4 AT COMMANDS INTERFACE

This chapter describes some differences between the AT Commands for iTegno 38XX and iTegno

3000/3045/3232. Please refer to the iTegno 38XX AT Commands Guide for more detailed information

on the AT Commands syntax and usage examples.

4.1 ATD Response

iTegno 3000/3045/3232:

“OK” is responded when a call is being answered.

iTegno 38XX:

“OK” is responded immediately when AT Command is received and processed.

Example:

iTegno 3000/3 045/3232 iTegno 38XX

ATD98765432

OK OK was responded when the

call is answered.

NO CARRIER Call hang up

ATD98765432

OK OK was responded immediately

when indicating ATD is being

processed.

NO CARRIER Call hang up

ATD90000000

NO CARRIER Call is not

successful/Busy/Rejected

ATD90000000

OK OK was responded immediately

indicating ATD is being processed.

NO CARRIER Call is not successful/Busy/Rejected

Suggested Solution:

It is advisable to use +CPAS to poll for current Call Status. The following example demonstrates using

AT+CPAS AT Command and “NO CARRIER” Response to check on Call Status.






11

iTegno 3000/3045/3232 iTegno 38XX

ATD98765432

OK “OK” was responded when the

call is answered.

AT+CPAS

+CPAS: 4 Poll for current call status

4 denotes that a call is in

process

OK

NO CARRIER The call is hanged up by

remote

AT+CPAS


0 denotes that there is no

active call

OK

ATD98765432

OK “OK” was responded immediately

indicating ATD is being processed.

AT+CPAS


4 denotes that a call is in process

OK

NO CARRIER The call is hanged up by remote

AT+CPAS


0 denotes that there is no active call

OK

4.2 AT+COPS=?

iTegno 3000/3045/3232:

When AT+COPS is executed, a new AT Command entry will not affect AT+COPS responses.

iTegno 38XX:

When AT+COPS is being executed, any other character entry will cause AT+COPS responses to

stop.






12

Example:


AT+COPS=?

+COPS: (2,"SGP-M1-3GSM", "M1-3GSM",

"52503"),(0,"SingTel", "SingTel","52501"), (3,"S

TARHUB", "STARHUB", "52505")

Note: an “a” was being entered, +COPS response

is not affected

AT+COPS=?

OK an “a” was being entered, “OK” was

responded and +COPS result will

not be responded.

4.3 SMS Storage in ME

iTegno 3000/3045/3232:

SMS messages can be saved in ME.

iTegno 38XX:

SMS messages cannot be saved in ME.

Example:


AT+CPMS=?

+CPMS: ((“SM”,”ME”,”BM”,”SR”), (“SM”,”ME”),

(“SM”,”ME”)

OK

AT+ CPMS=?

+CPMS: (“SM,“SM”,“SM”)

OK

4.4 AT+CMGL Response

iTegno 3000/3045/3232:

When SMS storage is empty, AT+CMGL returns an OK.

iTegno 38XX:

When SMS storage is empty, AT+CMGL returns “+CMS ERROR: 321” according to GSM 07.05.

In iTegno 3000/3045/3232:

AT+WRST=<mode>,<delay> is used to reset the modem in a specified time.

The <delay> parameters start from 1 minute.

In iTegno 38XX:

AT+IRST=<mode>,<delay> is used to reset the modem in a specified time. +IRST allows user to

reset the modem in terms of seconds.

Example:


AT+WRST=1,”001:03”

OK

Note: Modem reset in 1 hour and 3 minutes

AT+WRST=1,”10”

ERROR

AT+IRST=1,”001:03”

OK

Note: Modem reset in 1 hour and 3 minutes
