© 2013 - 2014 North Pole Engineering, Inc. 2 WASP User Manual 1 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.

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.
Quick Start Guide 5 © 2013 - 2014 North Pole Engineering, Inc. 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 WASP Startup Battery Indicator When the WASP plugged into USB power, the red LED provides the feedback of the battery charging 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
© 2013 - 2014 North Pole Engineering, Inc. 6 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
Quick Start Guide 7 © 2013 - 2014 North Pole Engineering, Inc. 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. Name Description Network Join Indicator Charging Indicator Battery Indicator Rapid blink on red LED. Provided in Infrastructure Mode only. Occurs while searching for or negotiating a network connection. If the LED is rapidly flashing for a WASP that was previously connected in Infrastructure Mode, that's a sign network connectivity was lost. Provided if USB cable is connected. Slow blink indicates battery is charging. Solid indicates battery is fully charged. One to four blinks indicating battery level. One blink is the lowest level. Four blinks is the highest. Battery indication is provided by pressing and releasing the button within 1 second while in Limited AP, Infrastructure, or WPS Mode. Battery Indication is not provided if the Charging or Network Join Indicator is active.
© 2013 - 2014 North Pole Engineering, Inc. 8 WASP User Manual 4.1.2 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
Quick Start Guide 9 © 2013 - 2014 North Pole Engineering, Inc. 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. 5 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.
Configurable Hardware Settings 11 © 2013 - 2014 North Pole Engineering, Inc. 5.1 Default Settings User Setting Factory Default Value Description WASP Name 17 character MAC Address of the WASP The WASP name is a 32 character field used to provide an ASCII name to identify the WASP. This can be changed using the WASP Configuration Utility. Changing the WASP Name does not affect the network name created in Limited AP Mode. It does affect how the WASP identifies itself to any WASP specific programs and utilities connected to the same network. Infrastructure Mode Network SSID wasp The network name used to identify the Wi-Fi network the WASP attempts to join when in Infrastructure Mode. The network name has a maximum of 31 characters. Infrastructure Mode Network Security None The security type used for joining an encrypted network. Options include WEP, WPA, WPA2 or None. Infrastructure Mode Network PassPhrase (Blank) The network security key used when connecting to a network in Infrastructure Mode. This may be a WEP Key hex string if security is set to WEP, or a passphrase if security is set to WPA/WPA2. A WPA passphrase has a minimum length of 8 characters and a maximum length of 64 characters. Infrastructure Mode DHCP ON The DHCP selection determines if the WASP will attempt to get an address from a DHCP server when it joins the Infrastructure Mode network or use a static IP configuration. If DHCP is turned off, the IP configuration is given by the IP Address, Subnet Mask, and Gateway IP settings outlined below. Infrastructure Mode IP Address 192.168.89.10 IP address to be used in Infrastructure Mode if DCHP is off. Not used if DHCP is on. Infrastructure Mode Subnet Mask 255.255.255.0 Subnet mask to be used in Infrastructure Mode if DHCP is off. Not used if DHCP is on.
© 2013 - 2014 North Pole Engineering, Inc. 12 WASP User Manual Infrastructure Mode Gateway IP 192.168.89.1 Gateway IP address to be used in Infrastructure Mode if DHCP is off. Not used if DHCP is on. Packet Saver Enabled ON With Packet Saver mode turned off, each ANT message received is 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. RSSI Enabled OFF Not yet implemented. Archive Ignore Enabled OFF In ANTFS mode, when downloading files from an ANTFS device, the WASP normally ignores files with the Archive bit set (files that have already been downloaded). The WASP can be made to ignore the archive bit by enabling this flag. ANT-FS Enabled OFF Allows connecting to ANTFS enabled devices, downloading files, and forwarding them to a preconfigured TCP server. See ANTFS Data for a more complete description. Created Network Type Limited AP The WASP can create either an AdHoc network or Limited AP network when creating a network. Direct UDP Routing Destination IP Address 0.0.0.0 This specifies a single destination to forward all ANT traffic. Since this need not be a multicast address, it allows ANT traffic to be sent to a remote network. Only one unicast destination address may be specified for ANT traffic. Direct UDP Routing Destination Port Number 0 Used in conjunction with the Direct UDP Routing Destination IP Address. Multicast UDP Routing 239.78.80.1 This specifies a multicast group address that
Configurable Hardware Settings 13 © 2013 - 2014 North Pole Engineering, Inc. Destination IP Address allows multiple devices to receive ANT traffic forwarded by this WASP. Although multiple devices can subscribe to the multicast group address, multicast transfers are usually limited to the local network subnet. Multicast UDP Routing Destination Port Number 51113 Used in conjunction with the Multicast UDP Routing Destination IP Address. Operational Mode Streaming Operational modes supported are Streaming, Proximity, and Access Point. The proximity mode also has a range setting that adjusts the distance a device is detectable from the WASP. ANT Network Key Selection ANT+ Network Key The default eight byte Network Key can be selected to be either Public, ANT+, ANT-FS, or Custom. If Custom, the Custom ANT Network Key is used. Custom ANT Network Key 12-34-56-78-90-AB- CD-EF The custom network key is used when ANT Network Key Selection is set to Custom. ANT Channel 57 ANT radio beacon frequency to listen for ANT and ANTFS traffic. ANT-FS Destination IP Address 192.168.240.10 Address of TCP server that ANTFS files should be sent to during ANTFS file download and forward operation. Note: The default value is the same as the IP address assigned to the first connected device in Limited AP Mode. This is useful for testing. ANT-FS Destination Port Number 55555 Used in conjunction with ANT-FS Destination IP Address. ANT-FS Device Type White List All 0s A list of Device Type, Device ID pairs that can be used to whitelist specific ANTFS devices. Device IDs can be contain wildcards with a zero value for a specific Device Type. The list holds up to eight entries. Note that bit 7 (the pairing bit) of the Device Type is masked out when comparing to the whitelist. An empty list means the whitelist is not used. ANT-FS Device Type Black All 0s A list of Device Type, Device ID pairs that can
© 2013 - 2014 North Pole Engineering, Inc. 14 WASP User Manual List be used to blacklist specific ANTFS devices. Device IDs can be wildcarded with a zero value for a specific Device Type. The list holds up to eight entries. Note that bit 7 (the pairing bit) of the Device Type is masked out when comparing to the blacklist. An empty list means the blacklist is not used. An entry in the Device Type Black List will override any entries in the Device Type White List. ANT-FS File Index White List All 0s A list of ANT-FS File Indexes to be whitelisted. Any file indexes not in the white list are excluded from download. An empty list means the whitelist is not used. ANT-FS File Index Black List All 0s A list of ANT-FS File Indexes to be blacklisted. Any file index specified by the black list is excluded from download. An empty list means the blacklist is not used. An entry in the File Index Black List will override any entries in the File Index White List. App Specific Disconnect 0 Byte sent for the application specific disconnect field when the ANT-FS session issues the disconnect command Disconnect Time Duration 1 = 30 seconds Disconnect time duration to specify to ANTFS enabled devices. The time duration is sent as part of the disconnect command after file 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. 6 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.
Modes of Operation 15 © 2013 - 2014 North Pole Engineering, Inc. Limited AP Mode Infrastructure Mode WPS Mode Sleep Mode Charging State Restore Factory Defaults 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.
© 2013 - 2014 North Pole Engineering, Inc. 16 WASP User Manual 6.3 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 © 2013 - 2014 North Pole Engineering, Inc. 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. 7 WASP Hardware 7.1 Wi-Fi Key Features FCC/IC/Wi-Fi Certified 802.11 b/g/n Compatible (Requires 802.11b enabled on network) Dual ARM7 Processors for application and networking Small Form Factor (1.28” x 0.9” x 0.143”) Security: WEP128, WPA-PSK and WPA2-PSK (TKIP / AES) -40 to +85 °C Operating Temperature Range
