I've got this code on a button, when I press it I get the Error:
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]

I am posting because it was working fine yesterday but seems not to be working today.
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();
}
}
}
});
According to my research this is because the bluetooth port being used is being accessed by more than one instance. But I don't see how this happens in this code.
