I have a problem with sharing any file via bluetooth to my laptop. After choosing bluetooth in sharing menu my laptop does not show up neither in paired nor unpaired devices section. And transfer fails immediately. Normally in settings-device-bluetooth laptop is shown succesfully. This is second time i am having this problem. At first after rebooting/pairing/unpairing too many times the problem had gone.

Do you have any idea about the cause of this problem?

The screenshots are below. In first screenshot my device shows up in settings menu well. But in second one it does not.
