1 Introduction
11 Scope of the document
This document presents the AT Command Set for SIMCom SIM7500 and SIM7600 series
12 Related documents

13 Conventions and abbreviations
In this document the GSM engines are referred to as following termME (Mobile Equipment)MS (Mobile Station)TA (Terminal Adapter)DCE (Data Communication Equipment) or facsimile DCE (FAX modem FAX board)
In application controlling device controls the GSM engine by sending AT Command via its serial interfaceThe controlling device at the other end of the serial line is referred to as following termTE (Terminal Equipment)DTE (Data Terminal Equipment) or plainly the application which is running on an embedded system
14 AT Command syntax
The AT or at or aT or At prefix must be set at the beginning of each Command line To terminate aCommand line enter ltCRgt
SIM7500_SIM7600 Series_AT Command Manual_V200
wwwsimcomcom 17 460
Commands are usually followed by a response that includes ltCRgtltLFgtltresponsegtltCRgtltLFgtThroughout this document only the responses are presentedltCRgtltLFgt are omitted intentionally
The AT Command set implemented by SIM7500ampSIM7600 Series is a combination of 3GPP TS 270053GPP TS 27007 and ITU-T recommendation V25ter and the AT commands developed by SIMCom
Only enter AT Command through serial port after SIM7500ampSIM7600 Series is powered on andUnsolicited Result Code RDY is received from serial port If auto-bauding is enabled the UnsolicitedResult Codes RDY and so on are not indicated when you start up the ME and the AT prefix or atprefix must be set at the beginning of each command line
All these AT commands can be split into three categories syntactically basic S parameter andextended These are as follows
141 Basic syntax
These AT commands have the format of ATltxgtltngt or ATampltxgtltngt where ltxgtis the Command andltngtisare the argument(s) for that Command An example of this is ATEltngt which tells the DCEwhether received characters should be echoed back to the DTE according to the value of ltngt ltngt isoptional and a default will be used if missing
142 S Parameter syntax
These AT commands have the format of ATSltngt=ltmgt where ltngt is the index of the S register to setand ltmgt is the value to assign to it ltmgt is optional if it is missing then a default value is assigned
143 Extended Syntax
These commands can operate in several modes as in the following table
Table 1 Types of AT commands and responses
Test CommandThe mobile equipment returns the list of parameters and valueranges set with the corresponding Write Command or by internalprocesses
NOTE

AT+ltxgt=
Read CommandThis command returns the currently set value of the parameter orparameters
AT+ltxgtWrite Command This command sets the user-definable parameter valuesAT+ltxgt=lthellipgt
Execution CommandThe execution command reads non-variable parameters affectedby internal processes in the GSM engine
AT+ltxgt
144 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 atprefix before every command Instead you only need type AT or at the beginning of the command linePlease note to use a semicolon as the command delimiter after an extended command in basic syntax or Sparameter syntax the semicolon need not enter for exampleATE1Q0S0=1S3=13V1X4+IFC=00+IPR=115200
The Command line buffer can accept a maximum of 559 characters (counted from the first commandwithout AT or at prefix) or 39 AT commands If the characters entered exceeded this number then noneof the Command will executed and TA will return ERROR
145 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 thefinal response (for example OK CME error CMS error) of last AT Command you entered before you enterthe next AT Command
15 Supported character sets
The SIM7500ampSIM7600 Series AT Command interface defaults to the IRA character set TheSIM7500ampSIM7600 Series supports the following character setsGSM formatUCS2IRAThe character set can be set and interrogated using the AT+CSCS Command (3GPP TS 27007) Thecharacter set is defined in GSM specification 3GPP TS 27005
SIM7500_SIM7600 Series_AT Command Manual_V200
wwwsimcomcom 19 460
The character set affects transmission and reception of SMS and SMS Cell Broadcast messages the entryand display of phone book entries text field and SIM Application Toolkit alpha strings
16 Flow control
Flow control is very important for correct communication between the GSM engine and DTE For in thecase such as a data or fax call the sending device is transferring data faster than the receiving side is readyto accept When the receiving buffer reaches its capacity the receiving device should be capable to causethe sending device to pause until it catches up
There are basically two approaches to achieve data flow control software flow control and hardware flowcontrol SIM7500ampSIM7600 Series support both two kinds of flow controlIn Multiplex mode it is recommended to use the hardware flow control
161 Software flow control (XONXOFF flow control)
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 SIM7500ampSIM7600 Series is hardware flow control (RTSCTS flowcontrol) to enable software flow control in the DTE interface and within GSM engine type the following ATCommandAT+IFC=11
Ensure that any communications software package (eg Hyper terminal) uses software flow control
Software Flow control should not be used for data calls where binary data will be transmitted orreceived (eg TCPIP) as the DTE interface may interpret binary data as flow control characters
162 Hardware flow control (RTSCTS flow control)
Hardware flow control achieves the data flow control by controlling the RTSCTS line When the datatransfer should be suspended the CTS line is set inactive until the transfer from the receiving buffer hascompleted When the receiving buffer is ok to receive more data CTS goes active once again
NOTE
SIM7500_SIM7600 Series_AT Command Manual_V200
wwwsimcomcom 20 460
To achieve hardware flow control ensure that the RTSCTS lines are present on your application platform
17 Definitions
171 Parameter Saving Mode
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 doesnt have parameter AUTO_SAVE The parameter of the current AT command will be kept in NVRAM automatically and
take in effect immediately and it wont 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 wont be lost if module is rebooted
172 Max Response Time
Max response time is estimated maximum time to get response the unit is seconds
