Index Of How To Deactivate Bluetooth of Raspberry Pi
Background
Whilst I do not know why you like to permanently deactivate the Bluetooth on Raspberry Pi, there are 5 reasons that come to mind that could make you think to turn Bluetooth off:
- Bluetooth consumes energy: Bluetooth consumes energy, and if your Raspberry Pi is running on battery power or in an energy-efficient project, disabling Bluetooth can significantly extend battery life.
- Security Considerations: Disabling Bluetooth minimizes potential security risks. Attackers could exploit Bluetooth vulnerabilities to gain unauthorized access or execute malicious code.
- Stability: Avoid interference: In crowded environments or areas with multiple Bluetooth devices, interference can affect performance. Disabling Bluetooth ensures a stable connection.
- Resource Optimisation: Free up system resources: Even when idle, Bluetooth modules use memory and CPU cycles. Disabling Bluetooth ensures these resources are available for other tasks.
- Simplified Configuration:Ethernet-only setups: If your Raspberry Pi is always connected via Ethernet, disabling Wi-Fi and Bluetooth simplifies network configuration and ensures consistent connectivity.
Permanently Deactivate Bluetooth of Raspberry Pi
- Login into your Raspberry Pi by leveraging SSH. Once done, fire the below command:
vi /boot/config.txt
Within this file, add at the end into the section of [all] the below line:dtoverlay=disable-bt
- Reboot the system by
sudo reboot
Additional Information
To also deactivate Bluetooth, do exactly the same like in the above, but add additionally in /boot/config.txt the following line at the end:
dtoverlay=disable-wifi
