Wino board Documentation

Description:
PLEASE ONLY USE THIS CODE IF YOU HAVE THE MODULE CONNECTED TO YOUR NETWORK.
This example shows how to communicate by a TCP-Server socket (module on server side).
To connect to the Server please use a TCP Client (like Putty) and connect to IP: 192.168.0.99 PORT:7777
You are now able to control the LED on the Wino board by the commands "led on" or "led off"
Command:

int LED_PIN = 2;

//TCP Server configuration
String port = "7777";
String clientIp = "192.168.0.99"; //This uses static IP

int listening = 0;
String answer = "";
bool wifi = false;

void setupWifi(void)
{
  //test if the module is ready
  while (!Serial.find("ready\r\n")) {}

  Serial.println("AT+CWMODE=3");
  while (!Serial.find("OK\r\n")) {}
  delay(100);

  Serial.println("AT+CWDHCP=1,1");
  while (!Serial.find("OK\r\n")) {}

  //set AP IP-adress
  Serial.println("AT+CIPAP=\"192.168.4.1\"");
  while (!Serial.find("OK\r\n")) {}

  //check for ip address
  while (!Serial.find("WIFI GOT IP")) {
  };

  //set static IP-address  
  Serial.println("AT+CIPSTA=\""+ clientIp +"\"");
  delay(100);  
  while (!Serial.find("OK\r\n")) {}

  //change to stationary mode and close AP
  Serial.println("AT+CWMODE=1");
