A separate sniffer app could have another benefit -- precise timestamping.  If it disables
address recognition, and is the firstthing the radio does, it might be more deterministic delay.

A steady delay on recognizing a standard data packet sent for timing only purpose would let
you tune in on the exact time via round trip measurements and comparing to known time at another node.

The separate app might run as is on a non basestation node.
