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.
Capability to move between IPv4 and dual stack network infrastructures. IPv4 and IPv6
addresses can be used.
Full access to u-blox positioning chips and modules is available through a dedicated DDC
(I
2
C) interface. A single serial port from any host processor can control both the cellular
module and the positioning chips / modules.
For more details see the GNSS Implementation Application Note [3].
Embedded AssistNow Online and AssistNow Offline clients to provide full developed to
provide better GNSS performance and faster Time-to-First-Fix. The clients can be enabled /
disabled with an AT command.
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:
Normal scan: parameters of the visible home network cells are only sent
Deep scan: parameters of all surrounding cells of all mobile operators are sent
CellLocate
®
is implemented using a set of AT commands for CellLocate
®
service
configuration and position request.
Provides the module’s current position using a u-blox positioning chip or module 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.
Firmware update Over
AT commands (FOAT)
Firmware module upgrade over the UART interface using AT command.
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.
In-Band modem solution for eCall and ERA-GLONASS emergency call applications over
cellular networks implemented according to the 3GPP TS 26.267 specification [12].
When activated, the in-vehicle eCall / ERA-GLONASS system (IVS) creates an emergency
call carrying both voice and data (including vehicle position data) directly to the nearest
Public Safety Answering Point (PSAP) to determine whether rescue services should be
dispatched to the known position.
During a voice call, the Dual-Tone Multi-Frequency detector analyses the RX speech
(coming from remote party). The detected DTMF symbols can be output via related URC.
For more details, see the +UDTMFD AT command.
Automatic selection of
authentication type
9
Automatic selection of authentication type during PDP context activation. The module will
sequentially try different authentication protocols (none/CHAP/PAP) until the
authentication succeeds.
The feature can be enabled through the +UPSD and +UAUTHREQ AT commands.
Signal quality report
for PS calls
9
The quality of the GPRS UL and/or DL connection is returned by the AT+CSQ command.
When the Network Friendly Mode is enabled, the module reacts to service request denials
by using time-spaced, randomized or delayed retry schemes according to GSMA IoT
Device Connection Efficiency Guidelines [13].
The feature can be enabled through the +UNFM, +UNFMCONF, +URPM AT commands.
