Windows 10: Bluetooth Stopped Functioning

When the Bluetooth is on and connected to a device, and the device is selected as the output, Windows no longer plays sound through the Bluetooth device. It plays through the computer speakers. Changing the output does not work, nor does turning the Bluetooth off and on, updating drivers, changing the equipment, etc. It worked yesterday, no settings were changed, today it does not work. A list of Bluetooth devices shows up, it makes a sound indicating that they are connected to the computer, the device is selected as audio output, then the computer plays sound through the computer speakers.

No bluetooth after system restore

Thank you for your reply.

I mean I have used a Windows system restore point. I tried restoring bluetooth with commands in CMD (sfc/scannow; DISM /Online.....) and by updating and uninstalling devices in the device manager. Update did not work. Uninstalling bluetooth devices made Bluetooth disappear out of the hidden devices list.
All my steps I took worked but did not change anything in my bluetooth device list.

I am using the bluetooth of my mainboard. MSI Z370M Gaming Pro AC
My guess would be, that disabling the bluetooth network adapter before using a system restore point, disabled Bluetooth after using the system restore point.

In the device manager I get this message in the USB Device list for a unknown USB Device:
Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.

 

Bluetooth Technology Gets Faster With Bluetooth 3.0

From its annual All Hands Meeting in Tokyo this week, the Bluetooth SIG formally adopted Bluetooth Core Specification Version 3.0 + High Speed (HS), or Bluetooth 3.0. This latest iteration of the popular short-range wireless technology fulfills the consumers' need for speed while providing the same wireless Bluetooth experience – faster. Manufacturers of consumer electronics and home entertainment devices can now build their products to send large amounts of video, music and photos between devices wirelessly at speeds consumers expect.
Bluetooth 3.0 gets its speed from the 802.11 radio protocol. The inclusion of the 802.11 Protocol Adaptation Layer (PAL) provides increased throughput of data transfers at the approximate rate of 24 Mbps. In addition, mobile devices including Bluetooth 3.0 + HS will realize increased power savings due to enhanced power control built in.


"Like Ricky Bobby in Talladega Nights, this latest version was 'born to go fast,' said Mike's Blog, Ph.D., executive director of the Bluetooth SIG. "Utilizing the 802.11 radio was a natural choice as it provides efficiencies for both our members and consumers – members get more function out of the two radios they are already including in devices, and consumers with Bluetooth 3.0 + HS products will get faster exchange of information without changing how they connect. We are excited to expand the possibilities of the PAN."

This newest version of Bluetooth technology builds on the inherent qualities of the current 2.1 + EDR version, including Simple Secure Pairing and built-in, automatic security. And as with all versions of theBluetooth specification, v3.0 + HS provides developers, manufacturers and consumers with the benefit of backwards compatibility, enabling both the expansion and enhancement of this technology with every new specification release. Once products reach the market, the easiest way for consumers to learn which devices are compatible with other Bluetooth enabled devices is to visit the Bluetooth Gadget Guide.

Applications
With the availability of Bluetooth version 3.0 + HS, consumers can expect to move large data files of videos, music and photos between their own devices and the trusted devices of others, without the need for cables and wires. Some applications consumers will experience include:

• Wirelessly bulk synchronize music libraries between PC and music player or phone
• Bulk download photos to a printer or PC
• Send video files from camera or phone to computer or television

Availability

The Bluetooth SIG's formal adoption of the specification is only the first step in the product lifecycle. News out today from wireless chip manufacturers and Bluetooth SIG member companies Atheros, Broadcom and CSR shows the second step – getting silicon solutions to device manufacturers – is already underway. End products for consumers are expected to be in the market in 9 to 12 months.

Technical Specifications
This new specification release includes several major enhancements (learn more here - page requires member login):

• Generic Alternate MAC/PHY (AMP)
• 802.11 Protocol Adaptation Layer (PAL)
• Generic Test Methodology
• Enhanced Power Control
• Unicast Connectionless Data

Bluetooth Function GONE

Hi,

I'm Diego Rios, an Independent Advisor willing to help other Microsoft customers.

Regarding your question:

Try these procedures:

Before proceeding, we need more information to help you better.

Did you checked whether the Bluetooth device is listed under hidden devices in Device manager?

Have you checked whether the Bluetooth driver is listed under installed programs under Programs and features? (As you have reinstalled the Bluetooth.)

Note:

In device manager, click on "view" tab and select "show hidden devices" and check whether Bluetooth device/driver is listed.

To check the drivers installed in Programs and features, Press Windows + X keys on the keyboard and select Programs and features and check whether the Bluetooth driver is installed.

Until you get back to us with the required information, follow the below steps and check if it helps.

Step 1:

I would suggest you check if Bluetooth Support service is started.

Press Windows + R keys on the keyboard, type services.msc and press OK.

Now, find Bluetooth Support Service and start it

Double click on the Bluetooth Support Service set the startup type as Automatic.

Reference: I would suggest you to check whether the drivers are up to date. Refer to the below link on how to download and install the drivers in Windows 10.
