Very well guys,
I was able to solve my problem.
I feel happy because I do not have great knowledge of this area, only determination.
After finding the problem, quoted in the post above, I solved the problem by putting a command at boot:
Echo "power on" | Bluetoothctl
Every time you start the machine bluetooth devices start normally.
Sorry for my bad English and sorry for the posts in a row.
Problem solved.
