I wanna connect BlueSMiRF, a Bluetooth device, to PC, which your product has inserted in. However, although through Arduino, BlueSMiRF finds PC, they cannot establish one connection. How to do it? btw, PC cannot find BlueSMiRF.


Thank you for posting about your Bluetooth adapter.

It is hard to know what the problem is without more information about your setup and what happened during the pairing process, but I think there may be a driver issue.

Could you run our diagnostic program? It will gather device information and installation logs that will help me understand what is going on.

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 address at

Please put “For Ticket #191109” 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.
