Generally the XBee modules need to be in API mode 1 for the Arduino libraries to work. You also need to be using the Digi Mesh firmware versions.

thanks for your replying,  
I have made code like this:

1. RECEIVER

```auto
#include <SoftwareSerial.h>
SoftwareSerial xbee(2,3);

String perintah_string;
String perintah;

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

void loop() {
    while(xbee.available()>0){
    char perintah_char = xbee.read();    
    perintah_string += perintah_char;
    perintah_string.trim();

    if(perintah_string.length()>0){      
      
      perintah = perintah_string;
      Serial.println(perintah);
      Serial.println(perintah_string);

      perintah = "";
      perintah_string = "";
    }
   }
}

```

1. TRANSMITTER

```auto
#include<SoftwareSerial.h>
SoftwareSerial xbee(2,3);

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

void loop()
{
  xbee.write("HELLO");
  Serial.println("HELLO");
  delay(1000);
}

```

And the wiring is like this for both xbee’s:

 ![xbee wire](https://us1.discourse-cdn.com/flex016/uploads/digi/original/1X/b10df92274b09f203362d53b7c277ba0ed8e9dbb.png)  
Actually i use xbee shield for this, so i make wiring like this on xbee shield:  
RX ==\> 2(ARDUINO)  
TX ==\> 3(ARDUINO)  
GND ==\> GND (ARDUINO)  
5V ==\> 5V(ARDUINO)  
and I have also tried to reverse the rx and tx pins, like RX ==\> 3 and TX ==\> 2, but no results.  
so how should i solve it?

And I have also made the configuration as follows:

If I may suggest, remove the XBee hardware from the Arduino. Then run jumper wires from the Tx of board 1 to Rx of board 2. Then do the same the other direction. Just get your code to send data from one to the other using these ports.
