[Q] Bluetooth Problems

Hi,
I have a bluetooth phone in my car, when I first connected the HTC Desire HD up, it had no problems, it paired and everything looked fine... around 10 minutes later, I noticed the bluetooth had simply disconnected from the car but was still running on the phone. I tried to reconnect it up to the car but it wouldn't, I then turned it off, and turned it back on.. it struggled to come back on, but after a few attempts it did come on and the car connected again...
About 5 minutes later the same thing happened again. At this point my phone started to really slow down, I looked in watchtower and the bluetooth was at the top of the list, soon as I turned off bluetooth the phone was responding fine again.
I have since tried connecting to the car multiple more times and have contacted HTC about it, but it seems to disconnect at random times.
Has anyone else experienced similar problems? I heard of similar problems with the original desire so wondering whether it could be something similar.

Hi Kev,
I am having similar problems with my Desire HD and Audi in car bluetooth system. I posted on another forum and found others were finding the same...
I pair my phone and within couple of minutes the phone has disconnected and won't re-connect.
Not found any definitive answer as yet, but seems BT in this phone isn't so good. Also read a post saying HTC were aware of this but an update wouldn't be available for sometime.
Hopefully someone else can shed some light!

I also noticed this the last few days with my Bury CC9056 carkit. I have my DHD since October 18th, and up till last friday it connected fine. Since then it connects to the carkit, but within a few seconds the connection is lost...

Me too. My connection to my Jabra car kit is stable once connected... but trying to get it connected in the first place is a total headache.
Never had this problem with my Desire, so why HTC should change the Bluetooth function in the HD is a mystery.

tbh i'm glad its not just me thats experiencing problems meaning it could be a software problem rather than something with my handset in particular.
I have been in touch with HTC about this, and I have just sent them the link to this thread so they can see i'm not the only one with this issue, so if anyone else has this issue it may be good to try and keep it all in here.

Mines also the audi in car system - do you find that you struggle to turn the bluetooth off and on again once it disconnects or that your phone becomes a little laggy until you turn the bluetooth off?

Yeah - I use the bluetooth widget on the home screen and once it disconnects, it will either take ages to turn off and on again, or it takes 2 presses to turn off.
I have just purchased a Plantronics 230 headset as need bluetooth for my job and it works perfectly - it's no where near the quality of the in car one though.
Also booked in my Audi as it's still under warranty - spoke to them on the phone and they said they will try and update the firmware but the Desire HD isn't on their supported phone list. Have seen a copy of this and not many phones are!!

I would of thought though, that as long as the phone does connect to the phone system in the car that it is compatible.
I have had 30mins once out of it before it disconnected and it was absolutely perfect in that time, including the phone book etc.
I do believe its something to do with the bluetooth on the phone as its a bit strange the way it struggles to turn on again once it fails.

That really hacks me off. I mean, BT is a standard. The only reason Audi can give for not supporting a phone that supports at least the same level of BT as them is that they (Audi) do not adhere to the BT standard.
Now, we all know in real life that cars and phones have problems/bugs/whatever BUT unless they can show that there is indeed a *bug* with the phone then the onus should be on Audi to support it.
Dave

Just for the record, it is not just Audi. With me it is together with the Bury carkit, where it first worked fine. (and also works with all other phones...)

I can confirm the issues with the BT. I have a parrot Mki9000 in my car and the first time when i tried to connect the DHD , the phone stopped to respond and I was forced to restart it. Since then the phone is paired with the car kit and works fine in a2dp mode for playing music, but when i try to make a call it simply not work. Yo better discribe the problem I will give an example:
The phone i properly connected and playing music, then it's ringing, but the ring sound is coming from the phone speaker not from the car. Then If i answer the call the sound comes from the phone (it shows that there is connection to the car kit). I've tried to press the speaker icon and there is a list with output devices (the phone, loudspeaker, and my car kit) I've tried to select the car kit several times , but there was no success. When I close the phone the music start to play from my car's BT system , so I think there is a problem with the handsfree function/protocol only a2dp works great , and I didn't have any issues with it. Also I've tried file transfer via BT, it works fine two.

Mitsubish Outlander carkit
I can confirm the same issue with the Mitsubish outlander carkit. It even happens that it drops the conversation. sometimes it's ok for half an hour, sometimes it disconnects after 1-2 minutes.
I also have a Jabra (bluetooth) headphone and noticed that if you pick up a call on the phone the sounds doesn't route to the headphone. If I pickup on the headphone it works fine.

I have a Pioneer head unit with BT in the car and that seems to work OK, not withstanding the fact that the HU has BT issues of its own (hardware fix needed - I'll get a new unit rather than fix it as I want one with A2DP) but once connected it works fine.
I have a Plantronics headset that seems to exhibit the same problems as your Jabra. At least if I use the phone to answer the call the sound comes through the phone. Also, if I have been using the headset the next call I make goes through the phone speaker which is a pain.
I'm wondering if HTC are routing the sound through the device that's actually *controlling* the call? So even if a headset is paired and connected to the phone, if you use the phone to make the call, as most people would, then it assumes that that's where the sound should get routed. If so, doh .....!!!!!
Just to add, if the sound does get routed to the phone you can use the 'choose speaker' option on the screen to route it to the headset but you shouldn't have to do this.
Anyone reported these issues to HTC and got a meaningful response?
Dave

I did send an email to HTC. Their wonderfull answer was about: "is your phone mentionned in the compatabilylist of the carkit, if not drop the problem there"...

I am still waiting for a response from HTC.
Mines got to a point now where I cant even make a call, it connects to the car, I go through phone book (on car) choose person to call, press call.. it tries for a couple of seconds then comes up disconnected, about 10 seconds later the phone disconnects from the car and will nto reconnect.
My phone then lags like mad until I turn bluetooth off which according to watch tower is taking up about 80% of the CPU.

any updates/solution to all these problems ?
I need it to work with MW600 before buying Desire HD

Last contact I had with HTC is they told me it had been escalted to the software team, so i'm guessing next time a software update comes out it could come about in that, but at the minute no still not fixed.

I've always thought that that's the way it is on all BT headset phones, it makes sense, if the incoming call was for my girlfriend, she can answer from the phone itself, and it automatically routes this through the phones speaker, and if it was answered from the headset, then it routes to the headset.. makes sense to me, I think it's quite good that it does that!

Do any of you have the process com.android.phone crashing when making a phone call through BT?

Ditto my mitsubishi outlander factory bt system. Seemed to work fine first time but then disconnected during first call and would not reconnect for days. Then after connecting not all functions would work ...no incoming call alert on car system, no dialling from car etc. I know the car system is fine as all functions work perfectly with my old nokia xpress music.

[Q] Bluetooth Issue when connecting with OEM Car stero

heylo everyone,
experiencing a issue which had become a pain !
i have a ford figo with OEM stero (India) which is an awesome one. i had a SE ARC before i moved to HTC One X and with Arc, once paired, there was absoultely no problem ever to pair it again, all i had to do was to switch the bluetooth on and it used to connect.
with HOX, i have a major issue, the first time, it connected flawlessly, was able to make calls, play music from phone thru bluetooth on the stero system. but then comes the problem! it doesnt work the next time, i tried to delete the pairing on both car and phone but with no joy.. i did a factory reset and it again worked once.. next time, it says its connected, but when i play music, it plays on the phone's speakers, i went to music player settings and tried to select the player as bluetooth but doesnt make any difference... i read couple of people having similar but not same problem, some have crackling issue, some are unable to connect, but this is strange, able to connect but only once.. i havent formatted the phone again for this and its a little cumbersome as all my music is on phone and i always used to use the phone to play music.
any help will be much appericiated

I have the same with an after market Sony.
Really erratic pairing. Always pair's phone but not media.
Have to randomly switch it on and off for a while til I get lucky.

It works the same as my SGS2 on my Infiniti (Nissan) nav system both for phone and media. The One X has BT 4.0 which I'm assuming is backwards compatible but it might be a challenge with some systems/devices.

Barry, Possibly yes, but i beleive new technology is always backward compatible ..
anyone had a fix ? i read about some bluetooth stack fixes, but looks like it was for a previous HTC device and not HOX..

I can fairly pin the issue down to your car audio not playing nice with Bluetooth 4.0. Yes, its backwards compatible, but, that's not always a guarantee. Get some other Bluetooth 4.0 devices to check.

have you tried restarting the phone when this happens? I happens to me now on the HOX and did happen on my old desire. If I restart the phone all connects fine and can phone and listen to music.... although the music stutters. using an aftermarket sony.

This same problem here with after market Sony MEX-BT3800U.
Before I use to have Desire HD, which was fine, now it's a nightmare.
Maybe somebody have more luck with different after market model which works perfectly with HOX ?

Mine is a Sony unit too... Possibly that one off the top of my head. It's annoying as sound quality via aux in is awful due to the low volume

Got the same problem in my Mitsubishi Outlander navigation system.Don't know why.Must be the version of the bluetoot that you'r car isn't recognizing it.You can try to do a factory reset of you'r car stereo,i did that the other day and now seems that it's working well,don't know the reason why.I think that it's the cars fault because the bluetooth headset that i use doesn't seem to have any problems working or connecting to my HTC.Even if you have open "slots" in your car to connect you'r phone,the car doesn't whipe the data of the last phones you used on it,that is why i am saying to do a factory reset.I don't know if you can do it yourself,i went with my car at the Mitsubishi Service,they conected the computer,reseted the navigation system,connected my phone and now works.

I find it ridiculous that a £150 Sony head unit has issues, wheras I have a £20 Nokia cheap bluetooth headset that works flawless, thats a good few years old.

Solved ! Bluetooth Issue when connecting with OEM Car music system
Finally this is solved for me after the 1.28.720.10 Update it now connects flawlessly and works like charm everytime anyone else who had problems tried this ?

Mine works fine with my Ford OEM headunit.

I havent had the update yet so will have to wait for that to try i guess
Mine takes agaes to pair to car BT and then doesnt connect when in range

Same problem here with a Sony head unit.
Phone profile connects flawlessly every time
Media profile seems random (though I have better luck if I leave the head unit on and switch bluetooth off and on again on the phone)
My software version is 1.28.401.9 so I guess I'll sit tight for an update and hope it cures it. I get nothing new if I try to trigger an update, so it's probably a case of waiting for HTC to pull their fingers out

Mine works great with my Sony head unit and am on 1.26.206.2 (o2) I even stream my music flawlessly phone calls work can you not take ur handset back and say its not working and exchange it for another 1

i have a mazda 3 and i have the same issue! i checked the heck out of these forums and havent seen anyone reporting the same issue i have, i was beginning to wonder if it was just me.....
has anyone else had issues with track advancing etc? not just with cars but with other devices like headphones or bt boomboxes? i wonder if the issue persists across devices.
has anyone gotten this to work with the HOX?

I also have weird experiences about the bluetooth-car connection.
On my desire, when i just get in my car, without doing anything else the phone/car would recognize each other and the music on my desire would start playing in the car instantly.
Now on the HOX, phone part always gets connected, no exceptions, media part gets sometimes connected sometimes not, if it gets connected it sometimes starts playing automatically it sometimes does not, and regardless of it plays automatically or not, i sometimes can use the controls on the steering wheel to skip songs and such, but sometimes i cannot.
Any ideas to what is causing these "sometimes"es?

Im on version 1.28.061.9 and mine doesnt connect at all. When pairing it stays on "pairing" for quite a long time and eventually it pairs but then doesnt connect
Tried a second HOX and its the same with that
Hoping that there will be a future update to fix this
This on the OEM bluetooth on a fiat Panda

Bluetooth problem when streaming in car?

None of you guys have any issues with streaming audio music/pandora/google music on your phone to the car? My problem is getting worst and I cant stand it any longer. The music would skip constantly every few seconds making it unbearable. I checked google and few people has problems with it on androidcentral, im surprised no thread for it on here?

No issues here since device came out. Have a uconnect setup in my car and stream everything from my phones BT to the vehicle's BT. My old device did that often, had an older version of BT though I think? I've yet to have issues, sure maybe 1-2 times every week a song might skip a beat but not at all on the regular. If it's a regular occuranxe it could be a bad connection. I would then delete the profile and link from scratch the vehicle and phone's BT.
Also while listening and if it gets bad. Stop the BT connection, then reconnect. Sometimes a reconnection is better than your previous and skips go away. I just turn BT off on my device, wait a few minutes, then turn it back on and let the 2 connect. Try this and the above, those 2 methods should work if not one or the other.

I get static issues if someone calls me while I am listening to bluetooth audio, and then switch back to music. Usually switching to the radio and then back to bluetooth audio resolves this. Try making sure your settings in pairing options are set to allow data transfer between the device and your car. I initially could not even connect my device until I checked off that option.

I used to have the issue with HTC One M7 and Galaxy S4 in my Renault Medianav, but no such issues with the One M8,.

I can semi- validate this issue. I have three Bluetooth devices. My headset for phone calls will get some static if my M8 is also connected to my HTC Stereoclip, but goes away as soon as I'm out of range of the Stereoclip. Because of this, and the fact my Stereoclip runs on battery and often fails to disconnect after I leave car mode, I tried switching out my Stereoclip for the RocketFish Bluetooth Music Receiver.
Now, I don't get the static, but when streaming music through the RocketFish, it skips every 20-40 seconds. I've swapped out the RocketFish twice and have had the same issue each time.
Based on queries on the Android Revolution HD thread, the developers are saying it's a base issue and needs to be fixed by HTC.
I just find it odd that the Stereoclip will steam media without skipping, but third party hardware like the RocketFish does skip. Also, my headset doesn't get the aforementioned static issues with the RocketFish.
Also worth noting I have not had both the Stereoclip and RocketFish paired to my phone at the same time.

Just wanted to second this. Mine isn't that bad, but every so often (3-5 minutes) the music skips about 0.5 seconds. Have tried stopping my navigation app, putting the phone to sleep, and unplugging the charger. Nothing works so far.
Pretty sure it is not a pairing issue since this started the first time I paired my phone to the car stereo.
Needless to say, not happening when listening with headphones or speakers.
Any insight or updates would be very helpful. Thanks.

M8 connects fine to phone and music with no issues with calls or music

I have the same problem using a Sony Bluetooth Speaker BTX300.
It's really annoying. It happens with Deezer, Spotify or internal mp3. It does not happen on voice calls.
Maybe it's something related to the Bluetooth bitrate not handled correctly by device ?

Only happens to me in stock radio over bluetooth with the mylink system in the new chevys. No problem with my Kenwood head unit in my Cherokee though

On stock Bell ROM, pre camera/EPSM update, happened every minute in my 2011 Subaru WRX as well as my Motorola Buds. I flashed InsertCoin 2.4.0 and ElementX 0.10 today... no more skipping. Not sure which it was.

I'd had this issue before on my m7 with Pandora. Are you guys using adaway? If so, disable it and try again, it should go away

Hi guys,
Resurrecting this thread. I am having skipping/stuttering issues with my phone when streaming using Spotify over bluetooth A2DP.
I've tested this on 3 different bluetooth devices (Volvo, Belkin and another bluetooth speaker).
The problem is very annoying, once the screen goes off, music would slightly pause every 20-30 seconds.
This happens when using Spotify and TuneIn Radio.. so I'm pretty sure it's not an application problem.
Anyone else having the same problem? I'm running 4.4.3 - 2.07.980.2..
Also, I'm pretty sure this only started happening after the latest update from HTC.

I'm using an app that starts playing music as soon as I connect to my cars Bluetooth. Luckily this app also provides "wifi off on connect"
Gonna give this a try. Really hope this fixes the audio drops. Hate it.

So from one day with Wifi off I can definitely tell it doesn't drop audio on Bluetooth streaming anymore.
So turn your Wifi off to fix the m8 ?

Glad it works for you as well, this has fixed the problem for me most of the time. I use the Trigger app to turn off wifi when bluetooth connects.
On another issue which I don't think is related to the above, on my Volvo at random times, I still have severe stuttering issues to the point that you almost can't tell what music is playing. I've been having this since day 1 with the M8 and not from recent fw upgrade as above. I'm not sure whether this is Spotify or the bluetooth stack tho.
Nevertheless, any of the blueooth issues were something I never experienced with Samsung Galaxy S3, Xperia Z or any other phones. HTC!!, are you listening!?!

rBlink
I have the same problems connecting to my Arcam rBlink at home with my M8. Music dropouts every 20-30 secs. Streaming from my sons M7 is flawlessly.
Stopping Wifi makes it slightly better but is no option since I want to use spotify over wifi.
Could it be a problem with a low bit rate for bluetooth audio?
Arcam gives the advice to increase it for OS X as high as 58.

I am also getting this issue as of late....
I'm using an unrooted Sprint M8 HK phone.
My problem is audio drop out (0.5 sec) constantly. Doesn't make a difference over BlueTooth or the speakers.
It appears that it is related to the phone accessing something during playback which causes the dropout.
It does it when streaming over wif or data... it even does it with audio that I have downloaded to my SD card...
I have uninstalled everything back to when I thought the issues started with no luck.
Anyone with any ideas? I see where some have had this issue and even a hard reset (wipe) didn't solve it.
This doesn't occur on my Verizon M8 which has almost the identical app's installed.

I have an international version M8, bluetooth skips randomly when streaming on car bluetooth and to my sony srs X9 speaker. It seems to happen only with continuos feeds. Mi cousin told me the problem could be that bt device is searching at all times for other devices but since there is no option to stop search i can't be sure.

Bluetooth Hell

I just bought a new car, 2017 Honda Accord Hybrid, that the cool kids refer to as HAH, anyways.....
Bluetooth output is sketchy at best.
Sometimes I get the side info like artist names and title songs.
Most of the time the sound has been playing from my phone speakers insteead of the car stereo.
Car indicates that the phone is connected but I cant get the output to function correctly.
Past ROMS and some apps have an output option but i cant seem to find any in youtube or play music.
Old 2012 Honda had no such issues.
thoughts or advice?
thanks

Maybe try to go back to stock and see what happens? What rom are you on?

Make sure you don't have any other Bluetooth devices outputting also like a smartwatch, it will interrupt your phone connection

If you go to System Settings | Bluetooth and then click the gear icon on your current Bluetooth connection, it'll give you options to select media and phone.
Did you verify both were selected? If media is not selected then music won't play on your car stereo.

So I have a 2016 Accord EX-L...The Bluetooth connection is sketchy for me as well. To get it to work I sometimes I have to toggle the Bluetooth on and off on my phone...Sometimes I have to change to a different source on the car head unit and then back to Bluetooth for it to output correctly...Sometimes it shows it is connected but only outputs sound through the phone. Additional, phone calls never worked through Bluetooth in the car. All of this was improved for me through the February security patch. I connect more often automatically like it should and my phone calls work now. However, time to time I have the same issues. I've done some research since I got the phone and it seems to be an issue on 2016 accords and now looks like 2017 have them too. I am holding out that the 7.1.2 update will resolve this problem but I have not found a solution yet.

Sounds exactly like my experience.

Bluetooth issues are now getting a lot of press on the usual Android blogs and sites. Google acknowledges that they are working on it. So there is hope.

Yep! http://www.androidpolice.com/2017/0...-random-bluetooth-disconnects-pixel-pixel-xl/

Last update screwed up bluetooth for sure. Literally bought a new SUV a couple days before I got the update. The phone worked like a dream with the 12 speaker Sony head unit before and now can be a nightmare at times.

Looks like google has a fix, but no ETA on release.
http://phandroid.com/2017/02/24/google-identifies-bluetooth-issue-pixel/

At least Google admits something is wrong and a fix is in the works. I'm glad I don't have any issues on Resurrection Remix ROM with my 2013 toyota rav4.

Has anyone had any luck on getting their pixel to consistently connect to their Honda Accord? If I restart my phone it will be fine for the day but continue with the issue after that. Sometimes if I toggle "media audio" on and off it will connect normally. Other than that I have the same old issue. Has anyone solved this through rooting?

I have to toggle media on every time I connect to my Kia pixel kind of sucks

Hey all,
So I got the OTA Oreo update a few days ago and my Bluetooth seems to be working better so far. It connects to my car consistently and fully (I can control it from the head unit and the song info displays).
Only once has it had an issue like it use to before the update where it shows it connects but plays music through the phone.
Hopefully the update solves some of the issues we have been having to deal with!

Bluetooth and Car Audio

Anyone else having issues with connecting the 7T to their car and getting audio going out of it? My OG Pixel didn't have a problem, but I have to toggle off/toggle on Bluetooth and then manually tap the car's bluetooth listing to get it to actually 'connect' the audio portion.
Rather annoying, considering I'm only in the car for a few minutes at a time, this either eats into the time entirely, or makes me sit in my car for a couple minutes before even driving to fiddle with the bluetooth settings.
Car has stock headunit, 2015 Evo X. Like I said, original Pixel XL had no issues, but this is annoying. I've tried changing bluetooth versions to no avail. I can see it connecting and dropping the bluetooth connection fairly frequently while staring at it and trying to 'get it going'. But once it connects, it stays there.
My bluetooth headphones (Some knock off cheap Chinese ones for $20) don't seem to have an issue.

My connection to my aftermarket stereo is fine. Just seems a little quieter than my last phone. Connecting is kind of slow too when I start my car but it is automatic.

I don't have any issues with connecting to all 3 cars (2014 Honda Accord, 2009 Pontiac G8 Gt and a 2018 Honda Fit) but I do agree that the volume seems a little lower than my previous phone (Galaxy S8).

Hmm. Weird. Is there anyway I can check for logs to find out what exactly is happening? I haven't rooted, just don't know if it's something I can naturally pull from Android as a whole.

I had the same issue, but when I made the phone discoverable and initiated bt from the car stereo it seemed to work.
I also set a custom pin , not the default 0000

My bluetooth is quiet, but its also static-y. I never had any issues with my G6 and now I get static clipping every 10 or so seconds. Its unbearable.

I'm not really having an issue pairing it, but it's just connecting after pairing is the problem.
I have changed the default pin. I can see it popping up and down the car stereo a few times in the bluetooth settings before it just gives up.
As for the other issues, I'm not having a problem at all with audio volume, nor popping/static when it finally does connect.

My volume is super low when connected to Android Auto and streaming music. Have to turn the radio up to max. However, I'm assuming that's an AA issue or Android issue, as it seems many others are having the same problem with different phones. Been thinking of adding an aftermarket amp to the car. Maybe I should pull the trigger. Lol

Be careful that a bugfix doesn't come and blow your eardrums out, lol.

My OnePlus 7t connects fine and phone works for calls on 2014 cts. The sound comes out of phone can change song on head unit but I can't get audio to play through car. Anyone else get this?

Yeah music stutters with car player... Only calls work. Music works on headphones etc. I couldn't find solution, did network reset, cleared cache. Nothing works.

Seriously!
I've wasted at least two hours already trying all the recommended steps: from flicking icons on and off to a full phone reset.
Still no connection to my Suzuki S-cross car. Multiple previous phones have connected effortlessly.
Even the $50 temporary five year old borrowed phone could handle it.
Anyone got any other suggestions? Yes, tried the AVRCP setting change from 1.4 to 1.6. That didn't work either...
Barebones system reset from scratch running O2 OS 10.0.6HD65AA
Any suggestions greatly appreciated.
I need to be able to talk and drive!

Reset the car radio and clear all pairing data if you can. Then try again.

Thanks for the suggestion.
Tried that.
Tried one other car - no problems.
Tried a tablet and a very old phone with the car and suprise - the car's bluetooth seems to be the problem.
I will try and find out if I can fix the car!
UPDATE: Morale of the story - read the car manual very very carefully and go though each tedious step = SUCCESS

Yep most have lots of tedious steps that are different model to model and if not followed exactly will cause this problem on occasion..

In my case music starts to be scrambled after 10 minutes or so of listening. When I take the phone (so the watch pops up) or turn on the screen it immediately works fine again, but when being put aside and the screen turns off, the issue starts again ..
Also in the early days of my previous 5t I had the same issues but some fix was delivered together with oxygen os update. And now the same story again

I have a different issue with Bluetooth:
- OP7T connects to car Bluetooth fine
- I can make/answer calls
- Bluetooth media works fine
The problem is with Google Assistant & car audio:
- it was working as intended until the latest update - 10.0.15 - I was pressing the button on the steering wheel the google assistant was answering questions through the car bluetooth, no need to switch to bluetooth media.
- after the latest update, when I press the button on the steering wheel, Google assistant pops on the phone , starts to answer question, but cuts off after 5 seconds. the command still goes through and Assistant still runs, but does not come up on the car audio.
- it looks like the Assistant is not connecting to the car as a hands free, but as to a bluetooth handsets.
Anyone experiencing this?
