THIS DOCUMENT IS A REFERENCE GUIDE TO ALL THE AT COMMANDS

1 Introduction

11 Scope of the document

This document presents the AT Command Set for SIMCom SIM8200ampSIM8300 Series

12 Related documents

You can visit the SIMCom Website using the following linkhttpwwwsimcomcom

13 Conventions and abbreviations

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)

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 term TE (Terminal Equipment) DTE (Data Terminal Equipment) or plainly the application which is running on an embedded system

14 AT Command syntax

wwwsimcomcom 17451

The AT or at or aT or At prefix must be set at the beginning of each Command line To terminate aCommand line enter ltCRgtCommands are usually followed by a response that includes ltCRgtltLFgtltresponsegtltCRgtltLFgtThroughout this document only the responses are presented ltCRgtltLFgt are omitted intentionally

The AT Command set implemented by SIM8200 Series is a combination of 3GPP TS 27005 3GPP TS27007 and ITU-T recommendation V25ter and the AT commands developed by SIMCom

Only enter AT Command through serial port after SIM8200 Series is powered on and Unsolicited ResultCode RDY is received from serial port If auto-bauding is enabled the Unsolicited Result CodesRDY and so on are not indicated when you start up the ME and the AT prefix orat prefix must beset 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 orATampltxgtltngt 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 ltmgtis 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 responsesTest CommandAT+ltxgt=

The mobile equipment returns the list of parameters and value ranges setwith the corresponding Write Command or by internal processes

wwwsimcomcom 18451

Read CommandAT+ltxgt

This command returns the currently set value of the parameter orparameters

Write CommandAT+ltxgt=lthellipgt

This command sets the user-definable parameter values

Execution CommandAT+ltxgt

The execution command reads non-variable parameters affected by internalprocesses in the GSM engine

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 AToratprefix before every command Instead you only need type ATorat 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

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 SIM8200 Series AT Command interface defaults to the IRA character set The SIM8200 Seriessupports the following character sets GSM format UCS2 IRAThe 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

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

wwwsimcomcom 19451

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 SIM8200 Series support both two kinds of flow controlIn Multiplex mode it is recommended to use the hardware flow control

161 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

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

wwwsimcomcom 20451

Max response time is estimated maximum time to get response the unit is seconds
