I am facing a problem related to xbee and requires your help. Actually I am making a project "Home automation using xbee".
In this project I want to use pir sensor,fire sensor and receive its output through xbee at controller(pic 16877A) side to the Xbee at user end and controlling the ac devices accordingly from computer. But my main problem is that I am not able to configure my xbee for both receiving and transmitting simultaneously. One of my xbee is acting like receiver and other is acting like transmitter at a time. Since I require my xbee to obtain signals from sensors at controller side to the pc and send commands from my pc to the controller and control devices and therefore seeking your help to configure xbee for transmission and reception simultaneously.
Do I need to use 4 xbee i.e 2 at controller side for transmitting and receiving respectively and two at pc end for receiving and transmitting or it is possible using 2 xbee only i.e 1 at controller side and other one at pc side for transmitting and receiving respectively, please tell me the required configuration.
My xbee model is:- XB24-B
Thanks in advance.
