Test

  1. First you should Connect wifi module with PC via  USB To TTL Pl2303 module make sure you choose 3.3V on the USB To TTL board.  
  2. Start WiFi software to find the device. Input all the information needed to configure the wifi module.

       3. If successful, you can get the following result: 

     4. Enter the SSID, Encry Mode, Key Type and Key Parameters,Those parameters much match your wireless router.

       Also, you have to enter your the NetType parameter. IF your wireless router supports DHCP Usually most of routers support it. you can choose " Automatic IP" . Or else you have to enter IP and Gateway Parameters

      Don't select Auto Workmode

     Click Modify then Rest Now to reset the module.

     Close the software and restart it again  Search and connect as descripted above. Choose the FuncTest in the top menu, and click connect

    5. Connect this module with Arduino by using Wifi Shield Arduino Compatible With Microchip

After the configuration on wifi module, upload the following code to Arduino:

void setup()
{
Serial.begin(115200);
}
void loop()
{
boolean currentLineIsBlank = true;
while(1){ 
if (Serial.available()) {
char c = Serial.read();
// if you've gotten to the end of the line (received a newline
// character) and the line is blank, the http request has ended,
// so you can send a reply
if (c == 'n' && currentLineIsBlank) {
// send the webpage
Serial.println("HTTP/1.1 200 OKrnContent-Type: text/htmlrnrn<center><h1>Hello World!! I am WiFi WebServer!!!</h1></center>");
break;

}
if (c == 'n') {
// you're starting a new line
currentLineIsBlank = true;

else if (c != 'r') {
// you've gotten a character on the current line
currentLineIsBlank = false;
}
}
}
}
