Im using a RN VX 171 module with wireless shield, but also have an xbee shield from sparkfun.
I thought ID start with this simple wifi scanning example to get thing going.... Ultimately I want to just read an analogue sensor wirelessly and post the reading to cosm through our wifi network.
You can see the #include <wifi.h> below
/*
This example prints the Wifi shield's MAC address, and
scans for available Wifi networks using the Wifi shield.
Every ten seconds, it scans again. It doesn't actually
connect to any network, so no encryption scheme is specified.
