I am starting with this xBee thing and I am very confused.
First I would if someone could share some more comprehensive reading material about this subject.
All that I found is so incomplete and sparse.

I mounted an xBee 802.15.4 in a breakout board and connect RX and TX with TX and RX from the arduino duemilanove.
I plugged the xStick 802.15.4 in the laptop, started  xCtu and configured it as coordinator.
I try Remote Configration but it detects nothing, no one node.

How could I be sure the xBee is working or is misconfigured?

I uploaded this program to arduino:
#include <NewSoftSerial.h>
// For the electronic wiring , you should :
// Connect pinRx to the Pin2 of XBee(Tx , Dout)
// Connect pinTx to the Pin3 of XBee(Rx , Din)

// Define the pins on Arduino for XBee comminication
uint8_t pinRx = 2 , pinTx = 4; // the pin on Arduino
long BaudRate = 57600 , sysTick = 0;
char GotChar;
// Initialize NewSoftSerial
NewSoftSerial mySerial( pinRx , pinTx );

void setup() 
{ // You shall see these messages in Arduino Serial Monitor
// This part is the official library , it will be used for talking to
// PC serial port
   Serial.begin(BaudRate);
   Serial.println("XBee Communication Test Start !");
   Serial.print("BaudRate:");
   Serial.println(BaudRate);
   Serial.print("NewSoftSerial Rx Pin#");
   Serial.println(pinRx,DEC);
   Serial.print("NewSoftSerial Tx Pin#");
   Serial.println(pinTx,DEC);

   // This part is the NewSoftSerial for talking to XBee
  mySerial.begin(BaudRate);
   mySerial.println("Powered by NewSoftSerial !");
}

void loop()                   
{
   sysTick++ ; // a system timer
/* //for debug
  Serial.print("Xbee Timer :");
  Serial.println(sysTick);
  mySerial.print("Xbee Timer :");
  mySerial.println(sysTick);
*/
// Monitor Rx from PC , if the data is available then read
// it to "GotChar".    Then ask XBee send the data out
// wirelessly.
  if ( Serial.available() ) {
       GotChar = Serial.read();
       mySerial.print(GotChar);
   }
// Monitor data from XBee , if the data is available then
// read it to "GotChar".    Then send it back to PC.
  if ( mySerial.available() ) {
       GotChar = mySerial.read();
       Serial.print(GotChar,BYTE);
   }
}

Which XBee? Which breakout board?

Power? Ground?

You tried to remote re-configure an XBee that you had never configured? No surprise that that didn't work.

The xBee is this exactly this, where I bought it
http://xbeestore.lojavirtualfc.com.br/sistema/listaprodutos.asp?IDLoja=16187&Y=999741064702&IDProduto=2559266&q=modulo-digi-xbee-802-15-4---antena-chip---low-power

The board is this simple one

The USB adapter is this

I connect power to the arduino 0.3v and the ground.

My hope was that I could configure it remotely with the USB adapter.
Do you mean it´s not possible? I realy need a USB or serial board?

I don't know. I can't read those links. I doubt, it though. A USB Explorer, like this one, http://www.sparkfun.com/products/8687 is probably going to be in your future, so that you can configure the XBee.

That XBee stick looks interesting, though.

According to the Geting Started Guide from Digi, is possible remote configure a xBee.
My problem is that I cant detect the remote xBee and dont how to track what is wrong.

Finally I got comunication between the XBee and XStick.
I have changed the pins from rx (0) and tx (1) to 5 and 6 respectively, just because these are free.
Changed the baudrate in XStick, softserial, com port monitor and XCTU to 9600.
The rest of the setings are default.
It works perfectly, I type ascii into the XCTU terminal and it appears into the Arduino COM port monitor and vice-versa.

By the way I still cant configure the Xbee remotely. Will try again with the correct baudrates.
Thanks everybody.
