My bluetooth is open and active but not found any device

Gday @khanozai , Welcome to the community!

Can you tell us more about the bluetooth?
The make & model of the bluetooth?
Your machine spec's/make & model?

Output from lshw or inxi and either lspci or lsusb would help us.

While the make and model of your computer and Bluetooth may be apparent to you, those of us that don't know you or your configuration are at a loss to provide any insight to the issue.

Most of the time, the wifi card driver is the reason for Bluetooth not working. Having the wrong driver installed can allow one but not the other. I would start there. You can get the model of your wifi card using lshw in the terminal.

This May have a solution worth trying:

My Problem was just a naming issue :-

$ dmesg | grep -i 'bluetooth'

if you are facing some naming problem,the output of above command should be somthing like this ->

Bluetooth hci0: Direct firmware load for brcm/BCM43142A0-0489-e062.hcd failed with error -2
Bluetooth: hci0: BCM: Patch brcm/BCM43142A0-0489-e062.hcd not found

The Problem here is in this folder : /lib/firmware/brcm

$ ls /lib/firmware/brcm/*.hcd

The above command gives output of some *.hcd file (in my case BCM.hcd).
But my kernal is looking for BCM43142A0-0489-e062.hcd.
All you need to do is make a copy and rename.

$ cp /lib/firmware/brcm/BCM.hcd /lib/firmware/brcm/BCM43142A0-0489-e062.hcd (in my case)

Restart the PC and will see the frimware is loaded.

Now you can see bluetooh is working.

Open the terminal & copy & paste the below command:

Then restart your machine & try the bluetooth.

joe@joe-Standard-PC-i440FX-PIIX-1996:~$ ls /lib/firmware/brcm

here is the details sir.

we need to see the BCM file name's like in my results

Does removing the bluetooth usb dongle wait 15sec or so, & re-plug it in help?
If not then Remove the usb dongle & run this in the terminal:

sudo apt install -f

let us know if this helped.
If not please show the results for this

sudo systemctl status bluetooth.service
