the UART software serial In Arduino is not a 5v communication?
i did the same thing and work fine using your library, the board still working!
Nice! Thanks! I'm writing some brief code to execute commands and retrieve/parse their results. I've noticed it works at 460k baud using hardware UART, but only 38,400 reliably using SofwareSerial. For debugging I use SoftwareSerial to Wifly, pins 0,1 for debug messages, but when the code is reliable you can easily switch 2 wires and 1 define to make it faster with hardware UART. Do you see the same results?

Why don't you post the sketch you are using. It might be a simple problem like you're still using software serial when the WiFly is actually connected to the hardware serial interface, or maybe the baud rate doesn't match the rate set in the WiFly module.

It could take hours, days, or weeks for the failure to occur.To fix the problem, add a voltage divider (two resistors) between the pin you're using for TX on the Arduino and the DIN pin on the WiFly module. A nice write up on how to do this is available here: http://www.savagecircuits.com/forums/content.php?309-Mixed-Voltage-Systems-Interfacing-5V-and-3-3V-Devices.
The official arduino wireless proto shield with sd slot has a switch so you can talk directly to the RN-XV via usb... Might be a good idea to include it.http://arduino.cc/en/Main/ArduinoWirelessShield
im really glad someone took the time to write a library for this. i live in the netherlands, and i just wanted to be sure thatthis module combined with this breakout works in combination with the Wifly HQ library. can anyone confirm? I want to use Arduino as a websocketserver using this!
I've noticed that when sending large amounts of data it takes twice as long as you might expect. You have to send a buffer serially to the module, then wait for it to send it to the remote host on the internet. You cannot do both at once, so it takes more than twice as long. At 460k baud you might only get 5-10K bytes / sec. It doesn't seem to matter what is the data rate of Wifi. It seems like it needs a reply from the FTP host before you can send the next buffer via Serial. Do your results match mine when testing?
