1.13.4
TCP/IP and UDP/IP
Not supported by SARA-G300 and SARA-G310 modules.
Via AT commands it is possible to access the embedded TCP/IP and UDP/IP stack functionalities over the Packet
Switched data connection. For more details about AT commands, see the
u-blox AT Commands Manual
Direct Link mode for TCP and UDP sockets is supported. 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. In
Direct Link mode, data sent to the serial interface from an external application processor is forwarded to the
network and vice-versa.
To avoid data loss while using Direct Link, enable HW flow control on the serial interface.
SARA-U2 modules product versions "x3" onward and SARA-G3 modules product versions "02" onward
support also Secure socket providing SSL encryption.

FTP
Not supported by SARA-G300 and SARA-G310 modules.
FTPS not supported by SARA-G3 modules "00" product versions.
SARA-G340, SARA-G350 and SARA-U2 series modules support the File Transfer Protocol functionalities via AT
commands. Files are read and stored in the local file system of the module.
SARA-U2 series modules support also Secure File Transfer Protocol functionalities providing SSL encryption.

as an HTTP client is implemented: HEAD, GET, POST, DELETE and PUT operations are available. The file size to be
uploaded / downloaded depends on the free space available in the local file system (FFS) at the moment of the
operation. Up to 4 HTTP client contexts can simultaneously be used.
SARA-U2 modules support also Secure Hyper-Text Transfer Protocol functionalities providing SSL encryption.
