8 1. INTRODUCTION 1.1 SCOPE OF THE DOCUMENT This document presents the for the SAGEM SA MO 170 and MO 190 module. The MO 190 module supports all the MO 170 module AT commands plus the necessary commands to open voice communications link. In this present document, when a command is not supported by the MO 170 module, it is clearly noted in the related paragraph. The document will present the different AT command by category: Chapter 2: V25ter AT Commands Chapter 3: General AT Commands Chapter 4: Call Control Commands Chapter 5: Mobile equipment control and status Commands Chapter 6: Network service related Commands Chapter 7: Phone book management Chapter 8: SMS AT Commands Chapter 9: Data and FAX AT Commands Chapter 10: GPRS AT Commands Chapter 11: SIM Application Toolkit AT Commands Chapter 12: Audio Commands Each AT command is described and if necessary the standard reference is noted. (e.g.: ] 7.5). Some AT command are SAGEM SA proprietary: in this case it is clearly indicated. 1.2 SUPPORTED PRODUCT This specification concerns the MO 170 and MO 190 modules. Page 8 / 140

9 1.3 REFERENCE DOCUMENTS [04.08] GSM (6.7.1) Mobile radio interface layer 3 specification (Release 1997) [22.022] 3GPP (3.1.0) - Personalization of Mobile Equipment (ME); Mobile functionality specification (Release 1999) [27.005] 3GPP (5.0.0) Equipment (DTE - DCE) interface for Short Message Service (SMS) and Cell Broadcast Service (CBS) [27.007] 3GPP (6.0.0) - AT command set for User Equipment (UE) (Release 6) [V24] [V25ter] [STK] [SIM] Recommandation UIT-T V.24 - Liste des définitions des circuits de jonction entre l'équipement terminal de traitement de données et l'équipement de terminaison du circuit de données ITU-T Recommendation V.25 ter - Serial asynchronous automatic dialing and control Interface Requirements specification for AT Commands of the SIM Application Toolkit on MO190 Specification of the Subscriber Identity Module Mobile Equipment (SIM ME) interface. (GSM version Release 1999) 1.4 AT COMMAND PRINCIPLE The AT or at prefix must be set at the beginning of each line. To terminate a command line, a <CR> character must be inserted. Commands are usually followed by a response that includes <CR><LF><response><CR><LF>. Throughout this document, only the responses are indicated, the <CR> and <LF> characters are omitted intentionally. Comment: The TA can be setup to replace <CR> and <LF> with other characters (see ATS3 and ATS4 commands) Four kinds of AT commands are implemented: Test Command AT+CXXX=? The equipment returns the list of parameters and values ranges set with the with the corresponding or by internal processes. Read Command AT+CXXX? This command returns the currently set value of parameters. Write Command AT+CXXX=< > This command sets user-related parameter values. Execution command AT+CXXX The execution command reads nonvariable parameters affected by internal processes in the equipment. Page 9 / 140

10 1.4.1 In this document, the default parameters are underlined and the optional parameters are enclosed in square brackets. Optional parameters or sub-parameters can be omitted unless they are followed by other parameters. A parameter in the middle of a string can be omitted by replacing it with a comma. When the parameter is a character string, the string must be enclosed in quotation marks. All space characters will be ignored when using strings without quotation marks. It is possible to omit leading zeros of strings which represent numbers Possible Answers There is always an answer sent by the TA to an AT Command line (except the very special case of a TA setup for no answer, see ATQ). The answer is always terminated by an indication of success or failure. However, regarding the setup of the TA (by AT Commands), the message may be different. Classical messages: Extended Error message (see AT+CMEE) : or ERROR +CME ERROR: <n> (see Appendix for the different values for <n>) Numeric Mode (see ATV): <n> with: <n> = 0 or <n> is an error code Multiple AT Commands on the same command line You may enter several AT commands on the same line. This eliminates the need to type the "AT" or "at" prefix before each command and to wait for the answer for each command. The main advantage is to avoid loosing bandwidth on the link between DTE and the Module. There is no separator between two basic commands but a semi-colon character is necessary between two extended commands (prefix +). The command line buffer accepts a maximum of 391 characters. If this number is exceeded none of the commands will be executed and TA returns ERROR. If a command is not supported, then the treatment of the line is stopped (i.e. the following ones are not treated) and an error message is returned. Example: Command: Answer: ATZ&K3;+CBST=7,0,1;+CBST? +CBST=7,0,1 Page 10 / 140

11 1.4.4 AT Commands on separate lines When you enter a series of AT commands on separate lines, it is strongly advised to leave a pause between the preceding and the following command until the final answer ( or Error message) appears. This avoids sending too many AT commands at a time without waiting for a response for each. 1.5 MODIFICATION OF THIS DOCUMENT The commands described in this document are subject to change without notice, and shall only be used as a for usual AT commands use.

12 2. V25TER AT COMMANDS 2.1 A/ COMMAND: REPEAT PREVIOUS COMMAND LINE A/ Repeat previous command line Execute command A/ Depend on the previous command None V.25Ter Line does not need to end with terminating character COMMAND : SWITCH FROM DATA MODE TO COMMAND MODE +++ Switch from data mode to command mode Execute command +++ This command is only available during data calls. The +++ characters sequence causes to cancel de data flow over the AT interface and switch to command mode. This allows to enter AT commands while maintaining the data connection to the remote device. None V.25Ter To return to data mode, use the ATO command Line does not need to end with terminating character The + character may be changed with the ATS2 command (see following chapters) Page 12 / 140

13 2.3 O COMMAND : SWITCH FROM COMMAND MODE TO DATA MODE ATO Switch from command mode to data mode ATO[n] TA returns to data mode from command mode: CONNECT <text> If connection is not successfully resumed NO CARRIER Parameter <n> 0 switch from command mode to data mode GSM ATO is the alternative command to the +++ escape sequence described in Chapter 2.2: When you have established a data call and TA is in command mode, ATO causes the TA to resume the data connection and return to data mode. 2.4 E COMMAND : ENABLE COMMAND ECHO ATE Enable command echo Execute command ATE[<value>] <value> : 0 Echo mode off 1 Echo mode on V.25Ter This setting determines whether or not the TA echoes characters received from TE during command state Page 13 / 140

Information text transmitted in response is not affected by this setting. 2.6 S0 COMMAND : SET NUMBER OF RINGS BEFORE AUTOMATICALLY ANSWERING THE CALL ATS0 Set number of rings before automatically answering the call ATS0? <n> ATS0=<n> <n>: 0: automatic answering deactivated 1-255: number of rings before automatically answering V.25ter This command is valid only for data calls Page 14 / 140

16 2.9 S4 COMMAND : SET RESPONSE FORMATTING CHARACTER ATS4 Set response formatting character ATS4[<n>] <n> : response formatting character ATS4?

V.25Ter <n> This parameter determines the character recognized by TA to terminate an incoming command line (8 = <backspace> by default) Page 16 / 140
