David Smart / Mbed 2 deprecated PUB_WiflyInterface_Demo

This is a demo for the WiflyInterface Library.

Dependencies:   WiflyInterface mbed

Wifly Firmware Update

Part of the demo will use the software update API to install 1 of 2 versions of the Wifly firmware, from the Microchip web site. You can see in the demo below the commands to install each of the 2 versions.

WiflyInterface - Broadcast packet

Part of the demo will send a broadcast packet to the network.
