Bluetooth woes - Nexus 4 Q&A, Help & Troubleshooting

I've had issues with Bluetooth since I bought this phone, over a number of different ROMs and kernels. Basically it refuses to connect to my car at random. Sometime it connects fine, sometimes I have to power cycle it to get it to connect. I recently started playing with Tasker and noticed something strange. Tasker is actually registering a Bluetooth connect and immediate disconnect every 11 seconds. The Bluetooth icon never changes to blue, however.
Does this sound familiar to anyone? Is there a log I can check that will give me more details on why it's not staying connected for more than a split second?

Have you tried other bluetooth devices to your phone other than your car? If yes, then it's the phone, if not, then it's the car. If it is the car, is there a way to "update" the bluetooth drivers on it? Is it a VW or BMW?

I actually don't have any other bluetooth devices to test it with. My Galaxy Nexus connects just fine to it though. It's a Logitech Liquid Aux device.

bluetooth switches itself off!!!

Using the Touch HD with a builtin bluetooth car kit. Everything works fine, the phone's contact list displays on the screen of the car. The pairing went fine. Call history works. Happy me. But occasionally i notice after making a call via the car (after hangup) the connection disappears and i check the phone. Bluetooth is switched off!!! How can this be? Are there any settings i have missed?
Any other users experience this?
same here with my bt handsfree
what if you connect it to powersupply ?
with power : working
without power : after some minutes off
sometimes I can not access the contactlist, stop the car, remove the key, start again and it works
There is something wrong with BT + car
I've had my HD a couple of days and use it with the built in BT in my Audi. The car displayed "telephone is not connected" and when I checked the phone, no BT icon. I've had problems in the past with other makes not working very well like this and was thinking it was going to be the same here... As I was getting annoyed a call came in, rang for about half a ring on the phone then it reconnected to the car and continued ringing there, answered the call just fine.
Since then it's done the same thing twice, I'd prefer it didn't but it hasn't actually caused a problem yet.
BT shuts off by itself.
I seem to be having the same problem in my Audi Q7. It does not make a difference weather to be connected to a power supply or not.
Im having the same issue here, in my A4 Cab with integrated UHV 0420
Strange thing is, it doesnt disconnect from my works Parrott kit.
It does turn off the Bluetooth on the phone, strange. It didnt happen for the first week though.
Any ideas?
Bloke
same here. having problems with my Land Rover LR2. first week, there were no problems. now, the phone doesn't automatically connect when i start the car, i have t manually connect it by pressing the phone button on my dashboard. it then connects with no problem. however, when i try to place a call, it automatically disconnects the bluetooth.
not sure if this is a problem with the htc or my car; i have to try another phone with the car first.
Same happens in my Lamboughini and also my Mercedes- Benz E Class.
Looks like I'll just have to stick with my roller from now on!!!!
I see I'm not the only one with this problem. Soooo...... anyone got a fix?
Please, at least have you checked for a few seconds after the disconnect to see what happened ??
Well, I have a BMW S1 with in-car bluetooth. I previously owned an S200, SE K800i and a Touch Pro and never got any problems with those phones.
With HD Touch I also have the same problems like you people, but 2 or 3 seconds later the BMW regain the connection with my HD.
So, for me this is no big deal. If this only happens to me, then I'm the first to apologize my introduction on this post, if not... lol
Im sure its not related, but I installed the hotfix for the TF3d earlier and I didnt have any disconnects on the way home....... ????? Go HTC.....
Bloke
yesterday i installed the hotfix from htc, but today i lost bluetooth connection again in the car. The bluetooth in the car keeps functioning, but the bluetooth on the HD has deactivated itself! With my previous sony ericsson phone (also bluetoot 2.0) i didn't have this problem. So i think it's related to the bluetoothsoftware on the HD.

Have a look at this thread - also bluetooth problems with pairing issues - looks like BT maybe bugged
http://forum.xda-developers.com/showthread.php?t=442987&highlight=bluetooth+problems
Hello,
I have the same problem. I can not really use bluetooth in my car, because the Touch HD ends the connection after a few minutes (most times after less than five minutes).
Without a connection to the car, bluetooth will not be ended by the Touch HD, so it seems to be a problem of a connection to a bluetooth headset or a problem of a connection only to a car bluetooth "headset".
Regards
Thomas
Does this only apply to original built-in bluetooth kits and not after-market kits?
My BT-radio does not have problems with the Touch HD, but it is an after-market radio.
Same problem here. My connections drops also. I drive an Opel Zafira with builtin bluetooth carkit. Bluetooth is turned off after a while.
I've noticed when i start the car a connection is made and a few seconds later bluetooth is turned off and immediatly turned on again. After it's turned on, the connection is stable for a while. A few moments later it turns off again. Then i have turn the bluetooth connection manually.
Today i had a phone confercation for a half hour. The connection stayed stable. When i hang up the phone, the connection dropped .
Can the synchronisation of the phonebook be the problem? I had this problem with my p3600. After installing Jetware, the problem was solved. I've installed Jetware on my HD, but with no luck .
Is there a way to log the bluetooth communication. May be it tell us more
Indeed the HD bluetooth seems to be poor, I also experienced bluetooth switching off by it self when trying to pair with my Motorola S9 headphones, I have the hotfix installed, before I didn't notice this bluetooth behavior.
Also when exiting Opera the phone hangs, not always but sometimes
Anyone solved the problem yet
I send a email to HTC support. Hopefully they can help. If they answer......word goes arround that htc support sucks
still don't have a solution.........

Htc Hero Bluetooth Car Kit

Hello
I am trying to get my Hero to connect with my Lexus RX400h's bluetooth car-kit. I can pair the Hero with the car but it will not reconnect. Is there a way to authorize the Hero to alway reconnect without having to re-pair?
Any help would be great.
Thanks
Jon
It should remember it. I've never had a problem with my own bluetooth kit.
I get paired but not connected with my thb bury kit there are lots of posts on here about bluetoth issues 5 series bmws also have problems, htc support say they are waiting for an update from google
I'll add the Range Rover Sport to the list of cars with bluetooth issues.
I can connect OK, but as soon as the phone is connected it disables the phone keypad on the car dashboard so I can't use it to access voicemail and other menus.
Worked fine with my Diamond and Touch HD
Toyota TNS 510 carkit wont work either. It pairs ok, it even pairs the A2DP system. When pairing is finished a little message appears on the phone saying there was a problem with the bluetooth handfree thingy.

What model year is your RRS ? My MY08 D3 works fine with the Hero... contact list navigation is far better than my 'old' Nokia N85. If your RRS is pre MY2008 there is an ECU update for the Bluetooth PTI I believe.
I'll add a Jaguar XF to the list. Hero will pair ok, then it will disconnect. it will disconnect a few times before it settles down. Whenever it tries to auto-connect, it will disconnect 2 or three times before it stays connected. sometimes it wont connect at all, a quick disable, then re-enable of bluetooh on the hero then gets it to connect again.
Didnt have any problems with any BlackBerry's, Touch Diamond, Nokia e52. Looks like we're waiting on Google for a fix. I wonder if their continual beta policy applies to updates as well as full blown applications?
Peugeot 407 SW ('07)- Pairing okay, connects okay too. On phone call the radio is muted, call picked up (on incoming), but the sound keeps coming through ear piece for 4-5 sec and then it eventually switches to speakers.
HTC cust support not very supportive... pointing me to go to the car manufacturer for support... :s
The Hero and/or Android does not support the bluetooth stack's remote Sim Access Profile (rSAP/SAP) required by many car kits (VAG, Lexus etc.). This might be the issue here.
http://en.wikipedia.org/wiki/Bluetooth_profile#SIM_Access_Profile_.28SAP.2C_SIM.29
Let your car do the pairing
Turn bluetooth on your phone and let your car discover and pair with the phone. Your carkit will suggest the passcode enter it in you phone and not the other way arround. That might work, It did for my Porshe.
How do you transfer bluetooth contacts??
Hi. I have my bluetooth car kit working fine, it is with a pioneer head unit. At first i would have to manually connect it, as the phone can only be made visible fo 120 seconds. Hoever after doing this 5 or 6 times, it then automatically conected every time. Just keep trying and see if it eventually does it.
Also.... How do you transfer your contacts lists to the bluetooth device?? I cannot find anyway!! please help!!
No Go on the Mazda 3
just bought a 2010 Mazda 3 sport and the bluetooth does not work with hero.
it pairs with the phone and then occasionally connects. however when you dial a number by voice or keypad the system in the car locks up completely for about 4 mins. tried other phones and works perfect.
Strange thing is it did work once for a day but then went all haywire after that.
would rooting the phone and installing a different rom open up the bluetooth any more so it can communicate better.
Dont want to get rid of the phone but unless i can find a remedy im gonna have to get a different phone.
I have Lexus ES350 2007, It's paired and auto connect with no issue! I have a tiny issue with incoming call in navi screen it display "not supported" instead of caller name!
Also it ringing in my Hero for 4 seconds then it ringing in my car?!
Thanks
Sorted
Well ive sorted th bluetooth problem.
once paired as long as i dont turn off bluetooth on the phone then it connects / reconnects just fine. if i do turn bluetooth profile off then when pairing i need to make phone visible before i get in the car and it picks it up again.
sorted.
2010 Mazda 3 and HTC Hero Bluetooth
Have the exact same problem as Wingy999 and if I leave the bluetooth switched on on the phone I have no problem.
But if I do switch it off/restart the phone, even if I make the phone visible when I get in the car, it does not connect and I have to delete and repair the phone to the car.
Can you help wingy999?
Yes/No
Well its a case of Yes it is and No it isnt.
Sometimes, for a few days i have no problems with phone. Then for no reason it decides to connect (picture of the phone on dash) but it cant communicate with the car. So when you dial it just hangs the system.
Got sick of pairing it to be honest so have left it for now. i wondering if rooting the phone might be a way forward.
yeah, no clue if rooting will help, but im def waiting for it to be possible. lots of cool things that can be done.
the bluetooth problem is to do with the android bluetooth api itself from what i understand. google haven't figured it out entirely yet and so only released it with basic functionality. even once modders are able to get inside the cdma hero, i dont think they can get at the low level bluetooth functionality and make changes. I could be wrong, but if it were the case, we'd see things like obex object transfer available on the GSM Hero's already.
I also have the same problem with my 2010 Mazda 3 and my sprint HTC hero.
I am probably going to have to return the phone. I was hoping for an update or a fix.
It is critical that the bluetooth feature works.
Another annoyance is that I cannot turn the bluetooth streaming audio. Even though the car and phone both have this feature, I do not want it on. I want to be able to turn on bluetooth for phone but not bluetooth streaming audio.
The HTC touch pro 2 (windows mobile) could turn each of the 2 bluetooth services off independently (and worked for both), the HTC Hero does not allow this (and doesn't work with the car anyway).
Huge thumbs down for an otherwise great phone.
My issue is with a Jabra SP700 Bluetooth speakerphone. My phone is paired, is detected and the phone even says 'Bluetooth Headset Connected'.
However, sound is not routed to the speakerphone, it just comes out of the phone speaker...
FYI I'm running MCR 2.8.
BMW 1 series 08 and HERO
Before I buy an HTC Hero does anyone know if it will work with my BMW 1 series

[Q] Bluetooth Devices Disappear?

I have been patrolling the forums trying to find a solution (or at least a thread similar) to my problem. I made the move from the G1 to the Vibrant in Aug. I was spoiled by it so it feels. I've grown quite custom to my Bluetooth devices being remembered by my phone, and not having re-sync them everytime i want to use them. I'm wondering if there is a fix for this, or is this apart of the Vibrant framework and i just have to get over it? Has anyone else been experiancing this?

Speak now or forever hold your piece. This is a huge nerd farm and im sure we can all put our heads together.
Are you talking about pairing or connecting the device? I only have one bluetooth device with my phone, and the phone has no problem staying paired to it. I do have to reconnect it when I turn on bluetooth, but that's all.
To clarify:
I turn on bluetooth.
My headset is shown on the devices list.
I press it once and it connects.
Device is ready to use.
Once, the device didn't show in the list while BT was off, but when I enabled BT the device was displayed.

What i mean is, I normally have more than one BT device connected. More specifically my BT headset, and my car BT stereo. I used to be able to have both devices remembered in my device list. But now my BT Headset is the only remembered device (and sometimes, it too will disappear. Now i constantly have to re-sync my stereo. However when a re-sync is needed, i don't have to pair the devices.
On my G1, this was not an issue. So any ideas?
I have my laptop, headset, and stereo headphones paired to my phone. Haven't had any problems, they all remember fine. However, I sometimes have to disable and re-enable Bluetooth because I have a custom name for my device, and sometimes when the phone boots it forgets that it has that name and goes back to calling itself SGH-T959. I don't know if this is related... just throwing it out there.

This does help a little. Perhaps because I am still stock, I am having this issue. What ROM are you using?

I've had the problem on stock JFD, JI6, and on Bionix with JAC Voodoo kernel.
I'm having the same problem with my car's BT system. I thought it was my car till I read ur post. What happens with me, is that the car (which should connect automatically) will say that there isn't a phone available. I will then open Bluetooth settings (on my phone) and see that there are no devices listed. After cycling the BT off then on, my car will show up again, and will connect......strange

Exactly my issue. So seeing how i am not alone in the issue, does anyone know a fix or how to resolve issue? It's not a BIG problem, bnut it is annoying to have to re-sync everytime i get in my car, (or send files from my iMac to my phone).
+1 for the vibrant forgetting my bluetooth devices. I'll open my headset and I hear it say, "Ready to Pair". It's not a big deal, really-- all I have to do is turn bluetooth on, then turn it back off and all my devices repopulate. But it is an annoyance.

[Q] Problem with dual Bluetooth audio devices

I have a Jabra Freeway in my car and Plantronics M165 in my ear. My iPhone would work with both devices at the same time. Even with the M165 on, the iPhone would connect to the Freeway when I got in the car. When the phone rang, it rang both devices and I could answer either one.
Now I’ve got the Note 3 and it seems that it will only connect to one or the other. Both devices work fine. Just not at the same time. If I get in the car with the M165 on, the Freeway just says “disconnected” repeatedly until I turn the M165 off.
I presume this is a limitation of the Note 3 bluetooth stack but just thought I would check to be sure. I read on another forum where someone said it should work with both devices but that was all that was said. Anybody actually do this with the Note 3?
From what I have found you can have 2 Bluetooth devices connected at the same time, but not performing the same function. For example, you can have your headset bluetooth set as the active bluetooth for phone functions and your car bluetooth set as the active bluetooth for media functions. If you long press each Bluetooth device within the Bluetooth settings menu on your phone, you can choose how your phone connects via bluetooth to each device.
and that is, from what I understand, the Bluetooth limitations for Android.

That's what I figured. I'll keep my fingers crossed that KitKat updates will remedy this. In the meantime I guess it's a small thing to give up in exchange for the gains.

Bluetooth to car stereo, no auto connect

I had the Note 3 and it interfaced very well with my 2013 Subaru Impreza stereo. The Note 4, however, will initially connect but after turning the stereo off, then back on, it will not auto reconnect. The same behavior happens when the car is turned off and on.
I must tap the stereo in the BT app to get it to reconnect and sometimes I have to turn on the phone "visibility" to get the connection to happen.
So, that means no BT phone unless I'm already listening to a BT source.
I think it is related to the newer BT stack and its low power modes.
Anyone else seen this BT behavior?
Yes, I am seeing similar behavior. My Bluetooth tends to disconnect at times, seemingly at random as well.
Also very frustrating is the fact that I can not just enter my car and have the Bluetooth auto connect. I have to open the bluetooth page and select my car from the list of devices manually. This seems primative. If there is a way to change this can someone please post it?
I've started using Tasker and it has saved my bacon. Works like a charm. I've even used it to automate turning on Slacker when I get in the car.... So, a work around...
I have no problem whatsoever while connecting to my Dodge Charger 2014 ..every time i get in the car the Note 4 auto connects... i have the viisbility timeout set to Never..
