I have an Arduino Mega 2560 with an IO Expansion Shield v1.2 (http://www.dfrobot.com/index.php?route=product/product&product_id=339). I plugged in an XBee Wifi module and am having trouble getting your code to work. I'm not sure if it's a matter of assigning the right pins or if there is some other issue. I'm not sure what Arduino board you're using, but I'm very confused by your pin assignments:

define XBEE_RESET 20

define XBEE_ATN 2

define XBEE_SELECT SS

define XBEE_DOUT 23

Where did you get these pin numbers from? Do you just pick any digital pins for ATN, RESET, and DOUT? Any help you could provide would be greatly appreciated.

Hi Chris,
My name is Mirko Rodić from Croatia, student of the fifth year of Wireless Communications, and I am using your code Xbee Wifi library. Please can you help me, I’m trying to initilize Xbee Wifi 24 S6, and it’s giving me erorr constantly:
No ATN assert on reset

Failed in rx_frame, invalid start byte, I get 0x0 or 0xFF instead of 0x7E

I connected proper required pins on my arduino uno, I don’t know how to solve problem, and would be very grateful if you could help me.

Best Regurds,
Mirko Rodić

Hello

I've been working with this library on an Arduino Uno, with an Xbee module attached via a Wireless SD shield. I'm having difficulty getting the code to work, and I believe it's because I don't have the correct pins for the required pinouts -- Select, Attention, Reset and Dout.

Select should be Pin 10 on the Uno, according to the Arduino's page for the Wireless SD shield. Dout would seem to correspond to MOSI, which is pin 12. I do not know why your code doesn't need MISO or CLK, as those are part of SPI.

I tried running a small wire from the Arduino pin 5 to the Xbee pin 5, and specifying that as reset in your code. And I ran another from pin 6 to Xbee pin 13, for atn. Yet your code still states that Xbee Init Failed.
