1.5 AT command support
The TOBY-R2 series modules support AT commands according to 3GPP standards TS 27.007 [8], TS 27.005 [9]
and the u-blox AT command extension.
For the complete list of all supported AT commands and their syntax, see the u-blox AT Commands
Manual [1].
RIL (Radio Interface Layer) software for Android and Embedded Windows is available for TOBY-R2 series modules
free of charge; see the Android RIL Production delivery [3] and Windows Embedded RIL Production delivery [4]
application notes for the supported software deliveries and more information.
1.6 Supported features
Table 3 lists some of the main features supported by TOBY-R2 modules. For more details see TOBY-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
6
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 via 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.
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 and CSFB
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/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.
6
Not supported by “02” product versions.
