Creative CB2530

I wanted to let everyone know that these headphones, although they seem to support some sort of A2DP (Can talk to them from a laptop supporting A2DP), they will not talk to windows Mobile 5 with A2DP. I have the Cingular 8125 (aka HTC Wizard), with the A2DP additions loaded on it and the 2.17 firmware. I have my wizard talking A2DP to Motorola headphones, and to a Scosche A2DP car receiver. They both work great, and even though the wizard will see the creative headphones (I have 2 of them, so I know it's not 1 defective set), and will see the "Wireless Stereo", when I try and connect the wireless stereo, I don't get the Headphones with the note icon like I do with the other A2DP devices.
FYI for anyone else considering the Creative CB2530

I can use them with my Trinity, but it was a little tricky.
The problem was with the Microsoft Bluetooth Stack, it tries to establish a secure connection when it is not required. Worked fine with my laptop(widcomm) and previous pocket pc(iPAQ H6365-widcomm) but the latter was unusable due to the lack of bandwidth.
I'm not sure if this is really the solution
but I believe you must add the CB2530 without entering a password first, the headphones will try to connect right after confirmation of the services we want to use(wireless stereo in this case),
"the device cb2530 is trying to connect... yes/no" - something like that
the pocket pc will request for a pin, enter 0000 and wait, the phones will disappear from the paired devices list, try again, this time insert the pin 0000 right after selecting the CB2530 from the found devices list and voilà, an A2DP connection will be established.
It's a little weird tough, the system sounds sound choppy, even with jointstereo off and increased bitpool(512 lol), PocketPlayer doesn't stream the audio through A2DP, and media player does it right and the sound quality is nice(only a few other skips but overall pretty nice and the original transmitter wasn't perfect either), but maybe because of the load of audio conversion on the CPU the whole UI gets sluggish, odd.(or maybe it's the bitpool value I used)
It works.

BLUETOOTH STACK - please please help me

I have read every post about MS bluetooth stack vs widcomm etc....
I know someone can build a cab file that will uninstall the MS one and replace with the newest widcomm stack.
I LOVE my universal but I carry TWO phones with me because the universal's connection via bluetooth is not PERFECT for phone calls like the blackberry (oh i fking hate the blackberry for everything else).
I REALLY REALLY REALLY want to use only my Universal but the static on bluetooth KILLS me because I am on the phone 10 hours a day.
PLEASE please help me. Fish

This file fix Blue Tooth

Bluetooth stack
I would second Fish's comments about the Univerasl and the Bluetooth stack. I have bluetooth in my car and it is great WHEN it works. When it doesn't work it takes a lot of tinkering to get the car to recognize the phone again. I'm of course not sure if the issue is on the Universal side, but Bluetooth turns it self off, so there is some kind of problem. I have tried different radios, currently 1.13 (tried 1.14 as well, but went back). I'm very interested in finding a solution (not using two phones), can you please provide some detail on what the CAB file does to Bluetooth?
Thanks,
Sven

What exactly does this file fix/change ?
I've just installed the WM6 crossbow helmi_c version
do I still need this file ?

This is a Stack changer to change from MS BT stack to Cambridge Silicon Radio BT stack. Originally developed for Dell AXIM (about what I've found). Seems to work fine there, but need to uninstall/reinstall after every soft-reset because of a volume lock bug.

I'd rather go with the widecomm BT

I installed the Hermes Widcomm BT stack on my Universal. Sound is great, but the rest is troublesome. We need a developer to fix the code for us so it works on the UNiversal .
Check my thread in UNiversal/accessories. Or move that thread over here please!

Tried out BT Stack change for Hermes patch/program.
TEST RESULTS ON UNIVERSAL WITH WM6 (Midget aka Helmi unreleased)
Sound IS great. But other than that, this program does not work very well on my device. Of course this is designed for Hermes but I gave it a shot.
Issues:
1:
Screen flickers (only when this BT is turned on).
Flickers really bad and unable to use device.
Fix: set the device to standby (power button) and wake it up again. Flickering gone
2:
Once BT is deactivated for a few minutes I can't start it again.
Fix: No fix found yet. Only a Soft-reset and directly activate BT works.
3:
I can't use my GSM/UMTS connection anymore. Trying endlessly. Even after soft-reset's I can't connect. WiFi works fine though.
Fix: No fix found yet.
4:
Unable to uninstall this program. Tried several times. I get to the "Soft Reset Device Yes/Cancel". I soft reset, program still there and working.
5:
Hard-Reset, complete setup with WAP, MMS, MAIL etc.
Installed Widcomm BT Stack again.
Soft-reset:
Screen flickering (fix)
No 3G/UMTS connection avalible anymore. Even when BT stack is completly shut down.
We need a specific one for our Universal. Who's up to fixing this for us?
KEEPING this post updated.

Quoted from my A2DP/AVRCP thread in accessories.

Even with the new WM6 roms - I have tried ALLLLLLLLLL of them the bluetooth phone quality sucks.
I am using the new Pdaviet 2.0.03 (something like that) and i have tried
THREE different headsets
Jabra BT250v
Jabra BT500
Jabra BT500v
All have the same crackly sound issue. But with my blackberry (ass phone, i HATE it) the sound is PERFECT.
I am soooooooooooooooooooooooooooooooooooooo tired of carrying two phones with me - i can not live without my memory (or i mean the universal, which i use as my personal assistant). But my clients can not live with the quality of the phone call connection. Now if I do not use my bluetooth and hold the GIANT universal up to my head (kinda like a military field radio) then the clarity of the call is great.
It is the Bluetooth stack i am 100% sure of it.
OMG Helmi_c let me have your widcomm stack PLEASE I will even pay you for it.

Thanks for the info
I changed the channel in the registry of the device to channel 5 as suggested on that webpage. It was the same quality. I then tried a few other channels and the same results - connection quality still staticy.
Thank you very much for trying to help me though. Fish

I'm also worried with the same issue, because I've exactly the same problem. But I don't think only altering of BT stack should fix the problem. My understanding is, something is also to be done in radio (rom) side itself. Because I was using a different radio rom last year at about May or June and my BT headset worked perfect. But I can't remember now about what build that was, because later on I've updated my radio to few other releases.

Radio rom has NOTHING to do with the Bluetooth or Wifi - It's ONLY the firmware for the GSM chip.

We know the MS BT stack is crappy. I found out today that Helmi_c is developing one. But, still, this thread should be more about how to resolve the BT stack change (or just shut it until our friend Helmi_c finishes his school stuff and gets back to being the ROM-N3rd in need of more RAM that we all love so much) than bringing up more issues about the MS BT stack.
Thanks.

guys,tried almost all roms on my universal,some of them works a few days,after 3 months i flashed with the good old official rom,better and stable than all
anyway,the only reason for this waste of time was this a2dp issue,being not able to listen music to my motorokr(tested with 2 laptops and 2 htc,working great)
so i think is just some kind of incompatibility motorokr-universal(yes,i try all the a2dp hacks/registry editing found here

WM6, GPS, A2DP skipping - is there a definitive answer?

After much searching and Googling, I'm a bit stumped.
I'm currently running VP3G's 2.0.1h variant of the WM6 ROMs, and A2DP works beautifully. So does CoPilot / MSN Live Search / Google Earth with Bluetooth GPS. But together? Skip goes the audio.
Some playing with the BitPool setting got me more or less audio before the skips. The BlueTooth GPS is the one that comes with the CoPilot bundle, SirfSTAR III, running at 4800 baud. Fairly standard fare. The A2DP headset is the Sony Ericsson HBH-DS970 headphones. Ideally, I'd like to be able to use it for satnav - you've guessed it - via the bluetooth headphones.
I haven't tried installing the Widcomm stack yet, although that's next on my list. It'd just be nice to do it "natively" with the WM6 bluetooth drivers if possible.
Thanks in advance!

The Hermes has a hard enough time just with A2DP, co-existing with a BT GPS receiver will be really pushing the device's capabilities. You can try installing Sleuth255's A2DPFix v1.0 which does a really good job of fixing A2DP issues in general, but I suspect that you may be asking too much from our poor little devices...
John

Well, installing the Widcomm stack solved it hands down - whilst it seemed to use a little more CPU, it worked fine with the bluetooth GPS and the bluetooth audio, with the satnav application broadcasting audio via the headset.
I'll try the A2DP fix, and see if it does any good with the MS stack. Still, at least I've got a way around the problem now!

Interesting! I have always considered the Widcomm stack to be miles better than the M$ one (even though M$ has made quite some improvement recently), but just never had enough time to really play around with it to get it working on my TyTN. There was an effort started late last year to raise $500 for the first person to release a working version of the stack, but unfortunately it fizzled.
This might be enough to get me to try again. I am going on vacation for two weeks starting Sunday, this would be a good project for a rainy day -- I am going camping, it always rains when you're camping!!
John

Oh, absolutely, it wouldn't be a camping trip if it wasn't pouring down
After playing around with it some more (using the 0.3 version from the thread), it seems a bit flakey, sometimes failing to update properly, but I think that's more down to CoPilot than the stack - MSN Live Search and Google Maps seemed to work just fine when I was listening to my music. Nothing fancy on the music score either, just plain old Windows Media Player. A lower CPU usage program might help the satnav program - I'll try some alternatives shortly.
The A2DP fix made no difference at all, although I suspect that's mainly for the awful MS implementation on WM5. I haven't really noticed all that much difference in sound quality between the two stacks, although some people rave about the Widcomm, but maybe I'm just not as attuned as some people
There's no doubt that the Widcomm stack is better than the MS one, although it's not without it's apparent issues of course. I tend to use the MS one for general usage and the Widcomm if I need to do more than one bluetooth thing at once. Seems to work for now, although I need to put it in more heavy testing.
Both stacks give the odd skip, but I tend to think that may well be down to how much CPU usage I'm pushing out of the poor little thing
The problem with the Widcomm stack being ported properly was that it wasn't really organised all that well. If someone steps up to the podium, I'm pretty certain people will pay for the functionality. It's just finding someone with the skills and time to do it!
Give it a try, although beware of the potential caveats - reading up on the thread is recommended.

TP2 Vodafone UK Bluetooth

Sorry if this has been asked before but could not find anything in the forums.
I have a Vodafone TP2 and even though the bluetooth connects and stays connected to my car bluetooth or the Vodafone free headset that came with the phone, I get no sound through bluetooth during calls. The BT initiates cals fine but if I connect a call in or out I have to disconnect the BT and use the phone.
Any ideas? I have hard reset twice now and it seems to work once then not again.

youre no the only one, ive had the same problem with the vodafone model. Help would be awesome, please...

According to Vodafone my warranty would be voided if I put the stock HTC rom on my TP2, but if it fixes the radio and gets rid of the colour scheme I would do it, but I seem to remember reading somwhere that the phone would be bricked if the HTC rom upgrade was attempted? I can't see why that would be, any input appreciated!

Apparently this is a known problem.
HTC have already posted an upgrade to their site but as yet Vodafone have not done the same although they will upgrade the software through their own repair service.
Don't hold you breath for the VF fix.

I spent ages on the phone to Vodafone last night and they are swapping the phone out tomorrow, I'll update with the (lack of) bluetooth news...

I ended up with a refurbished fone when i sent my tp1 to vodafone for a firmware upgrade

Luckily mine is under a week old so I get a direct replacement...
Hopefully!

I do have a bluetooth problem as well... When connected to my car bluetooth, It will drop an incoming call immediately it registers... but i can make a call through the bluetooth fine!
Hopefuly this can be fixed!

In The Bluetooth settings / Advanced / Audio try ticking the "play sounds on remote device" it might help you.
Gordon

That wasn't the issue, I had already tried that theory. Still, new phone arriving today...

ok, new phone, same issue. excpet it does work on my BT headset but not my car.
So...
Can anyone tell me definitively, am I able to flash my Vodafone TP2 with the new HTC rom from their website, and am I able to backup up the existing rom at all?

I'd like to know the answer to this too, but it seems our Voda TP2s are few and far between in the xda-dev world!!

So I have HardSPL'd my device and wanted to put the HTC rom on, but I can't download it from HTC due to my serial number!

I'm sure the ROM has been posted on here somewhere, if not there is a thread somewhere with valid EUR serial numvers that you can use

Ah yes, I found the ROM and flashed happily away!
I am now running the HTC ROM and although I have not yet connected to my car bluetooth, I am 100% happier with the interface!
I'm not much for screenshots, but here is one of my sync centre showing the "old" Vodafone partnership and the new one:

I wonder if this is what is causing my problems. I have a vodafone TP2 - I bought it about a month ago. It works absolutely fine with a Jabra BT500 headset.
However, I have a handsfree car kit that is part of an Alpine stereo in the car. Basically it's a Parrot unit that is incorporated into the firmware of the stereo. It works fine for making outgoing calls and connects ok, but as soon as I receive an incoming call it gets immediately cut off and diverted to my answering service.
Apparently Alpine are releasing new firmware for the stereo next month that can be flashed onto the unit so I may see if that fixes it. Otherwise I'm not sure what to do!

In the market for a new phone and have a Bluetooth question

Hi all, I'm in the market for a new phone, though, that's not what I want to ask. I'm interested in the bluetooth functionality.
What I'd like to know is for all you Xiaomi Mi 6 owners out there - Are you able to have multiple bluetooth devices connected at the same time, just like the S8+? And I'm not talking about dual audio.
To elaborate on the question. I have the leeco le pro 3 and normally have my bluetooth headset everyday. When I jump in my car, the phone connected to the bluetooth car which is expected, however, the phone completely disconnects the bluetooth headset. I just tested out a friends galaxy s8+ and was able to have both bluetooth devices connected at the same time, and "hot swap" between the 2. I'm not sure if this is the result of Apt X technology, android OS version or even the mfr's ROM config.
Can the Mi 6 do that?

Yep, I can do that on my Mi6 - AICP 13.1
The phone is contently connected to my watch (Amazfit pace).
and it connects to my headphones seamlessly.
although i haven't tested 2 BT headset at the same time.
I can test it tonight if it helps

Thank you, yes can you please test it with 2 audio and/or phone channels. In my case, I have a bluetooth car receiver and a bluetooth headset that I want to have connected at the same time, so I can switch between them. I have an old phone that doesn't allow 2 of the same type (phone/audio) channel streams to be connected at the same time. I know that most phones can't stream to 2 at the same time, but I want them to stay connected so I can hot swap.
Below is how my Bluetooth looks when I connect to 2 devices of the same channel. I can't have both phone and audio on both bluetooth devices *connected* at the same time.

Well, I've played with it a little....
As you can see in the attached picture, I have my Amazfit Pace Smartwatch connected.
JBL BT headset for music
And Sena for calls.
You have to set profiles for each one; you can have two BT connections for music or calls, you have to pick what goes where.
But at a click of a button I can switch between them (is this what you call "hot swap"?)
As far as I know, both the Samsung and the Xiaomi have BT 5.0
So I don't think it's a hardware limitation.
It's also worth mentioning that I'm using a custom rom:

It's 100% software limitation, just like I said earlier
both SGS8+ and the MI6 have BT 5.0 (and the Pixel2 and OPO5 and others)

I guess it's a matter of time and ambition from our devs.
BTW, if it help, android P should bring us the ability to connect to 5 devices!

[*]You have to set profiles for each one; you can have two BT connections for music or calls, you have to pick what goes where.
Yeah that's what I have to do now, because when I connect the second device... the previous device will get completely disconnected from the phone. I have to go in an manually choose which profile goes on what device to have both connected, but that doesn't help me since I can't push (for instance) the answer button and have the bluetooth transfer the call or media over to the specified BT device.
[*]But at a click of a button I can switch between them (is this what you call "hot swap"?)
Do you mean the click of a physical button?? Yes ! that's what I mean as hot swap. When I press a button on one headset, I want the active call or media to be transferred to it automatically. Instead of now I am having to go in and switch profiles, or even disconnect one of the two devices.
[*]So I don't think it's a hardware limitation.
Yeah I am starting to think it's software implemented like you said. Do you think otherwise now?

It has been a mini rollercoaster.
To make a long story short:
Right now, with Android 8.1
The mi6 operates just like your 'old' phone.
Not like the s8.
Why is this like this? Is it hardware? Is it software?
I have no idea.
As of right now, I found that a ZTE axon m is supposed the have the same "dual audio" as the s8.
If it's really the case, then it should be a matter of software.
I've downloaded the axon m kernel and in the few days will poke around when I'll have a time away from work.
I've also heard that the LG v30 have dual audio, but haven't looked into it.
If you need to buy a new phone NOW, and you MUST have that ability, then the MI6 is a no go.
This could be a nice project, but like everything here on XDA...I can't give an ETA.

Thanks for the help! For the sake of being clear.... "dual audio" is not the same thing as having multiple Bluetooth devices *connected* simultaneously. "Dual audio" is what Samsung named the feature which streams audio to 2 devices simultaneously. I'm not sure if this is a Samsung thing or not. hopefully you understood what I meant earlier, which it seemed like you did . I don't need audio played on both. I just want to swap between the 2 with the push of a button on the device itself.
The Dual Audio feature has been released with the Samsung Galaxy S8, S8+ & Note8. When two devices are connected via Bluetooth at the same time, the Dual audio feature allows the user to play sound on both devices.

I planned on buying the new Xiaomi Mi 7 when it comes out, but the rumored specs show that it has the exact something Bluetooth features as the previous gen which is why I asked here
Thanks again.
