I bought a RN-XV WiFly Module - Wire Antenna recently for my next robot project. It's cute and beautiful, I fell in love with it as soon as I received it.

To play with this XBee-like little thing, a breakout board and sockets/headers are needed.
Now there comes interesting part of this. I'm going to set it up. This module has an Adhoc setup mode, which means if you don't have any adapters like a XBee Explorer, you can still work with it through wifi. This is what I'm going to do, though I actually have a XBee Explorer.
Now what you need to do is just power the module. Please be aware, this is a 3.3V device like XBee, and according to the data sheet, the UART_RX/TX are 3.3V tolerant. At the moment, no need to worry about the TX/RX part, just power it. Also, GPIO 9(Pad 8) should be set to High to enable the Adhoc mode. I used Arduino 3.3V pin as power source. Like this:

Now you should be able to see the wifi network your RN-XV broadcasts on your computer(Of course, your computer should be working with a wireless adapter). Connect to it.


Next, telnet to the module at port 2000. In Windows 7, telnet is not default installed. Just Google it to find out how to enable telnet client.

Connecting...

If you can see "*HELLO*", congratulations!! You get Connected!!

Type $$$ (without hitting return) to enter command mode.

Now it's time to RTFM, see what we can do in the command mode.
