1.5 AT command support

The LARA-R6 series modules support AT commands according to 3GPP standards TS 27.007 [7],

TS 27.005 [8] and the u-blox AT command extension.

☞ For a complete list of supported AT commands, see the AT commands manual [1].

RIL (Radio Interface Layer) software for Android is available free of charge; see the Android RIL source

code application note [3] for the supported software deliveries and more information.

1.6 Supported features

Table 4 lists some of the main features supported by LARA-R6 series modules. For more details, see

the AT commands manual [1] and the application development guide [5].

Feature

Description

Device security

An immutable chip ID and Root of Trust (RoT) embedded in a dedicated Common Criteria EAL5+

high certified secure element provide foundational security and a unique device identity.

Device security features include:

• Secure boot: software authenticity and integrity

• Secure update: secure delivery of the correct FW to the module

• Anticloning detection and rejection: system automatically identifies and blocks clones that use

the same RoT

Data security

Secure libraries allow generation of crypto functions and keys for local encryption to secure local

file storage and for end-to-end encryption.

Data security features include:

• Local data protection: symmetric crypto functions via AT command to locally encrypt / decrypt

and authenticate data (e.g., certificates, tokens) on the device. Allows also secure local storage

of sensitive information in a non-secure location (e.g., in “standard” device memory)

• E2E symmetric KMS: highly scalable method to provision and manage a session unique PSK

available in cloud via REST API. Up to 8 times reduction in secure communication data overhead

reducing data power consumption and cost

• E2E data protection: encrypt data on a device and decrypt asynchronously in cloud independent

of protocols, servers, platforms, or time before reaching final destination

u-blox Firmware update

Over The Air (uFOTA)

u-blox firmware module update over the air interface client/server solution using LwM2M.

Firmware update Over AT

commands (FOAT)

Firmware module update over AT command interfaces.

VoLTE and CSFB audio

capability 3

Voice over LTE (VoLTE) feature allows voice service over LTE bearer, via embedded IP Multimedia

Subsystem (IMS).

Circuit Switched Fall-Back (CSFB) feature allows voice service over circuit switched infrastructure

(3G or 2G radio access technologies, which are not supported by LARA-R6401 modules).

LTE / 3G Rx Diversity

Improved cellular link quality and reliability on all operating bands, by means of 2 receiving antenna.

Network indication

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

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

Antenna detection

The ANT_DET pin provides antenna presence detection capability, as optional features, evaluating

the resistance from ANT1 and ANT2 pins to GND by means of an external antenna detection

circuit implemented on the application board.

Antenna dynamic tuning 4 Control of an external antenna matching IC via two GPIOs changing dynamically the high/low state

in real time according to the cellular band used by the module.

Jamming detection

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

radio service and reports the start and stop of such conditions to the application processor that

can react accordingly.
