bluetoothd is a daemon (background service) in Linux that is responsible for managing Bluetooth devices and settings on the system. bluetoothd is a part of the bluez package, which is a suite of tools and libraries for managing Bluetooth devices on Linux systems.
bluetoothd is usually started automatically when you boot your Linux system and runs in the background, listening for incoming Bluetooth connections and managing the Bluetooth devices on the system. You can use the bluetoothctl command to interact with bluetoothd and manage your Bluetooth devices and settings.
If you encounter the below error while running the bluetoothd command:
