XBee Communication Failure on BL4S100

Rabbit
1

I am trying to use the Rabbit board as a web to ZigBee interface. I have the following code running on the BL4S100 board:





    #class auto

//
#define XBEE_ROLE		NODE_TYPE_ROUTER
#define DEFAULT_PANID 0x1234


#define NODEID_STR "My Router"


#define	STDIO_DEBUG_SERIAL	SADR
#define	STDIO_DEBUG_BAUD		9600
#define	STDIO_DEBUG_ADDCR

#define XBEE_DEFAULT_CHANNELS 0xfff

#define CLUSTER_ID 1
char * proto;


#memmap xmem
//Includes:
#use "xbee_api.lib"


/***********************************
 * Configuration                   *
 * -------------                   *
 * All fields in this section must *
 * be altered to match your local  *
 * network settings.               */



int incomingString(){
 return 0;
}

RabbitClusterIDList_t const StringInCluster = {
   { CLUSTER_ID },
   { incomingString }
};


ENDPOINT_TABLE_BEGIN
ENDPOINT_TABLE_ENTRY(1, 0, 1, 1, 0, 1, 0, &StringInCluster, NULL)
ENDPOINT_TABLE_END
int join_start;
int initres;

//char * proto;
int main(){
   brdInit();

   printf("Protocal is: %s", xbee_protocol());
join_start = 0;
while ( (initres = xbee_init()) == -EBUSY){
   if (! join_start){
      join_start = SEC_TIMER;
      printf("Waiting for sleeping XBee to wake before continuing.");
   }
   if (join_start != SEC_TIMER){
      join_start = SEC_TIMER;
      printf( ".");
   }
}
printf( "
");
if (initres){
   printf("xbee_init failed");
   exit(1);
}


printf("Waiting to join network...
");
join_start = MS_TIMER;
while (ZB_JOINING_NETWORK()) {
   // If unable to join a network, timeout after arbitrary time
   if (MS_TIMER - join_start > XBEE_JOIN_TIMEOUT) {
      printf("
*** Error ***
");
      printf("Timed out while trying to join a network.
");
      exit(-ETIME);
   }
}

printf("Done (%s network)
", xbee_protocol());




}

I have a ZigBee network with a PAN ID of 0x1234. (I have one Coordinator)

No matter what I do, I cannot get the Rabbit to connect to it. It keeps timing out.

I tried connecting the XBee via serial port to X-CTU. It does not show up. I then set the Baud rate to 11520 with Hardware flow control and enabled the API. It recognizes a serial modem but does not let me read any values, or update the firmware.

Next, I tried putting in an XBee module that I know works into the Rabbit board. The code now fails in the initialization stage. I suspect it is trying to communicate at the wrong Baud rate.

Should I try to put a different firmware version on the other XBee modules on my network that is the same as the Rabbit provided XBee? (How??)

Is there a way to change the Baud rate Dynamic C compiles the board to use when communicating to the XBee?

Any help would be greatly appreciated.

Did you ever get a reply on this?
