[Q] bluetooth with car stereo problems, you guessed it

Okay, so lots of people have problems with their bluetooth. I am too. I have a JVC KW-XR810 car stereo and the bluetooth keeps shutting down on one or the other. My questions are:
Does anyone else have this stereo and problem? If so, whats the situation?
Is there a ROM that works flawlessly (or close to) with the bluetooth?
Its odd though, that my headset works perfectly and I didn't have many problems with another stereo I've used. Makes me wonder if its the stereo or the phone. Still, many others have bluetooth problems with this phone...
Thanks for any responses.
Stock Froyo
Rooted
One click lag fix

My last 3 phones (including this one) have all worked flawlessly with my Sony MEX-BT3700 head unit. Phone calls, BT dialing, streaming music, all work perfectly.

Yep, same here - AT&T replaced my Captivate under warranty about 2 or 3 weeks ago due to the random shut-down issue. Took the new one home, installed Froyo, and rooted it. Everything works well, except lately I've been getting frequent bluetooth disconnects from my car stereo (Pioneer AVIC-X920BT).
The usual pattern seems to be it's good for about one call, and then shortly after ending that call, I notice that they are no longer connected. I usually turn off BT on the phone (seems to take a while to terminate) and then turn it back on, but it will usually only be good for a single call. It's been frustrating, and I'm leaning toward the problem being on the phone side, since that's where there have been recent changes.

Must be a problem with Stock Froyo. Glad I'm not using it.

I've had this issue with certain roms I was running. I have a Kenwood KDC-X993. So far on CM7 it stayed connected.

i have the same (or similar) problem with my OEM headunit on a VW Golf. BT randomly disconnects but my music (pandora) still plays through the BT stereo, unless I stop it. Then its completely disconnected and I'll have to reconnect the phone to the car.
annoying but I just deal with it.

I'm running Paragon 6 and have a Dual head unit. I haven't had any disconnect issues, my problem is the crappy Pandora app.

Same here, I have a Parrot mki system in my car, but I found a workaround that I hope works for you too:
Unpair with the device, and when you re-pair it, when it asks you to synchronize contacts, do not let it. It will bug you every time it connects, but just ignore the requests.
I haven't had a single disconnect since doing this weeks ago.

I've read about the contacts request from other users but it doesn't happen with mine. Another thing, when I lose the connection and I turn off bt one the phone out shuts off. Completely. Pushing the power button does nothing. Holding the volume up and power buttons together for a few seconds seems to restart it but theres no animation. Just the lock screen, media scanner, etc. Maybe its restarting on its own and the button pushing has nothing to do with it. Also, I listened to my bt headset for hours last night with no probs at alI. Idk. Is bt different for head units? I thought it all used the same protocals.
So it seems that its not my head unit, but the phone. Are there any good solutions for us?

My head unit never asks to download contacts. Could it be that some do because they store that info in order to identify and announce incoming calls? That would mean there's more going on than just a simple BT connection.

Yeah. One post I read said something about it using a data connection the hu for contacts. I have no idea what he was talking about though.

My head unit have the ability to sync contacts. When I first paired it, the phone asks me for permission and there's a check box to always allow.

The only purpose I can see for this is if the head unit has an integrated nav system. That would allow you to bring up a contact as a nav target independent of the phone.

Okay, gettinging back to my original questions. So far we've established that this is endemic to the captivate, mostly. There have been two replies saying that cm7 and paragon 6 have stable bt connections with head units. I read in another post that axura works as well. This is so frustrating that I'm just about willng to learn how to flash this thing.

We have? My first post says I have zero issues with this on my head unit with my phone on Eclair, Froyo and now Andromeda. If it is a phone issue mine is not suffering from it. Sounds more like it has something to do with head units that store contact data. Mine apparently doesn't.

Hmmm.
Yet in your second post you posited that it must be a Froyo issue.
Regardless of whether it is the phone or OS, a lot of Captivate owners seem to have bt issues of one kind or another with various devices. Maybe this is just a bt issue in general that everyone deals with (not just Captivate owners) and I'm just being sensitive because I haven't had much bt exposure.
Any help is appreciated here. I'm just looking for suggestions on what to do short of buying a new phone or head unit. It would be great if other users experiencing this problem would benefit from the discussion as well.
So far it appears that flashing a different ROM may be a solution but which one? Is there any way to change only the bt stack?

Sorry if that sounded short, but I'm REALLY frustrated with this.
My hu will store contacts as most do these days, but it doesn't ask for them. I don't think the problem is related to the contacts. I guess its just a random incompatibility thing.

I said it "might" be a problem with stock Froyo. I didn't see it the 3 days I was running it and my current ROM is Froyo-based and working without issue. The only other variable I can see is that others posting problems have reported having to deny access to contacts, something my head unit never asks for, in order to get it to work. That would appear to indicate the difference is in the head units and not the phones, but unless I could connect to one of these other head units to verify, I'm only guessing. Sorry.

i notice that if I toggle the bluetooth on my phone right before connecting it to my car, it works flawlessly

Installed a Kenwood X994 and had all kinds of issues with BT. Worked for awhile but would never auto connect. Only vehicle and area where I had BT issues. I realized it was due to the downloading of contacts at every connect. sometimes it would download than immediately disconnect. frustrating. Was on serendipity, Tried a native Cappy ROM, Cognition and now Phoenix..
The unit has the Parrot system in it so it should be ok. Finally decided to update the Firmware on the HU. So far so good. I like the contact download so I don't need to use the phone at all to make a call. Receiving calls is no problem.
Will test further tomorrow.
BTW I have a BT Garmin mounted in the truck and used it before getting the head unit. no problems connecting. The only issue with that was a delay between pressing the call button and the call being made. Hanging up was an issue as well.

Bluetooth Issue

So I paired the One with my QED uPlay at home and I'm having issues. The phone has to literally be 30cm away from the receiver or the audio will start getting distorted until it eventually cuts off. I have two uPlays, issue exists on both so its not tbe receiver. Also my iPhone 4s has no issues either. I was hoping the One had better audio than the iPhone since it has aptx, but its quite the opposite. Has anyone tried bluetooth music streaming? Is it just a faulty phone?

Bluetooth and Wi-Fi both use the 2.4GHz channel. Asus had issues with the Prime because of its all-aluminum design where they had to greatly amplify the Wi-Fi signal and use diversity antennas to get through it. HTC uses the latter on the One. When used together, the Wi-Fi signal can overpower and interfere with the BT signal. Try turning off Wi-Fi and see if your connection quality changes. You're the first one to mention a BT issue so it could be unique to your device. Time will tell.

I have had a problem with bt connecting to my car (audi a1) I can hear the call but the other end cannot hear me. Going to delete connection and try again tomorrow.

Thanks for the replies. I switched off WIFI, re-paired the device and bluetooth started working perfectly, so it makes sense it was interference. Strange thing is I turned WIFI back on and bluetooth was still working fine. I'll do further tests in my car tomorrow see how it goes. If I'm not convinced I'll just get the phone replaced.

I have also had issues with bluetooth paired to my hands free car kit. Issues have surfaced when streaming music and also when making audio calls via bluetooth.

The One X had a similar issue:
http://forum.xda-developers.com/showthread.php?t=1688538
It could be that when I was first trying the WIFI antenna was stuck on high power, which caused the interference, but when I reset the WIFI it reduced its power and no longer interfered with the BT. I have changed the WIFI at home to run at 5 GHZ, but work still runs on 2.4.

Apparently 1.29.709.4 has been officially released in Taiwan by HTC, so it shouldn't be long before the update arrives to the rest of us (hopefully).

got the same issue...some times I got no lags in audio streaming, but sometimes they are there...until it (maybe) will be fixed I'm using a widget, my cousin has coded for me yesterday . Quite simple solution. If I press the button, wifi turns off and bt turns on...works fine for me, so far

[Q] Unlocked Nexus 6 - Bluetooth not connecting / Discoverable

Hi - new here on the site. Thanks in advance for any help and or advice.
I just picked up an NIB unlocked N6 off swappa loaded my sim from my Droid Turbo and everything is going good EXCEPT for the bluetooth. I have the latest Lollipop update and still having issues.
The phone does not sync with any of my bluetooth devices. It's not even "discoverable". I performed some of the troubleshooting methods; clearing cache, factory reset, etc.... and still no luck.
The seller on swappa said it may be because it's on CDMA (Verizon). But that doesn't make sense to me??
Any help would be greatly appreciated!!

@Motivated1,
There is no such thing as a "Verizon" CDMA version. They are all the same. So when you go to Setti ngs/Bluetooth and enable it, it's not visible to other decides, and it doesn't discover other devices?

Thank you for the clarification Cam30era.
Yes, that is correct. I'll turn on the bluetooth toggle and it's not discoverable nor does it discover my BT devices. I tried to pair it with my Bose Colorsound speaker, my Droid Turbo, and some bluetooth headphones...all unsuccessful.

I have had a new Nexus 6 from the Play Store. for 3 days (Activated on Sprint, but I think that is irrelevant.) I am running 5.1.1, build LMY47Z.
My one issue is that the N6 Bluetooth, which I have successfully paired with my 2012 Subaru Forester, does not automatically connect. Also, sometimes it will connect to the car, but only for audio, not for phone functionality.
I usually have to fiddle with it to force a good connection. The easiest method I have found is to toggle Bluetooth on/off on the Nexus. It sometimes takes several attempts.

Thanks boomerbubba for the response.
So, I took it to a friend of mine with a moto watch and a Note 4, the N6 connected with both of them instantly. I went home and tried to pair it with my Bose Color Soundlink and once again was unsuccessful. Since I knew the bluetooth had the capability of working, I just messed around with the speaker, holding down the bluetooth button for several seconds, turning it off and on, toggling my N6 bluetooth, and sure enough it worked!!!
So I tried to pair it up with my Droid Turbo and that worked as well.
So I really don't know what the actual problem was...maybe just a finicky unit. But all is good now!

In my experience with my previous phone (a Galaxy S4), and the same car, the Bluetooth discovery "just worked" automatically. Once I had the initial pairing set up, I never had to do anything but bring the phone into the car and it connected.
So IMHO, this flaky behavior is a bug with the Nexus 6 -- or with the LMY47Z build of Android Lollipop.

I now attribute this to pilot error. I must have screwed up the initial pairings between my car and my Nexus 6. I deleted those pairings and redid them. Now my phone connects automatically when I start the car.
So, in the words of the late, great Gilda Radner on SNL: "Never mind."

I have the same problem. PITA!

My new (10 Dec 2015) 6P will not discover any of my Bluetooth device, must less connect

Bluetooth Issues...

I use BT at home daily for listening to music and netcasts. I have a couple of different BT speakers as well as the awesome Panasonic Link-to-Cell phone system for those who have dropped their home hard-wired phone lines. I also use BT constantly when I am in my car.
With my LG G2, BT connection was seamless and immediate, all the time, for years now. It connected to multiple devices as soon as I walked in the door and with my car audio as soon as I started my car.
With the N5, it always needs to be re-paired manually - especially at home where there are two devices waiting to pair with it as soon as I come home. It'll pair with the Panasonic phone, but when I select a speaker, the N5 disconnects from the Panasonic and then I have to re-pair with it. It will work once I spend a moment managing connections. In the car it often pares immediately, but sometimes not.
Another observation is that the N5's BT range is short, and it will drop if a line-of-sight gets interrupted momentarily.
In an attempt to fix, I have wiped the cache for both Bluetooth apps that come with the VZW N5 - that didn't help. Then, I wiped the system cache, also no dice. I wonder if this is carrier-dependent (I am on VZW) or something to do with older BT devices and the newer BT protocol that the N5 uses. I've read that the N4 has similar BT issues.
Overall, it's usable, but not as good as my old G2. Anyone else have these issues? Fixes??

This issue persists to this day. I can accommodate it with some manual intervention when I want to connect to my BT speakers.
Looking to get a BT 4.x speaker to see if it's just a BT version issue.

I only use Bluetooth in my car and I haven't had any issues whatsoever. Always connects as soon as I start the car and never drops the connection or anything. It syncs my contacts and everything just fine as well. I don't use Smart Lock however. Maybe try turning that off?

I think that's the case. For some reason samsung's 4.1 Bluetooth protocol is not backwards compatible. Ever since the s4 Bluetooth meta data has stopped working in my 2012 Mazda. Works fine with my N5 (nexus 5) and my LG G4. If I had to bet I think that's the issue with you. I could be wrong. Just thought I'd share.

Note 5 always works with my car, does not drop or anything but it has an unstable connection to my samsung gear circle headphones. I believe it is the 5.1.1 update, because they work with my wife's note 3 just fine and they used to work fine before the 5.1.1 update.

Did you ever resolve your issue? looks like some are successful after getting their device replaced and others are not and say the problem comes back. All seems to be related to the 5.1.1 update..

Bluetooth and Note 5, horrible combination

Thanks for writing. I found out that if I disable wifi, it connects a little better, though not as good as my wife's phone, Note 3 (my previous phone)
I tried to find ways to change the frequency it connects, but google was not helpful. Maybe some of the experts here could be helpful, I do not know.
Anyways, I tried to connect to our smart bulb yesterday. It would pair, but would never connect, wifi or not. On the other hand, the Note 3 connected to it immediately.
They keep updating the gear circle software but it is the phone fault, since gear circle is able to connect to my laptop from even another floor!

It's not the BT device... I have terrible luck with expensive purchases and my note 5 was no exception. I upgraded from a galaxy S relay (love keyboards) and about 1 month later my Bluetooth stopped working from all through my house to needing a DIRECT line of sight and max range of about 2 feet. Netflix, hulu, audible all pretty much useless with this issue.
I returned it and got a new one (not referbished) and I noticed a slight lag in key strokes. About 2 weeks go by and the bottom half of my screen is going haywire. Trying to scroll a Web page and it would click everywhere. Typing like I am now would result in 100s of extra letters I was never close to pressing. I returned it and got a referbished one and same thing... my 4th one which I'm using to type this just started doing the Bluetooth thing and I'm so mad.
It's not the Bluetooth device because I tried my old Plantronics I used for 5 years, my new Plantronics, my car, and these weird speakers that have water pumps in them and the issue was the same. I love this phone but it seems to hate me...

Quick question, do you have android 5.1.1 or 6? I still have 5.1.1 and thats when it started with the problems. It was all fine and dandy with android 5.0.
My wife has a Note 3 with 5.0 and the same headphones are just fine with it.
I have been waiting for android 6 to see if it works out.

My Note 5 upgraded itself to Android 6.0 and all my bluetooth problems are solved magically. I cannot believe how they can manage to screw up things for so many months and we have to wait for the new OS to have it solved. For Samsung Gear Circle none the less. I know I am not buying bluetooth watches or anything in case they screw up bluetooth again in an "update".

Nokia 8 Bluetooth unusable with Airpods. Anyone else?

Just to open with this - I really like this phone and have been enjoying using it. Aside from the fairly poor WiFi range and the flaky NFC it is otherwise a really nice phone. There's just one other issue I have which is extremely frustrating:
I can't use it with my Airpods. Or at least, I can connect it but at some point the sound will crackle and cut off. If I wait it will occasionally crackle and come back on again but will cut in and out in a way that would drive anyone mad. I've tried fiddling with Bluetooth settings in developer options but it doesn't seem to make any difference. I've even tried a factory reset.
The Airpods work absolutely perfectly with every other device - no issues with the iPhone (expectedly) nor the S8, G6 or even my laptop. I can't 100% rule out a fault with the Airpods but given these facts it seems highly unlikely.
I wondered if anyone else used Airpods and had experienced issues and found a solution.
Not too interested if you've had no issues with your device, nor what you think of Airpods - I just want to see if I can get to the bottom of this, or the Nokia will have to go back.
Many thanks

Similar problem
Got a similar problem with my apt-x receiver.
Every few minutes the connection drops for a very short time.
The airpods don't support apt-x, but maybe it's the same problem.
My receiver shows a connection via apt-x, , but you can't find any apt-x support in the Nokia 8 specs.
But I had no problems with a friends portable speaker (non-apt-x).
I went back to cables

I’m wondering if the Nokia 8 just has rubbish connectivity, generally. If the Bluetooth chip is part of the WiFi chip then this would figure as it has the worst WiFi connectivity I’ve seen in recent years

Are you running Nougat or Oreo? From what I've heard, a lot of the bluetooth issues have been fixed in Oreo.

I wonder if yours is wonky, my Wi-Fi is excellent and i get get 75Mbit down 19Mbit up over 5Ghz through 2 brick walls, a floor up and at the opposite end of the house, i have not missed any payments using contactless via NFC and Bluetooth works fine via an Anker Bluetooth speaker and my JBL Bluetooth headphones.

Sorry for digging an old thread, but I still have the same problem even after a bunch of software updates.
My issue with the AirPods is that they do not work after they connect. I take them out of the case, they connect (as expected), but as soon as I start playing something the music/video pauses and the sound switches to speaker (if I press play again it plays out loud). To make them work I need to go to bluetooth settings, disconnect them and connect them again. Then they will work almost flawlessy (minor intrerruption from time to time).
I have no issue with other BT speakers. I also use the AirPods with an iPad and laptop and no issues there.
My Nokia 8 software is up to date. AirPods firmware the same (checked on the iPad).
I tried re-pairing after each software update. I tried changin BT settings (absolute volume - dev settings; contact sharing and HD Audio: AAC) but no improvements.
Any ideas what else can I try?

Search for Oreo and Bluetooth problems. It seams to be a general issue for this Android Version. I have problems connecting my Phone with the car, too.
