1. WASP User Manual Revision 2 2 c 2013 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 NPE WiFi IT module 8 channel ANT receiver on board memory power management circuitry and rechargeable Li lon 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 WiFi 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 TCP IP 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 ora 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 integr2. 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 if the button is released after two flashes on the red LED the WASP enters Infrastructure Mode This is indicated by a repeated double blink on the green LED In this mode the WASP attempts to join the pre configured infrastructure network A 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 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 fora 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 pr

4. 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 alot of ANT traffic Packet Saver mode should be turned off if latency is a concern Packet Saver mode is enabled by default 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 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 c 2013 North Pole Engineering Inc Quick Start Guide 9 whitelists and blacklists allow for select
