Knowing the MAC makes the attack reasonable - let's say 5 hours compute for 3080Ti.
Not knowing the MAC makes it exponentially harder. You can still "guess" it, but the search-space is vast and that would take bazillion-years.
So to attack iOS device: - user has to download the app - app has to broadcast fake BLE - some other devices (e.g. Android/RasPi would need to pickup that MAC and pass it to you
Using Core Bluetooth API it is trivial, but you need to either: a) create an app that does it and user has to download it b) modify SDKs existing in apps (e.g. Ad SDKs)
Also turning app/phone into a "BLE beacon" is only possible when app running in the foreground (on iOS).
In Project Aria video, they claim to have installed beacons at an airport to enable indoor location, only to dismiss it as something that "doesn't scale."
Instead, they say they "trained" an AI model using vision from glasses, allowing for vision-based localization.
So, here’s an honest question: which approach is actually easier, more cost-effective, and energy-efficient?
1) Deploying 100 or even 1,000 wireless, battery-operated beacons that last 5–7 years—something a non-tech person can set up in a day or two.
2) Training an AI model for each airport, then constantly burning compute power from camera-equipped glasses or phones that barely last a few hours.
Thoughts?
After almost 10 years of research and development, it is finally here - SpaceTimeOS, a new operating system for the physical world from we have been working on after we graduated YC.
With our new sensors (UWB/BLE/LTE) placed in the corners of any room and it will create a digital twin of any physical business and store it in the cloud where real-time position of all objects/people/vehicles is visible with inch-precise accuracy.
This digital twin can be manipulated with using JavaScript where developers can create automation, visualize and in general mold this digital replica of a physical world/business.
Happy to answer any questions...
this is Jakub, founder of Estimote, Inc (YC S13). Happy to share we have just launched a new device that has BLE, LTE-M/NB-IoT and GPS integrated.
It can compute its indoor and outdoor position and last years on the battery.
It is fully programmable using JavaScript and simple Web IDE.
Happy to answer any questions here!
We just launched a new Asset Tracking API. Bluetooth beacons attached to walls can now scan and locate smaller beacons attached to objects and pass that location data to the Cloud via low-power mesh network they create.
Via API it is possible to access quasi-real-time location of these assets on the floorplan.
If you have any questions we are around.
We have just released and published to GitHub https://github.com/Estimote/iOS-Indoor-SDK an update to Indoor Location SDK. It does use sensor-fusion built-it into ARKit, thus dramatically improves accuracy.
It is also possible to keep session persistence, so all mobile users in the same location will see the same virtual objects via AR mobile apps.
This Robot Operating System (ROS) SDK does use both radios. We use BLE and Bluetooth mesh to power UWB that are nearby to preserve energy of the system.
our beacons are commercially deployed in many verticals. SDK together with Cloud does allow some provisioning and security mechanisms.
Since beacons broadcast public Bluetooth signals we don't want any app/device to know their location in a venue that is not provisioned for the application.
For example you don't want AliBaba mobile app to know you are in Best Buy, next to console games.
That's why we do have optional encryption mechanism and our ToS prohibits reverse engineering our SDK.
Our customer have access via APIs to almost all raw data, so if they want to improve accuracy for their application they can do it.

Earlier this year we have added additional UWB radio to our BLE beacons. We did that mostly for floor-plan auto-mapping (read more here: http://blog.estimote.com/post/154460651570/estimote-beacons-...)
Many people asked us if it is possible for robots/drones/AGVs to connect to UWB beacons and get few-inches precision location positioning, so we have decided to release a ROS package.
You can install it on your Raspberry PI, connect to UWB beacons and start locating your robot/device.
We are around - let us know if you have any questions?

We just released a new beacon firmware supporting low-power routed mesh over BLE.
It's slightly different implementation that the one Bluetooth SIG has just standarized, but it will give you a good overview what is possible with Bluetooth Mesh.
If you have beacons already just upgrade the firmware and here is a nice tutorial: https://developer.estimote.com/managing-beacons/mesh-at-scal...
Feel free to post any questions - happy to answer them here.
Bluetooth range is aprox 100m and UWB range 70m, so that's the maximum distance between nodes. The more nodes you have the more accurate the shape is.
For a 1000 sqf office you would neeed probably 12-20 beacons. For a retail store more than a 100.
Thanks to time-of-flight technology beacons know the distance between each other and using Bluetooth mesh pass these data to cloud creating a floor plan automatically.
On top of that indoor location apps can be created. Happy to answer any questions here.
We just released a new firmware to support mesh networking with bluetooth beacons - you can read more on our blog: http://blog.estimote.com/post/153812538740/introducing-the-w...
Happy to answer any questions here! : )
We have just enabled in our SDK simple key:value storage for 1Mb built-in memory in our Location Beacon.
Your simple beacon apps don't need to store data in the cloud anymore; for some application you can keep content/sensor data/analytics directly in the nearby beacons.
Happy to answer any questions here : )
this is Jakub - Founder of Estimote (YC S13). FastCo Design did a great piece of our new product. It's essentialy a Bluetooth beacon powered by USB. Thanks to HDMI port it can be connected to any TV or digital display and it scans for BLE signals.
People with mobile apps broadcast these signals and can influence content of screens around.
You can read more how it works here: http://blog.estimote.com/post/150398268230/launching-estimot...
Will be more than happy to answer any questions here.
We just released a new revision of our Location Beacons. We implemented new, low power Nordic nRF52 chip and extended range to 200 metres (+10dB).
Beacons can simultanously advertise both iBeacon and Eddystone packets as well as telemetry & sensor data + they have built-in GPIO slot.
There is also 1Mb EEPROM, so you can read/write data directly in the beacon.
You can read more on our blog: http://blog.estimote.com/post/149362004575/updated-location-...
I will be more than happy to answer any questions here.
We just innovated with a new technique in which the next-gen device (in our case bluetooth beacon) is placed next to the old one to be auto-configured with the same settings. Thanks to that procedure all the existing apps and services will continue to work seamlessly.
With that approach it is easy to keep upgrading wireless infrastructures with the latest hardware in the quickly changing IoT environment.
This proximity-based concept can be easily applied to other devices installed in the physical world such us wireless routers, TV displays, POS terminals, etc.
Let us know what you think?
We just integrated the latest Nordic nRF52 BLE chip and made possible for proximity beacons with built-in programmable NFC. Beacons support iBeacon or Eddystone/Physical Web and might be a nice toy to play with latest Google Instant App Downloads via NFC/Physical Web feature.
Happy to answer any questions here.
Google has announced yesterday during IO in Mountain View an integration of two 1B+ users properties with beacon technology.
TL;TR - beacons can interact with users even if they don't have apps installed.
Google did great job making sure it won't introduce spam and will respect privacy.
I will be more than happy to answer any questions here.
Hope you will enjoy it since this post is also a little celebration for us and a nice start of New Year! : )
Last May we have announced a new robust mobile SDK for Indoor Location using beacons: blog.estimote.com/post/118294444205/super-simple-and-accurate-indoor-positioning-with
Today we are happy to announce that we have integrated Indoor Location with #nearables and allow tracking objects in the physical space with tiny, battery-powered beacons.
People who use mobile apps with our SDK opt-in to act as crawlers scanning for nearby beacons and updating their position when they walk around..
Hope you enjoy our tech and I will be more than happy to answer any questions here.
