Windows 10: why does bluetooth auto connect a device when I turn on bluetooth ?

I have two devices set up. When I turn BT on it automatically connects to one of them. If I then disconnect that one BT automatically connects that one again. I can never connect the other device. Someone please tell me how to fix this problem. Thanks.

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 USB Dongle

Ok so here's a question. I had a revelation today that: "Duh, my keyboard/mouse is bluetooth, shouldn't that be the same thing?" My goal here is to get my new Motorola HT820 bluetooth headphones to work with on my computer.

Keyboard/Mouse is Logitech MX5500 Revolution, bluetooth wireless, came with a USB dongle that they connect through. I tried today to get the headset to work, and it won't receive sound. I can get it "connected," but with complications. I'm using Windows XP, have Setpoint 4.7, and I've tried the following:

-Changed the radio settings to a bluetooth hub instead of locked to the keyboard/mouse.

-Clicked "Connect Other Devices."

- Paired headphones with windows. Windows connects correctly, the device reads connections, windows shows it as "already connected" when I try to connect it again. I click on Control Panel -> Bluetooth Devices, and I see the "Motorola HT820" listed as "Passkey enabled," but it doesn't say "Connected" like the keyboard and mouse do. Also, audio does play on the headphones.

-Click on Properties on HT820, and then on services, it does not show any services at all.

- Searched around google, logitech, motorola websites & forums to answers or help, nothing. Closet I got was logitech's "Bluetooth FAQ" which has the following paragraph (http://www.logitech.com/lang/pdf/bluetooth/bluetooth-faq.pdf):

"3.6 How do I listen to music wirelessly with a Bluetooth headphone?
All you need is a Bluetooth headphone and a media player such as iTunes or Windows Media Player 10. For optimal results, it is recommended you use a headphone with Bluetooth 2.0 Enhanced Data Rate, to benefit from the maximum bandwidth (up to 3Mb/s).
Please refer to our online "How To" documents for step-by-step instructions related to your specific device (www.logitech.com/bluetooth/howto)." [That link transfers you back to the same pdf document - it's a circle]

-I tried to install latest Widcomm stack from broadcomm's website, but it says it's not compatible with this dongle.

-Called Logitech Tech Support - got a total jerk girl who straight up said "No i can't help you." And then wouldn't give me the time of day after that.

I've read on threads on Logitech forum that people are using this headset with logitech dongles. Any help getting this connected? I just don't want to have 2 bluetooth dongles connected when I rly only should need this one. Otherwise I guess I'll just purchase one of the ones above, and use that to connect my keyboard, mouse, and headphones all in one swoop.

Sidenote: anyone have experience/knowledge with behavior when 2 bluetooth USB dongles are connected to the same computer?

 

Cannot connect to Bluetooth audio devices (only) under 21H1.

I had no problem connecting Bluetooth audio devices while running Windows version 20H2, and had 3 different audio devices paired and working normally. Upon upgrading to the latest Windows 10 version (21H1, 19043.1348), they can no longer connect. There's nothing wrong with the devices. My 2nd system is running 20H2 and is connecting fine with them. On my primary system running 21H1, I go to the Bluetooth settings screen, see my paired devices in the list. I turn on a Bluetooth audio device... and nothing happens. Previously the laptop would auto-detect the audio device and I'd be good to go. So I select the paired audio device in the list, see the option button to "CONNECT" and press it. IMMEDIATELY, I'm given this message: "That didn't work. Make sure your bluetooth device is discoverable." It's obvious it's not even trying. It's an instant response. On my 20H2 laptop, when I try to manually connect to a Bluetooth audio device that's not turned on, it takes about 20 seconds or so until the "didn't work" message to appear. It's clearly trying. NOTE: I have a mouse device connected via Bluetooth and it's working perfectly fine. It's only audio devices that fail. Another vexing related issue -- if I try to remove any of my Bluetooth audio devices from the paired list, I get a "Remove Failed" message and nothing happens. Troubleshooting: Went to Devices --> Bluetooth. Did a View of hidden devices... and yes, there were duplicates of these devices listed. I deleted all of them. I rebooted and while they are absent from the Devices list, they're still showing up in the Bluetooth interface and behaving as before. I ran the Bluetooth troubleshooter that claimed to find a problem and fixed it, but rebooting showed that not to be the case. Either something appears to be wrong with 21H1, or I have some screwy configuration conflict going on.. I've got Realtek Bluetooth hardware. I have uninstalled Bluetooth and reinstalled the Realtek drivers. No help. Upgrading to 21H1 was long and tedious--I don't want to roll back to 20H2. Is there anything I can try to fix this? Thanks!
