How to use this ManualThe u-blox Cellular Modules AT Commands Manual provides the necessary information to successfully designin and configure the applicable u-blox cellular modules.

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 tableThe summary table on the top of each command section is a quick reference for the user.

command_nameTOBY-L2 MPCI-L2

LISA-U110 LISA-U120 LISA-U130 LISA-U2

Modules

LEON-G1 SARA-G3

Syntax PIN required Settings saved Can be aborted Response time Error referenceAttributesfull No No No - -

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), Ufor UMTS/HSPA, G for GSM/GPRS, N for NB-IoT (LTE Cat NB1 / LTE Cat NB2)). In each row the modulesare 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 chipsetversion provided with any release of firmware.

• Attributeso 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- : the parameter values set with the command are volatile, but the whole profile

can be stored in NVM with AT command.- OP: the command setting can be overwritten by the Mobile Network Operator (MNO) profile set with

the +UMNOPROF AT command (if supported)- 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


UBX-13002752 - R66


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 thecommand line to the issuing of the command result code. This kind of response time is generally lowerthan the time measured by the application on the DTE, because the issuing of the command on theDTE 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 thecommand acquisition by the DCE.

For example, the maximum expected response time shall be extended if the communication with themodule is carried out on a MUX virtual port, because in this case the command line and the result codeare transferred via a specific protocol running on the physical port, that might introduce additionalcommunication delay due to framing and retransmissions.

Similarly, the maximum expected response time of AT commands accessing the SIM shall be extendedif 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 meansthat the command is executed without asynchronous requests to the protocol stack or the internalapplications, 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 responseis 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 servedimmediately due to concurrent access to the same service or resource via AT commands issued on adifferent communication port or from internal applications; typical examples are registration commandsand SIM access, that can be also autonomously triggered by the module (e.g. auto-COPS) and cantherefore 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

The attributes listed in the summary table apply by default to all u-blox modules supporting the specificAT command. If a u-blox module or module series does not comply to the default behavior, the exception ishighlighted in Chapter 1.2 for the saving of settings, in Chapter 1.1.6 for the abortability, and in a product specificnote in the AT command description for the PIN check.

u-blox Technical DocumentationAs part of our commitment to customer support, u-blox maintains an extensive volume of technicaldocumentation for our products. In addition to our product-specific technical data sheets, the followingmanuals are available to assist u-blox customers in product design and development.

AT Commands Manual: This document provides the description of the AT commands supported by u-bloxcellular modules.

System Integration Manual: This document describes u-blox cellular modules from the hardware and thesoftware point of view. It provides hardware design guidelines for the optimal integration of the cellular modulein the application device and it provides information on how to set up production and final product tests onapplication devices integrating the cellular module.

Application Notes: These documents provide guidelines and information on specific u-blox cellular modulehardware or software topics.• For some guidelines when developing applications for LTE Cat M1 technologies, see the SARA-R4 / SARA-N4

Application Development Guide [177].• For some guidelines when developing applications for NB-IoT technologies, see the NB-IoT Application

Development Guide [179].• For more examples of typical scenarios when developing application for LTE Cat 4, LTE Cat 1, UMTS/HSPA

and GSM/GPRS technologies, see the AT Commands Examples Application Note [175].See Related documents for application notes related to your cellular module.
