TOBY-L2 and MPCI-L2 series - System Integration Manual
UBX-13004618 - R28
System description
Page 61 of 164
When Direct Link is used for a FTP file transfer, only the file content pass through USB / UART serial
interface, whereas all the FTP commands handling is managed internally by the FTP application.
For more details about embedded FTP functionalities see u-blox AT Commands Manual
1.15.8
HTTP
☞
Embedded HTTP services are not supported by “00” and “60” 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 / TLS
☞
Embedded Secure Sockets Layer (SSL) / Transport Layer Security (TLS) protocols are not
supported by the “00”, “01”, “60”, TOBY-L201-02S and MPCI-L201-02S product versions.
TOBY-L2 and MPCI-L2 series modules support the Secure Sockets Layer (SSL) / Transport Layer
Security (TLS) with certificate key sizes up to 4096 bits to provide security over the FTP and HTTP
protocols.
The SSL/TLS support provides different connection security aspects:
Server authentication: use of the server certificate verification against a specific trusted
certificate or a trusted certificates list
Client authentication: use of the client certificate and the corresponding private key
Data security and integrity: data encryption and Hash Message Authentication Code (HMAC)
generation
The security aspects used during a connection depend on the SSL/TLS configuration and features
supported. For a complete list of supported SSL/TLS configurations and settings see the u-blox AT

Bearer Independent Protocol
☞
BIP is not supported by the “00”, “60” product versions and by TOBY-L201-01S and MPCI-L201-01S
TOBY-L201-02S-00, MPCI-L201-02S-00 in AT&T configuration
The Bearer Independent Protocol (BIP) is a mechanism by which a cellular module provides a SIM with
access to the data bearers supported by the network. With the BIP for Over-the-Air SIM provisioning,
the data transfer from and to the SIM uses either an already active PDP context or a new PDP context
established with the APN provided by the SIM card. For more details, see the u-blox AT Commands

Wi-Fi integration
☞
u-blox short range communication Wi-Fi modules integration is not available for MPCI-L2 series
modules.
☞
u-blox short range communication Wi-Fi modules integration is not supported by the TOBY-L2
series modules “00”, “01” and “60” product versions.
Full access to u-blox short range communication Wi-Fi modules is available through a dedicated SDIO
interface (see sections
). This means that combining a TOBY-L2 series cellular module
with a u-blox short range communication module gives designers full access to the Wi-Fi module
