xbee pro xsc s3b configuration

hello,

i have 3 xbee pro xsc module(s3b) and i want to set up one of them as coordinator which receiver, other two modules as transceiver in same network.

i'm new in rf communication. probably for this reason, i can't configure xbee's correctly using xtcu program.

i'm using new version of xctu (6.3). there are a lot of videos and blog post about xtcu, arduino and xbee but almost all of them used xbee seri 1 or 2. but i'm using series 3 and i can't configure it.

i will attach screenshot the xctu program.

is there anyone to help configure xbee using xctu? or is there any alternate to configure xbee's?

my materials are:

-3 xbee's link
-3 xbee usb adapter link
-3 2 dbi omni-directional antenna

my receiver arduino code is:

#include <SoftwareSerial.h>

SoftwareSerial XBEE(2,3);

void setup() {
  XBEE.begin(9600);
  Serial.begin(115200);
 
}

void loop() {

if(XBEE.available()){
  
Serial.print((char)XBEE.read());
  
     }

}

my transceiver code is:

#include <SoftwareSerial.h>

SoftwareSerial XBEE(2,3);

void setup() {
  XBEE.begin(9600);
  Serial.begin(115200);
 
}

void loop() {


XBEE.println("H");
delay(1000);

    
}

Hi, I have Xbee pro xsc s3b and I can communicate with each other on XCTU. But it doesn’t work correctly. And also I cannot communicate on Arduino. If you have found a solution about this subject can you share me ?
