BT audio Skipping... any workaround? - 8125, K-JAM, P4300, MDA Vario ROM Development

HI,
i still dont know if the audio skipping with AD2P headsets is a hardware issue or an OS issue.
The problem is that i can not use AD2P and SPP (Serial Port Profile) at the same time. The SPP works fine but it starts skipping the audio.
I get this when i try to use my headsets and the GPS at the same time.
I wonder if this happend because the Wizard has a 1.2 BT stack and not a 2.0.
Anyone using hermes has this problem?
Did someone try using other BT stack?

i think it has more to do with the radio..
i noticed some AD2P headsets do not conform to the rulez set to it.
as wizard has 1.1 bt stack it probably wont work well with 2.0 devices allthough it should.. this u'll see most in the bandwith usage.. device made
for usb2.0 use more and wont do well if this bandwith exceeds that of an 1.1 or 1.2 BT stack
might try this ext gps router in wm6 .. its in settings>connections>ext gps
and route it to a com port not used

Bluetooth Headset

I was reading around about issue using BT headset with the Himalaya (W2003 not second edition!)
I read several people who installed the WidComm stack, but as far as I have understood, with this hack there are still problems with the headset profile (still I don't now which!).
Talking about the standard MS stack, I read people using Nokia BT headset complaining about it loosing connection and turning off after 10 min. Is this a nokia only issue?
It seems that Jabra hs are working well. Is there any known problem with the standard MS bt stack?
Thanx to anyone who will/could help me reorganize my mind...
Regards,
Francesco
I have a bluetake G2 headset. When I had 1.72 ROM and installed Pocket Bluetooth Tools it worked perfectly. Currently I'm playing with SE ROMs and have not yet used this headset with it.
Widcomm stack does not support headset/handsfree profile on our device. It can bond with headset, but you would not hear any sound.
I am still using the MS BT stack with rom 1.72.00.
NO Pocket Bluetooth Tools (I would like to know why mamaich uses these with a 1.72 rom . . .)
NO issues whatoever with both Headset (Headset Protocol) or GPS (Serial Port Protocol).
Just rocksteady . . .
Bluetooth Activesync not working after PBT
Activesync over bluetooth doesnt work anymore after loading Pocket blue tooth tools,( it was working perfectly well till loaded PBT) It doesnt even give me the option of syncing via BT ( the option one normally gets when one opens activesync on the device ( tools menu 1) Options 2) via IR 3 ) Via BT ) now all I find is options and activesync via IR.
Bluetooth HS810 Microphone not working
I am using a Motorola HS810 bluetooth headset with WM2000SE-Sin-Merged-v2.0 on an XDA II. When I complete pairing, 3 pop-ups all happen at once asking various profiles supported by the Headset - Serial, Headset & Handsfree. I answer yes to the hands-free. (It's only possible to see the other pop-ups due to the handy alt-tab applcation supplied with this ROM version!)
The earpiece works just fine, but the microphone does not. I need to speak into the mic on the XDA II to be heard.
...I have now reverted to 1.72.00WWE & all is fine. It seems to be a problem with WM2000SE....
Any ideas?

BT stack problems - need working A2DP for PDA2

Hi, I have read a lot about updating the BT stack to allow for A2DP on my PDA2, and especially a previous post (XDA2i - bluetooth stuff - newbie question) where the solution was to install the BroadcomCorporation BT-PPC AV.cab file. I did this and it does give me the High Quality Audio profile when bonding and the bonding process seems to work fine. However this results in no sound from my PDA, nor any from the headphones when playing audio! (which by the way are the Blueant BT headphones). Headset mode works fine still. I have tried all the different versions of the BT stack on the ftp site but no joy. Is there something else I need to do to get this working, and is this, maybe, a problem with the PH10D, but not PH10C ??
I am really stumped so any help, suggsetions or pointers greatly appreciated! Thanks.

MS BT stack + pairring problem with carkit

Hello,
Bt MS stack is apparently not compatible with all BT headset, hands free en car kit devices. I have been trying to pair my pocketphone pda with a pioneer car kit without a successful result, the image of the hands free appears on the BT manager ‘as pioneer BT unit’, but the standard pin code 0000 or 1111 is always rejected.
Pioneer technical service couldn’t help, they say normally it should work with almost all BT headset devices and a compatibility list of the product is not available.
I guess the problem lays on the BT package. Is there a way to solve this issue by creating for example a BT compatibility patch, or changing something in the registry to make it compatible. Widcomm stack is better en compatible than the MS stack according to many users. Does anybody have any clue?
My device is upgraded to WM6 with always the same sad result.
Thanks
Hi, I have a pioneer bluetooth stereo in my car too, Found it a bit difficult to get paired at first, but it eventually worked. Although it would not give me the hands free profile, only the headset profile, which means I have to initiate and anwer the calls from the phone :-(
thinking about looking at the widcomm stack if I can get it running on WM6
For your information, I have tried the widcomm om my device ‘the last version’, but when I click on the bt icon in today screen, the blue led start flashing for a while but stops with “ memory storage error” . There are some bugs which should be corrected or some registry hack to get it work. However, the widcomm is far much better and stable than the MS BT stack ‘this later sucks’.
Apparently, you have a built-in bt unit, I have a pioneer 6800 + BT unit device optional, it worked perfectly with my old qtek 9090 as a hands-free and an BT audio device without any problem.

A2DP Issues

Hi all,
Laurentius and I are looking at resolving the current issues with A2DP (Many fixes will be in our latest rom, however issues vary from headset to headset.
Some work fine, others are poor quality and some receive PDA lockups or long pauses between streams.
Please could those with A2DP issues, and the need for this protocol to work properly, post the following information.
The current Rom you are you using
The make and Model of your headset
A list of issues you are currently having with A2DP.
Please also try the following to resolve the issue.......
HKLM\Software\Microsoft\Bluetooth\A2DP\Settings\
Remove (Delete the following entries)
BitPool
MaxBitpool
and add the following
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\AudioGateway]
"Capability"=dword:0000003C
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\A2DP\Settings]
"SampleRate"=dword:0000BB80
"UseJointStereo"=dword:00000001
Please then remove (un-pair) your headset and Soft Reset
After SR please re-pair Headset and test A2DP again.
Please keep this thread clean and only post A2DP issues with the required information listed above.
Thanks,
Cheers,
Beast
Hi Beast,
Isn't:
"UseJointStereo"=dword:00000000
to get proper stereo sounnd?
Regards,
KOR!
I have latest V1 rom from Lt.Cmdr.Ivan - BT headset is Philips SHB7102 (works great with my Wizard and SEk800i). I did exacetely what U have asked for (but i have left jointstereo=0) and nothing happend. It sounds like 2s of music folowed by 15s of silence, then again 2s of music and 15s of silence. I messed with bitpool walues and couldn't find any working set. I'm afraid that's something wrong with max BT speed and not with A2DP implementation. I had BT speed switch app when I used broadcom BT stack and A2DP works great. Unfotunatelly normal mono BT headset doesnt work at all with this BT stack so I'm back to original stack

I've found that with MS stack and my Jabra BT620s the best bitpool is 33... good quality and good range (no interruptions)... jointstereo must be 1 otherwise the sound uses too bandwidth...

I also have Ivan's V1 Rom and have an Itech Radio headset. I completed the changes that you suggested and found that A2DP works well it did before the changes too. I have noticed that the sound quality may be a little better and the pauses are slightly reduced.
The main problem I have found with A2DP with all AKU0.5 ROMS is the pairing of the headset. If you soft reset you phone while the headset is on, A2DP will be auto detected when the phone comes up. If you play music then the music starts and stops and the phone becomes unstable. The work around is to turn your headset off, soft reset the phone. When the phone comes up turn the headset on and activate A2dp by pressing the button on the phone. Music then plays fine.
The registry changes you suggested did not help the above problem. AKU0.5 ROMS all seem to have this A2DP autodetect error on reset at least with my headset. Very frustrating.

Hi Maniware,
Can you please further shed light in detail on the jointstereo?
Why jointstereo to be 1 or 0?
Thanks in advance!
KOR!
It goes well with joint stereo. Seems that it needs much less bandwidth. I've heard that jointstero=1 means that there is mono sound in effect.
"UseJointStereo"=dword:00000001 << mono
"UseJointStereo"=dword:00000002 << joint stereo
"UseJointStereo"=dword:00000000 << stereo

qtek 9000 - Logitech Mobile Bluetooth Headset
I'm not quite sure if my problem is right here - because i still have the original (last build) WM5 ROM (130.96 GER, Radio 1.09.00, ExtROM 1.30.185 GER).
I encounter statics while using the Logitech bluetooth headset, which is a mono one, making phone calls impossible due to stressed phone partners ... Only the person on the other end of the line encounters interruptions, me, as calling, not.
This is the main issue for me to update the ROM, and I'm trying to find out if any of your nice new ROMs will be of help.
Anyway, I haven't tried yet I'm afraid to destroy my device ...
thanx
Anna
my feedback:
device:
itech r35
Problems:
sound muted after 2 seconds of music.
audio players used:
audio manager
windows media player
i tried your advices, but not worked for me....
Sometimes it works when i put 70 (binary) on both Maxbitpool and bitpool...but on next device activation or reboot it just stop working...
A2DP and wireless
Just to be clear, my results are when I do not have wlan activated.
I changed UseJointStereo=dword:00000000.
Quality is good and it is definitely stereo.
Still have the auto detect problem. Interesting though, if I walk out of range for a while with the headset on, when I come back into range the A2dp is autodetect and the music starts playing through the headset again, quality is good. If I soft reset with the headset on and A2DP is autodetected, the headset is unusable.
If you do any of this with wlan on the quality is very poor with starts and stops.
Also noticed that audio manager does a better job with bluetooth than gsplayer, I think audio manager may have better caching.
Freezing
I think there's a problem with the latest core os files (AKU 0.7.0)... i havent' tried the MS BT stack, but with the Widcomm, using the bluetooth for anything more than 1 min, completely freezes the phone.
It does when listening music, transferring files, etc... if BT is idle, nothing happens (except than freezing the device when the Comm Manager gets confused and enables BT instead of gsm radio).
So it seems related to the core files.
Switching on and off, transferring data thru BT is a critical task and subject to lockups.
For the record, i used to use the BT A2DP and file transfer without ANY problem whatsoever in my old and horribly-underpowered HTC Tornado (omap850 @195mhz) so IT MUST WORK!
im using your latest rom and Motorola HT820 does not have a problem with it... even in the earlier roms you cooked... even tried it in indra's xoj version and darkforce's rom..
just wanted to clear it out just so you can rule something out...

A2DP problems should go away, but then will come the freeze-after-1-min problems, like with my HP Stereo bluetooth headset
I've flash to your latest WM6 AKU 0.7 (WIFI Fix update 3) ROM just now. But sadly to say, the freezing thing still occurs after playing music with Audio Manager. It even freezes when watching videos using WMP. Usually around 1 minute it shall start freezing. FYI:

I had the Qtek 9000 with italian version WM5 and i flashed WM6 with no problems. if you dont wanna have any problems unzip the attached file and add in the folder the 3 files (ms_.nbf ; nk.nbf ; radio_.nbf) from your prefered WM6 ROM (I personally use the latest Laurentius & Beast ROM http://forum.xda-developers.com/showthread.php?t=325466) start into bootloader (Power+backlite+softreset) and ROMUpgradeUt.exe
VERY IMPORTANT: you have to charge your batery before any flashing

A2dp motorola S9+windows xp

first off, major props to the xda community, you guys are the best!
now for an interesting problem/project:
It's been a month since I've purchased my Motorola S9 bluetooth headphones http://www.motorola.com/motoinfo/product/details.jsp?globalObjectId=177 and have been amazed by what I can do when combine the S9 with my HTC touch and cyberon's voice dialer which is a voice activation program
I use it to:
listen to stereo music
launch programs
stereo music remote control
speed dial
raise and lower volume
teach iphone users the meaning of envy
just being able to do that with with the a2dp remote and microphone of the s9 makes it feel like it's 2030 where people are wired to computers and technology is transparent and everywhere. The s9 feels like sci fi technology... almost. the s9+htc touch is a great no hassle way of getting the information you want pumped into your ears
so as a tech enthusiast I've asked myself,
why the hell can't my computer do this?? i mean, it's 2008 and I'm still using a keyboard and mouse for everything?
I'm trying to make the S9's work on my mac book pro running windows xp+bootcamp drivers but windows doesn't even support a2dp much less handsfree wireless mic profile
i've an online tutorial by katy hxxp: www.djkaty.com/drupal/vista/bluetootha2dp but installing broadcomm's bluetooth stack gives me an error telling me that there is no bluetooth radio device detected which is total bull as i've been able to send files to my HTC touch via bluetooth. I've also tried installing another bluetooth replacement stack called bluesoleil; with no luck
I've also am about to start trying adding widcomm using this guide (http://www.dev-toast.com/2007/01/05/uncrippling-bluetooth-in-vista-rtm)
but in the guide said a2dp doesn't work with widcomm
anyways how do i make bluetooth a2dp work and my s9's mic to work via bluetooth on pc? is my ultimate question
also, if you could recomend a voice activation program that works as well as cyberon's voice dialer I'm looking for the type of functionality where I can press the voice button issue a command and then good stuff happens I bet lots of other people thought of doing the same thing like this
could you please help?
A step by step guide would be aprechiated
update: I've been able to install widcomm drivers version 5.1 and everything works... except the a2dp UGH!

BlueSoleil, with some external BT dongles, does support A2DP. It's just that the BT dongle itself must support it in hardware.
That is, shop for an external BT dongle if you do need A2DP.

thanx but i'm trying to get my internal laptop's bluetooth to use it I've heard good reports that i'm just using the wrong version of widcomm drivers.... time to reinstall everything...again
besides who wants to carry around a laptop with a dongle flopping around? i'll try to avoid the dongle solution if i can
A2DP and bluetooth stack
Having same issues here. My goal is using BOTH A2dp and Blackberry wireless sync via bluetooth (just a serial port).
I find it impossible as Blackberry will only work with native xp drivers and A2DP is not supported in xp.
Currently i gave up wireless sync and am using A2DP with Bluesoleil, which works fine for me.
Anyone ever tried using A2DP WITHOUT switching to a different bluetooth stack?
