WASP User Manual Revision 1 6 c 2012 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 date 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 through both TCP and UDP protocols 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 into2. 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 it creates it s own Ad hoc network 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 lon battery when operating in Ad hoc mode as the network manager or up to 18 hours when joining an existing network Battery life is dependant 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 b
