1. Introduction

This manual is intended to familiarize customers with Connect One’s Instant Internet
Evaluation Board II-EVB-365SMT. The II-EVB-365SMT is an evaluation platform
for the Nano WiReach™ SMT Module, which is a secure serial-to-WiFi / serial-to­LAN module that provides a wide range of commands to initiate Internet connectivity
and can also act as a bridge to connect serial devices to wired Ethernet or 802.11b/g
wireless LANs. Furthermore, the module can also be configured as a full-blown router
between LAN and WiFi subnets. With an external USB modem communications and
routing are extended to the cellular network, providing for a unique mobile router
capability. The module has an economic SMT form factor and is based on
Connect One’s iChip CO2144 IP Communication Controller™ and the AT+i™
command set, a powerful set of Internet protocol commands developed by
Connect One to manage Internet connectivity through an Ethernet, Wireless LAN or
cellular connection.

The module enables sending and receiving textual and binary data, MIME-encoded
email messages; downloading HTML pages or files from a Web server, or items from
within a page; Web serving, as well as managing TCP or UDP socket
communications (with or without SSL3) over the Internet. It also include an FTP
client and a TELNET client.

Nano WiReach SMT can easily connect existing LAN based solutions to a WiFi
network when used in bridging mode.

Nano WiReach SMT supports numerous WiFi security protocols such as 64/128-bit
WEP encryption, AES-CCM and TKIP encryption, WPA (including AES) and WPA2
in both PSK and Enterprise modes. The module also supports the SSL3/TLS1 security
protocols.

When used as a router, the Nano WiReach SMT provides IP allocation via a DHCP
server and NAT translation when routing packets between a local subnet and a WAN.
Three-way routing between wired-LAN, WiFi and a cellular network is fully
supported. In routing mode, port-forward rules may be configured between the WAN
connection and any specific local subnet node.

2. Unpacking

Take the II-EVB-365 SMT out of its box. Included in the box are:

 The II-EVB-365 SMT motherboard incorporating the iW- SM2144SMT-OB

(Nano WiReach SMT module with On-board antenna).

 A serial cable with two DB-9 connectors
 A USB cable
 +9VDC Power supply adaptor (110/220 VAC)

3. Connections

1. Communications Cable:
 Serial RS232: Connect one end of the RS232 cable to the D-shell, 9-

pin female, Host RS232 port on the II-EVB-365 SMT (J5) and connect

the other DB-9 connector to the COM1 or COM2 serial port on your
PC, or to the serial port of your embedded device.

 USB: Connect one the device end of the USB cable to the EVB-365

SMT USB connector (J10) and connect the other end to a Host USB
port on your PC or embedded device.

2. Connect the II-EVB-365 SMT to the power supply.

4. Installing the iChipConfig Utility & Evaluation Software

II-EVB-365 SMT enables you to evaluate the Nano WiReach SMT module without
changing anything in your current development environment. Using a simple terminal
program on a PC, you can issue AT+i commands to the module and get responses.

AT+i commands are used to configure parameter values into iChip’s flash memory

and activate Internet tasks such as Email send/receive, socket manipulation, FTP
sessions, Web, and more.

A full description of the AT+i protocol can be found in the AT+i Programmer’s
Manual on the Connect One website at:

http://www.connectone.com/support.asp?did=42

To assist in configuring and evaluating the iChip, Connect One supplies the
iChipConfig Utility. This is a Windows-based GUI program that contains intuitive

dialog boxes to fully configure iChip. It doesn’t require any knowledge of AT+i

commands. In addition, it contains a local firmware upgrade function.

The iChipConfig Utility also allows you to perform specific Internet communication
tasks such as sending and receiving Emails, activating iChip’s websites, entering
SerialNET mode, and more.

For more information on the iChipConfig Utility and its usage, see the iChip Config
Utility User’s Manual.
. The latest iChipConfig Utility version and user manual can be found on the
Connect One website in the Support section at:

http://www.connectone.com/support.asp?did=30

Most frequently iChipConfig connects to the II-EVB-365 SMT though the PC’s
standard RS232 Serial port. A USB Device port is also available, which allows using
a USB connection as an alternative. To enable use of the PC USB port, a virtual COM
USB driver needs to be loaded on the PC. The iChipConfig can then be configured to
use the virtual port. Instructions for configuring the USB drivers on the PC are given
below in Appendix 2.

5. Testing the WiFi module Wireless Connection

To test the wireless LAN connection, you need to configure the Nano WiReach SMT
to connect to an Access Point:

1. Make sure an Access Point is connected and configured properly.

2. Start the iChipConfig Utility on your PC.

3. In the main window of the utility, click the Dumb Terminal icon.

4. In the Dumb Terminal window, enter the AT+i command to verify that the

iChip is communicating with your PC. You should receive an I/OK in
response. If this has failed, click the ―Setup Port‖ button and select the correct
COM port. When using a USB connection, select the USB virtual COM being
used.

5. Enter the AT+iRP11 command to obtain a report of all the Access Points

available in your area.

6. Enter AT+iWLSI=<ssid>. ssid is the ID of the Access Point you connect to.

Note that ssid is a case-sensitive string.

7. If you want to enable WEP encryption, configure the following parameters:

 AT+iWLWM=<n> where n=0 means no security, n=1 means 64-bit

key, and n=2 means 128-bit key

 AT+iWLKI=<n> where n is the WEP key index (n=1..4)
 AT+iWLK<n>=<keyString> where n is an index between 1 and 4, and

keyString is the WEP key string in the nth position.

8. If you want to enable WPA encryption, configure the following parameter:

AT+iWLPP=<passphrase> where passphrase is the pass-phrase to
be used in generating the WPA1-PSK encryption key. It is normal for the
iChip to take a few moments before returning I/OK in this case.

9. Enter AT+iDOWN in order to reset the module and connect to the WiFi

network.

At this stage a connection to the Access Point should be established. Verify that
the module has received an IP address from the DHCP server by issuing the
AT+iIPA? command. The module should reply with I/<IP address>.

To test the connection, use the iChipConfig utility to perform any activity that
requires network connection such as retrieving a web page, sending an email, or
opening a socket. You may also try to PING the iChip from another station on the
network.

6. Testing the Nano WiReach SMT Ethernet Connection

The II-EVB-365 SMT contains a standard 10/100BaseT RJ45 connector that allows a
direct connection to a wired LAN. To test the Ethernet LAN connection, you need to
configure the Nano WiReach SMT for your LAN:

1. Connect the module to the LAN network.

2. Start the iChipConfig Utility on your PC.

3. In the main window of the utility, click the Dumb Terminal icon.

4. In the Dumb Terminal window, enter the AT+i command to verify that the

iChip is communicating with your PC. You should receive an I/OK in
response. If this has failed, click the ―Setup Port‖ button and select the correct
COM port. When using a USB connection, select the USB virtual COM being
used.

5. Configure the module IP address in the +iDIP parameter. Set

AT+iDIP=0.0.0.0 if you want the module to receive IP settings for the
network’s DHCP server.

6. Set +iDIP to an IP address to skip the DHCP process and use a fixed IP. In this

case you should also define the +iSNET (subnet) parameter. For example,
AT+iSNET=255.255.255.0

7. Change the LAN type parameter to 2 (LAN) using the following command:

AT+iLTYP=2

8. Enter AT+iDOWN in order to reset the module and connect to the LAN

network.

To test the connection, use the iChipConfig utility to perform any activity that
requires network connection such as retrieving a web page, sending an email,
or opening a socket. You may also try to PING the iChip from another station
on the network.

9. Restore the LTYP parameter to zero to return to the default Wireless-LAN

operation.

7. Additional Connections

The modules support two additional connections:

SPI Slave

The modules support an alternative Host interface to the RS232 Serial port and the
USB connection. A host equipped with an SPI Master connection may connect to the
module’s SPI Slave port and interact with the module with AT+i commands.

An SPI cable (not supplied) connects to the II-EVB-365 SMT J2 SIP connector:
