The interface=wifi parameter applies only to TCP/UDP connections. To establish a Wi-Fi® connection and use a Wi-Fi API in a BlackBerry® device application, the wireless service provider must support Wi-Fi access.

1. Import the following classes:
   • java.lang.String
   • javax.microedition.io.Connector
2. Import the javax.microedition.io.StreamConnection interface.
3. Invoke Connector.open(), specify socket as the protocol, and append the deviceside=true parameter and the interface=wifi parameter to the end of the URL string value.

   private static String URL = "socket://local_machine_IP:4444;deviceside=true;interface=wifi";
   StreamConnection conn = null;
   conn = (StreamConnection)Connector.open(URL);
