Windows 10: Bluetooth Immediately Says 'Couldn't Connect' When Trying to Connect to Any Device

I have a lenovo 7 16ARP8 laptop, and my bluetooth abruptly stopped working about two days ago. I've tried updating my driver and laptop, running the bluetooth troubleshooter, turning bluetooth off and then on, and resetting my device. None of this has worked so far. Is there anything else I can do to make my bluetooth function work again?

Bluetooth Audio Device will not be removed and will not connect

I have a set of bluetooth speakers connected to the Nobsound 10-G Bluetooth device and for the past 6 months or so its worked fine. Two nights ago I put my laptop to sleep and occasionally the device has a strange issue where everything wakes up except the screen so i have to turn it off and on again. This happens every once in a while so it wasn't a big deal until i realized the bluetooth wasn't connecting.

The issue is as such: In Bluetooth settings the device shows up as Paired. If i click it to connect, it says connecting then flashes the word connected before immediately going back to saying paired. The Bluetooth speakers do not respond at all to this. If i remove the device in an attempt to re-Pair it, the device does not show up in searches. I have unplugged the Bluetooth device and everything, but it never shows up.

However, if i turn Bluetooth searching off and on again. The device immediately shows up again as paired.
And if i remove the device completely from device manager and the control panel, it even sets up the device on its own.

Note that this happens even if the Bluetooth device i'm trying to pair with is off, or unplugged or vise versa. No matter what i do, the device will not properly be removed. I've gone into the Device manager, and removed everything. I uninstalled the bluetooth drivers and reinstalled them, i even did a registry edit in Windows NT to rollback the version to 6.2 in hopes that it would help. Nothing changed.

I did notice that if i click connect while the device is unplugged or off, it says that Windows could not connect. So when i'm trying to connect, it can tell that the device is off, but for whatever reason windows refuses to fully remove the device.

I'm on windows 10, using a Razer Blade Stealth from 2016.

Here's an image illustrating the problem.

 

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!

 

my bluetooth will not connect to my phone its saying couldnt connect

Hi

Welcome to Microsoft community.

To better help you determine the problem, could you provide your phone model as well as your computer model?

If you're experiencing issues connecting your phone to Bluetooth and it's showing an error message saying "couldn't connect," here are some steps to troubleshoot the problem:

1. Ensure Bluetooth is Enabled:
   
   • On your phone, make sure that Bluetooth is turned on.
     
2. Restart Bluetooth:
   
   • Try turning off Bluetooth on your phone and then turning it back on.
     
3. Forget and Re-pair the Device:
   
   • On your phone, go to the Bluetooth settings.
     
   • Find the device you're trying to connect to and select it.
     
   • Choose the option to "Forget" or "Unpair" the device.
     
   • Then, try pairing it again from scratch.
     
4. Check Device Compatibility:
   
   • Ensure that your phone and the Bluetooth device you're trying to connect to are compatible. Some older devices may not work well with newer Bluetooth standards.
     
5. Clear Bluetooth Cache (Android Only):
   
   • If you're using an Android device, you can try clearing the Bluetooth cache. To do this, go to your phone's settings, find the "Apps" or "Applications" section, locate "Bluetooth," and then clear its cache.
     
6. Restart Your Phone:
   
   • Sometimes, a simple restart of your phone can resolve connectivity issues.
     
7. Reset Network Settings (Optional):
   
   • As a last resort, you can try resetting the network settings on your phone, but be aware that this will also reset your Wi-Fi and cellular settings. You can usually find this option in your phone's settings under "Network" or "Reset."
     

Remember that Bluetooth connectivity problems can be caused by various factors, and troubleshooting steps may vary depending on your specific phone and device.

Please let me know if you need any further assistance. Thank you.
