Bluetooth not Working on Kali Linux

Question

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

aptitude install bluetooth

and then run

/etc/init.d/bluetooth start

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

● bluetooth.service - Bluetooth service

My computer is a sony VAIO SVF15A17CLV.

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 its always off. After I press start it stays like the following image:

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

Answer 1

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.

Answer 2

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.

Answer 3

This link may help you. I tried and my bluetooth was on after restart too..

Answer 4

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
