I'll have to pull out my old Bluetooth test program I wrote a while ago,
then I should be able to control the streams pretty nicely (or at least
stream packets continuously with the same payload). Then I can just tune the
GNU Radio GMSK receiver (hack it for the access code correlation) to a
specific frequency and wait till I get a hit.

It's like fishing for RF. Do I have to throw them back?
