I live in a big city in the center. When i activate "Show bluetooth devices without names" in the developer settings of my android 13 phone, there appear loads of this devices. I have no clue what they are. Does anyone know? Are that the bluetooth nanobots of the vaxxinated people? (/s to last question!)

Probably just because you live in a big city and there are a shitload of bluetooth devices around. If you're worried, try moving out of bluetooth range and scanning again to see if any of them don't change.

All those spiders that you're never more than 10 feet from have started using fitness wearables, and with 8 arms each that's a lot of bluetooth nearby.

[–] mvirts@lemmy.world 27 points 1 year ago (1 children)

Don't forget the birds. They want us to think they're eating the spiders. It's actually more like Uber for spiders, they use Bluetooth for ride hailing.

[–] bionicjoey@lemmy.ca 25 points 1 year ago (1 children)

Birds don't use Bluetooth. They use 5g in order to connect to the government surveillance drone network

[–] DemBoSain@midwest.social 10 points 1 year ago

Haha, birds. Right,lol.

[–] nothacking@discuss.tchncs.de 115 points 1 year ago (1 children)

Bluetooth devices only broadcast their name when in pairing mode, at other times only the mac address is available. In other words, these are just people's Bluetooth devices like headphones, cellphones, airtags, etc.

[–] coffeebiscuit@lemmy.world 76 points 1 year ago (1 children)

… tv’s, soundbars, remotes, keyboards, mouses, media players,… fucking toothbrushes, vibrators, mirrors, etcs.

[–] Waker@lemmy.ml 53 points 1 year ago (1 children)

Please don't fuck toothbrushes :(

[–] RedditRefugee69@lemmy.world 18 points 1 year ago (1 children)

What if they vibrate though?

[–] kafa@lemmy.ml 6 points 1 year ago (1 children)

they map in Bluetooth as vibrators then

[–] Norgur@kbin.social 7 points 1 year ago

You'd think... Mine didn't... Had to write a whole wrapper with kernel module and all...

[–] federalreverse@feddit.de 106 points 1 year ago (2 children)

They may just be other people's various devices. Maybe IoT devices or devices not fully set up. If you're living near a store/above a store, those might be Bluetooth beacons that track people through the store.

[–] WhatsHerBucket@lemmy.world 38 points 1 year ago (1 children)

TIL about Bluetooth beacons. I assumed people were tracked, but I didn’t consider it was via Bluetooth.

[–] ChicoSuave@lemmy.world 60 points 1 year ago (3 children)

Bluetooth personal networks have been a thing for about a decade and are used for monitoring traffic density and flow by third party companies. It's partly why Apple was removing their aux ports and pushing for Bluetooth so much, they are making money with tracking their statistically significant user base. Google does it too and it's most readily evident with Maps traffic filter.

If you've wondered why enabling Bluetooth asked for iPhone location to be enabled, now you know.

Just wait until you hear about how AirTags work:

Apple AirTags emit a Bluetooth signal that anonymously connects to any nearby device active within Apple’s Find My network (any iPhone after iPhone 11 with "Find My" enabled). The AirTag’s location is triangulated based on the strength of the Bluetooth signal sent to those third-party devices.

Your AirTag’s location information is uploaded to the cloud and pinned on a map for easy reference.

[–] TdotMatrix@lemmy.ml 8 points 1 year ago (2 children)

That's how it's expected to work, yes. As does Samsung SmartTags, and Tiles. These tracking devices (that we purchase and opt-in for) are a net positive in most cases. How else would we expect them to work if not for Bluetooth beacons (and UWB)?

Because you have lots of BT devices around you!

[–] Blackmist@feddit.uk 44 points 1 year ago (3 children)

Stasi listening devices. We never went away, comrade.

[–] PlexSheep@feddit.de 23 points 1 year ago

Nowadays, people buy them out of free will. They give them names and ask them to play Despacito.

[–] SomeBoyo@feddit.de 16 points 1 year ago

Can confirm (posted from a Stasi listening device)

[–] PixeIOrange@feddit.de 7 points 1 year ago

God dammit.

[–] dQw4w9WgXcQ@lemm.ee 40 points 1 year ago (2 children)

I have replaced almost every light bulb in my house with smart bulbs which feature both bluetooth and zigbee connections. It's around 40 devices. If your neighbour has smart bulbs or other devices, I guess that could be a large part of it.

Our Aldi now has electronic price tags for each product in the centre aisles. I wonder if they're Bluetooth.

[–] PixeIOrange@feddit.de 10 points 1 year ago

I have an idea, there are some restaurants around, maybe its these restaurant pagers.

[–] YodaDaCoda@sh.itjust.works 9 points 1 year ago

It varies. Some of them use Bluetooth Low Energy, some of them use other wireless techniques for lower power and greater range.

[–] EddoWagt@feddit.nl 8 points 1 year ago (1 children)

They're usually e-ink displays that get their power from NFC, so they're probably not Bluetooth

Could be anything, since you're in the middle of a large city center. Could be smart devices, could be FindMys or similar, could be beacons, could be trackers, could be any combination.

[E]. To answer your nanobot question. I guess it could be nanobots, though all of the ones I've ever seen, use NFC. Also, "of the vaxxinated people"? I haven't heard that one before. What is that about?

[–] kzhe@lemm.ee 33 points 1 year ago (1 children)

It's a reference to conspiracy theories about vaccines containing trackers

[–] 01189998819991197253@infosec.pub 11 points 1 year ago (7 children)

Oh... didn't realize that was a thing. That's.... a bit disturbing....

I think those are electric scooters if your city has those. When im around a lot of those things my device list looks just like this

[–] ours@lemmy.film 18 points 1 year ago (1 children)

That's perfectly normal, pay no mind to them or the plumber van parked day and night on the other side of the road.

If I had to guess you probably live in a big city in the center. This means when you activate "Show bluetooth devices without names" in the developer settings of your android 13 phone, there appear loads of devices. You probably have no clue what they are because none of them are your devices so why would you know what they are?

So many electronics now have a Bluetooth chip, wether they use it or not. If you have AirPods, that’s up to 3 BY devices (each ear plus case), each phone, each computer (+ mouse, keyboard), TV (+ remote controls), game pads, Bluetooth speakers (plus extra of stereo or 5.1). A lot of small devices too now have Bluetooth like some Arduino boards can Raspberry Pi,

[–] collegefurtrader@discuss.tchncs.de 7 points 1 year ago* (last edited 1 year ago) (6 children)

Every single node in any form of β€œsmart home” networks including color changing light bulbs

[–] TheButtonJustSpins@infosec.pub 6 points 1 year ago (2 children)

Most of those use other networks - Zwave, Zigbee, or WiFi.

[–] collegefurtrader@discuss.tchncs.de 4 points 1 year ago (1 children)

Many of them use Bluetooth or BLE for setup purposes and im sure some don’t bother to stop advertising

Try using RamBLE or nRF Connect to see some more info about the devices

You can use the 1st half of the mac to lookup the vendor (OUI)

[–] techwooded@lemmy.ca 8 points 1 year ago

Just in case

[–] Darkassassin07@lemmy.ca 8 points 1 year ago

Smart devices like switches, bulbs, outlets, etc; air tags and other brands of Bluetooth tracker; wireless speaker systems, headphones.

Many of these devices won't broadcast a name at all, or will only broadcast a name while pairing.

[–] MooseBoys@lemmy.world 8 points 1 year ago

I see 21 devices in just my house. Many Sonos speakers (no name when not advertising BT input). Several air monitors. All my TVs. A temperature tracker. Three smart switches…

There's an app called AirGuard put out by a German university, it scans for air tags in your vicinity. Useful if you are worried about someone slipping an AirTag on your person/belongings to track you.

[–] WhoRoger@lemmy.world 5 points 1 year ago (2 children)

When i activate "Show bluetooth devices without names"

I think that option just shows MAC addresses (or whatever it is BT uses) instead of the devices' names?

[–] Revan343@lemmy.ca 14 points 1 year ago (1 children)

It shows all Bluetooth devices in range, whereas normally Android only shows ones which your phone knows the name of, either because they're in pairing mode and thus broadcasting their name, or because you've paired before.

[–] WhoRoger@lemmy.world 4 points 1 year ago

Ah, interesting
