#XBee#XCTU#직비#지그비
■ZigBee is a specification/standard for a suite of high level communication protocols using small, low-power digital radios.
Think of Bluetooth but for low-power devices.
■XBee is the brand name from DIGI International for various radio modules.
■XBee Series 1 or XBee 802.15.4, the original XBee radio, quite simple to use, does point to point and point-to-multipoint.
■XBee ZNet 2.5, is actually a Series 2 module with older firmware. Series 2 and 2.5 are compatible via firmware updates.
■XBee Series 2 or XBee ZB, uses the ZigBee mesh networking protocol. The latest version available from Digi.
■Pro versions, for all series, have just increased output power capabilities, thus longer range.

Step1 : Download X-CTU Software
Step2 : Put together your XBee breakout board
Step3 : Configure 1st XBee as a Coordinator
Step4 : Configure 2nd XBee as a Router
Step5 : Test the configuration
.
.
.
Step3
After selecting the proper COM port click the Test/Query button.
After selecting the Test/Query button,
you should see a dialogue box like the one below.
You will want to record the serial number shown as you will need it in a couple minutes.
After recording the serial number you can click OK.
Next, select the Modem Configuration tab at the top of the window.
Once here, select the read button.
This will bring up the current configuration for the connected XBee.
★XBP24-ZB는 XBee Pro Series2 모델이다.
Once here, you want to select Zigbee Coordinator AT in the function set drop down menu.
Coordinator, Router, EndDevice가 표시된다.
Function Set에서 Role을 바꿔주고 Write버튼을 눌러주면 Role이 바뀐다.
After selecting the coordinator function set, you will need to set the PAN ID.
This can be any four digit number and allows the XBees to distinguish
between modules in their network and those from other networks.
Once you have added the wanted PAN ID click the "Write" button. This will update and configure the XBee.
Once this is done you can disconnect the XBee and plug in the second XBee.
Step4
To configure the 2nd XBee,
you will follow the same process as for the coordinator with one difference.
In the PC settings tab, again, click the "Test/Query" button and record the serial number.
Then in the Modem configuration tab, click the read button to load the current configuration of the XBee and set the PAN ID to the same ID used for the coordinator. The only change will be the function set you choose.
For the second XBee we will set this as Zigbee Router AT.
After setting the PAN ID and the function set for the router
you will put the recorded serial numbers to use.
Enter the first 6 digits of the coordinators serial number
into the Destination Address High field
and the rest of the serial number
into the Destination Address Low field.
13A200 + 40318C1A
Then select the "Write" button to update the configuration settings for the router.
Once this is done updating you can disconnect the router and reconnect the coordinator to the computer.
After re-connecting the coordinator to the computer,
you will again go into the Modem Configuration tab and click the read button.
You will then want to set the Destination Address to the serial number of the Router XBee in the same manner as you just did for the Router.
Coordinator와 Rounter간의 Serial Number를 서로 지목해준다.
Router의 Serial Number는 13A200+40318C3D 이다.
Once done you will again click the write button to update the coordinator XBee settings.
After the write process is complete you are ready to use your XBees and communicate wirelessly!
Step5
A simple test can be done to be sure the two XBees are communicating properly.
You can connect either one of the XBees to the computer.
Then, connect the second XBee to 3.3V power and connect the Dout and Din pins together.
This will cause the XBee to automatically retransmit any data it receives.
When you have both XBees connected go to the Terminal tab in the X-CTU window.
Whatever you type in the terminal
window will appear in blue font
and whatever is received will appear in red font.
If the XBees are configured correctly every character you type should be mirrored in red.
When typing single characters, you should see a screen similar to the one above.
To send strings of data you can assemble a data packet.
To do this click the "Assemble Packet" button and type the wanted string into the box then click send data.
This will send the entire packet before receiving the same packet back.
If everything you type is being reflected back in red, you are successfully transmitting and receiving with your XBees!! You are now ready to use them however you wish.
You can connect them to any microcontroller and transmit data through the UART peripheral or you can connect each XBee to a different computer and have a chat application. There are many more possibilities that are now at your fingertips with your working XBees.

Q:: How can I configure an Series 1 Xbee to act as a Router between End Device and a Coordinator?
A:: That is not possible. In the 802.15.4 protocol there are only two roles: coordinator and end device.
If you want to have routers, you should use other protocol like ZigBee (XBee Series 2).
