我有一個按鈕,這個代碼,當我按下它,我得到的錯誤:連接失敗[10048]
Error: Exception connecting to NXT.

我張貼,因爲它工作正常,但昨日似乎沒有被工作今天。
btnConnectBot.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if (Cnt1){
try {
conn.close();
Cnt1=!Cnt1;
txtConnState.setText("Off");
txtConnState.setForeground(Color.RED);
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
else{
conn.addLogListener(new NXTCommLogListener() {
public void logEvent(String message) {
System.out.println(message);
}
public void logEvent(Throwable throwable) {
System.err.println(throwable.getMessage());
}
});
conn.setDebug(true);
if (!conn.connectTo(txtBotName.getText(), NXTComm.LCP)) {
System.err.println("Fallo de conexión");
txtConnState.setText("Off");
txtConnState.setForeground(Color.RED);
System.exit(1);
}
Cnt1=!Cnt1;
txtConnState.setText("On");
txtConnState.setForeground(Color.GREEN);
if (chckbxLock_2.isSelected()){
btnConnectBot_2.doClick();
}
if (chckbxLock_1.isSelected()){
btnConnectBot_1.doClick();
}
}
}
});
根據我的研究,這是因爲正在使用的藍牙端口正在被多個實例訪問。但是我不明白這個代碼是如何發生的。
