If you are running Kali Linux and your Bluetooth is not working. Let’s fix that. It will be up and running in no time.
First of all, open a terminal window.
then type this command
sudo lsmod | grep bluetooth
This will search for “bluetooth” in the lsmod.
Now you need to enable bluetooth using
systemctl enable bluetooth.service
Now start the bluetooth service using
systemctl start bluetooth.service
And that’s it. Now your PC’s Bluetooth should be working.
