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

Bluetooth Stereo Headset and WiFi Problem

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.

Bluetooth range drops to inches with wifi enabled

I dont know how long this has been happining because up to 2 days ago I dident use any bluetooth devices with my phone but I just found out yesterday I was having a problem and after hours of searching and narrowing the problem down I finnaly found that enabling wifi caused my bluetooth range to drop to just a cople inches.
The reason I need wifi is that I dont get anything past "E" were I live and thats not vary good for orb and streaming Movies and TV
The reason I started using Bluetooth is I bought a hands free headset and a BT Gamepad, both of there ranges are 1-2 inches but jump to the correct range when wifi is off.

Someone please correct me if I'm wrong, but doesn't the bluetooth and wifi probably operate off the same sytem in the kaiser?

If I had to guess, it would have something to with your battery. If you have a weak phone signal, your battery has to work harder to keep the call up. Just my guess

Thats another thing to try, try keeping the phone plugged in while you do this and see if the results vary from not having it plugged in.

I actually saw it to vary from ROM to ROM. On XDA Live 2.0, i could never use both simeltaneously. If i turned wifi on, my headset would disconnect. After I made my ROM, i had no problems whatsoever with both coexisting.

It's normal. Both interfaces use the same frequency band and must share it. When one uses a lot of the available bandwidth, the other is likely to be thrown off. Now if people report different behavior between ROMs it might be stuff like the prioritization between the 2 being different, or simply low-level settings like the number of retries in case of failed transmissions (as many of those will occur when both interfaces are used simultaneously) before a packet is dropped/connection is lost.
An example of the other way, if I use my stereo handset to listen to music (bandwidth-intensive), the Wifi will disconnect even if I'm 2m away from the router.

Bluetooth Issue

So I paired the One with my QED uPlay at home and I'm having issues. The phone has to literally be 30cm away from the receiver or the audio will start getting distorted until it eventually cuts off. I have two uPlays, issue exists on both so its not tbe receiver. Also my iPhone 4s has no issues either. I was hoping the One had better audio than the iPhone since it has aptx, but its quite the opposite. Has anyone tried bluetooth music streaming? Is it just a faulty phone?

Bluetooth and Wi-Fi both use the 2.4GHz channel. Asus had issues with the Prime because of its all-aluminum design where they had to greatly amplify the Wi-Fi signal and use diversity antennas to get through it. HTC uses the latter on the One. When used together, the Wi-Fi signal can overpower and interfere with the BT signal. Try turning off Wi-Fi and see if your connection quality changes. You're the first one to mention a BT issue so it could be unique to your device. Time will tell.

I have had a problem with bt connecting to my car (audi a1) I can hear the call but the other end cannot hear me. Going to delete connection and try again tomorrow.

Thanks for the replies. I switched off WIFI, re-paired the device and bluetooth started working perfectly, so it makes sense it was interference. Strange thing is I turned WIFI back on and bluetooth was still working fine. I'll do further tests in my car tomorrow see how it goes. If I'm not convinced I'll just get the phone replaced.

I have also had issues with bluetooth paired to my hands free car kit. Issues have surfaced when streaming music and also when making audio calls via bluetooth.
Sent from my HTC One using xda premium

The One X had a similar issue:
http://forum.xda-developers.com/showthread.php?t=1688538
It could be that when I was first trying the WIFI antenna was stuck on high power, which caused the interference, but when I reset the WIFI it reduced its power and no longer interfered with the BT. I have changed the WIFI at home to run at 5 GHZ, but work still runs on 2.4.

I am running 1.28.401.7. How did you update to the latest ROM? I don't want to unlock my bootloader in case I need to return it.
Did you used to have the same exact issue in the previous ROM?

Apparently 1.29.709.4 has been officially released in Taiwan by HTC, so it shouldn't be long before the update arrives to the rest of us (hopefully).

got the same issue...some times I got no lags in audio streaming, but sometimes they are there...until it (maybe) will be fixed I'm using a widget, my cousin has coded for me yesterday . Quite simple solution. If I press the button, wifi turns off and bt turns on...works fine for me, so far

BT disconnecting while hotspot on

Hello,
from MIUI 11 i am experiencing issue with BT devices disconnecting while using wifi hotspot. Once hotspot is active everything works for a while but then BT stops working and disconnects devices.
IT IS present Also in custom roms. Anyone Has this issue and know about some fix?
Many thanks.

Is your hotspot in the 2.4 GHz band ? If the answer is yes, try 5 GHz.

i will try, but unfortunately the client devices does not support 5ghz
i think it's a hardware issue as it does it with every, also custom roms...

It's mostly unrelated (at least with phone) but I recently started using a new small PC. The bluetooth disconnected too easily, even at less than 2 meters, a slight move of my head(phone) was enough to cut the music. Then I disabled the Wi-Fi interface and Bluetooth connection became robust even in the next room several meters away. That's probably because Wi-Fi and BT uses the same 2.4 GHz band.
Concerning Xiaomi smartphones, I use them everyday to listen to music while Wi-Fi is on (either in the 2.4 or 5 GHz band) and never observed a disconnection (xiaomi.eu or other custom ROMs). But I haven't tried in hotspot mode.

yes it's work as it should until i enable the hotspot, even then, it works sometimes for like an hour and then it starts... solution is airplane mode on/off and it works for a few again.
i use this a lot, as i do hotspot for kids and wife in the car, and i also work a lot remotely and this disconnects everything from BT audio to watch and it's really annoying. :/

I just made the test, phone connected to LTE and my home routeur in the 5 GHz band. Then connected in aptX HD to "PLT Focus" headphone. After that I turned on hotspot in the 2.4 GHz and I havent observed a disconnection yet (after 15 minutes). But I live in the countryside where the whole Wi-Fi spectrum appears almost unused. I usually can detect only one other access point with a very weak signal. So, even if I was able to test for several hours, it wouldn't prove anything as your use case is very different. It may come from interferences on the same channels used by others while your vehicle moves. I don't know if we can control what channel is allocated by the hotspot but it's probably dynamic. I guess that when you switch off then on, it just select another less used channel then it works again for a while.
