我的应用程序的一部分通过蓝牙连接到设备,通常工作正常但偶尔它不会连接,我得到以下错误

03-11 10:29:20.328: E/BluetoothComService(8059): accept() failed
03-11 10:29:20.328: E/BluetoothComService(8059): java.io.IOException: Operation Canceled

这是我得到例外的那一行

socket = mmServerSocket.accept();    

这是完整的AcceptThread

private class AcceptThread extends Thread {
    // The local server socket
    private BluetoothServerSocket mmServerSocket;
    public boolean successInit = false;

    public AcceptThread() {
        closeAllConnections();

        /*
         * if(mmServerSocket != null) { try { mmServerSocket.close(); } catch
         * (IOException e) …
