Feature

Description

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 serial interface.

Embedded 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.

Embedded HTTP, HTTPS Hyper-Text Transfer Protocol as well as Secure Hyper-Text Transfer Protocol (SSL encryption)

functionalities are supported via AT commands.

CoAP (RFC 7252)

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

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

MQTT Anywhere and

MQTT Flex

Integrated MQTT-SN client for MQTT Anywhere IoT Communication-as-a-Service support in

combination with external Thingstream SIM, or for MQTT Flex IoT Communication-as-a-Service

support in combination with any external SIM

MQTT (v3.1.1) and

MQTT-SN (v1.2)

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

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.

TLS (v1.0, v1.1, v1.2, v1.3)

and DTLS (v1.2)

Transport Layer Security (TLS) provides security for HTTP, FTP, MQTT, and TCP communications.

Embedded Datagram Transport Layer Security (DTLS) provides security for LwM2M, and UDP

communications.

DNS

Support for DNS functionality.

IPv4/IPv6 dual-stack

Capability to move between IPv4 and dual stack network infrastructures. IPv4 and IPv6 addresses

can be used.

PPP

IPv4/IPv6 packets relaying through the cellular protocol stack performed on a Point-to-Point

Protocol (PPP) connection established with the external application via a serial interface.

Transitions between Online command mode (OLCM) and PPP mode are supported.

Multiple PDP contexts

Multiple PDP contexts can be activated, and multi secondary PDP contexts be associated to a

primary PDP context.

ODIS

Open mobile alliance device management IMEI Sync (ODIS) is an AT&T functionality required at the

cellular module level and used to identify the end device operating inside the network.

BIP

Bearer Independent Protocol (BIP) 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.

External u-blox GNSS

control via modem

Access to u-blox positioning chips and modules is available through a dedicated I2C interface.

This means that from any host processor, a single serial port can control the cellular module and

the u-blox positioning chip or module. For more details, see the GNSS application note [6].

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

A set of AT commands allows CellLocate® service configuration and position request.

☞ 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.

Hybrid positioning

The current module position is provided by a u-blox positioning chip or module or the estimated

position from CellLocate® depending on which method provides the best and fastest solution

according to the user configuration.

A set of AT commands allows Hybrid positioning service configuration and position request.
