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
ICS Bluetooth on i777 SGS2 is acting up on my stock Subaru handsfree radio.
This may be because the Subaru radio is flakey, I don't know. The bluetooth connection is stable and reliable with GB roms and a Nokia Symbian phone.
My observations are based on 1.3, 2.0, and 2.1 4.0.3 roms from Shoman94, and 4.04 AOKP from task650. Kernel and Modem changes seem to make no difference on this issue.
The biggest issue for me is that the bluetooth connection to the car stereo will drop when the "deep sleep" mode is entered. The connection starts again if the phone is awakened.
The connection will stay connected if bluetooth is active with music or other operations.
The connection will drop during a long phone call or the phone is not being used.
I have read of problems with other ICS devices having issues during "deep sleep",
SOD's and reboots mostly.
Others have tried to prevent these issues, by using SetCPU profiles with freq. changes, limited success.
One App that has helped is SoftLocker. Designed for Tablets with deep sleep issues, it allows me to block deep sleep. Blocking deep sleep allows my phone to stay connected to the car stereo via bluetooth for handsfree operation. It will chew up the battery like this, but I can charge in the car.
Yep. Happens to me too. ICS ShoStock 1.3 and 2.1.
I'm on 2.1 and my Chrysler sound system has had no issues. My previous phone had shostock2 v. 1 - 2 on it and no issues as described either.

I use AOKP and my Bluetooth has no issues with either of my vehicles.
And yes this is the wrong thread... it is for devs. You should be in general or q/a

No issues with connecting to my car with SHOstock2 ROMs.
I have an occasional disconnect with my GS2 and my Explorer with myfordtouch/sync. I don't think it's happened sync I switched to AOKP compared to Sho2, however.
I don't really pay much attention to it.
never had this issue. so i see the that the OP has the issue. where is the DEVELOPMENT thats going on to fix this issue then? This is the DEVELOPMENT thread after all. this should be in general bro.
Zero issues with ShoStock2 v2.1 or aokp on my alpine kce400bt in my 94 Silverado or any issues with any bluetooth device at all...
HTH,

Both my pioneer head unit, stereo headphones, headset, and Nissan factory system have no disconnects when in deep sleep. Both my sgs2's.

This sounds like the same issue reported in another thread here a few months back. I had the same problem as the OP of that thread, where the BT would disconnect after a few minutes (10 maybe) of no phone activity other then playing a song. I used a dedicated BT speaker which would function correctly when paired with a PC, but auto disconnect from the phone. Although everyone here seems to be dismissive, it is an issue that other users have encountered as well. I'm using UnNamed 1.3x and haven't found a solution (but have reduced my dependence on BT).

Yeah. This is real.
I started getting the issue once I switched from GB to ICS ShoStock2.
The car is an Audi A6 2007. If I connect the car speaker to the phone via Bluetooth and my conversation lasts for more than five minutes or so, the Bluetooth connection is severed.
It doesn't end the call, so I can pick the phone up, turn on the screen and the Bluetooth reestablishes connection. But the conversation is interrupted.
Again, this didn't happen before and is easy to reproduce.
This problem is likely in the bluez stack. From GB to ICS there were quite a few changes. One of them has just left behind some of our hardware. Since most people don't have trouble, this probably won't get fixed.
One more observation,
When charging in the car, the Bluetooth stays connected. This seems to be because deep sleep does not occur while connected to the charger.

Do you keep your BT on constantly? A thought that just occcured would be to use Tasker to switch the CPU profile to one without sleep when BT on and revert back on BT off. That on charge find could be pretty useful as well.

Thanks, I do run bluetooth continuously and Tasker may provide a way to workaround this. I'll update if I figure it out.

I have the exact same issue in my Audi A8 and A6.. will try Tasker and the charge-trick.
I am still using SoftLocker to disable deep sleep, or using the charge cable in the car.
The trick with Tasker is to figure out a way to lock out deep sleep.
Here is what I'm testing today,
To use Tasker, the plugin for Tasker, Secure Settings, and the Helper app.
After installing Tasker and Secure Settings apps, run Secure Settings. On the "Settings" tab, under "Helper", tap the option to install Helper. This will install Helper, and require su permissions.
In Tasker, I added a profile for BT connect to car, with a Secure Settings/Helper task for CPU awake only, Manual ON.
Next, added another profile to Tasker, BT connect, checked Invert (Should activate on BT disconnect from car), added Secure Settings/Helper task for CPU wake only, Manual OFF.
I'll post later if this works as I intend.
The method above using Tasker works. My phone is not entering deep sleep while connected via BT to my car stereo handsfree system. When the BT disconnects, my phone is entering deep sleep.
Tasker has a trial version if you download it directly from the developers website. This may also be purchased directly from him, and may save a little over the Market version.
Have to love when problems and solutions come together like this!

Hi all -
I have a Cobra iRadar Detector. It connects to the phone via BT and that is how and were you see your speed and other general radar detector stuff.
I also have a Motorola SD10 BT headset. Since I drive all day, I need the headset to call the office and clients but the radar so I don't get pulled over.
How can I connect both simultaneously? I think I'd have to use the BT headset as Call Only and the BT Radar as Media only. And I'll try that today. But will I have to re-connect each time I turn off the engine and the Radar goes out? Or will it just stay connected? Or is there another way to have two devices connected at the same time?
Of course, if there are other questions I need to ask, please feel free to post those as well.

For speed just download a GPS speedometer they are far more accurate than than anything else.
In fact if you get one that saves the data you can use it as evidence to get out of a speeding ticket.
Unless you make a habit of speeding.... tut tut.

I actually use WAZE for GPS, which also has a speedometer and is crowd sourced so that other area drivers can post accidents, traffic jams, police and other useful information. Very handy, and as a person that drives 200+ miles a day in the city, it's useful.
The iRadar detector is just good enough for certain circumstances. I found that by having the BT headset as phone only, the radar detector works the media aspect and thus I'm able to use both - as I'd figured.
When I'm on the BMW motorcycle, speeding isn't an issue, I go so fast you didn't even see me come from behind and pass you.
Hey guys,
I only use my bluetooth with my car. When I only connect to my older car that only has bluetooth phone connection, I have no problems. However, with the newer car that has text message and media link, bluetooth will keep device awake and drain battery even when the bluetooth is not connected. If I reset my bluetooth connections, it problem goes away (but comes back when I connect to the newer car again).
Anyone else have this problem? Thanks.
So. in particular, my galaxy watch disconnects when the screen shuts off, either by idle or manual. Im assuming this is a power save feature or what not controlling either the blue tooth itself, or sleeping the galaxy wearable app when screen is off. Is there a fix for this? I'm not seeming to find one in my meandering thru the device.
