1.14.4
Dual stack IPv4/IPv6
LARA-R2 series support both Internet Protocol version 4 and Internet Protocol version 6 in parallel.
For more details about dual stack IPv4/IPv6 see the
u-blox AT Commands Manual
1.14.5
TCP/IP and UDP/IP
LARA-R2 series modules provide embedded TCP/IP and UDP/IP protocol stack: a PDP context can be configured,
established and handled via the data connection management packet switched data commands.
LARA-R2 series modules provide Direct Link mode to establish a transparent end-to-end communication with an
already connected TCP or UDP socket via serial interfaces. In Direct Link mode, data sent to the serial interface
from an external application processor is forwarded to the network and vice-versa.
For more details about embedded TCP/IP and UDP/IP functionalities see the
u-blox AT Commands Manual
1.14.6
FTP
LARA-R2 series provide embedded File Transfer Protocol (FTP) services. Files are read and stored in the local file
system of the module.
FTP files can also be transferred using FTP Direct Link:
FTP download
: data coming from the FTP server is forwarded to the host processor via serial interfaces (for
FTP without Direct Link mode the data is always stored in the module’s Flash File System)
FTP upload
: data coming from the host processor via serial interfaces is forwarded to the FTP server (for FTP
without Direct Link mode the data is read from the module’s Flash File System)
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
1.14.7
HTTP
LARA-R2 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
