Comment 6 for bug 140668

Agreed, this is NOT a duplicate of bug #123920, I am using the laptops built in bluetooth adapter, the DiNovo gear works fine after the system has booted (but not before the login screen, as should be expected) until it has been idle for a long time, at which point it may lose the connection.

The following thread has a few people with the same issue:

I am fairly confident that they have successfully connected the devices using bluetooth, further adding to the evidence of this being a different bug.
