In this document, a short description, the syntax, the possible setting values tia 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 n the previous document. e 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 fid included in this document.

2 AT Interface Synopsis
ile 2.1 Interface settings Between Customer Application and the Module, standardized RS232 interface is used for the F communication, and default values for the interface settings as following: l 115200bps, 8 bit data, no parity, 1 bit stop, no data stream control.
tia 2.2 AT command syntax The prefix "AT" or "at" (no case sensitive) must be included at the beginning of each command line n (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. e When Customer Application issues a series of AT commands on separate command lines, leave a pause fid 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
n Command, and Extended Command. Co 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 "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.
m 2. S Parameter Command o The format of S Parameter Command is "ATS<n>=<m>", "<n>" is the index of the Sregister 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
C default value is assigned. IM3. Extended Command S The Extended Command has several formats, as following table list:

information about the command subparameters. Check the current values of subparameters. Set user-definable subparameter values. Read non-variable subparameters determined by internal processes.
F NOTE: The character "+" between the prefix "AT" and command name may be replaced by other
character. For example, using "#" or "$"instead of "+".
tial 2.3 Information responses
If the commands included in the command line are supported by the Module and the subparameters are
n 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.
e 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>.
Confid Throughout this document, only the responses are presented, and <CR><LF> are intentionally omitted.

This command is used to disconnect existing call. Before using ATH command to hang up a voice
Ccall, it must set AT+CVHU=0. Otherwise, ATH command will be ignored and "OK" response is
given only.
This command is also used to disconnect PS data call, and in this case it doesn't depend on the

2019-11-21
Smart Machine Smart Decision
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.
l 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.
tia 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
n <mode>s and <format>s. These lists shall be delimited from the operator list by two commas.

This command refers to supplementary service related network initiated notifications. The set
command enables/disables the presentation of notification result codes from TA to TE.
When <n>=1 and a supplementary service notification is received after a mobile originated call
setup, intermediate result code +CSSI: <code1>[,<index>] is sent to TE before any other MO call
setup result codes presented in the present document. When several different <code1>s are received
from the network, each of them shall have its own +CSSI result code.
When <m>=1 and a supplementary service notification is received during a mobile terminated call
setup or during a call, or when a forward check supplementary service notification is received, unsolicited result code +CSSU: <code2>[,<index>[,<number>,<type>[,<subaddr>,<satype>]]] is sent to TE. In case of MT call setup, result code is sent after every +CLIP result code (refer
l command "Calling line identification presentation +CLIP") and when several different <code2>s
are received from the network, each of them shall have its own +CSSU result code.

12 AT Commands for GPS
12.1 AT+CGPS Start/Stop GPS session
Description
This command is used to start or stop GPS session. NOTE:
l 1. Output of NMEA sentences is automatic; no control via AT commands is provided. At tia 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.
n 3. UE-assisted mode is singly fixed. Standalone and UE-based mode is consecutively
fixed.
e 4. After the GPS closed, it should to wait about 2s~30s for start again. ReasonIf the fid 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
n available.

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:
