Bluetooth always reconnecting in car - Moto Z Play Questions & Answers

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

Bluetooth not alive when phone is locked?

All,
I have this small issue with my HTC Desire and the Parrot CK3000 Evolution. Until now, everything works perfectly (calling, sending contacts, voice dialing, ending calls,...)
However I have one small issue. When I enter my car, and my phone is locked, the Desire will not pair with the Parrot. From the moment I activate the screen, pairing is done within a few seconds. I already tried to leave it there for half an hour, no pairing, touched the screen, pairing within a few seconds.
It looks to me like the bluetooth is not active / alive when the phone is locked (or in sleep). From the moment the pairing is done, everything works fine, also when the phone is back in lock / sleep.
Anybody has anything similar or has a solution for this? I searched the market for some kind of Bluetooth-keep-alive application, but could not really find it...
Thanks in advance,
Best regards,
Speedygerre
Small bump, nobody any idea for a solution or somekind of workaround / app?

I have a similar situation with my Audi A5 (factory BT kit).
It will connect when the phone is locked (screen off etc) but it can take anything from 1 to 10 minutes before it does connect.
Like yourself, my Desire connects immediately if the phone is not locked.
Strangely, it appears to work OK in my Mazda MX-5 which has a Kenwood DNX8220BT system (Bluetooth, SatNav, Ipod, coffee maker etc) - and the Bluetooth is a Parrot system. Having said that, I haven't used the MX-5 much since I got my Desire so it might not be a representative sample.
There is definitely something amiss though.
I have a Parrot CK 3100, and whilst I am happy to report that I do not have the same problem as you, I did have a problem syncing my contacts.
Check out this site, and download the software to udate to the latest firmware. You will need a laptop with either built in bluetooth, or a seperate bluetooth dongle.
http://www.parrot.com/uk/support/onlinehelpguides
I updated the firmware on mine, and now my contacts sync properly.
There is a good chance that updating could fix your connection problem as well.
Sorry forgot to add, that updating the kit really is a doddle, but their software is Windows 32bit ONLY and definitely no MAC!
Thans pergolesi, I hope your suggestion workshop, I will try it when I have some time one of the next days.
However I still think it has something to do with the Desire, since syncing workshop perfectly when Desire is not locked...

I don't know about the Bluetooth but I know my wifi deactivates after about 5 minutes when it's locked even though I have it set to never turn off. Maybe the Bluetooth is doing the same.
Perhaps not much help, but I sometimes play music from my Desire on my car headunit using Bluetooth streaming, and that continues to work fine when the screen goes off and the phone is locked. It also still responds to commands from the headunit (skip, pause, etc).
Once it's connected, everything works OK for me as well, it just is the connecting moment which apparently does not always work

Can I ask what year your A5 is? I've got a 2010 A3 and BT doesn't work properly with my Desire I can get it to pair, but then it will disconnect a few minutes later and the only way to reconnect seems to be to unpair/repair or switch the car off/on. When it IS working it can make calls, etc. fine - but I just can't get it to stay connected I tried my Audi dealer but they just said it's not on the Audi list and there's no update to support it, so interested to hear you got it working on your A5.

My A5 is a 2008 model with SatNav and therefore MMI High. The Desire paired straight away with no problems and both the car and the phone remember each other - it just takes awhile sometimes for one or the other to realise it and connect.
I'm pretty certain that it is the phone that has the problem as I had no such problems with several Sony Ericsson phones previously.

Thanks - interesting. I wonder how many different BT stacks Audi run - I was hoping they'd share some common code and therefore be updated quickly but it sounds like this isn't the case given that it's working fine on your A5. Thanks for the info though!

[Q] Bluetooth Upgared / Fix

can anyone tell me if I can update the Bluetooth in my HTC Desire or have more profiles. the phone is branded o2 but can be rooted. I dont want to change anything else in the ROM just make the bluetooth connect automaticaly & reliably to the car.
There are newer software builds available but have no mention of updating bluetooth.
Ther are no OTA updates available.
Software Number is 2.14.207.1
Andriod 2.2
Thanks for any advice in advance.
Trampsdad
Can't you just pair the 2 devices together? I personally don't use Bluetooth so no idea on that aspect. Also, the software is so out of date because o2 cba to release and update. There are major updates since yours. It might be worth considering to root so then you can flash a newer ROM, or infact, you don't need to root and just use an RUU. With the newest software. No need to root it then and less chance of it mess up.
Hope this helps
I still have some strangeness with Bluetooth. From what I read there are some updates in Honeycomb and maybe gingerbread. But I don't have a feeling what you are looking for is in FroYo
Sent from my HTC Desire using XDA App
Well I have a Kenwood Headunit with Bluetooth and the connection to that using stock Froyo and LeeDroid showed some interesting results. Gaps in the phonebook for instance. However, putting a 2.3 ROM (Ginger Villain) sorted that out, its fine now.
Bluetooth depends on the other device too.
What exactly is the problem you are having?
What Car do you have?
What Bluetooth system is installed (is it standard)?
I have used my desire in a number of cars (Vauxhall, Ford, BMW) without any isses with pairing, using the Phonebook,etc. is a different matter.
Personally, I have just received a new BMW 528i, and it doesn't get on well with my Desire at all.
It pairs OK and can use both the phone and music, but when I leave and return to the car, it just refuses to auto-connect again, and I have to go through the pairing procedure again.
Oh, except one - the time I went back to the garage to 'complain' about it and ask for advice, when it worked perfectly. Until I got home again!
Have experimented with my old Nokia N85, and that works fine, too. So it's either the Desire or an incompatibility between it and the car.
Oh, my Desire is running MCR r9 (FroYo) at the moment. Are there known issues with this? Info on any Bluetooth updates I could apply would be gratefully received!
i have to enter my pairing code every time i connect my bt headset - i took this to be a quirk for the moment - hoping its fixed in 2.2.2/2.3.x etc.

Im having this same problem also with a Pioneer Head Unit in my car.
Bluetooth has always been troublesome as it doesn't auto connect. It will connect if I either manually click on "Pioneer Head Unit" or turn Bluetooth off and on (which I automate with tasker).
The pin thing is new and happens with all roms I have tried except LeeDroid, (which I prefer not to use as I don't like sense much). Leedroid still has the auto connect problem.

Some good hints there - thanks!
I can connect far more reliably if I initiate the connection from the phone than from the car.
Likewise, if BT is switched off on the phone and then turned on after the car is on, then it sometimes works, too. Certainly don't need to re-pair anywhere near as often.
Can I ask how you use Tasker to automate the BT switching? I've not used that (I use Setting Profiles instead which I understand does roughly the same thing), so am curious what kind of rule you have that's useful for this.
Cheers.

I use the following rules:
On wifi connection turn off bluetooth
On wifi disconnection wait 30 seconds and turn bluetooth on.
If not wifi connected & not bluetooth connected turn bluetooth off and on every 5 minutes.
If not wifi connected & not bluetooth connected and incoming call turn bluetooth off and on.
If not wifi connected & not bluetooth connected when display switched on turn bluetooth off and on.
The battery drain hasn't been a problem, if I go away or won't be using my car for a while I disable tasker. Of course this doesn't help when it keeps asking for the pin.

Ah, cunning! Of course...toggle it when it's not already connected. Prifile Settings doesn't seem to let me toggle things like BT directly, although I could probably do so by setting some appropriate profiles.
I'll have to experiment...or just buy Tasker, instead!

True, but so far in my case, I've only had that when I've tried to initiate connection from the car. Hopefully your trick will mean I don't need to do that so often.
Anyone found a gingerbread rom (or any rom!) with improved Bluetooth?
I have found the bluetooth to be terrible on the desire. I have got about 3 devices that my phone just refuses to pair with.
Currently I am trying to get it to connect with an Elm 327 Obd scanner. No luck, it asks for a pin, then I enter the pin, but it immediately rejects it.
I have tried oxygen rom, leedroid, stock froyo, everything...
I also have a parrot hands free kit that does the same thing, asks for pin, then does nothing...
Something makes me think it might be the radio or something. Except that my phone DOES connect with my scala motorbike helmet... So frustrating

[Q] Bluetooth Borked

Hoping someone can help shed some light. Googling didn't turn up anything. My S6 after the 5.1.1 update, bluetooth is borked. It is connected to my Sony Smartwatch 3, Gear 2 Neo, and was connected to my Fibit Charge HR and Microsoft band. The Fitbit Charge HR got a firmware update and then would not pair with my S6, but would pair with my work iPhone. So I thought it was defective. But it pairs with my old S5. So I went into bluetooth settings and did a scan and it will not see it. So, I stupidly unpaired my microsoft band and now it's now recognized at all. The SW3, G2 Neo are paired, as well as my Sync in my car, but show up in bluetooth as "Not Connected" even though they are. This is frustrating and I don't want to go back to my S5. Everything else seems to work okay - just the bluetooth. Anybody have any thoughts? I'm on the latest OTA, OFE.
SO no one's got any ideas. I have wiped cache both while normally running and by booting into recovery. Bluetooth still hosed. Would a factory reset help?

I don't think it does. See screenshot. All of these devices are paired and connected, but bluetooth says they are "Not Connected".

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!

Question MIUI 14 Bluetooth problem

Hi folks.
Does anyone have problems with bluetooth after the MIUI 14 update? The headphones lose connection even when turning the head slightly and the smartwatch is always disconnected. I tried the devices on another device and they work as they should.
I have already factory reset the device and reset the network settings.
Thanks in advance.
Firmvare: MIUI Global 14.0.1.0 (TLDEUXM)
I'm facing same issue, no solution though
I have also the same disconnections Bluetooth error
Don't have any issues on same firmware. Try to reset your connections settings. Wi-Fi passwords will be lost in this case.

I already done, i also remkved the wipe data for the Bluetooth, i redownload the firmware and j install but nothing seems to working
After the last update my phone wont connect to car via BT. Older phones works great. Connecting settings restart and clearing BT cache did not help.
Mine connects to the car Bluetooth and music works well, but on phonecalls. I get disconnected or people say they don't hear me properly.
There is definitely an issue.
I found a solution on a german speaking forum: goingelectric.de
TaskerNet

Guys check if you have bluetooth update. When I went to bluetooth settings today I got a popup about bluetooth update.
