上一篇博客介绍了Android ble的一些情况。

蓝牙如果链接好，能够读写，基本上完成了。蓝牙还有个比较烦人的东西，就是蓝牙配对。
Android ble4.0使用的配对方式和原先版本的配对方式不一样。
看了网上很多地方都是hellogv大神的方法，这个真心不错。

本着认真的态度，我把Android系统中Settings的源码给研究了下，发现了配对的流程，Settings的源码大小大概有300m，考虑的攻击
Ble4.0的配对界面有2个部分，首先的是一个请求的配对的通知，点击了是一个确认对话框，再点击，然后又有个通知，点击通知后，有个输入密码的的对话框，输入密码后，点确定，稍后就会有配对的结果。
下面是Settings中的源码
Settings的目录是/package/app/Settings，下面是Setting的源码url，感兴趣的同学可以去研究下
http://git.omapzoom.org/ 所有的源码网址
http://git.omapzoom.org/?p=platform/packages/apps/Settings.git;a=summary Settings的网址
git://git.omapzoom.org/platform/packages/apps/Settings.git Settings的git地址
Settings中的蓝牙代码都在/Settings/src/com/android/settings/bluetooth目录中
主要流程看下面的文件
/Settings/src/com/android/settings/bluetooth/BluetoothPairingDialog.java
代码中很多的类，在实际的Android应该开发中是没有的，我这边准备了三个jar文件，分别是framework.jar,core.jar,ext.jar，这些事Android系统编译的时候，生产的jar。
导入到elcipse中，关联此jar就可以。关联的jar时放在libs中，但是有个必须注意的地方，点击项目的属性，在Java BuildPath类别，Order and Export标签，Android Dependenceis必须要比Android 5.0的在上面，这样在引用的时候，就会优先引用Android Dependceis中的jar。
下面是Setting中的BluetoothPairingDialog.java，简单分析下，中文部分是我添加的注释。

当收到请求配对的广播后，此对话框会显示。
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // 必须是ACTION_PAIRING_REQUEST，否则不运行,ACTION_PAIRING_REQUEST是一个请求的配对的广播 Intent intent = getIntent(); if (!intent.getAction().equals(BluetoothDevice.ACTION_PAIRING_REQUEST是一个请求的配对的广播)) { Log.e(TAG, "Error: this activity may be started only with intent " + BluetoothDevice.ACTION_PAIRING_REQUEST); finish(); return; } LocalBluetoothManager manager = LocalBluetoothManager.getInstance(this); if (manager == null) { Log.e(TAG, "Error: BluetoothAdapter not supported by system"); finish(); return; } CachedBluetoothDeviceManager deviceManager = manager.getCachedDeviceManager(); // 获取配对的设备和配对类型，我的项目中配对类型是BluetoothDevice.PAIRING_VARIANT_PIN mDevice = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); mType = intent.getIntExtra(BluetoothDevice.EXTRA_PAIRING_VARIANT, BluetoothDevice.ERROR); // 根据配对的类型，进行分发,我们重点关注PAIRING_VARIANT_PIN switch (mType) { case BluetoothDevice.PAIRING_VARIANT_PIN: case BluetoothDevice.PAIRING_VARIANT_PASSKEY: // 创建用户输入配对密码的对话框 createUserEntryDialog(deviceManager); break; case BluetoothDevice.PAIRING_VARIANT_PASSKEY_CONFIRMATION: int passkey = intent.getIntExtra(BluetoothDevice.EXTRA_PAIRING_KEY, BluetoothDevice.ERROR); if (passkey == BluetoothDevice.ERROR) { Log.e(TAG, "Invalid Confirmation Passkey received, not showing any dialog"); return; } mPairingKey = String.format(Locale.US, "%06d", passkey); createConfirmationDialog(deviceManager); break; case BluetoothDevice.PAIRING_VARIANT_CONSENT: case BluetoothDevice.PAIRING_VARIANT_OOB_CONSENT: createConsentDialog(deviceManager); break; case BluetoothDevice.PAIRING_VARIANT_DISPLAY_PASSKEY: case BluetoothDevice.PAIRING_VARIANT_DISPLAY_PIN: int pairingKey = intent.getIntExtra(BluetoothDevice.EXTRA_PAIRING_KEY, BluetoothDevice.ERROR); if (pairingKey == BluetoothDevice.ERROR) { Log.e(TAG, "Invalid Confirmation Passkey or PIN received, not showing any dialog"); return; } if (mType == BluetoothDevice.PAIRING_VARIANT_DISPLAY_PASSKEY) { mPairingKey = String.format("%06d", pairingKey); } else { mPairingKey = String.format("%04d", pairingKey); } createDisplayPasskeyOrPinDialog(deviceManager); break; default: Log.e(TAG, "Incorrect pairing type received, not showing any dialog"); } /* * Leave this registered through pause/resume since we still want to * finish the activity in the background if pairing is canceled. */ // 注册广播 registerReceiver(mReceiver, new IntentFilter(BluetoothDevice.ACTION_PAIRING_CANCEL)); registerReceiver(mReceiver, new IntentFilter(BluetoothDevice.ACTION_BOND_STATE_CHANGED)); } 2、创建有输入框的界面
// 创建用户输入配对密码的对话框 private void createUserEntryDialog(CachedBluetoothDeviceManager deviceManager) { // 创建对话框的界面， // 在看看对话框的确定的回调函数，由于本类是实现DialogInterface.OnClickListener的方法的，我们可以去看下 // public void onClick(DialogInterface dialog, int which) final AlertController.AlertParams p = mAlertParams; p.mIconId = android.R.drawable.ic_dialog_info; p.mTitle = getString(R.string.bluetooth_pairing_request); p.mView = createPinEntryView(deviceManager.getName(mDevice)); p.mPositiveButtonText = getString(android.R.string.ok); p.mPositiveButtonListener = this; p.mNegativeButtonText = getString(android.R.string.cancel); p.mNegativeButtonListener = this; setupAlert(); mOkButton = mAlert.getButton(BUTTON_POSITIVE); mOkButton.setEnabled(false); } 3、查看输入框的确定回调函数
// 对话框的确定的回调 public void onClick(DialogInterface dialog, int which) { switch (which) { case BUTTON_POSITIVE: // 进行配对 if (mPairingView != null) { onPair(mPairingView.getText().toString()); } else { onPair(null); } break; case BUTTON_NEGATIVE: default: onCancel(); break; } } 4、配对
// 进行配对 private void onPair(String value) { // 根据类型进行分发 switch (mType) { case BluetoothDevice.PAIRING_VARIANT_PIN: // 注意这里是用了转换的方法，不是直接调用value.getBytes();方法 byte[] pinBytes = BluetoothDevice.convertPinToBytes(value); if (pinBytes == null) { return; } // 直接调用setPin方法,然后就没有了，等到收到状态改变的广播后就进行dismiss,请看54行的mReceiver mDevice.setPin(pinBytes); break; case BluetoothDevice.PAIRING_VARIANT_PASSKEY: int passkey = Integer.parseInt(value); mDevice.setPasskey(passkey); break; case BluetoothDevice.PAIRING_VARIANT_PASSKEY_CONFIRMATION: case BluetoothDevice.PAIRING_VARIANT_CONSENT: mDevice.setPairingConfirmation(true); break; case BluetoothDevice.PAIRING_VARIANT_DISPLAY_PASSKEY: case BluetoothDevice.PAIRING_VARIANT_DISPLAY_PIN: // Do nothing. break; case BluetoothDevice.PAIRING_VARIANT_OOB_CONSENT: mDevice.setRemoteOutOfBandData(); break; default: Log.e(TAG, "Incorrect pairing type received"); } } // 注意这里是用了转换的方法，不是直接调用value.getBytes();方法
byte[] pinBytes = BluetoothDevice.convertPinToBytes(value);
下面是系统的中的配对密码转换
/** * Check that a pin is valid and convert to byte array. * * Bluetooth pin's are 1 to 16 bytes of UTF-8 characters. * @param pin pin as java String * @return the pin code as a UTF-8 byte array, or null if it is an invalid * Bluetooth pin. * @hide */ public static byte[] convertPinToBytes(String pin) { if (pin == null) { return null; } byte[] pinBytes; try { pinBytes = pin.getBytes("UTF-8"); } catch (UnsupportedEncodingException uee) { Log.e(TAG, "UTF-8 not supported?!?"); // this should not happen return null; } if (pinBytes.length <= 0 || pinBytes.length > 16) { return null; } return pinBytes; }
private final BroadcastReceiver mReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if (BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals(action)) { // 当设备的配对状态改变的时候，就把对话框去掉 int bondState = intent.getIntExtra(BluetoothDevice.EXTRA_BOND_STATE, BluetoothDevice.ERROR); if (bondState == BluetoothDevice.BOND_BONDED || bondState == BluetoothDevice.BOND_NONE) { dismiss(); } } else if (BluetoothDevice.ACTION_PAIRING_CANCEL.equals(action)) { BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); if (device == null || device.equals(mDevice)) { dismiss(); } } } }; 以上就是系统的设置的配对流程。
下面是自己的项目中的业务代码
BroadcastReceiver bleReceiver = new BroadcastReceiver() { public void onReceive(Context context, Intent intent) { McLog.mByStackTrace(); String action = intent.getAction(); McLog.i("action = " + action); if (BluetoothDevice.ACTION_FOUND.equals(action)) {// 搜索设备 doDeviceSearch(intent); } else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) { //搜索结束 doDeviceSearchFinished(intent); } else if (BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals(action)) { // 设备状态改变 doStateChange(intent); } else if (BluetoothDevice.ACTION_PAIRING_REQUEST.equals(action)) {// 请求匹配 doRequestPari(intent); } } void doStateChange(Intent intent) { BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); switch (device.getBondState()) { case BluetoothDevice.BOND_NONE: McLog.i("取消配对"); break; case BluetoothDevice.BOND_BONDING: McLog.i("正在配对......"); break; case BluetoothDevice.BOND_BONDED: McLog.i("完成配对"); break; } } void doDeviceSearch(Intent intent) { BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); McLog.i("device = " + device); if (device.getBondState() == BluetoothDevice.BOND_BONDED) {// 已经配对的则跳过 } else { if (!searchDevices.contains(searchDevices)) { searchDevices.add(device); } } } void doDeviceSearchFinished(Intent intent) { McLog.i("search finished, searchDevices's size = " + searchDevices.size()); boolean isFindRightDevice = false; for (BluetoothDevice device : searchDevices) { if (isRightDevice(device)) { // 如果是我想要的设备，那么我就进行配对 doNormalPair(device); isFindRightDevice = true; break; } } if (!isFindRightDevice) { McLog.i("sorry,do't search user's device[" + bleDeviceMac + "]"); } } void doNormalPair(BluetoothDevice device) { McLog.mByStackTrace(); currentPairDevice = device; try { // 调用配对的方法，此方法是异步的，系统会触发BluetoothDevice.ACTION_PAIRING_REQUEST的广播 // 收到此广播后，设置配对的密码 ClsUtils.createBond(BluetoothDevice.class, currentPairDevice); } catch (Exception e) { e.printStackTrace(); } } void doRequestPari(Intent intent) { BluetoothDevice btDevice = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); if (btDevice.getBondState() == BluetoothDevice.BOND_BONDED) { McLog.e("已经绑定"); } else { McLog.e("没有绑定"); if (currentPairDevice != null && btDevice.getAddress().equalsIgnoreCase(currentPairDevice.getAddress())) { try { McLog.i("invoke setpin :" + bleDeviceMac); // 设置配对的密码 <span style="font-family: Arial, Helvetica, sans-serif;">bleDevicePasswd 设备的配对密码</span> ClsUtils.setPin2(BluetoothDevice.class, currentPairDevice, bleDevicePasswd); } catch (Exception e) { McLog.i("e = " + e); } currentPairDevice = null; uiHandler.postDelayed(new Runnable() { public void run() { loadBleData(); // 注销监听 unregisterReceiver(bleReceiver); } }, 1000); } } } };
以上就能完成ble4.0的密码自动配对，当然中间的对话框会显示1s左右时间，然后会再次消失。
