I have done a lot of progress since yesterday , as you scroll down i have 2 post where i was struggling with getting some apps which are able to communicate with each other utilising the TCP/IP stack.
today i made the apps where in there is a client and a server that is working pretty fine as they should but the only problem IS COMMUNICATING with the Arduino, i have a ethernet arduino based itead iboard which has a W5100 chip and its working pretty smooth with pachube etc , and it is very good so at this place no problem.
i also tried the following TELNET client request on port 80 but its STILL NOT connecting to the Ethernet Arduino of mine:
/*
Telnet client
This sketch connects to a a telnet server (http://www.google.com)
using an Arduino Wiznet Ethernet shield. You'll need a telnet server
to test this with.
Processing's ChatServer example (part of the network library) works well,
running on port 10002. It can be found as part of the examples
in the Processing application, available at
http://processing.org/

#include <SPI.h>
#include <Ethernet.h>
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,1,5);
// Enter the IP address of the server you're connecting to:
IPAddress server(127,0,0,1);
// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 23 is default for telnet;
// if you're using Processing's ChatServer, use port 10002):
EthernetClient client;
void setup() {
// start the Ethernet connection:
Ethernet.begin(mac, ip);
// start the serial library:
Serial.begin(9600);
// give the Ethernet shield a second to initialize:
delay(1000);
Serial.println("connecting...");
// if you get a connection, report back via serial:
if (client.connect(server, 80)) {
Serial.println("connected");
}
else {
// if you didn't get a connection to the server:
Serial.println("connection failed");
}
}
void loop()
{
// if there are incoming bytes available
// from the server, read them and print them:
if (client.available()) {
char c = client.read();
Serial.print(c);
}
// as long as there are bytes in the serial queue,
// read them and send them out the socket if it's open:
while (Serial.available() > 0) {
char inChar = Serial.read();
if (client.connected()) {
client.print(inChar);
}
}
// if the server's disconnected, stop the client:
if (!client.connected()) {
Serial.println();
Serial.println("disconnecting.");
client.stop();
// do nothing:
while(true);
}
}
This is my c# server app running on the SAME PC ON WHICH IM WORKING (so the app works on the same PC where the arduino IDE is there and serial port opens i mean the VERY VERY SAME pc):
I have tested this server with a client same written in the c# visual studio and it works pretty good.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.Sockets;
using System.Net;
namespace Server
{
class Program
{
static TcpClient connected;
static void Main(string[] args)
{
TcpListener listener = new TcpListener(IPAddress.Any, 80);
listener.Start();
while (true)
{
connected = listener.AcceptTcpClient();
sendevent:
send();
goto receiveevent;
receiveevent:
receive();
goto sendevent;
}
}
static byte[] buffer = new byte[4096];
static void receive()
{
NetworkStream read = connected.GetStream();
int data = read.Read(buffer, 0, 4096);
Console.WriteLine("Client: "+ Encoding.ASCII.GetString(buffer, 0, data));
}
static void send()
{
byte[] data = Encoding.ASCII.GetBytes(Console.ReadLine());
NetworkStream stream = connected.GetStream();
stream.Write(data, 0, data.Length);
}
}
}
Do i have run client and server on SEPARATE systems?
