I've been trying to find the answer to my problem for a month now.. There are MANY posts all around, but none solved my problem, which I still could not understand why (reason why I come here). Here it is:

My laptop has an Intel 7260 wifi+bluetooth. Wifi works fine, but I can not pair my Microsoft 3600 bluetootth mouse with it on Ubuntu 16.04... However It does work with Ubuntu 16.10!

Because of that, I immediately tough that by upgrading to kernel 4.8 on Ubuntu 16.04, that I would solve my issue, but it did not solve.

Tried using the UI, and blurtoothctl. None works. The process of pairing seems to go fine, the mouse LEDs blink as if it was normally paired, but in the end it doesnt move. What I've noticed is that dmesg shows this error after it fails to pair:

Bluetooth: SMP security requested but not available

So I guess it may be related to that. I also tried to compare the versions of drivers between 16.10 and 16.04, but they are all the same. Have no clue what to do. Follows some logs:

Now I'm running kernel 4.8.0-36 on Ubuntu 16.04

Thanks in advance!

  • I've tried it... I can not set anything through hciconfig for some reason. I get: ~ $ hciconfig hci0 sspmode 1 Can't set Simple Pairing mode on hci0: Operation not permitted (1) ~ $ sudo hciconfig hci0 sspmode 1 Can't set Simple Pairing mode on hci0: Input/output error (5) – tronic Feb 14 '17 at 1:06

I've managed to make it work. It is simular to this but it did not work with sspmode at first. So I tried doing this before pairing using the GUI, and it worked.

$ sudo hciconfig hci0 down
$ sudo hciconfig hci0 up
$ sudo hciconfig hci0 noauth

    Confirming this to work with Ubuntu 16.04 and Logitech M720 Triathlon. Thanks – Kos Prov May 21 '18 at 8:29
