Carl - SolderSplash Labs / Mbed 2 deprecated WiFiDip-KitchenSink

WiFi DipCortex / CC3000 Demo - Contains a menu driven set of tests to initalise and control the CC3000 radio. Also allowing you to test various TCP and UDP connections.

Dependencies:   NTPClient WebSocketClient cc3000_hostdriver_mbedsocket mbed HTTPClient

http://www.soldersplash.co.uk/products/wifi-dipcortex/

Please Note, this example uses the serial port so you will need an external RS232 TTL to USB adapter.
