Ok, in a way that's good news then. It's definitely communicating with your BLE dongle, and seeing the Pucks.
Have you been able to update the firmware on your Pucks yet? The 1v88 version of the firmware doesn't advertise very often, and could potentially be causing the connection issues (although it should work after a few tries).
