Intent action is: " + intent.getAction()); if (BluetoothDevice.ACTION_PAIRING_REQUEST.equals(intent.getAction())) { final BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); int type = intent.getIntExtra(BluetoothDevice.EXTRA_PAIRING_VARIANT, BluetoothDevice.ERROR); try { byte[] pinbytes; pinbytes = ("" + 1234).getBytes("UTF-8"); Log.d(TAG, "+_+_+_+_+_+_+_+_+Setting pin to : +_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_"); device.setPin(pinbytes); abortBroadcast(); } catch (Exception ex) { ex.printStackTrace(); }} else if (BluetoothDevice.ACTION_ACL_CONNECTED.equals(intent.getAction())) { runOnUiThread(new Runnable() { @Override public void run() { Toast.makeText(MainActivity.this, "BT Connected",Toast.LENGTH_SHORT).show(); } }); Log.d(TAG, "Device is connected"); } else if (BluetoothDevice.ACTION_ACL_DISCONNECTED.equals(intent.getAction())) { runOnUiThread(new Runnable() { @Override public void run() { Toast.makeText(MainActivity.this, "BT DisConnected",Toast.LENGTH_SHORT).show(); } }); Log.d(TAG, "Device is Disconnected"); } else if (BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals(intent.getAction())) { int state = intent.getIntExtra(BluetoothDevice.EXTRA_BOND_STATE, -1); switch (state) { case BluetoothDevice.BOND_NONE: Log.d(TAG, "The remote device is not bonded."); runOnUiThread(new Runnable() { @Override public void run() { Toast.makeText(MainActivity.this, "The remote device is not bonded",Toast.LENGTH_SHORT).show(); } }); break; case BluetoothDevice.BOND_BONDING: Log.d(TAG, "Bonding is in progress with the remote device."); break; case BluetoothDevice.BOND_BONDED: Log.d(TAG, "The remote device is bonded."); runOnUiThread(new Runnable() { @Override public void run() { Toast.makeText(MainActivity.this, "The remote device is bonded.",Toast.LENGTH_SHORT).show(); } }); BluetoothDevice device = BluetoothAdapter.getDefaultAdapter().getRemoteDevice(macaddress); bluetoothGatt = device.connectGatt(getApplicationContext(), false, gattCallback); bluetoothGatt.requestConnectionPriority(BluetoothGatt.CONNECTION_PRIORITY_HIGH); Log.d(TAG, "Connection done: " + bluetoothGatt); break; default: Log.d(TAG, "Unknown remote device bonding state."); break; } } } };

[当我尝试执行并连接设备时，它会连接，然后立即断开连接，原因码为0x000e。这是logcat的输出：

[当我检查原因码0x000e时，它说这是因为BT_HCI_OP_PIN_CODE_NEG_REPLY。但是我不知道为什么会出现原因代码？
提前感谢！Maulik
答案我找到了上述问题的解决方案。
问题是我称他为“ createBond”方法，因为我希望将其配对。但是我没有配对的设备只是简单地连接而不配对，所以我删除了配对代码，直接调用了gatt.connect（）方法。
