I'm using a Dell Inspiron N5030 laptop and want to connect my Bluetooth speakers (Ultimate Ears). Here some outputs:

One thing I've noticed is that the bluetooth service is disabled after every reboot. I have to run sudo modprobe btusb and sudo systemctl restart bluetooth every time. Is there a way to start it automatically?

Another thing: My BIOS version is A02, but from 09/13/2010. There is one from 2011. Could this be a problem?

With Linux Mint:

mint@mint:~$ hcitool dev

  • 19.1 was released yesterday I see, that's Ok, Cinnamon preferably. – LinuxSecurityFreak Dec 20 '18 at 5:26
  • I'm going to do it tonight and let you know. Thanks so far! – Thrash Dec 20 '18 at 5:29
  • No problem, you're welcome! See you later. – LinuxSecurityFreak Dec 20 '18 at 5:30
  • What's the output of "hcitool dev" ??? – wef Dec 20 '18 at 6:38
  • I've tried it now with Linux Mint, still the same outputs. There is no real output of hcitool dev (see above). – Thrash Dec 20 '18 at 22:39

I had a similar issue with a dell xps 9370, and I could solve it with this:

sudo add-apt-repository ppa:canonical-kernel-team/ppa
sudo apt-get update
sudo apt-get install linux-oem-osp1 

Which installed the following kernel:

Linux xps 5.0.0-1050-oem-osp1 #55-Ubuntu SMP Fri Apr 24 11:08:25 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
