Use cases for Bluetooth BTLE on AP391x?


Userlevel 3
Hi,
AP3912 and AP3916 have integrated BTLE/802.15.4 radio. What can it be used for?

Hello htw
From our internal 10.21 Knowledge Transfer document these new AP's will support BTLE or 802.15.4 in a Future Release. This functionality is not yet active.

Bluetooth Low Energy (BLE) was incorporated into the Bluetooth 4.0 specification in 2010 and experienced rapid uptake, including all the major operating systems, many of the smartphones and tablets we use today, plus a new breed of devices like fitness bands and simple RF tags. BLE excels at sharing small packets of data, referred to as attributes, over a low energy link, and is frequently used for health monitoring, proximity detection, asset tracking, and in-store navigation. Access points contain an integral Bluetooth radio and dedicated antenna, providing superior coverage and convenience to support these applications. In other words, no other hardware is required, it’s all built-in.

BLE, as its name suggests, is designed to sip power, enabling some dedicated beacons to run for years on a single battery, opening up new practical applications at low cost. Bluetooth is also an efficient standard when it comes to radio interference. Operating in the 2.4 GHz ISM band, it uses frequency hopping technology to circumvent interference problems often seen in this band. Cell sizes can be tuned to the application requirement, with potential range comparable to 2.4 GHz WiFi, even taking into account the low power requirements of the standard.

Support enables customers to begin developing practical applications for BLE devices. These can be broadly categorized into ‘push’ applications, where the AP informs an aware device that it is in a certain location, or ‘pull’ applications, where the AP listens for beacons and uses this information to assist with asset tracking and control through the dashboard. Location analytics based on BLE generally work on an opt-in basis, with the consumer enticed via an app which leverages location for mutual benefit.

So how would the ble radio interact with an external application for example some location based app. Will this be a API to the controller?

To be honest I have no idea what Product Management has in mind for this new feature but if you have any suggestions we can submit them to PM for consideration.

I'm not an expert on R&D but I'd think it would make more sense to think about a use case of a product before it's finished.

Hey, as 10.31 with BLE support is now released could someone please explain the use case and what else I need to provide such service.

i.e. a trade fair - what systems do I need to get location information and how could I provide such information to the end user i.e. a map for the venue with his current location on his mobile device.

You'll generally need a third-party service to manage the integration, eg https://locatify.com/blog/indoor-positioning-systems-ble-beacons/ (first google result for [ble location]).

At a tech level, you'd need to write an app (or use a framework) that listens for the beacons and when it hears one of yours (they broadcast a (programmable?)128bit code) the app looks up the code in a database with the beacon locations to find out where you are.
