Connecting 2 phone with bluetooth - Android Q&A, Help & Troubleshooting

The idea is like trackr bravo/tile.
You pair your phone with trackr bravo or tile, and when it's out of range, we can make the phone play a sound.
I would like to do that with just 2 phones, but apparently, I can only pair it without it connecting constantly unless it's doing something like file transfer. Once the activity (like file transfer) ended, the phone will disconnected (while still being paired).
Any app that can make the phone connect constantly?
Thanks.

BT GPS feature on a BT HEADSET.

i have a BT-Q818 and one cool feature it has is that it goes on stand by mode once there is no connection. this is the case when i step out of the car. and whenever i start driving again, i seem to have had no pairing issue.
question is, is this FEATURE available on any BLUETOOTH HEADSET? reason being is that i only use my BT HEADSET when i drive and im getting tired with my current HS810 where its a hit and miss. sometimes it would pair and sometimes it would not.
thanks for any input guys.
Upon disconnection, the Nokia HS12-w displays "disconnected". Pressing the play button for a couple of seconds causes it to reconnect (I suspect to the last device it was connected with, but am not sure about that - I can test it if you like).
But even if you switch it off and back on, there is no need to pair again: it just starts searching for paired devices and connects with one of them (alas, no choice regarding what device it connects with, but it does seem to prefer Nokia devices over HTC ones).
The first connection it makes is as a headset (only calls are routed throught it, other sounds still come from the HTC). After pressing another button it also connect as an A2DP device and all sounds from the HTC are routed to it.

[Q] Bluetooth auto connect

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

Mate 10 Pro - Bluetooth woes

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)!

Android 6.0 / Bluetooth Share has stopped / Issue with A2DP profile (?)

Hi all,
first post, this issue starts to drive me mad :crying:
My device is a Lenovo C2 (K10a40), not rooted (If BTW anyone knows how to root this device: You're welcome )
I have Bluetooth connections to many devices. My car and my wife's car (Phone Audio and Media Audio) , Raspberry pi (Media Audio, to stream from device to rasppi), a Philips TV with a "built in" Bluetooth speaker, to stream from device to TV, and my Linux PC (Phone Audio and Media Audio), to dial etc. from my pc when sitting at my desk.
ALL of these connections are working fine, except one, to one car:
- When paired for the first time, all worked fine for a long while, days/weeks/months
- No idea why, once and suddenly when re-connecting the device and the car, after some seconds, AOSP standard media app "Music" starts, and again after some seconds, a popup says "Bluetooth Share has been terminated" (or very similar, translated from German msg).
- Car says on radio screen "A2DP has been terminated"
- Both car and device tries infinite to reconnect, same issue
Tried the usual stuff:
- Clearing cache: no change
- Resetting network (and Bluetooth) settings: no change (after painfully adding all WLAN and Bluetooth connections again :crying
- Rebooting both car's radio and android device. no change
I didn't try and really, really, really don't want to try a factory reset, would take me ages to reinstall and reconfigure everything, as I'm not sure if simply restoring a backup after resetting the device will re-introduce the error anyway. I don't want to test it :silly:
What sometimes, whyever only sometimes helps (for a short while, sometimes days) is to drop phone from car's paired devices and vice versa, and re-pair after that.
My question is, could be a deep technical answer if necessary: What on earth triggers the start of the "Music" app, after (re-)connecting both device and car? The Bluetooth crash *** ONLY *** happens, if "Music" app starts. Before first crash "Music" app has NEVER been started. Now, when successfully paired after dropping connections as described, "Music" app does also not start at first. But as soon as "Music" app was used to stream media to car, it's going to start automatically after reconnect. Although if for instance media playback has been terminated before disconnecting, e.g. for listening to radio. For a while then reconnect with automatic start of "Music" app works, and after a while the crashes appear again.
On the other hand, if "Music" app is started automatically after a re-pairing, after dropping connections before, at the first Bluetooth connect, the crash is ALWAYS a result.
I also found out, that if I'm DISABLE A2DP "Media Audio" profile in the connection settings of the android device, connection is stable and "Phone Audio", including adressbooks sychning etc. works fine and stable. But unfortunately not "enough", I need A2DP for navigation audio.
Any hints how to get rid of these "Music" autostarts would be great!

Bixby Routine with car bluetooth not always activating?

I made a bixby routine as follows: when my phone connects to my car bluetooth (VW Passat), it should do several things. But the problem is that the routine almost never starts working by itself? It only works after I manually turn off bluetooth and turn it back on after im already connected to my car. Anyone else have this problem? With tasker there's no such problem when connecting to my car bluetooth, but i'd like to use bixby routines instead of tasker...
Even though I have another routine which does several things after connecting to my BudsLive, and that one always works by itself without problems.
When you get in the car do you activate "media" on car, or just get in and let the phone connect to car? I have noticed on a lot of devices if you don't "fully" connect to media on car, such as playing streaming music many phones don't see the connection unless Media connected (you can pause music). I'll get phone calls fine, but no messages or Maps audio at all unless Media connected. As I said, same with all my older phones, started I think around Android 9. Think part is car manufacturers don't want to support phone options anymore, they want you to use Android Auto or Car Play and leave the software to Google and Apple.

The thing is, my car bluetooth doesnt want to activate "media" lol. It only connects for phone calls. When i try to activate media the button always returns back to off. Seems to be a samsung/volkswagen problem since i see alot of posts with the same problem when googling
I had Bixby Routines set up on my S21 to do some things automatically when connected with a car Bluetooth kit. Everything was working fine until the last update of One UI 4.0. After the update, nothing happens when I connect to the Bluetooth kit in the car. I deleted the Bixby routine, reset the app data, deleted the Bluetooth partnership, and reconnected to the car's Bluetooth kit - nothing helped.
When I create Bixby routines using regular Bluetooth headphones, everything works fine. The problem only occurs with the car's Bluetooth kit. While searching the Internet, I found out that there was a similar problem with Bixby procedures before. Back then, Bixby routines would not work if the bluetooth device did not have an audio profile. My BT car kit does not have such a profile, only a hands-free profile is available. Has the old malfunction returned?
