/*

LoRa Duplex communication with callback
|
||||
context: Arduino
|
||||
|
||||
This sketch is for testing transmission between two devices, one an Uno,
|
||||
and one not an Uno (a MKRZero, in my case). The #defines are there for that
|
||||
reason,and should be removed before making this a real example.
|
||||
|
||||
It sends every half second, and polls continually for new packets.
|
||||
|
||||
There's a block that's commented out in the loop that lets you change the
|
||||
sync word on one device, to test sync address filtering. The SyncWordTest.xslx
|
||||
spreadsheet shows some typical results.
