        print('[!] Scanning for active devices...')
        print(f"[!] Found {len(discovered_devices)} Devices\n")

        # Iterate through discovered devices and print their details.

    except Exception as e:
        # Handle and display any exceptions that occur during device discovery.

# Call the Bluetooth device scanning function when the script is run
