Perhaps you would like to explain what the problem with this is? Broadcasting presence in itself is not a security hole - unless you think "Do not broadcast SSID" is a WiFi AP security feature (it's not). If WiFi can be secured (with devices that "scream data about themselves"), why would Bluetooth be any different? Well, there are a couple of reasons I think this is different: 1. APs are static and not mobile, versu…

Agreed. Checking for Bluetooth devices in the immediate area is one trick we teach in our physical counter-surveillance training for NGOs and journalists in high risk countries.

What app have you been using?

Not sure what the GP is using, but on Android the Nordic BLE app is very good - https://play.google.com/store/apps/details?id=no.nordicsemi.... I'm also one of the authors of RaMBLE, another BLE app ( https://play.google.com/store/apps/details?id=com.contextis.... ). It can run in the background, and can export logged BLE advertising packets and geolocation data to a SQLite DB.

I installed Ramble half an hour ago on my 2014 Moto G and it seems to be working as advertized! The only thing which confuses me is the empty list under the history tab. Is this a bug or is this feature not implemented yet?

The history tab is pull-to-refresh, but it's not particularly discoverable :)

I've implemented a UI hint to make this more obvious, which will be in the next version of RaMBLE.

Increased advertising length will be very useful. 31 bytes is rather stingy, especially with Eddystone-URL (you only get something like 16 bytes for the URL currently).

yes, 17 bytes for the URL.

What will it take for wireless keyboards and mice to use Bluetooth? Most ship with their own custom dongle. A single port MacBook, for example, doesn't really make sense until Bluetooth devices become more popular.

Apple's accessories are already bluetooth. I'm working with a magic trackpad 2 here and it skips all the time, as expected. Magic trackpad 1 did the same. So did my previous kinesis bluetooth keyboard. So does audio. Oh right, it's OS X that can't handle bluetooth. Or RF in the case of Logitech products. Hell, they have trouble keeping wifi on. What you wish for is already here and it's already shitty, at least on OS…

My Bluetooth devices work flawlessly with my iMac, including the Magic Mouse/KB etc. What's your RF environment like?

I wish they created a developer's only documentation to write drivers and apps for FOSS systems since the documentation is already huge.

That's what my initial thought was too. Sounds like severe 2.4GHz pollution.

You are right, pull-to-refresh was not very discoverable ;) Somehow I an auto-update function for a tab called "history".

Another thing I just realised is the number of new devices in the notification label. Let's say I put ramble in the background. After 10 minutes it tells me that there are n_1 new devices. I click on the notification in order to check them out. If I then put ramble in the background and it finds n_2 new devices then the notification says that there are now n_1 + n_2 new devices. I would expect that it says n_2 devices.

Yay, even better opportunities for government and corporations to track my whereabouts through my Bluetooth signature. ;) Tongue-in-cheek, well mostly but not entirely .. I do appreciate e.g. accurate travel times, yet refuse to believe they won't take it to the next step. http://www.theage.com.au/victoria/how-vicroads-tracks-your-e...

Modern Bluetooth devices, including all smart phones running Windows, iOS or Android, does not use static addresses that can be used as a signature to track you. Instead, they use private resolvable keys for all handshakes with devices around them. A new key is generated every few minutes, and only a device which you have previously bonded with is able to resolve your key through data exchanged in the bonding process…

Many BLE devices do not advertise with random addresses. iOS and Android do, but last I checked Fitbit and Tile do not.
