BT Stack newer than Widcomm 1.5.0 Build 801 available - Windows Mobile Development and Hacking General

These stacks I believe are newer than the Widcomm 1.5.0 series
I think Broadcom reset the version 1.0.0
These are Broadcom 1.0.0.3000 and Broadcom 1.0.0.3500
Build 3500 is slightly unstable but newer.
These came from an i-mate patch for a PDA2K.
DO NOT USE on an i-mate PDA2K (get the orginal unhacked ones from Club i-mate).
I removed files specific to that phone and basically left just the BlueTooth stack.
Recommend a HARD RESET before installing.
I've tested theses patches on a Sprint PPC-6601 (Blue Angle CDMA phone).
Do not do a restore of a backup before or after installing this because it may restore incompatible configuration files that may crash. Build 3100 is more robust against this problem.

Hey Bro
These two are for the Qtek 9090/Xda IIs or Xda II?

I am running 2.20CHS translated with Radio 1.18 and have been unable to get this stack to work. Has anyone tried it?

The ones I posted above are hacked by me to work on the CDMA version (Namely Sprint PPC-6601).
The ones referenced in this reply below are the original patches I started with that came from i-mate club. The offical phone name that the patches are for is "i-mate™ PDA2k" (GSM Slide out keyboard). I don't know how well they would work on the Qtek 9090.
Build 3500 http://www.blueridge.net/dereck/bt/PDA2k_Bluetooth_Fix.CAB
Build 3000 http://www.blueridge.net/dereck/bt/new/OEM_WWE_122_008.sa.CAB

Yes, good link but already bad quality with all bluetooth headset.
It's a shame.

It's a shame you don't give more details.
Which phone, which patch and what happened.
Works great on my phone.
I'm using the 3100 patch from the first post in this thread on a PPC-6601 with a HBH-300. Installed on top of a HARD RESET. That has Build 1.0.0.2200.
It's almost working perfect. Once in a great while if I go out of range for a long time I just toggle bluetooth and it reconnects immediately.
Dial Up Networking and Active Sync all work.
No static. No dropouts. Will go to sleep and wake up and still be connected.

I think that the "shame" was not for you but for imate as their patch don't solve all the issues. Maybe only a bad english ?

Tried on Himalaya_SE 2.06...
I'd merged the files from 2.02 and 2.06 and get a fairly stable handsfree, but I saw your files and got greedy... :twisted:
hmmm, it didn't work though. The installation freeze at splash screen after i cold reset the device.
I believe that there are still device specific entries in the cab files, but it's beyond me at this moment. :?

yes sorry. Just bad english because i am french
This website is wonderfull and a lot of information
But i bought a qtek 9090 (850 euros) and i realize that they sell some device with a lot of bug
Here is my qtek config

Patch fr bt 3000 or 3500 (it's the same : they are bugs both for headset quality)
Windows mobile 2003 SE 4.21.1088 build 14132
rom 1.12.20 FRE
radio rom 1.02.00
ext rom 1.12.146 FRA
Ericson 300 works good but it's too big for me. I am not robocop
But each headset i have tested with bt 3000 and 3500 becomes bad when you stay more than 1 metter from your device. There is scrashesssssssssss in the headset. You have to stay front of the device (in car for exemple) and it works perfectly.
But when i work the pda stay in my bag or other place then quality is horrible
That's why i said it's a shame from imate.
I think there is a defect on this device. I don't know what can i do to increase the audio quality when you stay far from the PDA.
If somebody can help me ????????
But i can see that everybody have the same problem and can't solve it.
Waiting for another ROM. HIHIHIHIHIHIHI they are mad to sell this device like this.
If somebody can find bt 3500 patch from imate in french i am very interested.
Thanks to everybody from xda developer : a great site

Note that I attached to the first post of this thread Build 3500 release 124 of the i-mate patch stripped down for use on PPC-6601 and VZ6600.

BT problems
Just installed the 3500 fix.
It improves slightly on the Jabra 250, but not enough to actually use it.
It Stabilized the connection between my Holux GR230 GPS and the Qtek 9090.
Hope there will be a better fix.
Try to look at the connection, problem with the Jabra is that it fluktuate from just right to zero every other second.
Nice to pay 800 Euro for something that do not work :shock:

I've added new patches to this the start of this thread.
They work primarily on PPC-6601. Read the attached notes.

Hi mswlogo,
Can you help me if you know which version works on a win2003se translated from chinees on himalaya?
Thanks

That phone is quite different.
I think some other folks are working trying to get this stack working on other phones like yours.
Most of the patches above have registry scripts run in them that will very likely not work on your phone.
The other patches assume you are already running late version BroadComm Stack.

I have HP hx4700 and the Widcomm version is 1.5.0 Build 2000
which one is newest?

That's a really good question.
I'm amazed to see BroadComm on 1.5 instead of WidComm.
What are the dates on the bluetooth files \windows\bt*.*
They are generally around 12/9/2004
It's hard to say what BroadComm and the venders are doing here.

Bluetooth stack on h6315
I just found a new bluetooth stack from:
http://www.ppcw.net/?itemid=2210#cmt9543
Installed on my t-mobile h6315. Device was previously inoperable with bluetooth headset. Device would go into power standby mode, and if bluetooth was running when it went to sleep, it would freeze requiring a soft reset. Now device wakes on power button, with bluetooth running, as it's supposed to. Device also wakes on incoming call, reconnects headset in less than 1 second, and allows me to answer call on the headset buttons. All other headset functions are working as designed, and sound quality seems good. My headset is plantronics 2500. Also, this stack adds a profile in the list for A2DP (??) high quality stereo headphones. Don't have any of these headphones, so don't know if this works on the h6315. Also, don't know if this is the same Broadcom/Widcomm stack you guys have been working with.
Installation is straightforward - put it on the device and tap it. Reset, delete existing device pairings, re-establish the device pairings, and you're ready to test.

All that patch is supposed to do is add two new bt profiles to the pda2k.
* High-Quality Audio support (A2DP)
* Keyboard support (HID)
I'm slightly suprised you got a performance gain out of it.

h6315
It's definately fixed the problems with my device hanging when it goes into standby with bluetooth running and the headset connected.
Now my question is should I install the build 3500 for the 6315 listed above? It appears to be a newer release than this. Any thoughts as to the differences? I'm having a hard time following from the thread as to all the other changes that are in this .cab, and why they are there? Can any one help summarize that?

Widcomm BT software

Hello:
my opinion of the BT software that comes on the XDAII is that it is not very good.
however the ipaq units have a great piece of software made by widcomm called bluetooth manager. The widcomm site is not very informative at all and the software is not available to download.
I have found that this software can be downloaded from here : http://www.compaq.com/support/files/handheldiPAQ/us/download/14376.html
this loads into my XDAII perfectly (with no complaints about my device not being an ipaq), but does not see the bluetooth radio...
Any ideas how to solve this, or is there any other decent BT managment software available for the XDAII.
PS - I am more than willing to pay for the software but widcomm do not seem to offer it for sale anywhere.
I think you got the link to the update for the Widcomm's BT - may be that is a reason why it does not work.
The reason I am saying that - I had installed my version of it on my I-Mate and it worked fine.
If you will search this forum for Widcomm - I am sure you will be able to find it, otherwise send me PM or e-mail and I will forward to you my copy of it.
Paul
Excellent. I found it on the forums already, have installed it fine. I keep getting intermittant BT radio not ready errors but I tink this is some other software that is trying to get to tha radio at the same time.
Thanks very much for your help.
I think i remmeber that error... It is interference with original BT on XDA.. Make sure that you clean your StartUp folder to prevent starting original BT

Toshiba bluetooth stack ROCKS...

I installed the Toshiba bluetooth stack on my I-Mate Jam and it ROCKS - it includes ALL the functionality/profiles missing in the MS stack!
...BUT...
It is unstable as hell (I have experienced all sort of "cosmetic" issues) and I am fairly sure this is due to the fact that both MS and Toshiba stacks try to use the same bluetooth hardware SIMULTANEOUSLY.
...SO...
has anyone figured how deinstall/reinstall the microsoft bluetooth stack on a Magician (I-Mate Jam, Qtek S-100, MDA Compact, XDA Mini)?

So, what "ROCKS" about it?
Always do full backup b4 installing sware.
it does what the MS BT stack does (serial port, headset, activesync), but also adds other profiles (pan, dun, obex, ftp, chat + others from memory)
i.e send files/chat with other mobile phone users, access bt pan, etc... though i am only interested in pan, chat and obex
when i fisrt played with it, i immediately saw why everyone whinges with the bt stack...
it's excellent and stable for me, didn't expierence any bugs...
dutty:
Did you get pan working ?
If so can you please let me know how?
Thanks,
Martin
I'm kinda interested ...
Can u please post a copy of that Toshiba Bluetooth stack u're using so we can all have a chance to have a look at it and maybe modify it to work on our phones
uh, just started the service, restarted the device and connected to it!
BUT, i also installed the toshiba BT stack on my workstation
I'm kinda interested ...
Can u please post a copy of that Toshiba Bluetooth stack u're using so we can all have a chance to have a look at it and maybe modify it to work on our phones
And just more thing ... How did u manage to get that bluetooth stack to run on xda devices since it keeps checking for external SD bluetooth cards and was not designed for internal bluetooth chips ?
Look in this thread:
http://forum.xda-developers.com/viewtopic.php?t=15382&highlight=
Thanks for the link ....... BUT !!
I was able to download the Toshiba BT Stack v5.01 but it won't seem to work on my xda !! Everytime I tap on Bluetooth Setting (from toshiba) It says the following ' An error occurred with the Bluetooth Card. Confirm that the card is working properly.
Both my MS Stack and Widcomm Stacks are disabled and don't conflict with this new Toshiba Stack.
I was wondering how the thread owner got this BT stack running on his xda ?
It works on my XDA Mini just fine. The only problem I'm having is that it won't stay resident when you power off the device.

RE
Sorry, another question.
In the event of a hard reset will my O2 XDA II restore the MS stack with whatever registry settings that were deleted in the process of installating the Toshiba bt stack? Will the Toshiba bt stack be totally removed in the evnet of a hard reset?
Thanks again
yes sir
Found 2 problems.
Cannot connect when call ring.. connect then call is fine.
Cannot Accept call with button on headset.
Any more Problems ???
Please post your problems ..
Hi
i´ve tested the toshiba bt software on my MDA-Compact but haven´t got very good results. First, after installation, it seems to work good with my Royaltek RBT 3000 (GPS), but after i´ve switched off the device while an active bt connection was established with my gps software, the bt-stack broks down and the whole systems seems to be unstable. Even after a softreset the bt-software from toshiba says that they didnt recognize any bt hardware.
Now i am trying to deinstall the bt-soft and can recommend everybody who wants to test to make an backup before ;-)
I think that the software from toshiba could work, when the ms-bt-stack would be completly changed with the toshiba-stack, but doesnt work without problems when both bt-stacks are on the system.

Bluesoleil BT stack + manager, stable and more profiles

I found out about this BT stack driver through a thread regarding the toshiba BT stack driver, so i thought: other driver, other thread :wink:
Original thread here: http://forum.xda-developers.com/viewtopic.php?t=15604
Download BlueSoleil CE here: http://ivtcorporation.com/download/BlueSoleil_Download.php#bluesoleilforce
Credits for finding this BT stack go to: rdkay
It has a lot more profiles then the standard MS stack.
Occording to their web site, supported profiles are:
PAN, OPP, SYNC, LAP, DUN, FTP, FAX, HID, SPP, HCRP, BIP, Headset, AV
The manager that comes along with it, is also a lot better then the standard one, more options, more playing around
I played around with it for a while, and i think it is rock sollid. Although I have only tested the SPP profile (with BT GPS). It never crashed, not even on suspend & resume. The radio will be deactivated during suspend though. For me this is perfect, because it will save battery life.
On resume, it will be automatically reactivated.
Installation procedure:
- Download Bluesoleil CE: http://www.bluesoleil.com/update/index.asp
- Before install, delete these reg keys:
[HKEY_LOCAL_MACHINE\Services\BTIcon]
[HKEY_LOCAL_MACHINE\SOFTWARE\microsoft\bluetooth]
- Reboot PPC
- Install Bluesoleil CE
- During setup on PPC select Manual -> USB driver, then let setup reboot
This next step is optional, do this only when you have troubles with your GPRS connection (a newly installed network driver prevents it from operating properly on my device) Delete following reg keys:
[HKEY_LOCAL_MACHINE\Comm\BTNIC]
[HKEY_LOCAL_MACHINE\Comm\BTNIC1]
Reboot once more
Finished! enjoy
Sorry to spoil the celebrations, but I have already tried this stack. Indeed it works fine - except for the dirty details mentioned on the download page:
"Note: If your Bluetooth Hardware device (such as USB Dongle) is not licensed by IVT for using with BlueSoleil, any BlueSoleil version downloaded here can only be used as evaluation version, only 5M data can be transfered through Bluetooth link in evaluation version."
Unfortunately this is true - it shuts down the connection after transfer of 5Mb and after some time (a couple of weeks?) it no longer functions at all. I would be happy to buy the full version of this Bluetooth stack for my MDA Compact, but sadly the company does not seem willing to sell it.

WOW :lol:
is this the solution i've been looking for, for my Parrot CK3000 carkit?
Just 3 questions before i will try this one tonight:
- Is it un-installable? (cause you change the regkeys)
- You had no problems with ActiveSync? Cause i would really feel bad loosing that!
- If it works on the Magican, it should also work on my dutch MDA Compact (T-Mobile, but ROM upgraded to 1.06, radio 1.05) right?

- You should make a backup of the reg keys you delete, only then it will be reversible.
- No problems with activesync of any kind.
- I have radio version 1.05 myself, so for that it should work. For ROM however, I have version 1.03, since too many ppl were complaining about bugs & instability.
--------
Also, I have written an email to their company, asking if they would sell it, and howmuch it would cost. Lets see if we'd get some awnser. I could live with a 60 days limit (i would reinstall my PPC long before that), but a 5 meg limit....... :?
So, which devices are licensed?
Found a configuration file, so we can do some additional tinkering :wink:
File: \Windows\bttl.ini
The following file has obviously to do with the license for application.
I suspect, that if we might be successfull with tickering in this file, we might get a full blown version. But lets first wait if I get awnsers from the company if they'd sell it; I prefer a legal version.
License File: \Windows\IVTLicConf.dat
Also, an additional ini file, that appears to be the same (?) as my first reported bttl.ini : \Windows\BTDynamicConfig.ini
for me it is working perfect. thx a lot heimiko.
Anybody tried this stuck with BT headsets...?...I would like to know if it works with SE HBH-660 or some other BT headset supporting Caller ID...

Primoz

Xlephant: I was really looking for a good stack for my ck3000 also! Can you tell me if it allows me to upload the phone numbers to my carkit also and use the voicedialing app inside the ck3000? (Cause with my old Sony Ericsson T610 I could)
:shock:
Thomas
don't know much about the ck3000. but i have no problems to upload the phonebook with this stack. but i was also be able to upload it with the ms stack(the ck3300 works perfect with the ms stack). i swaped the stack only because of the PAN profil.
I don't understand what everyone is getting excited about. If you cannot buy it, then it is useless to me.
Regards,
William
thats true but i think there should be a way to buy it or to reset the 5mb limit.

Does this stack allow voice dialing with a bluetooth headset ?
Thanks in advance...

It should, provided you have a dialer app that does. And as the bluetooth is switched off in standby you would have to initiate the dial-up from the device, not from the headset.
Radio issue
What do you mean by the radio will be deactivated during suspend? The Bluetooth radio or won't I be able to recieve any incomming calls on my MDA Compact?
Has anyone actually experienced any of the mentioned limitations, i.e. 5 MB limit, etc.?
Cheers for the reply!

HP iPAQ Bluetooth Stereo Headphones Problem!

Hi All. i've got a qtek 9000 and i can't use my bt headphones.
I bought this one with the ipaq and than i succed using it also with my qtek 9090
right now i can't with the new 9000 and i have no idea how to do it
please can someone help me?
Please be more specific as to where the problem is. You say you got it working on the 9090 but not on the 9000. Exactly what part of the pairing process does the difference come out?
Ops, i miss it!
I installed on the 9090 an audio driver that add a new voice in the bt connection manager.
The high quality stereo headphones. This driver couldn't be installed on the new wm5 because was designed for pocket pc 2003
so rightnow i can pair the device but no service is offered when i try to discover device services.
So even if i have paired the device i can't use it because no service is found.
i hope i've explained the problem
tnk u 4 your support

You mean it cannot be paired without running a particular software? Yikes... So when you put the Bluetooth headset to discoverable mode, then try detecting it from the Universal, it sees it but there are just no services available, am I right?
So it seems that the one at fault is the Bluetooth stack installed in the Universal... In that case, I cannot help you... SOrry
The Universal does not support A2DP or what HP calls High Quality Stereo, as such it does not support your headphones. A2DP is suppose to be part of what is included in the MSFP update but i-mate has chosen not to include it. Until someone releases A2DP support your headphones will not work. Now if you happen to read German I understand their is a German ROM that supports this feature.
Otherwise it just a question of waiting till someone releases this update, if they do.
i think that is the stack but the question is:
the 9090 doesn't support the high quality too but installing the driver things changes so i won't belive that thare isn't a driver for the 9000
i tried to find something from Widcom (i hope is the right way to write!) nut i dind't find anythink
so i hope that someone can help me because i've payed 120€ the headset and i will love to continue using it!

Cracking sound with Bluetooth headset

I got my S200 back from a repair and it was also upgraded form G3 to G4.
Everything seems to work fine, except my Jabra BT500 head set. After pairing with my S200 I got a very cracking sound.
So I checked my Jabra with another mobile phone and it worked very well. I checked another head set with my S200 and again a cracking sound.
Does anybody knows how to solve this or do I have to return my S200 again for repair?
Hi, I have excatly the same problem, it also occurs with the bluetoothof my car...anyone can help us?
I have returned my S200 to QTEK today in order to have it repaired (again).
I have tested it (in my car) with 2 other Bluetooth headsets and there was no problem. There was also no problem when I tested my own headset on another phone. So this proves that my S200 has some kind of defect.
The sound is very crappy ?
Or is the soud quite ok, but experiencing high frequency glitches, kind of metallic parasits?
Because in that case, there is nothing to do, It's due to the MS bleutooth stack which has a very poor encoding librairy... and since there is no widcomm stack for S200 (and some other qtek too, a lot of people is yet trying to malke it work), then evey bleutooth headset will have bad sound in A2DP with the S200 :'(
One of the main reasons why I want to change for a widcomm stacked pocketPC (shame on MS!!!!!!!!!!)
For me, the quality is very bad. At the beginig I use it only on my car and it was working perfectly, since I try to connect to the bluetooth headset or to my computer the sounds became very very crappy. I have Dopo ROM, which rom do you have? what ROM do you advise? Thank you
I have tried the LVSW, Jester and shipped ROMS and all these ROMS have the same problem. So I think that it is not related to the ROM but due to bad hardware components.
it's strange because it was working for me before I use other bluetooth device. I will try to upgrade the rom to the official QTEK ROM
I have the same problem. As if the bluetooth signal were cut per moment.
it's not linked to roms, but to bluetooth stack, so since the bt stack is updated (but I doubt it), changing roms won't help
I could fix it, I update the ROM, delete all pairaing on my cars... I change the "hsotname" of my QTEK on "settings - Owner information" I recreate the pair and it works fine on my car, now crappy sound anymore. Just to test it again, I try to pair my "fujitsu laptop" to my qtek, since I did it, the sound is again very crappy. So I will flash again and pair it only with my car. If I return it to Qtek it takes 1 months... If someone can fix this that would be great.
