[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.

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.

Do you have 'Soundabout' in your app store? Solved my problems.

Hi,
I did try that, didn't work.
May I ask your setting on your Soundabout?

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.

Set phone call audio... To bluetooth mono
My phone is not rooted either, had to remove it for certain apps. I'm running XXUAME2 stock

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.

Will do some testing and let you know, I deleted the app and it carried on working until I rebooted so kind of the same thing! Defo something that could be fixed with an update, just need Samsung to listen! If only I knew a little more about Android development!

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.

[Q] Bluetooth woes ,, opinions needed

Have a stock unrooted N4 running the new 4,4,3.
Updated to 4,4,3 solely in the hope it would solve the bluetooth disconnects experienced. Note I did not have 'stuttering' or the like, just solid disconnects which would then auto reconnect in 30-60 sec unfortunately stopping my music app which would then need to be restarted and since I primarily use the BT on my bike or motorcycle it is obviously a pain ....
!!!!!!!!!!!! the update not only has not stopped the disconnects it has now introduced stuttering on occasion (not all the time) ....
Here's where I am at:
1. Live with it until Google finally realizes IT'S A PHONE not a camera or whatever and solves the BT problem or gets the BT folks to do it. (really can't believe they can't solve this or is it just an N4 problem?)
2. Root the phone, install TiBU, backup, wipe and install 4.4.3 factory images, reroot and recover stuff from TiBU ... all this in the hope the BT problem goes away ... chances of this?????
3. Give up and install CM which people say does not have this BT problem ... true??????
Thanks in advance to all for your help and opinions ..........

Could it be the BT device itself? Does it work like a charm with other devices?

That's a great question and I am sorry I did not include the info in my original post ... the problem is evident with several different BT devices and these same BT devices work fine connected to other things ..... but not with the N4

Has it always been stock? Perhaps your BT adapter in the device is faulty itself. I've ran two different headsets off of mine in the past year as well as connected to my PC and other phones with no issues at all. I've been rooted running beanstock right from day 1 though..

Yup ... always stock ... when new on whatever version was current then (can't remember) did not have this problem and BT worked fine ........ when they went to the 'low power' BT solution it started.

Was really hoping this update would solve the disconnect problem.

[Q] Bluetooth disconnecting on i9505 running CM11 later than 2014-08-04

Hi!
I have been running CM for years now. For the first time the nightlies aren't working good for me. The cm-11-20140804-NIGHTLY is working great, but as soon as I installed any of the newer my bluetooth starts disconnecting. For instance, the cm-11-20140817-NIGHTLY caused the phone to restart several times a day. It also caused the bluetooth to disconnect and the wifi acted very strange.
The latest rom I tried was cm-11-20140831-NIGHTLY. The bluetooth disconnected almost immediately and I went back to 0804.
Any ideas?
Thanks in advance!

Hi,
I've made similar discoveries regarding only bluetooth connections. :crying:
I'm using nigthlies for a long time.
With cm-11-20140724-NIGHTLY-jflte S4 GT-I9505 and my car (BMW E61, 2006) connects perfectly. Later nightly roms aren't working with my car.
Any hints?

You can use the latest Snapshot: cm-11-20140804-SNAPSHOT-M9-jflte.zip
In this one bluetooth is working correctly.
You can download at cyanogenmod.org

Same thing on SPH-L720
I noticed that the same thing happened with my Sprint Galaxy S4 (SPH-L720), on Cyanogenmod and Paranoid Android. I didn't even think to flash an older version of the ROM. Guess I'll do that since I miss having Bluetooth connectivity in my car.
Does anyone know why this started happening in recent builds, though? I haven't seen anything about it.

Latest snapshot is cm-11-20141009-SNAPSHOT-M11-jflte and still has the problem. Connects but disconnects after a couple of minutes. Both in my car and my wife's car. Very annoying.

Has anyone tried the newest M12 snapshot to see if resolved their issue? I have the same issue on multiple M11 snapshots.

I have the last mahdi rom and use a bluetooth speaker for my bath. I don't have this problem. I don't know maybe they have another bluetooth driver or something

CM11 M12 Bluetooth/WiFi Issue - Fix?
Apologies for the hijack, as this may not be entirely similar to the OP, but the solution could help.
I was experiencing wifi disconnects when I would toggle on bluetooth, when using CM11 M10 or higher.
With a clean install of Cm11 M12 (reset/new user + formatted /system), I finally worked up the courage (and kinda' understand what it is I have done) and updated the bootloader (not sure if necessary) and the GSM/LTE modems to the latest - XXUGNK4 - from here http://goo.gl/RziHz1
I was previously on XXUFNC6 (from the stock ROM), went to XXUGNI2 (closest to my country based on this thread http://goo.gl/TQi3gz) but that did not work either. So I went straight for the jugular, and installed first the bootloader, then the dual modem pack for XXUGNK4.
So far testing has yielded positive results.
Streaming audio (320mbps) via BT plus downloading some ISOs from MS (speed between 550KB/s to 1.01MB/s), and so far no issues.
Not saying this is going to work for anyone else, or solve the OP's exact issue, but it seems to for me.

Does the samsung galaxy s4 auto disconnects bluetooth?

Hi people,
I have a galaxy S4
Android version 5.0.1
Model GT-I9505
Orriginal ROM
I bought a Philips BT5580 bluetooth speaker.
the connections is easy but after a while it auto disconnects bluetooth,
I also tested this with a philips BT6000 same issue.
does the s4 has some energy save mode for bluetooth or is this a philips issue?
my powersaving option is turned off by the way.

Probably a combination between the firmware and the speaker. Not much you can do besides trying to switch roms/modem.

hmm ok I'll try a other modem,
Do you have any suggestion what modem I can try?

NEver mind It's mot my phone, it's the speaker.
I tried the same thing with my Ipad and it also disconnects.

Bluetooth connectivity issue in BMW

Hi all! My boss has the Edge + (as do I) and is having all sorts of issues with the bluetooth connectivity in his BMW. It keeps dropping in and out. The calls don't drop; the bluetooth drops and then reconnects. He's a business owner and makes tons of calls from his car, so as you can imagine, this is quite frustrating (and embarrassing).
Anyone else having similar issues?????
Appreciate your help.

I'm actually having similar issues now in my Ford Fusion. It will connect, but won't let me make calls or listen to music. When I attempt to play music it will say that BT media has been disconnected. Upon checking the status on my phone the media turns off, but the phone is still connected. However, neither really works. It's frustrating as it worked for several days when I first got the phone but then suddenly stopped.

Audi mmi works great. Maybe call your dealership and see if they have a update for the system?

My advice for the BMW is to check the firmware update for the specific model of car of your boss on the BMW website
It is not very much intuitive but I can assure there is this possibility and also the new firmware download is possible
I've been using a Note 3 for two years on my BMW 530 and at the beginning with their old firmware I had similar issues, then it was very stable with both music and phone calls. Now I'm using the Edge + without any trouble

No problem with Bluetooth on my Toyota Auris Touring Sport HSD, sometimes sms are not showned but they are well received by the car when I check them, and calls work fine. So as dengi_it told you maybe a firmware issue with your car.
I heard somewhere BMW and Mercedes will have some discussion to link iPhone and cars together maybe they won't support Android phone anymore in the future :s.

Thanks, all. Going to pass along this advice. Appreciate it!

Tell him to buy a new car!

Yes, I have the same issue in my 2015 M5. Bluetooth is essentially unusable after the latest update (OH5). This phone is going back.

UPDATE: He factory reset his phone and it seems to have fixed the issue. ::fingers crossed::

This is my second S6 Edge+. I thought it was possibly a hardware defect with the first but after the second one I am led to believe it's a typical shoddy samsung update. A factory reset will fix the problem for a few days and it will begin again.
Picking up the new iphone 6s+ on Friday. I've had enough of the bluetooth issues.

Sorry to hear. Good luck!

Works fine in 2011 Hyundai Sonata.

I am having a lot of Bluetooth issues on my Elantra. Works for few days and then it just fails to connect and I have to delete my car from my phone and from my car stereo just to get it to connect. It is a freaking pain in the butt. This is my second Galaxy S6 I have gotten and it seems mostly to be a software issue then a hardware one.
