serial Port programming
 

Hello there,

I'm trying to emulate a Bluetooth connection via coding the serial port. COM6 on my machine is an outgoing connection over bluetooth... So I'm mocked up the following code:

package btserver1;



import gnu.io.CommDriver;

import gnu.io.CommPort;

import gnu.io.CommPortIdentifier;

import gnu.io.SerialPort;

import java.io.*;



public class Main {

    static String dataFile =null;

    /** Creates a new instance of Main */

    public Main() {

    }

    

    /**

     * @param args the command line arguments

     */

    public static void main(String[] args) {

        try {

            CommPortIdentifier pid=CommPortIdentifier.getPortIdentifier("COM4");

            SerialPort sPort=(SerialPort) pid.open("Serial Comm Testing",100);

 

            sPort.disableReceiveFraming();

            sPort.disableReceiveThreshold();

            

            sPort.setSerialPortParams(115200 , SerialPort.DATABITS_8, SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

            

            sPort.setFlowControlMode(SerialPort.FLOWCONTROL_NONE);

            

            //sPort.enableReceiveTimeout(1000);

            

            InputStream is= sPort.getInputStream();

            OutputStream os= sPort.getOutputStream();

            

            String str="11A41";

            int i =13; //char(13) is used for carriage return

            char extChar=(char) i;

            str=str + extChar;

            byte[] outByte=str.getBytes();

            

            os.write(outByte);

            

            sPort.close();

            

            

        } catch (Exception ex){ex.printStackTrace();}

    }

}

however the phone notices the connection and establishes it, but only for a second or 2... it doesn't get as far as sending the data.... Can anyone point me in a direction as to whats wrong and why?
