1.6 Supported features
Table 3 lists some of the main features supported by LARA-R2 modules. For more details, see
LARA-R2 series System Integration Manual [2] and u-blox AT Commands Manual [1].
Feature
Description
Network Indication
GPIO configured to indicate the network status: registered home network, registered roaming,
voice or data call enabled, no service. The feature can be enabled through the +UGPIOC AT
command.
Antenna Detection
The ANT_DET pin provides antenna presence detection capability, evaluating the resistance from
ANT1 and ANT2 pins to GND by means of an external antenna detection circuit implemented on
the application board.
The antenna detection feature can be enabled through the +UANTR AT command.
Jamming detection
9
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.
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.
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.
HTTP, HTTPS
Hyper-Text Transfer Protocol as well as Secure Hyper-Text Transfer Protocol
(SSL encryption)
functionalities are supported via AT commands. HEAD, GET, POST, DELETE and PUT operations
are available.
Embedded TLS 1.2
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.
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 connection established with the external application via a serial interface (UART, MUX, or
CDC-ACM). Transitions between Online command mode (OLCM) and PPP mode are supported.
BIP
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.
Multiple PDP contexts
Up to 8 PDP contexts can be activated, and multi secondary PDP contexts be associated to a
primary PDP context.
VoLTE
10
and CSFB
11
audio capability
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).
Firmware update Over AT
commands (FOAT)
Firmware module update over AT command interfaces.
The feature can be enabled and configured through the +UFWUPD AT command.
Firmware update Over
The Air (FOTA)
Embedded FOTA client to enable the Firmware module update over the cellular air interface.
The feature can be enabled and configured through the +UFWINSTALL AT command.
LTE / 3G Rx Diversity
Improved cellular link quality and reliability on all operating bands, by means of 2 receiving antenna
inputs.
GNSS via modem
12
Full access to u-blox positioning chips and modules is available through a dedicated DDC (I
2
C)
interface. This means that from any host processor, a single serial port can control the cellular
