wifi killing bluetooth?

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

Bluetooth audio madness - am I asking for too much?

Hi all,
I've just bought my first HTC unit ever (Kaiser), which is also my first Windows Mobile Phone (I used PocketPCs since 2001 but with no integrated phone so far), and it seems to have a lot of issues in the areas of "regular phone" functionality.
However, the one that is really freaking me out so far is the whole "Bluetooth audio" area. I'm just wondering whether I would ever be able to get what I want or am I asking too much.
I have 3 Bluetooth audio devices, all of them are dual Headset/Headphone ones: in-car fixed Motorola T605, Jabra BT8010 and Plantronics 590. Now, naturally, I want to use the T605 in the car, Jabra for phone calls only throughout the day and for music occasionally, and Plantronics when I'm in the gym, for both music and occasional incoming phone calls.
I had all this working flawlessly with my SonyEricsson K800i phone: each device connected to the phone automatically when powered up and automatically took over both Headset and Headphone functions. The only minor problem was reconnecting Jabra when stepping out of the car, which required only a short tap on the button.
Now, with Kaiser, things are much more complicated. When a device (any of them) is connected to the phone, both as Headset and Headphones, it works mostly OK, although sometimes there is a problem of sound not coming through the device when an incoming call was answered while playing music. The music is suspended OK, but the sound comes from the phone speaker instead of the respective Bluetooth device. This happens from time to time, not always.
But the biggest problem is the initial connection of a device after another one has already been connected. When I enter my car and fire up the engine, I want the T605 to automatically connect to the phone even if Jabra has already been connected. This I was unable to achieve. Instead, I have to manually disconnect Jabra (by powering it off or temporarily powering off Bluetooth on the phone) and then manually connect the phone with the T605, for both Headset and Wireless Music (two actions required!). Now, for me, this is unacceptable.
Moreover, when I arrive to a destination and want to step out of the car, I have to manually reconnect my Jabra to the Kaiser, again, through the phone’s Bluetooth settings as described above. A short tap on Jabra’s button no longer works for this purpose, in opposite to SE K800i.
Making the long story short, this is completely unacceptable behavior for me, and I haven’t found so far a way to make it the way I need it.
Any advices?

Have you tried the Bluetooth fix on HTC's website?
Asking is easy, searching is hard work for some people it seems. No offence..

I'm using Schap's ROM which is supposed to have this fix built-in.

Ahh. didn't see that in your first post..
I think you are suffering the same prob as many. Every time a BT device comes out, it never seems to work with what we had before. BT protocols are NOT fixed (The IEEE STILL have not fully implemented a specific proto!), they change faster than we change our devices.
As I said before (without meaning any offence) search the whole forum, many threads have been out on this subject and some advice/fixes or equipment references are out there.

Well, I did search these forums and haven't seen someone referring to the same kind of problems I'm having.
Now, regarding your comment about variety of BT devices... I don't buy that. My SE K800i is 1 year old and works perfectly with this combination of devices.
I have pretty extensive experience with Broadcom/Widcomm BT stack on PC and older models of PocketPC (the one I have is IPAQ 5555) and I suspect these foes are direct derivatives from the fact Kaiser uses MS BT stack, which is much inferior. However, it seems nobody was able to make Broadcom/Widcomm stack work on Kaiser so far...

OK, I'm sorry if you don't. I only tried to help. Seem's you've asked a question and have already formed an opinion to it!!!
I have personal experience of Sony's proprietory connection limitations.
My BT works fine on all my devices....will leave you to others.

Looks like I found a partial solution which makes my life almost perfect...
It seems the real problem is taking over Kaiser from a previously connected device. So, if I switch my Jabra off several seconds before I fire up my car's engine, my T605 is able to connect to it. Same goes the other way around, I can turn off the car engine and then fire up the Jabra several seconds later. In this case all is good.
Looks like the MS BT stack is still ill-implemented though, as, for example, when in active Wireless Music BT connection, the device is unable to discover any other Bluetooth devices or to connect to other device's BT serial interface, which makes using external GPS devices difficult.
This could be a problem for me since my car (Citroen C5) has special anti-radiation coating on its windshield which quite effectively screens the satellite signals. Therefore I came up with a solution of having a BT GPS device permanently located in the car (actually, in the driver's seat back pocket) hardwired to the mains as well as to an external GPS antenna. This setup is effectively beating both reception and start-up time problems.
With Kaiser’s limitation on simultaneous BT connections I’m unable to use this setup anymore. Yes, I could bypass using an additional GPS device by connecting the external antenna to Kaiser’s internal GPS, but this looks like a cumbersome solution as I couldn’t find a Kaiser-compatible mounting with a socket for hardwiring an external GPS antenna.
Luckily for me, I still have my old IPAQ loaded with GPS software which I prefer to use for navigation anyway thanks to its significantly bigger screen

Glad to here you have a resolution (albeit a partial one).
Just one thing, why would you want to connect to an external BT GPS at the same time as your car kit? Can't you get a good enough signal on the internal GPS or is there another reason?

Yes, that's what I wrote in my post above. This antiradiation coating is a real satellite signal killer...
But, IMO, Kaiser's screen is too small for in-car navigation anyway, so having a dedicated unit is always a plus

Sorry, blind AND stupid!
Yes I agree the screen is too small for general use. I have a dedicated GPS in the car and only use the TyTnII as a temporary routefinder whenever needed.

WiFi disables or crackles Bluetooth and kills VoIP

Weird issue with new HTC ROM (version no. below) - anyone else got it or know a fix?:
If I make a BT call with WiFi on, the BT crackles and flits every second.
If I turn off WiFi it is perfect.
If I set WiFi to 'Best Performance', all BT devices are lost and disconnect.
If I set it to 'Best Battery' or the middle setting, BT devices reconnect.
VoIP calls via Bluetooth now crackle themselves to death, because such calls use BOTH Bluetooth AND WiFI simultaneously - shock horror!

(Updated post above with VoIP issue)

i was having the same exact problem, took me couple days to realize it was the wifi. Only thing ive been able to do(motorolla s99 stereo) is make sure my headset is FULLY charged before pairing. And (no fix here) i shut the wifi off when im in the field. There is a bug there for sure. Is it just too much for the phone to track the 3g, wifi, and duplex on the BT?

I have exactly the same problem. BT works great with my headset (Plantronics 8XX) and has good range and is very clear. My WiFi works great and has a good range BUT if I have both turned on my BT is useless. BT devices are not visible more that 30cm away and there is a major crackle even at less than 30cm. Took me a while to work out why my BT headset would not pair with my TyTn II and Plantronics could not help. Used to work with my previous TyTn II OK, so I did a hard reset and then BT paired fine. Then I realised it was simply that hard reset turned off WiFi so I wasted my time doing hard reset when turning off WiFi was solution.
I called HTC and they can't or won't help but they did say they would log it and look into it (do we believe them? ;0).
The BIG PROBLEM for me is using SIP/VoIP as this uses WiFi of course but because of front speaker issues on TyTn II it is very hard to use without a headset and sound it just not good enough most times to use on my unit. So BT headset is the answer but can't work due to this WiFi/BT issue.
I am going to try flashing various different radios this afternoon as some members said this may help but from what I have read on this forum it does not solve problem completely.
If not then it's back to my wired headset and looking like an 80's teenager when I am using VoIP.
Also I wanted to install Navizon and earn points driving around with my WiFi on but this would mean no BT headset so I can't do this.
This really is an annoying bug.
If anyone has a fix or has found something searching the forums that my searches have not found then pls let me know.
Thanks.

A2DP Bluetooth Audio interrupts

Hi Guys,
i have this problem for a long time and didn't find anything about it in web or in xda forums.
I have a HTC Dream + HBH-IS 800 Sony Ericsson Headset.
When i listen to music via A2DP the connection is not very stable...
the connection interrupts very often for about 2 or 3 seconds, then works for about 3 seconds.
This only happens when i am outside, not in buildings. I this the reason is because of interferences. The connection gets better when i move the G1 into a specific orientation (upper side up) and don't turn my head to the right
On my old Windows mobile phone i played around with bitpool (=ratio between quality and connection stability by constant bitrate) settings... is there a possibility to get the connection more stable, when playing around with this setting?!
How can this setting be changed on android?
Further information:
-ROM Cyanogen 4.2.5 but same problem on stock ROM
-HTC Dream has been replaced one by a new device -> same problem
-Headset was never exchanged, but worked perfectly on my old Touch Pro with WM 6.1
Thanks for your help

There is a known issue on the Bluetooth stack and is suppose to be fixed in the Elclair 2.0 fix, the temporary work around is to first pair and connect then disconnect and reconnect it again i'm having to do that several times a day when i use my RocketFish bluetooth stereo headset. Hope that helps

thanks for this workaround, will try it tomorrow and will post if it works for me too

hmm, didnt really work for me... no change after pairing disconnecting and connecting again.
i wonder why this only happens outside, not in buildings... another frequencys which interferences maybe?!

Be sure to disable wifi.

Not trying to hi-jack your thread. If you want me to open another i will. However this is a BT question as well.
my G1 is set to connect to my stereo in my car. Pioneer BT head unit. I find that i have to manually tell it to connect every time i get in the car. When i had a blackberry before it would just connect every time on its own without me doing anything once i made the initial connection.
Any ideas?
thanks.

Worked on Dell Streak A1.6

I have Dell BH200 headset as well, and I have the same exact problem its like the audio stutters but when I first connect it its more stutter than music so you can barely even understand the music until after 30secs when it starts to normal out.
ATM im runnning Stock 1.6 for G1, im going to try Cyanogenmod 6.0 tomorrow and see if anything changes.
but everyday I go back and forth with my laptop and phone since my headphones run for atleast 3-4 days.

wow, finally someone having the same problem.
and even the same description of the connection issues.
I recently bought a orange SanFran and, as the device is fairly cheap, a nokia bh-504 along with it.
The connection isnt stable even when I put it in my breast pocket.
As soon as I move my head to the right, the streaming stops. Completely.
I can easily stop the music when holding my hand in front of the right earpiece.
so i will try the disconnect / connect again "workaround", but I don't think that will help.
I paired the same headset with my gf's netbook and I could walk through the whole apartment and the signal was stable even through up to 4 walls.
so no one here knows how to tweak BT settings in android?

HTC One Terrible Bluetooth range .....

Friends ...... , HTC One it seems has a terrible Bluetooth range ....... I have a Logitech BoomBox (Bluetooth spks) and a Belkin Bluetooth receiver connected to my AVR. In both the cases, when connected to my HTC One it looses audio in just couple of feets. Specially with belkin receiver. But when I tested the same with my iPhone 4, it works perfectly, till the Bluetooth's designated range of 30 feet (10 meters) ... with both Belkin and Logitech ....
so it has something to do with HTC One's Bluetooth.
People with HTC One and having any Bluetooth audio device, please test this and report if you are also facing the same issue, Or is there something that I can try to increase the range. Its pathetic, 2-3 feets at the max. I am bitterly disappointed with this ..........
Regards.
Sammy

I think that Android 4.1 had a BT flaw that was fixed in 4.2.

so this means its more of an android issue than HTC One........ any alternatives to improve this, till we have an 4.2 update

I was using bt audio yesterday and it was horrible. I did some googling, try turning off wifi before you connect to the speakers, it solved my trouble straight away. I found if the music was playing when I turned wifi back on it would still be ok. Might help?

Jiggle .... my friend, you made the day for me, how so ever strange may it seem, it did work .... ..... I switched of my wifi and then connected Bluetooth to Belkin receiver and vola!! :victory:... no drop outs and was able to use BT at full 30 feets, and then if I switch on the wifi later all is well.
Strange, if wifi is working before I connect BT, it drops and is very uneven ......... must be some bug, but anyway, solution is not as irritating as one might expect.
Thanks again Jiggle, for you input, saved me a great disappointment.

whew you had me in a panic here. (o; I'm still a little traumatized from my asus T201 wireless issues.

The Wifi/bluetooth issue is a drawback of the aluminum body design of the One. Bluetooth shares an antenna with wifi transmit. I believe wifi receive shouldn't interrupt bt though.

Then there should also be a problem if I switch on wifi after I connect BT. ,... in which case it works. It only creates a problem, if the wifi is first on and then I connect BT. ...... which is strange

Just for information. I had 3 htc, desire hd, sensation, onex and ALL had problem with bluetooth, weak signal, using a headset with the phone in my pocket already failed. I now have a note2 and this problem does not occur, being used in the same situation. So ....

My m7 (TrickDroid, elementalX 0.11 default overclocking and undervolting) is having the BT issue whenever wifi is on, regardless of whether I connect the BT device while wifi is off, and regardless of whether audio is playing when the wifi is turned back on. In other words, on my device, BT really really sucks if wifi is connected, period. Any suggestions other than not to use wifi if I want to use BT?
Update: My router (Netgear wnr2000v3) seems to use 2.4 Ghz channels. Any thoughts about whether swapping the router with a dual-band or 5 Ghz channel router would work around this issue?

I did pick up a new dual-band router and set up the phone to connect only on the 5Ghz band, and it worked! No more bluetooth issues at home. So if you run into this issue, a temporary workaround until (hopefully) HTC/Google provide a fix is to avoid the 2.4Ghz band.

Strangely enough, my Bluetooth range keeps decreasing with each software update. When I first bought this thing, I was generally impressed with how far I could walk from my BT speakers. Not as good as my evo 4g or 3d, but decent. Better than my gs3 and gn2.
Now I tend to make it about 5 feet or so with minor cut-outs while using apt-x. If I put my hand between the signal at 10ft, I can stop it completely. If I touch the upper-right of my phone with my thumb as I hold it in my right hand, I can kill the signal as well. Very much an antennagate going on here just like the iPhone 4.
