I have problem with bluetooth at Lenovo G510. I can turn on bluetooth but it can not find any device.

I tried this solution https://askubuntu.com/a/1042971/1068251, and it worked for one day. Next day Ubuntu made small update and bluetooth crashed.

Please help me to resolve this problem. If you need output from commends i can execute and place inside post.

Instruction:

lspci -knn | grep Net -A3; lsusb; dmesg | grep -i blue

gave me:
