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.

Hey guys,

I discovered the cause of the problem. For some reason my dongle does not start with the system.

As I discovered this:
1 - I pa**ed the controls, everything working here;
2 - The system has been restarted, the controls do not work after that.
3 - Entering by SSH and typing bluetoothctl and power on the controls come back to work.

I'm not a big connoisseur of these systems, I thought I'd make a simple script and put the power on command every time the system started.

Is there another way for me to do this?

This is weird.

Everything works perfectly. The problem to be only in saving the settings while doing the reebot.

Can someone tell me where the files are for me to try to save manually?

Hello guys,

There was a problem with my Bluetooth controls.
I have a dongle and I can configure the controls normally on the Bluez driver.

However, when you restart the system, the configuration is lost. I have to set it all up again.

Does anyone know what might be happening?
Thanks.
