I connected a bluetooth device in windows first. Later I formated the windows partition. Now when I tried to connect the bluetooth device in Ubuntu I am not able to. I came to know we need the key generated in Windows. But I deleted windows from my machine. How can I solve this?


Edit:

Result of dmesg |grep -i blue is

Edit 2:

I added brcm/BCM43142A0-0a5c-216d.hcd file and rebooted. I could connect to my bluetooth speaker but could not play audio. I cant find my speaker in sound settings output.


Edit 3: I uninstalled blueman and rebooted and it worked.


EDIT 3:

Forget the old Windows key. when you re-pair the bluetooth device in Ubuntu, a new key will be generated.


If the bluetooth device is not even seen, maybe there is a driver problem - what bluetooth hardware/driver are you using? Please post the output of:"

dmesg |grep -i blue
