Disable Bluetooth Auto-Enable Behavior via Configure file.
There’s a rule in the “/etc/bluetooth/main.conf” file in each of the three Linux distributions described above that directs it to auto-enable Bluetooth on startup. To accomplish the task, the user only needs to edit the file and disable that line.
Step 1: From the ‘Activities’ overview, look for and open the word ‘terminal’ (or start menu depending on desktop environment).
Step 2: Run the nano text editor command in the terminal to edit the configuration file.
sudo nano /etc/bluetooth/main.conf
Find and replace AutoEnable=true with AutoEnable=false once the file has opened. Finally, press “Ctrl+X,” type “y,” and press Enter to save the file.
How to Disable Bluetooth in Ubuntu
Bluetooth technology is a low-power, high-speed wireless communication link designed to connect phones and other portable devices. It is an IEEE 802.15.1 protocol for using low-power radio communications to connect phones, computers, and other network devices across short distances without the use of wires. Bluetooth transmits wireless communications over short distances, often up to 30 feet (10 meters).
Low-cost transceivers are embedded in the gadgets to do this. It operates on the 2.45GHz frequency spectrum and has a data rate of up to 721KBps, as well as three voice channels. This frequency range has been designated for the use of industrial, scientific, and medical equipment (ISM) by international agreements. rd-compatible with 1.0 devices
