Hi,
I was wondering if you have any info about the BT 3.0 not working properly. When i bought the phone (stock JF5), i tested the bt transfer with a s8500 wave and it was transmitting at bt 2.0 levels. i have jpc now and tested the bt transfer with a friend that has sgs/jm1 and again the bt transfer speeds were very low, no way near the bt3.0 advertised transfer speed.
Do you know if this is a common sw/hw issue or is it happening only to my unit?
Thanks in advance,
Adrian.
BT 3.0 doesn't automatically means you get faster transfer rate
BT 2.0 protocol specs for data transfer is about 2Mbit, meanwhile the 3.0 protocol is not finalized yet
http://en.wikipedia.org/wiki/Bluetooth
if you see anything faster than 3Mbit, then it's already using the BT3.0 protocols

Is Kaiser BT using EDR? With 8525, my BT Internet sharing speed would max out at about 280Kbps due to the limitation of the BT stack [non-edr].
If Kaiser uses BT2.0 with EDR, in theory, one should be able to get data speed twice faster on HSDPA network.
Let me know if anyone has tested before. Speed test on a tethered laptop via BT should give us a good idea.
No one has tried BT tethering?
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.
akey
HTC TyTN II (Kaiser/P4550)
Rom ver: 1.82.707.0 WWE
Rom date: 11/03/07
Radio ver: 1.27.15.32

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.
Hi there, my fellowmates.
An HTC Touch was given me by my employee so I bought a multipoint BT headset - Plantronics Voyager 835 - hoping to use both the Touch and my old - and stil 100% - Alpine/QTek 2020i.
Everything works fine between the pda's phone calls when the Alpine's battery is full; but when the battery drops two thirds of its capacity and I receive a call from Touch I loose the Alpine connection, so I have to 'unpair' the headset and add it again as a 'paired device' ... until the next time I have to pick up from Touch, and so on and so on...
Then I charge my Alpine and everything works fine, until the cycle begins...
My question is: Since the Alpine's BT version is 1.0 and the Touch is 2.0 could this create somehow an incompatibility and be the problem?
If so, is there any chance I could upgrade the Alpine BT version to v. 1.1 (at least) or v. 1.2 from a newer ROM and in a simple way, say, by coping some .exe/.cab files or only upgrading the BT files)? I mean, only BT, 'cause everything else works smooth.
Appreciating in advance your coments and help, I send to you all my BRegards.
So, guys, not even an idea? Out there are so many experts on many things and here nobody risks a suggestion at least? In Portugal we have one dictated: "while wait, seat you, for not getting too tired" - therefore I am "seated" waiting...
I have both a ME57C and ME572CL, running 5.0.1 WW, and they exhibit the same problems with bluetooth, which seems to rule out a unit-specific problem.
1/ BT audio works fine in headphones mode (ie stereo listening only), quality wise, but fails as a headset on the audio-in front (tested with two different BT headsets, including a JABRA BT3030) : audio in comes garbled and clipping to the point of uselessness.
2/ Whenever BT is active, it seems to interfere with WiFi networking, leading to frequent drops and reduced throughput on WiFi connections (both TCP and UDP).
Other features of BT seem to work OK (file transfer, keyboard/mouse connectivity, etc) although I haven't tested those extensively.
Anyone with similar issues or clues as to fixing the problem(s) ?
Have you contacted ASUS to ask for support or at least to make a bug report?

Not yet : I'm asking here first to see if it's a non-official-yet-known issue (I couldn't find anything on the ASUS support resources), my experience being helpdesks work best when the users do their homework.
