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:

ia
115200bps, 8 bit data, no parity, 1 bit stop, no data stream control.
id
e
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.
C
on
f
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
C
om
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.
2. S Parameter Command
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.
SI
3. Extended Command
The Extended Command has several formats, as following table list:

This command is used to control the SIM card directly.
Compared to restricted SIM access command AT+CRSM, AT+CSIM allows the ME to take more
control over the SIM interface.
For SIM–ME interface please refer 3GPP TS 11.11.
NOTE：The SIM Application Toolkit functionality is not supported by AT+CSIM. Therefore the
following SIM commands can not be used: TERMINAL PROFILE, ENVELOPE,
FETCH and TEMINAL RESPONSE.

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.

Write command forces an attempt to select and register the 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.
When executing AT+COPS=? , any input from serial port will stop 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.

12 AT Commands for GPS
Start/Stop GPS session
Description
SIM PIN
NO
C
on
f
id

nt
ia
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
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.

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.

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
an interrogation of the provision status of the CLIR service (given in <m>).
Test command returns values supported as a compound value.
