The Roving Networks RN-XV WiFly module is an easy way to add WiFi network support to your Arduino projects. It has the same footprint as the XBee module and shares the same Serial I/O lines.
The WiFlyHQ library provides a high level interface to the WiFly module and has examples for an HTTP server, HTTP client, TCP server and client, UDP client, WebSocket client, and two router bandwidth monitors using SOAP and SNMP.
Any way to get the "set sys launch_string <string> function added for the version 4 firmware?
