doubt on xbee - prolem with interfacing hyper terminal

xbee india

Hi to all,

I am using xbee RF transceiver on rcm4000 to communicate with PIC16f877a. when i doin this i can transmit and receive the data but what actually i transmit. some special characters only i am receiving. i am setting 9600 baudrate in hyperterinal and the same i am using in RCM4000 program. but the data is unpredictable. why its so?

if you want any otherdetails from me to clear this problem pls ask me...................:?:

putchar xbee

It's always very helpful to see your source code. We can't guess what are doing incorrectly.

Re: doubt on xbee

thanks for your reply. here i have uploaded my code.



*******************************************************************/
#class auto

#define COUTBUFSIZE 31
#define CINBUFSIZE 15
const long baud_rate = 9600L;

main()
{
auto char send_buffer[128];
auto int received, i;
serCopen(baud_rate);
printf("Starting...\n");
strcpy(send_buffer,"A");
while (1)
{
costate
{

for(i = 0; i < 8;i++) //here i dont know why i am using this 'for' loop
{
waitfordone
{
cof_serCputs(send_buffer);// here i am writting my data to serial
} //buffer
}
}
costate
{
//receive characters in a leisurely fashion
waitfordone
{
received = cof_serCgetc();//here i am geeting data from
} //PIC16f877a
putchar(received); //just printing wat i've received
}
}
}

when i run this program i am receiving _ this only. if i transmit any other charactr i am receiving some other different special charactr , on the Hyperterminal of the system which is conneced with my PIC. i dont know why its happening. i am trying to explain my all doubts. pls adjust if i have any wrong.

what should i do more than this

Re: doubt on xbee

i just wanna know were the xbee transceivers are available in india. 2.4ghz 1mw chip antenna xbee transceivers. thank you.
