Smart Machine Smart Decision 1 Introduction E 1.1 Scope of the document FI L This document presents the AT Command Set for SIMCom SIM7000 Series, including SIM7000A, SIM700C and SIM7000E. You can visit the SIMCom Website using the following link: TI http://www.simcomm2m.com AL 1.2 Related documents EN 1.3 Conventions and abbreviations N FI D In this document, the GSM engines are referred to as following term: ME (Mobile Equipment); MS (Mobile Station); TA (Terminal Adapter); DCE (Data Communication Equipment) or facsimile DCE (FAX modem, FAX board); O M C O In application, controlling device controls the GSM engine by sending AT Command via its serial interface. The controlling device at the other end of the serial line is referred to as following term: TE (Terminal Equipment); DTE (Data Terminal Equipment) or plainly "the application" which is running on an embedded system; C 1.4 AT Command syntax SI M The "AT" or "at" or “aT” or “At”prefix must be set at the beginning of each Command line. To terminate a Command line enter . Commands are usually followed by a response that includes. " " Throughout this document, only the responses are presented, are omitted intentionally. The AT Command set implemented by SIM7000 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. SIM7000 Series_AT Command Manual_V1.02 11 2017-12-18 Smart Machine Smart Decision Note: Only enter AT Command through serial port after SIM7000 Series is powered on and Unsolicited Result Code "RDY" is received from serial port. If auto-bauding is enabled, the Unsolicited Result Codes "RDY" and so on are not indicated when you start up the ME, and the "AT" prefix, or "at" prefix must be set at the beginning of each command line. Basic syntax FI L 1.4.1 E All these AT commands can be split into three categories syntactically: "basic", "S parameter", and "extended". These are as follows: S Parameter syntax TI 1.4.2 AL These AT commands have the format of "AT ", or "AT& ", where " "is the Command, and " "is/are the argument(s) for that Command. An example of this is "ATE ", which tells the DCE whether received characters should be echoed back to the DTE according to the value of " ". " " is optional and a default will be used if missing. Extended Syntax D 1.4.3 EN These AT commands have the format of "ATS = ", where " " is the index of the S register to set, and " "is the value to assign to it. " " is optional; if it is missing, then a default value is assigned. FI These commands can operate in several modes, as in the following table: O N Table 1: Types of AT commands and responses M Read Command AT+ =? C Test Command O Write Command AT+ ? This command returns the currently set value of the parameter or parameters. AT+ =<…> This command sets the user-definable parameter values. AT+ The execution command reads non-variable parameters affected by internal processes in the GSM engine. M C Execution Command SI 1.4.4 The mobile equipment returns the list of parameters and value ranges set with the corresponding Write Command or by internal processes. 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 example: ATE1Q0S0=1S3=13V1X4;+IFC=0,0;+IPR=115200. SIM7000 Series_AT Command Manual_V1.02 12 2017-12-18 Smart Machine Smart Decision The Command line buffer can accept a maximum of 556 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". 1.4.5 Entering successive AT commands on separate lines FI L E When you need to enter a series of AT commands on separate lines, please Note that you need to wait the final response (for example OK, CME error, CMS error) of last AT Command you entered before you enter the next AT Command. 1.5 Supported character sets D EN TI AL The SIM7000 Series AT Command interface defaults to the IRA character set. The SIM7000 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. FI 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. O N 1.6 Flow control M C Flow control is very important for correct communication between the GSM engine and DTE. For in the case such as a data or fax call, the sending device is transferring data faster than the receiving side is ready to accept. When the receiving buffer reaches its capacity, the receiving device should be capable to cause the sending device to pause until it catches up. C O There are basically two approaches to achieve data flow control: software flow control and hardware flow control. SIM7000 Series support both two kinds of flow control. In Multiplex mode, it is recommended to use the hardware flow control. Software flow control (XON/XOFF flow control) M 1.6.1 SI Software flow control sends different characters to stop (XOFF, decimal 19) and resume (XON, decimal 17) data flow. It is quite useful in some applications that only use three wires on the serial interface. The default flow control approach of SIM7000 Series is hardware flow control (RTS/CTS flow control), to enable software flow control in the DTE interface and within GSM engine, type the following AT Command: AT+IFC=1, 1 SIM7000 Series_AT Command Manual_V1.02 13 2017-12-18 Smart Machine Smart Decision Ensure that any communications software package (e.g. Hyper terminal) uses software flow control. NOTE: Software Flow control should not be used for data calls where binary data will be transmitted or received (e.g. TCP/IP) as the DTE interface may interpret binary data as flow control characters. Hardware flow control (RTS/CTS flow control) E 1.6.2 AL FI L Hardware flow control achieves the data flow control by controlling the RTS/CTS line. When the data transfer should be suspended, the CTS line is set inactive until the transfer from the receiving buffer has completed. When the receiving buffer is ok to receive more data, CTS goes active once again. EN TI To achieve hardware flow control, ensure that the RTS/CTS lines are present on your application platform. 1.7 Definitions Parameter Saving Mode D 1.7.1 C O N FI For the purposes of the present document, the following syntactical definitions apply: 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. M 1.7.2 Max Response Time SI M C O Max response time is estimated maximum time to get response, the unit is seconds. "-" means this AT command doesn’t care the response time.
