Bluetooth on and available but no devices found

I just installed the bluetooth 4.0 LE adapter into my Windows 10 pc. The blue light flashes 1 time and goes out. In settings, Bluetooth shows on and searching for devices. No devices are found when there should be multiple available. I’ve tried several usb ports with same result - any help appreciated

Hi Don,

Thank you for contacting us about your Bluetooth adapter. I’m sorry for the troubles getting it working.

I would like to take a look at the situation of the drivers. Could you run our diagnostic program? It will gather device information and installation logs that will help me understand what is happening.

To do this, please plug the adapter into your computer, then go to this page, and follow the instructions there:

When you run the program, it will create a zip file on your desktop with your computer name and the date. Please send that file directly to our support email at

Please put “For Ticket #169172” in the subject line.

Of course it it turns out something is wrong with the adapter, we will get a replacement out to you right away.
