[Q] Bluetooth and Android OS bugs,am I crazy?

Disclaimer: I've searched the forums day after day and have found nothing that helps me in any way.
Hey guys, I'll get right down to this:
I've got a Moto X VZW MM 32GB, initially shipped with 4.2.2 and running 4.4 as soon as I got it activated.
Everything on the Moto X works great, fluid graphics, fast app opening, battery (for the most part). But I've got a bone to pick with bluetooth, as well as Android OS.
First off, the bluetooth bugs, or what I'd like to call, The Blues.
Problems
- I have Pioneer Premier FH-P800BT, running great for the past 6 months or so. I originally had a Galaxy Nexus from VZW, with CM10.2 on it and bluetooth worked flawlessly, save for an obvious quality issue with phone calls/echo cancellation. A2DP and HSP/HFP would connect immediately as soon as the car came on. With my Moto X, HFP/HSP connects fine on powerup of the radio, but A2DP will not, and my phone shows "Connecting..." in bluetooth settings. When I first pair the phone (or re-pair), all profiles connect and audio works without a hitch. But every time after, it doesn't work that way. I can get around the issue by putting my radio in pair mode and turning on bluetooth, which essentially re-pairs the devices together, and that works. I think the biggest thing is that my radio connects HSP/HFP first, and then A2DP, and the phone is expecting both at the same time, and this causes the glitch I'm having. I haven't FR'd yet because this could be something that a FR won't fix (aka software issue that wasn't fixed by Moto).
- On all bluetooth devices with A2DP, sometimes the quality is great, sometimes it does what I like to call a "stucho" aka a stutter/echo. The best way I can explain it is if you've ever heard a record skip back and keep playing the same part, multiply that by like 100x. Or better example, for you Galaxy Nexus users (other phones too, if they do it) when your phone would freeze from being overloaded, and it ultimately crashed (non responsive to anything, screen won't come on, or maybe stuck on) and the audio get's hung. The sound does that on the Moto X, but it continues playing the track without pausing/skipping. It's extremely annoying, and mostly occurs when surfaceflinger is active (I'd assume that's what it is), as it's when anything animation-wise caused by user input occurs. I've also had the audio deteriorate in the same manner, but after it does the weird stucho effect, the audio slows down a bit, noticeable, like, listening to "We Found Love" by Rihanna sounded like a man singing it, and then it will speed up and go too fast after about a minute, and then resume normal playback. Despite completely pausing on my Galaxy Nexus, that phone never did have the audio issues this Moto X does, and it occurs on every A2DP device I've tried (BMW iDrive, Hyundai Sonata factory radio, Philips SBT series, my Pioneer headunit).
Second issue I'm having: Android OS
- I've tried ART and running Dalvik as the runtime, and on both, after weeks of running them, I notice that throughout the day, 3-4% battery drain per hour, with nothing in recent apps, wifi on, and all VZW software except for backup assistant disabled. I'm not complaining because I tend to make it to the end of the day with 2 1/2 hours SOT and and about 10% left on battery, but I'm curious as to why it's not making it any further. I don't have much installed. Dropbox, Facebook, Exchange account, Wallet, and other programs that don't run in the background (OS Monitor, Dots (game), etc). While my SOT can show 2 1/2 hours, it's only taking like 35% of the battery while Android OS shows like 20% or more, and shows CPU time around 1:45 hrs.
Any insight on either of these issues would be appreciated. I love the phone, everything else is perfect, but these 2 things are kinda irking me because I know this isn't the way the phone should be operating, moreso with the bluetooth bug.

Bump

My Bluetooth works fine on my old Motorola visor mount device...music and stuff goes through my radio.
As far as battery goes....go to the general section and read the "how's your battery life " thread. Every bit of troubleshooting and issues is already there.
Good luck!

Glad to hear that yours is working great, mine usually does. I'll also add that call quality is top notch over bluetooth, much cleaner than on my Gnex. It's just A2DP sometimes will do the above mentioned, and it's so annoying. Using the headphone jack it is fine, it's specific to bluetooth.
As for battery tips, I've tried a good portion, short of rooting the device and greenifying it. I ran my Gnex forever, and I kid you not, swapped/flashed at least 60 roms, so I know what I'm doing in terms of de-bloat and rooting and such, but if not for these bugs, I'd be happy with the phone itself.
Thanks for the tips though I'll look, but in the mean time, anybody else ever noticed what I'm talking about?

I don't have stutter/echo problems but after taking a call on it and trying to go back to music the app acts like it is playing but no music is heard. I have to cycle BT on/off or cycle the power on the adapter. This is on a car adapter, the Kinivo BTC450. The adapter was flawless with an iPhone 5s and pretty good with a nexus 5. I am hoping it is 4.4 bugs and 4.4.2 will clear it up. It is supposed to launch Feb. 1 in Europe with 4.4.2 so hopefully we'll all see an update. I'm tinkering with the idea of going back to 4.2.2 to see if it is any better.

Well, I've solved 2 of the 3 problems I was having. Android OS no longer takes over my battery, and thankfully, more people today had posted that Snapchat was a battery hog on 4.4 (or on any OS version for that matter). And I wasn't just hallucinating, considering at 50% battery, SOT was ~ 1 hr while Android OS showed like almost 2 hours of being active, and percentages were like 33-35% for SOT, and 20-25% for Android OS. So I think now that 33mins of SOT at 90% battery and Android OS only showing 5% usage, issue's resolved
Bluetooth stuttering was seemingly with all audio services on my phone, but after I tinkered, I found anything that passed through the built-in EQ was stuttering when surfaceflinger was active. And oddly enough, only with bluetooth, and not even all the time. So in short, disabling the EQ on the phone seems to have fixed the weird jerking/echo/stucho sound period. I'll test a bit further, but so far that seems to be good.
Did a bit more testing in regards to A2DP issues, and found that in a newer Sonata (2013 Limited) the factory bluetooth links to A2DP and HSP/HFP within 30 seconds and both work properly. In my car though (Sentra) with an aftermarket Pioneer headunit (model number in the 1st post) the headunit must connect in a different matter, as HSP/HFP always connects immediately but A2DP tries to connect and it fails out. I have to re-pair the phone to the headunit each time to get both to pair properly. I'll test more with this but for now, this is still a bug, hopefully 4.4.2 will fix these issues.

So disabling the audio effects in the audio menu fixed the stuttering for you? Going to give that a sit tomorrow as well as uninstalling snap chat

I can confirm that for the past 2 days, with the Audio Effects/EQ disabled, I have no stutter with audio over bluetooth, it plays much smoother now. Also, uninstalling Snapchat has 100% resolved my Android OS battery drain. I was only getting an hour and a half of SOT with 30% battery left before, and now I successfully hit 50% battery with right at 2 hours SOT, so it's definitely made a huge difference. That's with dropbox, exchange account, facebook, and a few other random apps running. Worth a shot to see if it really does it for you, but YMMV

Any resolution on this? I have the exact same problem with my Pioneer head unit. So annoying having to repair every time!

Only problem I'm having with Bluetooth in my car is that incoming phone calls break my audio connection. Instead of resuming, the audio ceases and i have to unpair and repair to get my audio back.

I am experiencing a similar bug.
Subaru Outback 2013 with Navigation (Fujitsu-10). I can pair the device just fine, but the automatic connection doesn't work at all. It will just say "Automatic connection has failed" on the navigation screen, and no indication on the phone.
That is what happens when I turn on the car when the phone has Bluetooth already enabled.
If I turn bluetooth off and back on again, it connects.
If I go into the bluetooth menu and tap CAR MULTIMEDIA, it connects.
The only thing that doesn't work is the *automatic* connection.
Like you, I previously had a Samsung Galaxy Nexus. I was running CM 10.2 and CM11 on it, both worked perfectly well with Bluetooth in the car.

If you search for "kitkat bluetooth issues" you will find multiple issues reported about different phones. In 4.4 Google went with a new BlueTooth implementation that broke compatibility with some of the devices. My Moto X DE (GSM) is at 4.2.2 and is perfectly compatible with my built-in car entertainment system, so I am probably never upgrading since downgrade from 4.4.2 is not possible.

It was actually 4.2 where Android switched from BlueZ to BlueDroid. In 4.3 and 4.4 there were significant developments to "finish" that implementation. On my Nexus, 4.2 was worthless, but 4.3 and 4.4 worked great. It's certainly possible that Motorola botched something with their upgrade to 4.4 - or maybe Motorola had their own Bluetooth stack separate from AOSP.

I don't think this is correct. See this post: http://forum.xda-developers.com/moto-x/moto-x-qa/flashed-4-4-2-partition-table-gpt-bin-t2657468/post50555443 GPT flash is non-reversible and can prevent downgrade.
Here is another quote from now deleted thread:
This is a simple chart what can and can't not be downgraded, Thanks to Dray_jr :thumbup:
the only OTA that can downgrade is 4.4 to 4.2.2 Post Cam
here is what we know right now that might make more sense
4.4 to 4.2.2 Pre Cam will Brick
4.2.2 Post Cam to 4.2.2 Pre Cam will Brick.
4.4.2 to to anything will Brick
4.4 to 4.2.2 Post Cam you are ok

Huh, that's news to me. Thanks for that link. This is what I get for thinking the Moto X would be just like a Nexus device.

To answer a few questions regarding this:
1: You most certainly CAN flash any ROM you wish to a DE Moto X, you just need to unlock the bootloader. When the BL is unlocked, it allows you to flash whatever you want. Look it up and do your homework, it's essentially a Nexus, without the AOSP out of the box.
2: The if 4.4 had so many bluetooth bugs, then why did my Gnex running AOSP 4.4 (the hacked together one that had driver bugs) work PERFECT, and I mean legit PERFECT with bluetooth on all devices I used? The point is moot with the bluetooth stack being bugged. Obviously Google tested this on MANY of their internal devices before releasing to Nexus devices and the AOSP branch. Y'all have no logic if you believe otherwise. I DO, however, agree that it's possible that Moto is using a non-standard or non-AOSP bluetooth stack, or they have modified the bluetooth config to the point where it doesn't work.
4.4.2 for the Moto X didn't fix my problem, although it supposedly did fix some bluetooth bugs. I can still use the phone with a 2013 Hyundai Sonata Limited's bluetooth, and it pairs perfectly every time. This seems to be a hardware-specific issue, as I see people with older model Pioneer/Kenwood/etc. Bluetooth 2.0 headunits having issues, as well as with some hands-free BT units too. But on newer vehicles, some radios don't have the problem. I'm gonna file another ticket with Moto and see if I can provide proof to the problem.

Guys....aside from keeping your warranty, the DE is no different than any other moto x with an unlocked bootloader. I don't know why people keep saying its any more than an x that gets a warranty.
You cannot downgrade with any less risk of bricking than any other unlocked moto x.
I hope this rumor of the dev edition being special in this regard ends quickly...before there's a tonne of "I'm bricked" threads.
No moto x is a nexus. There is no downgrading the bootloader without heavy risk. The stories you've read here about downgrading bricks WILL happen to the dev edition just like the other unlocked moto's. Mark my words.... please.

No. Downgrading is a HUGE brick risk. Trust me.
Moto x's are nothing like a nexus when it comes to the bootloaders.
Dev edition is like the rest....but you keep warranty. That's all!

Because on Verizon, it's the only one that has an unlockable bootloader. Unlocked bootloader USED to mean that you can run any code you want on it, and recover mistakes using fastboot. And unless I'm mistaken, it still means that. The GPT thing is concerning, but there's still nothing preventing executable code from being run, it's just the partition table that is different, and the old ROM images cannot be written to it.

How is that the case, though? Does fastboot stop working? Can you not re-flash a 4.4.2 image once provided by motorola? Do recovery consoles not flash? Can they no longer write to flash? And the real question - is it just because the older android images and recovery consoles do not understand GPT, or is there something actively preventing it? I know I've painted myself into a corner the last time I switched a drive to GPT and had a hard time finding a LiveCD that could mount it, but that was years ago. I'm crossing my fingers that it's only a matter of time before parted finds its way into CWM and TWRP.

Agreed. Personally, I'm disappointed with the Moto X in this regard. I'm glad to now be informed of this, and I hope others look into it themselves as well.

I can't speak for what dev edition means on other phones....but for the Moto x, Dev edition means you can unlock bootloader, same as many other models....though your warranty is still good......and once unlocked, its EXACTLY the same as any other unlocked Moto x as far as flashing rules and RISKS.
I don't claim to be an expert on precisely why and what causes a brick, but I've read more than enough on here lately to know that downgrading from 4.4.2 is playing with fire. LOL
Funny....I just went to flash a 4.2.2 rom on my Nexus 7 the other day and got an error about incompatible boot loader (I was on 4.4.2 at the time) and I remembered, crap...that's right! So I flashed the previous bootloader version....then the 4.2.2 rom. Done ...10 minutes and zero issues. LOL. Not sure why Motorola had to make things harder/different.

Back to the original topic - I took the upgrade to 4.4.2 last night:
- Disabled things like XPosed
- Re-flashed stock recovery (using fastboot)
- Applied update
- Re-flashed CWM recovery
- Re-applied root and xposed
I didn't do anything else, apart from app upgrades that happened to come in. When I got in my car this morning it immediately automatically connected. Could be a coincidence, or maybe that upgrade fixed the bug.
EDIT: I was in and out of the car probably half a dozen times today, works perfectly now, auto-connected every time!

Nexus 6 Marshmallow Bluetooth not operating correctly

I have flashed the official google images. MRA58K and MRA58R - both have the following issue:
I'll outline it logistically:
* I connect bluetooth to my 2013 Honda Accord
* When I dial a phone number from the nexus device OR using the car's bluetooth menu the bluetooth disconnects
* the phone continues to call the person
* after the person answers the phone and says hello a few times, the phone reconnects to bluetooth
* the phone call goes on as normal. At this point I have a 20% rate of failure where the phone call connects for a few minutes and then the phone just hangs up on the person randomly. The other 80% of the time the phone call goes correctly without hitch after this point.
I've found the following thread here that seems to outline my problem exactly: https://productforums.google.com/forum/#!topic/nexus/SaoZyWfkX94;context-place=forum/nexus
Add me to the list of people whose Bluetooth connectivity has suffered after upgrading from Lollipop to Marshmallow (on my Nexus 5). All was working perfectly in my 2015 Honda Accord, connecting to their HandsFreeLink software to make and receive calls. Now calls do go out, but you cannot hear the phone "ringing", and the radio comes back on again until the call is completed, when you suddenly hear the caller say "hello." Also many instances of poor call connection (unusable screeching sounds or very garbled speech). Did everything except reset to factory settings: wiped cache, reset the phone to the car's bluetooth, etc. Waiting hopefully for the 6.0.1 update to save the day….

I am also having almost the exact same issue.
I have yet to find a working solution. In the meantime, all I could do is go back to 5.1.1.
Also, M developer preview 1, 2 and 3 all work fine.

OK. I finally got it working right.
I will tell you what I did in case you want to try it, if you are comfortable flashing a CM13 alpha.
While on 5.1.1 lmy48y, I flashed CM13 Alpha cm-13.0-20151124-UNOFFICIAL found here.
And gapps found here.
I kept the 5.1.1 bootloader and radio, and have not had any issues.
I am using Elemental kernel 3.06.
And I also formatted my device to remove encryption.
So far so good. No more weird behavior on my CRV blue-tooth.
I don't think that the kernel makes a difference, but that is what I am using and have not tried with any others after getting this working combination.
Hope this helps.

6.0.1 Stock fixes bluetooth issues.
Just in case anyone is still having these issues. I just downloaded and installed stock 6.0.1 and everything is now working great.
Cheers.

I am running stock 6.0.1 and my bluetooth doesn't work. At all. Annoying.

6.0.1 introduced a slew of other Bluetooth issues. Because it links phone and BT accessory volume levels (before this they were separate,) this causes some headsets to be stuck on max volume no matter what you do. Rendered my LG HBS-730 useless.

Am getting 100% bluesleep / msm_serial_ds wakelocks on various ROMs using a pebble watch. This makes using Bluetooth and my watch unusable due to radically reduced battery. Any ideas?

True. I had not noticed the bluetooth volume bug, but it is there.

They finally fixed it in N Preview. Hopefully this rolls out as part of monthly security updates for 6.0.1 as well.

I am on N, and Since Marshmallow, i have not been able to pair in my Acura TL bluetooth. Same issue with N. Every other phone before or after has or is working well with my Acura TL. So I KNOW it's not the Vehicle, and I know it's not the phone. I can pair my Nexus 6 with a bluetooth speaker, a bluetooth headset, a NON factory bluetooth DIN radio, and a Bluetooth NON factory In vehicle hands free (GROM) without any issues. Somehow, there is a slight change that is affecting CERTAIN devices prior to marshmallow, that is present now.
I have read about activating the GPS, and trying to sync the phone to the Acura Bluetooth... this has made NO difference. Bluetooth will eventually timeout.

Bluetooth Metadata issues after Nougat Upgrade

Hi guys,
For those that have Bluetooth in your cars and use apps like SoundCloud, Pandora, etc., have you had issues with track information being displayed correctly?
Ever since I upgraded my Nexus 6 to nougat, the track information seems to be routed differently by the phones Bluetooth to my car's aftermarket Bluetooth receiver. Same has happened with my wife's Nexus 6 after she upgraded last week.
Both phones were working fine when on marshmallow using the same apps...Nothing else different other than upgrading to Nougat.
The only app that shows the metadata correctly on the main screen is the Play Music app. For all other 3rd part apps, I have to select "Channel List" and then I can see the track name. That was not the case with Marshmallow. All apps showed the metadata at the main screen where now it just displays some random numbers.
I know it's not the 3rd party music apps because they all display the metadata correctly when I have my work iPhone connected to my car.
Had the same problem on stock as well as Pure and Nitrogen. It's so frustrating because I don't have the slightest of clue on how I can go about figuring out what, if anything, has changed with the Bluetooth profile.
Any help or feedback would be greatly appreciated!

Ok first you need to understand a few things.
1. Just because it works on an Iphone doesnt mean anything when talking about android apps. They are completely different OSs as well as completely different apps. Built completely separately with different SDK
2. Just because it worked on the last update doesnt mean it will work on this.
As google play music works, that says they changed something in the 7.x update that broke the other apps. They will need to be updated to work with the change in the code.

As google play music works, that says they changed something in the 7.x update that broke the other apps. They will need to be updated to work with the change in the code.

Appreciate the feedback, thanks!
Yup... Definitely understand that iOS and Android are 2 complete different bases...I tested with the iPhone to make sure that the aftermarket Bluetooth receiver in the car was not the problem.
I do believe it's something that Google has changed and I'm starting to realize that the only option I may have is to wait and see.
One point I want to add is that the Nougat update did not break anything when it comes to connecting to my wife's Acura with built in Bluetooth. The track info continues to work fine..
I was hoping someone with more in depth knowledge of the Android systems maybe be able to chime in on what could have changed...I know the 3rd party apps i use have gone through multiple updates since Nougat came out so if they were gonna update something due to compatibility with Nougat, it would've happened already.

Hi guys,
For those that have Bluetooth in your cars and use apps like SoundCloud, Pandora, etc., have you had issues with track information being displayed correctly?
Ever since I upgraded my Nexus 6 to nougat, the track information seems to be routed differently by the phones Bluetooth to my car's aftermarket Bluetooth receiver. Same has happened with my wife's Nexus 6 after she upgraded last week.
Both phones were working fine when on marshmallow using the same apps...Nothing else different other than upgrading to Nougat.
The only app that shows the metadata correctly on the main screen is the Play Music app. For all other 3rd part apps, I have to select "Channel List" and then I can see the track name. That was not the case with Marshmallow. All apps showed the metadata at the main screen where now it just displays some random numbers.
I know it's not the 3rd party music apps because they all display the metadata correctly when I have my work iPhone connected to my car.
Had the same problem on stock as well as Pure and Nitrogen. It's so frustrating because I don't have the slightest of clue on how I can go about figuring out what, if anything, has changed with the Bluetooth profile.
Any help or feedback would be greatly appreciated!

Exactly same issue here in my '15 Civic Si with Shamu, Victara, and Titan, Bluetooth metadata breaks after the first pairing/connection. Once Bluetooth is interrupted, either by shutting off car or disconnecting Bluetooth, metadata never displays again until I either clean flash ROM anew or delete the bluedroid folder contents and do the whole unpair and re-pair both audio device. Quite a pain of a workaround, and it doesn't stick either, breaks as soon as Bluetooth is interrupted again.
Since you're on Shamu, I can recommend Cyanide ROM and SIX ROM, also Pure Nexus (not sure why yours didn't work with it), I've tested a few updates of each of the three ROMs, and Bluetooth metadata worked fine. Nitrogen never worked for me either. AICP, CM, LOS, Resurrection Remix, Dirty Unicorns, Emotion OS, all break on this feature for now. Not sure how Google's own OS is running in this department, but I've seen quite a number of complaints on this issue with the 5x, 6p, both pixels, but not so much with Shamu. I've not ran Google's nougat since developer preview 5 of 7.0, and back then it was working, can definitely confirm. I just hopped on the custom ROM train ever since DU released their flavor of Nougat, and just can't or want to go back to stock vendor OS. But do try out Cyanide and SIX ROMs, they both worked flawlessly on this device. Both are packed with extra goodies too. If battery is more important, go with SIX ROM, it's by far the most fine tuned nougat ROM I've tested. You won't find it on XDA, look for it on G+ under "Frankie T (R3DS)" community. It's posted with all the direct links for proper installation. Cyanide is another amazing ROM, also another fine tuned ROM, comes with built in black theme, and good battery life (if you set the governor to interactiveX), but really smooth experience overall. SIX, by the way, uses Pure Nexus as a base platform, so just a heads up there. Personally I've used the last two pure Nexus ROM updates and had zero issues with song data displaying via Bluetooth. Make sure you clean flash the ROM, wipe dalvik cache, cache, date, and system. Leave the internal storage unchecked. If the issue persists, then backup your internal storage files/folders to an external drive/device and format the whole internal storage of your Shamu, then throw everything back on and try clean flashing, pure Nexus should work thereafter. I've even restored it as a nandroid backup a few times and had no issues. SIX ROM is pretty much a refined Pure Nexus with extra features. Give these a shot, well worth it. Let me know how it goes for you.

Wow! Thank you for the detailed feedback! Does your Si have factory nav?
Anyway, I can't tell you how many things I've tried to get this thing figured out...I also have active communication with the manufacturer of the Bluetooth unit to see if we can troubleshoot the issue..So far nothing.
This is the first time I'm hearing of SIX ROM so I'm gonna do some reading and then flash it later on in the week. I'll reply back with updates.
Thanks again!

Happy to help. No my Si doesn't have the navigation option, I just use my Shamu for that. I've finally got the attention of AICP moderator and developer at AICP G+ community, so it's looking like the Bluetooth metadata issue is a CM/LOS issue so far, they're going to look into it. I captured a logcat and pictures which are posted there under bugs+logcat. It's under AICP G+ community if you want to look at it, posted under my main Google account as Andrey K, you can check it out here: https://plus.google.com/112643646080294190790/posts/4FRbAonGT55.
As for you never hearing about SIX ROM, that's because the dev doesn't participate on XDA forums. It's a really stable nougat ROM all around, and now supports phh's root, which if paired with Magisk app, allows to hide root access from apps like Android pay and Pokemon go.
The most a manufacturer would offer is to replace the device, possibly for a fee, that won't solve your problem. Most nougat ROMs are currently experiencing this bug. Cyanide, SIX, and Pure Nexus do not have this problem, at least not on Shamu.

anyone ever come across a fix for this?

Nah, still struggling with it...I keep hoping that a new Android update will fix it but so far no luck. It used to work fine for me in Lollipop but nothing since I've upgraded to Nougat. I'm on Nexus 6. Wife has a pixel XL and had the same issue when she was on Nougat so it's not the phone. She did get the Oreo update this week so I'll try again to see if it works. If not, then this must be a compatibility issue that the adapter manufacturer may need to look at...
The annoying thing is that the metadata transfer is fine when using my work iPhone. But I hate the iPhone/Apple so I only touch that thing when I absolutely have to (work calls, work emails, etc)

Any solutions so far?
My S2 worked perfect with the Civic (only it did not import the whole phonebook). With S8 I have the whole phonebook but no metadata on tracks (still plays and controls work)

Bluetooth is driving me nuts! Need help please.....

Hello everyone,
I'm having major issues with my Nexus 6 over the past 3 weeks or so.
I've had this phone for almost 2 full years now and love it, however, over the past 3 weeks the bluetooth function keeps turning off when I reboot my phone every night.
It NEVER did this in the past 2 years. Only the last 3 weeks. It seems to be some sort of battery saving feature, I would presume.
What drives me nuts, is I always like to have my bluetooth on, since I get in my truck and it auto connects to my GMC IntelliLink (which is also a problem).
So does anyone know why, all of a sudden, after reboot, bluetooth defaults to off and I have to manually turn it on every time? My Nexus 6 has been flawless up until now.
I've looked everywhere for an "auto start" option for bluetooth, but cannot find one. I have ZERO idea how this happened all of a sudden. I've been running the same ROM since last February with no problems (ROM screenshot attached).
As for my bluetooth truck problem, that started today. All of a sudden "phone audio" will not let me select the box, only "Media Audio" and "Contact Sharing" boxes are selected. Thus my Pandora plays over bluetooth, but my phone calls will not.
Also my Bose Quiet Comfort headphones used to connect perfectly with my Nexus 6, now I'm at work and I notice if I turn the headphones off, then come back and turn on, it'll say "connected to Nexus 6", but the sound is playing through the phone instead of the headphones, even though the bluetooth connection has been established.
Again, this is only over the last few weeks.
Any help would be greatly appreciated.
I'm willing to update to a new ROM or do a wipe, I just tend to live by the motto "if it ain't broke, don't fix it"........ except now it is broke and I want to fix it.
Thank you-

Paste a logcat here. A dev could take a look and help you out.
or
Backup your stuff and do a clean install of a new pure nexus or whatever rom, if it's still present after that, maybe it's just your battery starts to dying after 2 years.
Edit: I'm using crdroid as daily driver and have no bt issues

So glad you posted this, I'm having the same issue! After either a restart or just a period of time my Bluetooth turns to disabled. It is especially frustrating as I have it connected to my watch, which allows me to unlock with smart unlock. When the Bluetooth is disabled, I have to punch my pin in.
I am on stock 7.1.1, February update. I am rooted and flashed the Echo Permissions Fix. I was going to flash stock again this morning, but decided to check here first for a solution. I am just happy to know that it's not just me.
That being said, like @MVLJR, I recently flashed PureNexus ROM and that for me is when this began. I flashed back to stock via flashall, but it has not stopped the problem. Could it be a PureNexus thing?

As we have PureNexus somewhat in common, I am doing some searching on that page. I had previously posted there about it, but I don't think I ever got a response. Someone mentions it on Page 3417, I'll keep reading to see if I find a solution.
My post, by the way, is on page 3420.

I had a problem like this on Pure Nexus and flashed back to stock (N6F26R) to see if the problem goes away...
Previously on stock (release before N6F26R) and never had an issue. I use Bluetooth with a watch, fitness band and sometimes my Wife's Ford...

@muiriddin, did the problem go away for you? Because I flashed back to stock and the problem persists.

@MVLJR, I suspect that the problem is Android Wear 2.0 on our phones. Do you have a smart watch?
Edit: On the PureNexus forum, people without Android Wear are also experiencing it. So back to the drawing board. I still do not think it is your ROM.

Reading this thread reminded me of something I dealt with a while back, I don't know if this will do it for all of you, but I figured I'd post this. I screenshotted a reddit thread that fixed the problem for me. I can't remember if what I experienced was the same as all of you, and I am not having the problem now. But I hope this helps. Please see the attached screenshot.

I don't have an android watch, but I do have a fitbit and don't have any problems with it.
A little update, I cleared my Bluetooth cache and changed the name of my device, which seems to have helped.
My Bose headphones now autoconnect like before.
However, my Bluetooth still shuts off after reboot. My GMC Intellilink still won't let me select "Phone Audio" either.
I think I'm going to flash a new ROM this week, which sucks because I've grown attached to the Pure Nexus ROM.
Can someone show me how to post a logcat?
Thanks

This (and similar) bluetooth issues have been reported on the nougat product pages. It's not unique to PureNexus or the Nexus 6.
Reports are that 7.1.2 (beta) fixes the issue on devices that have access to it. Hopefully a fix comes down the pipe for the Nexus 6 as well, as I have some of the same issues.
Similar posts can be found on the nexus6 and googlepixel subreddit pages.

My question is, what prompted this?
I've had the same ROM for a year, no OTA updates. Had to be an app update, correct?
No other way to explain how it worked for a year, now problems all over the place

You've been using the same ROM, but updating the version of the ROM, correct?
And the ROM updates are based on updates made to Android by Google.
So if a bug makes it into Nougat, it will (generally) make it into the modified ROM as well.

Incorrect, I've been on the same version of Pure Nexus since last February, screen shot in original post

I take it the fix I posted didn't help? I was really hopeful that it was the same issue and that would fix it up.

I haven't tried it yet, at work right now, I'll give it a shot later.
I'll update my findings.
Thanks

Will keep my fingers crossed. One thing to note, when doing that fix, it *will* wipe your bluetooth auto-pair devices. So don't fret if nothing automatically connects afterwards. You have to repair everything.

It is not a new problem, there are many threads in the Q&A forum if you search. Here is one:
https://forum.xda-developers.com/nexus-6/help/bluetooth-off-reason-pattern-t3435436
(there are more links and suggested workarounds in that thread from me)
That said, installing the AW 2.0 DP 4 totally solved my BT disconnects from my Huawei watch and LG stereo headset.
The changelog on the latest Huawei AW 1.5 mentions BT issues, but I have not tried it.
AW 2.0 official is supposed to start rolling out OTA tomorrow, so we shall see. (finners crossed tite )
I'm on Jan 21 PN 7.1.1, latest AW app. I have no suggestions of those having issues with no Android Wear, but there are threads here with suggested workarounds that solved this for many of us before, you might want to check them.

@Morpherios and @MVLJR
I don't know if it's of any note, but one of the actions I attempted in trying to fix mine was to reset all network settings via the "More" option in Wireless & Networks settings (I backed up wifi settings in advance). That's essentially a nuking of all network settings, including wifi, cell, and bluetooth. It did not resolve my issue.
@Pkt_Lnt seems to be indicating that with updated AW on his watch, the disconnects are not happening. How the software on the watch (as opposed to the AW app on the phone) would be causing bluetooth to crash, I'm not sure. But it's not outside the realm of possibility.

My words were / are different than that:
AW 2.0 DP 4 totally solved my BT disconnects
That means they do NOT happen any more, since Dec 11, 2016 when I installed AW OS 2.0 DP4 was released and I installed it on my watch. Not. One. Disconnect. None. Nada. Zero. Zip. Zilch. Nein.. :victory:
BT devices communicate both directions. The watch CAN control the phone, and was turning off BT. It was obvious when it happened, when my headphones prompt "Out of Range, trying to connect" (I came to hate hate that voice prompt )
I would immediately open the AW app on the phone at disconnect and was prompted to turn on BT because it was off.

@Pkt_Lnt I completely agree that it BT communication is two-way...I stated that it's not outside the realm of possibility because there are a number of factors that could do it, including the phone receiving a message it simply doesn't know what to do with and causing a fault. This could explain my bluetooth share crash messages that I received on occasion.
It's encouraging to know that it's fixed with AW 2.0 for you. I hope it carries through to me when I get the update. If the OTA doesn't drop tomorrow, I may have to flash the DP as well.

Bluetooth media - unknown on Sync

Not sure if this is a nougat issue or a Franco kernel issue, but when using Ford MySync or whatever it's called I show unknown artist unknown song as my display on my car audio screen. This same configuration was working fine on MM with France r10 but once I moved to Nougat it's been unable to give me artist and song info.
I've cleared cache, reinstalled apps, removed and added my car back as an audio source all with no luck in resolving. I have also looked through the Franco thread so I don't think it's related to his stuff. I am also updated to the latest kernel he released, no fix there. Not really anything else special on my device except magisk for root.
Is anyone else having this issue? It's kind of driving me crazy. I almost want to revert to factory and see if that changes anything but don't want to re-root etc.
I have searched this forum and others for a fix but everyone says it's app specific, which mine is not. It won't work in sound cloud, play music, YouTube, or any other media apps it was known working in before the update.

I have the same issue in my Mustang...

Are you rooted or using any non stock kernel? If rooted, what method? If kernel which? Thank a for the reply. Its nice to know it's not just me.

Rooted yes. I've tried stock kernel and Franco.

Took out my wife's 2015 explorer today and it has the same problems. I wonder if 4.10 will fix it? I'm holding off for a while before taking it...

I had the same problems with my car ( VW Passat 2014). I have the Sony Xperia ZX and HTC 10 and no problems with Bluetooth. I am using original rom and Nougat. It seems the is only Oneplus phones.

I've tried 4.10 and also now Lineage and it doesn't fix it on any of them. I'm guessing its firmware related then.

I'm having trouble connecting media on my kia!! Can receive calls but no media! Wtf tried to enable it and didn't work

I believe someone said it's OOS 4.0.3+ so 4.0.2 was fine. I can confirm because I experienced this after updating to 4.0.3.
This bug is actually a pretty big peeve of mine. I'm considering going back to 4.0.2 because of it

7.0 update fixed this for me but when I tired the 7.1.1 update it broke it again and also added a noticialbe lag when using the controls on in my car. I have since reverted back to using the 7.0 software.

It does not work on mine, unfortunately. It DID work for a day or two though.

I'm running daily Lineage OS using default kernel (usually Fusion kernel, however not right now since it's not updated for latest source) and working beautifully with my Volvo Sensus Connect, both bluetooth internet connection for car and Bluetooth audio with audio track text working. So probably some Ford mumbo jumbo. ?
