This a two node test, requires a Coordinator
and an RFD. The coordinator and node simply
ping-pong a packet back and forth, and print
out the RSSI byte. The RFD waits before
bouncing it back, while the coordinator responds
immediately.
//Basic packet sending test at the MAC level, used for internal testing only.
//This packet test has one node sending out a variety of
//differently formatted packets to two assumed destination nodes.
