蓝牙配对谷歌玻璃 [英] Bluetooth Pairing Google Glass

问题描述

使用谷歌的玻璃，我能够发现蓝牙设备，看到他们的地址和信息。但是，我不能让玻璃以对（债券）与他们。

Using Google Glass, I am able to discover Bluetooth devices and see their address and information. However, I cannot get the Glass to pair (bond) with them.

继<一的说明href="http://www.londatiga.net/it/programming/android/how-to-programmatically-pair-or-unpair-android-bluetooth-device/"相对=nofollow>这个页面现在我试图让粘合，但由于某些原因， BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals（动作）从不发生的事情。

Following the instructions on this page now I'm trying to get the bonding, but for some reason the BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals(action) is never happening.

private void pairDevice(BluetoothDevice Ddevice) {
    Log.d("MY_LOG", "Try to pair " + Ddevice.getName());
    try{
        Method m = Ddevice.getClass().getMethod("createBond", (Class[]) null);
        m.invoke(Ddevice, (Object[]) null);
        Log.d("MY_LOG", "Pairing " + Ddevice.getName());
    }catch(Exception e){
        Log.d("MY_LOG", "Error: ");
        e.printStackTrace();
    }
}

在LOG我总是得到配对设备名称，但是当我搜索保税设备，但它仍然是空的。

In the LOG I always get "Pairing DeviceName" but when I search for the bonded devices, it remains empty.

任何帮助将大大AP preciated。

Any help will be greatly appreciated.

推荐答案

所以，我会回答我的问题，因为我刚刚发现的方法。

So I will answer my own question as I just found the way.

因此​​，首先，设备的发现是很容易的，在的onCreate（）我用（除所有其他种类的$ C $的c您所需要的）：

So first, the discovery of devices is quite easy, in onCreate() I used (besides all other sort of code you need):

MyBT = BluetoothAdapter.getDefaultAdapter();
MyBT.startDiscovery();
Filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);                    // Register the BroadcastReceiver
Filter2 = new IntentFilter(BluetoothDevice.ACTION_PAIRING_REQUEST);         // Register the Bond changing state
registerReceiver(mReceiver, Filter);                                        // Don't forget to unregister during onDestroy
registerReceiver(mReceiver, Filter2);                                       // ******

然后在的BroadcastReceiver 您需要管理的设备和配对请求：

Then at the BroadcastReceiver you need to manage the devices and the pairing requests:

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {           // Create a BroadcastReceiver for ACTION_FOUND
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();

        if (BluetoothDevice.ACTION_FOUND.equals(action)) {                      // When discovery finds a device
            BluetoothDevice BTdevice = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); // Get the BluetoothDevice object from the Intent
            ListDev.add(BTdevice);                                              // Add the device to an array adapter to show...
        }     
        if(BluetoothDevice.ACTION_PAIRING_REQUEST.equals(action)){
            BluetoothDevice device = ListDev.get(selectedDevice);
            byte[] pinBytes = getStrFromName(device.getName(),7,11).getBytes();  // My devices had their own pin in their name, you can put a constant pin here...  
            try {
                Log.d("MY_LOG", "Try to set the PIN");
                Method m = device.getClass().getMethod("setPin", byte[].class);
                m.invoke(device, pinBytes);
                Log.d("MY_LOG", "Success to add the PIN.");
                try {
                    device.getClass().getMethod("setPairingConfirmation", boolean.class).invoke(device, true);
                    Log.d("MY_LOG", "Success to setPairingConfirmation.");
                } catch (Exception e) {
                    Log.e("MY_LOG", e.getMessage());
                    e.printStackTrace();
                } 

            } catch (Exception e) {
                Log.e("MY_LOG", e.getMessage());
                e.printStackTrace();
            }
        }
    }
}; 

在该设备结合，您可以管理与UUID的连接和插座一样在Android的网页例如。

After that the device is bonded and you can manage the connection with the UUID and the sockets just as in the Android webpage example.
