远程蓝牙

Question

我正在努力了解工作客户端 - 服务器蓝牙.android是客户端的地方.PC是服务器.

我找到了代码.这工作了三星galaxy 10.1(android 3.2),但不适用于三星galaxy s(android 2.3.3)和htc wildfire s(android 2.2).

MY_UUID = UUID.fromString("04c6093b-0000-1000-8000-00805f9b34fb");

Answer 1

您的设备无法进行服务发现(我认为如此).

1. 我已经阅读了许多三星设备和HTC设备的BT问题,但那些专门用于L2CAP/HID配置文件的设备.Soln:如果您使用的是L2CAP,可以使用SPP或RFCOMM

2. 如果您使用上述解决方案之一,请尝试使用标准UUID

SPP 00001101-0000-1000-8000-00805F9B34FB

RFCOMM 00000003-0000-1000-8000-00805F9B34FB

或者,您可以尝试使用反射来获得类似于以下方法的套接字连接

private static BluetoothSocket createBluetoothSocket(
        int type, int fd, boolean auth, boolean encrypt, String address, int port){
    try {
        Constructor<BluetoothSocket> constructor = BluetoothSocket.class.getDeclaredConstructor(
                int.class, int.class,boolean.class,boolean.class,String.class, int.class);
        constructor.setAccessible(true);
        BluetoothSocket clientSocket = (BluetoothSocket) 
            constructor.newInstance(type,fd,auth,encrypt,address,port);
        return clientSocket;
    }catch (Exception e) { return null; }
}
