PacketMonitor is just a demonstration of what can be done with the probing
infrastructure for the radio. Unfortunately, the probing infrastructure
doesn't allow inspection of receives of individual bytes, due to the way
the CC1000 is always pumping data into the microcontroller in listen mode.
Also, because "packets" are a software-level concept (and only
approximated in the packet monitor), it might be necessary to instrument
the actual microcontroller program using the code and data probes system
to determine when the software "thinks" it has sent or received a packet.
This can be done without altering the source code of the program or the
