我正在制作类似于彩虹应用程序的应用程序。此应用程序将被安装在具有要发送到其他device.The应用程序的所有接触装置将要被安装的仅在一个device.I是能够通过此片的代码

连接到所述远程设备// BluetoothConnector(Complete Code)

Class> clazz = tmp.getRemoteDevice().getClass();

Class>[] paramTypes = new Class>[] {Integer.TYPE};

Method m = clazz.getMethod("createRfcommSocket", paramTypes);

Object[] params = new Object[] {Integer.valueOf(1)};

fallbackSocket = (BluetoothSocket) m.invoke(tmp.getRemoteDevice(), params);

配对请求并连接完成后，我试图通过的OutputStream通过这一段代码将数据发送到其它设备。

public void write(byte[] buffer) {

try {

Log.i(TAG, "write");

mmOutStream.write(buffer);

} catch (IOException e) {

Log.e(TAG, "Exception during write", e);

}

，但我不能够尽快发送数据mmOutStream.write(缓冲);被称为它提供了以下错误

请告诉我在上面的代码中我做错了什么。 是否可以通过蓝牙传输文件而无需实现服务器端代码？

您的BlootothDevice是否支持身份验证？源文件中的文档表明，您只能使用'createRfcommSocket'和远程设备，它支持认证。在这种情况下，它说你应该使用'createInsecureRfcommSocket'。 –
