[Q] Bluetooth Devices Disappear?

I have been patrolling the forums trying to find a solution (or at least a thread similar) to my problem. I made the move from the G1 to the Vibrant in Aug. I was spoiled by it so it feels. I've grown quite custom to my Bluetooth devices being remembered by my phone, and not having re-sync them everytime i want to use them. I'm wondering if there is a fix for this, or is this apart of the Vibrant framework and i just have to get over it? Has anyone else been experiancing this?

Speak now or forever hold your piece. This is a huge nerd farm and im sure we can all put our heads together.

Are you talking about pairing or connecting the device? I only have one bluetooth device with my phone, and the phone has no problem staying paired to it. I do have to reconnect it when I turn on bluetooth, but that's all.
To clarify:
I turn on bluetooth.
My headset is shown on the devices list.
I press it once and it connects.
Device is ready to use.
Once, the device didn't show in the list while BT was off, but when I enabled BT the device was displayed.

What i mean is, I normally have more than one BT device connected. More specifically my BT headset, and my car BT stereo. I used to be able to have both devices remembered in my device list. But now my BT Headset is the only remembered device (and sometimes, it too will disappear. Now i constantly have to re-sync my stereo. However when a re-sync is needed, i don't have to pair the devices.
On my G1, this was not an issue. So any ideas?

I have my laptop, headset, and stereo headphones paired to my phone. Haven't had any problems, they all remember fine. However, I sometimes have to disable and re-enable Bluetooth because I have a custom name for my device, and sometimes when the phone boots it forgets that it has that name and goes back to calling itself SGH-T959. I don't know if this is related... just throwing it out there.

This does help a little. Perhaps because I am still stock, I am having this issue. What ROM are you using?

I've had the problem on stock JFD, JI6, and on Bionix with JAC Voodoo kernel.

I'm having the same problem with my car's BT system. I thought it was my car till I read ur post. What happens with me, is that the car (which should connect automatically) will say that there isn't a phone available. I will then open Bluetooth settings (on my phone) and see that there are no devices listed. After cycling the BT off then on, my car will show up again, and will connect......strange

Exactly my issue. So seeing how i am not alone in the issue, does anyone know a fix or how to resolve issue? It's not a BIG problem, bnut it is annoying to have to re-sync everytime i get in my car, (or send files from my iMac to my phone).

+1 for the vibrant forgetting my bluetooth devices. I'll open my headset and I hear it say, "Ready to Pair". It's not a big deal, really-- all I have to do is turn bluetooth on, then turn it back off and all my devices repopulate. But it is an annoyance.

Ive tried that a few times, but it still yields no results for me. Any ideas.

so do we have any more suggestions from the nerd farm on how to resolve the issue?

Bluetooth woes

I've had issues with Bluetooth since I bought this phone, over a number of different ROMs and kernels. Basically it refuses to connect to my car at random. Sometime it connects fine, sometimes I have to power cycle it to get it to connect. I recently started playing with Tasker and noticed something strange. Tasker is actually registering a Bluetooth connect and immediate disconnect every 11 seconds. The Bluetooth icon never changes to blue, however.
Does this sound familiar to anyone? Is there a log I can check that will give me more details on why it's not staying connected for more than a split second?

Have you tried other bluetooth devices to your phone other than your car? If yes, then it's the phone, if not, then it's the car. If it is the car, is there a way to "update" the bluetooth drivers on it? Is it a VW or BMW?

I actually don't have any other bluetooth devices to test it with. My Galaxy Nexus connects just fine to it though. It's a Logitech Liquid Aux device.

Bluetooth Issue after May Update

I've got a strange bluetooth issue that started after the latest update. It happens with the sync in my wife's car and the HomeSpot bluetooth receiver in my car. It is mostly random, but I can count on it to happen every day immediately when I leave for work.
The phone will connect to bluetooth just fine and start playing music from google play. Then sudden the audio stream will switch from bluetooth to coming out of the phone speakers. When this happens the phone is still connected to bluetooth, just not sending the audio any longer. To fix it I have to disconnect from the bluetooth device and reconnect. It is starting to get real annoying, and I've already tried clearing my cache to no avail. I also tried turning off bluetooth in the location scanning settings and that didn't help either. Anybody have any clue?

Just had the same thing happen with my BT headset. Weird, I read this thread and said I never have issues, and then it happens...

Agree.. Also I am receiving a 'screech' noise sometimes while the music is playing..

So it looks like this is related to cast changes. When the audio starts coming through the phone instead of the car stereo the phone is still connected via bluetooth. If in google play music I stop casting and then select to start casting on my BT device again it starts working without me having to turn BT off and back on.
This is really annoying and I've sent google feedback via the play music app.

I'm also having weird Bluetooth issue. It sometimes doesn't turns off from notification screen. I've to manually go to Bluetooth settings and turn it off from there.

Bluetooth pairing issues

I'm having problems during the initial pairing of any BT device. The phone finds no BT devices at all. Turning BT off/on doesn't work. Toggling airplane mode fixes the issue for the time being and allows pairing. It's only slightly annoying since once the device is paired, it connects without a problem.
Is anyone else facing this issue? The update from this week didn't fix the issue. The phone is stock.

No issues at all. Pairs perfectly with galaxy 2 watch, car stereo, headset and home speaker system..

I don't have the same issue, but I can't seem to be able to pair the device with my car. It connects to both of my Bluetooth headphones just fine. The car name shows up in my Bluetooth devices list under pairing mode, but when I click it, nothing happens. Let me know if anyone else is having a similar problem.

I'm having the exact same issue with two 6Ts, one from T-Mobile and the other directly from OnePlus. Both are up to date with regards to firmware.
Its almost like the Bluetooth stack is crashing sometime after booting or cycling airplane mode because it works for a little while and then stops.

Same issue here.
Doesn't see some devices.
Constantly re-asks if I will share my contacts with my car.
My pixel 2 didn't have these issues with the same devices, so I know it's just the op6t.

Had this issue. Glad there was a work around. What a pain in the neck.

Same having BT issues where it loses the pairing and I have to repair device.

BT Connection Drop
I am having the same problem of connectivity dropping and then getting reconnected all of a sudden. Can anyone tell me how to fix this for now? Also, any planned upgrades in future for the same?

People, I need help. I can't pair my oneplus 6t with any Bluetooth device. Whenever I try to pair it says: couldn't pair with XXX because of incorrect PIN or passkey. I tried every possible solution I found on the internet (reset Bluetooth, reset phone, reset network settings, wipe cache, etc) and no luck. All Bluetooth devices are functional and I am able to connect them to my Samsung phone, but no luck with oneplus 6t. I am running oxygenOs 9.0.13 and none of my Bluetooth devices has the pin code. Please help, this is really frustrating ?

BT connectivity issues

Hi guys,
I have a Galaxy S8 Plus running on Oreo rooted, although I have an issue witv Bluetooth and I don't know if it's hardware or software related.
Basically, whenever I turn on Bluetooth, I can't see my paired devices, for instance I have a Gear S3 watch and whenever I turn on BT my phone cannot detect it even though it's already paired, the only way for me to connect it is by launching the Gear app and clicking on connect, and each time it asks for the pairing permission. I do also have BT earphones and the only way I can connect them is by resetting my earphones that way they can be detected by my phone.
This is so weird, does anyone else experience this issue?
Any help is appreciated. Thank you.
