Connecting a Bluetooth peripheral to the Microsoft Bluetooth Transceiver/Dongle (W2000-XP)
Posted: 10-11-2003, 11:29 PM
Transceiver/Dongle (W2000-XP)
Especialy a Sony Ericsson T610
Original configuration :
Desktop PC under Windows XP Pro SP1 with the Bluetooth patch, BT
Intellipoint and BT Intellitype.
Two months ago, I bought the nice MS Bluetooth Desktop for my home PC. It
quite a good set as the keyboard and the mouse are very comfortable to use
and efficient concerning operating range. The only thing that used to make
me sad was the monstrous power consumption of the mouse (3weeks with the
included Energizer).
That's what I thought before I got another Bluetooth peripheral..
When I thought about changing my cell phone, I turned myself to the new
Sony-Ericsson T610 for its Bluetooth support.
The anger against Microsoft came when I tried to establish the connection
between my phone and my PC. I successfully installed the Ericsson software
pack but the highly wanted "My Bluetooth places" icon was still not
appearing; and all that I was able to establish was a remote access
connection using my phone as a modem.
Searching on Internet, I found that this fail was due to a lack in the
Microsoft's Bluetooth stack that is supplied with the BT Desktop.
Actually, it is not able to manage other profiles than the "HID profile"
(Human Interface Device) used for mice, keyboards. this leading to the fact
that "as it" the Microsoft Bluetooth package can't be used to connect other
peripherals than the supplied mouse and keyboard.
I also found that the MS dongle is using the CSR chipset that is used in
most of dongles such as TDK, D-link. which are also using the same stack
base from Widcomm.
My new aim became to use the Widcomm BT Stack (v1.4x as 1.3x doesn't support
the HID profile) with my Microsoft dongle.
Still surfing I was dropped on this page :

on which can be read :
QuickHowto Widcomm 1.4.1.4
Here is an quick translation how to install widcomm 1.4.1.4
First download Acer 1.3.2.7 and Dell 1.4.1.4 Software.
ftp://ftp.support.acer-euro.com/net.../bt500_1327.exe
http://support.ap.dell.com/ap/en/fi...1611&location=2
Extract all Files.
Copy license.dat from Acer into extracted Dell-Directory.
Begin install
After Install, software ask for license.dat or licensekey, cancel this step.
Donīt click bluetooth-icon!!
Now we need an Hexeditor.
Open btsec.dll (into c:\windows\system32) with hexeditor.
Patch this bytes:
Offset 0x43EE old Value: 75 4E new Value: 9090
Offset 0x4402 old Value: 75 3A new Value: 9090
Offset 0x4408 old Value: 74 39 new Value: 9090
Save btsec.dll and try it out.
If you canīt edit btsec.dll kill btstac~1.exe before in task manager
This perfectly worked under the Windows 2000 Pro SP3 laptop that I use at
work, but I didn't tried to connect my BT Desktop as it requires
Intellipoint/type for Bluetooth which only works under XP. But the phone BT
connection is OK.
After testing the Widcomm stack under W2000, I came home to make it work on
my WinXP desktop computer which was announced to be much more rejoicing as
the MS dongle drivers are included in the XP BT Patch.
Here is the way I make it work :
Required :
MS Bluetooth Patch for XP installed
MS Intellipoint and Intellitype for Bluetooth installed
The dongle unplugged.
Contrary to windows 2000, as XP is updated for Bluetooth it has the drivers
for the MS Bluetooth Transceiver. So they've got to be deleted from the
source because we need to use the one included in the Widcomm stack.
To do that just look for the files containing "Bluetooth" in C:\Windows\Inf\
and delete them.
Then the process for the Widcomm installation is the same as for Windows
2000
But the problem is that, to work fine, the mouse and the keyboard need
Intellipoint and Intellitype which cannot be installed if the MS XP Patch
for Bluetooth is not present.
So you need to install it first to put Intellipoint and Intellitype and then
delete it (and the inf files) to install the Widcomm drivers.
That's the way It work, and fine.
The next step is to make it work so fine with Linux.
