Question

知道可能导致问题的原因是什么？我执行connect()函数，不再执行任何代码。

CODE：

 void openBT() throws IOException
{
    UUID uuid = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"); //Standard SerialPortService ID
    mmSocket = mmDevice.createRfcommSocketToServiceRecord(uuid);
    mmSocket.connect();
    mmOutputStream = mmSocket.getOutputStream();
    mmInputStream = mmSocket.getInputStream();

    beginListenForData();

    myLabel.setText("Bluetooth Opened");
}

logcat的：

有什么想法吗？

Answer 1

我没有正确的UUID，我通过获取正确的UUID然后在代码中替换它来解决它。

如何获取UUID：

ParcelUuid[] list = mmDevice.getUuids();

我从来没有离开过BluetoothSocket.connect（）
