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!

 

Bluetooth Device not connecting.

• I performed a reset through cloud download of my HP Pavilion 15-dk0050tx Windows 10 Laptop from windows' settings app.
  
• After the reset, I observed that my laptop is unable to connect to my mobile through Bluetooth.
  
• So I tried a few things from "answers.microsoft.com".
  
• What I tried are:
  

1. Updated my windows to the latest version.
   
2. Updated all windows apps from Microsoft Store.
   
3. Updated my all drivers from HP Support Assistant.
   
4. Performed troubleshoot of Bluetooth from Windows' settings.
   
5. Tried to update drivers from the device manager.
   
6. Removed my device from Bluetooth devices & tried to connect.
   
7. Uninstalled my device from the device manager & restarted my laptop.
   
8. Tried to connect my device again but failed.
   
9. To ensure which device(laptop or mobile) has a Bluetooth connectivity issue, I used another mobile but it was also unable to connect.
   

please suggest to me what should I do now

 

bluetooth connectivity problem after upgrading window8.1 to windows10

Sir,

I did the changes as described by you.

BUT:

• It did not work
• I am able to send files to my android phone Samsung Galaxy J2 from my Laptop Sony VAIO SVE14137CN.
• Files CAN NOT be sent from the android phone to the Laptop- Message says connection failed even when it is paired with VAIO.
• Tried many times by removing device and then pairing.

Pl. suggest further steps (Bluetooth drivers are updated: Details are as follows-

• Microsoft Blue Tooth Enumerator-Location: on Qualcomm Atheros AR3012 Bluetooth (R) Adaptor.
• Microsoft Blue Tooth LE Enumerator-Location: on Qualcomm Atheros AR3012 Bluetooth (R) Adaptor.
• Qualcomm Atheros AR3012 Bluetooth (R) Adaptor-Location: Port_#0002.Hub_#0004.

Thanks and regards.
