Async Wifi Sheild v2.0   Socket code  Help

Hello, I can get the code to compile and upload but cannot see why I cannot read a string over the socket created and parse and act on that string.

This is a slightly modified example.

char mybuff[20], sendbuff;
String x; 
void setup()
{
      WiFi.init();
        Serial.begin(9600);
        pinMode(7,OUTPUT);
        digitalWrite(7,LOW);
}

void loop()
{
      WiFi.run();
        Serial.print(mybuff);
        x = mybuff;
        Serial.print(x);
        //delay(100);
        if (x == "on")
        {
        digitalWrite(7, HIGH);
        }
        if (x == "off")
        {
        digitalWrite(7, LOW);
       }
}

Socketapp.c remains unchanged.

I am using python to send these commands:

>>> import socket

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(("192.168.1.2", 9000))

>>> sock.send('on')

Can anyone see why the LED does nothing upon the command being issued?

Never mind I figured it out that the python terminal wasnt sending '/n' across properly, instead i changed the socketapp.c read to value to '=' and it works fine.
