Introduction
ThankyouforpurchasinganXBeeWi‐FiDevelopmentKit.Thiskitisdesignedtomakeiteasytosetupan
XBeeWi‐Finetwork,senddatafromoneXBeetotheother,andadjusttheXBeesettings.Beforeyoustart
workingwiththekit,let'scoversomebasics.
Goals of the Kit
Asyougothroughthestepsinthiskit,youwill:
Requirements of the Kit
System Requirements
Toinstallthesoftwarementionedinthisguide,youwillneedaPCrunningMicrosoftWindows
2000,XP,VistaorWindows7.
Additional Requirements
Thisguideassumestheuseofan802.11bgnaccesspointorwirelessrouter(notprovided)with
WPA,orWPA2withPSKandDHCPenabled.TheXBeeWi‐FidoesnotsupportWEPorenterprise
encryption.
Further,thisguideassumesbothmodulesareconnectedtothesameaccesspointorrouter.
WhileitispossibletoconnecttheXBeeWi‐Fitodifferentaccesspointsorrouters,itisbeyond
thescopeofthisguide.ForinformationoncommunicationacrossaccesspointsseetheUser's
Manual.
1.SetupyourXBeeWi‐FiDevelopmentKit.
2.DownloadandinstallX‐CTUconfigurationsoftware.
3.UseX‐CTUtoestablishan802.11bgnnetworkconnectionbetween
theXBeeWi‐Fimodulesusinganaccesspointorwirelessrouter.
4.PuttheXBeeWi‐Fimoduleintodeepsleepmode.

Assemble your XBee Wi-Fi Development Kit
AssemblethekitbyplacingoneXBeeWi‐FimoduleoneachoftheXBeeUSBDevelopmentBoardsas
showninthediagrambelow.ConnecttheU.FLantennatotheU.FLXBeeasshown.ConnecttheUSB
cabletotheXBeeUSBDevelopmentBoard;itwillbeattachedtothecomputerinalaterstep.
Notes:
1.TheantennaisonlyinstalledonU.FLmodules.ThePCBantennamodulecomesequipped
withanantennaalreadyonthemodule.
2.ModulesareinstalledbyaligningpinsandpressingintotheXBeeUSBDevelopmentBoard
socket.
3.ModulescanberemovedfromtheXBeeUSBDevelopmentBoardsocketbycarefully
applyingupwardpressuretothemodule.
4.Thepowersupplyjackisonthelowerleftcorneroftheboard.Itisnotrequiredforthis
module.ThisguideassumestheboardispoweredbyaUSBcableconnectedtothe
computer.

Part 2: Download and Install X-CTU Software
ForproperkitconfigurationandoperationX‐CTUsoftware(version5.15orlater)mustbedownloaded
andinstalled.AcopyofX‐CTUsoftwareandUSBdriverswillneedtobeoneachcomputerusedin
conjunctionwiththisguide.
Installing USB Drivers
TheXBeeUSBinterfaceboardisa"plug‐and‐play"devicethatshouldbedetectedbythePC
automatically.IfyouareusingWindows7orVista,theUSBdriversshouldautomaticallyinstallanda
notificationwillappearinthelowerrightportionofyourscreenindicatingsuccessorfailure.IftheUSB
driversfailtoinstall,pleasefollowtheUSBdriverinstallationinstructionsfoundhere:
http://www.digi.com/support/kbase/kbaseresultdetl.jsp?id=3214.

Part 3: Establish an 802.11 bgn Network
Connection
Twotypesofnetworkconnectionareavailable.Thefirstisad‐hocwhereatwomodulenetworkis
establishedwithouttheaidofanaccesspointorrouter.Thismodeisnotdiscussedinthisguide.Further
informationonad‐hocnetworksisavailableintheUser'sManual.Thesecondtypeofnetworkiscreated
usinganaccesspointorrouter.Thebasicsofthistypeofconnectionwillbecoveredinthissection.
Starting the X-CTU Software
1.ConnecttheXBeeUSBDevelopmentBoardUSBcabletothecomputer.
2.GotothefilewhereyousavedtheX‐CTUsoftware.
3.Double‐clickonX‐CTU.exetostarttheprogram.

Running the X-CTU Software
1.UnderthePCSettingstab,selectthePCserialCOMportthatwillbeused(USBSerialPort(COM4)
inthiscase.TheUSBportswillbelabeledas“USBSerialPort”andareassignedanumberbasedon
yourPC'ssettings.
2.SetthefollowingvaluesintheComPortSetupsectionofX‐CTU:
BaudRate: 9600
FlowControl: None
DataBits: 8
Parity: None
StopBits: 1

Note:TheX‐CTUbaudratemustmatchthemodule'sBDparameterforproper
communication.Themoduledefaultis9600baud.

Part 4: 
Put the XBee Module into Deep Sleep Mode
Twotypesofsleepareavailableonthemodule;thefirstisassociatedsleep.Inassociatedsleepmodethe
modulewillremembertheconnectiontothelastaccesspointorrouteritwasconnectedto.Formore
informationonassociatedsleepseetheUser'sManual.
Thesecondtypeofsleepisdeepsleep;deepsleepmodewillcompletelypowerdowntheWi‐Fiportion
ofthemodule.DeepsleepisthelowestcurrentmodefortheXBeeWi‐Fimodule.
ToenterdeepsleepandwakeuptheXBeeWi‐Fimoduleperformthefollowingsteps:
