Ben, No. The Database only returns spectrum for the primary device descriptor. The "master device descriptor" is for reference only when the primary device is a slave.
I.e., When the Master requests spectrum for itself, it will use the primary device descriptor. -vince On Thu, Oct 17, 2013 at 12:23 PM, Benjamin A.
