Quick Start to Xbee Wireless Communication modules by Digi International. (XB24-AWI-001)


This post will provide a Quick start guide to Xbee RF module from Digi International. I am working on XB24-AWI-001-ND module. it has just 1mW transmitting power. This post is just to start communicating wirelessly through Xbees devices. You need a serial port, 3.3V supply a resistor, wires, SIL (Single in line) connectors, breadboard and a terminal software nothing else.

You just need to see the pin out page on datasheet. I just used some basic Pins for quick start which are shown in table given below.

Sr.
Pin Number
PIN description
1.
1
Vcc 3.3V
2.
2
DOUT (TXD data OUT)
3.
3
DIN (RXD data IN)
4.
5
RST (Reset active low 50kΩ pullup)
5.
10
GND

 Schematic is very simple to understand. As shown in figure 1. Pin1 is connected to Vcc 3.3V. Pin5 pulledup through a resistor of 50kΩ. Pin10 is connected with Ground. Pin2 TXD is connected with RXD of serial port while Pin 3 is connected with TXD of serial port. I am using a dual Port Custom made serial Com Port. You may order this from Seeed.

Figure 1. Basic Schematic.

When you setup all the wiring carefully. You just switch ON the supply. And here you go for basic communication I used Docklight as terminal software. You may use Hyperterminal or any other. Configure the serial port as 9600bps, 8bits, no parity and no flow control. Now you don’t need to configure these module for quick start. They are configured to factory settings Just type in one terminal and receive that string in second one or vice versa. If you want to make a personal area network (PAN) and want that no one is interrupting your network then you may configure them with PAN ID and addresses. But for the very basic communication you don’t need to configure them. This post is all about the first impression that I got from XBee modules very impressive I just need to check and use these module for the first time.

In the following figure 2. We have two Xbee modules connected with a dual USB serial port.

Figure 2. Setup.

In the following figure 3. We have Docklight. Top one is for left Xbee module. And second one is for right Xbee module according to figure 2. Now according to Docklight default setting the strings shown in red colour is received by the terminal and with blue is transmitted by terminal.

Figure 3. Docklight Communication.

In the following video you will get an idea very clearly.
