[Q] Bluetooth car connection

Problem : car :
Peugeot 407 (2008)
device : Nexus One (Rodrig. latest)
I always had troubles getting my device paired with my car, but mostly after a while or installing "bluetooth file transfer" it worked.
However not anymore. Does anybody has an idea what the problem could be? Are more people experiencing this. The devices see each other but they can't connect/pair to each other.
I also tried the app. "bluetooth fix" but it gives an error. Even after reinstalling the "Super User" app from the market.

(sorry I wanted to replace it to Q & A)

linking and transfer of phonebook is good, but quality is very bad. It is difficult to hear the other side, most of the time I have to take it from handfree and talk into the phone directly...
using cm 6.1 rc1

Had that too. Use a kernel without audio-mod.

It works but not really at the same time ..
I can receive calls but I didn't manage to get my phonebook on the car or make a call from the car, I have to dial through the phone.. Not sure actually if its possible or not with my car anyway...
Phone: Nexus One - CM6 nightly 263, with radio 5.12 and Wildmonks 112210 kernel
Car: VW GTI 2010 - RNS510

Does anyone also have a problem with using his bluetooth?
My phone sees my car's bluetooth but can't connect.
It always gets rejected!
It used to work on early Rom releases.
I am searching the net and this forum but I don't see any solutions.
There is an app on the market to fix bluetooth but it didn't work

Problem car: 2010 Audi S4
Phone: Nexus One (ATT) 2.2.2 (unrooted) Radio 5.08
Phone pairs. Cannot answer calls through the car controls. Must answer physically on phone in order to answer call. If picked up by car controls, the car says connected but no audio.
The system used to work perfectly before while on eclair 2.1. I think Froyo screwed something up for me.

I'm also on CM with audoio issues. which kernel did you use, and is it affecting other areas of your phone pos/neg? i.e. do you recommend the switch?

The latest from wildmonks without Audio Boosts are :
http://wildmonks.whoisthedrizzle.com/kernel/2.6.35/010411/No_Audio_Boost_CM6/
These are good.
However I can't even connect anymore (had the no audio boost too when in the time it could connect)

I also have an A4 with nexus one on CM 6.1 (still with audio boost) and it works perfectly (except for the sound quality). So might be a specific issue on your phone side, or maybe the new audi SW (mine is from 2008). have you looked at this thread?

My Bluetooth connection is REALLY BAD

I have searched the Desire hd section for any Bluetooth problems, but seems that im the only one with a problem????!!!
My Bluetooth conectivty SUCKS with any headsets!
i have tried 4 diffrent headsets! and all "god" ones.
But i get the same result, as soon as i move i get lots of bad sound (Donw know how to explane, but like a Tv sound without a signal)
and i have to have the phone at a maximum of 5-10 cm so i can get a "good" listning sound.
The person who talkes with me have no problems.
I tested with 3 diffrent Nokia BT
one of them is bh-606
Jabra Bt as well.
I have the latest firmware. But lots of apps in my phone? can that cause a problem?

Try settings/energy saving function/ deactivate bluetooth. (Turn off)

Hmm Thanks but that only says that it will close Bt connection while there are no calls active?!
I can alsaw add that my Wifi Connection sucks aswell. tried it with 3 routers. and if im not in the same room so the connection is not even detected! But if im in the same room i came upp to 18 mb download with a speed test app. So the Range seems to be a problem both for the BT and Wifi.

Update your radio. Find how to by reaching.

Have even tested more on the BT part and discovered that whenever im nearby any Electrical eqwipment like Pc or Tv it gets even worst!
At best its when i have it in 10 cm distance and with no electrical things around! and not moving at all. then its Near Okej.

Need to use BT units while driving + at work and i cant!
Edit:
i did a little test today with a Stereo Bt unit!
then bt connection works well!
so it seems that the problem is a software issue and its only with mono bt units!!!

Yet a nother sieries of tests!
I have now concloded that its the Mono Bt units i have problems with, and that its a software issue!
I used the BT in my car, and the sound works without any problems..
And i tested with a Nokia Stereo Bt, and same there, even upp to 10 m i have a clear sound..
SO it seems to be only with regular mono Bt units i have this problem!
Any tips?

[Q] Bluetooth on Nexus 4 woes

Trying to connect the N4 to a car Bluetooth audio (2012 model car, relatively new, only 9 months old).
(1) I had a very hard time getting the two paired: lots of "connection failed" attempts until they finally connected.
(2) The phone does not send artist/track info which is surprising as I have an older LG phone running Android 2.3.4 and that sends all the info.
(3) Without any music being streamed to the car audio, if I make a phone call via the car bluetooth, when the call ends the music player on the N4 starts automatically. This is very annoying, not sure if it's a problem with the car implementation sending a "play" command at the end of the call or the N4 doing something weird. I tend to blame the N4 as two other phones, an iPhone and the older LG mentioned above do not do this.
(4) The car has a play/pause toggle that it can send to the bluetooth player. Pause works, the player on the N4 pauses, but then play doesn't work, I have to hit play on the device.
(5) After I use bluetooth on the N4, I find that sometimes the widget toggle can no longer turn bluetooth on/off until I reboot the phone.
(6) After I use bluetooth on the N4, the phone sometimes randomly reboots. Not sure if it's really related or just a coincidence. Given (5) above I suspect something is going on.
Anyone else having such a hard time with the bluetooth part? Potential hardware issue or simply buggy software that we can hope to get addressed at some point?

I have experienced the issue with track information not being sent. Also random changes in volume during playback. Seems there's still some work that needs to be done in 4.2 regarding blue tooth.

Is this an issue that can be addressed by flashing a custom ROM or perhaps using a different music player than stock or is there more to it, deep down in the bluetooth drivers and it would need a fix from Google in the form of new drivers?

Yeah I have had a few issues too. My track/artist/album names do not send where my S2 sends them. Also the headunit I have has buttons for shuffle and repeat and these do not show up at all (I assume because it detects they aren't supported). I haven't taken a call yet or tried turning BT off after streaming but I'll give it a shot and see.. My nexus 4 also randomly shuts down for no apparent reason sometimes (rarely atm). I think it's just 4.2.1 problems - I doubt a different music app will fix it (I tried one), custom ROM may work though..

My N4 is paired with an Alpine 135BT and it's worked very well so far. I initially had some trouble connecting but once they were paired I didn't have any additional connection issues. The N4 does automatically play as soon as it connects to the unit. I've got BeyondPod and Spotify installed and for whatever reason it always defaults to BeyondPod instead of Spotify even if I had BeyondPod closed and Spotify open. Not a big deal to me though.
Are you running the stock rom or a custom rom? I had my EVO LTE hooked up to the same head unit. It worked perfectly on the stock software but gave me all kinds of trouble when I started using custom roms. Otherwise, it could just be that the N4 and your particular head unit just don't play nicely together.

(1) Haven't had any connection issues so far on my vehicle or my wife's.
(2) Currently stock Android uses AVCR v1.0 which only only allows you to control via Bluetooth (play, pause, etc) but not send track info. Other manufactures that customize Android (LG, Samsung, etc) will sometimes use v1.3 that supports track info. That's why your old phone did it.
You could install a custom Rom that has v1.3. I think cm10 does.
(3) Again, not happening on my two cars. The only time the music starts after a call is if it was playing before the call. I'm wondering if you have another music/podcast player that is taking over Bluetooth controls and causing problems. I use the stock player and Player Pro. If I don't disable the headset/BT controls in Player Pro I have control issues.
(4) I have the same issue. To get around this I cheat and push the track advance button on the radio to play the next track.
(5) This is an issue I've had on all of my previous android phones. I haven't noticed I my N4 because I never toggle off Bluetooth anymore.
(6) Not having this problem but maybe try solution in (3).

got the sony mw600 for bluetooth audio.. no id tags on display.. on every musicplayer (play music, poweramp, cm musicplayer..) the same.
dont know why, but today even the start/stop, forward and prev. buttons didnt work! the only thing i can use is volume control..
anyone an idea?

Any luck with this?
I want to buy one but couldn't find it in Sri Lanka so planning to order one via ebay & need to check if it works. Running cyanogen mod 10, heard that the bluetooth stack was updated on CM which supports most of the features since stock rom only has older stack version which can have issues!

I also have the track name issue. This is a massive let down. I like to just get in my car and flip through tracks with my phone in my pocket. My iPhone did this, my s3 did this. Why not the nexus 4? Come on Google. Sort it out

my impression is that almost nothing involving Bluetooth functions as it should currently on the N4. I can't even get a mouse to work. what a shambles! it's not as if BT is some new technology. this all better get sorted out in 4.2.2.

If I'm not mistaken Google moved to a new Broadcom b/t stack. Yeah, good move! And I agree, b/t has been around for like what at least 10 years now? You'd think that getting track info should be a given by now. I have a crappy old LG phone running Gingerbread and it has no issues at all.

Bluetooth
When I got the N4, I connected my helmet headset to it and everything seems to work fine. My headset supports ad2p music and phone. Both connected and both worked, including play controls. Not sure about the audio quality, I didn't test it long enough After I flashed Jellybro (CM 10.1 Kang) Music connects, but phone goes on a connect/disconnect loop. Audio needs further testing, can't tell if the left side is off because of the bluetooth or not. Controls work most of the time, every now and again playback will decide to pause itself and sometimes the play command doesn't work. Haven't had a chance to flash stock CM 10.1 nightly yet either.

Play/Pause Works Inconsistently
Has anyone had this issue?
I am on stock 4.2.2, I connect with my car stereo no problems. I use to be able to just hit play/pause on my car stereo and it would just play music from Google Music. Now, sometimes when I hit the play/pause button on my stereo, it won't play. I have to manually hit play from my phone. After initially doing that, then I can hit play/pause and the control is there. I haven't had the problem since I got my phone on Nov 14th, this issue just started to happen. I notice this after installing Light Manager, but I have uninstalled it and still the issue is there. It is inconsistent, but the issue is more often than not.
Thanks in advance for your input.
Just reiterating, stock Android does not show artist/track info, it is not in the protocol, but you can skip tracks or go back to previous tracks. If it is important to you, you should root and get a custom ROM, not sure which ones for N4 has it though, been too happy with stock to root.

About time, Google:

[Q] Hands free bluetooth issues (Merc B Class)

Hi all
Sorry if there is another thread with this already but I am at the end of my tether!
I have a Galaxy S4 with Android 4.2.2 and am having problems when paired to my Merc B200 with Audio 20.
I believe this may be a common problem but I just need confirmation from someone in the know.
ISSUE:
I can pair with the head unit no problems, but when I make and receive calls, there is no audio. Apparently the other end can hear me, but I am unable to hear them.
Audio is on max, both on the phone and the audio 20.
Any ideas? Is this a software issue?
I did contact Samsung, who obviously told me that this was down to the car manufacturer and MB told me to buy an older phone (great advice!).
My wifes Iphone 5 works flawlessly, as did my Iphone 4s.
MB seem to be under the impression that a car firmware update will no resolve the problem and basically I am scuppered. Surely bluetooth should be backwards compatible!!!
Cheers
Andy

I got a blackberry to work with a mb car kit a while ago, not sure of the symptoms the user was seeing but he was pairing from the phone to the kit. I tried pairing the phone from the car kit and it then started to work flawlessly.
Sent from my iPad using Tapatalk (how ironic is that eh)

might be a similar issue
Not sure if it's the same thing but I'm at a loss as to what to do. I bought the Jaybird SB2 bluetooth headset. I've read elsewhere others have had issues connecting to Mac's (I have the same connection problem with my Macs) but they worked fine with my old Galaxy S2 (when it had pre-jelly bean rom). As soon as I upgraded the sounds cuts out after a couple of minutes although the player says the music is playing. I can get it to work again for another couple of minutes by disconnecting then reconnecting the bluetooth. I then flashed a custom JB rom (supernexus I think) on the old S2 and everything worked perfectly. I've just got my stock S4 and the same problem with the bluetooth keeps happening.
I can only think it's a software problem since the headphones work perfectly with my Nexus 7 and my old S2 with this custom rom but I can't find anything online elsewhere recording the problem. Not really sure where to turn for help since I doubt Samsung will care.

Unsure if 100% related, but I've had some issues with BT on my Subaru Outback ('13).
When I am (simultaneously):
1) Charging
2) Connected to my car stereo via Bluetooth
3) Playing music (using default GS4 music widget)
4) Navigating w/ Google Navigation
The Google Navigation voice cuts out half way through giving the direction.
"In 250 feet, turn right onto" ... ... ... ... nothing
It's really horrible, especially because this is the PRIMARY use for my phone (car audio & nav).
Update:
Winamp doesn't interrupt nav, but I lose BT controls on steering wheel.
AVia doesn't either and keeps BT control functionality.
All music players I've tried, however, just seem to crash at random...
They either stop altogether or think the music is still playing but no audio is on.
All of this is resolved by using Aux instead of BT.
This is what leads me to believe it is BT related.
Anyone with experience or help here, that'd be awesome...

I've had a breakthrough with mine
I installed an app called 'Soundabout' from the playstore that reroutes any audio to a BT device, this did the trick, I now have audio both when making and receiving calls.
It also works for a2dp streaming issues.
The odd thing is though, I deleted the app afterwards just on the off chance that it fixed anything in the background.... And it did! My BT audio is now working seamlessly without the app!
I am currently running a flashed stock rom (XXUAME2).
Hope this helps others

Hi,
I have the same issue.
I have just got my new Galaxy S4, everything is working fine except the Bluetooth. I am having trouble to use the Bluetooth on my 2011 Toyota Car corolla. I am able to connect to the Bluetooth, and play music but problem with starting to make a call. when I say "starting to make a call" means I can make a call, but the receiver can't hear me and I can't hear them neither. I was able to answer the call or hang up, everything is working fine except no voice come out from the speakers.
The funny is it will work if I use Apps to make a call, such as Skype, viber.
I can't find any solution so far.

4ndynic you're a legend! My wife got an S4 and it didn't want to work properly with our Mercedes with the native bluetooth. I installed Soundabout (non Pro version), went into Bluetooth Behavior, turned on (Dynamic) Media Audio Usage, and now it works perfectly!! I especially love the fact that the alerts for SMS etc still come through the phone.

It appears that the setting may revert if you turn bluetooth off and back on again. After doing that, I had to go back into soundabout and untick then retick that box. Can anyone else confirm this behaviour? It certainly appears to be a default setting in the operating system causing the issue, which means it may be possible to fix with a patch, and Samsung should certainly be able to fix it in a future update.

I thought Mercedes would contact the SoundAbout email address about getting that to work, but alas....I've gotten no email yet.

it might be your rom version, tried it here with 4.2 and 4.3 and works without any issues and no need to install additional software.

Bluetooth issues in car

Hello everyone, I am borrowing a oneplus 2 from a friend while my phone is in for repair, I have had it for about 12 hours now and have found an issue with the Bluetooth, when connected to my car (its a JVC aftermarket stereo) it loses connection every 30 seconds. I have tested the JVC with my girlfriends Sony xperia m2 aqua and it works flawlessly, has anyone else had this issue?? And if so, how did you fix this?
Thanks

Yeah I dont have connectivity issues but I don't get any audio controls through my car or song info. I think it is all software related issues.

I can report that the oneplus 2 have problems connecting to MB car audio system. Phonecalls work but music from the phone to the car don't work. It is a new MB c-class 250.

I also have BT problems with my car. My car has BT for phone calls only, so I also use a BT to 3.5mm adapter to my aux input. When I connect to both, it keeps pausing my music every 5 seconds. Once I disconnect from the car BT, then the music plays fine. Very annoying. No problems with any of my other phones.

@Mackis Haven't tested music on mine, but I have a 3 month old MB A180 special edition. Voice working 100% I use the usb port in the car and play music from the usb drive. Much better than bluetooth, you can change folders etc, were you cant on bluetooth!

I'm experiencing the same issues. I'm an authorized dealer for Volkswagen and Škoda and cross-tested several radios this morning. Very annoying.

I have a Clarion fz709 and the OPT works great with it on BT. The radio is old as dirt too. Works for calls and music.

Several issues on BT here, too. The connection to an Audi MMI and phoning working properly, but no audio controls or Phonebook synchronization. In a german board the app Bluetooth Phonebook is reported to solve the problem with the synchronization. Will check that later on today.

hi, i've bluetooth problems too. audio and calls are perfect, but my contacts are not transferred in the radio... this is so uncomfortable! anyone have same problem?

These are two different issues with BT and car radio:
case 1: can not or not correctly sync contacts (in my case all numbers where labled 'mobile' and some where missing).
case 2: no support for audio control while playing or no playing at all
possible solution for case 1:

There may be a solution for case 2 but I do not know of any nor can I test it because the Parrot Asteroid (Android Car Radio) works without a problem for case 2.

These are two different issues with BT and car radio:
case 1: can not or not correctly sync contacts (in my case all numbers where labled 'mobile' and some where missing).
case 2: no support for audio control while playing or no playing at all
possible solution for case 1:
( all credits for discovering this app goes to psychonaut at Android-Hilfe.de Forum )
First check out the trial version to test if it fixes your problem!

Hi,
with my Renault Megane 2010, the RadioSat, now, Works fine, after the update to 2.1 OxygenOs.
My Bluetooth problems gone away.
Now I have full functional hands free system. Tanks Oneplus.
Regards

Yes! I also can confirm my posting from Sunday, that the App Bluetooth Phonebook solves the issue of not transferring the phonebook (at least for my Audi MMI).

Problems with Volkswagen Discover Media Pro too:
- address book not syncing
- cannot play audio
- not able to make calls
however:
- i can see text messages (SMS)
- i can see the call list/history (obviously i only see telephone numbers, not the contact names, since the address book is not syncing)

I'm experiencing the same issues. I'm an authorized dealer for Volkswagen and Škoda and cross-tested several radios this morning. Very annoying.

My new Skoda Octavia isn't working with Oxygen OS 2.1.0. Connection works for 5 seconds and then the whole thing hangs. Good-news is that this is indeed software related as CM12.1 CustomRom from Garak works with Contacts/Spotify/Telephony

This will fix all your problems guys!
Bluetooth Skipping Fix: if you have a conflict or issue with your bt add this line to build prop using root explorer..thanks Shrek and reaper

Indeed: different rom (SlimLP for me) works flawless. Calling, text messages, play music, everything.
Now let's see how stable it is and how the battery lasts.
I wonder if the build.prop fix mentioned above works. Hope we can get some confirmation about that. That would be a good alternative.

Phonebook sync doesnt work for me either, but music and controls do - no song infos, but my car never showed those. Kia ceed 2015.
