#include<WiFi.h>

// Enter your WiFi SSID and password

charssid[] ="iPhone";// your network SSID (name)

charpass[] ="8888888888";// your network password (use for WPA, or use as key for WEP)

intkeyIndex =0;// your network key Index number (needed only for WEP)

intstatus = WL_IDLE_STATUS;

// if you don't want to use DNS (and reduce your sketch size)

// use the numeric IP instead of the name for the server:

//IPAddress server(74,125,232,128);  // numeric IP for Google (no DNS)

charserver[] ="wifitest.adafruit.com";// name address for adafruit test

charpath[]   ="/testwifi/index.html";

// Initialize the Ethernet client library

// with the IP address and port of the server

// that you want to connect to (port 80 is default for HTTP):

WiFiClient client;

voidsetup(){

//Initialize serial and wait for port to open:

Serial.begin(115200);

while(!Serial){

;// wait for serial port to connect. Needed for native USB port only

}

// attempt to connect to Wifi network:

Serial.print("Attempting to connect to SSID: ");

Serial.println(ssid);

WiFi.begin(ssid, pass);

}

// from the server, read them and print them:

Serial.write(c);

}

// if the server's disconnected, stop the client:

if(!client.connected()){

Serial.println();

Serial.println("disconnecting from server.");

client.stop();

// do nothing forevermore:

}

}

}

voidprintWifiStatus(){

// print the SSID of the network you're attached to:

Serial.print("SSID: ");

Serial.println(WiFi.SSID());

// print your board's IP address:

IPAddress ip =WiFi.localIP();

Serial.print("IP Address: ");

Serial.println(ip);

// print the received signal strength:

longrssi =WiFi.RSSI();

Serial.print("signal strength (RSSI):");

Serial.print(rssi);

Serial.println(" dBm");

}
