Bluetooth is shut down, then started again, very often
 
I am using UbuntuStudio 18.10 on Asus S300CA.
In the past I had issues with Linux distros and bluetooth: the adapter was recognized but after some reboots it disappeared (and sometimes to appear again) because it was like not present on the hardware.

Now I solved this issue by installing this particular distro, that in fact has not that issue, it's the first one to be useful to me as to bluetooth: the bluetooth is alsways recognized and shown on the menu bar at boot.

But every some minutes the bluetooth disappears and after some seconds it appears again. If I am using the bluetooth mouse I get aware of that because it is not responding. It is very frustrating. Similar issue with the bluetooth headphones.

I applied many suggested changes to settings, this is a very common issue, but no way.
I would like to understand why it is so difficult to solve it.
I mean it is a drastic disappearance, shut down of the bluetooth, why?
If the blueman applet is opened I see that all devices disappear and it is greyed out. The icon disappears from the menu bar.
How to check out which service is shutting down the bluetooth at regular time intervals. How to disable this useless action on my system?
Thank you in advance

And since you don't tell us what these "many suggested changes" are, what you've done/tried, or what you mean by "but no way", there's not much we can suggest.

It is called "bluetooth idle timeout", and it's used to keep bluetooth devices batteries from draining when they're not in use. You can look in the blueman settings and disable bluetooth power management.

This isn't a difficult problem to solve, and it's well documented.
