1 Introduction
1.1 General Description
WiReach BK 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.
WiReach BK 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.
WiReach BK supports the SSL3/TLS1
protocol for secure sockets, HTTPS and
FTPS, WEP, WPA and WPA2 WiFi
encryption.
WiReach BK minimizes the need to
redesign the host device hardware. It
easily inserts into headers on the host
PCB and connects to an external
antenna. Minimal or no software
configuration is needed for WiReach BK
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.
WiReach BK 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.
