有什么方法可以获取配对的蓝牙设备的配置文件。 我已经能够配对蓝牙设备并且它已配对为 INPUT_DEVICE 在 android 中,我得到了 BluetoothDevice 的对象,其中包含地址和其他内容,但是如果 android 存储了它的配置文件,那么我们可以从那里获取配对的设备配置文件,比如 HEADSET 或 A2DP 或 INPUT_DEVICE 或其他。
我已经尝试过service listener的方法
private BluetoothProfile.ServiceListener listener=new BluetoothProfile.ServiceListener() {
@Override
public void onServiceDisconnected(int profile) {
// TODO Auto-generated method stub
//if(profile==BluetoothProfile.HEADSET)
headSet=null;
}
@Override
public void onServiceConnected(int profile, BluetoothProfile proxy) {
// TODO Auto-generated method stub
switch(profile){
case BluetoothProfile.HEADSET:
Log.e("found","headset");
break;
case BluetoothProfile.A2DP:
Log.e("found","a2dp");
activity.onA2DPListenr((BluetoothA2dp) proxy);
break;
case BluetoothProfile.HEALTH:
Log.e("found","HEALTH");
break;
}
}
}
};
现在每当我调用它时
activity.getAdapter().getProfileProxy(activity, listener,
BluetoothProfile.HEADSET);
它会转到耳机日志,当我打电话时
activity.getAdapter().getProfileProxy(activity, listener,
BluetoothProfile.HEALTH);
它会转到健康日志,并显示配置文件已连接到同一设备。但同一设备可以同时成为两者。
我的要求也与此完全不同,我不想尝试不同的场景来找出 android 已经包含的配对设备的实际配置文件,他们有什么方法可以获取实际配置文件..?
最佳答案
可以通过以下方式找到与 BluetoothDevice 关联的蓝牙配置文件或服务
boolean hasLatestUuids=device.fetchUuidsWithSdp();
if(hasLatestUuids){
/*getUuids() return cached uuids so we need to make an sdp request to get refresh uuid associated with the device*/
ParcelUuid[] uu=device.getUuids();
for(ParcelUuid u:uu){
Log.e("found","uuid "+u.getUuid());
}
}
我们也可以通过反射发出请求:
Method m=null;
boolean hasLatestUuid=false;
try {
m=BluetoothDevice.class.getDeclaredMethod("fetchUuidsWithSdp", null);
m.setAccessible(true);
hasLatestUuid=(Boolean) m.invoke(device, null);
} catch (NoSuchMethodException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
ParcelUuid[] uuids=null;
if(hasLatestUuid){
try {
m=device.getClass().getDeclaredMethod("getUuids", null);
m.setAccessible(true);
uuids=(ParcelUuid[]) m.invoke(device, null);
} catch (NoSuchMethodException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if(uuids!=null){
for(ParcelUuid u:uuids){
Log.e("found","uuid "+u.describeContents());
Log.e("found","uuid "+u.getUuid());
}
}
此处日志返回远程设备支持的 uuid 列表,例如在我的情况下我需要连接到两个不同的设备,第一个具有 HID 配置文件,第二个具有串行端口或套接字,所以
对于串行端口设备,我得到 uuid:00001101-0000-1000-8000-00805f9b34fb
对于 HumanInterface,我得到 uuid:00001124-0000-1000-8000-00805f9b34fb
它有 bas_uuid:00000000-0000-1000-8000-00805F9B34FB 和串行端口:0x1101 和 HID:0x1124
所有这些信息都可以找到http://bluetooth-pentest.narod.ru/doc/assigned_numbers_-_service_discovery.html
我们也可以通过 BluetoothClass 检查这个,即
public static final int PROFILE_HEADSET = 0;
/** @hide */
public static final int PROFILE_A2DP = 1;
/** @hide */
public static final int PROFILE_OPP = 2;
/** @hide */
public static final int PROFILE_HID = 3;
/** @hide */
public static final int PROFILE_PANU = 4;
/** @hide */
public static final int PROFILE_NAP = 5;
BluetoothClass myClass=device.getBluetoothClass();
int val=myClass.getDeviceClass();
Log.e("found","class "+val);
Log.e("found","class "+(val|bitmask));
Log.e("found","PROFILE_HEADSET:"+doesclassMatch(PROFILE_HEADSET,myClass));
Log.e("found","PROFILE_A2DP:"+doesclassMatch(PROFILE_A2DP,myClass));
Log.e("found","PROFILE_OPP:"+doesclassMatch(PROFILE_OPP,myClass));
Log.e("found","PROFILE_HID:"+doesclassMatch(PROFILE_HID,myClass));
Log.e("found","PROFILE_PANU:"+doesclassMatch(PROFILE_PANU,myClass));
Log.e("found","PROFILE_NAP:"+doesclassMatch(PROFILE_NAP,myClass));
private boolean doesclassMatch(int profile,BluetoothClass myClass){
Method m=null;
try {
m=BluetoothClass.class.getMethod("doesClassMatch", new Class[]{int.class});
m.setAccessible(true);
return (Boolean) m.invoke(myClass, profile);
} catch (NoSuchMethodException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return false;
}
它将针对设备包含的特定类型或服务返回 true。
但根据 BluetoothClass 规范:
BluetoothClass is useful as a hint to roughly describe a device
* (for example to show an icon in the UI), but does not reliably describe which
* Bluetooth profiles or services are actually supported by a device. Accurate
* service discovery is done through SDP requests, which are automatically
* performed when creating an RFCOMM socket with
* BluetoothDevice#createRfcommSocketToServiceRecord} and
* BluetoothAdapter#listenUsingRfcommWithServiceRecord
