我在一个按钮上有这个代码，当我按下它时，我得到了错误：
Error: Exception connecting to NXT.
Caused by lejos.pc.comm.NXTCommException: Open of NXT failed.
at lejos.pc.comm.NXTCommBluecove.open(NXTCommBluecove.java:136)
Caused by javax.bluetooth.BluetoothConnectionException: Failed to connect; [10048]

我发帖是因为它昨天工作正常，但今天似乎没有工作。
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();
}
}
}
});
根据我的研究，这是因为正在使用的蓝牙端口被多个实例访问。但我看不出这段代码是如何发生的。
