Connect One Introduction
1 Introduction
1.1 General
Description
Nano WiReach
™
SMT is a secure serial-to-
Wireless-LAN device server module that also
acts as a bridge to connect serial devices to
802.11b/g Wireless LANs. It includes the
iChip
™
CO2144 IP Communication
Controller
™
chip and Marvell 88W8686 WiFi
chipset. It is packaged in RoHS-compliant
ultra-slim form factor and uses an industry
standard pin-out. The Nano WiReach SMT
can also be interfaced to a 10/100BaseT
wired LAN and a USB cellular modem with
some external components and glue logic.
Nano WiReach SMT offers much more than
many other device servers on the market. It
acts as a security gap between the application
and the network; supports up to 10
simultaneous TCP/UDP sockets; two listening
sockets; a web server with two websites;
SMTP and POP3 clients; MIME attachments;
FTP and TELNET clients, and SerialNET
™
mode for serial-to-IP bridging.
Nano WiReach SMT supports the SSL3/TLS1
protocol for secure sockets, HTTPS and
FTPS, WEP, WPA and WPA2 WiFi
encryption.
Nano WiReach SMT minimizes the need to
redesign the host device hardware. It features
a standard economical SMT footprint
providing for low-cost placement on a host
PCB with provisions for an on-board or
external antenna. Minimal or no software
configuration is needed for Nano WiReach
SMT to access the Wireless LAN.
Connect One’s high-level AT+i
™
API
eliminates the need to add WiFi drivers,
security and networking protocols and tasks to
the host application. The AT+i SerialNET
operating mode offers a true plug-and-play
mode that eliminates any changes to the host
application.
Nano WiReach SMT firmware – the IP stack
and Internet configuration parameters – are
stored in an external flash memory. The
module is power-efficient: the core operates at
1.2V, while I/Os operate at 3.3V. Power Save
mode further reduces power consumption.
The II-EVB-365SMT evaluation board
provides an easy environment for testing the
Nano WiReach SMT prior to designing it into
your product.
