Hacking Bluetooth Low Energy: I Am Jack’s Heart Monitor



Bluetooth Low Energy (BTLE) is the hottest new mode in the latest and greatest Bluetooth 4.0 spec. A new generation of wireless devices, including medical devices will be implemented using this mode.

BTLE is much simpler than classic Bluetooth. Simpler to implement, simpler to debug, and hey, simpler to hack.

I present the progress of a BTLE sniffer/smasher/smusher written for Ubertooth in this WIP talk.

London’s Gatwick Airport now has 2,000 beacons for indoor navigation

Sophisticated indoor environments like air-ports and department shops can be a nightmare to find your way around. And while Google is seeking cell phones with 3D detectors as one possible solution for places GPS won’t precisely reach, another approach is to kit out an interior with a whole lot of Bluetooth beacons – giving phone users located-locked pings to fix onto to recognise where they’re.

The UK’s second busiest air-port, Gatwick airport, has decided on the second approach to power an indoor navigation system it’s launching as an element of a larger, multi-year transformation program.

It’s currently completed providing its two terminals with roughly 2 Thousand battery-powered beacons to make sure digital map users will get a more accurate blue dot as they go around. The beacon system will likewise be used to power an augmented reality wayfinding tool – to make sure mobile users can be guided to particular locations within the terminals through on-screen arrows. The beacon system is slated as backing up positioning with +/-3m precision.

Gatwick is planning to integrate indoor positioning into some of its applications, and says it’s in discussions with airlines to make use of it for their own applications and services – giving illustration of them having the capability to send push notifications to alert people if they’re running late, or even make a decision on if they should wait or offload luggage so a plane can take off punctually.

Merchants and other third parties will likewise be able to utilize the system for proximity detection of potential clients and push marketing and advertising messages – at a minimum to those who have opted in to receive them.

Gatwick says it will not be gathering any sensitive information with the beacons but says “generic information on ‘people densities’ in different beacon zones” will be used to help improve airport operations – for example, queue measurement, streamlining passenger flows and cutting down obstruction.

The airport has worked with UK startup Pointr on the system. Along with developing software and managing the system on an ongoing basis, Pointr provides an SDK with support for 3D AR wayfinding make it possible for third parties to tap into the functionality.
