Whoa, this must be relatively recent. As recently as 6 months ago, the instructions on your website explicitly said that if you had a Dropcam you had to plug into USB. I desperately tried to find another option to no avail.
There is a distinction between original Dropcam/Dropcam HD setup and Dropcam Pro setup -- may be part of the confusion? Dropcam Pro had BLE setup, previous versions did not and require USB setup.
