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 pairing issue

Hi all,
i am runing my trinity with WM6 and AX3l's rom. my issue is that i cant connect to my car stereo which is a pioneer DEH-P55. My trinity see's the stereo and gives the option for hands free but the stereo cant detect the trinity. my device is visible to others but the stereo wont pick it up. Any suggestions for a fix on this would be appreciated.
thanks

maybe you have to push a button on your radio to activate first time pairing, that was the solution for my bluetooth headset.
(pairing from both sides)
just a suggestion, maybe it helps.

Try the Jetware bluetooth extension it has a 30 day trial and worked for my Alpine headunit its at http://www.jetwaremobile.com/

Thanks for the replies, but still no luck. I can pair other phones to the stereo but not this. Are there any settings that i may need to activate on the device that i am missing? its abit infuriating as i need to get this up and running as soon as.

activated "receive all incoming beams" ? its in settings/connections/beam

its already activated stormyb but thanks again for helping.

I always had problems using bt and irda...
I never succeed send/receive any file using my pc (my pc irda always worked fine with others devices). Beam enabled on commManager and on settings "receive all incoming beams".
When I try to connect (pair) using (htc) BT I get this error: the connection failed or the passcode is incorrect...
---
One time I tried to send a file to a nokia phone and I needed 30 min to succeed: restart phone, restart BT, restart beam, restart phone, restart nokia, restart BT, restart, restart, ....
Now I'm using the radio 1.46.00.11, rom eLiAs2.11wwe (before I was radio 1.38 and udk rom) and when I pair from htc, on pc I don't receive the pin request. If I pair from pc, I see the request for pin no htc but when I type it: "the connection failed or the passcode is incorrect".
Only one time I was succeed pair (and saved on device list), I typed 3 times the pin code, but after I can't transfer files...
From pc, I see the htc on the device list, if I try the ftp service, htc ask me: "xxx wants to connect with your device using bluetooth. Do you want to add XXX to your device list?" I answer yes but when I insert the pin, the pc give to me this error: "error establishing the connection"
If i try the voice gateway, after type the pin on htc I get this error on pc:
"the remote device closed the connection"
Using this last rom, when I try beam a file, I can't see my pc irda (using the udk rom I can to see but without success), I only see my pc BT but always "failed" the connection.
Nobody has the same problem?!

What bluetooth comms are you using, windows or Widcomm's?
I installed widcomm onto my laptop as I was suffering the same problems as you mention and I couild not get a bluetooth serial port setup either, once installed and restarted the pc then I just powered up both BT's and set the phone to visable and the laptop found it straight away with all the services and could setup the serial port.
I seem to recall there are numerous problems with most BT's when using the default windows drivers etc..
HTH's

hi, I'm using widcomm...
I didn't test again a bt headphone, but I have problems trying to connect to a nokia phone for example (n95, n73).
The irda never works... I tried too with a nokia phone and a remote control software for wm6... nothing...

All ok using headset BT...
I installed blueSoleil BT driver and now it is ok.

same ppc, same rom, same problem with my bt bury in the car and with other ppl's triyng to bt connect to my ppc. i can "see" them they can "see" me but there is no transmission TO me. I can send.
i am using the bt phone (bury) but onlt when I initiate the connection. i think it's a rom bug.

Widcomm+BT GPS+A2DP equal weird problem

Hello,
I'm new here, but I recently got a Axim X51v. I decided to immediately (after playing around with it for a while) to flash it to the WM6 Football ROM. It works well and so far that part I haven't found any problems with.
Everyone recommends the Widcomm BT Stack so I installed it and have very odd results. With Widcomm I am able to use A2DP well and the pairing and setup is easy and great. Somehow it cripples my ability to use my BT GPS Receiver (Holux 236). TomTom 6 will not detect the GPS signal at all, but the GPS reciever is paired and everything.
If I don't use Widcomm then A2DP does not work. I use a pair of Kyocera BT headphones and it will pair with the normal BT setup and it is recognized as a headset. When I try to use it with Windows Media I will hear the first second and then nothing. The player continues to play, but I just hear dead air. The GPS receiver works well when Widcomm isn't installed. It automatically detects it and TomTom gets the signal to work.
I really like the Widcomm BT Stack, but I kind of need the GPS. I've read some articles on different setups, but I can't find many on GPS problems and if I find some they don't have any answers. If you have any advice on what I could then please post. From my search I haven't found anything here either, but if I'm wrong then please point me to the right direction.

Downgrade BT stack?

Hi there,
I have HTC Universal and Dell BH-200 stereo bluetooth headset.
Situation:
- WM5 ROM (for example newest KDSkamal) - after a bit of fiddling A2DP works, also HS profile is working
- WM6 ROM (for example Tomal's 8.5, 8.2) - A2DP works after fiddling, unfortunately HS profile's not working - headset turns itself off after 5-10 second of call, during which nothing can be heard
- WM6 ROM + Broadcomm stack - A2DP works flawlessly, HS doesn't.
From what I know, no WM6 device works correctly with Dell BH-200. It's interesting though, that WM5 devices appear to work. Also, I've read here that Broadcomm stack doesn't support HS profile, so out of luck here.
Now, I was trying to just overwrite WM6 BT stack dll's with ones taken from WM5, but it didn't work either - maybe that's because I was doing it rather randomly, without solid knowledge of the matter.
As I see many skilled hackers here, maybe someone would take his/hers time to help me out a bit and figure what has to be done to have working WM5 BT stack on WM6 device?

So I've done some primitive hacking, here are the results. I've been using files extracted from newest T-Mobile WM5 ROM, on my device there is Tomal's 8.5.
First, I just used every bth* dll file I could find and overwritten ones in Windows folder:
bthutil.dll
bthusb.dll
bthuniv.dll
bthuart.dll
bthsc.dll
bthlink.dll
bthidsvc.dll
bthhid.dll
bthcsr.dll
bthasplugin.dll
bthamb.dll
BthAGPhonebook.dll
btdrt.dll
btd.dll
btagsvc.dll
btagext.dll
After this, Uni wasn't even able to turn on GSM - no idea why.
Then I tried with just
BluetoothSetting.dll
btagsvc.dll
btagext.dll
Much better stereo - it works now, before there were lots of noise; also, headphones no longer switch off when receiving phone call; unfortunately, no handsfree support.
Will try more...

OK, false alarm - just found out that I need to force pairing from the headset (using Play/Pause button) and the A2DP works, even without replacing btag[svc|ext].dll. After this sequence A2DP works, but Handsfree doesn't (but at least it doesn't turn off the headphones)

maybe some reason
i have special infomration ..
I have TOmals ROM and i found this ...
if i will turn first bluetooth on my Uni and then i switch on my headpohones - everything works great. Also in my car parrot works perfect - A2DP and also i HF ...
If i will start bluetooth after bluetooth in car or headphones ... then A2DP makes sound pause ... and HF is not so clearly as usually ...
i dont know why .. but it works like this ...so try to switch BT on pohoen first and thne accesorries and youll see ...
Bye

I tried that, but to no avail.
But now the fun part started: if I extract files from Tomal's ROM nbf, they are in different size that the ones _from the same ROM_, just installed on Uni. Even better, if I overwrite installed ones with extracted ones, radio, SD, camera and so on stops working. I wonder where is connection between SD, camera, USB connection and bluetooth...

Now I replaced only btagext.dll (however, I think that all this replacing effects only in disabling replaced dlls...) and best thing I achieved is that
- A2DP works almost flawlessly with Dell BH200 (if I keep correct order of switching devices on)
- HFP works with second device, Sony Ericsson HBH-PV708 (had to disable HFP profile in BH200)
Audio switches when receiving phone call.
Obviously, that's not the best solution (far from it), but it's at least something...

[Q] How do you connect Evo to Windows 7 via Bluetooth?

Hi, I'm trying to connect my Evo to my Windows 7 laptop so I can use the laptop as a hands-free (better speakers and mic).
It was really easy to pair the Evo, but after that there are no options for connecting?
If you press and hold the computer's name in Bluetooth Settings, the only option is give you is to Unpair. Unless my car and BT handset, where it shows 3 selections (Connect, Unpair, Options).
Has anyone been able to successful pair AND CONNECT their Evo/Android phone to Windows 7?

I got mine to connect once, did it on the laptop side after making phone visible, just transfered some files, doubt it will do what you want without a program on laptop with those drivers that will let it, I doubt it could native

Thanks, yea, on the PC side, there isn't any option to actually connect it?
I can see my phone and it has all the services checked but there's no actual option to connect. Not sure if this is a Win7 or Android issue?

It's the default Windows 7 bluetooth driver; it's not very compatible with smartphones or anything other than some OBEX, headsets, A2DP, etc.
Third-party Bluetooth drivers work OK though, like Blue Soleil.

thanks, that sucks.
hopefully, M$ will improve their bluetooth stack to work better with mobile now that winMo 7 is out.
