How it works

After buy a new bluetooth usb dongle, I noticed it was very difficult to make it connect to my headphones, also noticed if I restart the bluetooth service and try to connect sometimes it will work at some moment, so what I did was jut automate this process.

About the bluetooth issue root cause:

I wasn't able to find a real fix for the bluetooth problem, looks like it doesn't even exist, all people advise to buy a new hardware at the end, then I made this program as a workaround.
