V. WorkingMode ofHAC-LBee/SWireless Module
5.1. Working ModeofHAC-LBee/SWireless Module
There arethree workingmodesforHAC-LBee/S.Theyare:TransparentMode,APIMode,AT
Command Mode.
5.1.1 TransparentMode
Bydefault,Modulesoperateunder transparentworking Mode.Whenoperating undertransparent
mode,themodulesactas aseriallinereplacement-all UARTdatareceivedthroughtheRXD pinis
queued up forRFtransmission. When RFdatais received, thedatais sentouttheTXD pin.
lNo serialcharacters are receivedfortheamountoftimedetermined.
lThemaximumnumber ofcharacters thatwill fit in an RFpacket(100)is received.
Serial-to-RFPacketization
DataisbufferedintheRXD bufferuntil oneofthefollowingcausesthedatatobepacketizedand
transmitted:Ifthemodulecannotimmediatelytransmit (forinstance,ifit isalreadyreceiving RF
data),theserialdataisstoredintheRXD Buffer.Thedataispacketizedand sentattimeoutorwhen
100 bytes (maximumpacketsize) are received.
Thedestination address under thetransparentmodecomposesofDH and DL.IfDHis0, and DLis
less than0xFFFF,thedatawill besentby16-bit destination address. Or it will use64-bit
destination address.
5.1.2API Mode
API(Application ProgrammingInterface)Operation isanalternativetothedefault Transparent
Operation. Theframe-basedAPIextends theleveltowhichahostapplication caninteractwiththe
networkingcapabilities ofthemodule.
WheninAPImode,all dataenteringand leavingthemoduleiscontainedinframesthatdefine
operations orevents within themodule.
Transmit DataFrames (received through theRXDpin (pin 3)) include:
•RFTransmit DataFrame
•Command Frame(equivalenttoATcommands)
ReceiveDataFrames(sentouttheTXD pin (pin 2)) include:
•RF-received dataframe
•Command response
•Eventnotifications such as reset, associate, disassociate, etc.
TheAPIprovidesalternativemeans ofconfiguringmodulesandrouting dataatthehostapplication
layer.Ahostapplication cansend dataframestothemodulethatcontainaddress and payload

information insteadofusingcommand modetomodifyaddresses. Themodulewill send data
frames to theapplication containingstatus packets;as well assource, RSSIand payload information
fromreceiveddatapackets. TheAPIoperationoption facilitatesmanyoperations suchasthe
examples cited below:
•Transmittingdatato multipledestinations withoutenteringCommand Mode
•Receivesuccess/failurestatus ofeach transmitted RFpacket
•Identifythesourceaddress ofeach received packet
* Howto let themoduleworkundertheAPImodeafterpowerup?
User can useATcommand to enter theAPImode.Thesetup steps areshown as follow:
Enter theATCommand page
Inputthe3-character command sequence “+++”and wait forthereply “OK”frommodule.
Input “ATAP1<CR>”command, themodulewill reply “OK”.Itisusedtosetthemoduleworking
under APImode.
Input “ATWR<CR>”command, themodulewillreply “OK”.Itisusedtosavethesetting.Sothe
modulewill enter APImodeautomaticallywhenrestartthemodulenexttime.
Input “ATCN<CR>”command toexit fromtheATCommand mode.Now,themoduleworks under
theAPImode. Even power up themoduleagain, it still enters theAPImodedirectly.
5.1.3ATCommand Mode
To modifyorread RFModuleparameters, themodulemustfirstenter intoCommand Mode-astate
inwhichincomingcharactersareinterpretedascommands. TwoCommand Modeoptions are
supported:ATCommandMode[refer to section below]and APICommand Mode
Send the3-character command sequence “+++”and observeguardtimesbefore and afterthe
command characters.
NOTE:Failure toenterATCommand Modeismostcommonlyduetobaud ratemismatch. Ensure
the ‘Baud settingon the “PC Settings”tabmatchestheinterface datarateoftheRFmodule.By
default, theBDparameter=3 (9600 bps).
To readaparameter valuestored in theRFmodule s register, omit theparameter field.
TheprecedingexamplewouldchangetheRFmoduleChannelto “0x0B”.Tostore thenewvalueto
non-volatile(longterm)memory, subsequentlysend theWR(Write) command.
Formodifiedparameter valuestopersistinthemodule sregistryafter areset,changesmustbe

savedtonon-volatilememoryusingtheWR(Write) Command. Otherwise,parametersare restored
to previouslysaved values after themoduleis reset.
SystemResponse:Whenacommand issenttothemodule,themodulewill parseand executethe
command. Upon successfulexecution ofacommand, themodulereturns an “OK”message.If
execution ofacommand results in an error, themodulereturns an “ERROR”message.
NOTE: Someparameterswill validateatonce after setting,butsomeparameterswill validateafter
restartthemodule. So pleasereadeveryATcommand verycarefully.
To ExitATCommand Mode:
Send theATCN(Exit Command Mode) command(followed byacarriagereturn). [OR]
Ifno validATCommands are received within 10 seconds.
5.1.4 Howto select theworking mode
Thedefault settingin thefactoryis transparentworkingmode.
1. Under thetransparentmode,input3-character command sequence “+++”fromserialport,it will
changefortheATCommand mode.
2. Whenyou selectthetransparentworkingmode(ATAP0),inputting “ATCN”command canexit
fromtheATCommand modeand enterthetransparentmode.Orwhenyou selectthetransparent
working mode(ATAP0),ifthereisno inputin10 seconds, themodulewill exit fromtheAT
Command modeand enter thetransparentmode.
3. Whenyou selecttheAPIworkingmode(ATAP1), inputting “ATCN”command can exit fromthe
ATCommand modeand enter theAPImode.Or whenyou selecttheAPIworking mode(ATAP1),
ifthere isnoinputin10seconds, themodulewillexit fromtheATCommand modeandenterthe

4. UndertheAPImode,input3-charactercommand sequence “+++”will letthemoduleswitchto
ATCommand mode.
5. Under APImode, when usingATCommand tosetup transparentmode(ATAP0), themodulewill
switch to transparentmode.
