When you tell Windows to pair and connect to a Bluetooth peripheral, Windows establishes a connection and asks the device what profiles it uses and what kind of security it supports.
It displays the device information in the settings window that appears when you want to add a Bluetooth device. Windows sees the peripheral and establishes low-level communication where it finds out the devices name and what kind of device it is. Typically, Windows acts as a host and the peripheral is put into pairing mode, where it advertises its presence to any nearby Bluetooth devices. Windows establishes a connection with a Bluetooth peripheral through a pairing process. Often a driver error for the peripheral will be reported in this case. Missing, corrupted, or incorrect profile versions will cause pairing and connection problems.

For example, while Windows 8 through 10 support Bluetooth audio, in Windows 7, Windows audio profiles and drivers have to be installed with third-party software, such as the driver packages on the Plugable website or the CD that comes with the adapter. The stack has separate modules, called profiles, that standardize how Windows communicates with particular Bluetooth device types, such as A2DP (stereo audio), HID (human interface devices like keyboards and mice), HSP/HFP (headsets and hands-free devices), and many more.ĭifferent Windows versions come with different profiles. It also receive data from peripheral devices connected through the Bluetooth adapter and shapes into data that can be understood by other programs in Windows.

This is software arranged in layers that processes and prepares Bluetooth data for particular purposes. Windows creates the data packets to send to the Bluetooth adapter in its Bluetooth stack. Having drivers present for more than one Bluetooth device also causes problems because Windows does not know which one to communicate to. Using a wrong or corrupted driver means that Windows is not able to communicate with a device properly.

A driver tells Windows how to communicate with a hardware device and how to interpret the information it sends and receives. It then searches for a driver for your device. When you plug your adapter into a USB port, the computer queries it for information about what kind of device it is. Out of date, missing, or corrupted USB controller software will cause the adapter to malfunction regardless of the port it is plugged into. The easiest way to identify this is to try another port. A physical problem with the USB port will cause malfunctions. The Bluetooth adapter gets its data packets from your computer’s USB controller through the USB port. Having a large number of strong Wi-Fi signals in the area can also cause radio problems, since Wi-Fi and Bluetooth use the same radio frequencies, but Wi-Fi is much more powerful.
Radio problems can also be caused by objects between the adapter and the receiver blocking and absorbing the signal.
In our experience, most radio problems are caused by radio noise coming from components in the host computer, especially poorly-shielded USB 3.0 ports and unshielded components in desktop computers. Radio signal problems tend to show us as reduced range, frequent disconnections, and lag. Adapter hardware problems will usually show up when the adapter fails to work at all. This process can suffer in two ways: radio problems that block or corrupt the radio signal and problems with the hardware of the adapter itself. It receives radio packets from the peripheral device, decodes them into data packets, and sends them to the computer. It takes packets of data from your computer, encodes them into a radio signal, and sends them to your peripheral device. As mentioned above, the Bluetooth adapter itself is pretty simple.
