Hi,
i notice this problem. when i on my bluetooth and Wi-fi. the system thens to lag and i cant connect to my headset. even if it is connected. it will disconnect from time to time.
this problem does not happen when wi-fi is off.
can anyone help
thanks
I believe this is because bt and wifi operate on very close frequency. Having said that I stream MP3 from my tversity server to my kaiser whilst listening to it using my bluetooth headset. Sometimes there is the odd blip but mainly it works fine.
Maybe the ROM you are using isn't helping. I use Dutty's v4. You might also want to try schaps advanced config as there are some bluetooth setting tweaks you can apply with this.
I sync by bluetooth while I update my RSS reader by wifi without problems. Haven't tried a BT headset, though...

Hi foobar1977,
yup both operate at 2.4G bandwidth. but they dont really cross each other path. i am using iclip headset and i am not sure i am using what rom.
sorry could u point me to schaps advanced config ????

hrm this isnt good - it would appear bluetooth stops working when wifi is enabled - was listening to an mp3 on bt stereo headphones and enabled wifi and it killed the conn - not only that it seems i cant use any form of bt device if wifi is enabled (not even connected) on the device - wtf?
is anyone else experiencing this?
No, I use Jawbone BT headset with all sounds out BT using BTaudio.exe then start WiFi on home LAN and watch streaming video from Slingbox.
this was the case with the titan...
eric b
do i have a faulty unit?
i don't think so. in the titan, the bluetooth and wifi antennae were the same actual unit.
eric b
you sure? remE says both work at the same time just fine for him :s
to me it seems as thought ewifi signal is overpowering the bluetooth or smt - does the bluetooth freq lie in the wifi freq range or smt? is there any way they could overlap?
both work if i have only one on at a time - can anyone confirm either way if both work at the same time for them and what equipment youre using?
I'm doing it as a type this. I'm watching 30fps video streaming at 300k over WiFi and listening to it thru a Jawbone BT headset. For sure this works fine.
I have a Hermes and it would not do this well at all, it would allow BT and 3G video streaming but not WiFi. Kaiser can handle it.
maybe you could try a differet BT headset, maybe yours suffers from inteference ( i don't know the frequencies of BT and WiFi but WiFI could be killing the connection because your headset jamms)
BT and WiFi are both spread specktrum radios operating at 2.4ghz. They are designed to co-exist and do so on Kaiser. Maybe there is a difference with Stereo vs Mono headsets, they do use different BT profiles. If I get a chance I'll try a stereo set and report back.
thanks guys - i need to make sure my unit is duff before i ssend it back for a replacement ;(
looks like my unit is gonna go back - i called htc and they said they havent heard of this issue before and are 'escalating it' - it seems that superetrader wont give me an RMA for my unit until htc have given me a reference number - is this normal procedure? seems a bit odd to me
i tested my unit some more at work today with a whole host of different bluetooth and wifi gadgets and the problem is consistently reproducable
gutted
I found a problem with my kaiser phone last night. The problem is that if I listening to music with my bluetooth headset I am not able to connect to my WiFi at the same time. This problem is specific to A2DP because my headset can be connected to my phone and I can not browse the web with WiFi. Has anyone seen this problem before? Has there ever been a resolution for it?

I've seen this too -- when using A2DP, the WiFi connection goes down & won't re-establish itself until I turn off A2DP. I haven't found a resolution yet -- not that I'm looking for one as I almost never use A2DP, and when I do, I'm in the car, where WiFi isn't too useful.
See my post here which may be a related problem. I assume you have the same new HTC ROM: http://forum.xda-developers.com/showthread.php?t=396409
I have a similar issue. If I am streaming music, from my HP media server, over wifi and using my Plantronics 590A bluetooh headphones, after each song I am asked to log back onto the network and as each song comes to an end my device starts to search for a network connection. I don't have this issue when I use wired headphones. Clearly there is an issue when both bluetooth and wifi are used at the same time. I don't know if it's hardware or software but I'm not happy about it.

HTC TyTN II (Kaiser/P4550)
Rom ver: 1.82.707.0 WWE
Rom date: 11/03/07
Radio ver: 1.27.15.32
WM 6 Professional
CE OS 5.2.1620 (18125.0.4.2)
It's normal. Without going too technical, WiFi and Bluetooth operate on the same frequencies. They will live together if they're not using too much bandwidth, but if the usage is heavy there will be problems.
A BT stereo headset represents a lot of data to send and thus bandwidth usage, which means the BT will use the spectrum heavily, stepping over the Wifi. Due to the many packet losses the Wifi connection cuts.
Other way around, if Wifi is under heavy load, Bluetooth might drop.
Nothing we can do, that's what happens when you pack 2 radios operating in the same frequency band so close to each other, or even maybe sharing the same antenna which might be the case in today's phones.
It is absolutely NOT normal. The reason I know this is that VoIP over WiFi has been running almost perfectly on my TyTN II for a year, until I installed the latest ROM by HTC which broke it.
I used to get no crackle on Bluetooth calls with WiFi turned on. Now I do.
I used to get great quality VoIP. Now it is beyond unusable.
Simply, their new ROM broke it. BT and WiFi used to live in harmony, until their buggy ROM came out the other day. I think there are many users who know this, and who expect a hotfix soon.
You're talking about calls, I assume using the BT headset profile, while the other people in the thread are using A2DP wireless stereo. They're very different in terms of bandwidth.
On mine the headset with WiFi is also fine, but not A2DP. You're apparently not having the same issue than what is mentione in this thread. Yours might be due to the ROM, but the A2DP thing is more likely to be related to what I explained. I could myself experience it with several ROMS (all WM6, never tried a 6.1).

My old TyTn II worked fine with BT and WiFi on at same time - never a problem. I always had WiFi on at home for emails etc... and always have my BT headset (Plantronics 8XX mono) working as I hate holding phone to my ear and get a lot of calls.
I recently bought another TyTn II and then unlocked it using advice form this forum (many thanks to all BTW!) and installed latest HTC rom and WM6.1 etc... Now I love many aspect of the new ROM but I can't use BT and WiFi at same time.
So from my experience it MUST be the new HTC ROM software issue.
Okay, chalk me up as another victim of this Wireless + A2DP = Crap Reception. I've tried three other Radios and the effect is the same.
I was using a rom I got in about April, and I could stream music from the internet over wireless listening to it on my Pantronics 590A's over bluetooth no issues (other than battery lol). Now with a rom I got this month, I can listen to music over bluetooth no problem, surf using wireless no issue but as soon as you mix them both it's all bad. Also, I need to re-pair my headphones whenever I want A2DP, where previously I could just turn on the headphones and have them connect. Also, no headset icon in the taskbar.
It's not a CPU issue as there's no excess usage when you both have them enabled. Personally I'm going to point the finger at the bluetooth stack here.
As far as I remembered when I first purchased the ATT Tilt with my Plantronic Voyager 855 I WAS able to stream via Wifi (Winamp Remote) and use my bluetooth without a problem. It's when I started to put cooked roms in the Tilt that it stopped working correctly...
Besides, I use a Macbook Pro via Wifi only and I listen to my Itune via my Plantronic Voyager 855 everyday. If it's true about WiFi overloading Bluetooth on the frequency. Why does it work fine on the MBP?
And Finally.... to make my point...
I also have an AT&T Fuze. Works fine there. Matter affact. I'm currently connected via bluetooth to my Fuze with my Voyager 855... turned off 3G/HSPDA on the Fuze. WiFi on the Fuze using Winamp Remote to connect to my PC streaming from there. Explain that....
Has anyone fixed this problem?
I'm experiencing the same problem on my kaiser aka xda stellar. When Wifi is turned on bluetooth A2DP stereo connection is dropped.
i cant find how to get this working on my kaiser.
ive got s2p i heard thats supported

Yes, s2p will work ok with wireless stereo bt devices. I use motorola s705 and t505 a2dp devices. I don't think that the apps need to specifically support a2dp since every multimedia app I have used has worked.
Sometimes the a2dp connection is not established when I want it. Note that both devices also work in modes other than a2dp.
BatteryStatus includes optional tray icons for phone, wifi and BT. The BT icon menu includes an a2dp indicator/on-off switch. Sometimes i use this for the T505 to force the a2dp connection.
A2DPToggle also works. It is a Today plug-in. I read that it is a battery hog but haven't confirmed. If you can't get a2dp working using A2DPToggle then you might want to dig deeper into your phone/rom.
I am using stock WM 6.1 roms from HTC or at&t (official - test) generally without problems but have to muck around sometimes to get a2dp working by either toggling BT on/off on either the handset or BT device.
i want to kno how to use it tho there doesnt seem to be an app for it i tried finding my mates stereo with my bluetooth stock app and it didnt work how do you initiallise a2dp on the stock roms.
Hi,
I was wondering is there a setting that I need or something so that when I have bluetooth on (connected it to my stereo headset) I can surf the web on opera and stuff?
For some reason when I have bluetooth on, I can't connect to the net, using either opera or IE or the weather update. But when I turn off bluetooth the internet works fine again.....
Am I missing a setting or something?
please help
Thanks
PS: I"m using udk r4 rom.
no one have this problem?
sounds intressting ... i know the problem. but bt and GPRS works fine but no WLAN
Stuttering and skipping streaming are very known issues on many jelly bean devices.
The most times when I listen to music in my car, i do this via bluetooth. So it is really annoying me and some day, I will have an accident, while I am fumbling with my HTC One.
I replaced the audio.a2dp.default.so with one of the Nexus 4 (4.2.2) and it just worked well, but only the first time using bluetooth streaming after rebooting the device.
I changed some settings in audio.conf and it still stutters.
But then, i deactived wifi while the device was streaming and all stuttering and skipping was gone.
So... can someone just confirm, whether the a2dp streaming works correctly, when wifi is deactived?
I want to know, whether this is the only point to get this work and I don't want to change my working mess
is nobody interested in this?
I posted this bluetooth issue a while back on this forum, and the issue is corrected by switching off WIFI while using BT. Apparently the new update which is due soon fixes the issue but only one user has confirmed that so far.
Since I use bluetooth streaming on the car mainly, I use Tasker so that when Bluetooth connects, it automatically switches WIFI off (don't need WIFI while driving and saves battery), and when it disconnects it switches it back on. This way the phone just works seamlessly.
Just turning the wifi off and back on again when I connect bluetooth seems to solve this issue for me.
i can confirm - turning wifi on/off fixes it as well for me (until next time I go bluetooth)
I discovered this a couple of weeks ago too. I was about to send it back too. Cant live without podcasts and audible in the car!
I have the problem that i cant even here any sound on my HTC CAR A100 Car Stereo Clip, even if wlan is deactivated With my old sensation everything is okey..

I wonder if this also improves the bitpool value. I'm noticing on my HTC One that bluetooth streaming quality is not very good. From what I've read it has to do with a bitpool value that it set too low, increasing this value is supposed to increase the streaming quality. Highs sound distorted on my phone over BT I can't believe Google/HTC have not addressed this issue.
I have not been able to solve the bluetooth audio streaming issue by turning off WiFi for my car. It works perfectly fine with my Jambox even with WiFi turned on, but in the car, it does not work either way and I'm using software version 1.29.401.13

I'm running 1.29.401.13 too and it looks like it is working nearly perfect for now. I can remember only one time, when it stopped for a second. Mabye the car radio is facing similar problems? Did you try to update the firmware or whatever of you car radio?

I've tried researching how to update the firmware of my car's bluetooth, but have had zero luck there as well. It's a 2009 Acura TSX.

Did you manage to fix the problem with the A100 as mine is exactly the same, works fine on my Sensation but no the HTC One.
have the same problem:
If wifi is ON and bluetooth is ON, eg at streaming youtube over the bluetooth headset, it stutters and has distortions.
If wifi is OFF and stream a video from the sdcard over bluetooth all is fine.
what i find out:
I use the JellyBean from Quarkx for defy.
The build from 7.3.2013 worked
All later builds, with the new wifi driver had this problem.
But its a known bug that JellyBean has a2dp issues, i guess.
This trick, to change audio.a2dp doesnt helped me
I didn't noticed any problem with my phone even when the wifi ON, I'm using the latest radio "4A.16.3250.24_10.38.1150.03L" found in this post: http://forum.xda-developers.com/showthread.php?t=2245615
I don't know if it can help..
