Bluetooth when I’m connecting to a speaker

Bluetooth staying connected to my car when I’m 3 streets away
My dude! I can’t believe this is such a pervasive problem! Pretty much every person that I know who connects their car to their phone runs into this issue especially in the case of couples where both phones are paired and it’s just some kind of headbutting match to see which device randomly wins out, which is guaranteed to be the phone you didn’t want connected. In theory their priority system, but in practice Bluetooth device discovery and the connection process seems rather random.
I wish my car had an option to disable auto connection and a prominently displayed button to explicitly connect to a recent phone upon request.
Ugh, the car!
I live in the heat. I have to start to car before hand, just to make it so the family doesn’t melt to the seats. It connects. I switch it back to my headset. I go back in the house to get stuff to load up, and I go out of range. Get back in range. It connects again. I switch it back to the headset. I forgot something…
Rinse and repeat like 5 times before I’m good to go. Whole time, I’m only catching every 10th word of whatever someone is saying to me on the phone, thinking it lost service, or they hung up on me.
I hate auto connect.
Bluetooth headphones when I want to use them:
Bluetooth headphones when there’s someone calling and I can’t answer because I can’t find them:
The number of times I’ve been mid video call or watching a video on my headphones and they randomly decided to disconnect from my laptop and connect to another device like my phone absolutely infuriates me.
The whole multiple paired device feature really needs some work…
It might be your phone getting a notification, and sending that to the BT speaker, which then takes precedent over the laptop
I usually just disable BT on my phone when stuff like that happens (on android, you can change the playback device without disconnecting, and that should also prevent the phone from stealing your headphones)

You can do this quite easily on iPhone as well, I was delighted to discover when my beloved OnePlus 7T Pro died and I went to the Dark Side.
There might be something to that. Unfortunately I keep Bluetooth on for my smart watch to connect. The headphones aren’t normally selected, but I think they auto-connect sometimes when they come in range. It also doesn’t help that the main way of switching the connected device is via the Android app, that requires the phone to use. (Original Surface Headphones, I’m considering replacing them because the pads are falling apart already)
Wait, do you just keep your Bluetooth on when you don’t need it? Is that… are people doing that?
Even if you turn it off the radio is still powered on and scanning in the background (wifi too), unless you specifically disable that as well. The battery drain is negligible
it can be a security issue leaving it on. also can drain battery as its occasionally pinging for nearby devices.
So is literally any communication standard on your phone…just turn off wifi, nfc, cellular network and Bluetooth then you’ll be safe
I wonder if this has anything to do with how the bandwidth is automatically decreased when taking a call vs when you’re just playing audio. Less bandwidth means a slower but more robust connection or something like that?
I don’t think BT devices do frequency hopping. The audio bandwidth is reduced just because the mic signal is added and has to share the connection. There’s no change on the physical connection.
(Now, it would be great if there was some frequency hopping and your phones could reserve a full FM channel instead of messing with digital compression.)
That decreased bandwidth would still help to maintain a digital connection though, wouldn’t it? There’d be a weaker and slower connection as the devices get further apart, so I was thinking less demand on the connection would keep them from dropping it.
I don’t think it’s the same as what you meant exactly, but I looked it up and Bluetooth does hopping between 2.402 and 2.480 GHz.
