Comment associer un appareil Bluetooth à Android

Comment puis-je éviter ou rejeter la notification d'appariement Bluetooth D'Android lorsque je fais l'appariement programmatique?

cela semble vous donner la réponse, avec la broche entrant et tout. Il implique l'envoi .setPin () à chaque fois que vous recevez le message.

donc, j'ai eu cette question, si quelqu'un a besoin de la réponse à ce travail sur android 4.4.2.

 IntentFilter filter = new IntentFilter(
                "android.bluetooth.device.action.PAIRING_REQUEST");


        /*
         * Registering a new BTBroadcast receiver from the Main Activity context
         * with pairing request event
         */
        registerReceiver(
                new PairingRequest(), filter);

et le code du récepteur.

  public static class PairingRequest extends BroadcastReceiver {
        public PairingRequest() {
            super();
        }

        @Override
        public void onReceive(Context context, Intent intent) {
            if (intent.getAction().equals("android.bluetooth.device.action.PAIRING_REQUEST")) {
                try {
                    BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
                    int pin=intent.getIntExtra("android.bluetooth.device.extra.PAIRING_KEY", 0);
                    //the pin in case you need to accept for an specific pin
                    Log.d("PIN", " " + intent.getIntExtra("android.bluetooth.device.extra.PAIRING_KEY",0));
                    //maybe you look for a name or address
                    Log.d("Bonded", device.getName());
                    byte[] pinBytes;
                    pinBytes = (""+pin).getBytes("UTF-8");
                    device.setPin(pinBytes);
                    //setPairing confirmation if neeeded
                    device.setPairingConfirmation(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
    }

et dans le manifeste.

<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />

et le diffuseur.

 <receiver android:name=".MainActivity$PairingRequest">
                <intent-filter>
                    <action android:name="android.bluetooth.device.action.PAIRING_REQUEST" />
                    <action android:name="android.bluetooth.device.action.PAIRING_CANCEL" />
                </intent-filter>
</receiver>

essayez ce code:

public void pairDevice(BluetoothDevice device)
{
    String ACTION_PAIRING_REQUEST = "android.bluetooth.device.action.PAIRING_REQUEST";
    Intent intent = new Intent(ACTION_PAIRING_REQUEST);
    String EXTRA_DEVICE = "android.bluetooth.device.extra.DEVICE";
    intent.putExtra(EXTRA_DEVICE, device);
    String EXTRA_PAIRING_VARIANT = "android.bluetooth.device.extra.PAIRING_VARIANT";
    int PAIRING_VARIANT_PIN = 0;
    intent.putExtra(EXTRA_PAIRING_VARIANT, PAIRING_VARIANT_PIN);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(intent);
}

Intent intent = new Intent(BluetoothDevice.ACTION_PAIRING_REQUEST);
intent.putExtra(EXTRA_DEVICE, device);
int PAIRING_VARIANT_PIN = 272;
intent.putExtra(BluetoothDevice.EXTRA_PAIRING_VARIANT, PAIRING_VARIANT_PIN);
sendBroadcast(intent);

Intent intent = new Intent(Settings.ACTION_BLUETOOTH_SETTINGS);
startActivityForResult(intent, REQUEST_PAIR_DEVICE);

j'espère que cette aide

Essayez cette,

BluetoothDevice device = intent.getParcelableExtra("android.bluetooth.device.extra.DEVICE");
device.getClass().getMethod("setPairingConfirmation", boolean.class).invoke(device, true);
device.getClass().getMethod("cancelPairingUserInput", boolean.class).invoke(device);

    BluetoothSocket bluetoothSocket = null;
    try {
        bluetoothSocket = device.createRfcommSocketToServiceRecord(UUID.fromString(UUID_DIVING));
    } catch (IOException e) {
        Log.i("Bluetooth", "IOException = " + e.getMessage());
        e.printStackTrace();
    }

    try {
        byte[] pin = (byte[]) BluetoothDevice.class.getMethod("convertPinToBytes", String.class).invoke(BluetoothDevice.class, "0000");
        Method m = device.getClass().getMethod("setPin", byte[].class);
        m.invoke(device, (Object) pin);
        device.getClass().getMethod("setPairingConfirmation", boolean.class).invoke(device, true);
    } catch (IllegalAccessException | InvocationTargetException | NoSuchMethodException e) {
        Log.i("Bluetooth", "IOException = " + e.getMessage());
        e.printStackTrace();
    }

    try {
        if (bluetoothSocket != null) {
            bluetoothSocket.connect();
            Log.i("Bluetooth", "bluetoothSocket.connect() ");
            InputStream inputStream = bluetoothSocket.getInputStream();
            OutputStream outputStream = bluetoothSocket.getOutputStream();
        }
    } catch (IOException e) {
        e.printStackTrace();
    }

Comment définir le code pin a été répondu ci-dessus (et qui m'a aidé). Pourtant, je partage mon code simple ci-dessous qui fonctionne avec Android 6:

BluetoothAdapter mBTA = BluetoothAdapter.getDefaultAdapter();
if (mBTA.isDiscovering()) mBTA.cancelDiscovery();
mBTA.startDiscovery();
...

/** In a broadcast receiver: */

if (BluetoothDevice.ACTION_FOUND.equals(action)) { // One device found.

    BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
    Log.d(TAG, "Start Pairing... with: " + device.getName());
    device.createBond();
}

// If you want to auto-input the pin#:
else if (BluetoothDevice.ACTION_PAIRING_REQUEST.equals(action)){

                    BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
                    device.setPin("1234".getBytes());
}
