I can't get Bluetooth to work in Mint 19.1, but - if works fine if I boot from a USB stick running Mint 18.3 or Mint 17.3, and it also works fine in dual-booted Win 7. So the problems doesn't seem to be related to hardware, but this specific installation of Mint 19.1

The Bluetooth device manager doesn't discover Bluetooth devices nor can a name be assigned in the settings. So how can Mint 19.1 be tweaked to get Bluetooth working?

Install updates, I think that Bluetooth was fixed in a newer 4.15 kernel

There was an issue with that 0cf3:3004 bluetooth device as Qualcomm Atheros used the same ID on 2 different bluetooth chipsets and a commit that broke your bluetooth was https://git.kernel.org/pub/scm/linux/ke ... 2c2625adb6 and you can see the ID went from being ath3012 to QCA Rome and the commit that fixed it was https://git.kernel.org/pub/scm/linux/ke ... c7de6378cb which is confusing to people not familiar with linux kernel source code

That did the trick.

Upgrade the kernel from 4.15.0-20 to 4.15.0-55.

Thanks much! :wink:
