Referencedesign til Bluetooth Smart beacons

Nordic Semiconductor lancerer 'Bluetooth Smart Beacon Kit', der er et referencedesign, som gør det muligt at demonstrere og udvikle iBeacon samt proprietær beacon hardware til for iOS og Android smartphones (in english).

The future of beacons has many exciting possibilities such as indoor micro-location or 'Indoor GPS'. The major use case currently is for 'contextual awareness' providing users with information relating their proximity to a Point of Interest (POI). While the beacon itself relays only its identity, it is the smartphone, through the use of an app or direct services, which provides all the information that the user can access that relates to the particular beacon's location.

The range of use-case scenarios for beacons is correspondingly virtually unlimited, and could include special deals at retail stores, products available in stock, exhibits in public galleries and museums, train and bus terminals, and shopping list reminders.

In operation, Bluetooth Smart beacons use advertising packets that include fields to indicate the beacons' identity. The smartphones use internal Received Signal Strength Indication (RSSI) to estimate distance between handset and beacons.

Whilst beacons themselves only relay advertising to the smartphones and not contextual information, the smartphones use the advertising packets to determine the beacon's identity (using, for example, the phone app), and decide upon the information and/or actions that should be associated with that beacon's location. Permitted actions will vary between phone vendors, depending on imposed limitations, but may include audible alerts, vibrations, and triggering of other apps.

The nRF51822 Beacon Kit employs Nordic-developed hardware, firmware, and software and supports both iOS 7 and Android (4.3/4.1) operating systems. As each brand and model of smartphone exhibits different RSSI levels (due to electromagnetic variations stemming from, for example, the individual casing enclosure or antenna employed) the nRF51822 Beacon Kit has a tuning function that allows consistent performance regardless of phone model.

The introduction of Apple's iBeacon service in 2013 has generated great interest in beacons and many stores now want to leverage the possibilities of contextual marketing. Apple Stores began rolling out iBeacons in 2013 that work with the Apple Store App. This was the first introduction of iBeacon technology on a large scale bringing an even richer consumer experience to shopping at the Apple Store. The nRF51822 Beacon Kit can be configured for iBeacon compatibility. Membership of Apple's "Made For iPhone" (MFI) program is mandatory for iBeacon development.

The nRF51822 Beacon Kit is a fully functioning demonstrator of Bluetooth Smart beacon technology. All design files are also available from Nordic and allow for customization to a designer's requirements.

- Beacons represent a use case that has an immediate draw to the commercial world, comments Thomas Embla Bonnerud, Nordic Semiconductor's Director of Product Management. - Marketing has become progressively more directed and personalized over the last few years and the use of beacons takes that shift a stage further. For instance, consumers can now be made aware, in real time, of items they need to make a recipe, of special offers on products, and whether items are in stock. The possibilities are limitless. Additionally contextual awareness can be brought to environments such as museums and railway stations where individuals have a need to pick up location-based information.

- Nordic Semiconductor has always led the field in cutting-edge application support for developers with ultra low power wireless. With the nRF51822 Beacon kit we are continuing that track record for Bluetooth Smart beacons.
