1.4 Definitions and Conventions
1. Definitions
For the purposes of the present document, the following syntactical definitions apply:
<CR> Carriage return character.
<LF> Linefeed character.
<…> 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 and defined subparameter value is the recommended default setting or factory setting.
Parameter Saving Mode
NO_SAVE : The parameter of the current AT command will be lost if module is rebooted or current AT command doesn't have parameter.
AUTO_SAVE : The parameter of the current AT command will be kept in NVRAM automatically and take in effect immediately, and it won't be lost if module is rebooted.
AUTO_SAVE_REBOOT: The parameter of the current AT command will be kept in NVRAM automatically and take in effect after reboot, and it won't be lost if module is rebooted.
AT&W_SAVE : The parameter of the current AT command will be kept inusersetting_save.nvm by sending the command of "AT&W".
Max Response Time
Max response time is estimated maximum time to get response, the unit is seconds.
2. Document Conventions
Generally, the characters <CR> and <LF> are intentionally omitted throughout this document.
www.simcom.com

A76XX Series_AT Command Manual_V1.07
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.
1.5 AT Interface Synopsis
1.5.1 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.
1.5.2 AT Commands Syntax
The "AT" or "at" or "aT" or "At" prefix 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 Examples, "OK" is appeared. This advice avoids too many AT commands are issued at a time without waiting for a response for each command.
The AT Command set implemented by A7600 Series is a combination of 3GPP TS 27.005, 3GPP TS 27.007
and ITU-T recommendation V.25ter and the AT commands developed by SIMCom.
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>", where "<x>" is the command name, and www.simcom.com
40 / 632
A76XX Series_AT Command Manual_V1.07
"<n>" is/are the parameter(s)for the basic command which is optional. An Examples 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 syntax
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 Syntax
The Extended Command has several formats, as following table list:
Table 1: Types of AT commands and responses
Test Command
AT+<x>=?
Read Command
AT+<x>?
Write Command
AT+<x>=<…>
Execution Command
AT+<x>
The mobile equipment returns the list of parameters and value ranges set with the corresponding Write Command or by internal processes.
This command returns the currently set value of the parameter or parameters.
This command sets the user-definable parameter values.
The execution command reads non-variable parameters affected by internal processes in the GSM engine.
NOTE
The character "+" between the prefix "AT" and command name may be replaced by other character. For
Examples, using "#" or "$"instead of "+".
4. Combining AT commands on the same Command line
You can enter several AT commands on the same line. In this case, you do not need to type the "AT" or "at" prefix before every command. Instead, you only need type "AT" or "at" the beginning of the command line.
Please note to use a semicolon as the command delimiter after an extended command; in basic syntax or S parameter syntax, the semicolon need not enter, for Examples:
ATE1Q0S0=1S3=13V1X4;+IFC=0,0;+IPR=115200.
The Command line buffer can accept a maximum of 3071 characters (counted from the first command without "AT" or "at" prefix). If the characters entered exceeded this number then none of the Command will executed and TA will return "ERROR".
5. Entering successive AT commands on separate lines
When you need to enter a series of AT commands on separate lines, please Note that you need to wait the final response (for Examples OK, CME error, CMS error)of last AT Command you entered before you enter www.simcom.com
41 / 632
A76XX Series_AT Command Manual_V1.07
the next AT Command.
1.5.3 Supported character sets
The A7600 Series AT Command interface defaults to the IRA character set. The A7600 Series supports the following character sets:
GSM format
UCS2
IRA
The character set can be set and interrogated using the "AT+CSCS" Command (3GPP TS 27.007). The character set is defined in GSM specification 3GPP TS 27.005.
The character set affects transmission and reception of SMS and SMS Cell Broadcast messages, the entry and display of phone book entries text field and SIM Application Toolkit alpha strings.

4.2.1 AT+CREG Network registration
This command is used to control the presentation of an unsolicited result code +CREG: <stat> when <n>=1 and there is a change in the ME network registration status, or code +CREG: <stat>[,<lac>,<ci>] when
<n>=2 and there is a change of the network cell.
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 ME. Location information elements <lac> and <ci> are returned only when <n>=2 and ME is registered in the network.

4.2.2 AT+COPS Operator selection
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.

4.2.4 AT+CSSN Supplementary service notifications
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 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.

6.2.7 AT+CRSM Restricted SIM access
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.

7.2.11 AT+CLIR Calling line identification restriction
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.

This command allows the control of the following call related services:
a call can be temporarily disconnected from the MT but the connection is retained by the network;
multiparty conversation (conference calls);
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 similarly as defined in 3GPP TS 22.030 [19].
This is based on the supplementary services HOLD (Call Hold; refer 3GPP TS 22.083 [5] clause 2 and
3GPP TS 24.610 [135]), MPTY / CONF (MultiParty; refer 3GPP TS 22.084 [22] and Conference; refer

10.2.11 AT+CURCD Configure the delay time and number of URC
This command is used to configure delay time when output URC and the number of cached URCs. You can control delay time if some URC supports delay output. You can also set size to store URCs, they will output together when the delay time ends. For Examples , if you set delay time to 10ms and set the number of cached URCs to 1, there is only one URC output after 10ms.

12.2 Detailed Description of AT Commands for File System
The file system is used to store files in a hierarchical (tree)structure, and there are some definitions and conventions to use the AT commands.
Local storage space is mapped to "C:", "D:" for SD card. ( The A7678 does not support SD card).
NOTE: General rules for naming (both directories and files): a) The length of actual fully qualified names of files(C:/)can not exceed 115.
b)The length of actual fully qualified names of directories and files(D:/)can not exceed 250.
c)Directory and file names can not include the following characters: \ / : * ? " < > | d)Between directory name and file/directory name, use character "/" as list separator, so it can not appear in directory name or file name.
e) File names on “C:/” drive cannot begin with “.” .
If the last character of names is period "."; the flash (C:/)will auto delete this character; the SD card can support this character, but the compatibility is not good.

The path of the file on EFS
The length of the file data to send.
Because of the system resources, The length could not set too large. If use the UART to send data, it may can set to 3Mb. If use USB to send data, it may just can set to 200Kb. If limit the send speed, it can set larger. The actual size could not ensure. Usually it is safer to set a smaller size.
The value is 100.
The position offset from the start of the file.
NOTE
1.The <filepath> must be a full path with the directory path, make sure that the file name does not exist under the path.
2.If sending file fails, increase the delay time between each 256 byte reach to 50ms, and then try to send file again.
3. Only Cat4 modules support Non-ASCII characters in file path.
4. The <reserved> is used by individual customers and if <location> is not default value,<reserved> will be considered invalid.
5.The <location> exceed the file size, the command will return “ ERROR ”.

Description
When client disconnect passively,
URC "+CMQTTCONNLOST" will be reported, then user need to connect
MQTT server again.
If a client subscribes to one or more topics, any message published to those topics are sent by the server to the client. The following URC is used for transmitting the message published from server to client.
1)+CMQTTRXSTART:
<client_index>,<topic_total_len>,<p ayload_total_len>\r\n
At the beginning of receiving published message, the module will report this to user, and indicate client index with <client_index>, the topic total length with
<topic_total_len> and the payload total length with
<payload_total_len> after "\r\n".
2)+CMQTTRXTOPIC:
<client_index>,<sub_topic_len>\r\n
<sub_topic>
After the command
"+CMQTTRXSTART" received, the module will report the second message to user, and indicate client index with <client_index>, the topic packet length with <sub_topic_len> and the topic content with
<sub_topic> after "\r\n".
For long topic, it will be split to multiple packets to report and the command "+CMQTTRXTOPIC" will be send more than once with the rest of topic content. The sum of
<sub_topic_len> is equal to
<topic_total_len>.
3)+CMQTTRXPAYLOAD:
<client_index>,<sub_payload_len>\ r\n<sub_payload>
After the command
"+CMQTTRXTOPIC" received, the
407 / 632
A76XX Series_AT Command Manual_V1.07
module will send third message to user, and indicate client index with
<client_index>, the payload packet length with <sub_payload_len> and the payload content with
<sub_payload> after "\r\n".
For long payload, the same as
"+CMQTTRXTOPIC".
4)+CMQTTRXEND: <client_index>
At last, the module will send fourth message to user and indicate the topic and payload have been transmitted completely.

24.2 Detailed Description of AT Commands for GNSS
24.2.1 AT+CGNSSPWR GNSS power control and AP-Flash control
In ASR1603 and ASR1803, this command can control the GNSS module by pulling up/down the power pin, and it can also control whether the GNSS module can quickly hot start the AP-Flash. If you only want to enable/disable GNSS control, please execute AT+CGNSSPWR=1 or AT+CGNSSPWR=0. If you want to enable GNSS and want to use AP_Flash fast hot start mode, please execute AT+CGNSSPWR=1,1 or www.simcom.com
461 / 632
A76XX Series_AT Command Manual_V1.07
AT+CGNSSPWR=0,1.
When using AP_Flash fast hot start mode, you need to execute AT+CGNSSPWR=0,1 to store the positioning data in the module after the GNSS is set to the upper position for the first time. When
AT+CGNSSPWR=1,1 is executed next time, the positioning data will be loaded into GNSS again.
.If you want to enable GNSS and want to use GNSS dynamic_load, please execute AT+CGNSSPWR=1,1,1 or AT+CGNSSPWR=1,0,1,The third parameter defaults to 1and it is optional
In ASR1601, this command can only control the GNSS module by pulling up/down the power pin.
