The problem is connecting Nokia 6230i and IBM Thinkpad T43P over bluetooth using Nokia PCSuite (latest) on WinXP SP2.

I tried following:
PCSuite -> Get Connected -> wizard it finds 6230i -> Next asks for passcode default 123 -> Next -> phone asks to combine? -> Yes -> I enter password 123 -> Nokia PCSuite says "You have now the following connection available: Nokia 6320i bluetooth" -> I click Finish.

during the last screen I see taskbar icon Bluetooth connected, it appears for a few seconds and then becomes Bluetooth disconnected.

why does it disconnect by itself?
how to connect Nokia 6230i and IBM Thinkpad T43P ?

thank you.

I'm experiencing the very same behavior on a T43p running xp pro sp2.

Unable to reach the original poster, so has anyone resolved this and able to share the solution?? Appreciate any advice. thanks. /b.

There can be several reasons why bluetooth disconnects. If you have any other things that works on the same hertz like WLAN, Halogen lamps etc. it can disturb the connection.

When having SP2 och Windows XP installed the built-in bluetooth driver from Microsoft also sometimes conflicts with the driver from your computer manufacturer. There are several troubleshoot guides how to resolve this issue on Microsofts homepage.

Since you have the same computer and it acts the same way it might also be something related to the computer itself (or the drivers used). Which bluetooth stack are being used? Compatible Bluetooth stacks and versions with Nokia PC Suite are these:

Microsoft Windows XP Bluetooth
WIDCOMM BTW 1.4
WIDCOMM BTW 3.0
Toshiba Bluetooth 3.0x
IVT BlueSoleil Bluetooth stack for Windows XP/2000

I have this same problem (with Nokia 6630), and it looks like Thinkpad T43 and similar models are using Broadcom bluetooth stack -- so, as it is not supported, it creates compatibility issues between Thinkpads and Nokia PC Suite. I have tried multiple configurations, and now I can use Bluetooth to manage my phone memory, do calendar sync etc, but not connect to Internet. My bluetooth is version Broadcom 5.1.2535.0 (IBM Integrated Bluetooth IV).

Hm. The Broadcom driver appears to be known as BTW 4.0, so it is probably a new version of the (supported) WIDCOMM driver? (Broadcom acquired Widcomm in April 2004.) If so, there might be support also for this BTW 4.0 available at some point?

Subject: Making an IBM Broadcom bluetooth interface work with XP2

This no responsibility is accepted for any problem or damage that occur including and warranty or product support violations.

It has not upset my windows XP home or XP Pro, no flame mail please.

In past I have "hacked" the Microsoft Bluetooth driver into thinking the USB device is supported by XP.
1 Remove all WIDCOMM drivers any version via add/remove programs function of control panel
2 Check in the Device Manager to find if any drivers exist for the device and remove them.
3 using the FN-F4 should now be able to switch off the bluetooth device

Widcomm recognises the following devices taken from the widcomm BTWUSB.INF for widcomm 4.0

VID 0A5C is the Broadcom signature
PID 201E is the USB device code found in the Device Manager -> Device ?USB -Properties -> Details tab .
The Device Instance ID = USB\VID_0A5C&PID_201E

%BROADIBM.DeviceDesc%=SUSPENDUSB, USB\VID_0A5C&PID_201E ; Broadcom-IBM VID&PID Smart dongle <<<Think PAD

Now to make Win XP sp2 driver think that this bluetooth device is a valid device.
The file is in C:\WINDOWS\inf on a XP Home edition and C:\WINXP\inf on XP Professional edition

Edit the file bth.inf with NotePad/WordPad, which contains the lines :-

[Broadcom.NT.5.1]
Blutonium BCM2035 Bluetooth 2.4 GHz Single Chip Transceiver= BthUsb, USB\VID_0A5C&PID_200A
BCM2033 Bluetooth 2.4 GHz Single Chip Transceiver= BthUsb, USB\VID_0A5C&PID_200F

You can see that this is not the correct code for the PID for the Broadcom Bluetooth for the Think pad

The entry needs to be changed to as below

[Broadcom.NT.5.1]
Blutonium BCM2035 Bluetooth 2.4 GHz Single Chip Transceiver= BthUsb, USB\VID_0A5C&PID_201E
BCM2033 Bluetooth 2.4 GHz Single Chip Transceiver= BthUsb, USB\VID_0A5C&PID_201E

Save the changes

The 200A and 200F are changed to 201E to allow detection by the driver.

This has now defined the Broadcom generic driver to load when the device is detected.

Reboot laptop
Using the FN-F4 should now be able to switch on the bluetooth device

Device detection should take place.
The detected device will ask to install automatically.
Select the "DONT detect driver I will select device",
Click next and Select the generic broadcomm driver.

When the question occurs about Generic Bluetooth driver, Click install and find automatically
When the question occurs about Microsoft Bluetooth Enumerator driver, Click install and find automatically.

The drivers for standard modem links etc are loaded.

The Bluetooth icon should appear into Control Panel and in system tray.

Hopefully you can see and 'pair' with your mobile phone by using the Bluetooth control panel.

If this detection does not work try checking for removal of all drivers related to widcomm in c:\windows\system32. This can be found by using manual install of widcomm drivers and noting the names of driver files.
Go back into Device Manager and right click for properties and click uninstall driver so that windows re detect the device. Ideally this some came back with a yellow question mark if you cancel installation of drivers.

This method is not supported by MS

but does MS ever want us to meedle beneath the hood.

. It has not damaged my system but I cannot make any promises about your system.
NO REPSONIBILITY IS ACCEPTED FOR ANY PROBLEMS OR DAMAGED WHAT EVER CAUSED BY USING THIS PROCEDURE

Finally I have used this method to get many BT devices not currently supported because they are so new but emulate the old functions, for example the new Belkin BT USB adapter

I used PC Suite 6.6 not 6.7 to connect to my phone 6230i, either way you will have to remove and reinstall the suite for correct
bluetooth detection to take place.
Maybe you should try using PS Suite version 6.8 before trying above procedure

Hi,

Looking at the bluetooth driver in my T43, it uses Broadcom (aka WIDCOMM) v. 5.1.2535.0 - the system is identified as "IBM Integrated Bluetooth IV". There also appears to be something called "Microsoft Bluetooth Enumerator" installed, location: "on IBM Integrated Bluetooth IV". So this could in theory be in conflict with the Broadcom one? Curious all the other connections seem to work fine, it is only when one attempts to connect to Internet via a Nokia PC Suite when the connection suddenly fails. I can transfer images from the cameraphone with bluetooth with no problems.

Any suggestions for what to try or where to look for help?

Best,

Using this method, I tried to change my Blue Soleil dongle to be driven by microsofts drivers so that i could use the Bluetooth API from microsoft. But I gets the error message telling that

"windows has stopped this device as it reported problems (code 43)"

Wow... the method of hacking the bth.inf file worked like a dream for my D-Link DBT-122 dongle... after hacking it was detected as microsoft Bluetooth. Now I am enjoying the benefits of being supported by microsoft drivers....

Nice to know you can get Win XP to recognize DBT-122. I would appreciate if you gave us the hack. What needs to be added/changed in bth.inf.

Thanks in advance.

Hi,
There is program called USBVIEW.exe which gives the PID and VID you need to set up the bth.inf settings as previously described in earlier postings

http://www.usbman.com/WebDrivers/USBview/USBVIEW.EXE

Good Luck
Jim

How can I know about the PID that I need to put in the inf file ?

tfm

ok I got it, the driver is working. Great work

the following link helped:

i dont have on my xp the bth.inf file. i've searched

c:\\windows\\inf

and the whole computer... maybe there is another file/name?
...

thanks

Hi if you are using Windows XP Professional see the value by
C:\> "echo %SYSTEMROOT%"
failing that in command console
c:\> dir/s bth.inf

Will search the hard drive to find the file I presume you have enable/ unhidden the system files in explorer .
