Question Bluetooth Pairing failed - Vivo X80 Pro

I'm currently trying to pair my SmartWatch and navigation device with the vivo. With the SmartWatch, Coros Vertix 2, it worked straight away.
With the Hammerhead karoo 2, however, the vivo is desperately trying to establish a connection.
Pairing works, the number code came up briefly at first, but it doesn't appear in the app, not even under the available devices in the BT settings.
Tried lots of tips, removing all paired devices and then restarting, activating/deactivating BT, restarting the navigation device etc..
Nix.
Anyone with an idea what the problem could be?

Solved the Problem with the Help of the customer Service of Hammerhead
Hard Reset of the Karoo and new Pairing wihthin Seconds.

[Q] Bluetooth connection problem

Hello Everyone,
I have a Note 3 Neo 7500Q ( Turkey Version). I am overall satisfied with the phone, but when I try to connect to my multimedia car kit via bluetooth, I have problems. It pairs up with the kit, but neither my nor the other parts voice is transmitted. I tried to every way without luck. Does anyon else has or had the same problem? Is there a way to overcome this issue? All kinds of help is appriciated.
I use the BT car kit all the time, with no issues whatsoever. My unit is a Parrot MK9200 or something. It is 4 years old, can't remember the exact model number. Phone calls, music streaming etc. works fine.
Here are a few suggestions you might try:
1) When I had the Parrot initially, 4/10 the phone was failing to connect over the Bluetooth. I upgraded the Firmware of the Parrot. Ever since, no connection issues. Check whether your Bluetooth unit has a FW update!
2) When the phone pairs with the car the first time, it asks for permisson to access the Phone book, logs etc. Mark "Always yes". That might be your problem.

LG G3 Bluetooth Pairing Issues -- not connecting to car

Ive been having problems connecting my LG G3 Official Tmobile ROM to my Hyundai Elantra. 9/10 times it doesn't detect the connection at all. It takes several attempts at unpairing the phone, and disconnecting the system on the car before it connects once. Here is what I have done so far without success.
- unpair device
- factory reset car system
- cache and clear bluetooth.apk
- use autoconnect bluetooth apps
Yet it never auto connects. Does anyone here have any solution to this? I used to have Huawei Ascend which used to connect perfectly to my car everytime.
Bump. Help anyone? Im on breadcrumbs now and even ready to install another rom if it helps with my issue. Can somebody let me know if that will do?

Bluetooth Connectivity Issues - Limitations?

So I have an Eonon GA1312 Single din (RK3188).
I have been having two bluetooth issues. All have been troubleshot by disabling and enabling/deleteing data/cache of Bluetooth app, different settings and "off" in factory settings for bluetooth tab and a reload of malasyk rom after a factory reset.
Bluetooth will always show every device it sees. I have 6 Devices under "available devices". 2 I know of (game pad and OBD). 4 were because things were in range when scanning. They persist through everything. It's so weird.
Secondly, the ODB, while off is "available", but once conmected it jumps to "paired" devices and connects no problem. My game pad (nes30 pro to test the viability of bluetooth media control without buying one) is there whether in range, on, or not, and if I try to connect, I tap it, I am asked if I want to connect, and it does nothing.
My cellphones connect fine.
I read all over about some bluetooth limitations but found nothing documented on tje wiki or in the forum.
Any help? Sorry if repost, I thought I made a thread but it says it isn't there and I have no move/deleted notices.
Bump for justice.

bluetooth pairing issues / delete paired devices

Hey guys,
since I bought my bluetooth headphones (Wearhaus Arc), which are actually pretty cool, I have lots of troubles with them.
When I paired my phone (HTC One M8 running latest official stock unbranded Android 6.0) with the headphones the first time, everything was great.
While using them from day to day I was faced with connection issues. That means, that both my phone and headphones are on, but it takes (almost everytime) a couple of tries to connect them. Even if I tap in the saved devices on the headphone, the connect could not be established. Turning off and on the headphones and bluetooth on my phone was the only way to fix it.
If I finally had a connection, everything was fine. In a few very rare cases, the connection worked at the first go.
Some weeks ago, a new firmware for the headphones was released, so I wanted to install them. During the update process, the updater (Android app) said, that the verifcation failed and the firmware cound no be updated. Same behaviour with the Windows 10 app. Even with another phone it did not work. Seems like, something is wrong with the headphones.
So I contacted the support again (first time they gave me the advice to use the Windows 10 app to update firmware) and told me, that I have to return it for repair. The gave me a return label etc. and I sent it back.
After waiting a few weeks I finally got it back. With zest I turned them on, but the joy was marred, because my phone did not recognize them.
Before sending them back, I unpaired the headphones in order to start over with the new ones. Maybe this was the mistake...
I did some pairing testing with other phones (HTC Sensation, BlackBerry Q10, HTC HD2), which found the headphones immediately and worked fine. So my guess is, that only my M8 has a problem with them.
Pairing, unpairing and "repairing" (pairing again) between my M8 and the other mentioned phones worked well, so there cannot be an general bluetooth issue.
After doing a factory reset on my M8 I'm a step futher, because now the phone sees the headphones (somethimes), but it isn't able to establish a connection. In case I see it, I tap on the available devices, the phone tries to connect, but a second later I get the message: "unable to pair. Make sure your devices are on and discoverable, and then try pairing again". Rebooting the phone does not work. I also cleared the data and cache of the bluetooth share app and performed a network reset like described here: http://forum.xda-developers.com/htc-one-m8/help/htc-one-m8-bluetooth-wont-android-6-0-t3340279
My question to guys is, what can I do, to get the headphones to work?
Is it possible, that on the phone is still a piece of information left about the former connection, which refuses any new connection?
Is there a file on the phone, which stores the bluetooth connections? if yes, maybe deleting or editing the file could help?
Thank you in advance!

Bluetooth always reconnecting in car

The problem is to connect Bluetooth on a Moto Z Play Android 7.1.1 patchlevel 2/2018 (current in reteu, was same result with Android 6.0.1 12/2016) with a Volvo XC40 car.
The first pairing with Bluetooth succeeds for a second. Then, nearly immediately, both displays (car and mobile) show reconnecting for about 10 seconds. It has a connect for a fraction of a second, and then is reconnecting and so on.
Trying flight mode and then only Bluetooth enabled on the mobile did not help. IIRC it showed some message about "My Volvo Carnull not bonded" (the name of the car for Bluetooth is "My Volvo Car" and some message with typo, something like "conecnting not successful". After that I rebooted, result was the state before with reconnecting.
Did try this several times. Also did try to reduce the amount of Bluetooth access types the car tries. There are 4 connected: phone, audio, internet, contacts. Did also not help.
Has anyone an idea how to get a successful connection or what the cause of the problem is? Did search for similar problems with Bluetooth in cars, but could not find anything (except for that hint with flight mode which did not help).
What I tried by now:
- Flight mode, only Bluetooth (as already mentioned). No change
- Remove all bluetooth connections. Pair new. No change
- Delete data for sytem app "Bluetooth Freigabe". No change
All other bluetooth connections are working fine. Another Moto Z Play using Android 7.0 (01/2017) is working flawlessly with that car. Strange for me is that it didn't work on 6.0.1 in the same way it does now fail on 7.1.1, but the other Moto Z Play using 7.0 is connecting stable.
Still the question: Does anyone have an idea how to get the connection working?
Factory reset?
I see that you deleted all bt connection but do you have some apps that are using bt? Like for smartwatch, headphones...?
I have Amazfit and watch must be connected to be able to pair a new device. Drow me crazy first time when I had that problem. I thought that car audio is broken, then phone... After pairing, watch doesn't have to be connected to reconnect.

I was afraid this reply could come. When doing a factory reset, I do following: Pack /data/media somewhere because Nandroid omits this. Backup all partitions using twrp. Backup all apk using adb. Export SMS. Export contacts. Screenshots of the launcher screens. All this takes about 2-3 hours. Then I struggle a week until my device behaves like before. I'd be willing to do it if I saw a reason why it could help.

Headphone, yes, there is August EP650 configuration tool that is not necessary. Thank you for the hint, will try it. Also I read somewhere it may help to delete cache partition, that's also worth a try before doing factory reset. Maybe I'll wait for Oreo before trying factory reset, could be they fixed some bug there.
Edit: BatOn which shows Bluetooth battery for external devices could also be the culprit.

That's a strange behavior indeed. Amazfit seems to do something wrong.
It doesn't get any better if you upgrade to Oreo, I've been having problems with my Moto Z play disconnecting and reconnecting to the radio in my Corolla constantly ever since I went up to nougat. To be honest I just bought a good pair of headphones and stopped using the radio. Good luck though, if someone finds something that helps let me know.
I'm using bt with car audio, headphones, smartwatch... No problems at all, except one with Amazfit. And that is related to their bt implementation, not Moto fault.

Seems the last action to remove Bluetooth related apps was the right one . There were two apps installed:
1. BatOn showing the state of battery of connected Bluetooth device
2. August configuration app for August EP650 headset
Removed both as they are usually not needed and it seems to work now. Will see later if it only worked for the short test I did today (currently I try to avoid driving because of an injury) or if it keeps stable.
Good, you didn't have to factory reset after all
