How do Galaxy Buds connect with Bluetooth turned off?

Lonath · Mar 13, 2019

I mean it's a great feature and is awesome that it works with Bluetooth turned off on the phone, but how do the buds communicate to the phone?
High frequency audio or something?

They aren't connected, or you do have Bluetooth turned on. It's physically impossible for them to be connected with Bluetooth turned off. That's literally how they connect to the phone.

If you have Bluetooth turned off, open the Buds box, then see the prompt on the screen, this is because Bluetooth is turned back on by the Samsung SmartThings service. It can detect the Buds and it turns BLuetooth back on to connect to them.

Oh, so you are saying that, "turning off" Bluetooth doesn't really turn off Bluetooth?

Well, after it connects it is using Bluetooth obviously, the question was the part it communicating with the phone when Bluetooth was off

Probably delayed cut- off after you have it disconnected.

Well, when Im going for lectures, I use the Galaxy Buds and when the lecture starts I close em and turn off Bluetooth, after the lecture finishes, while Bluetooth is still of, opening up the galaxy buds case still brings the pop-up, even after 2hrs

This is the feature of Bluetooth 5, called the beacon technology. So your device can communicate with bluetooth devices nearby even if the bluetooth is turned off. The bluetooth 5 offers the off state which can be utilized to request the device to turn on the bluetooth by a neighbouring device. So you saw your bluetooth turned on after the popup appeared as it used the beacon technology. The location services needs to be on for this.

Thanks for the great explanation, but if you checked my video, you would see that "Location" was turned off.
It is possible that it uses that technology you stated.

Edit - it probably uses the 'nearby device scan' setting for that instead of location

Edit 2- and yes it does, it no longer pops up when you turn off 'nearby device scan'

yes, depending on the app, it can use get the location either by location services or nearby device scan.

To all of the people saying your bluetooth must be on have you opened your buds pro with Bluetooth off? Obviously not if you open the case with Bluetooth wifi and nfc off it still pops up and asks if u want to connect to them I was also curious how this works and only found know it alls that know nothing

NFC is also bluetooth, and being part of home automation... now you know

Edit: I suspect they'll drop bluetooth soon for NFC

Correct I believe.
I have SmartThings, WIFi and NFC disabled at all times. If bluetooth is on, the Buds+ engage seamlessly once inserted, if bluetooth is off it needs to be turned on and reinitialized.

Nfc in mobile fones is like the camera and mic, you cant turn it off. the end user is shown it disabled, but nowadays, even phones tell lies. Your smoke alarm at home (scotland installing mine soon), power meters... washing machine... try turning the power meter one off!!

Or the damn smoke alarm!

It works like this:

How does your NFC bank card work?

Where is the power in the bank card?

Nuff said.

Package Disabler kills it. A adb edit will too.
I keep my N10+ on a short leash.

Do that with your bank card... tinfoil handbags lol... its that bad, (no offence here), you dont see Nfc as bluetooth.

Nfc apps only connect to bluetooth HARDWARE. removing the app or editing only messes with the app, not the hardware.

Edit: Keeping in mind we're almost all on OVERLAID file system... the real nfc is LIVE like your camera and mic and... bank card lol, the overlaid appears disabled.

Edit 3: in effect, john wu wants the skill set you have because if you COULD turn off, you'd have the answer to root he needs.

I say this with respect to both you and wu.

Don't know, never use it. It's also turned off in settings... I like my Android's dumb.
As far as I can tell it's fully disabled.
Lol, I have a RF shielded wallet.

you posted while I was editing.

I dont trust fones, so dont trust their claims.
