Small demo to purely test UDP, depends on the module already being configured to auto connect to an access point
Dependencies: USBDevice cc3000_hostdriver_mbedsocket mbed

WifiDipCortex-UDPDemo

Carl - SolderSplash Labs
Wifi-DipCortex - Test application that shows you how to listen for UDP message on one port while sending messages on another
- Listens on UDP_LISTEN_PORT, upon data being recvied it can be found in UDP_RecvBuffer - Transmits UDP_TX_Buffer on UDP_TARGET_PORT to UDP_TARGET_IP
