Windows 10: "BLUETOOTH NOT AVAILABLE ON THIS DEVICE"

when i tried to connect my bluetooth speaker to my laptop, i wasn't able to find the bluetooth toggle switch in the bluetooth settings.

I tried to run a troubleshooter for bluetooth, and then it shows "device does not have bluetooth."

the bluetooth was working fine just a week before.

Also, i wasn't able to find bluetooth in the device manager, but i noticed that there is an unknown device in the other device group.


I tried my best to solve the problem,

can anybody please help me ?

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 is not available on this device" after update

I have recently run an automatic Windows update (update for Windows 10 version 1803 for x64-based Systems (KB4023057)) after which my Bluetooth has stopped functioning. I have tried the solutions suggested in previous discussions to no avail:

-- No Bluetooth listed on Network and Internet settings menu

-- Troubleshooter says "Device does not have Bluetooth"

-- Bluetooth and other devices menu visible, but no button to turn on Bluetooth; a message saying "Bluetooth is turned off" under every saved device

-- Driver update clients won't find Bluetooth-related drivers to update

-- Bluetooth Support Service enabled and running

-- Drivers listed in the Bluetooth folder in Device Manager: Device Identification Service; Microsoft Bluetooth Enumerator; Microsoft Bluetooth LE Enumerator; Qualcomm Atheros AR3012 Bluetooth 4.0. All appear as up-to-date when searching for updates. No
Generic Bluetooth Adapter in sight.
