LinuxQuestions.org - Bluetooth can't find any device

Hi,

I just get Dell Latitude D8300, and install Lubuntu there. I read, that is quite good distro for old laptops.

Everything works perfectly, except Bluetooth. When I try to discover new devices, it doesn't found anything. I've 2 phones with Bluetooth and a Bluetooth speaker - Bose soundlink mini 2. No idea what's wrong.. BT is turned on in BIOS.

Here some informations:

Code:
