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?

I have a need for a BT repeater, http://omni-wifi.com/mobile-spot.html , will repeat any frequency from 2.4GHz - 2.483.5GHz.. This is the same as BT. It does not latch on the the SSID of a WIFI router like the other WIFI repeaters, it "repeats" on the frequency level.... HOWEVER, it does not do well with frequency hopping like with BT 1.2.
So, is there some reg setting in my PDA2 that can switch it to 1.1?
Or is it something in the BT stack that is unchangeable?
I know the hardware is the same and the only difference between 1.1 and 1.2 is the frequency hopping.
Or, does any one know if the frequency stays the same during a connection.. For example, does BT1.2 hop around and search for the best channel during "standby" and then picks a channel and sticks to it during the active connection?
FYI, I need this so I can leave my phone in the work truck and only use my BT headset because I have a cell phone repeater in my work truck and I travel outside normal cell service all the time.
Thank you
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
Hello.
Does the bluetooth on your Kaiser or Tilt work through walls?
I have a mac pro which has a very good strong bluetooth signal and I can connect to it via nearly all of my other PDA's however my Tilt cannot see the mac pro through any walls.
I have tested the range of the bluetooth by placing the Tilt on a table and playing an mp3 to my Jabra BT620s's and in direct view of the phone I can get about 25 ft from it which I believe is quite acceptabe but the minute I try to connect or maintain a connection throught a sheetrock wall it cuts out.
Does anoyone elses unit do the same thing? Or do I still possibly have a defective unit?
Any ideas?
Tom
Am I the only one who notices this?
BT uses the same 2.4 GHz frequency range as 802.11b, so it should theoretically work. However, BT uses somewhat less power than WiFi, so you may not get the same range.
I have a Sony MEX-BT5000 radio in my car, which is paired with the phone. My garage is about 20 feet from my living room, with one wall between the two rooms. Sometimes, when I forgot to take my old Wizard with me, I would notice the Sony pairing with the phone, only to lose the pairing as soon as I back out of the garage. So it is possible for BT to connect through a wall. However, I haven't forgotten my Tytn II yet, so I haven't been able to test its BT performance.
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

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.
hey guys, I'm running the ultimate-X2 rom pack from here and I can't seem to get the configuration of my blue tooth working with my EEE. I've tried BT DUN and it keeps reporting back that the modem is out of order, any ideas?
Do you have active sync on the computer? I don't remember if it needs it or not for BT.
yea AS is on there and everything works as it shoudl through a usb cable, just can't get DUN to work or PAN
Are you using WM5 or WM6.1? I know that with 6.1 you need to use the Internet Sharing app.
Also, which Bluetooth stack are you using? I got it to work on a Toshiba BT stack, but once I figured out how to AS over BT, it stopped the net sharing from working. I think you can only have one pair at a time. I'm not sure though. I'd also like to know how to get both working without interfering with one another.
WM 6.5 and i'm using the built in bluetooth adapter on my EEE, no idea what stack its using
I got it, didn't have my pair set up right and PAN was the proper way to do it and use IS on WM. the modem trick was a no-go and worthless IMO
Good. Glad to hear you got it working. I got my internet sharing to work once, but once I set it up to ActiveSync over Bluetooth it stopped working. I guess when it's paired once it won't let it be paired again. Anyone have any support for this? I'm using a Toshiba Bluetooth stack (sadly... thinking of switching to MS stack) and a Tilt ROM.
