    I have given Vcc supply to one of the ADC pin and trransmitting from ATMega32 with the serial pins through MAX232 and then given to PC it is good.

     

    Zigbee module kit itself is having MAX232 so we did not connect external MAX232 and ttransmitted data from microcontroller transmissin pins to Zigbee and trying to collect information with the help of another Zigbee which is connected to laptop/PC.

     

    To be more clear we have transmitted character ‘S’ with the help of normal transmission(microcontroller-MAX232-PC) it is receiving ‘S’

    but it is receiving ‘$’ when tranmsission(Microcontroller-Zigbee-Zigbee-Pc)

    is that capital letter ‘S’ or small letter ‘s’…

    i assume it was capital one ‘S’ is 0x53 in ascii and you receiving ‘$’ which is 0x24 in ascii

    can you send some more results….

    so that i will try to figure out where exactly you went wrong…

    just ‘AND’ the recieved o/p with 01111111,i.e, 0x7f.

     worked for me

    Thanks a lot for your support. I solved this long back. I used external MAX232 even though zigbee contains inbuilt MAX232 and finally problem was solved.

    hai,

    i am a beginer to zigbee mosule.i am using x-bee pro module.i connected  a zigbee module to computer through rs232.similarly i connected another zigbee module to a different computer through rs232.i want the data typed in one computers hyperterminal to appear in another computers hyperterminal.ahould i send any commands initially to establish communication (via computers hyperterminal to zigbee module).if so what did you send.please do reply.waiting for your reply.thanks in advance.
