Description

Embedded AssistNow

Software

Embedded AssistNow Online and AssistNow Offline clients are available to provide better GNSS

performance and faster Time-to-First-Fix. An AT command can enable / disable the clients.

CellLocate®

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.

CellLocate® is available via a set of AT commands for CellLocate® service configuration and

position request.

Hybrid Positioning

Provides the module’s current position using a u-blox positioning chip or module (external for

SARA-R500S / SARA-R510S, integrated UBX-M8 chip for SARA-R510M8S) 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.

CellTime ™

Returns accurate timing retrieved from the LTE network and/or from the u-blox positioning chip

or module (external for SARA-R500S / SARA-R510S, integrated UBX-M8 chip for

SARA-R510M8S).

Can be used to provide periodic time-stamps to an external application processor or to output a

time indication associated to an interrupt detected on a GPIO (e.g. coming from an external

sensor connected to the module).

The implementation of CellTime ™ can be extended to control and maintain timing info in a

network of sensors (each one integrating a SARA-R5 module).

Antenna dynamic tuning

Control via two GPIOs an external antenna matching IC according to the LTE band used by the

module.

Embedded TCP and UDP

stack

Embedded TCP/IP and UDP/IP stack including direct link mode for TCP and UDP sockets.

Sockets can be set in Direct Link mode to establish a transparent end-to-end communication

with an already connected TCP or UDP socket via the serial interface.

HTTP, HTTPS

Hyper-Text Transfer Protocol as well as Secure Hyper-Text Transfer Protocol (SSL encryption)

functionalities are supported via AT commands.

FTP, FTPS

File Transfer Protocol as well as Secure File Transfer Protocol (SSL encryption of FTP control

channel) functionalities are supported by means of AT commands.

CoAP

Embedded Constrained Application Protocol (CoAP) datagram-based client/server application

protocol designed to easily translate from HTTP for simplified integration with the web.

MQTT and MQTT-SN

Embedded Message Queuing Telemetry Transport (MQTT) and MQTT for Sensor Networks

(MQTT-SN) publish-subscribe messaging protocols designed for lightweight M2M

communications over TCP (MQTT) or over UDP (MQTT-SN). These allow one-to-one, one-to-

many and many-to-one communications over a TCP or UDP connection.

LwM2M with dynamically

loaded objects

The LwM2M is a light and compact communication protocol designed for managing IoT

machine-to-machine communication between a LwM2M Server and a LwM2M Client located in

lightweight, low power or resource-constrained LwM2M devices, with object data model.

SARA-R5 series modules allow customers to configure dynamically loaded run time objects,

defining necessary custom objects, creating instances of those objects as appropriate,

managing module LwM2M protocol stack to interact with the LwM2M server.

TLS and DTLS

Transport Layer Security (TLS) version 1.2 provides security for HTTP, FTP, MQTT and TCP

communications.

Embedded Datagram Transport Layer Security (DTLS) version 1.2 provides security for CoAP,

LwM2M, MQTT-SN and UDP communications.

Jamming detection

Detects “artificial” interference that obscures the operator’s carrier entitled to give access to

the radio service and automatically reports the start and stop of such conditions to the

application processor that can react accordingly.

Last gasp

In case of power supply outage (i.e. main supply interruption, battery removal, battery voltage

below a certain threshold) the cellular module can be configured to send an alarm notification to

a remote entity. The feature can be enabled and configured through the +ULGASP AT

command.

Network status indication GPIO configured to indicate the network status: registered home network, registered roaming,

data call enabled, no service. The feature can be enabled through the +UGPIOC AT command.
