1Introduction
The family of AMWx06 ‘Numbat’ modules are fully certified small form factor, low power Wi-Fi networking modules
perfectly suited to deeply embedded applications requiring medium/high data throughput in medium to high
volume.
The Sensors.com WiConnect Operating System is pre-installed on all AMWx06 modules. WiConnect provides
products with an intuitive, reliable and secure Wi-Fi networking connection featuring an embedded TCP/IP
networking stack that includes a webserver with REST & websockets, a fully customizable javascript-based web
application and SSL/TLS security.
Evaluation of WiConnect and the AMWx06 module is available with the AMW106-E03 ‘Moray’ evaluation board. The
evaluation board is shown in Figure 1 and its features are shown in Table 1.
This document describes how to use the Moray evaluation board populated with an AMW106 module, usage is
however identical whether the board is populated with an AMW006 module or an AMW106 module.

By removing all jumpers from the GPIO isolation header, all peripherals may be completely disconnected from
module GPIOs. This provides several benefits including the option to connect custom peripherals without
interference from on-board peripherals, and simplification of power consumption measurements described in the
Measuring Power Usage section.

3Using WiConnect
To get started with WiConnect, plug the AMW106 evaluation board into the USB port of the computer and open a
terminal emulator as described in Appendix A. The USB cable provides the evaluation board with power and a serial
UART connection to the computer.
With the board connected to the computer, verify the power LED is illuminated. If the power LED is NOT illuminated,
try re-plugging the USB cable, or try a different USB cable.
Note! Be sure to use a quality USB cable. Inferior cables may result in reduced or intermittent operation
of the evaluation board.
3.1 Getting Help
WiConnect provides extensive help for each command and variable. To obtain a list of help options, type the help
command.
> help
The following help options are available ...
help all -> Print a list of all Commands and Variables
help commands -> Print a list of Commands
help variables -> Print a list of Variables
help <command> -> Print help for a specific Command
help <variable> -> Print help for a specific Variable
Additional help is available online at http://wiconnect.ack.me
To obtain help for a particular command or variable, type help <command> or help <variable>.
To obtain help for the wlan_scan variable, type help wlan_scan.
> help wlan_scan
Usage : wlan_scan [-v] [<channel> [ssid]]
Shortcut: scan
Brief : Initiate a Wi-Fi scan and return results; optionally specify
a channel and AP SSID to scan for. For verbose scans, -v must be the first argument

3.2 System Indicator LEDs
The Moray evaluation board comes with three system indicator LEDs and two user LEDs. The LED functions are
configurable, using the WiConnect peripheral commands and variables. See http://wiconnect.ack.me for more
details., in particular the variables system.indicator.gpio and system.indicator.state.
By default the system indicator LEDs are configured as follows:

3.3 Scanning for Wi-Fi Networks
To scan for Wi-Fi networks in range, use the wlan_scan command. Each AP in range is listed on a separate line.
> wlan_scan -v

3.4 Joining a Wi-Fi Network
Several methods are available to configure and join the AMW106 module to a Wi-Fi network.
Web Setup
WiConnect provides the option to use a web browser running on a network client (such as a smartphone, tablet or
computer) to select the remote Wi-Fi network the AMW106 module should join, and to enter a password for the
remote network.
When web setup is used, it is helpful to think of the network client as the keyboard and display for the module as
shown in Figure 3.

Figure 3. Web setup using a network client
To start web setup mode, enter the command setup web. WiConnect starts the local network and web server as
indicated by the final message: In progress.
> setup web
[Disassociated]
IPv4 address: 10.10.10.1
Web setup started with the SSID: WiConnect-F1A
In progress
Open the Wi-Fi settings on your smartphone, tablet or computer and join the network called WiConnect-###
(where ### are the last 3 digits of the Wi-Fi module MAC address). The password for the network is simply:
password. The local network name and password, and the web address may be customised to suit your needs, see
the online WiConnect Reference Manual for further information.
After joining the local network, open a web browser on the network client and go to setup.com. The WiConnect web
page appears (see Figure 3), and a scan begins for Wi-Fi access points in range. Select the remote network you wish
to join, enter the network password then select Save & Exit and follow the prompts.
Once the settings are successfully saved, WiConnect prints Web Setup Mode exited to the terminal. Check that
the settings were successfully saved using get wlan.ssid and get wlan.passkey.
Web Setup Mode exited
> get wlan.ssid
YOUR_NETWORK_NAME
> get wlan.passkey
YOUR_NETWORK_PASSWORD
Script Setup
If you prefer instead to enter configuration details for the Wi-Fi network, WiConnect provides a default setup script
to step you through the process. The setup script is provided as a file called default_setup.script on the
WiConnect file system. The setup script may be customised as required.
> setup cmd
> Enter Wi-Fi network name:
set wlan.ssid YOUR_NETWORK_NAME
Set OK
Remote Network
Name: YOUR_NETWORK_NAME

Manual Setup
It is straightforward to manually enter the name and password for the network using the wlan.ssid and
wlan.passkey variables too. Be sure to save afterwards, or the values will be lost when the module reboots. Any
subsequent command requiring network access, such as an ICMP (Internet Control Message Protocol) ping,
automatically results in the module attempting to join the network.
