Xbee+arduino COM Port problem

Development Boards Arduino
1

Hi i’m trying to get my 2 arduinos with xbee shields to communicate, but im quite stuck.

First some info:

The hardware i use is:

2x [Arduino UNO (UNO is based om ATmega328)

2x [ArduinoXBee shield PRO v1.1

2x Computers running 32-bit windows (1 XP and 1 Vista)

I try to connect using USB (COM - Ports)

I downloaded the X-CTU and installed it (Ofc ive installed Arduino IDE and drivers).

My X-CTU version is 5.1.4.1

Now to the problem, i followed a tutorial on how to communicate with xbee and arduino ([Xbee+Arduino example tutorial)

And i followed the steps but when i try to “Write” in “[X-CTU” I get a error that it lost communication with the modem.

Getting modem type… OK

Programming modem… Lost communication with modem

Write Parameters… Failed
