Well I had the problem that bluetooth was always off. I go to configuration->Bluetooth and everytime I tried to put it off just returns to off a while after. I tried with this command:

aptitude install bluetooth

and then ran

/etc/init.d/bluetooth start

after that I ran /etc/init.d/bluetooth status and this is what shows:

● bluetooth.service - Bluetooth service

Thank you!!

Edited: After running the service restart command some of you suggested I got the following output:

Seems better but it is still not working. When I go to bluetooth settings it's always off. After I press start it stays like the following image:

Bluetooth settings turned off

PS: I know is not a hardware issue because if I boot with windows 10 it works properly.

I believe we were having the same problem. My Bluetooth would not turn on and would remain in the off position. Here is what I did to fix this problem:

service bluetooth restart

This restarted the Bluetooth service and I was able to turn it on and it stay on. I was also able to see Bluetooth devices and connect to my headphones again.

I had the same problem a few minutes ago, until I restarted the Bluetooth service from the terminal as a root user. I fix it by by typing on the terminal:

sudo service bluetooth restart

On systemd systems:

sudo systemctl restart bluetooth

Then go back to settings and under bluetooth menu, you will have the available devices.

I did the following to fix the issue.

I started with a service restart:

 $ sudo service bluetooth restart

Then system control restart:

 $ sudo systemctl restart bluetooth

Went to the bin directory:

 $ cd //bin

Then ran the service file as an exec found in bin

 $ sudo ./bluetoothctl

With bluetoothctl, use terminal commands in blutoothctl to scan (by turning it on)

 $ scan on

Then connect the device (use the digit ID of the device without the name, copy and paste is quick):

 $ connect 00:00:00:00:00

*Note, double check rfkill and make sure it is unblocked. If blocked the following (assuming bluetooth ID is listed as device 0) will unblock it:

 $ sudo rfkill unblock 0

I've made a little newbie script to get Bluetooth on your device automated.

  • Open Leafpad and copy&paste this text and save as bt without extension e.g., .sh or anything else into the folder /bin.

  • Go to the folder /bin/ and look for bt.  Right-click the file, choose propereties, and make the file executable.

  • Then open terminal @root and type bt.

and you're good to go. 

#!/bin/bash   


if [ $(id -u) != "0" ]; then
    echo
    echo -e "!! You need to be logged in as \e[101m"!!Superuser!!"\e[0m" "\e[39m to run this script !!" >&2 "\e[0m" 
    echo
exit 1
fi
read -p "Are you sure you want to start Bluetooth y/n ? " -n 1 -r
    echo    
    if [[ ! $REPLY =~ ^[Yy]$ ]]
    then
    [[ "$0" = "$BASH_SOURCE" ]] && exit 1 || return 1
fi
    echo
    echo -n
    read -t 1
    echo -n -e "\e[39m"!! Starting "\e[34m \e[5m"Bluetooth "\e[25m \e[39m"Manager !!"\e[0m"

For me, starting the service worked.

/etc/init.d/bluetooth start

I was able to find the bluetooth device and connect.
Then I had tried to enable it using 

bluetooth manager / bluetooth adapter - no go
service was not running for me.

Run sudo systemctl enable bluetooth this will add the service bluetooth to the startup process even after reboot you can do this with other system services.

1.) root@a:~# sudo /etc/init.d/bluetooth status

2.) root@a:~# sudo /etc/init.d/bluetooth start

then after that you can go setup your Bluetooth. I hope this helps

Dell Inspiron 15 3537 running Kali

First i updated the bios version to A12.

It took me couple of days figuring out and breaking my head, but finally it worked for me

I assumed that mere starting the service didn't get BT to work. While checking it's status it was active (running), but in the above line it printed disabled .

# systemctl enable bluetooth.service
# systemctl start bluetooth.service

There are many reasons which may cause such issues and sometimes restarting the Bluetooth services simply solve the problem. Run: sudo service Bluetooth restart and you will able to connect with your Bluetooth devices now. Also I have seen that this problem causes again and again sometimes after day for that I have created a alias for it in .bashrc or .zshrc file which you may be using like alias bt = 'sudo service bluetooth restart'.

Then whenever I face such issue I just have to run bt in terminal to solve it.
