SolderSplash / Mbed 2 deprecated WifiDipCortex-UDPDemo

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

Fork of WifiDipCortex-UDPDemo by 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
