SARA-G3 series - Data Sheet
UBX-13000993 - R20 Functional description
Page 9 of 47
Feature
Module
Description
Embedded TLS 1.2
7
SARA-G340 /
SARA-G350
With the support of X.509 certificates, Embedded TLS 1.2 provides server and client
authentication, data encryption, data signature and enables TCP/IP applications like HTTPS
and FTPS to communicate over a secured and trusted connection.
The feature can be configured and enabled by +USECMNG and +USECPRF AT commands.
IPv4/IPv6 dual-stack
9
SARA-G340 /
SARA-G350
Capability to move between IPv4 and dual stack network infrastructures. IPv4 and IPv6
addresses can be used.
GPS/GNSS via Modem
SARA-G340 /
SARA-G350
Full access to u-blox positioning chips and modules is available through a dedicated DDC
(I
2
C) interface. A single serial port from any host processor can control both the cellular
module and the positioning chips / modules.
For more details see the GNSS Implementation Application Note [3].
AssistNow Software
SARA-G340 /
SARA-G350
Embedded AssistNow Online and AssistNow Offline clients to provide full developed to
provide better GNSS performance and faster Time-to-First-Fix. The clients can be enabled /
disabled with an AT command.
CellLocate
®
SARA-G340 /
SARA-G350
Enables the estimation of device position based on the parameters of the mobile network
cells visible to the specific device based on the CellLocate
®
database:
Normal scan: parameters of the visible home network cells are only sent
Deep scan: parameters of all surrounding cells of all mobile operators are sent
CellLocate
®
is implemented using a set of AT commands for CellLocate
®
service
configuration and position request.
Hybrid Positioning
SARA-G340 /
SARA-G350
Provides the module’s current position using a u-blox positioning chip or module or the
estimated position from CellLocate
®
, depending on which positioning method provides the
best and fastest solution according to the user configuration.
Hybrid positioning is implemented through a set of AT commands that allow the
configuration and the position request.
Firmware update Over
AT commands (FOAT)
All
Firmware module upgrade over the UART interface using AT command.
BIP
9
SARA-G340 /
SARA-G350
Bearer Independent Protocol for Over-the-Air SIM provisioning. The data transfer to/from
the SIM uses either an already active PDP context or a new PDP context established with
the APN provided by the SIM card.
In-Band modem
SARA-G340 /
SARA-G350
In-Band modem solution for eCall and ERA-GLONASS emergency call applications over
cellular networks implemented according to the 3GPP TS 26.267 specification [12].
When activated, the in-vehicle eCall / ERA-GLONASS system (IVS) creates an emergency
call carrying both voice and data (including vehicle position data) directly to the nearest
Public Safety Answering Point (PSAP) to determine whether rescue services should be
dispatched to the known position.
DTMF decoder
SARA-G340 /
SARA-G350
During a voice call, the Dual-Tone Multi-Frequency detector analyses the RX speech
(coming from remote party). The detected DTMF symbols can be output via related URC.
For more details, see the +UDTMFD AT command.
Automatic selection of
authentication type
9
SARA-G340 /
SARA-G350
Automatic selection of authentication type during PDP context activation. The module will
sequentially try different authentication protocols (none/CHAP/PAP) until the
authentication succeeds.
The feature can be enabled through the +UPSD and +UAUTHREQ AT commands.
Signal quality report
for PS calls
9
SARA-G340 /
SARA-G350
The quality of the GPRS UL and/or DL connection is returned by the AT+CSQ command.
Network Friendly
Mode
9
SARA-G340 /
SARA-G350
When the Network Friendly Mode is enabled, the module reacts to service request denials
by using time-spaced, randomized or delayed retry schemes according to GSMA IoT
Device Connection Efficiency Guidelines [13].
The feature can be enabled through the +UNFM, +UNFMCONF, +URPM AT commands.
9
Supported by “02” product versions onwards

Feature
Module
Description
Smart Temperature
Supervisor
SARA-G340 /
SARA-G350
Constant monitoring of the module board temperature:
Warning notification when the temperature approaches an upper or lower
predefined threshold
Shutdown notified and forced when the temperature value is outside the specified
range (shutdown suspended in case of an emergency call in progress)
The Smart Temperature Supervisor feature can be enabled or disabled through an AT
command (see the u-blox AT commands manual [1], +USTS AT command)
The sensor measures board temperature inside the shields, which can differ from
ambient temperature.
Power saving
All
The power saving configuration is by default disabled, but it can be configured using an
AT command. When power saving is enabled, the module automatically enters the low
power idle-mode whenever possible, reducing current consumption.
During idle-mode, the module processor core runs with the RTC 32 kHz reference clock,
which is generated by:
The internal 32 kHz oscillator, in case of SARA-G340 and SARA-G350 modules
The 32 kHz signal provided at the EXT32K input pin, in case of SARA-G300 and
SARA-G310 modules
For more details, see the SARA-G3 / SARA-U2 Series System Integration Manual [2] and
the u-blox AT commands manual [1], +UPSV AT command.
Table 4: SARA-G3 series’ main supported features
u-blox is extremely mindful of user privacy. When a position is sent to the CellLocate
®
server, u-blox is
unable to track the SIM used or the specific device.
