The Bluetooth stack that comes built into Windows 7 is nothing more than adequate. However you can replace the Bluetooth stack and take advantage of extended functionality provided by other manufacturers.
What is the Bluetooth Stack?
Windows 7 Bluetooth stack is foreseen, connected to Bluetooth devices via USB support. Such devices could headsets, mobile devices, or even controllers, but the Windows stack is what it can or unrestricted support. Simply put, Microsoft has not offered Bluetooth with enough depth and stack use range of modern Bluetooth device cover.
In Windows 7 the Bluetooth driver options are limited, resulting in users for alternative software decide use their Bluetooth devices as was intended. As a result of other manufacturers offer their Bluetooth options that can be installed or by purchasing the stack software from the manufacturer’s website either through Windows Update or device installation CD.
Installing the Windows 7 Bluetooth Stack
Windows 7 provides support for Bluetooth 2.1+EDR and features new technologies such as Secure Simple Pairing which puts the operating system in charge of selecting the most appropriate pairing method.
In addition, the Windows 7 Bluetooth stack supports PAN, DUN, SPP, HID and HCRP, just as Windows XP and Vista do. To install the Windows 7 Bluetooth stack you need to first connect a Bluetooth device via USB; this will begin the Windows Add new hardware wizard and once complete your device will have control over the Bluetooth connection protocols included in the Windows 7 stack. See Configuring the Windows 7 Bluetooth Manager for full instructions on installing Bluetooth on Windows 7.
However as we’ve seen, this can often prove inadequate for many users. As such there are alternative Bluetooth stacks available.
Changing Bluetooth Stacks
There are several alternative Bluetooth stack, consider, and they appear the hardware that you install. For example the Windows 7 Bluetooth stack supports only CSR chipset devices such as headsets, stereo receiver, remote control, etc. Devices with a different chipset, another is stack. You need to be aware at this stage, that Windows 7 can only a single Bluetooth stack.
This means that the advantages of one another, not-CSR chipset need to Bluetooth device, you uninstall the default stack and do a fresh install. Of course need to do a certain amount of planning here, because each device that works with the default settings may stack with a new stack to work.
Alternative Bluetooth Stacks
There are several locations where you can find and download alternative Bluetooth stacks. These are usually the support pages of certain hardware devices – for instance, the Lenovo Thinkpad Bluetooth software uses the Widcomm stack, the oldest version of which pre-dates the Windows 7 Bluetooth stack.
Other Bluetooth stacks include the Toshiba stack, BlueSoleil, EtherMind and CSR are also developing their own stack. Your Bluetooth device may require any one of these; for further information, check your hardware manufacturer support pages.
