I'm trying to send a message from my pc to the board, but the problem is I keep losing connection before I decide to send a message.

This is code from which I'm sending the message. I create a socket, connect to the board, and then wait for inputs from the Scanner object. When I get some input I send a message to the board.

CLIENT

    Socket socket = new Socket();

    socket.connect(new InetSocketAddress("192.168.4.1",3000));

    Scanner in = new Scanner(System.in);

    String message = DataProtocol.sendMessageFormat("KLASA","METHOD","FILIP CACIC");

    String message1 = DataProtocol.sendMessageFormat("KLASA","METHOD","FILIP CACIC");

    message = message1 + message;

    OutputStream outputStream = socket.getOutputStream();



    String line;

    while(!(line = in.nextLine()).equals("EXIT")){

        outputStream.write(message.getBytes());

        outputStream.flush();

    }

This is code that is recv.message.

SERVER

void CommunicationProcessor::readFromStream(WiFiClient* wifiClient){

CLIENT_ACTIVE = true;



while(CLIENT_ACTIVE){

    Serial.println(wifiClient->connected()); -> returns 1

    int bytesRead = wifiClient->readBytes(buffer,1024); -> returns 0

    Serial.println(wifiClient->connected()); -> returns 0

    dataManager.appendData(bufferReader.getDataReaded(buffer,bytesRead));



    if (checkIfEndLine(bytesRead)){

        handleDataRecv();

        dataManager.clearBuffer();

    }

}

Serial.println("CLIENT QUIT");

}

Before method readBytes, I call method connected() and it returns 1. So everything is fine.
Method readBytes returns 0, because I did not yet send any message.
After that, I call connected() one more time and this time it returns 0.

Now if I remove this Scanner object and loop from code and send a message immediately, a server will recv. message.

    Socket socket = new Socket();

    socket.connect(new InetSocketAddress("192.168.4.1",3000));

    Scanner in = new Scanner(System.in);

    String message = DataProtocol.sendMessageFormat("KLASA","METHOD","FILIP CACIC");

    String message1 = DataProtocol.sendMessageFormat("KLASA","METHOD","FILIP CACIC");

    message = message1 + message;

    OutputStream outputStream = socket.getOutputStream();

    outputStream.write(message.getBytes());

    outputStream.close();

My questions are why is connection closed after I call method readBytes?

EDIT

I just tested with this code and connection still get lost.
Line "Client alive" only gets printed one time.

SERVER

 void loop(){

   delay(1000);

   if (client){

     Serial.println("Client alive");

     Serial.println(client.connected());

   }else{

     client = server.available();

     if (client){

       Serial.println(client.connected());

   }

}
}

EDIT 2

I found the problem. I was using board as WIFI-ACCESS POINT, but when I connected board to my router and my pc, everything works fine.
So now my questions is why am I losing connection when board is configured as ACCESS-POINT?

EDIT 3

I found what was causing the problem. I had problem with connecting to wifi access point so i called method WIFI.persistent(false) and that was causing Broken Pipe exception (stream closed) in java.
