MKRWifi1010 - Servidor Web

[aprentik]

Buenos días. Debo hacer un pequeño servidir Web con un MKRwifi1010. Debo preguntar por un nombre y un apellido. Pasar ese nombre y apellido a dos variables. No sé cómo pasar el valor que entro en la Web a una variable y poder trabajar con esta variable. Os adjunto el código que estoy usando, que es una modificación del código ejemplo de abrir y apagar leds. Alguien sabe cómo puedo pasar la información que entro en la web a la variable "nom" y "cognom"

Al apretar el botón "OK" es cuando quisiera cargarlo

char pass[] = "";                     // your network password (use for WPA, or use as key for WEP)
int keyIndex = 0;                     // your network key Index number (needed only for WEP)

    // don't continue
    while (true);
  }

  // wait 10 seconds for connection:

  // start the web server on port 80
