Bluetooth cannot find devices

[jackgreat]

Hello Guys,

I have a HP Laptop which is 1 year old only. It has build in bluetooth.

I used to use it to connect it to my Air Pods Pro. A month ago it stopped connecting. I removed the device and tried to add it again. But it would not discover it. I also tried to transfer a photo from android phone to laptop but phone wont detect bluetooth. I checked all settings and updated all drivers etc. Then I don't know how but it suddenly started working. Good. But last week again same issue has come up. All components are up to date. I uninstalled bluetooth items from device manager and windows auto reinstalled it on reboot.

Still it is unable to find any device. I did run Windows troubleshooter also but it did not help. Bluetooth does turn on/off but it doesn't work.

What to do?

Jack

Update your post to include full laptop specs and OS information.

On the laptop open Reliability History/Monitor.

Do you see any error codes, warning, or even informational events that match the pattern of events that you describe? I.e., not working, working, stopped working.

Reliability History provides a timeline format that may reveal that pattern.

Look at any entries regarding Bluetooth and/or Audio. Look for related error codes, warnings, and informational events.

You can do much the same in Event Viewer. However, Event Viewer is not as user friendly and requires more time and effort to navigate and to understand.

Hopefully there will be a few more errors or other entries appearing just before or at the times that Bluetooth stopped working.

Thank you for your reply. I did look at Reliability History but couldn't find anything related to bluetooth.

The thing is as per system the bluetooth is working because it allows me to turn it on and off and there is no error operating it. The issue is that it cannot detect any devices.

Other than the switch showing "on/off" what else is being used to determine if Bluetooth is on or off?

Try the following:

Turn Blue tooth off and look in Windows Task Manager, Resource Monitor, and Process Explorer (Microsoft, free). Use only one tool at a time.

Look for any entries or indications that Bluetooth is running.

Then turn Bluetooth on and look again. Do you see any entries or indications that Bluetooth is running?

Or any changes at all with regards to Bluetooth.?

You can also use Powershell to delve deeper via Get-PNPDevice.

Try the following link.

tl;dr how do I list in-use "bluetooth profiles". In Windows 10, I would like a listing of Bluetooth Profiles currently in-use for Bluetooth connected devices. Is there a Powershell comman...

As before, run the cmdlet with Bluetooth switched off and then again when Bluetooth is switched on.

The requirement being some indication that Bluetooth is indeed ON and proven to be working.

In the task manager (process) there is no change. I can see 2-3 windows services for bluetooth and 1 Realtek Bluetooth process as background process running.

Okay:

What do you have and what can you do to prove that the AirPods are properly functioning?

Do the AirPods work, without problems, in any other audio environment?

Wondering about those "Unknowns" - doublecheck any related driver downloads and subsequent configurations.

Do it all manually. No third party downloaders/installers.

The air pods are working. Thats why I am testing using my andriod phone as well. The android phone is a spare one and it was able to detect the air pods. However, my laptop isn't able to detect any bluetooth devices.

Does the pairing process between laptop and air pods occur without error or problems?

Earlier when it used to detect pairing happened without problems. But now its not detecting as mentioned earlier.
