If this icon is not present, you may need to reboot using the following command:-
sudo reboot
8. Open a terminal window on the Raspberry Pi, and type in the following commands:-
sudo apt install bluetooth
sudo apt install blueman bluez python-gobject python-gobject-2
sudo reboot
as with step 6, if you find that the apt command does not work, use apt-get instead:-
sudo apt-get install bluetooth
sudo apt-get install blueman bluez python-gobject python-
gobject-2
sudo reboot
9. After this reboot, you should notice a second Bluetooth icon in the taskbar. If you
hover your mouse over one of the Bluetooth icons, you should see the text ‘Manage
Bluetooth devices’. This is the icon that you should use to add your Bluetooth
keyboard.
