My system is not detecting any Bluetooth device and i checked similar questions such as these - Bluetooth is not working on my laptop Ubuntu 18.04.4 LTS

None of those links helped.

I would like to know what to look for to identify whats missing at the first place. any help is appreciated

The output of lspci -knn | grep Net -A3; lsusb

dmesg | grep -i blue

  • FYI: A fully upgraded 18.04 will report itself as 18.04.5, so check you've applied all security fixes to your system, as you could be using an EOL kernel & be missing other security fixes. – guiverc Oct 13 '20 at 08:47
  • Please [edit] your question and add output of lspci -knn | grep Net -A3; lsusb terminal command. – Pilot6 Oct 13 '20 at 09:05
  • @Pilot6 - I have added the link. Unfortunately i dont have the reputation yet to post images – akash Oct 13 '20 at 10:27
  • We don't need any images. You can post terminal output as text. – Pilot6 Oct 13 '20 at 10:47
  • Please add output of dkms | grep -i blue. – Pilot6 Oct 13 '20 at 10:47
  • @pilot6 - dkms | grep -i blue ----> Error No action was specified – akash Oct 13 '20 at 11:44
  • It was a typo dmesg | grep -i blue. – Pilot6 Oct 13 '20 at 11:45
  • @pilot6 - thanks added the result to the question – akash Oct 13 '20 at 11:58
  • So its a dupe. I gave you a link how to solve it. brcm/BCM.hcd not found – Pilot6 Oct 13 '20 at 12:08
  • @pilot6 - i did check and also this - https://askubuntu.com/questions/688987/bluetooth-problem but the link is not available, the link to copy into BCM.hcd. could you tell me what to copy into BCM.hcd and what would be the destination of that file. – akash Oct 13 '20 at 12:13
  • There are a couple of answers about how to get BCM.hcd and where to copy it. There is nothing to add. All links you give are dupes. – Pilot6 Oct 13 '20 at 12:18
