[Q] Bluetooth connection dropping during phone calls - Desire HD Q&A, Help & Troubleshooting

Hi Everybody,
I am having a strange problem:
I have several BT headsets connected to my phone. There is a JABRA Halo at home, a JABRA PRO at work and a CarKit in my car.
On every device I get connection drops on phone calls. I initiate the phone call and in the first 10 seconds everything is ok. Then the other party cannot hear me any longer.
If I switch to speaker and back to BT everything is fine for the rest of the phone call and in a time after the call for all further phone calls (it think if the phone is not going to standby in the meantime).
This happens with all ROMs I used. Original HTC, LeeDroid, ARHD, Beta 2.16 ROM. It happens also with all BT devices.
This is very annoying as I use my phone for business.
Does anybody have had a similar issue? Any solution?
Regards Frank

problem using bluetooth headset on desire

Hi all, I have a new Bluetooth headset h680 which I have paired with the desire, its connected and when on a call the person on the other end can hear me but I cannot hear them....anyone have a similar problem?
No, but only tested Plantronics 975. which works fine.
I Have a problem with the bluetooth as well. The connection and pairing are OK but there is no sound coming out of the headset.
I've google it and it seems there is a general problem with the bluetooth audio.
I also have a bluetooth problem.
I paires with my car kit (jvc kd-r711) and after a few seconds i get a error saying "headset disconnected"
I've read similair problems since the froyo update. Anyone else have the same problems?
@johnsten
Yes, I have the same problems with my Volkswagen Golf 6 navi!
At first, the phone connects just fine. No problems at all. Made several calls, phone book is synced automatically. All fine..
But then after some time it gets bugged. When I tart my car, and the systems sais.. phone connected. My desire sais "headset connected", and after some seconds it says "headset disconnected". The Bluetooth connection remains active, but the phone is not in "headset" mode.
The only thing that really seems to fix this problem is a full system swipe, but then I lose all by programs and Angry birds savegames
I really want to get rid of this problem. Any ideas?
Grtz, Ron
similar to jah, only tested the plantronics 975, never had issues
also working well with my Jabra Extreme so far
no problems with Nokia BH-503 and SE MW600
No problem with my SE MW600 either, for 340 SEK (36€) it has everything I need: volume, back, play-pause, forward and mic
No problem with either my JVC-901 car head unit or Sony Ericcson HBH-980 stereo headset
ford focus bluetooth headset issue
Hi there, I have a problem with the desire and Bluetooth with my Ford focus.
It pairs fine, but looses connection after about 45 seconds. If you check a task manager you see the Bluetooth process at very high CPU after the disconnect, for a number if minutes.
If you make a call before the Bluetooth drops out it remains connected for the duration of the call !
Tried disabling WiFi etc, makes no difference.
Any ideas?

I had just the exact problem no problems any more though after this fix I dont know if it was a bad rom flash that screwed something up for me but BT works great now
I have the same problem, bluetooth paired but can not hear anything. I tried over 10 different, but it does not help. Can anyone solve this problem?
I'm having a similar problem with my car stereo & HTC Desire bluetooth connection.
I have a Silvercrest stereo with blutooth which worked with my provious Nokia & Blackberry but cannot get it to work with my Desire (2.2 Froyo)
The 2 devices will pair but when I try to make a call or receive a call the devices disconnect.
I am not at all savvy about flashing ROM's or anything so as simple a resolution as possible please...(& no, changing my car radio is not an option )
Any info is greatly appreciated as I spend a lot of time in the car & need the hands free

I have a Pioneer 7100bt car radio and a Desire with Leedroid 2.2f and i does the same.
Does somebody know a solution??
I too have a H680 and like you, callers can hear me however, I can hear them but very quietly even with volume full up.
I also have a Jawbone 2 where I can hear callers but they cannot hear me very well.
The Jawbone 2 was fine with previous handsets.
No solution though, sorry.

Problem with Windows Mobile and Bluetooth Headset Playing Audio

Hello guys,
I just got a Sony bluetooth headset and I am trying to use it with my HTC TYTN II. At first I paired the phone and the headset and I was able to listen to music and talk through the headset, all perfect. When I was listening to music, the bluetooth icon on my phone represented a music note and a headset over it.
When I turn the headset off once and then on again, it connects automatically with the phone but in some other mode. The bluetooth icon now represents the bluetooth sign with a headset over it. Now when I listen to some music, it comes from the speaker of the phone, not from the bluetooth headset. Talking through it is not a problem.
If I pair the phone and the headset again, it works just fine (showing again the music note) but once I turn the headset off and on again, I lose the music mode.
Does anyone know how to fix that? Thanks in advance.
I fixed the issue by installing AutoA2DP (found in this forum).
I've had a similar problem on my Tilt. I originally posted the following on the ROM thread. Since then, I have found that the AutoA2DP has not fixed the problem. I still have this issue about 70% of the time, and sometimes I can't get the bluetooth to work at all, not even after a soft reset. Sometimes it seems as if the bluetooth has no power, the phone can't communicate with the headset except when within a few inches of one another. Then it magically seems to resolve itself. Anyway here's my original post from the ROM thread.
The other day I installed an app on my phone called Schaps Network Plugin, which allows you to map network drives to the phone the same way you can do with a desktop. It allows me to access the home network directly via my wifi. It was something I needed and it seemed to work great, for a day. The next day my bluetooth headset would not connect. Long story only slightly shorter, it seems the problem was with the headset connecting via A2DP and doing so automatically. This always worked just fine in the past. Suddenly it wouldn't work. I tried a ton of things including a "fresh" install of everything and formatting my memory card to start with nothing on it. I flashed the original rom and then flashed this rom. I did hard resets each time. Did this twice. Even tried the bluetooth in the oem rom to see if I still got the problem. I did, and it is still with me. I can manually get the headset to connect via A2DP using the bluetooth settings, though even then it may take reconnecting several times to get it to work. However, when I turn the headset off and then on again, the A2DP does not reconnect, just the hands free. But the sound is not routed through the phone's speaker either, at that point. In fact you often get no sound at all, nothing via the headset or the speaker. OTOH, if you activate Voice Command, the headset does work while Voice command is running. After it shuts off, you are back to no sound. It seems as if the hands free works fine, but the audio gets partly routed to A2DP but does not connect to the headset. If I reset the phone, the headset connects correctly and efverything works until I turn the headset off again. Also if I pair the headset again, everything works correctly until I turn the headset off. Though pairing is not as trouble free as it used to be either. Sometimes it will not pair up wihtout repeated attempts. I did find this program, AutoA2DP which has patched the problem. It detects when a paired bluetooth device connects, and forces a connection via A2DP as well. But I never had this issue in the past, and my wife's phone still has no problem. I am not sure the Schaps Network plugin had anything to do with it, other than the timing. Seems odd to me that the bluetooth stack would suddenly develop issues that persist even after two fresh flashes of the rom. Any ideas, suggesitons, etc.? This is really bugging me, and although the patch seems to be working, the phone is still not acting "right." In the past, and on my wife's phone, if a bluetooth headset is turned on, it automatically connects, and all sounds, including the system sounds, are routed through the headset. Now, sometimes they are, and sometimes they aren't.

[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.
Kev
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 ?
- otherwise I don't know when they'll fix this..

Anyone with this specific BT issue?

Phone has been solid since a week ago when I got it. Works like a champ, BT audio in the car works(2016 Colorado with MyLink NAV system)... Works really well with Android Auto... phone call quality through the car was perfect... Updated to 3.2.1 yesterday or the day before, still works great, no issues...
Today I am on a couple calls in the car, no problem. Hang up on one call, try to make another about 10 min later, says I am connected to the person, but I cannot hear them and they cannot hear me. Try a few times, same issue. Try calling other people, same issue.
Reboot the phone, same issue. Stop and turn off the car for a minute, same issue. I can talk to them on speakerphone, but no audio goes in or out over the phone via BT or Android Auto. Other sounds like music and everything work fine. Everything works fine in fact, except any audio associated with the phone.
Visual Voicemail, won't play through the car, only the phone speaker...
I reboot the phone and car again, same problem.
I delete the BT connection in the car and the phone and re-pair, same problem...
I am gonna go to a friend's house to try his phone, but has anyone ever heard of this? It was literally working fine for a week up to today, I didn't shut the car off between calls... It was working, I hung up on the call, tried to make another one a few minutes later and now nothing works...
Help!
