[Q] Bluetooth pairing with Audi Phone system

HI, recently moved from iPhone4 to the Arc and love every bit of it...except the bluetooh pairing with my car's (Audi Q7 2G MMI) handsfree.
Pairing is intermittent and even when it's paired, the connection seems to drop off within seconds.
Does anyone else have the same problem especially with Audis?

Generally, they do that until the phone book transfers across - i know that's the case for the RNS-E. I have a RS4, did it all the time when I first got it with my Blackberry (had 2500 contacts). Just leave the car on accessory with the phone in the garage. I couldn't stand the dong noise everytime it connected disconnected.
Could be worse, I just got the AT&T branded Samsung Focus, it won't even connect with the bluetooth in my Audi or my wife's RR.

Thanks for the reply mate. When I did manage to pair them up, I could see all my contacts on the MMI's display previously. It's only recently that thsi connect/disconnect issue happened and it has certainly gotten worse today where I couldn't even hold a pair for more than 5 seconds.....

In that case - no idea.
Try deleting it on the phone and pairing again? Seems like a strange one.

Did that as well. Tried restarting, deleting and repairing - still no joy.
may have to flash my phone and try again as a last resort....sigh...

have you tried contacting Audi to see if there is a firmware update for the car?
There is a chance even of the car is brand new the software version the phone\ stereo system is using is a few years old.
Just a thought.

hey thanks for the reply. Yeah thought about that too and that's an avenue which i may explore with audi.
having said that, the condition has improved somewhat...it's still intermittent but at leeast it's now 'stickier'. What I did was I uninstalled the last 5 applications that I put in prior to the this happening and it worked.
No idea why.

Anyone else get these bluetooth issues? (hardware/software?)

My phone connected via bluetooth to my car no problems until yesterday. All of a sudden it stopped working, i noticed no other changes, so i proceeded to try to pair both from my phone end and the car, still wasnt working so i unpaired and removed the device from my car and phone and tried to repair, the car (2012 sonata) tells me to pair from the phone, and on the phone it cannot find the bluetooth of the car.
I was freaking out and thought it was the car, but i tried my tablet and laptop, andboth are able to pick them up, ive tried turning bluetooth on/off and restarting the entire phone,
Has anyone else experienced their bluetooth going out on the s5 yet?
and what do you think would help? factory reset, or manufacturers return for hardware error?

Have you tried pairing your phone with other devices than car? At least, it will confirm that your phone Bluetooth is working fine.

I've been experiencing some issues with my bluetooth in cars and with wireless headsets. it has annoyed me enough to search the forums today.
Issue with Pandora and bluetooth controls can pause, cannot resume play with MS530 wireless headset.
Issue with Pandora and bluetooth controls can pause, cannot resume play with 2012 Volvo S60 T6 R-Design.
Issue with Pandora and bluetooth controls can pause, cannot resume play with 2011 Volvo S60 T6.
Issue with Pandora and bluetooth controls can pause, cannot resume play with Aftermarket Sony deck in my truck (don't have the model handy).
Built in player sometimes has the same issues, I see more issues when the phone is locked. Fingerprint scanner on.
Today bluetooth locked up totally and had to reboot the device. I did not power down my headset before I left range of my phone and came back and it would not re-connect. I unpaired and attempted to repair and it would not. rebooted powered everything off and repaired and it started working again.
Bluetooth has issues on the S5 phones in my opinion. My iphone 5 has no issues at all with everything. locked or not. Was thinking of rooting to see if I could fix some of these issues as I prefer Android as I like the apps better and the openness to get stuff done.

No, it's not a S5 issue, it's an Android issue and it's been continuous since the beginning. These problems have happened with my previous 3 phones too, so don't delude yourself into thinking these are specific to this phone. Or that they will be fixed for that matter...

I disagree.
Bluetooth has worked on all the android models I've had in the past.
Past Android phones:
HTC Hero - worked great, slow though
HTC EVO - worked great
LG Nexus 4 - worked great
Motorola Zoom - worked great
Samsung Moment - Slow but worked
Samsung Epic - worked great
Samsung S3 - worked great
But if you want to blame the OS go for it. I think your alone there. Its a software issue with Samsung crap in my opinion vs security and all the bells and whistles they are trying to use. I think Android has nothing to do with the issue at all.

I have a moto headset with my s5 and no problems. Had no problems with same one on my s4 either so I wouldn't blame all the phones. It's electronics. Things can go won key when you have a lot of parts. It's probably just that. It happens. Even on iPhone's.

I have problems too. Very odd tho. I can pair my phone and listen to my music just fine. However if I try to use my gps while the BT is connected, no audio will cone from the phone or the BT radio. But as soon as I turn off thr BT on my phone, I can hear my gps through my phone just fine.
I haven't done a factory reset yet, but I have cleared thr phone from my car and re-paired.....still nothing.
The even stranger thing....every one in a while it will work, 9 times out of 10 it won't work. It has worked 2 times since I bought the phone, April 25th.
Never had a problem like this before, with other phones.

meh

As I reply to this one person said they have no problems, one said they have problems. I have had the same issues with syncing and playback on my 2 previous phones, neither of them the S5. There are idiosyncrasies that exist in the software (like any software ever) that just don't work sometimes. I don't know why we should think this phone would be any different.

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:

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.

Bluetooth blues

Hello all.
I am having some bluetooth connectivity problem with my moto g 4 US xt1625 Retus channel (non amazon version) stock everything.
Basically the connection to my smartwatch is unstable and keeps dropping on and off.
Normally I would be blaming the smartwatch for this BUT it connects absolutely perfectly to my moto G2 (cyanogenmod 14) without any hint of misbehavior
I've already tried;
Forgetting and re-pairing device (also rebooting phone before repairing)
Factory resetting watch
clearing app data and cache of system bluetooth apps ("bluetooth share" and "bluetooth MIDI")
Disabling 4G (sometimes interferes apparently)
Disabling wifi
Running phone in safe mode.
*edit - also tried disabling power optimisation for both system bluetooth apps AND the watch companion app
I also reconnected my smartwatch to my old moto G 2 after trying all these things and it still works perfectly.
Old moto G2 had blutooth 4.0 LE and this moto G4 has bluetooth 4.2 LE which would offer no comparability issues.
Has anyone had any similar problems with their bluetooth?
Thanks in advance

I think my next move will be to root, and start removing G apps that could be interfering with the bluetooth connection

I have had a problem with my Fitbit connecting that didn't happen on my G2 or G3. I keep my cordless home phone connected with no problem though. What I have to do is forget the Fitbit in my bluetooth devices and it connects fine. If it's even showing up in the bluetooth devices it won't connect. That seems strange that it will only connect that way but others have reported the same thing. Maybe try and see if it connects after you forget it in the bluetooth settings and it's not even showing up.

OK maybe you're on to something.
If I connect to the watch using the companion app, then enter bluetooth settings and "forget" the device..... It still appears to be connected
But a few seconds later, it automatically pairs and re-appears in the "paired devices" list.
Is there a way to prevent re-connect?

Actually, after "forgetting" it several times, It's staying connected and has done for a 15 minutes now.
I'll report back if and when it disconnects.
Cheers

Ok so the watch disconnected a couple of times in a few hours. (this is a huge improvement from before)
Each time, "forgetting" the watch in bluetooth settings caused an automatic re-pair and return to good connection.
Maybe I can use "tasker" or similar app to automate this unpair upon disconnect?
Cheers

Yeah, it's strange that it works that way. I think it's the device not compatible with that version Bluetooth. My Fitbit doesn't try to reconnect once I forget it unless I make it pair then it will actually work sometimes and sometimes it doesn't when paired. It always works if I don't pair it at all. Have you tried clicking on the gear besides your watch in more settings once it connects and unchecking what ever connectons it shows in the check boxes?

If i click the gear next to the watch in the bluetooth settings, the only options i have are to rename the device, or to forget it
I have no checkboxes or anything like thar.
Do you have advanced bluetooth settings installed or something???

Some of my devices have check boxes for contacts, audio, etc. but not all. I thought maybe that would be something to look at.

Ok, its still messing around. I'm going to install the Temasek unofficial cyanogenmod 13 and see if that is an immediate fix, or if the additional options offers a fix.
Cheers

update;
after ugrading moto g4 to android nougat (7.0.1) I no longer have any issues with bluetooth connectivity.
6.0.1 was to blame!

my phone is updated to stock Nougat also and still having bluetooth issues staying connected to my car (2012 ford fusion with mysync) I will be keeping an eye on this thread.

I seldom connect my phone to mysync but my wife does. She also keeps her G4 connected to the Panasonic home phone system while home. I've noticed that since the update to Nougat mysync is very slow to connect on her phone. The Panasonic cordless phone seems to connect fine. Mysync will usually connect although she has to drive for 10 or 15 minutes before it does occasionally and other times it connects instantly. One time I had to delete her phone in the car and add it back. I wondered if it was a problem of it not disconnecting from the Panasonic, but that shouldn't be past the end of the driveway. Then again it may be just a rip in the space time continum. ?

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.

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
