On an Acer V3-574-7481 with built-in stock Intel 7265 wireless hardware, WiFi works perfectly but Bluetooth does not. The System Settings applet reports "No Bluetooth adapters found" and the option to enable Bluetooth is grayed out. However, Bluetooth hardware is reported by "dmesg" and a firmware patch file is applied automatically during boot.

Bluetooth works on this same machine booted into Windows 10. The machine is dual-boot from separate partitions.

This behavior was identical first under Ubuntu 16.04 and then under 16.10 after upgrade. Command and response examples above are under 16.10 after upgrade.
