[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.

I trust that all of you bother to report this to HTC, at least once per instance ?

no sound after bluetooth unpairing

Hi, I have been searching and can't seem to find anything on this. My wife's and my epics pair, and work, great with with our car stereos (clarion). but, when we get out of the car, and the phone unpairs, we have no more system sounds. we miss calls and texts because we never hear them. the sounds now only come out the ear piece. Only a reset corrects it and then we hear sounds from specker again. Of coarse until we get in the car, and it all starts over again.
any ideas? I'm stumped.
thanks!

have you tried turning bluetooth off entirely when u leave the car?
also are you using any applications to send media with bluetooth such as BTmono?

I have the same problem -- as does my wife. I'm using a Motorola BT in the car, but it seems to be a problem with any BT connection as she primarily connects to our BT phone connection in the house. I saw this problem mentioned in a couple other threads, but no real solutions other than things like turning off BT on the phone before disconnecting, etc. Frankly, that's a hassle and I never remember to do it. I was hoping the latest version of Syndicate ROM might fix it, but just had it happen again this morning. So, I can confirm it's a problem on both Froyo stock and Syndicate ROMS. At least it seems like rebooting is a bit faster on Syndicate, so that's my solution for now as soon as I realize sounds aren't coming through. Just gotta remember to check before I miss a call!

thanks for the replies. I am not using anything that starts to stream to the car stereo. Music player use to, but I removed it. I did notice today that the specker sound loss only happens if i make/receive a call. Today I drove to store and while in store away from car sound was fine. got back to car, called wife, and then when I was at home sound was gone. I will try to toggle off BT before phone is unpaired. what a pain.

Wouldn't ya know I found a thread about this after I post this.

This post has worked for me: thanks mattallica76. I had to be in car paired to do this.

This problem is a bug that exists while using Bluetooth on a device for both ad2p and phone calls. The only workaround (until Sammy or one of our great devs comes up with a fix) is to use the BT device for one or the other. This will prevent the audio from being routed to the phones earpiece after BT disconnects. To do this, go into the phones BT settings. Then long press the device that you are having trouble with. Next uncheck "Media Audio" or "Phone Audio", depending on which purpose you want for the device.

CM11 Bluetooth Problems

Curious if anyone would have any insight...
I hadn't used bluetooth too much, but I occasionally used it with my Pioneer car stereo. I know that CM10.1 had some issues with bluetooth, so I figured that was the reason it worked intermittently. I purchased a different car stereo, and couldn't get my Epic to pair with it. Basically it would see the car stereo, start to pair, let me enter the passkey, then bluetooth would turn off, then back on and it will keep doing this. So...I wiped everything and installed CM11, which I thought (and heard) would have much better bluetooth. But I'm having the same exact problem. At first it was saying that my passkey was wrong as it would turn off, or I might get a bluetooth process force closing, but it always ends up turning bluetooth off, then back on again as it tries to pair. I also tried pairing it with a bluetooth HMDX speaker, and the same exact thing happens. Just wondering if anyone might have a few tips on what to check out instead of going back to stock.

I too have been having a very similar problem with with my plantronics headset, and Panasonic Bluetooth cordless phone. My Nexus 4 will continue to disconnect and reconnect, have tried to pairing the devices again with no luck. tried a few nightlies of late with no luck yet.

I have a 2014 Mazda CX-5 and a Samsung S3 and I'm having the same issue.
The odds part is that I have no problem connecting and staying connected to my pebble smart watch.

Bluetooth pairing problems

Hello, I am getting weird problem when using bluetooth devices with my HTC 10 (stock rom)
I bought a bluetooth device with aux-in for my car radio.. That way I only enable BT on my phone and devices connect without problems.
But I also have a small Bluetooth speaker I use when I renovate the apartment (JBL GO).
The problem is when I paired car bluetooth device so it can connect automatically and after that also connected bluetooth speaker this one does not want to connect. If I unpair car bluetooth device, the speaker connect normally.. also if speaker connect and I come down to my car and try to pair to car bluetooth device, it doesnt want to connect/pair... Again if I remove BT speaker from paired devices, car bluetooth device connect normally...
Why is that, anyone knows a solution? Why can I have only one BT device paired with my phone?
Thank you for answers

i have this problem too.

Had this problem myself.
Updated to the latest firmware, rom and kernel.
Currently using cleanslate.
Turn on the BT device, make sure no other BT devices are in the near radius which may confuse it, no wireless devices (I know hard in this day and age)
Turn on BT on your phone, hold it up clearly (not laying down) close all apps, and open the Bluetooth menu.
Click the Bluetooth device to make sure it's ready to pair. Then scan on the phone.
Should start picking it up.
Repeating this and turning the BT device on and off periodically, allowing for several attempts at a time before switching off..
Even really it'll work, perhaps a different rom or kernel combination may help..
I have had this problem, once connected it'll always work and work well. It's odd

Same issue somewhat..I really want to keep this device...i dooooont want to go back to the s7. But on the S7, i could have my Gear S2, Sync and LG Tone all paired at the same time...If i got a call they would all ring and i could answer on whatever device...now if i have the LG on, sync wont find the device. or the phone wont allow for sync to use the Phone, because the S2 is using that feature...what gives? just me?

Do you have another device to try it with? i have had a similar problem, but its just my terrible bluetooth rockford deck causing me grief, and an ebay pill. But it did it with a lg g3 and xperia phone as well. so i chalked it to that

Seems like HTC only allows one bluetooth profile at a time. Like it will only allow one device to use the phone profile or one device use the media profile.
I have to turn off my tone for Sync to connect. Sucks.

I've had this problem since purchasing the HTC 10 about a month ago. My Bluetooth earphones work without issue, but I've been unable to connect to my car or portable speakers (pairs but never connects).
After reading this thread, I unpaired the earphones, cleared all devices, and I was finally able to connect to my portable speaker. So glad I found this topic.
Still, I'm hoping for a fix. I don't want to bother with pairing and unpairing just to connect to a different Bluetooth device.

Similar problem
Hello !
I am having a similar issue!
I have been trying to register and pair my phone with my car's Bluetooth.
Every time I try to pair with my car an error message pops up saying "couldn't pair with Hands Free System because of an incorrect PIN or passkey" except it never even prompted me to enter the passkey...
Things I have already tried:
Resetting network settings
rebooting phone
Factory reset phone
Also , I do not have any other devices paired with my phone.
Any suggestions??

Bluetooth no audio in Bmw 323i 2010

guys
pixel 3 xl is not playing well with my BMW 323i 2010 bluetooth call system.
When i get a call the ringtone comes through the car speakers. Then when i accept the call there is no more audio through the car audio system.
i tried unpair and reparing and same issue.
my original pixel xl works fine.
any idea? any1 having similar issue?

I have a 2013 328i, and this is the first phone I've had since the Nexus 6 that actually works well with it for music. I always had problems with the Bluetooth freezing.
Sent from my Pixel 3 XL using Tapatalk

sometimes telling the assistant to play music will get it to play nice if it is still paired just not sending audio. but for phone calls, thats weird

Did some troubleshooting today.
So after connecting the call if I manually select phone on the pixel3 and then switch to car audio Bluetooth then it starts working.
But it doesnt start automatically when the call connects.
I will log it with Google and hope for a fix.
Thanks guys.

Try resetting the cache for the Bluetooth app in the app manager in settings (You have to tun on system apps to see it)

2013 BMW 328i, never had an issue with any other phone, seems at random call audio will stop working over Bluetooth in the car and the only remedy is to reboot the phone. Have tried everything with no solution.

yep, my issue still not fixed and making me crazy.
1 thing i am gonna try today is that disconnecting p3xl from my samsung gear s3 and see how it works while only connected to bmw's audio. if that does not work then i will send this phone back.
it is insane how many software issue this phone has.

Argh, same thing with my 2011 128i. NEVER had a single problem with my Pixel 1 XL, got the 3 XL a few days ago. Today I need to make a call in the car, pair the phone and... no audio. In fact I think it was still playing music, even though it showed "Connected". I have the "Professional" audio system; ie: the simple one. Not with the big display etc, iDrive I think it is.
Could you let me know the bug ID you logged and I'll star it and participate in it with logs etc as they request them? I don't make a lot of calls in the car but I often drive into work listening to conference calls so this is seriously annoying.
My two bluetooth headsets work fine, so it doesn't appear to be a overall issue with bluetooth headset audio etc. I might try it in my wifes car just to see if it works there, for more datapoints too.
Very, very odd... I read a suggestion to boot into safe mode and connect the phone to the car and that worked, everything is fine now. What's stranger, to me anyway, is that it continues to work fine! But as odd as it sounds, this is something to try.
