Avnet / WNCInterface

The WDCInterface is is a drop-in replacement for an EthernetInterface class that allows the user to connect to the Internet with a Wistron NeWeb Corporation (WNC) M14A2A Series data module using the standard network Socket API's. This interface class is used in the AT&T Cellular IoT Starter Kit which is sold by Avnet (http://cloudconnectkits.org/product/att-cellular-iot-starter-kit).

Dependencies:   WncControllerK64F

Dependents:   WNCProximityMqtt Pubnub_ATT_IoT_SK_WNC_sync BluemixDemo BluemixQS ... more

See the WNCInterface README in the Wiki tab for detailed information on this library.
