Very poor bluetooth connection

Hi guys,
i recently received my iTech R35 A2DP Bluetooth Headset for my Touch HD which is identical to HTC BH S100 since its only rebranded.
Pairing, controls and everything works fine, but when playing music the connection constantly gets lost for short terms regardless of the distance between the phone and the Headset.
The weird thing about it is, that the headset works perfectly with my friends HD. He even could go away like 10m without any kind of interruption.
I already tried some different settings with HD Tweak but no improvement.
Besides I noticed that overall bluetooth performance with my phone, as it once took about 30 minutes to send a 50MB file, isn't that good.
Thanks for any help!
Update:
I tested the Headset today with two other phones (SE W950i and some Nokia). It worked perfectly so I figure something has to be wrong with my phone. I'll perform a hard reset on the weekend and see if it changes anything. Otherwise I'll have to contact the customer service.
Has anybody here experience with german support. If I had to send the phone in, how does it usually take til u get your phone back?

Well, I just performed the hard reset and it solved the issue. Very strange since I hadn't installed that much programs.

Well, the problem returned and I now figured it out in detail.
There's no correlation with the programs installed.
Once the Bluetooth headset is in the Bluetooth-Device-List as it was connected before the constant lags are there.
If I delete it and re-pair the headset the lags are gone for this one time until the headset got disconnected. Even if I get out of range and return in reach connection is crappy from then on.
Didn't anybody recognize such a strange behaviour too?

I have a similar issue with my Sony Ericsson HBH-IS800 phones.
I thought I'd solved it by re-pairing with the handset, and initially that pairing seemed to last for a while, but now it seems I have to re-pair at least once a day to avoid the stuttering (it's really bad, isn't it?)
Frankly, I'm getting pretty disenchanted with my HD. Every time I discover a tweak which sorts an issue, another issue raises its head. I've lost count of the many hours I've spent trrying to get it to work as it ought to.
Wishing I'd got an iPhone. Okay it's not as good on paper, but at least everything works....

I have to agree the bluetooth is dodgy for me at the best of times in trying to connect to any computer.
Surprisingly, Ive had a good file transfer between my HD and MaxOSX, I can't say the same for Windows XP or Vista where on both accounts it has failed to connect via bluetooth to perform an active sync.

Thanks for your information. At least I'm not the only one with this issue.
Meanwhile I tested this behaviour with my buddies HD and it's the same pattern with his one.
I contacted german support today and will report after their answer.

i've been having the exact same problems with my hd. i would be able to pair it with my landrover, but then the connection would be lost. (there's another thread on this somewhere).
anyway, i tried installing BTRestore and BTRestart along with Mortscript and a custom script to help keep the bluetooth active. however, my problem was not that the bluetooth was turning off, but that the connection would not stay active.
so i installed a custom rom, Dutty's version 1.7, and also installed jetware bluetooth program (www.jetwaremobile.com); so far so good (*fingers crossed*). this is my 3rd day and the bluetooth works great. the phone connects with the car instantly, my phonebook works and i can make and receive calls without losing the connection.
so maybe updating the rom will help you too.

Sorry, it's been a while since HTC answered my questions but since their answer was quite disappointing I had no rush to post it.
Summarized they told me the HTC BH S100 was not compatible with the Touch HD even though I pointed out that it's in compatibility-list of the Diamond and both are running the same Chipset and OS and that it works fine after the first pairing.
As I'm tired of reconfiguring my phone I'll wait some time to flash another ROM. I hope WM 6.5 will be released soon and fix this problem, too.

Bluetooth still doesn't work properly!

My X1 has a very annoying problem with it's Bluetooth. During a call using Bluetooth handsfree the phone will drop the Bluetooth connection, leaving the call connected so annoyingly the caller can hear me cursing the unreliability of my phone. I then have to finish the conversation holding the phone to my ear without the headset.
I called Sony Ericsson, who told me to update the firmware. I did - to R2AA007 - makes no difference. They then said it was a defective phone, so I got a new one sent to me...
...this one has worked great for a month, but yesterday the battery ran almost flat and whilst on a call using handsfree it started playing up again. Now it does it all the time again, even though the phone has been fully recharged and rebooted.
I have been very careful not to change any settings with this second phone, no installs of anything. This is a Vodafone UK phone if it makes any difference. Any idea how I can get this working again? Even without the handsfree connected I can see the display flash 'Bluetooth on' at random intervals indicating that it keeps dropping. Sony Ericsson say that this is not a firmware issue that needs fixing now - what do you guys think?

there are many posts regarding your problem. one thing is for sure,you are not the only one. look here http://forum.xda-developers.com/showthread.php?t=480698 and here http://forum.xda-developers.com/showthread.php?t=471181 here too http://forum.xda-developers.com/showthread.php?t=448703 i have my mbw-150 and my hbh-pv712 connected at all times to my x1 the watch is always connected but my headset disconnects randomly as you mentioned even during a call. there is no problem with your phone it's a software issue.

Thanks for the links. What annoys me is that Sony tell me there is no problem and they won't report the bug to their firmware team because "it's been fixed in R2A". This isn't the case, and it doesn't give me much hope for firmware R3A.

Same problem here
I experienced the same problem. Got my X1 in december 2008. Problems started in mid Januari, about a month of good Bluetooth operations, it started to give problems. During a call the Bluetooth connnection is lost, but the call stays open. Can reconnect Bluetooth again during the call, but after some time (sometimes seconds, sometimes tens of seconds) the connection get lost again.
Was glad when the new firmware arrived in Feb 2009. Download it, and the problem was gone fore about one month. Mid march the problem started again. Downloaded (the same) firmeware version again and the problem was gone again for some time. Last week it reappeared again
My conclusion: the Bluetooth bug wasn't corrected in the latest firmware version. Just reinstallation of a new firmeware version resets the phone and the the problem is gone then for some time.....
Seems that there some kind of an internal timer/counter that corrupts good bluetooth operations. I don't want to reinstall "firmware" every time again because I have to reconfigure my phone then every time, which takes a lot of time.
I hope that Sony finally will correct this most irritation bug!!!!
In the mean time I use a Bluetooth restart programme that "turns on" bluetooth every second. This helps moth of the time.

This works for me
In the Bluetooth-Device-Manager tap and hold the stylus on the headset you want to use until a popup is shown, then select use as headset. This worked for me when i have had some problems with one of my headsets supporting more than the "Handsfree-Profile" .
=> better connection under R1, best connection under R2(using R2 since official release)
Good luck WOODY

Hey Guys,
I think i have the solution for the bluetooth problem. i had my Xperia since 11/2008.
i never had a problem with connection when i used my headset. the problem was with the I-Drive disconnection randomly.
I flashed multiple roms from Itje and Jack with the same problem always.
now for the past 2 weeks i have been using Itje V5.5 with no problems what so ever.
the key is to turn bluetooth off in the comm manager everytime you wanna install new programs. i truly believe that installing software with the bluetooth on disrupt something ???
Hope that helps.

Honestly, it make no sense to me....

try it!! it will work ...

@mdshaded
I hope youre kidding, I've had BT problem (BT turns off) since I got this phone last year.
With Itje's WM6.5 RC1 I still have the same problem.

I am not Kidding, I tried all cooked and original roms. I had a pocket PC phone for the past 3 years: Trinity, Kaiser and now the Xperia.
Again my dropped BT Connection were with my Car BT system, never with my Stereo BT headset.
try to hard reset and then install Itje V5.5 and keep your BT off until you are done installing all your programs then turn it on and report back.
Cheers

I had tried more phones (Eten M600, Asus P525, Kaiser, X1), and did a lot researchs and only HTC's one (Kaiser, X1, Diamond, TP, HD ...etc) gives such issue. Not on my Asus P525 and M600. And I had tried many A2DP devices (Sony: DS-205, DS225, DS970, DS980, Clip-D Radio, Jarba (forget what model), JVC-BT1 (car system)) and only HTC devices give me issue.
And your suggestion of turn off bluetooth while software installation make no sense as installation only perform files coping + registry registration which I don't see any relationship from BT issue.

Dear Jack,
I know it does'nt make any sense. but i had this problem on other devices and was always corrected with a cooked rom except with the Xperia..
there is nothing to lose.. just try it..
my phone had no single dropped connection for 2 weeks now.
All the Best.

what bluetooth issue, ive been using hbh ds-200 since ive got the xperia (used on buses, around the house and alot of places) works great and has a further distance than p1i but only has an issue of button compatability. i think it could be the the bluetooth device ur using or the lack of software. may be wrong completley but hear me out ive had it rnning for ages with music on or durig a phone call cause i cant be bothered to pull out of its case to avoid scratching the phone (i know its stupid) but like i said it is working, for me atleast

same problem ...
I'm experiencing the same problem:
my X1 periodically drops the connection to my BMW iDrive while I'm speaking. But, when I'm not in the car I'm using a plantronics voyager 855 and never had a problem ! So there seems to be a problem with specific bluetooth devices.
Before the X1 I had a touch diamond and it worked without any problems with the same iDrive.
Thomas

Dear Thomas,
i am glad that you mentioned your problem with the I-Drive. I did not have a single drop in BT Connection for 2 weeks now. I truly believe that installing some software impairs the BT connection with my I-Drive.
Again never had any problems with Headsets.
My I-Drive Version I believe was newer than V.25.
Cheers.

[Q] Question about issues with bluetooth in EC07

Good morning fellow forum member. I've recently begun having some significant bluetooth connectivity issues with my continuum and Ford Sync system in my 2011 Fiesta. Now, before you start ranting about your loath for microsoft or Ford please hear me out. In theory, the Sync system, combined with bluetooth technology, is a great way to go hands free. It also allows for the coordination of the system and Pandora & Stitcher Radio on an Android phone.
Anyway, lately my bluetooth connection to my car has been causing FCs on my phone. They are the type of FCs that cause the "long-short-short-short" haptic feedback but doesn't throw a pop-up message describing the cause of the FC. So, when the feedback occurs the phone will sometimes lock up but it always disconnects the bluetooth. I don't use bluetooth in any other fashion so I can't be positive that it's not an issue with the car's bluettoth system.
With all of that said, is there an inherent issue with the bluetooth system on our phone? If so, is there a fix for this? I'm currently running the EC07-clean_new ROM. This was installed over the SCH-I400-EC07-FROYO-REL-PRODUCTION ROM. My broadband version iss:i400.0.6v.EC06, Kernel 2.6.32.9 and build SCH-I400.EC07.
Any help that you brilliant folks could offer would be much appreciated.
Thanks,
Ray

I run bluetooth constantly (it's the only way I talk on my phone, driving or not.) I've never run into this issue. Have you recently downloaded any new apps? I found that there are some apps that simply don't play well with our phones. Especially radio based apps (I.E. the issues a lot of us were having with gps based apps, or gps losing it's lock, after a while. Wireless tether 3.06 beta completely screwed my phone up... etc). The only other thing I could suggest is to drop your phone from the sync, and reconnect it... I do this with all my bluetooth devices at least twice a week as a matter of course. And if you want to experiment to see if it's sync or your phone, assuming you have bluetooth stack on your computer, you could connect it to your phone. Other than that, maybe find a friend that has bluetooth and connect it?

Thanks for the suggestions. The most recent app I have installed that uses a radio is the new Stitcher, though I have been having some issues with "My Tracks" FCing but I think that is another issue. Anyway, prior to your reply I found an app on the market called "bluetooth fix repair" It's free and I gave it a shot. I've also deleted the phone from my car's list and repaired them. So far so good. I have a bluetooth stereo headset I'll have to try. I probably have too many apps to begin with. I'll see about deleting some of the ones I don't really need.
Thanks again,
Ray

I think you should be good with rourine disconnect/reconnect. Asfor too many apps, the only thing rhat matters there is storage space. Android wint let you run "too many" at once. Itll delete from ram as needed. I was just saying that certain apps dont seem to play well with others. But that is an android issue, not your phone in particular.

I'm totally stumped here. Yesterday I decided to reflash my phone. I figured any issues might be ironed out. It must be an app issue, although it is going to be a PIA to uninstall then reinstall each app and test the BT after each app install. I thought that it might be the trailblazer101 car cradle, desk cradle or the sticher apps that were giving me the problem but that doesn't seem to be the case. Maybe I'll try replacing the BT files with the ones from eclair to see if I end up with the same trouble. Any idea if that might cause more problems? Are the BT files android version specific?
Peace
EDIT: I've not swapped the BT files from eclair but I did spend an hour or so listening to Stitcher radio via a bluetooth headset. It doesn't seem to be a BT issue. More likely an issue with the connection to the Sync system itself. Connecting via bluetooth is no problem in the car. It's not until I attempt to engage a function other than the phone that an issue occurs. I may try to reflash the EC07-clean ROM and see if there was something with the EC07-Clean_new version that I've been running for the last few weeks.

OK, the BT issue seems to be corrected. I flashed adrenalyn's EC07-clean ROM and that seemed to do it. Something must have gotten corrupted. So, issue resolved...i guess.

N4 bluetooth won't sync with car

Hey all,
Recently got my n4 and am currently running cm10 nightlies on it, but today I picked up our new car (Hyundai i30 premium) which has bluetooth built into the audio system and I can't get my n4 to sync with it properly. My partners Desire HD syncs no problems and all her contacts phone book everything shows up fine. My n4 wouldn't even sync originally then I just kept retrying and eventually it synced but nothing really works, music won't play through the speakers (the audio system just sits there waiting for music and nothing happens) my phonebook etc don't show up (after me allowing them permission) I can't even make calls.
I have heard that the n4 has some bluetooth problems but nothing this bad, anyone have any suggestions that I can try? Happy to go to another ROM if that will help??
Thanks,
Hosh

this build has serious BT issues. i can't even find a mouse that works. wait and see what the 4.2.2 update brings.

I own a Hyundai Elantra GT which is the US version of the i30 - I didn't seem to experience any issues when I paired it this morning, but I"ll double check when I get out of work this afternoon that the contact sync is working. I am, however, on the stock rom.

I own a 4 day old Dodge Journey and it pairs with no issue to Uconnect.
Try a different rom?
If thats not it, then its your hardware.

The new bluetooth stack in Android 4.2 is causing a lot of issues. Personally, I don't have any problems connecting to UConnect (Jeep Grand Cherokee) or my SmartMini (bluetooth music streaming).
I am waiting on delivery for my MetaWatch, there have been complaints that 4.2 isn't connecting well with it but I guess we'll see. CM10.1 users don't seem to have as many problems. I'm running Xylon w/ Franco r53.

I had the same problem with Chevrolet captiva until I have installed custom ROM and is working perfect now.I have tried every custom ROM and is OK with all.

I have this problem but there is a way around it (for me anyway).
Download Bluetooth file transfer from the market.
Delete the connections with your car. Both on the phone and your car.
Open Bluetooth file transfer. Select the Bluetooth screen.
Make a connection. The default android Bluetooth will ask for a password. Don't enter it. Instead go to your recent apps and select Bluetooth file transfer. Put the password in the request screen the app supplies.
Bluetooth file transfer should pair the devices and make a connection.
Once done. Kill Bluetooth file transfer as you won't be able to exit.
You can then uninstall Bluetooth file transfer if you want (although I tend to keep it for when I change ROMs or have to do a factory reset etc).
Hope this works for you

Hey all,
Sorry for the late reply, been away for the weekend. Thanks for all the advice, tried them all and no luck. Will try out a mates n4 tomorrow and see if he has any luck syncing with the car, if he does might just flash roms again.

after flashing a new rom, I had problems pairing w/bluetooth and connecting w/wi-fi. I fixed the problem by restoring my system settings w/titanium backup thanks to someone's suggestion.

Seems the only thing that worked for me is when it asks to sync my phonebook I have to say no, if I say yes it seems to freeze the whole thing. Makes me think if I click yes I might just need to give it 10-15 mins to sync, might try that tomorrow. But for the moment at least it's half working!

[Q] Bluetooth disconnecting on i9505 running CM11 later than 2014-08-04

Hi!
I have been running CM for years now. For the first time the nightlies aren't working good for me. The cm-11-20140804-NIGHTLY is working great, but as soon as I installed any of the newer my bluetooth starts disconnecting. For instance, the cm-11-20140817-NIGHTLY caused the phone to restart several times a day. It also caused the bluetooth to disconnect and the wifi acted very strange.
The latest rom I tried was cm-11-20140831-NIGHTLY. The bluetooth disconnected almost immediately and I went back to 0804.
Any ideas?
Thanks in advance!

Hi,
I've made similar discoveries regarding only bluetooth connections. :crying:
I'm using nigthlies for a long time.
With cm-11-20140724-NIGHTLY-jflte S4 GT-I9505 and my car (BMW E61, 2006) connects perfectly. Later nightly roms aren't working with my car.
Any hints?

You can use the latest Snapshot: cm-11-20140804-SNAPSHOT-M9-jflte.zip
In this one bluetooth is working correctly.

Same thing on SPH-L720
I noticed that the same thing happened with my Sprint Galaxy S4 (SPH-L720), on Cyanogenmod and Paranoid Android. I didn't even think to flash an older version of the ROM. Guess I'll do that since I miss having Bluetooth connectivity in my car.
Does anyone know why this started happening in recent builds, though? I haven't seen anything about it.

Has anyone tried the newest M12 snapshot to see if resolved their issue? I have the same issue on multiple M11 snapshots.

I have the last mahdi rom and use a bluetooth speaker for my bath. I don't have this problem. I don't know maybe they have another bluetooth driver or something

I just updated to the M12 Snapshot and managed to reconnected to my car about 15 times without any issues. I'll post back if I see other issues with this update.

CM11 M12 Bluetooth/WiFi Issue - Fix?
Apologies for the hijack, as this may not be entirely similar to the OP, but the solution could help.
I was experiencing wifi disconnects when I would toggle on bluetooth, when using CM11 M10 or higher.
With a clean install of Cm11 M12 (reset/new user + formatted /system), I finally worked up the courage (and kinda' understand what it is I have done) and updated the bootloader (not sure if necessary) and the GSM/LTE modems to the latest - XXUGNK4 - from here http://goo.gl/RziHz1
I was previously on XXUFNC6 (from the stock ROM), went to XXUGNI2 (closest to my country based on this thread http://goo.gl/TQi3gz) but that did not work either. So I went straight for the jugular, and installed first the bootloader, then the dual modem pack for XXUGNK4.
So far testing has yielded positive results.
Streaming audio (320mbps) via BT plus downloading some ISOs from MS (speed between 550KB/s to 1.01MB/s), and so far no issues.
Not saying this is going to work for anyone else, or solve the OP's exact issue, but it seems to for me.
-P
