Hi,
I am using my HTC Touch Pro with an Opel Vectra built-in bluetooth carkit.
All functions, like browsing the address book and call registers, are working fine. However, at random times, my carkit reports no phone. When I then check my Touch Pro's bluetooth status, I see that it is has been disabled.
After manually re-enabling it, I can pair with my carkit for as long as it takes for bluetooth to turn itselves off again.
I've already tested with JETware, but that does not change anything. Also tried the universal broadcom bluetooth stack, but doesn't seem to work on the Touch Pro. HTC only comes with a standard answer that they don't support all carkits and headsets... Since the BT stack on the phone seems to crash, I don't think it's a carkit issue.
Anyone here with the same issue? And maybe a solution?
Thanks and regards!!
Start -> Settings -> Connections -> Bluetooth -> Timeout (tab). Turn off Visible mode set to "Never".
I think this must be your problem.
Hi Freco,
Thanks for your reply! This option is set. However it's not really the visibility that turns to invisible, but the whole bluetooth stack is being turned off completely. Need to fully re-enable it via Comm Manager.
Any other options? Does anyone know if there is a working broadcomm stack for the Touch Pro?
Regards!
Hi,
I have exactly the same problem with a Vauxhall kit, I have tried all sorts of things, but nothing seems to work
try:
start -> settings -> connections -> bluetooth
timeout tab
select 'never' from drop down box
Hi Brendo,
Unfortunately this doesn't solve the issue. Once paired, the connection even works without being visible. It's also not a fixed period of time before the disconnect takes place (can be within a minute, sometimes after half an hour). However, the whole bluetooth icons disappears from the top icon bar and comm manager shows it's turned off completely.
Hope somebody has any other ideas, because the only thing HTC can do is point to the carkit vendor :-(. Since all functionality is there when connected and the phone is turning off BT in some way, I really don't think this is caused by the carkit vendor. I should at least expect BT to stay enabled on the phone.
Thanks!
Yes, same here, BTW I have tried this in my Friends Saab, and the same problem.
same problem here with a Opel DVD90 buildin bluetooth carkit.
With other htc phones it always worked like a charm, but my mda vario IV continuously disconnects after a random time period and shuts down the complete stack.
Try this!
I have the same problem with my opel with original bluetooth-kit (2007). On the touch pro I changed the band and network from auto to GSM, as G3 reseption in this area is quit poor, especialy while driving. It helped for me, at least the last few days. I agree this has been an annoying problem.
I have tried to switch to "GSM only mode" in the past, but as far as I remember it does not completely solve the issue. However, I will give it another shot! Actually I can't figure out at what point it occurs... It can happen within a minute or after half an hour without using any funtion.
Does one of you know if there is a way to do some debugging on the Bluetooth stack?
And has anyone experience with other Windows Mobile 6.1 based phones in this combination (just curious if it's a WM issue or HTC only)?
Furthermore I did some tests with JetWare. You should be able to limit the number of synchronised items then (might be related to this issue). However, it looks like this configured limit is being totally ignored: when I limit my recent call list to 5 with JetWare, it still syncs about 25 items. Anyone tested with Jetware?
I have tried the GSM only mode, this didn't help either
I have now given up and got myself a Nokia E66, which works perfectly.
All contacts are pushed to car, no disconnects and AD2P works so my mp3 ringtones play through the car speakers! Sweet
Word of note, I had issues with N-Series phones, would connect ok, but contacts would not push.
I have the samen problem with my HTC Touch Pro and Saab.
bluetooth pairs just fine with my pioneer bluetooth enabled deck, but the problem iwth mine is once i receive a call sometimes no sound comes from the car, instead the earpiece is still on. but if i initiate the call first sound works just fine and earpiece on the phone is disabled, BUT once the call is ended bluetooth disconnects randomly and the phone takes a good 1-2min to reconnect. i absolutely hate the bluetooth on this phone!

I am having the same problems you describe. Anyone got an suggestions???
I encountered the same problem; first with an opel udp carkit and next with the bluetooth interface software from homeseer.
It has something to do with phone signal loss.
With the opel carkit I noticed bluetooth automatically turns off when the phonesignal switched from 3g to gsm.
I also noticed that in my home, BT turns off whenever I have been in a room with no phone-signal reception.
try this thread, both registry change and attached cab file, reset. DOn't worry if the make visible to all option is unchecked.

I have the Kenwood DNX8120 and it works fine with my Fuze (did have disconnect issues but just updated the Kenwood firmware which should take care of that) but the SMS feature on the radio doesn't work. I know only certain phones are compatible with this feature but on the Kenwood compatibility list there are several HTC devices that work. In any case, does anyone know how to enable SMS over bluetooth on the Fuze?
Thanks
I have the Kenwood DNX8120 in my car and have had no luck getting the Fuze to work correctly. It constantly drops connection. I updated the Bluetooth firmware and that only seemed to make matters worse. It will pair with the Kenwood, but either won't make a phone call or will take up to 60 seconds (or not at all) for the Fuze to recognize I it the call button on the radio. SMS, sent and received call history also do not work.
Have you had similar issues?
I can not get sms working. The only other issue I have is that after a call, it drops the connection. If I get another incoming call, it will reconnect and the radio will ring and handle the call. But, if I want to place a call, I have to either select "set as hands free" of something similar, in the bluetooth settings on teh phone and it reconnects and I can dial. I just upgraded to elite rc3 and the problem is still there. I havn't messed with it enough yet to know if it dials ok without having to bring the phone out of standby yet. I too have updated the bluetooth drivers from Kenwood and that didn't help. I also tried the jetware handfree extension and didn't see any improvement.
I called HTC about this, and they told me it only "officially" supports a hand full of car units. Mostly in the Audi and BMW. They don't "officially" support anything from Kenwood so they were absolutely no help on this. I've also noticed this phone drops all connections except cell and data when it sleeps. Wifi, GPS and Bluetooh all seem to go to sleep with the phone. This seems to make bluetooth pretty useless if the connection drops every time the phone sleeps and needs to be manually reconnected.
I haven't seen it drop the bluetooth connection during sleep. I see that the Kenwood supports some HTC devices but not this one specifically. The other wierd thing is that the first time it pairs it shows the battery indicator but after the next connect it doesn't show it. It shows the battery icon but shows it empty. The jetware extension however does fix that. I will play some more with it and report here.
After resetting my phone to AT&T's original setup, I am experiencing the exact same functionality as you. It now sync's my call history and phone book. No voice dial support or SMS yet. (These have never worked with any of my phones) It will disconnect after a couple phone calls and I have to set as hands free to reconnect. Also, mine still looses the connection to the unit when it goes to sleep. I'm keeping it on a car charger for now and turning off any sleep function when charging. That at least keeps it connected until I make a call. It's almost still not worth using with having to reconnect hands free. Maybe if a hands free quick connect shortcut could be created?
This is all really ridiculous that a phone with this kind of tech can't auto pair and be ready for a call. My LG Chocolate had absolutely no problems with the Kenwood. As soon as the Kenwood finished booting the LG would auto connect and be ready for a call.
I thought I found a workaround at
http://forum.xda-developers.com/sho...ghlight=bluetooth+connection+drops+phone+call
But, once installed an trying to run BT Restart I get an error saying that I need .net compact framework (version 1 or 2) installed. Not sure what to do now, cant seem to find a cab for this.
I've used this package from another post on the forum. It has many useful apps including the latest version of .net compact framework.
http://www.tyguy.net/_xchg/PPC/@essentials.rar
Let me know how it turns out!
I will take a look but I have 3.5 already installed. I guess that app needs the older version. Not sure I want to mess with downgrading it.
Not Kenwood
Hey Guys,
I drive a Jag XK8 and it has the same issues you are mentioning with your Kenwood, but its an Alpine unit, it drops calls, and after the first call connects the second call rings on the stereo but you can only answer on the handset.
I also recently had a new Jag XF for a week. It had a full integration to the phone. It also only showed the battery status when the phone first connected then the battery showed empty. It would drop bluetooth connections constantly on some days (every 90secs) and then somedays it would keep the bluetooth connected without issue. Very unreliable.
The reason I bring this up, is just to let you know these issues are not limited to the Kenwood.
Dave
Just an FYI. I have found it easier to just go into setup in the Kenwood and reconnect the bluetooth from there when the phone disconnects. It's under Setup/Bluetooth/Set, then just click on the device and hit connect. It seems easier than fiddling with the phone while your driving.
I have been having intermittent issues with Bluetooth audio cutting out on my Captivate while I am on a phone call over Bluetooth. I believe the problem stems from Samsung's inability to do anything right and their implementation of Bluetooth 3.0. A new feature of Bluetooth 3.0 is the ability for a Bluetooth connection to transfer data over Wifi if both Bluetooth devices support 3.0 and have compatible Wifi chips. Samsung implemented this poorly, not a real surprise, and now Wifi is causing the Bluetooth data transfers to be spotty causing streaming data, voice calls or audio streaming, to to be adversely affected.
I was able to finally narrow down the problem. I received a phone call yesterday on my cell phone and I picked up the call on my Bluetooth enabled home phone. The call sounded horrible, noise and the other caller was cutting out, but not enough that I couldn't understand the other person, so I continued the call. The person on the other end did not seem to have any idea that the call sounded so badly, so it seemed to be something limited to my end. During the call, I went over to my Captivate and turned off Wifi. Instantly, the call cleared up and the quality was good to excellent.
I use Wifi all of the time especially at home, so I wasn't going to be turning off Wifi all of the time, so I needed a workaround. Using an App called Setting Profiles, I am able to have Wifi automatically turn off anytime I am on a call and then when the call is completed it turns Wifi back on. What's even better is that the app will note the state of Wifi before a call, so if Wifi is already off before a call, it will not turn Wifi on when the call is ended. The Tasker app will allow you to do the same thing, so if you already have Tasker you won't need Setting Profiles.
This tip will probably only work on the Samsung Galaxy S line because these phones use Bluetooth 3.0, where most Android phones use 2.1 or earlier and do not support Bluetooth file transfers over Wifi. I have only experienced it on the Captivate so I can't say if it will work for any other Galaxy S phone.
Since both wi-fi and BT uses the same 2.4Ghz frequency, interference maybe anticipated although new BT hardwares are pretty good at reduce such interferences.
Did you try change your wi-fi router frequency/channel so that it won't interfere with your BT? Try that so that you may not need to turn off wi-fi on the phone at all.
I have had the issue occur in my car while not near any Wifi router. Also, the router was still on when the call quality improved. It's not like the radio waves from the router and three other Wifi devices in my house disappeared around my phone just because I turned off the Wifi on my phone.

Thanks for the tip
While driving bluetooth stops or some time lag voice if wifi is on. same issue noticed without wifi enable also but very less.
It seems whenever wifi changes to different network or connects or disconnects bluetooth is loosing or lagging voice.
Where as if i put it on speaker i can hear sound from speaker. I tried 5-6 different bluetooth and having same issue. i got replacement of phone also but same issue with new phone also. I could verify with older phone and it seems issue is only with Idol 3. Is any one else facing similar issue?
I tested this using a Bluetooth headset, and I am unable to replicate it. Turning WiFi on and off has no noticeable effect on playback via a the Bluetooth headset. Unfortunately , I have no way to test this while driving .

This issue is mainly happening while driving. It seems like while driving phone tries to goes from LTE to different modes and same with wifi as it tries to connect to different wifi. In this process it starts to lags voice on bluetooth and in few cases sound get disconnected.
Are you listening to music on your phone or streaming?
I haven't had any issues while driving using both Google music and slacker. Those are the only two streaming apps i use tho. I leave my Wi-Fi on all day. My deck is a Bluetooth pioneer unit, though the model number escapes me at the moment. I'm on T-Mobile BTW.
I don't drive anymore but I stream Rhapsody overnight onto my BT speakers and it never has conked out on me yet. There was one time I did lose the BT connection to the speakers before I did the factory reset but no issues with the BT since.
Issue is not with listenting music, it is during call through bluetooth while driving and having wifi and bluetooth both on.
OK I'll test that later on today. How often/with what frequency does it happen to you?

Almost 2 out of 3 attempts i am having this issue. even now in home i started call on bluetooth when wifi was off, then just put wifi one during call and voice from bluetooth started to get blurry and then other party could not hear me. and i had to disable wifi and then disable bluetooth and then on bluetooth again in phone.
Seems like issue is happening when phone is trying to connect to wifi and call is on bluetooth...

I do not have Netflix - but I tested with HBO Go - and YouTube - with airplane mode , WiFi and Bluetooth - And I am not seeing any audio lag - or audio interruption when switching from speakers to Bluetooth mid session. I am using Arctic P253BT headphones.
Alright I did a call today. It was only 5 minutes long but didn't notice anything. I'll try doing what you did starting a call in my driveway and turn WiFi on/off repeatedly at various time intervals.
I got replacement, but i can still see the issue with new phone also...

Sorry, my testing is put on hold as I had to send the device in to get a new screen (cracked). I couldn't get it done before because my wife kept stealing my car
I'm having kinda' the same problem. The thing is everytime I connect/disconnect there's a general lag in the phone! after one minute or so, it starts working ok

It's possible the bluetooth is unreliable because the phone gets busy as you indicated...I posted a couple of apps in the idol 3 apps section that help reduce lag and may help this...
Something I've done has made my bluetooth totally unreliable....whether linked to car or home phone system I can answer...talk for a few seconds and then it transfers the call back to the cell instead of the bluetooth device. I'll have to go back through my backups and find a version that doesn't do this.
I have demonstrated the same effect with my bt device (lg). When switching wifi networks bt microphone stop receiving so other party cannot hear me and the audio begins to break up and lag. I can switch off bt then back on and am fine till next wifi switchover. I was hoping the update from Alcatel would address this, was not the case. ;(
I also had the same kind of issue while listening music in car using Bluetooth, strangely it is happening when the WiFi try to connect to open WiFi available. And when that open WiFi is not able give internet accesses, then the phone just get stuck for some time. I have these issues frequently I need to restart my phone
I just purchase Alcatel Onetouch Idol 3 and and am having similar problem. I had a Plantronics M50 connected and people complained that I was breaking up and they couldn't hear me and it happened on my end sometimes too. When I'm calling someone, the ring will be normal at the beginning of the ring and then it will fad out at the end of the ring. Store rep told me this was normal. Has never done it with any of my other phones. Bought another bluetooth to try to determine if it was the bluetooth or the phone. Bought the Plantronics E50 and the same thing happens. Alcatel says it's the bluetooth and Plantronics says it's the phone. Betty at Alcatel also says the Plantronics bluetooth are not compatible with the Alcatel, however, the store sells the Plantronics Marque II to use with the Alcatel. Anyone have any suggestions or having the same problem?
I'm having the problem in car on bluetooth where the caller sounds like they are underwater and garbled and I'm told I do too. It comes and goes, very frustrating. I tested another Android and no problem.

There's a problem with the phone. It happened after the last Android update. My bluetooth was fine until marshmallow. It's so bad I went back to my Galaxy S4. I loved the Idol for just about everything, but horrible bluetooth. People can't hear you, it's a deal breaker.
Anyone else finding that the Bluetooth audio can be a bit hit and miss, the audio has just fully cut out on me, but it displays as if it's still connected and playing via the headphones. I had no audio through either headphones, switching BT off and on, and rebooting headsets didn't solve it. Rebooting the phone brought the audio back, phew!
Out of the two headsets I have, My cheap Sony WI-C310's seem to work better, Using my jabra halo smart headset, it doesn't seem to connect media audio if it's also allowed to handle calls. I have to toggle calls off and just media to use Spotify with the headset (this could just be that headset being weird, think it got discontinued for not being great)
Anyone else having BT audio issues?
I've got a Huawei smart band 6 connected at the same time if that's a factor, it wasn't a problem on my original Nord though.
I have been facing the same issue for a while now, it's pretty random. There are times where it works perfectly and other times it either doesn't connect at all, or has a very weird delay, where it's fine in the beginning of say a video and gets a delay mid way through it. There are times where it only connects to one earphone, just issues all around. Also am using the oneplus buds z2, so honestly would expect it to work flawlessly with a oneplus device. The earphones work fine with other devices.
I've been getting random drop outs.
Both with connectivity with my car infotainment system and my cycle computer.
When I had my OP7Pro, never experienced anything of the sort when connected to these two same devices.
I've also tried enabling Bluetooth Gabeldorsche in the developer settings, and that didn't make a difference.
Will try changing the Bluetooth AVRCP version to see if that improves anything (currently set to the default of 1.5).
Has anyone else played with those settings and tested the impact?
Tested with 3-4 Bluetooth devices and no drop outs.
I notice that when I put the device in aereo mode the Bluetooth remain active, but in the latest days this problem doesn't happen anymore, maybe was a bug of the first fw, and after last update they have fixed?
