FI
Between Customer Application and the Module, standardized RS–232 interface is used for the
communication, and default values for the interface settings as following:
AT command syntax
FI
D
EN
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.
C
O
N
In the present document, AT commands are divided into three categories: Basic Command, S Parameter
Command, and Extended Command.
1. Basic Command
O
M
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 “ATE<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.
C
2. S Parameter Command
SI
M
The format of S Parameter Command is “ATS<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 “ATS<n>”, and then a
default value is assigned.
3. Extended Command
The Extended Command has several formats, as following table list:

This command is only available during a connecting PS data call. The +++ character sequence
causes the TA to cancel the data flow over the AT interface and switch to Command Mode. This
allows to enter AT commands while maintaining the data connection to the remote device.
NOTE: To prevent the +++ escape sequence from being misinterpreted as data, it must be preceded
and followed by a pause of at least 1000 milliseconds, and the interval between two ‘+’ character
can’t exceed 900 milliseconds.

This command is used to select the level of functionality <fun> in the ME. Level "full
functionality" is where the highest level of power is drawn. "Minimum functionality" is where
minimum power is drawn. Level of functionality between these may also be specified by
manufacturers. When supported by manufacturers, ME resetting with <rst> parameter may be
utilized.
NOTE: AT+CFUN=6 must be used after setting AT+CFUN=7. If module in offline mode, must
execute AT+CFUN=6 or restart module to online mode.
NOTE: The set value in Write Command will take efficient immediately; The set value will be lost
after module reset except <fun>=5;
NOTE: The response will be returned immediately for Test Command and Read Command; The
maximum response time for Write Command is 2 minutes.

This command is used to send the ME a password which is necessary before it can be operated
(SIM PIN, SIM PUK, PH-SIM PIN, etc.). If the PIN is to be entered twice, the TA shall
automatically repeat the PIN. If no PIN request is pending, no action is taken towards MT and an
error message, +CME ERROR, is returned to TE.
If the PIN required is SIM PUK or SIM PUK2, the second pin is required. This second pin,
<newpin>, is used to replace the old pin in the SIM.
NOTE: The set value in Write Command will take efficient immediately;
NOTE: The response will be returned immediately for Test Command and Read Command; The

By using AT+CRSM instead of Generic SIM Access AT+CSIM, TE application has easier but
more limited access to the SIM database.
Write command transmits to the MT the SIM <command> and its required parameters. MT handles
internally all SIM-MT interface locking and file selection routines. As response to the command,
MT sends the actual SIM information parameters and response data. MT error result code +CME
ERROR may be returned when the command cannot be passed to the SIM, but failure in the
execution of the command in the SIM is reported in <sw1> and <sw2> parameters.
NOTE: The response will be returned immediately for Test Command; The maximum response

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+COPS?) 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.

The set command controls the presentation of an unsolicited result code +CEREG: <stat> when
<n>=1 and there is a change in the MT's EPS network registration status in E-UTRAN, or
unsolicited result code +CEREG: <stat>[,<tac>,<ci>[,<AcT>]] when <n>=2 and there is a change
of the network cell in E-UTRAN; in this latest case <AcT>, <tac> and <ci> are sent only if
available.
NOTE 1: If the EPS MT in GERAN/UTRAN/E-UTRAN also supports circuit mode services and/or
GPRS services, the +CREG command and +CREG: result codes and/or the +CGREG command
and +CGREG: result codes apply to the registration status and location information for those
services.
The read command returns the status of result code presentation and an integer <stat> which shows
whether the network has currently indicated the registration of the MT. Location information
elements <tac>, <ci> and <AcT>, if available, are returned only when <n>=2 and MT is registered
in the network.
NOTE: The set value in Write Command will take efficient immediately; The set value will be lost

party when receiving a mobile terminated call.
Write command enables or disables the presentation of the CLI at the TE. It has no effect on the
execution of the supplementary service CLIP in the network.
When the presentation of the CLI at the TE is enabled (and calling subscriber allows), +CLIP:

This command refers to CLIR-service that allows a calling subscriber to enable or disable the
presentation of the CLI to the called party when originating a call.
Write command overrides the CLIR subscription (default is restricted or allowed) when temporary
mode is provisioned as a default adjustment for all following outgoing calls. This adjustment can be
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.
Read command gives the default adjustment for all outgoing calls (given in <n>), and also triggers

This command refers to the GSM/UMTS supplementary service COLP(Connected Line
Identification Presentation) that enables a calling subscriber to get the connected line identity
(COL) of the called party after setting up a mobile originated call. The command enables or
disables the presentation of the COL at the TE. It has no effect on the execution of the
supplementary service COLR in the network.
When enabled (and called subscriber allows), +COLP:<number>, <type> [,<subaddr>, <satype>
[,<alpha>]] intermediate result code is returned from TA to TE before any +CR responses. It is
manufacturer specific if this response is used when normal voice call is established.
When the AT+COLP=1 is set, any data input immediately after the launching of “ATDXXX;” will
stop the execution of the ATD command, which may cancel the establishing of the call.
NOTE: The set value in Write Command will take efficient immediately; The set value will be lost
after module reset.

in voice mode of operation (active voice call).
NOTE: The END event of voice call will terminate the transmission of tones, and as an operator
option, the tone may be ceased after a pre-determined time whether or not tone duration has been
reached.

This command is used to adjust the aggressiveness of EC in the high band (4 ~ 8 kHz). A higher
value is more aggressive and suppresses more high-band echo. Q-format - Q4.11WB_gamma_E =
2048 * gammaWhere gamma is in the range [0,15]. It modify the WB_gamma_e of
TX_VOICE_SMECNS in DSP. The bigger the value, the stronger the inhibition .This command

This command allows the TE to specify a Packet Filter - PF for a Traffic Flow Template - TFT that
is used in the GGSN in UMTS/GPRS and Packet GW in EPS for routing of packets onto different
QoS flows towards the TE. The concept is further described in the 3GPP TS 23.060 [47]. A TFT
consists of from one and up to 16 Packet Filters, each identified by a unique <packet filter
identifier>. A Packet Filter also has an <evaluation precedence index> that is unique within all TFTs
associated with all PDP contexts that are associated with the same PDP address.

LE
The test command returns values supported as a compound value.
The read command returns the current settings for each defined context for which a QOS was
explicitly specified.
The write command allows the TE to specify a Quality of Service Profile for the context identified
by the context identification parameter <cid> which is used when the MT sends an Activate PDP
Context Request message to the network.
A special form of the write command, AT+CGEQREQ=<cid> causes the requested profile for
context number <cid> to become undefined.

Every time the SIM Application issues a Proactive Command, via the ME, the TA will receive an
indication. This indicates the type of Proactive Command issued.
AT+STGI must then be used by the TA to request the parameters of the Proactive Command from
the ME. Upon receiving the +STGI response from the ME, the TA must send AT+STGR to confirm
the execution of the Proactive Command and provide any required user response, e.g. a selected
menu item.
NOTE: The response will be returned immediately for Test Command and Read Command.

AT+CGPS
Start/Stop GPS session
LE
17.1
Description
FI
D
EN
IT
AL
FI
This command is used to start or stop GPS session.
NOTE:
1. Output of NMEA sentences is automatic; no control via AT commands is provided. At
present the module only supports standalone mode. If executing AT+CGPS=1, the GPS
session will choose cold or hot start automatically.
2. UE-based and UE-assisted mode depend on URL (AT+CGPSURL). When UE-based
mode fails, it will switch standalone mode.
3. UE-assisted mode is singly fixed. Standalone and UE-based mode is consecutively
fixed.
4. After the GPS closed, it should to wait about 2s~30s for start again. Reason：If the
NO
C
O
N
signal conditions are right (strong enough signals to allow ephemeris demodulation) or
ephemeris demodulation is on going, sometimes MGP will stay on longer in order to
demodulate more ephemeris. This will help the engine provide faster TTFF and
possibly better yield later (up to 2 hours), because it has the benefit of more ephemeris
available.
