Bluetooth bug with Car Kits. Turns off and on and off and .

I searched and didn't find any previous postings regarding an issue with Parrot and Audi Hands Free (Bluetooth) car kits and the TyTn.
This issue is only with the TyTn and the Wizard devices work fine.
It seems to pair fine with the car kits but 5 minutes into usage...the TyTn turns the bluetooth off on the device.
Then about 1 min later, turns Bluetooth on again. The cycle then begins Off and then On ....
Here's a link on the Parrot forum.

I've got the same problem with my Seat Leon (new model) bluetooth carkit !!!
I think it's the same module as in the Audi (all VAG related cars).
It's very irritating !
I hope they will fix it soon....

Er... not followed as far as parrot (down for maintennance) BUT
I've found with my Seat Leon kit that the phone needs to remain in a fully powered state - you can't put it into the sleepy state by the power button otherwise you get the intermittent but eventually endless dingling of it connecting and disconnecting.
Best way I've found is to leave it on asking for a password with the cover on.
edit: Should just point out that you also need to turn off any power off settings - except for the backlight.

I'm going to try this !
I hope that it works.
Thanks anyway.
What kind of Leon do you have ?

I've got an A6 with BT kit and am having this problem. I cannot make/receive a call whilst running my BT GPS device & TomTom, although from reading this the issue may be the Audi kit anyhow.
Are there any fixes available - be it HTC or Audi? Or are there any work-arounds, such as add-on software for the TyTN??
Please help - it is driving me mad. Spoiling what is otherwise a great piece of kit.

I have been having this exact problem with my Audi A4 with Audi Bluetooth.
I did wonder if it was in some way connected with the phone going into sleepy mode as it is being powered by the phone battery.
Also, the bluetooth stops responding after 5-10 minutes, but if I am continously using the phone, it seems to be ok.
Therefore, I think I need to buy an in car charger, and see what happens...
Has anybody else tried this that can confirm it works?

Just a quick note to Paul_o
My Audi A4 / SPV M3100 / Tom Tom / Bluetooth GPS work fine together.
If I am in Tom Tom, and get an incoming call, the little call window pops up over Tom Tom, Tom Tom carries on and the phone audio is routed through the speakers - the only irritating thing is that the Tom Tom lady keeps interrupting... :wink:

Hi,
I'm using Vario 2 with Audi Bluetooth and also having the BT ON - BT OFF issues.
These are my findings.
- Without JETWARE software:
- BT goes ON and OFF in the car regardless of the VARIO 2 being on or stand-by, or the phone being battery powered or connected to the car.
- Once a conversation is started the BT connection seems to be remain ON.
- With JETWARE software
- If I leave the screen always on the BT connection stays always ON. Only backlight automatic switch-off is selected
- I have tried several screen toggle programs (which claim that they only power down the screen) but the BT goes OFF in the car after a few minutes.
I'm happy to test any other proposal.
Cheers,
C

What version of JetWare are you running, they have a beta which has settings for the Audi kit, this may help, there is also a registry setting that is meant to change the power settings when bt is connected. An extract from an email conversation with Jetware...
We have also addressed the power issue, but this fix requires a registry change. Please create a DWORD registry value in HKLM\Software\JETware\AGExt named InSessionPower with a value of 0 (valid values are 0-4, with lower values indicating greater power availability). This will tell the OS that the Bluetooth device should stay at full power while it is in a Hands-free session.
Not sure if this will help, my Hermes is ariving on Monday, I'm was hoping that all the problems i've had with my magicain and the audi kit would go away with the Hermes, but maybe not.
Give the key a go and let me know

Hi dh,
thanks for your reply.
I haven't installed the Beta version yet. However I have changed the registry setting and will test first thing tomorrow. If this doesn't fix the problem I will try the Beta version with the Audi setting.
I'll keep you posted.
Cheers,
Carles

Hi dh,
I have tested the two proposals (Change in the registry and the Beta version + Audi settings) without much luck. The BT connection with the car keeps going ON and OFF when the phone is running on battery.
Have you got your Hermes? any luck?
Thanks,
Carles

Got my Hermes (Orange M3100) a couple of days ago. I've installed the JetWare extention, and without the InSessionPower set the connection is dropped. So far with the setting applied it has stayed connected. I have had other problems like not being able to make calls etc, which is a bit of a issue. I need to do some more testing, as i've been messing with the phone a bit.
I'll update here in a couple of days
Must say i'm very disapointed with the phone regarding this. A couple of weeks ago i had a Wizard which worked flawlessly with the JetWare extention, no power issues, calls made and received without a single problem. I wonder what has changed with the bt implementation between the Wizard and the Hermes?

Hi dh,
You will see from my previous postings I have had the same problems too.
It should be noted, though, that the Vario (wizard) worked flawlessly with the Audi A4 Bluetooth without Jetware software.
Has anybody been able to prove there is no problems if the phone (SPVM3100) is powered whilst in the car?
Cheers
Mark

I have a factory fitted hands free system in my Vauxhall. Every other phone you can think of works with it...EXCEPT my XDA mini. It seems to pair up, but there is no signal showing from the carkit. It might work for a minute and then it drops out. Is it the XDA or Vauxhall that's at fault? It seems that nobody knows the answer and I paid serious money for this bit of car kit. I like the phone, it really is annoying. I have tried another XDA mini as well and that doesn't work either. Does anybody else have a Vauxhall with the same built-in system and not connecting?

Markee
I've had the phone plugged in without the registry entry and it seemed to be ok. If I can get to a stage of a working solution i'll test again without the registry entry and with external power.

I'm guessing that since they went from BT1.1 to BT2.0 they had to make a new stack.
My Wizard worked PERFECTLY on my Parrot, my TyTN is almost useless on it.

you make a very good point ScottC, that'll be what it is.
Just driven home and could not make a single call with Jetware installed. Removed it and i could at least make a call, but i didn't get any status info or phone book. I didn't get a chance to leave it connected without Jetware for longer enough to see if it disconnected without external power, i imagine it will. I will test some more later/tomorrow. I'll also send an email to Jetware to see what there thoughts are regarding bt v2.0 and their product

Hello,
I have an Audi A3 with the factory fitted Phone kit but without the Audi Craddle so I'm using the Bluetooth connection.
I have tried the Vario (Wizard/QTEK 9100) and Vario 2 (Hermes/TyTN) and had similar problems with the two of them. Once the connection is stablished I can make and receive calls without problems. The issue is that the BT connection goes ON and OFF without an apparent reason.
The only thing I have seen is that when the Vario is kept on (only the backlight is off) the BT connection normally stays ON, regardless of the phone being powered or not.
I have tried Jetware, the Beta version, the registry entry, programs to switch off the screen...but haven't seen any real difference.
I have bought a bluetooth USB stick and will do some test at home to see if the problem is with the car or the phone.
I called T-mobile and they said it was a faulty phone, but I don't think so.
Keep the postings, we might end up finding a solution
Cheers

Try upgrade the BT software. I had the same problem after that i upgraded de Parrot software. Now i have the version 4.16

TyTN Bluetooth | Random car disconnect

Hi all,
I know there are plenty of threads about the TyTN bluetooth issues, but my questions differs in two ways which I have yet to come across:
I do NOT have M$ VoiceCommander installed (and don't want to install it)
My bluetooth issue relates to my car's handsfree feature - my TyTN randomly connects and disconnects. Apparently Audis, VWs, BMWs, and Acura's all suffer from this this problem.
The situation:
When I start my car, the phone will successfully merge with my TyTN. Approximately 30 to 60 seconds later, the connection will be lost. Shortly after that the connection will re-establish itself, then it will disconnect itself a short period later. This pattern repeats endlessly.
I've tried each of the following Tweak programs but none have helped.
jetwaremobile
Tweak2k
HTweakC
I've heard that there is some kind of registry tweak that will prevent the bluetooth stack from disconnecting from my car's handsfree feature, but after looking for about 2 days now, I can't find it. Can anyone help?
thanks.
jm

Yep, got exactly the same on my BMW 630....
Can t find any tweak but....
I am a heavy email user (thru BlackBerry connect) and I noticed that
the higher the number of messages stored, the higher disconnections appears.
At the same time, the TyTn is slower and slower....so my idea that this is related to some timeouts somewhere....
For your complete info, the MS bluetooth stack in my previuos S100 have able to.....immobilize my 630 !!!!!!!!! yes, incredible...
The MS stack messed up with the BMW bt ...and this later would stay ON for ever...even after switching car s power off.
This was sucking the car s battery untill the car would start !...
BMW could not reset the BT module unless disconnecting battery....but...then the active steering had to be re adjusted with the proper BMW computer...
This is a real story.

I have the same problem with a CK3100 kit, don't have a solution, but would like one, didn't have this problem with a Jasjar nor Wizard

TyTN bluetooth | random disconnect when using car handsfree - more details
Thanks for the replies so far.
Although the following thread did not help me with my problem, it might help one of you. If you're having problems mostly related to issuing voice commands using M$ VoiceCommander, I think there *might* be a solution in that other thread for you.
Just to reiterate my problem; my TyTN keeps randomly connecting and disconnecting from my car's built-in hands free bluetooth device.
There was a time when if i managed to made a call after first starting the car - before the first random disconnect - the phone would remain connected until the next time I started the car. That no longer appears to be the case.
-jm

I solved the BT problem with my Orange SPV M3100 by setting it to never switch off the display automatically (only switching off the backlight after 20 seconds or so). I also use an in-car charger to power the TyTN. The car is an A6 with RNS-E (BT enabled) and TyTN works fine and never loses the BT connection as long as the display is active.
This is a mid-term solution though and I'm still eagerly waiting for a ROM update that will solve the problem for good.

Has anyone tried a ROM with aku 3.3?

Yes.
And on my CK3100 I now no longer get disconnects. I did have to uninstall jetware as it wasn't reliable. My TyTN now connects perfectly and no longer drops.
One thing I did find is that the TyTN hates it when more than one handsfree device is in its trusted list. Make sure that the ck3100 is the only handsfree device paired.

I've tried changing the automatic switch off setting and it made no difference on my SPV M3100 (with Parrot CK3100) - I reckon that the external power is what fixed your problem (this has worked for others too).
Sadly it's not a convenient fix as I like to leave my phone in my pocket when I'm in and out of the car. Orange say there is no 'issue' so there's no sign of a ROM update but HTC know of the problem but I have to wait for Orange to release their ROM update. I can't use the HTC update. If only us Orange users could tell them enough times they might listen now that some AKU 3.3s are being released. Orange technical department won't speak to end users like me - they have actually refused to discuss it with me and just pass messages back and forth from customer relations. Any other ideas?

A solution - thanks to Parrot
Yippee - thanks to Parrot I have got a solution to the TYTN / CK3100 problem (my phone is the Orange SPV M3100).
As Orange and HTC can't find any solution I kept asking Parrot for ideas. Their excellent customer service department tried various settings which made no difference until I was offered a trial of some beta test software called VCF creator. Once you have the VCF from the PC's Outlook you just need to beam it by BT across to the CK3100 and alter some settings (takes 5 minutes maximum). The small sacrifice is that you don't have auto-synchronisation so if your numbers change a lot you will need to do another VCF upload. The extra bonus benefit is that all your numbers will be grouped together. So, for example, you access someones name and then you can see their mobile/home/work number rather than having a separate line in the main list for each phone number. The problem is a result of how Windows Mobile phones provide the data. With this bonus you can then use voice activation to input a name followed by a keyword mobile, home, work etc. Fantastic!

If you use the Jetware BT software you can do the same thing e.g. beam the whole contact list in one go and then set the Parrot to not sync by choosing the Ericsson No Sync profile. This is how I have mine set up, also with the Jetware software it sends over the Service Provider, Battery and Signal strength settings to the Parrot, something which the native stack doesnt do.

Solution for this
Hey all, i have purchased a parrot 3100, the software in it was 1.6, i had the same problems but it's greatly and successfully solved using the new jetware 1.3 . i don't know if i can post some linx here, but here you go, if this is illegal for this site please remove them

How do you stop BT turning off ?????

Hi,
Can't find anything in any other threads so here goes..
My M3100 (TYTN) turns bluetooth off when I turn off my Sony HBH 300 BT earpiece.
It doesn't happen everytime, maybe 50% of the time. It wouldn't be a problem but during the working day I connect and disconnect maybe 10 to 20 times and when I get back on the road and fire up the earpiece I suddenly find no BT.
I'm normally not in a place where I can safely stop to go through the connections screen to re activate it....
Not had this problem with any other phone, Nokia, SE etc...
I think it also happend once or twice after turning off my TomTom One whilst running the traffic BT connection to my phone...
It is getting to be a pain, so much so I'm considering using a OLD Nokia instead of the M3100. Only advantage is the M3100 allows more than one BT connection at the same time although you do have to connect the BT earpiece before connecting to the TT One unit...
Any ideas how I can stop it turning off without ME actually turning it off, never happens anyway, I just leave it on...
HELP !!
Phil-w

I have a similar problem and would love to find an answer before my 30 day return period is up! I haven't been able to find out WHY my BT radio always shuts off, but about half of the time I get in my car the BT is off. This - and the MS Voice Command hack not working with my particular HF - is going to make me return this thing.
BTW, I have Cingular 8500 with stock WM5.

Worked for me
Hey guys. I had a similar problem a while back.
I had installed a comm manager, and my BT was randomly shutting off. After getting some responses, I uninstalled the updated comm manager, everything has been working fine ever since.
I would recommend following the same course of action. If you don't have the original installed, maybe try installing a new one.
I recommend keeping the phone. It's great. There is SOOOO much you can do with it. If you are unlucky and got a lemon, that's a different story.
But I do not think this problem is common... good luck.

Last week I updated my ROM to the latest official AT&T release, and my BT problems *appear* to be solved.

Bluetooth not staying on - same problem as Tracy and Matt Blog

My Xperia X1 is great. The keyboard is a refreshing change from the orbit 2/polaris.
Problem - Bluetooth does not stay switched on. This is most apparent when using my Parrot carkit because it does not automatically connect due to the bluetooth being switched off. I have looked through the settings to no avail. Any suggestions? Anyone else with similar problem?
Also the screen switches itself off at such short intervals - possibly to help battery life but it makes reading web pages frustrating at times.

The screen switching off can be changed or turned off in the phone settings.

Thanks for that. The bluetooth issue is real although it may only be on the branded uk ROMs. Anyone else with a similar problem - when I click bluetooth on it stays but as soon as you open up settings or programs the icon disappears (switches itself off). Any bright ideas?

Bluetooth just turns off...
I have the same problem.
The Bluetooth just turns off.
Its a real problem, and nothing i can find either talks about it... or in any setting.
Anyone know of a fix?

My friend at SE Sweden told me that a new FW will fix this. They know about the problem and are working on it.

RTFM - switch bluetooth on + soft reset device = bluetooth stays on.

This does not fix the issue. Soft reset after enabling.
Again... I contacted SE... and was told.. "We are aware of this and it has been passed to developers to create a patch in the form of a CAB/flash that will become available on the SE website under support."
So... timescales... she said.. it won't be weeks as this is a new phone and any issues are taking priority.
Sit and wait... if you need it and use BT constant... Hold fire on buying one...

What works for me is switching off the wifi - my bluetooth has stayed on every since.

I installed the Touch HD TF3D and hey presto.. WIFI and Bluetooth work as wanted with no probs.
So... What does this package do?
any Bluetooth settings or power?

Hello,
i have a german rom ( 1.02.932.3 ) and i have the bluetooth issue too.
daniel

I think this is just a small bug in the SE BT stack. SE phones have an option to turn on BT for 10 minutes or so, maybe this setting was used in the first roms. I hope SE will fix this.

I've got a 02 SE X1 just out, I have the same issue, I can connect to my Parrot 3200and it works fine, get back in to my car sometime later and BT will not connect, 1st I tried switching off the phone, then resets, and finally which works, switching off the BT and back on again (although BT still shows as being on in Connection manager), after that I can finally get a BT connection to the car kit,
Is anyone getting the same problem ?? and is there a patch yet as its really frustrating to do this every other time,
Thanks Mark

Hi Mark I have a Parrot Bluetooth carkit (3200 the same as you). It is working and syncing beautifully with the X1i just as it did with my previous WM devices.
I dont go through the stages you mentioned anymore but bluetooth only stays on if the wifi is kept off.
Hope you get yours sorted.

Wifi is always off ? I've emailed SE tech support so it will be interesting to see what they say

Does anyone have a problem with the HBH-DS980 bluetooth headset?
On my X1, it only shows Wireless Headset and Hands-Free services. What about A2DP and AVRCP?

I never use wifi, but I still get this problem pretty regularly. It's the only thing keeping me from using the phone.
Also, has anyone else noticed a bug where the email signature you set will not be retained after a soft reset? It always reverts back to the stock Xperia sig.

I have a Xperia uk version and had the same experience, bt went off randomly. I installed Touch flo 3d and now works fine. Switching on and off WiFi has no influence on bt in my case. Also tried bt on + soft reset and still bt went off sometimes.

i have same problem
i have the same problem with the bluetooth, i cannot connect to my car kit (which is SE also by the way!). After contacting SE i was told to wait for the new firmware coming out on the site... this is so frustrating!! how can such an expensive phone have this silly problem??

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.

@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.

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.
