xbee api mode help!!

i have 2 xbees 1 configured coordinator api , configured router api.

i have attached 2 xbees 2 arduinos , test communication between them have simple code

code in arduino hooked coordinator xbee

description: check button press. upon press send zigbee transmit request frame.


int button1 = 3;


void setup(){

pinmode(button1, input);

serial.begin(9600);
 
}

void loop(){
 
 
if (digitalread(button1) == high){

senddata();

 
}


}



void senddata(){
 
 
  serial.write(0x7e);
 
  serial.write(0x00);
  serial.write(0x16);
 
  serial.write(0x10);
 
  serial.write(0x01);
 
 
  serial.write(0x00);
  serial.write(0x13);
  serial.write(0xa2);
  serial.write(0x00);
  serial.write(0x40);
  serial.write(0x8c);
  serial.write(0xc6);
  serial.write(0xd4);
 
 
  serial.write(0x20);
  serial.write(0x01);
 
 
  serial.write(0x00);
 
 
  serial.write(0x00);
 

//data start 
  serial.write(0x54);
  serial.write(0x78);
  serial.write(0x44);
  serial.write(0x61);
  serial.write(0x74);
  serial.write(0x61);
  serial.write(0x30);
  serial.write(0x41);
 
  serial.write(0x13);
 
 
   
 
  delay(10);
 
 
 
 
}


next code arduino hooked router xbee.

description: scans "0x54" byte , if there lights led. can see coordinator sends byte 0x54 along other bytes.


int bell = 5;

void setup(){

  pinmode(bell, output);

  serial.begin(9600);


}


void loop(){



  if(serial.available() >= 25){


    if(serial.read() == 0x7e){


      for(int i=0;i<24;i++){

        if(serial.read() == 0x54)
        {

          digitalwrite(bell, high);

        }

      }




    }


  }


}


i add when turn on serial monitor when press button serial monitor displays correctly data passed tx lights up. assumption problem in router not getting data rather coordinator not sending data. have been trying hunt problem couple of hours no success. highly appreciated!

maybe need use rubber bands, rather duct tape.

if connecting xbees arduinos in reasonable way, describe is. specifically, how xbee gets data from/sends data to, arduino , lights device has.

the sender sends 26 bytes. receiver waits 25 bytes , reads 25. why? after first packet, you're out of sync.
