I finally got this board to work with Arduino Mega. I'm sorry to say it takes some modifications to make it work. Basically you have to change the pins in Spi.h to match the mega and do the hack described at <http://mcukits.com/2009/04/06/arduino-ethernet-shield-mega-hack/>. Good Luck!

Where can i find an arduino sketch to kick start the development when i but them !

Any WiFly Shield equivalent for arduino or maple¿

Hi
quick question: once I connect the Wifly to the Arduino, should I get any led to turn on?
I'm wondering this because I try to connect using the code avaliable in the tutorial, and I get the message:
"Could not initialize bridge, locking up."
I have no idea what to do?
Any help?

Salut tout le monde !
Anyone have tryed UDP mode ? Who have sample ?
I have succeed to setup auto pairing mode tought broadcast, but i have don't find the way for send data in UDP mode .... :(
Thx all

After buying the board, I was disappointed to discover the RN-131G only supports one active TCP connection at any given time, unlike the Ethernet shield which supports up to 4 connections. This means the shield cannot be used to implement an Ajax-type web server, since most such web apps would need 2 connections opened to the server.

Can someone help? After I type $$$, I get this (the last line repeats over and over):
WiFly Shield Terminal Routine
Bridge initialized successfully!
Auto-Assoc roving1 chan=1 mode=NONE FAILED
CMD
Auto-Assoc roving1 chan=1 mode=NONE FAILED
Whatever I type after is only echoed back to the PC.
Any ideas?

Very important if you are just buying one of these now and are using the examples above to test it out. The new wifly operates at a faster frequency of 14745600UL. So you need to adjust the line that is:
struct SPI_UART_cfg SPI_Uart_config = {
0x50,0x00,0x03,0x10};
to:
struct SPI_UART_cfg SPI_Uart_config = {
0x60,0x00,0x03,0x10};

What voltage regulator are you using? It's not clear from the schematic. Mine powers off at about 15V (when I'm charging my 12V battery). I'm considering moving the power to the regulator from Vin to the 5V line.

I bought one of these to send twitter updates for a sensor project I'm working on. If anyone wants to they can check out my code (based on the sparkfun tutorial):

I'm having the same problem. I can get it to work fine in command mode over USB, issue commands perfectly. But not connect to either of my networks. Channels, baud, MHz all seem to match. But I can't get it to associate with a network. On one network security is 3, on the other it is 0 (open) and still nothing.
Please help!

Hey there:
I am working with this Wifi module.
I got this to work with my arduino and I am able to access the command lines via USB comport.
But I want to send data to my computer that is being generated by my arduino wireless. I know how to do it wired(USB), but not wireless.
can some one help with this?

Will I be able to connect to WiFly from Arduino via UART with 250000 baud rate?
Or it will still require SPI?

I was using the the sketch and information posted by 'El Hombre Mecatr?nico' and I was able to get my project running but it wouldn't remain stable. At times the SPI bridge would be unworkable for days (multiple resets).
I modified my program to use SparkFun's code in this tutorial and everything works perfectly. No hang-ups. No unresponse SPI bridge issues.

This is definitly the solution for everyone. I really appreciate the fact that they took the time to put this together. Just wish something like this existed two months ago when I first purchased the board.

I didn't think the Arduino library supported SPI?

You can find an arduino sketch (WiflyTerm 1.0) that gives you access to the RN-131G through the arduino's serial port.
Just open a Hyperterminal (not the arduino serial monitor) and configure the USB serial port at 9600,N,8,1 with no flow control, and type $$$ to enter the configuration console.
You can configure unconnected wifly modules and save the configuration in NV memory as the default, so the module connects automatically and this program is no longer needed. With this program you don't need to change your network SSID/encription to configure the module.
The blog entry in spanish (sorry): http://hombremecatronico.es/?p=247
Or just get the Wiflyterm 1.0 at: http://hombremecatronico.es/wordpress/wp-content/uploads/2010/01/wiflyterm.zip

I'm running the above code and getting absolutely no response using the code linked to above. Anyone?

Why is the SC16IS750 interrupt connected to Digital 7, instead of D2 or D3, which are the CPU external interrupt pins?

Check out http://hombremecatronico.es/?p=247 its in Spanglish, but has the code to get started.

We can't get this to work with the Arduino Duemilanove. More specifically we don't receive any response from the SPI chip. Is there any starter code?

any idea when this product will be back in stock ?

I'm surprised that nobody has mentioned the WiShield yet. It's an equivalent shield for $35.00 less. It also has a pretty decent following in the Arduino forums.
Check it out! http://asynclabs.com/store?page=shop.product_details&flypage=flypage.tpl&product_id=17&category_id=6

Can this be used with the Arduino Mega?

Can anyone help me understand why Arduino can't be connected to RN-131G module directly using SPI interface instead of going through a SPI-UART bridge like one on this board ?
Thanks

It is called "wishield" ? Is it the same as this one -

would love to see a tutorial on wifi bootloading the arduino...you're right there on the isp pins for the avr....

Why you use RN-131G??? RN-131! the similar but chipper.
