Python example "Hello world", how does it work?

Hello everyone,
I am a new beginer with Digi ESP. I am trying to do a simple test using ESP python sample XbeeHello.py to establish communication between two ConnectPort Xfamily devices.
As wirten from the Python Programing Guid, I want to send “Hello, world!” to a fixed node address. I loaded below python example into ConnectPort X4 to run with DESTINATION address modified, and sent the"Hello world" to my ConnectPortX2 device.
import sys, os
import xbee
from socket import *

The Format of the tuple is:

(address_string, endpoint, profile_id, cluster_id)

The values for the endpoint, profile_id, and

cluster_id given below are the values used to write

to the serial port on an Ember-based XBee module.

DESTINATION=(“00:13:a2:00:40:4a:3b:5c!”, 0xe8, 0xc105, 0x11)

Create the socket, datagram mode, proprietary transport:

sd = socket(AF_XBEE, SOCK_DGRAM, XBS_PROT_TRANSPORT)

Bind to endpoint 0xe8 (232):

sd.bind((“”, 0xe8, 0, 0))

Send “Hello, World!” to the destination node, endpoint,

using the profile_id and cluster_id specified in

DESTINATION:

sd.sendto(“Hello, World!”, 0, DESTINATION)

After that I want to receive "Hello world " from my desitination address which is the ConnectPortX2 device. what should I do? Should I use the reading and wirting example to receive and payload back? I am not sure how to do next step. I tried many time from theTelnet, however, it doesn’t work.
Can any one help me?
Thank in advance…

you would need to have a python app running on the X2 that would receive the ‘hello world’ zigbee packet. it will be something like:
payload, address = sd.recv(160)
