WASP User Manual
Introduction
WASP is a standalone unit providing a bridge for ANT+ devices to communicate wirelessly through
Wi-Fi networks, to other devices on the local network or over the Internet. Utilizing an 8-channel
ANT+ receiver, on-board memory, power management circuitry and rechargeable Li-Ion battery,
WASP provides a data gateway for monitoring, recording and analyzing ANT+ data remotely.
WASP connects ANT+ devices to wireless networks for monitoring and data collection purposes.
For example ANT+ home scales, pulse-oximeter monitors, and blood glucose monitors as well as
heart rate monitors and all other ANT enabled devices are all able to use this bridge module to
communicate their data to central monitoring stations via the Wi-Fi network.
WASP is capable of receiving data wirelessly, from all certified ANT+ devices in the local area that
share the same ANT frequency. ANT+ device state is encapsulated as standard UDP messages,
allowing it to be routed through local networks, through the Internet or directly to any Wi-Fi
connected device. WASP can be configured directly over the network with a configuration utility
or a web browser. WASP is also capable of sending data to any ANT radio in range that is capable
of receiving data packets.
An Application Programmers Interface is available to OEM partners, allowing WASP integration
into custom applications needing wireless connectivity to ANT enabled devices at ranges which
exceed the typical ANT radio reach. WASP Wi-Fi is able to join existing networks with common
security protocols, or create its own access point allowing WASPs and application end point
devices (smart phones, tablet computers, Personal Computers, etc.) to join and share information
locally. WASP will run for up to six hours on its internal Li-Ion battery when hosting its own
network as the network manager or up to 18 hours when joining an existing network. Battery life
is dependent on the amount of ANT traffic local to the WASP. For fixed installation environments,
WASP can be powered from a USB power source.
In addition to the periodic streaming protocols, WASP supports ANT-FS sessions when coupled
with a Wi-Fi application or web host to manage the authentication, and file transfer requests.
When WASP is configured in ANT-FS mode, it searches for ANT-FS beacons. When a beacon is
found, it commands the device sending the beacon to change frequencies and await the
authenticate command. The Wi-Fi endpoint application or web host is then notified of the
connection and control is passed off to the host device to manage the data transfer. WASP
monitors the transactions assisting in connection management during the transfer process. Once
the transfer is complete (the connection is either closed or lost), it resumes searching for other
ANT-FS devices.
WASP can also be used as a bridge between multiple ANT+ nodes in distributed ANT+ network
topologies. Since ANT+ is a personal area network, it has a typical range of approximately 10 to 20
meters. If the ANT+ network is used as a mesh or hub and spoke topology, WASP can join
networks together that would normally not be able to communicate with each other because of
range limitations.
WASP is ANT+ certified and complies with all ANT+ device profiles.

Quick Start Guide
The Quick Start Guide leads you through beginning to use the WASP. It is simple to use, yet
provides all the ANT, ANT+, and ANT-FS functionality you need to work with the ANT enabled
devices.
WASP Button and Indicators
4.1
Getting Started
Out of the box, the WASP is configured to join a default Wi-Fi network (wasp). Follow the
directions below to configure the WASP to either join your local Wi-Fi network, or create its own
network. The WASP needs to be configured in order to connect it to an existing Wi-Fi network
other than the default. This guide walks the user through the process of setting up the WASP for
a specific operating environment.
© 2013 - 2014 North Pole Engineering, Inc.
Quick Start Guide
Turning WASP on/off or changing operating modes is performed using the button on the front
panel of the device. This button is a membrane switch so feedback on button presses is provided
by the green and red LEDs above the button. The red LED is on the left side of the label and the
green LED is on the right side. The green LED is primarily used to indicate the WASP is powered
on and shows its operational state. With a repeated single blink once every two seconds, the
WASP is hosting its own limited AP network. With a repeated double blink every two seconds,
the WASP has joined an existing network. Refer to Modes of Operation for additional details on
the operating modes.
The red LED is used to provide change of state feedback, indicate the state of the internal battery
charger and to indicate progress when joining Wi-Fi networks. Refer to Status Indicators section
under WASP Startup for details on the operating modes of the red LED.
The mini-USB connector on the back of the WASP or the micro-USB connector on the side of the
WASP is used to charge the internal Lithium Ion battery using either a USB connection on a
computer, or a stand-alone wall charger. It can also be used to configure the WASP via an
application running on a computer connected to the USB cable.
4.1.1

A solid red LED shows a fully changed battery.
A flashing red LED shows the battery is currently charging.
When the WASP is unplugged and in operational mode, tapping the black button will cause the
red LED to display the battery level
4 flashes, fully charged
3 flashes
2 flashes
1 flash, plug in to continue operation
Turning On the WASP
Pressing the black button on the WASP turns the green LED on immediately. Continue to hold the
button until the red LED turns on then release the button immediately. After you release the
button you will notice the green LED continues to flash. This indicates that the WASP has entered
operational mode.
The WASP actually has a couple of different modes of operation. The green LED indicates which
mode it is in.
1. A double flash signals the WASP is joining an existing Wi-Fi network.
Note: While the WASP is joining the network, the red LED flashes fast. While it is flashing a tap
of the black button causes the WASP to stop joining the network and proceed to create its own

WASP User Manual
network.
2. A single flash indicates a limited AP Wi-Fi network has been created.
Limited AP Mode
Limited AP mode can be entered by two different methods.
The primary method is to have the WASP enter Limited AP mode when it is attempting to join the
configured infrastructure network. While the Red LED is flashing fast when it is powered on, tap
the button. This causes the WASP to halt the join process and proceed into Limited AP/AdHoc
mode. This mode is indicated by a single flash on the Green LED once a second.
An alternative method of entering Limited AP/AdHoc mode is to disable the infrastructure mode
in the WASP configuration. When infrastructure is disabled, the WASP enters Limited AP/AdHoc
mode immediately after power up. This setup is useful if it is known the WASP will not be joining
an infrastructure network.
In this mode the WASP creates either an AdHoc or a Limited AP infrastructure network with the
same name as its serial number. PCs, laptops, and smart phones can connect to this network and
will be assigned an IP address in the range 192.168.240.10 to 192.168.240.18. All WASP
functionality is fully available in Limited AP Mode. In addition, a webpage is accessible at
192.168.240.1 for AdHoc Mode, and "config.wasp.local" in Limited AP mode for configuring the
Infrastructure Mode settings.
The choice between AdHoc and Limited AP mode is set in the WASP configuration. The factory
default mode is Limited AP mode. AdHoc mode is useful for maintaining the cellular data
connection when connected to an iOS product with cellular data capability. Since AdHoc devices
typically do not provide internet access, the iOS device continues to route data requests other
than WASP traffic to the cellular modem. Some devices are not capable of communicating in
AdHoc Mode, so Limited AP mode should be chosen for these devices.
Note: The battery will drain faster in AdHoc/Limited AP since hosting a network consumes more
power for Wi-Fi operations.
Infrastructure Mode
From power off, hold the button for one second and release after the Red LED activates. If the
WASP is configured to join an infrastructure network, the Red LED flashes fast while it is
attempting to join the network. The rapid blink on the red LED is used to indicate that the module
is searching for the network, attempting to join, authenticating, or negotiating an IP address. This
is called the Network Join indicator. Once the network association process is complete, the red
LED turns off or switches to the Charging Indicator if the USB cable is connected. The Network Join
Indicator will come back any time network connectivity is lost. All WASP functionality is fully
available in Infrastructure Mode. The configuration webpage is not available in Infrastructure
mode.
WPS Mode
© 2013 - 2014 North Pole Engineering, Inc.
Quick Start Guide
Important Note: This feature has been deprecated and will be removed from future
releases.
If the button is released after three flashes on the red LED, the WASP enters WPS Mode. This is
indicated by a repeated triple blink on the green LED. In this mode the WASP searches for a WPS
registrar and negotiates the exchange of SSID and WPA security information if one is found.
WASP uses the WPS push button method. This means you need to press the WPS button on your
AP/wireless router to put it into registrar mode and initiate the exchange. Do this after placing
the WASP in WPS Mode. The WASP will time out after two minutes if no WPS registrar is found.
If WPS fails or times out, the WASP will flash the red LED twice and return to Sleep Mode.
If WPS succeeds, the WASP will blink the green LED slowly three times, then update the settings
for Infrastructure Mode and immediately transition into Infrastructure Mode. The Network Join
Indicator will be active while the WASP is negotiating the new connection.
Restore Factory Defaults
Important Note: This feature has been deprecated and will be removed from future
releases.
Restore Factory Defaults is guarded by a specific button sequence. The button must be held from
power-off until the red LED begins flashing rapidly. It must then be released within three
seconds and quickly pressed again. The WASP will restore all settings to default and then power
off. This includes network settings for Infrastructure Mode.
If the button is held longer than three seconds or is not pressed quickly enough after release,
Restore Factory Defaults does not occur. This is indicated by three slow blinks on both LEDs
followed by transition to power off.
If the button sequence is performed correctly, Restore Factory Defaults does occur. This is
indicated by three slow blinks on the red LED only followed by transition to power off.
This special button press sequence is needed to prevent inadvertent resets if the button is held
while in a pocket or bag.
Status Indicators on the Red LED
These status indicators are provided in Limited AP and Infrastructure Modes only. They are in
priority order. Indicators earlier in the list override indicators lower down.

WASP User Manual
WASP Configuration
Configuration of Network Settings for Infrastructure Mode
Out of the box Infrastructure Mode is setup to join a network with the name "wasp". This network
likely does not exist in most environments, so the network settings for Infrastructure Mode will
need to be updated. The WASP allows three different methods for setting the network settings.
Webpage Update
The WASP can be started into the Limited AP Mode by pressing the button from the powered off
state and releasing after the green LED comes on and one flash occurs on the red LED. The WASP
will create an infrastructure network with the same SSID as its serial number. This network can be
joined by any PC, laptop, or smart phone. Open a web browser and navigate to "config.wasp.
local". The WASP will perform a scan of all networks in the area and present a webpage allowing
you to select from this list. Once you select a network, you are asked to enter a network password
and any advanced IP settings. Click "Next", then click "Save and Apply". The WASP then updates
the network settings for Infrastructure Mode. Note that the WASP is still in Limited AP Mode at
this point. You must power off and power back on into Infrastructure Mode.
WPS Mode
Important Note: This feature has been deprecated and will be removed from future
releases.
If you have physical access to your networks access point and the router supports Wi-Fi Protected
Setup, you can use this to set the network settings inside the WASP. Power the WASP on into
WPS Mode. From the off state hold the button until three red flashes have appeared on the red
LED, then release. The WASP enters WPS Mode, which is indicated by a repeated triple blink on
the green LED. Now press the WPS button on your network's access point. After a few moments
the WASP should see the WPS registrar hosted by the access point and begin a secure exchange.
The entire process takes several seconds. If the process is successful, the WASP will immediately
switch to Infrastructure Mode with the new network settings. This is indicated by three slow
blinks on the green LED, followed by a repeated double blink to indicate Infrastructure Mode. If
the process fails, the WASP sends two slow blinks on the red LED and returns to Sleep Mode.
WASP Configuration Utility
An iOS device or a PC connected to the same network as a WASP can be used to update its
network settings using the WASP Configuration Utility. This works in either Limited AP or
Infrastructure Mode. Use the Configuration Utility to connect to the WASP you wish to update
and enter the network settings in the network settings section. Click "Apply Settings" and
confirm your request by clicking "Continue". The settings are saved the WASP performs a reset
with the new settings. More on the WASP Configuration Utility is below.
WASP Configuration Utility
The WASP allows configuration of several settings in addition to the network settings for
Infrastructure Mode. A complete list of these settings, along with their default values, can be
found in Configurable Hardware Settings. The WASP is configured using the configuration utility,
which runs on either an iOS device or a Windows PC. The device performing the configuration
© 2013 - 2014 North Pole Engineering, Inc.
Quick Start Guide
must be on the same Wi-Fi network as the WASP that is being configured. Configuration can be
performed in either Infrastructure or Limited AP Mode. If configuration is being performed from
an iOS device for a WASP in Limited AP Mode, the network created by the WASP must be joined
manually. This needs to be performed using the Settings application of the iPhone, iPad
. If
using the Windows config application, the network is selected from within the application.
The configuration application lists all of the WASPs found on the network. Select one of the
WASPs to configure and select the option to connect to the WASP. Only one device is allowed to
open a connection to a WASP. If another device attempts to open a connection the WASP checks
with the currently connected device to find out if it is still connected and if it is willing to release
the configuration connect. If it is no longer on the network or it is willing to release the
connection the new device is granted access to the configuration interface. Otherwise it is sent a
message indicating the configuration interface is not currently available.
If the configuration connection is established the application then has access to the configuration
settings. A description of the settings is available in the Configurable Hardware Settings section
of this document. The default settings are found in Default Settings.
After the new settings are selected in the user interface, the changes are applied to the WASP by
choosing to apply the settings. When the WASP receives the command to apply the settings, the
internal configuration table stored in non-volatile FLASH memory is updated and the WASP resets
itself and attempts to join the preferred network using the new settings.
4.1.3
ANT+ Data
Once the WASP has established a network connection, it opens a UDP multicast socket at address
239.78.80.1. It then starts forwarding any ANT messages it receives from any ANT transmitter
configured to send on ANT RF channel 57 to the multicast address. If configured, the WASP opens
a unicast UDP socket and forwards ANT messages on that connection as well. The Multicast
Address and Port Number destination, the Unicast Address and Port Number destination, and the
ANT RF channel to monitor are all configurable using the WASP Configuration Utility. See the
settings in Configurable Hardware Settings.
The WASP allows two modes for forwarding ANT traffic. With Packet Saver mode turned off, each
ANT message received as packed and forwarded as an individual UDP packet. With Packet Saver
mode turned on, ANT messages are concatenated and sent together every 250ms (or quicker if
there is a lot of ANT traffic and packets are becoming too large). Each Wi-Fi packet is sent twice in
Packet Saver mode to help guarantee delivery, although the network traffic overall should be
lower. Packet Saver mode should be used if there is a lot of ANT traffic. Packet Saver mode
should be turned off if latency is a concern.
Packet Saver mode is enabled by default.
4.1.4
ANTFS Data
In addition to forwarding regular ANT traffic, the WASP can also listen for beacons from ANTFS
devices, if ANTFS mode is enabled (see Configurable Hardware Settings). Once an ANTFS beacon
is seen, the WASP will send a message to the ANTFS device informing it to switch its channel and
RF frequency. The WASP will reset its own ANT radio to these settings and then connect with the
© 2013 - 2014 North Pole Engineering, Inc.
10
WASP User Manual
ANTFS device. The only authentication mode allowed at this point is Passthru. Once connected,
the WASP downloads all files and forwards them to a preconfigured destination IP address and
port number. Files are sent using TCP for guaranteed delivery.
The Configurable Settings contain a few options to control which files can be downloaded and
forwarded. The Ignore Archive bit allows files to be downloaded and forwarded, even if they
have previously already been downloaded. This is normally disabled. In addition, the ANTFS
whitelists and blacklists allow for selecting or excluding specific file indexes and ANTFS device
types. These settings are described in further detail in Configurable Hardware Settings.
Once an ANTFS session is complete, a Disconnect command is sent to the ANTFS device with a
specific timeout. This timeout prevents the ANTFS device from going immediately back into
beacon mode, in which case the WASP would immediately connect again. The disconnect
timeout is configurable in Configurable Hardware Settings.
ANTFS mode is disabled by default.
Future Functionality:
Pairing and Pass Phrase Authentication
In the future the WASP will support passphrase authentication by requesting the passphrase from
the endpoint setup to receive the downloaded files. The WASP will read the serial number from
the ANT-FS client and send this serial number to the ANT-FS receive endpoint requesting the
passphrase in return. When pairing is set, the WASP will request the passphrase and then
provide the serial number and passphrase to the endpoint to save for future sessions.
4.2
Charging
WASP provides a mini-USB port to connect to a powered USB port on a computer or using a USB
(5V) wall transformer. This USB port is connected to the integrated Li-ion battery charger, which
monitors the status of the battery and controls the charge state. Once the battery reaches a full
charge, the charger stops the charging process and maintains a full charge level without
overcharging the battery so the WASP can remain connected to power indefinitely.
The red LED is used to provide feedback on the charging state of the WASP, both in the OFF and
ON states. When the WASP is attempting to join a Wi-Fi network in Infrastructure Mode, the red
LED is used to provide feedback on the progress of the connection process and does not provide
the feedback for battery charging.
When the red LED is flashing slowly the battery is charging. If the LED is a solid red, the battery is
fully charged.
Configurable Hardware Settings
There are a number of hardware settings that modify the operation of the WASP. The network
settings, described elsewhere in this document, the configured static IP, and DHCP settings all
affect WASP operation. See WASP Configuration for instructions on how to access and modify
these settings. See Default Settings for a full list of configurable settings, descriptions, and their
default options.

download/transfer is complete. It is the
length of time the device should wait before
resuming listening for ANTFS beacons. This
prevents the WASP from immediately
reconnecting. The disconnect time duration
is specifiable in increments of 30 seconds.
Modes of Operation
The WASP has operational modes which are selectable via the membrane button located on
the front panel of the device. The button area is defined by the black circle just below the
red and green LEDs. See WASP Startup for how to transition between different modes and
brief descriptions. Detailed descriptions are provided in this section.

6.1
Limited AP Mode
In AdHoc/Limited AP Mode the WASP acts as its own Access Point. The WASP creates either an
AdHoc or Infrastructure network with the same SSID as its serial number (i.e. "WA032105B4D").
The WASP can serve up to 8 IP addresses with a simple DHCP server. Note that the simple DHCP
server does not maintain a lease table. This means that any device that requests an address and
loses the connection may receive a different address when it attempts to reconnect. Also, if the
WASP creating the network is power cycled, it will restart the DHCP IP address assignments from
the initial IP address. This means devices that join the network can receive the same address as
other devices that had joined the network before the WASP was power cycled.
AdHoc/Limited AP Mode also provides a configuration webpage for the network settings used in
Infrastructure Mode. To access this webpage, first connect to the network being hosted by the
WASP with any PC, laptop, or mobile device. Then navigate to the URL 192.168.240.1 for AdHoc,
and "config.wasp.local" for Limited AP using any web browser. The WASP will perform a scan of
all networks in the area and then provide a list for selection within the webpage. There are also
options to set the security settings and IP configuration. If the browser is having trouble
connecting to "config.wasp.local" first make sure that your laptop is maintaining connection to
the WASP's network. If there is still a problem, your OS may be attempting to perform an MDNS
lookup on the URL only, and not a DNS lookup. Try entering "192.168.240.1" into the address bar
instead of "config.wasp.local". This problem has been observed occasionally with Mac OS X.
To enter Limited AP Mode, see WASP Startup for details.
All ANT operations are available in AdHoc/Limited AP Mode.
Note: The battery will drain faster in AdHoc/Limited AP since hosting a network consumes more
power for Wi-Fi operations than simply maintaining a connection.
6.2
Infrastructure Mode
In Infrastructure Mode the WASP joins a preconfigured network. The network settings are stored
in non-volatile flash and can be updated using three different methods. See WASP Configuration
for details. The default network settings are to join a network named "wasp", security is none,
and a blank passphrase.
Infrastructure Mode always attempts to maintain connection with the preconfigured network.
When the WASP is either searching for the network, associating, authenticating, or negotiating an
IP address, the Network Join Indicator will be shown. This is a continuous rapid flashing on the
red LED. If this indicator occurs during normal operation, it means network connectivity was lost.
To enter Infrastructure Mode, see WASP Startup for details.
All ANT operations are available in Infrastructure Mode.

WASP User Manual
WPS Mode
The WASP can join a Wi-Fi network via WPS (Wi-Fi Protected Setup) if the wireless Router or
Access Point is capable of participating in WPS operations. Wi-Fi Protected Setup (WPS) is a
computing standard for easy and secure establishment of a wireless network.
To initiate WPS mode, see WASP Startup for details. Once the WASP is in WPS mode, a
simultaneous operation needs to be performed on the Router or Access Point. Refer to the
documentation for that unit for details on entering WPS mode.
In WPS mode the WASP is either searching for or exchanging security information with a WPS
registrar. This is your Wireless Router or Access Point if it is WPS capable. The process can take
several seconds to complete. It will time out after two minutes if no registrar is found.
If WPS is successful the new network settings will be stored in non-volatile flash and the WASP
will perform three slow flashes on the green LED. The WASP will then reset into Infrastructure
Mode.
If WPS is unsuccessful the old network settings are kept and the WASP will perform two slow
blinks on the red LED. The WASP will then return to Sleep Mode.
ANT operations are not available in WPS Mode. All ANT operations will become available once
the WASP has successfully connected in infrastructure mode.
6.4
Sleep Mode
The WASP is in the Sleep Mode when both LEDs are off. In this state both the Wi-Fi and ANT
radios are powered off and the WASP consumes a minimal amount of power. To enter Sleep
Mode from any Operational Mode (Limited AP, Infrastructure, or WPS), press and hold the button
until three slow blinks occur simultaneously on both LEDs.
When the WASP is off, it is waiting for either a button press or USB charging connection. If the
button is pressed and held for at least three quarters of a second, the WASP will wake up and
enter the WASP Startup sequence.
If a USB cable is connected, the WASP will enter the Charging State but will remain off as far as any
ANT and Wi-Fi operations are concerned. USB Charging Sleep Mode is functionally equivalent to
Sleep Mode as far as button operations are concerned. A button press will wake up the WASP and
it will enter the startup sequence, but it will continue to charge from the USB port.
6.5
Charging State
When a USB cable is connected, the WASP is in the Charging State. It is in the Charging State
regardless of which mode it is in. Charging state is indicated during the Limited AP, Normal, and
Sleep Modes using the red LED. A slow blink indicates the battery is charging, and a solid on LED
indicates the battery is fully charged. The WASP can remain plugged in, at all times, to maintain
the battery in the maximum charge state. At times, the solid red will transition to blinking red
indicating the battery voltage has dropped to the point where the battery supervisor needs to
perform a maintenance charge cycle.
Notes:
The Network Join Indicator in Infrastructure Mode overrides the Charging Indicator.

Modes of Operation
17
In both Limited AP and Infrastructure Modes, the Battery Indication will not be provided if the
USB Cable is connected and the battery is charging. The Charging Indicator overrides it.
Being in the Charging State while in Sleep Mode does not affect push button operations. Any
user documentation that refers to a powered off state or Sleep Mode refers also to this state.
6.6
Restore Factory Defaults
Restore Factory Defaults is not a mode but an operation that can be performed from the powered
off state. Restore Factory Defaults will cause all user configurable settings to be restored to their
factory default state. This includes the WASP name, the Infrastructure Mode network settings,
ANTFS settings, and so forth. See Configurable Hardware Settings for a full list of user
configurable settings.
The following sequence will cause a Restore Factory Defaults operation:
1. Make sure the module is powered off in the Sleep Mode. It may also be in the Charging
State, with a USB cable connected.
2. Press and hold the button and wait for the following sequence.
3. 0.8 seconds to power on. Green LED comes on. (Keep holding the button).
4. 2 seconds to Infrastructure Mode. Two flashes on red LED. (Keep holding the button).
5. 2 seconds to WPS Mode. Three flashes on red LED. (Keep holding the button).
6. 5 seconds to Restore Factory Defaults Mode. Red LED is flashing continuously.
7. Release the button within three seconds of the WASP entering this state.
8. Quickly press the button again within half a second.
9. The WASP will indicate factory defaults have been restored by performing three slow
blinks on the red LED only and then returning to Sleep Mode.
If the WASP reaches step 6 above but steps 7 and 8 are not performed correctly, factory defaults
will not be restored. This is indicated by three slow blinks on both LEDs followed by the WASP
returning to Sleep Mode.
