Windows 10: Bluetooth deviced but unable to connect No button

Hi all,I bought a Keychron K4 recently. I used it a few times with bluetooth without any problems, when it was empty I connected it through a cable. However, when I now want to use bluetooth again, I can see that it is paired but I am unable to connect. I am using a TP link UB500. I have tried quite some things already, deleted drivers, different USB ports, removing the device, uninstalling keyboard in device manager. If I remove the device and then take the dongle out of the port and put it back in, it shows the Keychron again. It looks like the Keychron is associated to the dongle one way or

:)

 

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

 

Cannot use bluetooth device

1 Pairing is done in Settings, Devices
1.1 You click on Add Bluetooth or other device
1.2 You choose Bluetooth
1.3 If there is a pairing button on the bluetooth device itself then you press that now. You need to check the instructions for your bluetooth device to see how to do this - several automatically go into pairing mode when they switch on, others have a button that needs to be pressed for, say, 5 seconds.
1.4 The computer detects all available bluetooth devices and you select yours from the list. If yours is not on the list then Windows could not detect it.
1.5 It connects - pairing includes connecting
1.6 The computer sounds a buzz in the earpiece then displays Your device is ready to go and you click on Done
1.7 The device is shown in the devices list below the subheading Audio and it shows it as connected
1.8 The device should also appear in Control panel, Sounds, Playback tab
1.9 The device should also appear in Control panel, Devices & printers
1.10 {I just paired some bluetooth earphones as I typed so I could make sure these notes were correct} You use a music player and the sound comes out of the bluetooth earphones

2 If this is not happening for you then go to Contol panel, Devices & printers
2.1 Right-click on the device & select Remove device
2.2 You can now try pairing from scratch again
2.3 Several other users have reported that only removing the device with Bluetooth command line tools - BluetoothInstaller allowed them to re-pair again [see xzion's guidance below]
2.4 Yet others reported that only the KeithM code or Bungee's guidance worked for them [see below]

3 Where is this all going wrong for you?
[I assume we are definitely talking about bluetooth headphones/earphones. I understand that WiFi ones do also exist.]

Several people registered in TenForums just to be able to thanks xzion, KeithM & Bungee. Apparently, what worked for some people did not work for others so each solution seems worth trying.

Unable to connect devices to bluetooth

Hi,

Based on the information that you've shared, this can be caused by the Bluetooth drivers on your device. To better understand your concern, we'd like to know the following:

• If you're able to connect your headset on your device prior to disabling the built in Bluetooth adapter.
• If your computer crashes when connecting Bluetooth devices prior to disabling the built in Bluetooth adapter.
• If you've included the built in Bluetooth drivers when you've updated the device drivers.
  
• If you can see exclamation points in Device Manager. To check this, you can perform the following:
  • Search and launch Device Manager using Cortana.
  • Click on the arrow icons to show the list of drivers per category.

• The version of Windows 10 that you're using on your device. To check this, you can perform the steps posted on this
  
  link.

We look forward to your response.
