[Q] While connected on Bluetooth car kit: Screen stays on during and after call - Defy Q&A, Help & Troubleshooting

Hi all,
Last week I updated my stock defy towards CM7. So far everything works great except if I hook it up to my Bluetooth car kit the screen never times out during or after a call. This is really annoying while I commute more than 2 hours a day and call a lot in the car. Now that the display is turned on and remains on, it’s draining the battery a lot. A work around is to manually switch of the screen with the power button. But that’s easy to forget.
The specifications:
Model:MB525
Android:2.3.7
Mod version: cyanogenmod-72-20120304-NIGHTLY-Defy
Build nummer: GWK74 – cyanogendefy
Car:
BMW Idrive 2011
BT module: TX-003.005.004-003.004
Multimedia module MX-003.005.004
Problem:
While connected on Bluetooth car kit: Screen stays on during and after call.
I already tried most option I could find on the phone, but none seems to have effect. I also already connected the phone with Nokia Bluetooth earphone, and that works fine. After the set screen time out, it works and times out while connected on Bluetooth.
Any advice or help is more than welcome. If any further info is needed, please say so.
Cheers,
Bram

Did you manage to find the cause of this problem? I'm having the exact same issue with my HTC Sensation (on Frankenstine AOSP ROM, android 4.1.2) and my 2011 F11 idrive (MX-003.005.004, TX-003-005-006)
Thx.

Hi, no I didn't find the root cause. But after updating to newer rom the problem was solved. Hope this helps?

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.
http://www.parrot.biz/forums/english/viewtopic.php?id=2667
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....
http://forum.xda-developers.com/viewtopic.php?t=58789&highlight=
:wink:
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.

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?
Markee
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

bluetooth car kit

hi.. i hve a skoda, octavia 2, it has factory installed bluetooth car kit, i can easily connect my Herms , but it keeps disconnecting and reconnecting every few minutes, I tried to upgared to WM6 and its same, I cange my bluetooth control unit at Skoda , and its same. the car kit works fine on any other phones like Nokia or SE. the problem is only with HTC devices. any idea ?
not a single reply !!!
This is a common problem with the TyTn, there are plenty of other threads here with exactly the same problem. I have a Parrot C3000 Evolution car kit and am using a LVSW WM6 ROM (see sig) which works most of the time (better than other ROMs in my experience) - although I experience the following all the time;
Bluetooth turns itself off (on the TyTn)
Bluetooth is on, but the phone won't connect to the car kit
Connection to the car kit gets lost after making a call
Connection to the car kit gets lost when dialling a number
In most cases going to connection manager and turning bluetooth off then on usually works, sometimes (rarely) I have to soft reset the phone and once in a while I have to soft reset the phone and the car(!). When it does all connect it works very well, I also use MS Voice Command and with the various fixes applied I get announcements, voice dialing etc. all working perfectly.
My problems with bluetooth are limited to the car kit though, I also have a TomTom bluetooth GPS dongle which works perfect all the time.
thanks forza
thanks a lot, at least I don't feel lonley with my problem.
i found this, which works great with my car kit.
www.jetwaremobile.com it costs, but there is a 30 day trial to see if it will work with your car kit.

I have found that my 3200LS Color works great as long as I have unlocked my phone BEFORE turning ignition on. Have you updated your Parot firmware to latest version?

Hero will not automatically reconnect with MMI / Audi A6

Hey Folks!
Great work here... Coming from WM/Symbian/Blackberry I'll try Android for daily use now.
My actual only problem is, that my Hero won't reconnect with the bluetooth System MMI of my Audi A6. Pairing is fine, manually connecting works, but I found no way to automatically reconnect the Hero with MMI when I enter the car and turn on the ignition/engine.
Every other handset does this comfortable reconnect (Nokia E71, Blackberry Curve 8900, Palm Treo 750...).
Is this a problem of my Hero or of Android itself? Is there a workaround to solve the problem to get an automatic reconnect?
Thanx!
Tom
Maybe the problem with the Hero. I cannot connect the Hero to my BMW I-Drive at all.
My G1 connected to my alpine stereo fine, when it did a small microphone appeared on the stereo along with the bluetooth icon. The hero pairs, the bluetooth appears and the phonebook is browsable, however it doesnt display the mic icon on the stereo. I think this means it's not using the stereo to pick up voice. I need to test more.
It would appear that there is something different about the bluetooth stack on the hero. Which is worrying with it being a hybrid android build
There is definitely something different. My old G1 pairs and works flawlessly with my BMW I-drive. The Hero pairs but won't connect.

That's positive. Are your contacts on your SIM or straight from a Google account? Do you have the latest MMI?
I'm about to take delivery of an A6 with HDD 3G MMI with bluetooth and wondering what to expect.
I have some issues on Skoda Octavia as well. As Skoda/Audi/VW have some things in common, I thought to mention this.
Usually my Hero works fine, but maybe 33% of the times I cannot initiate a call from car bluetooth. It starts to make a call, but fails, on Hero I get some MMI error (have to write that down the next time I get it).
When the error occurs, I can still start a call from Hero and phone audio comes nicely through car bluetooth and stereo. It requires me to turn off the engine and turn it back on to get it working again, however, sometimes it will also start working by itself. Might be that if I initiate a call from phone, it will start working from car controls as well, but I cannot confirm that.
Ik works fine on my 2006 A4 MMI, and I did test it on my new A4 2009 Model coming in december.
No issues, both show contacts and auto connect.
Did you set the MMI device as "trusted"?
Automatic connection works fine with my Audi A6 4f MMI!
After a few seconds I have access to all Contacts through MMI.
No Problems at all..
Cheers, Otze
I just have a Motorola bluetooth/FM transmitter. It's not perfect, but what I have to do is turn the Hero's bluetooth on *AFTER* the Motorola unit is initialized. So maybe enter your car with the Hero's bluetooth off, turn on the car, then once the stereo's booted up, turn on the Hero's bluetooth.
It's a bit inconvenient, but it works for me.
Also, I suspect that when we get the Eclair update, our bluetooth will work better, as Eclair is said to finally include a bluetooth API (which has been missing from previous versions, as Google said they wanted to polish it up before releasing it to developers.)

Bluetooth and Nougat

Anyone else on the newest 7.0 preview and unable to pair their bluetooth with their car?

Right after the DP5 installation, I had to unpair the phone and car (2016 Mazda) because the phone would never connect. It was no where near as easy as that sounds, took me the better part of 30 minutes because of repeated "unknown errors" coming from the car.
The phone paired up just fine but I still have frequent and completely unexplained dropouts on literally every Bluetooth device I have (headphones, Moto 360, car and the list goes on). So far this has been the absolute worst of the previews for BT that I have ever seen.
But then, if you read around here, it sounds like there were a lot of these that had flaky BT hardware. Have not exchanged mine, but that has certainly been my experience since I bought this back in December.
I have no issues with Bluetooth and the latest DP. I have my phone connected to a Kenwood deck.

I wonder if I have flaky BT hardware? Mine was a launch phone and it has worked perfectly in my Toyota since day 1. However I've recently bought a fitbit type band and with that application (veryfit 2.0) installed and connected to the band then if I make a call in car it drops the BT after about 30 seconds with an error message on screen saying 'corrupted probe message'. I can manually reconnect the call (it's still active on the phone) but after another 30 seconds or so it repeats the cycle. Have upgraded to Nougat Dev Preview NPD90G but still the same. Removing the app and its binding (it binds in the app not the phones BT devices in settings) and rebooting the phone resolves the issue. Tried again with a proper fitbit and the issue is identical.
I will RMA it to see if I get another one that works. Now to figure out how to put it back to stock marshmallow. gulp.

I had this same issue, I flashed the system file again and wiped the cache and dalvik. It seems to be ok now.
Check this solution. Pair with '0000' worked for me.
http://forum.xda-developers.com/nexus-5x/help/issue-android-nougat-bluetooth-issue-t3446073
Since switching from my Nexus 5 with 6.0.1 to a Nexus 6P with 7.0 I am also suffering from bluetooth issues. Pairing itself is not a problem but the connection sometimes drops, controls in my car don't work properly, remaining track time is not shown, etc. Haven't even tried to make calls yet. If I can't find a solution I'll probably be going back to 6.0.1.
The proposed '0000' solution is not working for me as I cannot change the PIN on my Seat Leon (2016). The PIN is autogenerated and shown on both displays to be confirmed upon pairing.
Has anybody tried flashing the latest 6.0.1 radio image and use it with a 7.0 system?

Bluetooth issues

I have 3 main devices that I pair to my phone via bluetooth: watch/lg tone/car
The watch stays paired with no issues, but the watch is having issues swapping from the lg tones to the car and vice versa.
Anyone found a remedy for this?
As of now, I have to go into the bluetooth settings of the one I don't want to use and deselect media/phone, then go to the other and select media/phone. And even sometimes this takes multiple times to work.
My previous phone (gs7) had no issues swapping from the two.
Hi,
Did you get a solution ? I face the same problem and can't find any solution...
Just to clarify, when you are in your car and want to connect to it, the headphones are turned off, correct?
Having similar issues... Every time I try to connect to my car (stock Subaru WRX), I have to manually connect and it takes several attempts before it connects. Once it connects it usually doesn't drop though. Very frustrating...

It's not in my car but with the bluetooth device of my motorcycle helmet. The reference is ncom bluetooth kit 3. I have to connect it manually and it takes several attempts before it connects. Sometimes it doesn't connect at all....
I have 2 headset Plantronics Backbeat Pro and Plantronics Backbeat Fit. They both work flawlessly
My Huawei Watch also works.
But my Nokia 616 Car kit wont connect at all.
And my motorcycle hemlet bluetooth kit, Cardo scala rider PACKTALK, connects, but the audio is slowed down to about 80 percent?
Same thing here.
I have been facing problems with a Sony SBH52 Headset and with my Opel Corsa E, stock infotainment system.
It gives me a hard time connecting but when it does it's stable.
I had the same with my gen 1 Moto 360 but after a factory reset to the watch and a reboot it's stable.

Ahem, I seem to be unable to find bluetooth in my app settings. Can you please give me a hint?
It's been driving me crazy these days with my SBH-52 and I want to try this too.
Thanks!
P.S.
I'll also give it a shot with a plantronics pro headset I have to see if it does the same.
Bluetooth profiles implementations, even though they passed certification, are not always made equal! So don't end up pulling your hair if a certain BT device doesn't play nice with another.
Just as an example... Head Unit X had big issues with the initial contacts sync, right after pairing with Samsung phones (already known to sometimes play around some other standards). It would only work after several reconnects. After several weeks of debugging (poor development guys) and reproduction test (poor testing guys) it was concluded that it is a phone issue caused by some wrong timing delays in the process of exchanging information between the HU and the phone. Samsung was informed and the ticket was internally closed.
I have similar problem with Bluetooth Earbuds. Phone simple doesn't "see" the Earbuds. But strange - it can see other Bluetooth devices and other devices can see Earbuds.
I'm sure this is a OnePlus 5 software problem.
Version OxygenOS 4.5.10
i have somhow issue as urs, i have Bluetooth pad lock and android watch, it sometimes connected and sometimes not, i do believe its software issue, im on 4.5.11
Yes, it is strange. After some restarts and on/offs connection suddenly appears
