Introduction Lesson 1

There are many different kinds of applications SMSapplications in the market today,

and many others are ein! de"eloped. #pplications in which SMSmessa!in! can e

utili$ed are "irtually unlimited. %ome common e&amples of these are !i"en elow'

(erson-to-person te&t messa!in! is the most commonlyused SMSapplication, and it is what the SMStechnolo!y was ori!inally

desi!ned for.

)any content pro"iders make use of SMSte&t messa!es to send information

such as news, weather report, and financial data to their suscriers.

SMSmessa!es can carry inary data, and so SMScan e used as the

transport medium of wireless downloads. *+ects such as rin!tones,

wallpapers, pictures, and operator lo!os can e encoded in SMSmessa!es.

SMSis a "ery suitale technolo!y for deli"erin! alerts and notifications of

important e"ents.

SMSmessa!in! can e used as a marketin! tool.

In !eneral, there are two ways to send SMSmessa!es from a computer ( to a

moile phone'

1. onnect a moile phone or %)(/% modem to a computer (. Then use

the computer ( and #T commands to instruct the moile phone or

%)(/% modem to send SMSmessa!es.

2. onnect the computer ( to the SMScenter 0SMS or SMS!ateway of a

wireless carrier or SMSser"ice pro"ider. Then send SMSmessa!es usin! a

protocol interface supported y the SMS or SMS!ateway.

In this article, I will e&plain the first way to send, read, and delete SMSusin! #T

commands. But efore startin!, I would like to e&plain a little it aout #T

commands.

AT Commands

#T commands are instructions used to control a modem. #T is the are"iation of

#Ttention. "ery command line starts with 3#T3 or 3at3. That4s why modem

commands are called #T commands. There are two types of #T commands'

1. Basic commands are #T commands that do not start with a 353. or e&ample,D 0Dial, # 0#nswer, 7 07ook control, and * 0/eturn to online data state

are the asic commands.

2. &tended commands are #T commands that start with a 353. #ll %) #T

commands are e&tended commands. or e&ample, 5)%

0%end SMSmessa!e, 5)8 08ist SMSmessa!es, and 5)/

0/ead SMSmessa!es are e&tended commands.

If you want to !et more information aout #T commands, then you can !et it on my

other article on ode(ro+ect

Operating Modes

The SMSspecification has defined two modes in which a %)(/% modem or

moile phone can operate. They are called SMSte&t mode and SMS(D9 mode.

0(D9 stands for (rotocol Data 9nit. The mode that a %)(/% modem or moile

phone is operatin! in determines the synta& of some SMS#T commands and the

format of the responses returned after e&ecution.

I am usin! SMSte&t mode in this article.

!ntroduction to AT commands and its uses

!ntroduction

#T commands are instructions used to control a modem. #T is the are"iation of

#Ttention. "ery command line starts with 3#T3 or 3at3. That4s why modem

commands are called #T commands.

@ote that the startin! 3#T3 is the prefi& that informs the modem aout the start of acommand line. It is not part of the #T command name. or e&ample, D is the actual

#T command name in #TD, and 5)% is the actual #T command name in

#T5)%.

Tas.s Per,ormed +y AT Commands

7ere are some of the tasks that can e done usin! #T commands with a %)(/%

modem or moile phone'

et asic information aout the moile phone or %)(/% modem. or

e&ample, name of the manufacturer 0#T5)I, model numer 0#T5)),

I)I numer 0International )oile


17/31

%a"e and restore confi!urations of the moile phone or %)(/% modem.

or e&ample, sa"e 0#T5%#% and restore 0#T5/% settin!s related

to SMSmessa!in! such as the SMScenter address.

@ote that moile phone manufacturers usually do not implement all #T commands,

command parameters, and parameter "alues in their moile phones. #lso, the

eha"ior of the implemented #T commands may e different from that defined in the

standard. In !eneral, %)(/% modems desi!ned for wireless applications ha"e

etter support of #T commands than ordinary moile phones.

Types o, AT Commands

There are two types of #T commands'

1. /asic commandsare #T commands that do not start with 353. or e&ample,

D 0Dial, # 0#nswer, 7 07ook control, and * 0/eturn to online data state

are asic commands.

2. *0tended commandsare #T commands that start with 353. #ll %) #T

commands are e&tended commands. or e&ample, 5)%

0%end SMSmessa!e, 5)8 08ist SMSmessa!es, and 5)/0/ead SMSmessa!es are e&tended commands.

General Synta0 o, AT Commands

The !eneral synta& of e&tended #T commands is strai!htforward. The synta& rules

are pro"ided elow'

Synta0 rule ". #ll command lines must start with 3#T3 and end with a carria!e

return character. In a terminal pro!ram like the 7yperTerminal of )icrosoft :indows,

you can press the nter key on the keyoard to output a carria!e return character.

&ample' To list all unread inound SMSmessa!es stored in the messa!e stora!e

area, type 3#T3, then the e&tended #T command 35)83, and finally a carria!e

return character, like this'

ollapse

#T065C:C(;

Synta0 rule $. # command line can contain more than one #T command. *nly the

first #T command should e prefi&ed with 3#T3. #T commands in the same

command-line strin! should e separated with semicolons.

&ample' To list all unread inound SMSmessa!es stored in the messa!e stora!e

area and otain the manufacturer name of the moile de"ice, type 3#T3, then the

e&tended #T command 35)83, followed y a semicolon and the ne&t e&tended #T

command 35)I3'
