Raspberry Pi Disable Bluetooth

The steps below shows how to disable on-board Bluetooth and related services. Those steps also disable loading the related kernel modules such as bluetooth, hci_uart, btbcm, etc at boot.

1 Open /boot/config.txt file.

sudo nano /boot/config.txt

2 Add below, save and close the file.

# Disable Bluetooth
dtoverlay=pi3-disable-bt

3 Disable related services.

sudo systemctl disable hciuart.service
sudo systemctl disable bluealsa.service
sudo systemctl disable bluetooth.service

4 Reboot to apply the changes

sudo reboot

Even after disabling on-board Bluetooth and related services, Bluetooth will be available when a Bluetooth adapter (e.g. Plugable Bluetooth Adapter) is plugged in.

Disable Bluetooth completely

If Bluetooth is not required at all, uninstall Bluetooth stack. It makes Bluetooth unavailable even if external Bluetooth adapter is plugged in.

1 Uninstall BlueZ and related packages:

sudo apt-get purge bluez -y
sudo apt-get autoremove -y

Uninstalling Bluetooth stack also disabling related services, and loading related kernel modules.

Raspberry Pi WinSCP as Root

By default the stfp-server of a Raspberry Pi is located at: /usr/lib/sftp-server, so we need to get WinSCP to execute it with sudo.

  • Go to your WinSCP profile (Session > Sites > Site Manager)
  • Click on Edit > Advanced… > Environment > SFTP
  • Insert sudo su -c /usr/lib/sftp-server at “SFTP Server”
  • Save and connect
