So I still haven't been able to figure this out and found tons of other people with various combinations of wireless intel cards / OS having the same or similar issues with bluetooth.
I have:
- an intel nuc (newest bios #35)
- an intel ac3160 wifi/bluetooth card
- ubuntu 14.04 (newest kernel 3.18)
- iwlwifi-3160-10.ucode firmware
Bluetooth seems to work, I can put it on, I can select a device (a bluetooth speaker in this case) but after a second or so the connection goes back to "off" automatically.... So pairing does work, but it can never be selected as sound output.
Why doesn't this work and can I get it to? Maybe I should just buy an external bluetooth usb drive but it just annoys me intel hasn't been able to address this.
