Microsoft bluetooth stack install

How to Restore a Microsoft Bluetooth Stack

Many Bluetooth devices install third-party device drivers which disable the Microsoft generic Bluetooth software or «stack» in older versions of Windows, and prevent it from loading. Other devices, notably Blackberry cell phones, will only connect to a PC that is running Microsoft’s Bluetooth drivers. Running more than one set of Bluetooth drivers can cause stability problems and is not advisable. In order to allow the Microsoft drivers to load, you must uninstall any third-party Bluetooth drivers.

Step 1

Uninstall the third-party drivers through Control Panel. Click on «Start» and «Control Panel,» then click on «Add/Remove Programs» in Windows XP or «Uninstall a program» in Vista. Locate the third-party drivers and uninstall them.

Step 2

Click on «Start» and «Run,» then type «%windir%\inf» in the «Open» box and click «OK.» Look for the file «bth.inf.old» or «bth.bak.» If neither file is present, go to Step 3. Right-click on the file and select «Rename.» Rename it to «bth.inf.»

Step 3

Restart the computer and connect your Bluetooth adapter. Windows will detect the new hardware and the Microsoft Bluetooth stack will load automatically and install the correct drivers. If the original Microsoft stack is damaged and fails to recognize your Bluetooth device, you can reinstall Windows Bluetooth drivers from third-party sites or install the latest updates for your version of Windows from Microsoft. Microsoft doesn’t provide a separate download of the Bluetooth drivers.

Step 4

Download the free Bluetooth Driver Installer from BluetoothInstaller.com. Restart your computer and when Windows prompts for the Bluetooth driver, click «Cancel.» Double-click on «BluetoothDriverInstaller.exe.» Click «OK,» check the box to accept the terms and conditions and click «Next.» When the software has found the Bluetooth adapter, click «Next» to install the driver. Click «Next» to test the Bluetooth adapter and then click «Exit» to complete the installation.

Step 5

Download Driver Whiz from the company’s website (see References). Driver Whiz is a freeware program that will scan your system for any corrupt or missing Windows Bluetooth Drivers and update them automatically to the latest compatible version. Click on the EXE program file to start the download and select «Run» in Internet Explorer or «Save As» in Firefox. Click «Run» and follow the installation instructions on-screen. Driver Whiz will create a System Restore Point before installing new drivers.

Step 6

Download the latest updates for your version of Windows from Microsoft. For Windows XP, go to the Windows Update Center on the Microsoft website. In later versions of Windows, click «Start,» click «All Programs» and then click «Windows Update.» If Windows detects any important updates, install them by clicking on the link «Install Updates.» Restart your computer when prompted.

Installing a Bluetooth device

There are two installation types for Bluetooth profile drivers:

• Client-side installation for remote devices where the remote device advertises its services and the computer connects to it. Examples include: mice, keyboards, and printers.
• Server-side installation where the computer advertises services and remote devices can connect to the computer to use those services. For example, a vendor could author a server-side installation to enable a mobile device to print to a printer attached to the computer.

These two installation types require different installation procedures.

Installing a client-side profile driver

A user that wants to use a Bluetooth-enabled device will bring the device within range of the computer and initiate a connection from the computer to the remote device using the following installation sequence for a client-side profile driver.

1. Select Add a Bluetooth device in Control Panel to find all devices within range of the computer.
2. Select the device to pair with.
3. Pair the device with the local radio. This may or may not involve a PIN exchange.
4. The local radio issues an SDP inquiry to identify the services supported on the remote device.
5. The Found New Hardware Wizard searches for appropriate drivers on the local hard disk drive, and on Windows Update.
6. If the Found New Hardware Wizard does not find an appropriate driver for the device, it prompts the user to insert the profile driver installation media that contains the profile driver’s device setup information file (INF file).

Installing a server-side profile driver

The Bluetooth driver stack supports service GUIDs as defined by the Bluetooth SIG, as well as custom GUIDs (that is, GUIDs that are not defined by the Bluetooth SIG).

The guidgen.exe tool provided with the Microsoft Windows SDK can be used to create custom GUIDs.

A user-mode installation application must be written to expose computer functionality that remote Bluetooth devices can use.

The installation application must communicate with the Bluetooth driver stack to create a service GUID for the functionality to expose. Vendors specify the service GUID in the application and in their device installation INF file.

The installation application must call the user-mode API BluetoothSetLocalServiceInfo. Before the application can call this API the application must have the SE_LOAD_DRIVER_NAME security privilege. The following code example demonstrates how to obtain this privilege. Note that the example does not demonstrate error handling.

HANDLE procToken; LUID luid; TOKEN_PRIVILEGES tp; OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &procToken); LookupPrivilegeValue(NULL, SE_LOAD_DRIVER_NAME, &luid); Tp.PrivilegeCount = 1; Tp.privileges[0].Luid = luid; Tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; AdjustTokenPrivileges(procToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES), (PTOKEN_PRIVILEGES) NULL, (PDWORD)NULL) 

Profile driver INF file

A profile driver’s INF file contains information about a Bluetooth device for client-side installation. For a server-side installation, the INF file specifies a device ID that corresponds to the service GUID created by the installation application. All Bluetooth devices are members of the Bluetooth class. The Bluetooth class installer (Bthci.dll) assists in installing profile drivers.

For more information about creating and distributing INF files and installing drivers, see Creating an INF File and INF File Sections and Directives.

Plug and Play IDs

The Bluetooth driver stack generates hardware IDs according to the following templates:

• BTHENUM\< ServiceGUID>_VID& nnnnnnnn
• BTHENUM\< ServiceGUID>_VID& nnnnnnnn_PID& nnnn
• BTHENUM\< ServiceGUID>_LOCALMFG& nnnn

The Bluetooth driver stack generates compatible IDs according to the following template:

ServiceGUID is a 16-bit GUID expanded into a 128-bit GUID, as defined by the Bluetooth specification. For example, corresponds to an HID device.

• The 8 digits following VID& correspond to the vendor ID code.
• The 4 digits following PID& correspond to the product ID code.
• The 4 digits following LOCALMFG& correspond to the manufacturer of the local Bluetooth radio.
• The VID/PID and LOCALMFG tags are independent of each other.

The most generic device ID is a ServiceGUID by itself. For example:

The Bluetooth driver stack can be restricted to load your profile driver and software to run only on a specific release of a remote device by using Plug and Play IDs in both the remote device and the INF file. Note that the Bluetooth driver stack generates a VID/PID pair only if the device publishes a Plug and Play ID that the stack can detect using SDP. For example:

The Bluetooth driver stack can be restricted to load profile driver and software to run only on a specific local Bluetooth radio by specifying the LOCALMFG tag in the device ID in your INF file. For example:
