Need to change XBee destination address

SEL

I am new to using GCC. Perhaps someone would be kind enough to help me.

I am using an activity board with a series 1 xbee. The other is a propdemo board using sip xbee adapter, also series 1.
I can not change MY or DL address. Out of the box the two are communication; both are set to address 0. I need to change the DL address.

I have gone through the Learning GCC series of tutorials.

Any Help here would be great.
Here is my c code:

#include "simpletools.h" // Include simple tools
#include "fdserial.h" // Full-Duplex Serial

fdserial *xbee;

static void xbeeSetup();

int myAddr = 0x0;
int dlAddr = 0x3;

int main() // Main function
{
xbee = fdserial_open(1,0,0,9600);
pause(1000);

xbeeSetup(myAddr, dlAddr);

fdserial_txChar(xbee,'!');
fdserial_txChar(xbee,'1');
writeDec(xbee,13);

pause(5000);

fdserial_txChar(xbee,'!');
fdserial_txChar(xbee,'2');
writeDec(xbee,13);

pause(5000);

fdserial_txChar(xbee,'!');
fdserial_txChar(xbee,'3');
writeDec(xbee,13);

pause(100);
}

static void xbeeSetup(int myAddr, int dlAddr)
{
pause(3000);
fdserial_txChar(xbee,"+++");
pause(2000);
fdserial_rxFlush;
fdserial_txChar(xbee,"ATGT 3, CN");
writeDec(xbee,13);
pause(500);
fdserial_rxFlush;

pause(100);
fdserial_txChar(xbee,"+++");
pause(100);
fdserial_txChar(xbee,"ATMY\r");
writeHexDigits(xbee,myAddr,4);
writeDec(xbee,13);
fdserial_txChar(xbee,"ATCN\r");
writeDec(xbee,13);

pause(100);
fdserial_txChar(xbee,"+++");
pause(100);
fdserial_rxFlush;
fdserial_txChar(xbee,"ATDL\r");
writeHexDigits(xbee,dlAddr,4);
writeDec(xbee,13);
fdserial_txChar(xbee,"ATCN\r");
writeDec(xbee,13);
pause(100);

}

I don't know GCC syntax, but I see a couple of places where you've used single quote ' where it might need ".

I think the following is incorrect (and the same for setting MY):

[SIZE=1][FONT=courier new]fdserial_txChar(xbee,"ATDL\r");
  writeHexDigits(xbee,dlAddr,4);
  writeDec(xbee,13);
  fdserial_txChar(xbee,"ATCN\r");
  writeDec(xbee,13);[/FONT][/SIZE]

That will actually send the two ascii chars \r that shouldn't be there. To set DL=$abcd, the modem has to receive the string just as if you had typed it in on a terminal.
ATDL abcd <CR>
Don't send the 13=<CR> as a decimal value. It has to be the single byte of value decimal 13.

In Spin the following would set MY=1, DL=2, writes it to the XBee eeprom so that it will be restored after power cycling.
fds.str(string("AT MY1 DL2 WR CN",13))
Separating individual AT commands with <CR> is optional, or with repeated +++.

First: Thank you for taking the time to try and help!

I tried all your suggestions, but could not change address.

I need a code example written in C. I have googled for such an example and could find nothing. All wanted to us X-CTU. I have changed the address using that application. That is a hard wire solution. I need a software solution.

Once again any help would be so appreciated!

What exactly did you try?

SEL

I think I have found a method, but I am not very happy with the solution because I want to pass parameters to a function.

Here is the code:

static void xbeeSetup(myAddr, dlAddr)
{
char thisByte = 0;

dprint(xbee,"+++");

while(thisByte != 'K')
{
thisByte = fdserial_rxCheck(xbee);
if(thisByte != -1 )
{
thisByte = fdserial_rxChar(xbee);
}
}

dprint(xbee,"ATDL0\r");
dprint(xbee,"ATMY0\r");
dprint(xbee,"ATCN\r");
}

I have to work out: how to use itoa(xbee, myAddr, ?) or something like it. It is hard not knowing that much about C, but I am learning.
The third parameter of itoa I have no clue as what I need there.

char myA = itoa(xbee,myAddr, ?) ;

Your question is more related to GCC than it is to the XBee. At least, that is where I am lost. Maybe try the GCC subforum; pose your question there, with the code you have already tried with incomplete success. There is currently a thread there on using the serial ports in GCC.

Tracy, thank you for your time!!!!

Well I finally have what I want. Here is the CODE:

#include "simpletools.h" // Include simple tools
#include "fdserial.h" // Full-Duplex Serial

fdserial *xbee;

static void xbeeSetup();
static void flashLeds(void);

char myAddr = 0x1;
char dlAddr = 0x0;

int main() // Main function
{
xbee = fdserial_open(1,0,0,9600);

int dataIn;

xbeeSetup(myAddr, dlAddr);

while(1)
{
dataIn = 0;
dataIn = fdserial_rxChar(xbee);
if (dataIn == '!')
{
dataIn = fdserial_rxChar(xbee);
switch(dataIn)
{
case '1':
high(23);
break;

case '2':
low(23);
break;

case '3':
flashLeds();
break;
}
}
}
}

static void xbeeSetup(int myAddr, int dlAddr)
{
char thisByte = 0;
char xx[10];

char my[10] = "ATMY";
char dl[10] = "ATDL";

itoa(myAddr,xx,10);
strcat(my,xx);
itoa(dlAddr,xx,10);
strcat(dl,xx);
strcat(dl,"\r");
strcat(my,"\r");

dprint(xbee,"+++");

while(thisByte != 'K')
{
thisByte = fdserial_rxCheck(xbee);
if(thisByte != -1 )
{
thisByte = fdserial_rxChar(xbee);
}
}

dprint(xbee,my);
dprint(xbee,dl);

dprint(xbee,"ATCN\r");
}

static void flashLeds(void)
{
for (int i=0; i<4; i++)
{
high(16);
pause(500);
low(16);
pause(500);
high(23);
pause(500);
low(23);
pause(500);
}
low(16); low(23);
}
