1.5 AT command support

The SARA-R5 series modules support AT commands according to the 3GPP standards TS 27.007 [4],

TS 27.005 [5], TS 27.010 [6], and the u-blox AT commands extension.

☞ For the complete list of all supported AT commands and their syntax, see SARA-R5 series AT

commands manual [1].

1.6 Supported features

Table 3 lists some of the main features supported by SARA-R5 series modules. For more details, see

the SARA-R5 series system integration manual [2] and SARA-R5 series AT commands manual [1].

Feature

Description

Device security

An immutable chip ID and hardware-based 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: guarantees 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 hardware-backed 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)

 Local chip-to-chip (C2C) security: unique cryptographic pairing between the MCU of the

device and u-blox module by providing confidentiality, integrity, mutual authentication for

their communication channel (e.g. UART interface)

 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 costE2E data protection: encrypt data on a

device and decrypt asynchronously in cloud independent of protocols, servers, platforms or

time before reaching final destination



Access management

Allow only authenticated access to device and features, safely manage changes of device

ownership and provide out-of-the-box, simple, secure and cost effective zero touch onboarding

to popular IoT cloud platforms.

Access management features include:

 Change of ownership: efficient way to change the ownership and to apply the

policies / authorizations of the new owner, even if the device is already in the field

 Zero touch provisioning for AWS and Azure: out-of-the-box, simple, secure and cost effective

AWS and Azure onboarding

Integrated GNSS receiver 3 SARA-R510M8S modules are pre-integrated with a u-blox UBX-M8030 concurrent GNSS

chipset with SPG 3.01 firmware version, comprehensive of a dedicated GNSS antenna interface,

additional LNA and SAW filter for a highly reliable, accurate positioning data.

The GNSS system is totally independent from the LTE system and can run concurrently to a

LTE communication.

External GNSS control via

modem 4

Full access to external u-blox positioning chips and modules through DDC (I2C) interface.

This means that any host processor can control the SARA-R500S or SARA-R510S cellular

module and the u-blox positioning chip or module through a single serial port.

3 Not supported by SARA-R500S / SARA-R510S modules.

4 Not supported by SARA-R510M8S modules.
