About the document This document is to describe all AT commands implemented on the Telit wireless modules listed on the Applicabilty Table.

80446ST10707A Rev. 0– 2015-11-03 Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 18 of 509 Mod. 0808 2011-07 Rev.2 AT COMMANDS The Telit wireless module family can be controlled via the serial interface using the standard AT commands 1. The Telit wireless module family is compliant with: 1. Hayes standard AT command set, in order to maintain the compatibility with existing SW programs. 2. 3GPP TS 27.007 specific AT command and GPRS specific commands. 3. 3GPP TS 27.005 specific AT commands for SMS (Short Message Service) and CBS (Cell Broadcast Service) Moreover Telit wireless module family supports also Telit proprietary AT commands for special purposes. The following is a description of how to use the AT commands with the Telit wireless module family. 3.1. Definitions The following syntactical definitions apply: Carriage return character, is the command line and result code terminator character, which value, in decimal ASCII between 0 and 255,is specified within parameter S3. The default value is 13. Linefeed character, is the character recognised as line feed character. Its value, in decimal ASCII between 0 and 255, is specified within parameter S4. The default value is 10. The line feed character is output after carriage return character if verbose result codes are used (V1 option used ) otherwise, if numeric format result codes are used (V0 option used) it will not appear in the result codes. <...> Name enclosed in angle brackets is a syntactical element. They do not appear in the command line. [...] Optional subparameter of a command or an optional part of TA information response is enclosed in square brackets. Brackets themselves do not appear in the command line. When subparameter is not given in AT commands which have a Read command, new value equals to its previous value. In AT commands which do not store the values of any of their subparameters, and so have not a Read command, which are called action type commands, action should be done on the basis of the recommended default setting of the subparameter. 1 The AT is an ATTENTION command and is used as a prefix to other parameters in a string. The AT command combined with other parameters can be set up in the communications package or typed in manually as a command line instruction.combined with other parameters can be set up in the communications package or typed in manually as a command line instruction.

AT Command Syntax The syntax rules followed by Telit implementation of either Hayes AT commands, GSM commands are very similar to those of standard basic and extended AT commands There are two types of extended command: - Parameter type commands. This type of commands may be “set” (to store a value or values for later use), “read” (to determine the current value or values stored), or “tested” (to determine ranges of values supported). Each of them has a test command (trailing =?) to give information about the type of its subparameters; they also have a Read command (trailing ?) to check the current values of subparameters. - Action type commands. This type of command may be “executed” or “tested”. • “executed“ to invoke a particular function of the equipment, which generally involves more than the simple storage of a value for later use • “tested” to determine: if subparameters are associated with the action, the ranges of subparameters values that are supported; if the command has no subparameters, issuing the correspondent Test command (trailing =?) raises the result code “ERROR”. Note: issuing the Read command (trailing ?) causes the command to be executed. whether or not the equipment implements the Action Command (in this case issuing the correspondent Test command - trailing =? - returns the OK result code), and, if subparameters are associated with the action, the ranges of subparameters values that are supported. Action commands don’t store the values of any of their possible subparameters. Moreover: The response to the Test Command (trailing =?) may be changed in the future by Telit to allow the description of new values/functionalities. If all the subparameters of a parameter type command +CMD are optional, issuing AT+CMD= causes the OK result code to be returned and the previous values of the omitted subparameters to beretained. 3.2.1.

According to V25.ter space characters are ignored on the command line and may be used freely for formatting purposes, unless they are embedded in numeric or quoted string constants; therefore a string containing a space character has to be enclosed between quotes to be considered a valid string type parameter (e.g. typing AT+COPS=1,0,”A1” is the same as typing AT+COPS=1,0,A1; typing AT+COPS=1,0,”A BB” is different from typing AT+COPS=1,0,A BB). A string is always case sensitive. A small set of commands requires always to write the input string parameters within quotes: this is explicitly reported in the specific descriptions. 3.2.2. Command Lines A command line is made up of three elements: the prefix, the body and the termination character. The command line prefix consists of the characters “AT” or “at”, or, to repeat the execution of the previous command line, the characters “A/” or “a/” or AT#/ or at#/. The termination character may be selected by a user option (parameter S3), the default being . The basic structures of the command line are: • ATCMD1 where AT is the command line prefix, CMD1 is the body of a basic command (nb: the name of the command never begins with the character “+”) and is the command line terminator character • ATCMD2=10 where 10 is a subparameter • AT+CMD1;+CMD2=, ,10 These are two examples of extended commands (nb: the name of the command always begins with the character “+” 2). They are delimited with semicolon. In the second command the subparameter is omitted. • +CMD1? This is a Read command for checking current subparameter values • +CMD1=? This is a test command for checking possible subparameter values These commands might be performed in a single command line as shown below: ATCMD1 CMD2=10+CMD1;+CMD2=, ,10;+CMD1?;+CMD1=? anyway it is always preferable to separate into different command lines the basic commands and the extended commands; furthermore it is suggested to avoid placing several action commands in 2 The set of proprietary AT commands differentiates from the standard one because the name of each of them begins with either “@”, “#”, “$” or “*”. Proprietary AT commands follow the same syntax rules as extended commands

If command V1 is enabled (verbose responses codes) and all commands in a command line has been performed successfully, result code OK is sent from the TA to the TE, if subparameter values of a command are not accepted by the TA or command itself is invalid, or command cannot be performed for some reason, result code ERROR is sent and no subsequent commands in the command line are processed. If command V0 is enabled (numeric responses codes), and all commands in a command line has been performed successfully, result code 0 is sent from the TA to the TE, if sub-parameter values of a command are not accepted by the TA or command itself is invalid, or command cannot be performed for some reason, result code 4 and no subsequent commands in the command line are processed. In case of errors depending on ME operation, ERROR (or 4) response may be replaced by +CME ERROR: or +CMS ERROR: . NOTE: The command line buffer accepts a maximum of 400 characters. If this number is exceeded none of the commands will be executed and TA returns ERROR. 3.2.2.1.

Command Response Time-Out Every command issued to the Telit modules returns a result response, if response codes are enabled (default). The time needed to process the given command and return the response varies, depending on the command type. Commands that do not interact with the SIM or the network, and only involve internal setups or readings, have an immediate response.Commands that interact with the SIM or the network could take many seconds to send a response, depending on SIM configuration (e.g., number of contacts stored in the phonebook, number of stored SMS), or on the network the command may interact with. 3.2.5. Command Issuing Timing The chain Command -> Response shall always be respected and a new command must not be issued before the module has terminated all the sending of its response result code (whatever it may be). This applies especially to applications that “sense” the OK text and therefore may send the next command before the complete code OK is sent by the module. It is advisable anyway to wait for at least 20ms between the end of the reception of the response and the issue of the next AT command. If the response codes are disabled and therefore the module does not report any response to the command, then at least the 20ms pause time shall be respected. 3.3. Storage 3.3.1. Factory Profile And User Profiles The Telit wireless modules stores the values set by several commands in the internal non volatile memory (NVM), allowing to remember this setting even after power off. In the NVM these values are set either as factory profile or as user profiles: there are two customizable user profiles and one factory profile in the NVM of the device: by default the device will start with user profile 0 equal to factory profile. For backward compatibility each profile is divided into two sections, one base section which was historically the one that was saved and restored in early releases of code, and the extended section which includes all the remaining values. The &W command is used to save the actual values of both sections of profiles into the NVM user profile. Commands &Y and &P are both used to set the profile to be loaded at startup. &Y instructs the device to load at startup only the base section. &P instructs the device to load at startup the full profile: base + extended sections. The &F command resets to factory profile values only the command of the base section of profile, while the &F1 resets to factory profile values the full set of base + extended section commands.

The values set by following commands are stored in the profile base section; they depend on the specific AT instance: DTE SPEED +IPR COMMAND ECHO E RESULT MESSAGES Q VERBOSE MESSAGES V EXTENDED MESSAGES X POWER SAVING +CFUN (it does not depend on the specific AT instance) DEFAULT PROFILE &Y S REGISTERS S0;S2;S3;S4;S5;S7;S10;S12;S25 The values set by following commands are stored in the profile extended section and they depend on the specific AT instance (see +CMUX): +FCLASS +CSCS +CR +CREG +CLIP +CRLP +CRC +CLIR +CSVM +CCWA +CUSD +CAOC +CSSN +CIND +CMER +CPBS +CMEE +CGREG +CGEREP +CMGF +CSDH +CNMI #QSS #ECAM #SMOV #MWI #NITZ #SKIPESC #CFF #STIA +CSTF +CSDF +CTZU +CAPD +CCWE +CSIL +CTZR #NWEN #PSNT #SIMPR +COLP #CESTHLCK $GPSNUM +CSTA +NCIH The values set by following commands are stored in the profile extended section and they don’t depend on the specific AT instance (see +CMUX): +CALM +CRSL +CMUT

If A/ is issued before any command line has been executed, the preceding command line is assumed to have been empty (that results in an OK result code). Note: this command works only at fixed IPR. Note: the custom prefix AT#/ has been defined: it causes the last command to be executed again too; but it doesn’t need a fixed IPR.
