What the best way to capture the payload within an 802.15.4 frame for
processing on a PC?

I am receiving IEEE 802.15.4 frames from an embedded device and I can see
them with my packet sniffer.
I am trying to feed this stream of frames into a LabView program but I'm
not sure what the best way to do this would be.
How can I get a labview program to continuously read the live stream of
802.15.4 frames and parse out the payload?
Can I use the packet sniffer itself?
