1.15.8
HTTP
Embedded HTTP services are not supported by “00” and “50” product versions.
TOBY-L2 and MPCI-L2 series modules provide the embedded Hyper-Text Transfer Protocol (HTTP) services via AT
commands for sending requests to a remote HTTP server, receiving the server response and transparently storing
it in the module’s Flash File System (FFS).
For more details about embedded HTTP functionalities see the
u-blox AT Commands Manual
1.15.9
SSL
Embedded Transport Layer Security (TLS) / Secure Sockets Layer (SSL) protocols are not supported by the
“00”, “01” and “50” product versions.
TOBY-L2 and MPCI-L2 series modules provide the Transport Layer Security (TLS) / Secure Sockets Layer (SSL)
encryption protocols to enable security over the FTP and HTTP protocols via AT commands, implementing Secure
File Transfer Protocol (FTPS, i.e. FTP with TLS / SSL encryption) and Secure Hyper-Text Transfer Protocol (HTTPS,
i.e. HTTP with TLS / SSL encryption) services.
For more details about embedded TLS / SSL functionalities see the
u-blox AT Commands Manual
1.15.10
AssistNow clients and GNSS integration
AssistNow clients and u-blox GNSS receiver integration are not available on the MPCI-L2 series modules.
AssistNow clients and u-blox GNSS receiver integration are not supported by the TOBY-L2 series modules
“00”, “01” and “50” product versions.
For customers using u-blox GNSS receivers, TOBY-L2 series cellular modules feature embedded AssistNow clients.
AssistNow A-GPS provides better GNSS performance and faster Time-To-First-Fix. The clients can be enabled and
disabled with an AT command (see the
u-blox AT Commands Manual
TOBY-L2 series cellular modules act as a stand-alone AssistNow client, making AssistNow available with no
additional requirements for resources or software integration on an external host micro controller. Full access to
u-blox GNSS receivers is available via the TOBY-L2 series cellular module, through the DDC (I
2
C) interface, while
the available GPIOs can handle the positioning chipset / module power-on/off. This means that cellular module
and GNSS receiver can be controlled through a single serial port from any host processor.
1.15.11
Hybrid positioning and CellLocate
®
Hybrid positioning and CellLocate
®
are not available on MPCI-L2 series.
Hybrid positioning and CellLocate
®
are not supported by the TOBY-L2 series modules “00”, “01” and
“50” product versions.
Although GNSS is a widespread technology, its reliance on the visibility of extremely weak GNSS satellite signals
means that positioning is not always possible. Especially difficult environments for GNSS are indoors, in enclosed
or underground parking garages, as well as in urban canyons where GNSS signals are blocked or jammed by
multipath interference. The situation can be improved by augmenting GNSS receiver data with cellular network
information to provide positioning information even when GNSS reception is degraded or absent. This additional
information can benefit numerous applications.
