bluetooth headset and battery life - Touch Pro2, Tilt 2 Windows Mobile General

has somebody made any experiences with bluetooth headsets, especially stereo ones for music listening, and the battery life of the TP2?
how many hours could i be listening until the phone battery is empty?
cause i'm thinking of buying one(e.g. http://www.consumer.philips.com/c/zubehör-für-mobiltelefone/shb6110_10/prd/at/).
thx for the answers

I've been using my bt headphones just about everyday at work since i got my tilt2 about a week ago, battery life is comparable to my first tilt, a good half days listening if you aren't doing much else. Since i can't have my phone out b/c i work at a bank, it stays put away and just the music playing. I did use advanced config tool 3.3 to turn on all battery save options when i first got it, so i cant compare how it may have been right out the box, but i would reccomend to anyone to turn those setting on as i noticed a big difference with my first tilt. also im using the stock att rom with 6.5 and manila 2.1 and playing it with htc music player or whatever that default htc player is called. the sound quality is not good at all, but ive seen a reg fix here, and will comment back on the difference.

i tried the the 320 Line speed reg trick , it sounded horribe on both my jawbone II and sony HPs , I'm gonna delete the dword reg and try it stock.

By default the quality of the audio is terrible via A2DP. At first I thought I got a bad pair of headphones or that was just the way it sounded over bluetooth. However the linespeed registry entry made all the difference in the world. So make sure you set it and then reboot your device. It should be at:
HKLM\Software\WIDCOMM\Plugin\AV
then set/create DWORD entry: LineSpeed = 320 (Decimal)
That made all the difference in the world as far as the quality of the audio through A2DP.

How to use a BT Stereo Headset with GSPlayer or any player

I tried to set up a set of BT Stereo Headphones in a shop the other day to test them. We couldn't get them to go so we could listen to mp3s. I use GSPlayer.
Has anybody done this successfully? How do you tell the Magician (WM5) to output the sounds to the bluetooth headset and not to the normal headphones audio output socket?
many thanks,
Zaine.
Cant remeber where i got and who to give props too. but here it is
just run the output all audio to bluetooth and the run the other to turn off
and the auto mode which i havent tested out yet
Bewdiful.
Bewdy mate.
Thanks very much, that seems to do the trick. It works with my normal headset now. I'll go back to the shop now and test those other headphones.
The auto toggle seems to work OK as well, btw.
Once again, thanks a million.
Good deal. I gotta try this out. Will this work w/ the Wizard?
It doesn't work with my Magician + BHCS BT Patch...
I've read plenty of threads about this. For Magician, A2DP is WMP only. Doesn't work with anything else.
Mind you, this is what everyone else has said. I have not tested this myself.
I can confirm that, in my experience.
Also: WMP is pretty rubbish about its A2DP support. For some reason it'll only stream mp3s within a certain bitrate, too low and it uses the device's speaker.
It won't do non-stnadard sample-rates either, and on most setups it seems to "burp" every few seconds.
Ik am succesfull with the standard WMP though. It plays all bitrates, and only rarely stutters... So when I use WMP, I am satisfied!
Works fine, just bad quality sound with Bluetooth.
Well, I tried again in the shop and everything worked fine on my Magician (a T Mobile MDA compact with WM5). However, the sound quality was pretty rubbish. The sales guy reckoned that was a function of Bluetooth.
So, not a winner there. But, I can now listen to my voice recordings and podcasts via my normal BT Headset, which is really handy.
Thanks again to the Frioman - a really useful couple of apps. The toggle is on my Today page now!

Yeah, I got this all the time, espically if I fast forwarded and rewound. And I was re-encoding mp3s to different bitrates, constant and variable without much success.
"Damn WMP and it's lack of features! The stupid thing can only play MP3s... and... WMA..."
I did a few test re-encodes to WMA 9 (not 9.1) @ 192 and now I get those burps and crackles every ... ten minutes? Half an hour? Definitly not every... what, twenty seconds to a minute.
If this is a problem for you, try re-encoding to WMA 9 @ 192. I use dbPowerAmp http://www.dbpoweramp.com/
ooff! took me about 2 and 1/2 days to re-find this thread again!! can we get a sticky on this????
used this on my Wizard (aka mda) and my Moto H3 and now can listen to my tv shows on the train w/my bt headset!
thanks!!!
I got a Unable to Open bluetooth audio gateway or something, though my headset is connected...strange.

BT Audio User Problem
I downloaded BT Audio and installed the three .exe files on my 8525. Soft reset the device and then toggled the audio on.exe. Sound still coming out of the speaker and not the BT headset.
I do have the BT-620's and they work fine (even before the BT Audio install). I am trying to accomplish being able to listen to WM without having to lug the BT-620's around all the time.
I am wondering if having the 620's software is conflicting with BT Audio?
Also, I think to get the audio stream to play to the headset, one has to activate the voice dialing feature from the headset? I can get the sound to play only for a few seconds when I do this. Do I need to de-activate voice dialing? If so, how?
Thanks and Happy Holidays

Nosie With A2DP!!!

Hi I'm new to the site, i had read a lot post about upgrading roms from different companys, i read people describe how good the a2dp quilty is, but the problems comes, i first upgraded the rom to T-Mobile , then i found there are a high pitch nosie, at first, i though it was just my earphone, after i changed it, it still the same, then i upgrade to the QTEK rom, the nosie still comes, the nosie comes as the singer start to sing!!! it makes my so dizzy, i had try to link my BT to my PC, but they sound much different! no nosie plus clearer sound!
the second problem is that when a phone call-in, the ringtone goes via BT rather than built-in speaker???
the third problem is if you set ur BT as both hands free/set and wireless stero, during a connected phone call, if you press any button on the dial pad, all the sound will gone, but the phone is still connected, i found this problem when i using my voice mail?!
also after i update to the non-O2 rom, my phone is no longer accept any MMS, i already config all the setting from O2, is just that i don't have my MMS acount appear on my mail box. i also try the .cab setting file too!
My A2DP BT is i-Tech S35
ROM Version: 1.30.77WWE (QTEK)
Radio Version: 1.09.00 (QTEK)
ExtROM Version: 1.13.188 WWE (O2)
Many Thanks!!!
Was it just me than having this problem???
- I've not the first problem.
- I've the second problem
- I never experienced third problem
:wink:

Click on the above link , download the file and run it on your phone, do not alter any of the options, just click next on everything it will fix your MMS problem
thx a ur advice coff... but it still doesn't work, plus i starting to think that the nosie might cause by my s35, due to the campasility.. (sorry can't spell)
Hi MicmiC901,
Yes, it probably is something "locally" with your phone/headset/area/etc, since I also have same experience as asci, meaning;
1. NO, don't have that problem
2. YES, I have same issue (to me this is actually OK, since when headset is connected, I WANT it to only ring in the headset)
3. NO, never experienced this problem
I use the latest Qtek ROM with AKU2 and A2DP, but have never experienced that high-frequent-noise-issue you mention with any other of the A2DP ROMs on my JasJar (TMobile Germany ROM, a custom-ROM from the forums).
so RonnyGydar, which bt headset u using @ the moment? i just try with my friends logitech bt headphone, it get worse than my i.tech, sound get Stuttering , so i think i better change a new bt, would u recommand moto ht-820?
Hi MicmiC901,
Sorry the veeery slow response...but now I have even one more BT Stereo headset...so then you get the "bonus" of even more info in my reply!
I have 3 BT Stereo Headsets, and here is a short summary of experience of them all.
HP BT Stereo Headphones (same HW as the Logitech ones as I understand).
Sound is good, clear, OK bass. Nothing exceptional, but I was very pleased with them. Sound could be a bit higher at the highest volume...if you plan to use then in noisy environments...but not really an issue...since they are quite loud.
Motorola HS820
Soundwise (clarity and bass) very simmilar to the HP ones...can't point my finger on any differences. But they seem actually a little less loud than the HP ones...so with these I struggeled to hear Podcasts when I sat on a bus going through tunnels. The HP headphones are slightly louder, I think.
Bonus of these are the excellent batterylife and miniUSB plug...plus the HP ones do not have a microphone, so the HP ones are only for music. So I would easily chose the Motorola's before the HP headphones.
One minus for me with the Motorola's are that they hurt my ears after a couple of hours of use. ...that at lack of "powerfull" bass, got me to look at the i-Tech BluePRO's...
i-Tech BluePRO
These have very good bass (and they sure look like they should have it too...pretty big earmufflers...with these, you look like you are working at a construction site or something, but the clarity of the sound is actually worse than HP and Motorola...they sound a bit fuzzy.
...but I still use these all the time...mainly for two reasons. One is the excellent bass (I like to listen to techno and trance...and then bass is important, the other is that they isolate outside sounds (due to the enormous padding), so I can have the sound as low as I prefer...and STILL hear all my music without disturbance from other sounds in the environment (like sitting on the bus in a tunnel, or at a noise Gym).
It also seems that there is quite a bit difference in how the different manufacturers implement BT profiles.
My Motorola and i-Tech BluePRO have problems with "Pause/Resume"-button on headset when used with my JasJar (Pause works, but not resume...or opposite...not sure which it was, dont have the headsets with me today)...but the HP ones does not (I tested them a couple of times, and the HP headphones worked all the time)!?
Re-connection after a time without use seems also to vary a bit. The Motorola I can turn off/on the headset, and they reconnect automatically to my JasJar. The i-Tech BluePRO's I must choose re-connect in "Bluetooth settings" on my JasJar every time I want to use them.
The "famous" "lag-issue" everybody experiences I experience with all my headphones in some situations...and it does not seem any better or worse among the headsets. It seems to also be affected by general radio disturbance, since I have a lot of problems with lag at work, but no problems at all at the Gym (which is good for me...since that is the place I am most happy with having my wireless headphones), and some issues at home.
Hope this was of any help!
actually i have the problem micmic is talking about.. it happened when i upgraded my wiz to a newer rom to get the a2dp function. eventually i do not have a bt.stereo -headset yet.. (coming in about 2 weeks) but i have the issues with the sound. it's almost like a bad bitrate or something? ..wierd it is since i remains even if i downgrade my rom. =/
Hi epluribus and MicmiC901,
Is the "stuttering" you both mentioning the same as I call "occational lag"?
IF it is...it you should certainly not have it when you do the following test;
1. Reset your JasJar/Universal (to clean memmory completely)
2. Started listening to music over headset with...
3. The Universal lying on the desk in front of you completely still 50cm from your face
4. You sitting completely still
5. No WiFi on close to you.
...this test is completely overkill...but if it STILL stutters in that "controlled scenario"...well then it must be something different with your Universal or headset HW. Cause I can walk around with my JasJar (also in areas I know there are 5-6 WiFi connections active...like my appartment), and even put the JasJar on the table and walk 5-10 meters away from it...and have no or at least nothing more than an "occational stutter"/"lag".
It seems to be two major factors affecting this "stuttering"/"lag" (from my experiences at least...I have used A2DP a lot with my Universal...couple of hours every day);
1. Universal struggling outputting(RAM/CPU...or both!?)
One help here is to apply the registry "A2DP priority" fix (found it in the forums here).
Another is to close all programs before using it (I usually do not do this...I usually only do it in hindsight when I get the problem).
2. Signal between Universal and headset struggling (obstructions between Universal and headset, WiFi nearby, so forth)
I for example get this problem if I put my Universal in my trouser pocket (I know, I must have big pockets, and walk around, I get stuttering/lag occationally. If I then take it out, and hold it in my hand farily still when I walk...no stuttering. I have found, that when I walk, it is OK to have it in my backpack/rugsack...then for some reason it very rearly stutters...so I usually do that.
But when I walk of the bus at work, and walk into the "campus" of my workplace, which is cramped with radiotransmitters (is norways largest Telecom company)...I get a lot of stuttering, and need to take it out of backpack, and hold it in my hand, at it gets a lot better.
In short: A2DP with the Universal works, but is sensitive to disturbance/obstructions/moving around...and to make it worse, it is also sometimes dependant of the Universal itself struggling with CPU/RAM.
I have BTW had the exact same problems before with Qtek2020 and Qtek9090 (which I got hold of some "A2DP patches", when I had those devices). ...but I really had a LOT more stuttering with those two...so much so, that I never used A2DP with them on a daily basis.
...so it can seem that HTC is getting slightly better on each new device...?
Hope this info can be of some use!
...but it might not...if my assumption at the beginning here is wrong, and your "stuttering"-issue is something completely different than the "lag"-issue I talk about!?

Bluetooth stereo headphones advice

Hi everybody,
I´m planning to buy a bluetooh stereo headphones for listening music and hands free calling.
I´d like to have:
- Controls for controlling mp3 playing, volume and phone functions (hang,interchange calls....).
- Screen for seeing mp3 tags and caller id.
- High battery life.
- Voice calling.
Any idea on what to get.
I have a qtek s200 (g4 prophet) rom: 2.20 spanish.
Thanks in advance.
I have been usin` Plantronics Pulsar P590. No problems so far. Qulity is very good, all necessary controls for controlling mp3 playing.
Thanks very much for the advice, but it doesn´t have screen.
Best.
Read http://forum.xda-developers.com/showthread.php?t=296770
After reading your great post and some links you have on it, i realized that it seems that i´m looking for something that doesn´t exist.
The only options i have considered after reading, are sony HBH-DS970 and nokia HS-12W and no one can manage mp3 tags on screen and the battery life is not so good.
Maybe is time to wait to someone comes whith what i want.
Thanks a lot.
I'm intrested in where you think the screen should be on "headphones" in order for you to see them? I think a far better idea would be to have an extra button to press that gives you a voice prompt/annoucement that reads the track title to you. I've seen some half-baked attemps of this on the PC.
Thinking about it, can't MS Voice Commander do this if you speak to it?
Like this will be ok for you to see it when you want without taking out your phone.
http://i.expansys.com/i/b/b131639.jpg
I prefer this than the phone telling you each song title.
I like this headphones. The problem is that it doesn´t show, i don´t know why mp3 tags and the battery life is not so long.
Will see if someone come with something good enought.
Best.

Universal and Jabra BT620s problem

Hi everyone. Not long time ago I bought T-mobile MDA Pro. I guess it's German version since it have QWERTZ keyboard layout.
It has some issues, but it was all software and I fixed it. But I have one problem that I couldn't solve my myself.
I have bluetooth headset Jabra BT620s. Bought it specially for using with my Universal (it's not handy to talk by phone with it in hands). Connected, added as Headset. Everything cool... have to be. But! It plays sound (as headset) this way: 1-2sec playing 30-40 sec silent. I didn't try hands-free because it have no use without listening to music. What had I try:
1. Different ROMS
- WM5 WWE 1.30.77 (if remember number right)
- WM6 J's WWE 2.02.02
- WM6 WWE 2.10.02
ALL ROMs had this issue
2. On every ROM I tried to change "priority" for A2DP (via RegEditor)
One thing helped me. Got broadcomm BT stack application (same was with WM5 ROM, but it seems different version). A2DP worked fine, hands-free too (as you remember I didn't try it without A2DP), BUT(!) all sounds via speakers and headphones (of course, when Jabra was offline) disappeared and my universal becon unresponsive and hanging up often. So I couldn't use it.
Maybe you can help me to solve the problem? Maybe I have to use different BT stack? Or try something with registry? Or... I have no idea.
And, by the way, does anyone knows which broadcom chip is used in Universal? Where can I get all specs (chipset e.t.c.)?
Thanks
Hi,
I had the same problem with my Universal and my Laptop too.
I thought it was a lack of memory problem but trying "light" player nothing changed...
I think that it could be related to pairing problems and the way Jabra BT620s activate BT profiles, because everything got solved restarting Jabra and activating Headset profile before the A2DP.
I solved definitely all the issues with Jabra BT620s using the new firmware with WM6 5.2.1413 and Microsoft Stack (with bitpool set between 30 and 36).
I hope being helpful.
Let me know if you have any interesting tricks...
Hi! Thanks for posting!
I forgot to write that I always trying to activate hands-free firs then headset. And all after powering on Jabra.
Ok. I tried to update firmware of jabra (as topic somwere nearby tells) and connect. Problem persists.
I'm not kinda pro in BT, so tell me what is _bitpool_? And how to set it?
I will google for sometime, of course, but if I won't find that, please, write. Does this mean to mess with registry?

That is in the Registry. I got the info from somewhere (Sorry cannot remember?) But I copied it to a text file, here it is: [HKLM/Software/Microsoft/Bluetooth/A2DP/Settings]
Add new dword, Value name=BitPool; Value data=48 (Decimal)
Modify, Value name=UseJointStereo; Value data=0 (Decimal, Originally 1)
For BitPool:
Microsoft suggests the following bitpool values for optimal buffer sizes.
30 - Low audio quality
40 - Medium audio quality
48 - High audio quality
58 - Excellent audio quality
Choosing 48 is adviced.
For UseJointStereo: use 0 instead of 1 else the streaming is done only in mono mode!
(I have a 8525 so AD2P came with it. I never added any entries I just changed the #'s. )
Gonna try it today, when back from work.
I understand that reducing quality gives better stability and performance. But I want true stereo, not joint.
Ideally I want get same sound as I'd have in wired headphones.
I have the same problem with this headset, after 6 hours testing, severals flashings with the best wm5&wm6 roms, i cant make it work!
Please help, i had changed the bitpool from 30 to 60, one up at a time (30,31,32...60) nothing happens.
I heard half sec music and then silence. WTF???
try to use widcomm stack. but the quality of music in mine headset using this stack is not very good. and there are some bugs such as no sound after disconnecting the jabra. if you find some solution, please post it here!
widcomm stack works great, finally after 6+ hours i heard sound from my headset! The sound is pretty good, also when i turn off the headset, the sound playback from the device.
f#ck you M$ with the crapy bt stack, i have lost half day.
Thank you l2tp.
Solved!
It was a bitpool. Little gude:
It was my WM6, so no keys were added.
Use registry editor
[HKLM/Software/Microsoft/Bluetooth/A2DP/Settings]
Value name=BitPool; Value data=48 (Decimal, Originally 30)
Value name=UseJointStereo; Value data=0 (Decimal, Originally 1)
Value name=MaxSupportedBitPool; Value data=500 (Decimail, Originally 30)
As I figured out, MaxSupp is some kind of "cache". When I tried 100, it became laggy after 30-40 minutes. But with 500 2hours played perfectly.
But! Have to solve 2 more problems:
1. Bad connection.
I'm carrying my Uni in bag and when comething getting in the way between bag and my head (i.e. my hand when I taking something form the bag) sound dissapears for 1-2-3 sec. It's not nice.
Maybe I should try widcomm stack? The question is where I can get it and what the type it should be? (don't post please "on widcomm site", give me as widcomm.com, I just can't search for now)
2. It's too quiet.
Wired headphones were pretty louder. Since I using subway 1.5 hours per day you can imagine that without 100% volume I can't hear the music normally.
I put Jabra on 100% and Uni 100% volume. But it like 50% of wired headphones' volume.
Should this be normal (Jabra less quiet), or can I do something?
YES! I know how it works, that Jabra have internal amplifier and BT signal decoder, but...
Of course, I don't wans to dissassemble Jabra and making hard additions to it (unless it will be a kind of volume regulator).
I need that Jabra played for nearly 5 hours. So I can spend attioional power of Jabra (in manual said that It can play for 14 hours, so I can get 195% boost in power).
Thanks everyone participated in this tread.
Argh! The M$ stack gives me creeps. Very unstable. It seems, that my Uni have not BT but some kinda radio transmitter back from WWII! Loosing signal in distance less than meter! I alwayes hated, will hate always M$ corp. OpenSource rules the world!

Suddly or not, MS rules the computers world.
I cant understand why the p3300 works fine with jabra bt620s, and it has wm5.
I am still use broadcomm stack, not only works fine with bt620s, but also better with my gps receiver.

Tweaking Bluetooth Stereo settings?

Wololo,
I tried pairing up my Sony DS-980 stereo bluetooth headset with my Touch Pro 2. That worked flawlessly. I find the new bluetooth interface to be quite good. It has lots of fancy settings in a nice GUI.
BUT
When listening to music, the sound through my headset isn't very good. It sounds compressed and.. mediocre. I know it's not the headset, as it worked fine on my HTC P4350 (after some tweaking in the bitpool, that is).
I used to use Advanced Config for tweaking the bluetooth stereo settings. Apparently our Pro2 uses a new bluetooth stack which is not (yet) configurable through that program. I then tried searching for ways to edit the equivalent of the bitpool for our tp2's widcomm bluetooth stack. An old thread on xda stated 'Line Speed' to be the new 'bitpool' name. But that string is not in my registry. I might try adding it, but I doubt if that will work.
I also found 'Baudrate' as a candidate. but it's set to 4.000.000. That's quite high, in my idea.
Before I mess up my registry with 'playing around', does anyone know what else I can try? And am I the only one experiencing poor sound quality through stereo bluetooth?
Thanks!
Hi,
BT Stack on Rhodium is from Widcomm.
You can find the config in
HKLM\Software\Widcomm
I have not dug through to find ASDP settings, no time at the moment.
Please post back if you find it or not so that I can add them to the tweaks sticky.
Not sure if you have tried this or not, but with my car kit (which support HFP, A2DP and AVRCP I have to activate Stereo Audio on the Rhodium in BT Config, perhaps your headset behaves the same. If I do not audio is ****.

OK, I think I got it. The Linespeed value does indeed seem to have an effect. I used this wiki as a guide:
http://wiki.xda-developers.com/inde...h your stereo Bluetooth headphones? Read this!
I used Resco Explorer Registry add-in to add the following DWORD value:
HKLM\Software\WIDCOMM\Plugin\AV\LineSpeed with a value of 320
That seems to do the trick. I'll test it for a bit, but I'm not experiencing drop-outs as of yet and my music sounds much better.
PS I first tried hacking around in the HKLM\Software\WIDCOMM\BTConfig\SerialTransport; increasing baudrate/bytesize values. Don't. Changing stuff breaks the bluetooth
yesterday i tested the a2dp range and it auto reduced quality the further i went. Unfortunately it did not vice-versa.
I'm going to test that reg.
EDIT: Definitely that reg works but it also makes the cpu use heavier and you notice that while using gps software on the car and streaming music. The 528mhz cpu is not powerful enough for this task. After some testing the value is like kb/s, so 272 is the usual for good quality, above that it takes allot of cpu. At the end i removed the reg because the device does the auto quality/cpu usage quite well. The quality is not quite the same has with a fixed value of 272 but barely worst.
Yeah, I noticed the same thing with the distance and quality, which kind of sucks as over time if the signal weakens for what ever reason (which will likely happen over an extended period of time) the audio quality gets worse and worse over time.
Also I have noticed that Audio controls don't seem to work on the TP2 with my BT stereo headphones (Sony DR-BT21G) and seem to play at max volume all the time. Not sure if this is something you guys have noticed as well or if it is specific to my head phones, though they have worked fine with other devices.
if you google it you will find ppl with dell and hp pda that uses/installed widcomm/broadcom stack and "unfortunately" it's a feature. The volume is controlled only by the a2dp receiver.
The linespeed does work but try and use wifi and a2dp at the same time You will get so much skipping :S My best experience is without that reg. Not the best quality but.. You will live with it.
Also it does adjust the "quality" itself. Lowers and uppers. It's just not instant.
anyone figure out the reg settings so it will force the call to use ringtone?
