Software Version information can be retrieved by the command ATI. In this document, a short description, the syntax, the possible setting values and responses, and some examples of AT commands are presented. EN Prior to using the Module, please read this document and the Version History to know the difference from the previous document. References O 1.2 N FI D 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.

[…] underline E 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. Underlined defined subparameter value is the recommended default setting or factory setting. 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 and are intentionally omitted throughout this document. If command response is ERROR, not list the ERROR response inside command syntax. AL ♦ ♦ ♦ ♦ FI L 2.

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 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. N FI D 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 1. Basic Command O In the present document, AT commands are divided into three categories: Basic Command, S Parameter Command, and Extended Command. O M The format of Basic Command is “AT ” or “AT& ”, “ ” is the command name, and “ ” is/are the parameter(s) for the basic command, and optional. An example of Basic Command is “ATE ”, which informs the TA/DCE whether received characters should be echoed back to the TE/DTE according to the value of “ ”; “ ” 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 = ”, “ ” is the index of the S–register to set, and “ ” is the value to assign to it. “ ” is optional; in this case, the format is “ATS ”, and then a default value is assigned. 3. Extended Command The Extended Command has several formats, as following table list: SIM7500_SIM7600 Series_AT Command Manual_V1.03 18 2017-02-10 Smart Machine Smart Decision Table 2-1: Types of Extended Command Syntax Comments Test Command AT+ =? Test the existence of the command; give some information about the command subparameters. Read Command AT+ ? Check the current values of subparameters. Write Command AT+ =<…> Set user-definable subparameter values. Execution Command AT+ Read non-variable subparameters determined by internal processes. FI L E Command Type Information responses TI 2.3 AL NOTE: The character “+” between the prefix “AT” and command name may be replaced by other character. For example, using “#” or “$”instead of “+”. EN 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. SI M C O M C O N FI D Information responses start and end with , i.e. the format of information responses is “ ”. Inside information responses, there may be one or more .
