Problem in receiving the rf packets of Xbee in API mode

Hi,
I am using Xbee pro series1 with Arduino UNO for communication. I am using the broadcast mode in API mode and Arduino Xbee library. The transmission from Co-ordinator is taking place but the packets are not being received . Can anyone tell what is error in the receiver code?

This is my code:

#include <XBee.h>


XBee xbee = XBee();
XBeeResponse response = XBeeResponse();
Rx64Response rx64 = Rx64Response();

void setup() {
  Serial.begin(9600);
   xbee.setSerial(Serial);
 

}

void loop() {
  String sample;
  xbee.readPacket(); 
    if (xbee.getResponse().isAvailable()) {
      Serial.println("packet available");
      Serial.println(xbee.getResponse().getApiId());
      if (xbee.getResponse().getApiId() == RX_64_RESPONSE) {
        xbee.getResponse().getRx64Response(rx64);
        for (int i = 0; i < rx64.getDataLength(); i++) {
          sample += (char)rx64.getData(i);
        }
        Serial.println(sample);
      }
    }else if (xbee.getResponse().isError()) {
      Serial.println("Error reading packet.  Error code: ");  
      Serial.println(xbee.getResponse().getErrorCode());
  } 
  
  delay(100);
  
  }

Thank you for your time,
Lucy
