Bluetooth problems (DK28)

I've been having issues pairing/connecting to one of my bluetooth devices. I currently have 2 devices paired with my phone and they work flawlessly. The third device worked fine for about a month before it stopped connecting. It was still listed as a paired device, however it would not auto-connect nor manual connect (it would flash connecting for a second, but that was it).
My next step was to unpair and try and start from the beginning. If I unpair and try to pair again, it will say "pairing..." indefinitely. Afterwords, I will toggle bluetooth and the device appears again as a paired device, but I am still not able to connect. I've also tried unpairing and toggling bluetooth, but as soon as it comes back on the device is still listed as paired. I've also tried rebooting the device, but the results are the same.
For the record, I was able to pair and use the trouble device with an Evo without issue. I was also able to unpair from one of my working devices, and pair again with no problems. I'm really at a loss as far as what to do short of formatting the device. Does anyone have any other ideas I could try?
Thanks

I sometimes get the same problems but there's nothing we can do about it. DK28 is a beta build that's bound to have problems.

I get the same problems occasionally. DK28 is known to have several issues with Bluetooth.

Is there any way for you to do a hard reset on any of the bluetooth devices?
I know I had to do this with my Jawbone Prime for my Epic.

I also have a big issues with the bluetooth pairings.
Can't pair any device, actually
But I have a backup data with all my pairing bluetooth devices. I've made that backup from 2.1 Eclair. I can restore it, but it is old backup. So, when I've tried to backup all of my bluetooth pairings with the Titanium Backup I can't restore it with the new data. That is very interesting because I can see all of my bluetooth pairings backups after I'm restoring the new data but there is no restore button. I can see those backups but I can't restore it.
Can somebody give me the Idea what to do and how can I make bluetooth pairings?
Help me, please?
Thank you!

I had some bluetooth problems as well when on some of the current EXT4 ROMs.. i have reverted back to RFS and an older ROM build and things work better.

Guys, I would seriously try looking up a way to do a hard reset on your bluetooth devices. I had to do this with my Jawbone Prime earpiece with my Epic running Quantum 2.7.0. I have it converted to ext4 via cwm3 and it works fine. I would suggest giving it a shot. The worst that can happen is you still have an unpaired bluetooth device.
For my Jawbone Prime I had to do a specific pattern of hitting the talk and Noise Assassin buttons. It paired up immeditately with my phone. You may have to do similar with yours, depending on what you have.

I installed a brand new Parrot MKi9200 in a van for one of my customers. This parrot piece would pair with my phone but not connect. This was running an EXT4 version of Bonsai. I grabbed my boss' Fascinate (stock 2.1) and it paired up just fine. I went back to an RFS only version on my phone and it paired perfectly.
Also as was previously mentioned, resetting your bluetooth device after a ROM flash can help with connectivity issues.

I think I found a fix for the pairing issues on DK28+
I had to turn off bluetooth, the adb shell, su, go into /data/misc/bluetoothd/ then I renamed/added _ to the file there. "mv xx:xx:xx:xx:xx to xx:xx:xx:xx:xx_" (which should be the MAC address of the phones bluetooth radio)..
Then turned back on bluetooth.. And that fixed pairing. Good luck.

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 have the same issue pairing to my car's Bluetooth keep pairing failed

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.
http://forum.xda-developers.com/nexus-5x/help/issue-android-nougat-bluetooth-issue-t3446073

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?

Anyone else having bluetooth connection problems?

I've had my Z Force for about a week and a half. At first, everything was fine, but now, BT won't automatically connect to all of the trusted devices. It automatically connects to my BT speaker at work, but not the one at home or my Ford Sync.
I'd appreciate any thoughts.

Having an issue with it dropping the connection when paired with the LG Tone Platinum HBS-1100.

I have mine since Tues. Connected to 2014 Honda and Moto 360 and Moto sd 11 headphones. No issues I have noticed, especially in the car. It connects quicker and continues pandora quicker than any phone I have used previously with the car (LG G2, LG G3, Turbo 2). I will soon test with a Ford Sync 3 system, a vizio soundbar, and an ECOXGEAR speaker, and some ihome cheap headphones. Hopefully all goes well.

09 Ford with sync. Having issues as well. Don't have trusted devices set up because of the fingerprint reader, but I do have issues with automatically connecting, especially if I leave the source on Bluetooth audio when I turn the truck off. If I hit the phone button, it will usually reconnect. Don't have any issue with my moto 360 though.

I think it's a Ford sync problem. I have a 2015 fusion. Mine connects but it's delayed. Unfortunately the automotive radios are only designed for specific bt protocols. This is a problem with many car systems. My wife has the same problem with Dodge uconnect and the g5.

But mine worked fine for the first week or 2. It also is a problem with my BT speaker.

Bluetooth Connection
The same thing was happening in my Subaru, so I went into the voice settings of the moto actions app. Once there, choose "Talk to Me" and then touch more options. Once I selected the "audio troubleshooting" button, my car bluetooth problems went away instantly. Maybe something to try if you haven't?

Yeah Ford doesn't have any options like that.

So, the simple fix was to go empty the Bluetooth Share cache. Seems like a simple idea, but I had never needed to do this on any other phone.

I'd had mine a while and one day I noticed my BT wouldn't connect to my speaker at work. So I tested it on all my devices and my Bluetooth doesn't work at all. It will not find any device at all. Yes I've made sure they're all on sync, search, find, whatever the option is. I've cleared cache, tried to dig deeper to find that there are no legitimate settings or options menus, no way to troubleshoot the issue. I even thought an update would fix it as I thought it had updated just before I noticed it not working. Well it's updated again and nope. Still no Bluetooth. I've given up. And to beat all, no damn headphone jack so I gotta remember to carry around my adapter to use an aux cord.

On Bluetooth people can hear me but I cannot hear them.
I have had my Moto Z force for a while now, and all of the sudden when I connect to any Bluetooth device I cannot hear anything when it comes to phone calls. All media works, and people can hear me. I have factory reset the phone to see if this fixes it... But it did not work. Anyone else have an idea or experience this issue?

Hi, I have the same problem, suddenly after upgrading to nougat, I can not detect the wi fi and bluetooth.
Let me lower your stock:
XT1650_GRIFFIN_VERIZON_7.0_NCLS25.86-11-4_cid2_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml
But I do not know how to flash

I have the same problem too 3 days ago. It stopped working randomly. I was running Nougat with December security patch. Tried hard resetting and nothing. Now I updated to the January security patch and I still have the same problem, even after doing another hard reset. Could this be a kernel glitch or a driver issue? Bluetooth says it's on but it won't find any device and I can't pair any device to it. I hope Motorola is looking to fix this because I am from Europe and can't send the device to warranty in the US .

You can send it out, you just need a forwarding US address... You can do this if you do it with a middle-man https://www.shipito.com/ for example. might cost a little more for shipping, but it's an option that you have at least!

Thank you so much! I'll send it to warranty in the end. Moto is going to completely replace it. I'll have a Z Play to play around with meanwhile and then I'll see wich one of the 2 I'll keep.

My Moto Z has a similar issue. I got my first unit last summer and had to return/replace it because the charger melted to the phone (but that's another story). With my new phone, I constantly have trouble connecting to BT. I can almost always connect eventually, but it's NEVER on the first try. I usually have to toggle BT off and on, force stop BT, or restart my phone. So my Bluetooth isn't quite 100% useless, but it's a huge inconvenience any time I need to connect to anything.
Also fyi this is not related to the Ford issue--I'm connecting to headphones and speakers.

Bluetooth on G5
I can't connect to the handsfree on Mitsubishi Mirage

I'm having the same issue. All Bluetooth devices just quit. Headphones, Watch, Car adapter. Everything. I've reset my phone and nothing. Anyone had any success with any fix?
[Update] I think there may be something up because I mentioned it to the customer rep and they immediately said I need to send it in.

Same issue for me.

My Bluetooth is very problematic too. Whenever I connect to car device it just auto-disconnects. FIX THIS PLEASE LENOVO!!!

Bluetooth issues

I have 3 main devices that I pair to my phone via bluetooth: watch/lg tone/car
The watch stays paired with no issues, but the watch is having issues swapping from the lg tones to the car and vice versa.
Anyone found a remedy for this?
As of now, I have to go into the bluetooth settings of the one I don't want to use and deselect media/phone, then go to the other and select media/phone. And even sometimes this takes multiple times to work.
My previous phone (gs7) had no issues swapping from the two.

Hi,
Did you get a solution ? I face the same problem and can't find any solution...

Just to clarify, when you are in your car and want to connect to it, the headphones are turned off, correct?

Having similar issues... Every time I try to connect to my car (stock Subaru WRX), I have to manually connect and it takes several attempts before it connects. Once it connects it usually doesn't drop though. Very frustrating...

It's not in my car but with the bluetooth device of my motorcycle helmet. The reference is ncom bluetooth kit 3. I have to connect it manually and it takes several attempts before it connects. Sometimes it doesn't connect at all....

I have 2 headset Plantronics Backbeat Pro and Plantronics Backbeat Fit. They both work flawlessly
My Huawei Watch also works.
But my Nokia 616 Car kit wont connect at all.
And my motorcycle hemlet bluetooth kit, Cardo scala rider PACKTALK, connects, but the audio is slowed down to about 80 percent?

Same thing here.
I have been facing problems with a Sony SBH52 Headset and with my Opel Corsa E, stock infotainment system.
It gives me a hard time connecting but when it does it's stable.
I had the same with my gen 1 Moto 360 but after a factory reset to the watch and a reboot it's stable.

I had the same issue with my TSX. I did some research and cleared the cache. Worked like a charm afterwards. Did not have the issue one week since doing that

Ahem, I seem to be unable to find bluetooth in my app settings. Can you please give me a hint?
It's been driving me crazy these days with my SBH-52 and I want to try this too.
Thanks!
P.S.
I'll also give it a shot with a plantronics pro headset I have to see if it does the same.

Bluetooth profiles implementations, even though they passed certification, are not always made equal! So don't end up pulling your hair if a certain BT device doesn't play nice with another.
Just as an example... Head Unit X had big issues with the initial contacts sync, right after pairing with Samsung phones (already known to sometimes play around some other standards). It would only work after several reconnects. After several weeks of debugging (poor development guys) and reproduction test (poor testing guys) it was concluded that it is a phone issue caused by some wrong timing delays in the process of exchanging information between the HU and the phone. Samsung was informed and the ticket was internally closed.

I have similar problem with Bluetooth Earbuds. Phone simple doesn't "see" the Earbuds. But strange - it can see other Bluetooth devices and other devices can see Earbuds.
I'm sure this is a OnePlus 5 software problem.
Version OxygenOS 4.5.10

i have somhow issue as urs, i have Bluetooth pad lock and android watch, it sometimes connected and sometimes not, i do believe its software issue, im on 4.5.11

Yes, it is strange. After some restarts and on/offs connection suddenly appears

LG G6 with Bluetooth Issues

Problem: Intermittent Bluetooth connection with my Prius C. Found two Bluetooth apps in system apps.
When I go into the bluetooth app to clear cache and data, I noticed TWO Bluetooth apps! One is version 8.0 which is appropriate since I've upgraded to Oreo. And, the second Bluetooth app is version 6.20.18. After trying everything I could think of to fix my connectivity issue, I'm at the point of a factory reset and rebuilding my device with hopes of resolution. But first, I wanted to ask if anyone else is seeing TWO bluetooth apps on their phones? Settings/Apps & Notifications/ Apps, then expand menu to show system apps.
Again, is anybody else seeing two bluetooth apps? Wouldn't this create a conflict with anything trying to connect? How can I delete the old app since they are both system apps? TIA

I've also got two apps. Enable Developer options and try to change Bluetooth - AVRCP version to AVRCP 1.4 (Default). After that my TomTom watch could connect to G6 without problems. Maybe it will be also a solution for your problem.

Thanks for the suggestion. I've done as suggested with mixed results. I unpaired my G6 from my Prius, deleted the G6 profile from the Prius and still got the BT connecting and then disconnecting. I didn't have time to reboot so I wonder if that may be my issue (cache memory?). I'll try that at lunch. However, after a minute or so, I was able to stream uninterrupted. Thanks for the suggestion and solution, hopefully

I'm having a similar issue with my G6 and a 2016 Subaru Outback. Keeps dropping the connection and connecting. Sometimes it is ok for a while. Sometimes it keeps doing it from the time I start the car. Worked great until 8.0 update. See thread here: https://www.subaruoutback.org/forums/138-gen-5-2015-2019/501767-bluetooth-connection-issues-lg-g6.html#post5728313

Update: Still having mixed results (when connecting to my Prius). so, after some connection back and forth, I have been successful with streaming Pandora and Amazon Prime for more than 20 minutes w/o interruption.
I've tried Google Play in the car and it's as if the connection is possessed. It's so unstable that it makes me believe Google Play is somehow responsible. Yet, my BT headphones connect and play without issue for over 1hr while mulching leaves.
I still don't fully understand how their can be 2 Bluetooth apps on my phone without any type of conflict, especially since they are different versions. I'm thinking that when my phone updated to Oreo, the old Bluetooth app/file didn't get removed.
@TheGs - Have you done a factory reset? If so, how many bluethooth files/versions on phone after reset? I was hoping a reset would fix this puppy. I too am on TMo/H872.

I still have two apps after a factory reset. (I'm just here because I've had bluetooth crashing after the latest OTA from T-mobile.)

UPDATE: having followed the suggestion from @adamz667 above, I changed the AVRCP to 1.3 and so far so good. Bluetooth just connects with no interruptions what so ever. Maybe this will help if you are having simiilar issue.
@lovecomplex - thanks for replying on the number of bluetooth apps you have after reset. Now that I seemingly have resolved my issue I see no need to reset at this point, Good Luck!

got a brand new G6. Bluetooth is broken out of the box. I can't stream anything to any bluetooth devices. Changing it to AVRCP 1.3 under Developer Options made streaming possible but it is choppy. I am on Nov 1 android security patch.
WTF LG? It is brand new, brand new!
