and responses, and some examples of AT commands are presented.

Prior to using the Module, please read this document and the Version History to know the difference

from the previous document.

In order to implement communication successfully between Customer Application and the Module, it

is recommended to use the AT commands in this document, but not to use some commands which are not

included in this document.

1.4 Definitions and conventions

1. For the purposes of the present document, the following syntactical definitions apply:

<CR> Carriage return character. <LF> Linefeed character.

SIM5350_ATC_V1.02 6/9/2014

SIM5350 AT Command Set

<…> Name enclosed in angle brackets is a syntactical element. Brackets themselves do not

appear in the command line.

[…] Optional subparameter of AT command or an optional part of TA information response

is enclosed in square brackets. Brackets themselves do not appear in the command line. If subparameter is not given, its value equals to its previous value or the recommended default value.

underline Underlined defined subparameter value is the recommended default setting or factory

setting.

2. Document conventions:

♦ Display the examples of AT commands with Italic format. ♦ Not display blank-line between command line and responses or inside the responses. ♦ Generally, the characters <CR> and <LF> are intentionally omitted throughout this document. ♦ If command response is ERROR, not list the ERROR response inside command syntax.

NOTE: AT commands and responses in figures may be not following above conventions.

3. Special marks for commands or parameters:

SIM PIN – Is the command PIN protected?

YES – AT command can be used only when SIM PIN is READY.

– AT command can be used when SIM card is absent or SIM PIN validation is

pending.

References – Where is the derivation of command?

SIM5350 AT Command Set

2 AT Commands Interface Synopsis

2.1 Interface settings

Between Customer Application and the Module, standardized RS–232 interface is used for the

communication, and default values for the interface settings as following:

115200bps, 8 bit data, no parity, 1 bit stop, no data stream control.

2.2 AT command syntax

The prefix “AT” or “at” (no case sensitive) must be included at the beginning of each command line

(except A/ and +++), and the character <CR> is used to finish a command line so as to issue the command

line to the Module. It is recommended that a command line only includes a command.

When Customer Application issues a series of AT commands on separate command lines, leave a pause

between the preceding and the following command until information responses or result codes are retrieved

by Customer Application, for example, “OK” is appeared. This advice avoids too many AT commands are

issued at a time without waiting for a response for each command.

In the present document, AT commands are divided into three categories: Basic Command, S Parameter

Command, and Extended Command.

1. Basic Command

The format of Basic Command is “AT<x><n>” or “AT&<x><n>”, “<x>” is the command name, and

“<n>” is/are the parameter(s) for the basic command, and optional. An example of Basic Command is

“AT E <n>”, which informs the TA/DCE whether received characters should be echoed back to the TE/DTE

according to the value of “<n>”; “<n>” is optional and a default value will be used if omitted.

2. S Parameter Command

The format of S Parameter Command is “AT S<n>=<m>”, “<n>” is the index of the S–register to set,

and “<m>” is the value to assign to it. “<m>” is optional; in this case, the format is “AT S<n>”, and then a

default value is assigned.

3. Extended Command

The Extended Command has several formats, as following table list:

Table 2-1: Types of Extended Command

Command T y pe Syntax Comments

SIM5350_ATC_V1.02 6/9/2014

SIM5350 AT Command Set

Test Command AT+<NAME>=? Test the existence of the command; give some

information about the command subparameters.

Read Command AT+<NAME>? Check the current values of subparameters.

Write Command AT+<NAME>=<…> Set user-definable subparameter values.

Execution Command AT+<NAME> Read non-variable subparameters determined by

internal processes.

NOTE: The character “+” between the prefix “AT” and command name may be replaced by other

character. For example, using “#” or “$”instead of “+”.

2.3 Information responses

If the commands included in the command line are supported by the Module and the subparameters are

correct if presented, some information responses will be retrieved by from the Module. Otherwise, the

Module will report “ERROR” or “+CME ERROR” or “+CMS ERROR” to Customer Application.

Information responses start and end with <CR><LF>, i.e. the format of information responses is

“<CR><LF><response><CR><LF>”. Inside information responses, there may be one or more <CR><LF>.

Throughout this document, only the responses are presented, and <CR><LF> are intentionally omitted.

revoked by using the opposite command.. If this command is used by a subscriber without

provision of CLIR in permanent mode the network will act.

Description

This command allows the control the following call related services:

1. A call can be temporarily disconnected from the ME but the connection is retained by the

network.

2. Multiparty conversation (conference calls).

3. The served subscriber who has two calls (one held and the other either active or alerting)

can connect the other parties and release the served subscriber's own connection.

Calls can be put on hold, recovered, released, added to conversation, and transferred. This is

based on the GSM/UMTS supplementary services.

5.2 AT+COPS Operator selection

Description

Write command forces an attempt to select and register the GSM/UMTS network operator. <mode>

is used to select whether the selection is done automatically by the ME or is forced by this

command to operator <oper> (it shall be given in format <format>). If the selected operator is not

available, no other operator shall be selected (except <mode>=4). The selected operator name

format shall apply to further read commands (AT+ C O PS ?) also. <mode>=2 forces an attempt to

deregister from the network. The selected mode affects to all further network registration (e.g. after

<mode>=2, ME shall be unregistered until <mode>=0 or 1 is selected).

Read command returns the current mode and the currently selected operator. If no operator is

selected, <format> and <oper> are omitted.

Test command returns a list of quadruplets, each representing an operator present in the network.

Quadruplet consists of an integer indicating the availability of the operator <stat>, long and short

alphanumeric format of the name of the operator, and numeric format representation of the operator.

Any of the formats may be unavailable and should then be an empty field. The list of operators shall

be in order: home network, networks referenced in SIM, and other networks.

It is recommended (although optional) that after the operator list TA returns lists of supported

<mode>s and <format>s. These lists shall be delimited from the operator list by two commas.

When executing AT+COPS=? , any input from serial port will stop this command.
