Receiving data from GT06 GPS in Java

Question

I am developing a fleet application where I need to track my vehicle movement and store that into a MySQL db. Am using GT 06 GPS with a sim card.

I created a Java file for checking that GPS is sending the data or not. My program is connected with the GPS but the data I am receiving is not clear. How can U parse the data or is the data I am receiving is wrong?

Below is the program I am using:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class BackupServerListener {

public static void main(String[] args) {
    new ServerListener().startServer();
}

public void startServer() {
    final ExecutorService clientProcessingPool = Executors.newFixedThreadPool(03);

    Runnable serverTask = new Runnable() {
        @SuppressWarnings("resource")
        public void run() {
            try {
                ServerSocket serverSocket = new ServerSocket(9876);
                System.out.println("Waiting for clients to connect...");
                while (true) {
                    Socket clientSocket = serverSocket.accept();
                    clientProcessingPool.submit(new ClientTask(clientSocket));
                }
            } catch (IOException e) {
                System.err.println("Unable to process client request");
                e.printStackTrace();
            }
        }
    };
    Thread serverThread = new Thread(serverTask);
    serverThread.start();
}

private class ClientTask implements Runnable {
    private final Socket clientSocket;

    private ClientTask(Socket clientSocket) {
        this.clientSocket = clientSocket;
    }

    public void run() {
        System.out.println("Got a client !");
        while (true) {

        try {
            BufferedReader reader = new BufferedReader( new InputStreamReader(clientSocket.getInputStream()));
            String clientData = "";

            clientData = reader.readLine();
            String hex_value = asciiToHex(clientData);
            System.out.println("clientdata::::"+hex_value);

        } catch (IOException e) {
            e.printStackTrace();
        }
   
     }

    }
    private String asciiToHex(String clientData) {

        char[] chars = clientData.toCharArray();
        StringBuffer hex = new StringBuffer();
        for (int i = 0; i < chars.length; i++)
        {
            hex.append(Integer.toHexString((int)chars[i]));
        }
        return hex.toString();
    }

 }
}

Answer 1

I'm looking for a tool that will let me check the raw data from my device. I would like to be able to diagnose and analyze the data from the device end. Can you recommend anything? like any simulator type ?

public class BackupServerListener {

public static void main(String[] args) {
    new BackupServerListener().startServer();
}

!!!!!Instead of !!!!!!!!!!
public class BackupServerListener {

public static void main(String[] args) {
    new ServerListener().startServer();
}
