This manual has a modular structure. It is not necessary to read it from the beginning to the end. The following symbols are used to highlight important information within the manual: An index finger points out key information pertaining to module integration and performance. A warning symbol indicates actions that could negatively impact or damage the module. Summary table The summary table on the top of each command section is a quick reference for the user. UBX-13002752 - R56 Preface Page 5 of 875 u-blox Cellular Modules - AT Commands Manual command_name Modules TOBY-L2 MPCI-L2 LISA-U110 LISA-U120 LISA-U130 LISA-U2 LEON-G1 SARA-G3 Attributes Syntax PIN required Settings saved full No No Can be aborted No Response time - Error reference - It is composed of two sections: • Modules: lists all the modules that support the command. The modules are grouped in rows by cellular standard (i.e. L for LTE high data rate (Cat 3 and above), R for LTE low data rate (Cat 1 and below), U for UMTS/ HSPA, G for GSM/GPRS). In each row the modules are grouped by: form factor (i.e. SARA, LISA), platform technology (e.g. SARA-G), platform generation (e.g. SARA-G3), product name (e.g. SARA-G350) and ordering code (e.g. SARA-G350-00S). In example: if 'LISA-U2' is reported, the command applies to all the modules having LISA form factor, second chipset version provided with any release of firmware. • Attributes o Syntax - full: the command syntax is fully compatible among all the products listed in the "Modules" section - partial: the products support different syntaxes (usually backward compatible with respect to previous cellular standards) o PIN required - Yes: it is necessary to insert the PIN before the set and/or read command execution - No: the PIN insertion is not needed to execute the command o Settings saved - Profile: the command setting can be saved in a personal profile as specified in Chapter 1.2 - NVM: the command setting is saved in the non-volatile memory as specified in Chapter 1.2 - No: the current command setting is volatile and cannot be saved o Can be aborted - Yes: the command execution can be aborted if a character is sent to the DCE during the command execution - No: the command cannot be aborted during the command execution o Response time: estimated maximum time to get the final result code for the AT command execution. More precisely, the command response time measures the time from the complete acquisition of the command line to the issuing of the command result code. This kind of response time is generally lower than the time measured by the application on the DTE, because the issuing of the command on the DTE is influenced by the AT interface characteristics (e.g. the synchronous/asynchronous transfer type, the selected baudrate, etc.), by power saving and flow control, which introduce a variable latency in the command acquisition by the DCE. For example, the maximum expected response time shall be extended if the communication with the module is carried out on a MUX virtual port, because in this case the command line and the result code are transferred via a specific protocol running on the physical port, that might introduce additional communication delay due to framing and retransmissions. Similarly, the maximum expected response time of AT commands accessing the SIM shall be extended if the module is using a remote SIM card via SAP instead of the local SIM card. If the response time for a command is left blank (actually "-"), it is an "immediate" response. It means that the command is executed without asynchronous requests to the protocol stack or the internal applications, which usually require time to be answered: the command execution is synchronous (implying that no long blocking processing is done) and lasts a negligible time (the command response is issued by the module in typically less than 10 ms, and in any case less than 1 s). The response time shall be extended if the issued AT command triggers a service that cannot be served immediately due to concurrent access to the same service or resource via AT commands issued on a different communication port or from internal applications; typical examples are registration commands UBX-13002752 - R56 Preface Page 6 of 875 u-blox Cellular Modules - AT Commands Manual and SIM access, that can be also autonomously triggered by the module (e.g. auto-COPS) and can therefore postpone the execution of the AT commands issued by the user. o Error reference: reference to the error result codes listed in the Appendix A u-blox Technical Documentation As part of our commitment to customer support, u-blox maintains an extensive volume of technical documentation for our products.

- AT Commands Manual 1 AT command settings u-blox cellular modules provide at least one physical serial interface, which is compliant to V.24ter [26]. At the module power on the module enters the command mode. For more details on command mode see the Chapter 1.1. For module and hyper terminal connection and settings see the corresponding evaluation kit user guide. 1.1 Definitions In this document the following naming conventions are used: • MT (Mobile Terminal) or DCE (Data Communications Equipment): u-blox cellular module • TE (Terminal Equipment) or DTE (Data Terminal Equipment): terminal that issues the command to the module • TA (Terminal Adaptor): the function, integrated in the MT, of supporting AT command interface according to the applicable standards • ME (Mobile Equipment): equivalent to MT, it is used to refer to the device itself regardless of the inserted SIM card The terms DCE and DTE are used in the serial interface context. TOBY-L4 / TOBY-L2 / MPCI-L2 / LARA-R2 / TOBY-R2 / SARA-U2 / LISA-U2 / LISA-U1 / SARA-G3 / LEON-G1 u-blox cellular modules can implement more than one interface between the DTE and the DCE, either virtual interfaces (multiplexer channels) or physical interfaces (UART, USB, SPI, etc., when available). Each interface works as specified by the followings definitions. If not differently stated, all the subsequent descriptions are applicable to each interface. Appendix B.5 describes the different behaviour among the interfaces in reference to the AT command interface. See the corresponding module data sheet for the list of available AT command interfaces. SARA-U201-04A / SARA-U201-04B / SARA-U201-04X / SARA-G340-02S / SARA-G340-02X / SARA-G350-02A / SARA-G350-02S / SARA-G350-02X Two UART AT interfaces can be used at the same time (it is not the default behaviour). See +USIO command description for details on how to set such behaviour. According to the terminology used in the data sheet, UART is the 9-wire asynchronous serial interface, while AUX UART is the 3-wire auxiliary asynchronous interface. The same naming will be used in the rest of the document (when not clearly specified, the description shall be considered applicable to both the interfaces). The DCE/MT interface can operate in these modes: • Command mode: the DCE waits for AT command instructions. The DCE interprets all the characters received as commands to execute. The DCE may send responses back to the DTE indicating the outcome of the command or further information without having received any commands by the DTE (e.g. unsolicited response code - URC). Any communication in the command mode (in both directions) is terminated by the command line termination character. • Data mode: the DCE transfers data after having sent the "CONNECT" string; all the characters sent to the DCE are intended to be transmitted to the remote party. Any further characters received over the serial link are deemed to be from the remote party, and any characters sent are transmitted to the remote party. The DCE enters data mode immediately after it makes a Circuit Switched Data (CSD) or Packet Switched Data (PSD) connection. • Online command mode: the DCE has a data connection established with a remote party, but treats signals from the DTE as command lines and sends back responses and unsolicited indications to the DTE. TOBY-L2 / MPCI-L2 / LARA-R2 / TOBY-R2 / SARA-U2 / LISA-U2 / LISA-U1 / SARA-G3 / LEON-G1 For more details on PSD connection see the +UPSD, +UPSDA and +UPSND commands description. SARA-G3 / LEON-G1 For more details on CSD connection see the +UCSD, +UCSDA and +UCSND commands description. UBX-13002752 - R56 1 AT command settings Page 21 of 875 u-blox Cellular Modules - AT Commands Manual SARA-U201-04A / SARA-U201-04B / SARA-U201-04X / SARA-G340-02S / SARA-G340-02X / SARA-G350-02A / SARA-G350-02S / SARA-G350-02X The AUX UART only supports the command mode. CSD or PSD connection are not allowed. TOBY-L4 The online command mode is not supported. 1.1.1 Switch from data mode to online command mode It is possible to switch from data mode to online command mode (when a data connection is established) in the following ways: • with the escape sequence: for more details see the S2 command description • via a DTR transition: during data mode, the current DTR state is not important, but only its transition. Furthermore, only the DTR transition from ON to OFF is detected; it can be used to control the switch to online command mode, or to command mode (the data connection is released). For more details see the Table 17 and the Table 18 To switch back to data mode from online command mode the O command is used. For more details see also the &D command. 1.1.2 Command description The AT commands configure and enable the cellular module functionalities according to 3GPP normative and u-blox specifications. The AT commands are issued to the module via a hyper terminal through a command line and are described in the following sections. A general description of each command is provided including the functionalities, the correct syntax to be provided by the TE/DTE, the allowed responses and an example. The command description defines each named parameter with its type, its range (valid / acceptable values), the default value (when available) and the factory-programmed value (when applicable). For default value it is intended the value automatically set if the parameter is omitted and at the module power-on (if the command setting is not stored in NVM/profile). For factory-programmed value it is intended the value set at the module power-on when the setting is not modified respect with the manufacturer setting; it is valid for the commands that store the setting in NVM/profile. The summary table on the top of each command section and the Appendix B lists all the u-blox cellular modules that support that command. The example provided in the command description refers only to the handling provided by the command. It may be not valid for all the products which the document is applied to. The list of allowed values for a specific product is provided in the corresponding "Defined values" section. In this documentare intentionally omitted in the command syntax. If a parameter is omitted, no value will be inserted between the two commas indicating the interested parameter in the command line sent by the DTE. 1.1.3 Default values If the command parameters are optional, they can be left out in the command line. If not otherwise specified, the default values are assumed as follows: • For parameters of type Number, the default value is 0 • For parameters of type String, the default value is an empty string 1.1.4 Command line The AT commands are typically issued to the cellular modules using a command line with the following generic syntax: "AT" Where: UBX-13002752 - R56 1 AT command settings Page 22 of 875 u-blox Cellular Modules - AT Commands Manual • "AT": prefix to be set at the beginning of each command line • : command name string; it can have a "+" character as prefix • : string consisting of the parameters value following the syntax provided in this manual The following rules are used when describing the command syntax: o <...>: the name in angle brackets is a parameter. The brackets themselves do not appear in the command line o [...]: the square brackets represent the optional parameters of a command or an optional part of the DCE information text response. Brackets themselves do not appear in the command line. When a parameter is not given, the value will be set to the default value provided in the command description Parameter types: o Number: positive and negative counting numbers, as well as zero {..., -2, -1, 0, 1, 2,...}. o String: sequence of characters enclosed within quotation marks (" "). • : command line termination character; the factory-programmed termination character is The maximum length of the command line is the maximum number of characters which can be accepted on a single command line (including the command line termination character). The command line is not case sensitive unless autobauding is enabled; in this case the prefix "AT" must be typed either as "AT" or "at"; other combinations ("aT" or "Ta") are not allowed. When writing or sending an SMS, Ctrl-Z or ESC terminates the command; is used between the two parts of the SMS (address and text). The serial interface driver generally does not allow a new command until the previous one has been terminated by "OK" final result code or by an error result code. In specific cases (see the abortability attribute), the command execution may be aborted if a character is sent to DCE before the command has ended. 1.1.4.1 Concatenation of AT commands TOBY-L4 It is not possible to concatenate the AT commands. More than one AT command can be entered on the same command line. The "AT" prefix must be provided only at the beginning of the command line. Each command must be separated by using a semicolon as delimiter only if the command has a "+" character as prefix. Example: ATI;+CGATT?;+COPS? If a command in the command line causes an error, or is not recognized as a valid command, then the execution is terminated, the remaining commands in the command line are ignored and an error result code is returned.

Command execution aborted issuing a character to the DCE Table 1: Allowed result codes LARA-R2 / TOBY-R2 In case of a VoLTE call redirected to CS plane the NO CARRIER final result code will be printed when the CSFB call is terminated from the remote part or the CSFB call establishment fails. In case of a VoLTE call experiencing entrance into out of coverage area, if service coverage cannot be regained within 10 s the call will be locally dropped and NO CARRIER will be printed; if the call is a VoLTE emergency call, NO CARRIER will not be printed and no local call release will be performed because the emergency call shall be maintained despite the speech interruption. TOBY-L2 / MPCI-L2 The AT commands can not be aborted, except if explicitly stated in the corresponding AT command description. LARA-R2 / TOBY-R2 / SARA-U2 / LISA-U2 / LISA-U1 When a command is aborted the ABORTED final result code (numeric result code: 18) is displayed. SARA-G3 / LEON-G1 When a command is aborted the OK result code (numeric result code: 0) is displayed. Intermediate outputs as well as descriptive outputs of a command are formatted as information text responses; if more than one string has to be printed out (see for example the +CGDCONT command description), additional command line termination and linefeed characters may be inserted for sake of readability. If the command is not accepted by the MT an error result code will be displayed. The AT+CMEE command configures the error result code format. In this manual it is assumed that AT+CMEE=2, which results in error result code of the format: • "+CMS ERROR: " for SMS-related AT commands • "+CME ERROR: " for any other AT commands where represents the verbose error result code. If AT+CMEE=1 command is issued, represents the numeric error result code. The most typical error result codes are the following: • If the command is not supported or unknown, either "+CME ERROR: unknown" or "+CME ERROR: operation not supported" is sent • If the command syntax is wrong, "+CME ERROR: operation not supported" is sent ("+CMS ERROR: operation not supported" for SMS related commands) TOBY-L2 / MPCI-L2 The AT command parser accepts optional commas at the end of the command line, as well as String parameters not delimited by "". The list of all the possible error result codes is available in Appendix A.1 and Appendix A.2. For some commands only the "ERROR" final result code is displayed and is documented in the command description. UBX-13002752 - R56 1 AT command settings Page 25 of 875 u-blox Cellular Modules - AT Commands Manual The proprietary AT commands supporting the following features implement a different error management and provide different error result codes: • Firmware update Over AT command and over the air: see the Appendix A.4 and Appendix A.5 • DNS: see the Appendix A.6 and Appendix A.7 • TCP and UDP connections, FTP, HTTP and SMTP: see the Appendix A.7, Appendix A.8, Appendix A.8.1, Appendix A.8.2, Appendix A.8.3 • IP change notification: see the Appendix A.9 • Ping: see the Appendix A.10 The corresponding sections provide more details for retrieving the error result codes for these operations. 1.2 Profiles Several user settings may be stored in the cellular module's memory. Some are directly stored in the non volatile memory (NVM), while the others are organized into two personal profiles. The first profile is the default profile, whose data is by default loaded during the module's power on. Appendix B.2 lists the complete settings that can be directly stored in NVM and the corresponding commands. Appendix B.1 lists the complete settings stored in the profiles and the corresponding commands. TOBY-L2 / MPCI-L2 / LARA-R2 / TOBY-R2 / SARA-U2 / LISA-U2 / LISA-U1 / SARA-G3 / LEON-G1 More details about loading, storing and updating profiles can be found in the command descriptions for: ATZ, AT&F, AT&W, AT&V, and AT&Y. TOBY-L4 The module does not store the AT commands setting in the profiles. 1.3 S-parameters The S-parameters, as specified in ITU-T recommendation V250 [20], constitute a group of commands that begin with the string "ATS". They are generally indicated as S registers and are used to configure the way the module operates. Their syntax is: ATS ? ATS = The number following the "ATS" is the referenced S parameter. u-blox cellular modules support the following set of S-parameters ( ): AT command S0 S2 S3 S4 S5 S6 S7 S8 S10 S12 S Number 0 2 3 4 5 6 7 8 10 12 Description Automatic answer setting Escape character setting Command line termination character setting Response formatting character setting Command line editing character setting Pause before blind dialling setting Connection completion timeout setting Command dial modifier time setting Automatic disconnect delay setting Escape prompt delay setting If a other than those listed above is introduced, the S command returns an error result code (+CME ERROR: operation not supported). UBX-13002752 - R56 1 AT command settings Page 26 of 875 u-blox Cellular Modules - AT Commands Manual 2 General operation 2.1 Start up and initialization The characteristics of the boot of the cellular device vary from module to module and are described in the corresponding System Integration Manual; during this phase the module might be not responsive on the AT interface until all necessary SW modules have been installed (e.g. USB drivers); monitoring of greeting text (see +CSGT command) where supported can help in detecting the successful end of the boot phase. TOBY-L4 After a successful boot and successful AT command interface initialization an +AT: READY URC is sent to the AT command interface. AT commands can be issued only after +AT: READY URC is received. A complete start up to be able to operate on the cellular network can take place only with a SIM card. If the SIM card has enabled the PIN check, some commands answer with "+CME ERROR: SIM PIN required" and most cellular functionalities are not started. After entering the required PIN via the +CPIN command, or if booting with a SIM with disabled PIN check, SIM initialization is carried out and a lot of SIM files are read: it is possible that some commands (e.g. phonebook AT commands) are affected by this preliminary phase, resulting in a temporary error response. 2.1.1 Auto-registration If the +COPS parameter in the profiles or in NVM is left to its factory-programmed value 0 or set to 1, after SIM initialization, all u-blox modules will automatically perform PLMN selection and registration for circuit switched/non EPS services as well as packet switched/EPS services. Auto-registration (sometimes called also "auto-COPS", not to be confused with automatic =0) will be triggered also at SIM insertion, for modules supporting SIM hot insertion, or at SIM driver recovery, occurring when the communication with the SIM card is re-established by the module after an unrecoverable error, caused e.g. by mechanical vibrations or electrical interference. If no SIM is inserted in the module, the module will anyway select a cell of the cellular network and try to maintain synchronization with it in limited service. The radio access technology selected by the module at start up is defined by the parameter of the +URAT command; afterwards the module will reselect the RAT based on the requirements of the cellular standards it complies with and it is not possible to force it to remain in a given RAT unless it is locked on it via +URAT or on a specific cell via +UCELLLOCK (if supported). The user can retrieve the result of the auto-registration by polling the registration status commands (e.g. +CREG/ +CGREG/+CEREG/+CIREG) or enabling their unsolicited notifications. If auto-COPS is running, at boot time or at SIM insertion, network service commands issued by the user might have a longer response time than expected; this is particularly visible when the module is switched on in a jammed condition, or with a roaming SIM card that shall perform several registration attempts before gaining access to a VPLMN. In case of failures of the automatic registration whose cause cannot be retrieved via +CEER, it is suggested to disable auto-COPS starting the module in +COPS:2 or in airplane mode +CFUN:4 and trigger registration with AT commands. 2.1.2 Operational restrictions Operational restrictions may derive from several settings: PIN required, SIM lock, invalidation of the IMEI or SIM credentials by the Mobile Network Operator (MNO) during the registration procedure, FDN enabled. Restrictions to access the network are applied by the module also in one of these conditions: • In eCall only state (for all modules supporting the eCall feature) • In minimum functionality power modes (+CFUN: 0, +CFUN: 4, +CFUN: 19, +CFUN: 127), and even if the module is restarted in +CFUN: 4 or +CFUN: 19 modes, because that are persistent • MPCI-L2 only - when the W_DISABLE# line is asserted • TOBY-L2 / SARA-U2 / LISA-U2 - The Radio Policy Manager has reached the maximum number of registrations or PDP contexts activation per hour (only with AT&T SIM cards [61]) UBX-13002752 - R56 2 General operation Page 27 of 875 u-blox Cellular Modules - AT Commands Manual In case the module is in operational restricted state, it may reject all or specific service requests (e.g. operator selection, connection establishment). MPCI-L2 When the W_DISABLE# line is asserted, to SW reset the module, AT+CFUN=0,1 or AT+CFUN=4,1 may be used as they refer to minimum functionality power modes. TOBY-L2 / MPCI-L2 If the SIM is not inserted or the PIN is required and not inserted, the network scan (+COPS=?) is not allowed. 2.2 AT commands types 2.2.1 Action command An action command forces the DCE to print information text or execute a specific action for the command. A typical example of this command type is the provision of the factory-programmed settings of the DCE like manufacturer name, firmware version, etc. 2.2.2 Set command A set command configures the preferred settings for the specified command. The set command is the only way to set the preferred settings in the DCE. For some commands it is possible to store the current settings in the profile or in the non volatile memory and retrieve them in another connection. TOBY-L2 / MPCI-L2 The set command without parameters (e.g. AT+CGEQREQ=) is syntactically equivalent to the action command (e.g. AT+CGEQREQ). 2.2.3 Read command A read command provides the current setting of the command parameters. It is used to find out the current command configuration. 2.2.4 Test command A test command provides the list of the values allowed by each parameter of the command. 2.2.5 Unsolicited Result Code (URC) An unsolicited result code is a string message (provided by the DCE) that is not triggered as a information text response to a previous AT command and can be output, when enabled, at any time to inform the DTE of a specific event or status change. The URC can have the same name of the command that enables it (e.g. +CREG) or can be enabled by another command (e.g. the +CMTI URC must be enabled by AT+CNMI AT command). 2.2.5.1 URCs presentation deferring Since the URCs are text responses issued by the DCE without being requested by the DTE, their occurrence is completely uncorrelated to an AT command execution. Therefore, a collision between a URC and an AT command response might occur and it may lead the DTE to misunderstand the URC as part of the AT command's text response or viceversa. The module avoids this collision by delaying the URCs presentation in case the AT command interface is busy. The AT command interface can be busy in the following cases: • During a data call (data mode) • During the execution of an AT command in command or online command mode The command execution starts when the command line is completed by the command line termination character and the AT interpreter in the module accepts it; the command execution ends when the final result code for the command is sent out. Inside this period, the module is not allowed to send the not buffered URCs. For most of the UBX-13002752 - R56 2 General operation Page 28 of 875 u-blox Cellular Modules - AT Commands Manual messages, the DCE needs to be configured whether or not to send a URC. After enabling, for most of the URCs, if the AT command interface is busy, the pending URCs are buffered and their sending to the DCE is deferred. The RING indication is always generated as an unsolicited result code. The NO CARRIER indication is generated as an unsolicited result code when it has not to be considered the final response for the executing command (e.g.: ATH); in case it is handled as an unsolicited result code, it follows the rule of the other URCs. Generally, the buffered URCs are sent to the terminal as soon as the terminal exits the data mode or the command execution is terminated. An exception to this behavior is implemented for the following URCs classes: Class Reception of a new SMS related URCs +CIEV URCs +CGEV URCs AT command to configure the class AT+CNMI AT command AT+CMER AT command AT+CGEREP AT command For the above classes, it is possible to select the presentation strategy in case of AT interface busy according the 3GPP TS 27.007 [2]; the buffering or discarding are the two possible choices (URCs are lost in the latter case). This is done by means of the corresponding AT command (see the AT command listed in the table above). If the URCs are enabled or for the three described classes of URCs, the buffered URCs are sent out only when the AT interface is in idle again; this occurs as soon as: • The data mode is released (the data call is disconnected) • The final result code for an AT command is issued LARA-R204 The presentation of +UCMT3GPP2 URCs is not deferred and is always routed to the AT interface. LEON-G1 The modules does not support the full URCs buffering/deferring capability: only the presentation deferring of the three above specified URCs classes is supported. The DTE should wait some time (the recommended value is at least 20 ms) after the reception of an AT command final result code or URC before issuing a new AT command to give the DCE the opportunity to transmit the buffered URCs. Otherwise the collision of the URCs with the subsequent AT command is still possible. In case multiple AT interfaces are available, it should be advisable to use one of the different AT interfaces to manage all the user enabled URCs, while use the others ones to send AT commands and receive their responses. Anyway URCs related to external causes (e.g. RING) are issued on all interfaces. 2.2.6 Intermediate Result Code (IRC) An intermediate result code is a string message (provided by the DCE) which provides to the DTE some information about the processing status of the pending AT command.

This mimics a silent reset and sets the module in a known initial state. Drivers and applications are not restarted, therefore if e.g audio was active, it might be negatively affected by the AT+CFUN=15 command. Additionally, most volatile parameters (e.g. URC) are lost and need to be reconfigured. TOBY-L2 / MPCI-L2 • After enabling the STK interface in raw mode it is not possible to switch to dedicated mode (and vice versa) without performing a reset. • =7 and 8 are not supported • =15 restarts the protocol stack tasks (without triggering a detach if the module is attached) while retaining the SIM status, i.e. the PIN shall not be inserted again. This mimics a silent reset and sets the module in a known initial state. Drivers and applications are not restarted, therefore if e.g. a MUX port was opened, communication with it is maintained, unless the AT+CFUN=15 interrupts a pending AT command requiring interaction with the protocol stack, in which case communication on MUX channels can be negatively affected. Additionally, most non-volatile parameters are not saved, as this kind of reset does not imply a complete module restart • parameter is ignored when entered after a not supporting reset. • In case the application needs to interact with the SIM, the AT+CFUN=1 command must be issued after the AT+CFUN=19 command.
