xbee AT command mode problem

[elmediel]

Hi All,

i've managed to program my xbee using xctu... but whenever i try to program it in serial communication, it does not reply.

when i command "+++" it replies "OK"
but when i command "ATBD" or any other command, it does not reply..

i don't understand

Have you tried xctu software supplied by the company?

yeah... i've tried that. in the modem configuration i can even update its firmware. but im really wondering why i cant do it the AT way...
