Bluetooth is undiscoverable!

I am Mac. I have a challenge with my Bluetooth which cannot be discovered by my other devices. I upgraded from Windows 8.1 to 10 in June. Before then I had no problems with uploading or downloading files via bluetooth betwwen my devices and my laptop. After my upgrade to Windows 10 I had no problems for about two weeks. I went to settings to turn bluetooth on and the message would indicate that it is on but despite this my other devices would not pair with the laptop. A click on the extreme right would indicate that bluetooth is not on. When I click on it, it turns on and off again to show it is not on. When I check on the control manager I would find that it is on! But still no communication. After uninstalling it it would not re-install. I have tried all sorts of advices online without success. I am currently running Widows 10.
