hi everyone,

i am writing a program on ZigBee using Microsoft visual Studio 2005 C#. But currently i couldn't get the result i desired. I was able to establish PAN and scan for node, but i couldn't get my node to read temperature, sound the buzzer and ON/OFF the LEDs. So if possible, can anyone out there please help me check and recorrect my program. Thanks, your help is truely appreciated.
