[SOLVED]Bluetooth works in Win 10 but not in Linux Mint 19 Cinnamon

Post by ace_75 »

Hello Friends
I have dual boot Win 10 with Linux Mint 19 Cinnamon on Intel NUC. The Bluetooth works fine in Win 10 but not in Linux Mint. It was working fine till few days back but today I found it to be not working. It says:

Connection to BlueZ failed.
Bluez daemon is not running, blueman-manager cannot continue. This probably means that there were no Bluetooth adapters detected or Bluetooth daemon was not started.

Further info is as below:
uname -r
4.15.0-42-generic

uname -a
Linux yagya-desktop 4.15.0-42-generic #45-Ubuntu SMP Thu Nov 15 19:32:57 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux


Please guide me in this error.
Thanks in advance.

First check if the hardware of the device still is recognized :

Code: Select all

hciconfig -a
Check whether the device is blocked or not

Code: Select all

rfkill list
Check if there are some specific messages about bluetooth

Code: Select all

dmesg | egrep -i 'blue|firm'

Thanks for the reply.

It has started appearing in the panel intermittently and started functioning intermittently. I did nothing... May be there's something wrong but not completely.

Reason: Swapped the [c] tags out for [code] tags; the code tags retain some formatting that makes your output easier to read.

Some people suggest to install pavucontrol and pulseaudio-module-bluetooth and blueman Restart your computer.
