Bluetooth driver error

About Bluetooth Device Drivers: A Bluetooth Driver is a software program that allows your operating system to communicate with a Bluetooth device and vice-versa.Bluetooth Device Drivers are operating system and device specific. In other words, for the same Bluetooth Device, you are likely to require a different Driver for Windows 10, Windows 8 or Windows 7 to the Driver you would need for Windows XP. Also, one Driver will work only with one type of Bluetooth Device.Start DownloadIn most cases, Bluetooth Device Driver errors occur when the required Driver is either missing or corrupt. In this article, we will discuss the following topics:What are the common causes of Bluetooth Device Drivers problems?How to troubleshoot Bluetooth Device Drivers errorsCommon Bluetooth Device Drivers Problems:If you encounter a problem with your Bluetooth Driver, your Windows operating system will fail to identify the connected Bluetooth Device. Most of the time, you will be made aware of a problem in a Bluetooth device driver by the appearance of an error message on your screen.Below are some of the common Bluetooth Driver errors and their meaning:Error 1 – “Bluetooth device not found. Please verify that your Bluetooth device is properly connected and turned on”Meaning – The above error has been reported mostly in Windows XP, and it occurs because Windows XP installs its own Bluetooth device driver instead of the driver that was included with your Bluetooth device.This is essentially a Bluetooth pairing issue, you may also see the error “Bluetooth cannot start, Hardware not found” This can be a Bluetooth Drivers issue but it is also worthwhile trying the following which can fix this Bluetooth hardware not found issue.Go to Device Manager Click on Bluetooth, select the properties of the first entry which is usually a wireless bluetooth moduleIn properties dialogue box select the Power Management tab > uncheck the box turn off device to save powerThis may solve the problem, if not you may need to use the link at the end of the article to update your Bluetooth DriversError 2 – “This device is not configured correctly. (Code 1)”Meaning – The above error means that either the required Bluetooth Driver is not installed on your computer or it is missing.Error 3 – “This device cannot start. (Code 10)”Meaning – The above error may mean that your Bluetooth Driver is outdated.What can I do to fix Bluetooth Software Drivers problems?Fix the Bluetooth error via Device ManagerWindows computers contain a built-in utility, Device Manager, which allows you to identify and troubleshoot driver-related errors. You can access Device Manger via the Control Panel window.Outlined below are steps to show you how to update drivers via Device Manager in Windows 7 and Vista, and fix driver errors occurring due to an outdated device driver.Open Control PanelDouble-click Device ManagerLocate and double-click the Bluetooth driver that you need to updateClick the Driver tabClick the Update Driver buttonClick Search automatically for updated driver softwareWindows will now search for the latest driver on your system and the Internet.
