Right after the DP5 installation, I had to unpair the phone and car (2016 Mazda) because the phone would never connect. It was no where near as easy as that sounds, took me the better part of 30 minutes because of repeated "unknown errors" coming from the car.
The phone paired up just fine but I still have frequent and completely unexplained dropouts on literally every Bluetooth device I have (headphones, Moto 360, car and the list goes on). So far this has been the absolute worst of the previews for BT that I have ever seen.
But then, if you read around here, it sounds like there were a lot of these that had flaky BT hardware. Have not exchanged mine, but that has certainly been my experience since I bought this back in December.

I have no issues with Bluetooth and the latest DP. I have my phone connected to a Kenwood deck.

I wonder if I have flaky BT hardware? Mine was a launch phone and it has worked perfectly in my Toyota since day 1. However I've recently bought a fitbit type band and with that application (veryfit 2.0) installed and connected to the band then if I make a call in car it drops the BT after about 30 seconds with an error message on screen saying 'corrupted probe message'. I can manually reconnect the call (it's still active on the phone) but after another 30 seconds or so it repeats the cycle. Have upgraded to Nougat Dev Preview NPD90G but still the same. Removing the app and its binding (it binds in the app not the phones BT devices in settings) and rebooting the phone resolves the issue. Tried again with a proper fitbit and the issue is identical.
I will RMA it to see if I get another one that works. Now to figure out how to put it back to stock marshmallow. gulp.

I had this same issue, I flashed the system file again and wiped the cache and dalvik. It seems to be ok now.

Check this solution. Pair with '0000' worked for me.

Since switching from my Nexus 5 with 6.0.1 to a Nexus 6P with 7.0 I am also suffering from bluetooth issues. Pairing itself is not a problem but the connection sometimes drops, controls in my car don't work properly, remaining track time is not shown, etc. Haven't even tried to make calls yet. If I can't find a solution I'll probably be going back to 6.0.1.
The proposed '0000' solution is not working for me as I cannot change the PIN on my Seat Leon (2016). The PIN is autogenerated and shown on both displays to be confirmed upon pairing.
Has anybody tried flashing the latest 6.0.1 radio image and use it with a 7.0 system?

Bluetooth Connection Issue -- Car Stereo

Hello,
does anyone else has issues connecting to their car Bluetooth device? I can connect to other phones and transfer files. I can also connect to a couple of Bluetooth speakers, but when I am in my car, my phone does not see my device.
I am running Validus Release 13.7 on a Moto G4 Plus (1644).
Bluetooth works fine on Stock MM.

No problem on various cars since cm14.1, Los 14. 1 official and Los 14.1 oms. Try one of this to check if it works.

Thanks strongst.
I wanted to try Los14.1 OMS, but on the OP, it says that BT file transfer is not working.
I transfer a lot of files to and from my PC. Does this work for you?

You may also wish to clear your Bluetooth configuration files - https://forum.xda-developers.com/showpost.php?p=70962694&postcount=906

Thank you Sir! I cleared the files. I just need to get off work and try it out again. Will post an update as soon as I get the results.

I works now. I reset my BT settings on my device after deleting the files mentioned above.
Thanks for your assistance.

Bluetooth pairing issues on 7.x

Hi all,
Since upgrading to Android 7.x, I've had problems connecting my phone to other Bluetooth devices, particularly my car heading it for hands-free. The headunit in one car works fine, the other car keeps connecting and disconnecting after about 1-2seconds in a continual loop. Before 7.x it was connecting fine. Even now my phone makes the notification sound of connecting when I'm in that car even when I choose 'forget this device' on both hu and phone, only way to stop the notifications is to turn bt off.
I've googled​ and found it's quite a common issue, but yet to find a solution. I joined the beta program and update everytime but yet to fix it.
My question is, will this problem be fixed if I install a custom rom like PureNexus or is it a flaw in 7.x affecting every rom? If that is the case, is it possible to downgrade to 6.x? I really want to be able to connect to my hu with hands free again, it's been months now with no luck!

Hello,
Backup your data's and try to factory reset.
You can install a custom ROM, but I guess it doesn't fix drivers issues which are closed sources.
Otherwise you can downgrade to a 6.x stock firmware.
Option 1 and 3 needs you to unlock your bootloader. Backup important datas, unlocking bootloader wipe all datas!
Good luck...

I suggest you fully wipe your phone and install the May Google image (N2G47O). There was a major BT rework introduced with 7.1.2 that fixed an issue just as you describe. I went 5-6 months without being able to connect with one of my cars (2014 Cadillac). When the 7.1.2 beta came out I did a fresh install and it immediately fixed the problem. BT has worked flawlessly since.

You need a completely clean 7.1.2 install.
There is a setting somewhere (I don't know where) left over from previous OS version or app.
My phone was doing the exact same thing with my BMW, and only my BMW.
Clean install of 7.1.2 fixed the issue for me.

I wiped my 6P today hoping it would resolve my BT issues with my 2015 Toyota Highlander. No such luck, it still boots my Toyota in an endless loop until I disable the BT on the phone. The car works fine on my Samsung S3.

What is the process to do a Clean install of 7.1.2?

Bluetooth connection dropping with Nougat

I was having problems with Bluetooth dropping while on Marshmellow. After upgrading to Nougat my Bluetooth worked great for a few weeks. In the last week, I am having problems again with dropped Bluetooth connections. The problem is only with my Plantronics headset. I tried the headset with my wife's iPhone and it seemed fine. On my XT1575, after about 5 minutes of use the BT connection suddenly drops.
I have tried the following:
1 Forget and repair the headset
2. Clear cache on the BT apps
3. Booting phone into Safe mode and then pairing with headset
4. Clear cache on the whole phone​
None of these changes have solved the problem. I am thinking about going back to an old NANDROID or even trying a factory reset. Before I try either of those extreme changes, I want to ask this knowledgeable community for its advice.
EDIT, Also tried turing off BT scanning location and turning off Media Audio. Still getting disconnects!
thanks,

Have you done a Network Settings Reset?

Yes. I have tried Network Settings reset, at least twice.
Thanks for the suggestion. Any others?

I am going to try a NANDROID restore first.
If that doesnt work than I will do a Full factory reset back to Nougat stock!

You could reload the stock firmware too... it is available now, check the link in my signature.

Still trying to fix my problem where my Plantronics Savi 720 base station loses it connection with it's DECT headset. This only happens when my XT1575 phone is connected to the Savi base via Bluetooth. The headset and base stay connected when I use it with a landline or USB port. The BT connection seems to stay up, but the connection between the base and the headset is dropped. I ordered a new Savi 720 and still had the same problem (will be returning it soon). I tried my existing Savi with my wife's iPhone and did not see the problem.
Late last night I reflashed the whole -22 ROM which seemed to make the problem go away! After a NANDROID restore back to my previous 22 set-up, the problem came back!
After all the testing, the finger is pointing at some app or setting on my XT1575 causing the problem. Although, I still have the problem when I booted into Safe Mode.
I now tried just reflashing BTFM.bin. For my first test, the connection was solid for 15 minutes. It usually drops in less than 10 minutes. This is encouraging. Will report back upon further testing.
Any thoughts or ideas on what could mess up Bluetooth?

Was on a 30 minute call today with no drops from Bluetooth. Looks like reflashing BTFM.bin fixed the problem.

After 2 days of reliable behaviour, the BT connection problem has reappeared. I had two calls get dropped this morning. I reflashed the BTFM.bin file and still had the problem.
Im going to try to have Plantronics review the log file from their headset to see if that shows any information.
Can anyone suggest other options for testing or debugging?
PS: I am considering moving to another phone, like the Pixel XL 1st gen.

I'm assuming you have updated the firmware on the Savi as well and disabled wide-band audio? I had issues with my Plantronics Voyager Pro until I disabled wide-band audio.

Savi firmware is running the latest. Will have to check the setting for wide band audio when I get back home.
Thanks for the suggestion.

I turned off wide-band audio for deskphone and PC audio. I dont see a wide-band audio option for Bluetooth. Problem still persists.
I called Plantronics today. THe customer service rep has a Moto Phone, not a XT1575, and he has the same problem where the headset disconnects from the base. Even though the BT connection stays up. The rep claims that it is a problem the the BT chipset used in Moto phones. I sent him a log file from the Plantronics based. Hopefully, this issue can get escalated with Plantronics engineering.
I read the Nougat .23 has some updates to BT. I wish there was a way to try that. I am running .22. Isnt there anyway to downgrade back to MM so that I can than upgrade to .23? I know Acejavelin said it would brick the phone. Has anyone come up with an downgrade/upgrade workaround from .22 to .23?
Might be time for a Pixel XL 128GB upgrade (1st gen and not the 2).

The wifi issue was actually with my router so it's ok but thé bluetooth is a problem. I saw a Reddit post about it i'm not the only one with this issue. The bluetooth earphone only works when aptx is disabled.

Fastboot flashed the last PIE, then did the adb sideload of Q 5
Everything now works fine

Tested Bluetooth audio with q5 and it works with my pioneer head unit, my HD JBL headphones and my MC Helmet Bluetooth.

How's the battery compare to Pie? is it the same or better?
