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.

Eagle PWB Design With Matt Berggren

pcb-design

Eagle is a household name for more or less all Hackaday regulars. Here is your chance to read about upcoming features, have your ‘how do I do this in Eagle?’ questions replied, and get your wishlist items heard. Come along on Friday at 12:00 PST for a real-time Hack Chat in relation to the Eagle PWB Design software package.

Hosting this week’s chat is Matt Berggren, best known on Hackaday.io as technolomaniac. Matt is the Director of Autodesk Circuits and with Autodesk’s buying of Eagle last summer, the well known schematic design and PWB layout software falls under his acumen. He’s got a comprehensive back ground in designing printed circuit boards -if you possible could do it in EDA software he is sure of how -it is a good chance to get responded the important questions that were stumping you.

Please do not pass up this Hack Chat! And here is a convenient web-based tool that will help turn 1/13/17 at 12:00 PST to your local area time.

Here’s How one can Be Involved:

Hack Chat are live community activities that happen in the Hackaday.io Hacker Channel. Take a look at that web page (verify that you are signed in) and seek the “Join this Project Button” in the top right. After you are associated with the Hacker Channel, the button will plunge to “Team Messaging” that walks you to the Hack Chat.

You don’t have to lose time waiting for Friday, join Hack Chat whenever you like and watch what the community currently is speaking about.

Come Along Next Week Way too for KiCad!
Are you a greater portion of a KiCad guy than an Eagle guy? You need to still check out this week to ascertain if Matt changes your opinions. But filter out your calendar next week when Wayne Stambaugh, among the list of lead developers of KiCad will arise for a Hack Chat on Friday, 1/20/17.
