Windows 10: Bluetooth no longer able to find devices

The Bluetooth on my desktop can no longer find Bluetooth devices. Namely, my wireless headphones but have tried with other devices as well and it cannot locate anything. I have uninstalled the drivers, run the troubleshooter and still nothing. it's been like this for almost two years now, maybe longer. I've always been on Windows 10 on this desktop. I also cannot find this Bluetooth device, as in when I search on my phone for all nearby devices, my desktop's Bluetooth doesn't pop up.

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 device is shown as not present.

Hello Dominika,

Thank you for getting back to us. Since the issue still persists after following the steps on the article above, we'd like to know more. Kindly answer the following questions:

• Did you checked whether the Bluetooth device is listed under hidden devices in Device manager?
• What is the make and model of your Bluetooth device?
• Can you tell us the specific bluetooth devices that you're using on your Windows 10?
• Have you checked whether the Bluetooth driver is listed under installed programs under Programs and features?
  

Meanwhile, we suggest that you check if the Bluetooth services is enabled by following the steps below:

• Press Windows + R keys on the keyboard, type services.msc and press OK.
  
• Right click on Bluetooth Support service and select
  Restart.
  
• Right click on Bluetooth support service and select Properties
  and check if the startup type is Automatic.

We'll be waiting for your response.

 

Bluetooth No Longer In Device Manager

Last night, I had a bluetooth keyboard connecting perfectly to my Lenovo AIO 700 (as it had done since I brought it a few weeks ago). This morning, there was no bluetooth connection.



Checked settings - bluetooth not listed as an option. Checked Services.msc and changed bluetooth options to "automatic". Ran driver updates through device manager and was getting "code 45" on all of them (icons were greyed-out but showing under the bluetooth
node). I uninstalled all drivers and restarted and, since that point, there are no bluetooth drivers ANYWHERE in device manager (including in hidden files). I have done:

• A system restore
• A full system reset
• Cmd prompts:
• dism /online /cleanup_image /restorehealth
• sfc /scannow
• Hardware troubleshooter x2
• Upgraded BIOS from Lenovo website (although nothing in my BIOS - old or new -that relates to bluetooth anyway that I can see)
  

Basically, I have done everything I can find online and I am getting nowhere... Tried to speak to Windows support but requested call from them twice and they never called. Looks like the hardware is no longer installed for some reason but I can't get it
to pick it back up again. Only other thing of note is that in device manager/universal serial bus controllers I have a yellow exclamation mark next to "unknown USB device (Device Descriptor Request Failed)" which I have tried to uninstall several times but
keeps reappearing with the same description.

Any suggestions appreciated! Thanks!
