I can't see any option anywhere in my SGS2 to set a BT paired device as "authorized". Every time I enter in my car I've to manually select the BT device and start manually the connection.
I searched in the forum but didn't find answers.
I also tried to look at the filesystem and I found auto_pairing.conf file in which there are a lot of BT manufacturer brands listed in sections like "black list", "white list", .... Is it possible I need to manually modify this file to include my BT manufacturer in the white list section? It sounds really strange!
Is there any other way?
I'd love to know that as well.

Update
I manually modified auto_pairing.conf file adding my car BT manufacturer without any success (I added it in white list with the name already mentioned in the file, so I think that's not a problem of brand name).
My SGS2 continue to ask me to manually select the device to connect to, even if only one BT device is available (car handsfree).
I have the same problem, which i didn't have with my Nexus One running Cynogenmod ROM. I keep my Bluetooth on all the time or most of the time and i would like (like i had in nexus one) when i turn on my car (with Sony MEX-BT3700U car stereo with Bluetooth) that the phone auto-connects with the stereo in a minute or less (or with my plantronics headset when i turn it on), but no, every time i have to go into bluetooth settings and connect on the paired device and then it's connected.
I heard about few application that could help but it would be nice to have it as native function on the phone. I haven't tried these apps yet but if anyone want's to try they can be downloaded from the market, firs is free, the second is not.

If anyone can help it would be greatly appreciated
I don't have this problem at all, on any ROM I've tried stock or not. Is your stereo also set up to auto-connect? And is it your phone or your stereo that's refusing the auto connection?

Stereo doesn't have any options, same as Plantronics headset (only ON or OFF), that means that with my old nexus one running CM (or Nokia n95 8GB) when the bluetooth is switched ON and i come near stereo or headset they connect automatically in about 30 seconds max, with my SGS 2 that doesn't happen, i tried everything but it wont auto-connect until i initiate the connection from phone manually.
I have to resolve this because it's killing me !

I wonder if that's the issue; IIRC it's my stereo that I've told to connect automatically rather than my phone. I'll verify on my commute home today.
Mine auto connects to my JVC car head unit, but doesn't to my Belkin Tunestage. No idea why. As it happens, this suits me but it'd be nice to be able to control it.
And the commute begins. The auto connection is an option on my JVC deck, no such option on the phone.

The stereo is recognized same as Plantronics and that is as a head set, but it doesn't want to automatically connect to either of them, every time i have to initiate the connection. There is one way to connect it (partially automatically ) but that's not the solution - i have to turn on the bluetooth on my phone before starting my car, then when phone is in searching mode if the car is started (stereo turned on) then it will connect automatically, if the search mode (that is active for a short time after turning the bluetooth) ended before i start the car (for instance if i keep my bluetooth on all the time on my phone) then it wont connect automatically.
Am i any clearer about my problem ?
I hear what you're saying but it appears that auto connection is initiated by my stereo. If I turn auto connect off on my stereo there is no connection until I tell my phone to connect. I don't see anything on the gsii settings to have the phone auto initiate the connection. I have a recent JVC deck fwiw.

I will check one more time is there any bluetooth settings on my car stereo, but i'm 90% sure that it doesn't have, because this is the first phone that doesn't connect automatically.
I have had similar issues with mine, it will pair with my Kenwood DNX520VBT but wont auto connect.
however i now have a workaround
Turn bluetooth on your GS2 first, then turn on you Radio. once my Radio boots up it initiates the connection and auto connect works.
if i turn on the bluetooth on my GS2 after my radio it never works.
ive got a sony bt3700 stereo, it connected perfectly with my samsung wave, i just upgraded to a galaxy s and i have to do it manually every time so its not the stereo.
Same thing happened to me, old nexus one with CM7 is connecting ok but i have to connect SGS2 manually or make sure that my bluetooth is ON on my phone before i start the car.
I may have the answer......
Hi,
I have a sort of work around.
My Pioneer head unit refuses to auto connect to my SGS2 and I have to do it manually (I connect from the radio in 4 clicks but thats not the point). This was driving me nuts as previous handsets I owned connected within 5 seconds of being in the car.
I then discovered ROMS and went for the Criskelo ROM and it put me on Android Version 2.3.6 (Not sure if that made a difference or its actually the ROM).
Now with that sorted I found that I have an extra function in my bluetooth settings. When I make the device visible I can then choose the visible time-out length. If I set this to NEVER then I have no problems connecting to the headunit everytime I get in my car.
The only problem I have with this is that I pop my phone into Airplane Mode each night and because that disables the bluetooth it loses the time-out setting so I have to put the time-out back to never each morning.
With setting the time-out to never I'm not sure what battery drain is like because I'm constantly on my phone and my battery depletes rapidly anyway but it seems like a fix for now.
I hope this makes sense and helps people out until a proper fix becomes available.

Hi All,
Sorry for bumping an old-ish thread, but it seemed the most appropriate thread, and better than creating a new one of the same topic!
This is what I believe to be true:
*IF* Bluetooth is enabled on the GS2 (and the phone has previously been paired with the car headunit) then when the car is turned on, it will auto-connect to the GS2
*IF* Bluetooth is NOT enabled on the GS2 (and the phone has previously been paired with the car headunit) then when the car is turned on, it will NOT connect to the GS2 (understandably!).
*IF* the phone has previously been paired with the car headunit, and the bluetooth on the GS2 is enabled *AFTER* the car has been started, it does NOT Auto-Connect.
From this, I assume that when the car is powered on, it searches for previously paired handsets in order of most recently connected first. If it finds one, then it WILL connect.
Now:
If I leave Bluetooth enabled on my phone, the battery is significantly depleted my mid-afternoon.
I've started using an app which uses the "rough location" (not GPS) to monitor where the phone is located. If it deemed to have moved in X period of time, then it enables bluetooth.
This is great, and works a charm ... BUT it does mean that bluetooth stack on the GS2 is enabled AFTER the car has been moving for a period of time, and thus does NOT auto-connect.
What I've been searching for is:
"When BT stack is enabled on GS2, can it look for previously paired devices and initiate the connection itself?" (Rather than the car connecting to it?) Is there a script or app to do this?
Hi WTFH,
I think it might be more headunit specific. I always have my bluetooth on but it wont connect automatically to my headunit unless I have it set to constantly discoverable (on the handset).
I also use a power saving program called Green Power Premium which will cut bluetooth/data/wifi after a certain amount of time when the phone is in a sleep state. Its great fro saving power as my phone isnt constantly looking for a wifi signal (I don';t use it to control my bluetooth though as I need it on for my car).
Hey DJ_sploits,
Thanks for that ... Yes, I understand that some headsets do not auto-connect to the GS2 if the phone is NOT visible.
But what does seem to be constant is that the GS2 will not auto-connect to any of the headsets if the bluetooth stack on the GS2 is enabled AFTER the headset has come online and available.
One workaround I'm thinking of is:
Enabling a profile which says "When connected to a power source (I'll have to use the power adaptor) then enable bluetooth". Connecting my phone to the power first before starting the car should enable the BT stack before the headset tries to connect.
In fact I could extend this to say "Only enable bluetooth when using power adaptor, and not connected to wifi".
It's still a pain to do this though, as I tend to just jump into the car and don't want to faff about with connecting this and that.
The only other work around I use is to set the visiblity to constant (depending on what android software version you are on). My headunit always picks the phone up if I have it setup like this. the only thing with that is it will eat the battery even more (which is annoying considering there are other phones out there that constantly have their bluetooth on and you never see the battery getting hammered).
The only flaw I can see in your method is the fact you need a power source to knock on the bluetooth. Great for powersaving but it would then mean you would have to remember to connect it to a car charger everytime you got in the car (not too bad if you have it constantly plugged in to the cigarette lighter) and as you set this can be a bit of a faff.
The only way I can see in sorting this is using a power saving app but having your visibilty constantly on for the bluetooth and then we just hope it doesnt eat the battery too much (not to bad for me as I have a charger at work but could be a pain for others). The only problem with this (apart from the battery issue) is that if you knock the bluetooth off or knock the phone to airplane mode (as I do at nights) then when you knock the bluetooth back on it forgets that you want it to be constantly visible so you have to go through the settings and check the box
Hello,
I have upgraded to Android 4.1.2 and my Kernel is JZ054K.I9100XWLSD. Since the upgrade I face problems with bluetooth. Everytime I conncect via bluetooth to our car telephone system (Audi), I get connected. After 30s I get reconnected than connected again. I had version 4.0.4 before and did not have any problems with bluettooth connections to my car. Does anyone have an idea? Does the 4.1.2 in general has this problem? How to fix it?
Thank you very much for any suggestion ort support!
That's strange. How did you update? Does is connect as rSAP or only with Handsfree profile? Did you already try to remove the pairing from the car and to do a new pairing?
I updated three days ago using KIES from 4.0.4 to 4.1.2 and I do not have any problems with connection to my VW FSE Premium. Everything is working like before I didn't even need to do a re-pairing, the old configuration was still working.

I updated via WiFi. Re-paring was not necessary. I switched not to visibility from 2 Minutes to always. Need to see, if this helps.
I do not need to set/change the visibility on my phone. I switch on bluetooth and when I enter my car, the car "takes" the sim card. When I switch off bluetooth or leave my car, the phone is getting access back to the sim card.

I've had similar issues with my SGS2 on ICS and now with 4.1.2 (XXLSJ). I'm convinced the problem is a combination of the phone's current processes and how often the car kit retries to connect. I have a Parrot based bluetooth kit factory fitted in my 2006 Mitsubishi. It usually connects within about 20 seconds of starting the car. It often won't connect for about a minute and sometimes doesn't connect at all (maybe 1 in 20 times). When it doesn't connect, I turn off bluetooth in the SGS2 wait about 15 seconds and turn it back on. It usually connects again without touching the car kit.
I've noticed that if I unpair the car kit at the SGS2, the car kit will try to reconnect about once a minute and the phone makes a noise to tell me that something is trying to connect.
Recently I took a vacation and rented a 2012 Toyota Camry and paired my SGS2 to its bluetooth. The phone connected faultlessly very time, there were no issues.
My theory is that if the phone is busy with some process or another when the bluetooth kit tries to connect, it misses the connection. If the kit retries several times (I'm guessing the Toyota kit did this), then there seem to be no issues.
I can only guess that if the SGS2 bluetooth stack is given a higher priority it would be less likely to miss the connection. Clearly that's impractical because bluetooth only needs to connect (maybe) 3-5 times a day and may exclude a more frequently used process.
Just my 2 cents worth - I hope that helps

Actually, we own two SGS2 phones: Both pair with our Audi telephone kit. The first reconnects after 30 sec./ 1 minute and then reconnects. The later stays connected. However, if I try to use the phone to dial a number via the Audi telephone unit.....the Audi telephone unit starts to dial and then stucks. The first phone is able to dial.....as I have seen in the web others seem to have the same problem with SGS 2 4.1.2. I even bought BLUETOOTH KEEPALIVE...no succces. With version 4.0.4 neither of the phones had a problem with paring with the Audi device. Any other ideas?
Same for me
Im also having the same issue, I have a SEAT Altea and after upgrading to JB on my S2 i have exatly the same issue.
Connecting to the Blue Tooth now takes a lot longer than previously and i get a rapid reconnection about every 30 seconds or so (could be slightly longer i havent measured it). There is no disconnect sound from the hands free though only a conneciton sound.
Please post if you find a resolution to the issue.

Problems with Bluetooth
Hi All,
I have the same problem. I upgraded to 4.1.2 recently and immediately after all was OK. However now it has developed a new problem.
It will connect to the Car Bluetooth and will play music however the minute I start a call it will only use the small speaker designed for when you hold it to your ear. I will not allow me to press the headset button and will not automatically switch to headset/Bluetooth. This is seriously irritating and I have tried all the usual options of rebooting and unpairing etc. but to no avail...
Your pearls of wisdom would be gratefully received

I report the same issue between my SGS2 and my '04 BMW 3-series.
With the 4.0.3 ICS no problems: the phonebook is shared correctly and visibile with the car, without loosing the connection.
Starting from 4.1.2 JB I'm not able to keep up the connection for more than 30 seconds, and I cannot read also the phonebook: in this way the phone cannot be used in the car.
The only way to have JB and the bluetooth working togheter is to install a custom ROM (4.2.2 SuperNexus or RootBox 4.2).
Try it!:good:
Install File Manager which can access system files
go to System/etc/bluetooth
in file called main.conf add
IdleTimeout=0
save file - it worked for me
Greetings!
Has anyone else noticed any conflicts with simultaneous bluetooth connections to other types of devices while the Gear S is paired to your phone?
I have a Note Edge from T-Mobile and the Gear S from T-Mo as well. In my car (Chevy Volt) I have the factory infotainment system with navigation, bluetooth, etc. I noticed that at seemingly random times, when I had the phone paired to the car and was either in a call or streaming music, the connection between the car and the phone would be lost. I chalked it up to an issue with the Bluetooth profile stack GM was using and used a wired connection.
Then, I experienced the exact same problem in my truck with an Aftermarket Pioneer head unit connected to the phone. It too would drop the connection at random intervals. That caused me to start to suspect the Note Edge or the ROM I was running on it.
Yesterday, I accidently left for work without my Gear S. Guess what? The connection didn't drop once during my 45 minute commute. So today, I turned off the Gear S before I left work work, and I never lost a connection.
This tells me there is some sort of an issue with the Gear S. Has anyone else experienced this? If so, have you found a fix? To the best of my knowledge, I am using the latest official firmware for the T-Mo Gear S, and I just updated the Gear S app for the phone through the Samsung store, etc.
Thanks!
It's a long post - sorry please bear with it..........thanks
Performed a firmware update couple of weeks ago see thread: https://forum.xda-developers.com/mate-10/help/mirrorshare-stopped-t3731964 and all seem well until 2 days ago.
All revolves around bluetooth:
Background:
I have 3 devices which I use regularly for BT connections
Huawei Watch 2 (came with phone )
Car (phone calls only)
BT Headset (Sony SBH52) - used for Music only (my car will not play music over BT so I have my BT headset connect to the AUX port)
Limitation:
A phone can only connect to 2 BT devices at once (as far as I know/have witnessed)
Scenario
Phone is always connected to watch
Get in car - phone auto connects to car BT.
I manually connect phone to BT headset - it drops connection to watch so now my phone is connected to car for phone calls and headset for playing music.
GREAT This works for me and all is OK...and has been working OK for last couple weeks. (I used to use this method with my Nexus 6P and had no issues - I didn't have the smartwatch2 then)
Up until 2 days ago
Phone kept losing connection to BT headset - it would connect and then immediately drop
I couldn't do anything in BT settings on my phone (such as disconnect or forget).
Did all the normal stuff - BT on/off : headset on/off - no change.
"Forgot" BT connection for car.
Headset still had same issue.
Finally removed connection for headset.....reconnected to car BT.
Car BT then started dropping
Finally 'forgot' BT connection for car
Watch appears connected OK however it used to display in the drop down menu what BT device I was connected to - now it doesn't.
The BT symbol also used to have little marks at the side of it to show it was connected to a device - now it doesn't
When I look in BT settings on phone I see my device listed however I am unable to "forget device" or tell if it is connected - only way I can tell if connect is check on the settings on watch which say that it is paired and connected - plus I do get all the alerts on my watch so it's definitely connected and working.
I have factory reset watch, phone, car system and BT headset - still have the issue
Any ideas?

It was a bundle with Vodafone UK - first 1000 customers to order phone on a monthly contract received HW2
Further testing/info
After another factory reset of the phone and a 'disconnect & reset' of the HW2 and seem to have got it working'ish....
So -
Car BT connects fine and displays in BT settings on the phone as connected
Sony SBH52 headset - connects fine and displays in BT settings on the phone as connected
HW2 - although it connects it does not show in BT settings on the phone as connected - also unable to do anything on the settings for it :|
I'm not convinced that the disconnect & reset is actually performing a factory reset of the watch.
Perhaps this needs posting in the HW2 forum - is there one?
hi guys. came to this site because of the same problem.
Found a fix - reset network settings.
after going into settings menu and resetting network settings,
connect to your bluetooth device again and it should work (at least for me)!
So here's my concern. My stratos with the latest firmware when not in the airplane mode connects to the phone when phones wifi and bluetooth are both on (using bluetooth for wireless headphones) and after im done with headphones or something that uses BT besides watch I turn it off. Same goes for wifi. But then i noticed that my watch is still connected to the phone in amazfit watch app. I can see battery status, watch uploads sport info,I even can test for notifications and there you go - its shows in watch. So I am little bit lost here, how does these two talk between them if bluetooth and wifi are both off? Had pace few months ago and i havent got that problem. It wouldnt be a big of a problem but i noticed slighty drop in battery life. Phone - xiaomi mi a1. Both international versions.
You gave the the app permission to turn Bluetooth on.
