The NB10 ships with an Atheros QCA9565/AR9565 mini-pcie card, which is a combined wireless ethernet and bluetooth device.
The ar9565 (wlan) part works out-of-the-box.
In Debian jessie, the qca9565 (bluetooth) controller requires that the “firmware-atheros” package be installed. Before this is done, an error like this will be seen from the kernel on boot:
usb x-y: firmware: failed to load ar3k/AthrBT_0x31910000.dfu (-2) usb x-y: firmware: Direct firmware failed to load with error -2
and “hcitool dev” will show no devices. In this state the bluetooth icon (from the bluetooth-applet program) will not appear on the desktop and the system will appear to not have bluetooth connectivity.
So long as the “bluetooth” and “bluetooth-gnome” packages are installed, this is all you need; the blueooth icon will then appear in the GNOME notification area and bluetooth apps & devices will be available as normal. If you don’t use Blueooth it should probably be disabled for security reasons.
This device is relatively new and kernel support for it is quite modern. Older distributions/kernels may have more trouble. This works for me using 3.14rc7.
Powertop’s power consumption measurement is only a rough measure, but it suggests there’s no impact on power consumption from loading the bluetooth driver. There will obviously be some impact if bluetooth connectivity is used.
