#hmm: need two addresses for legacy - use a tuple (house_address, index)
#unless we have an adaptor class for air_interface which represents the
#collective house address for a house code. So if you use more than one
#house address, you create multiple air interface adaptors with different
#house codes, that just delegate to the same actual radio air interface?
#bit like a little local router?
#legacy1 = AirInterface.create("OOK", address=0xC8C8C, energenie_radio)
# Could also consider this a local network, with common parameters shared
# by all devices that use it.
#air2 = AirInterface.create("FSK", energenie_radio)
# scheduling would then become
# scheduler = Scheduler(energenie_radio)
# legacy1 = AirInterface.create("OOK", address=0xC8C8C, scheduler)
# air2 = AirInterface.create("FSK", scheduler
# so that when a device tries to transmit, it gets air interface specific
# settings added to it as appropriate, then the scheduler decides when
# to send and receive
# Somehow we need to associate devices with an air interface
# This might allow us to support multiple radios in the future too?
#legacy1.add(tv)
# cooperative loop could be energenie_radio.loop()
# or wrap a thread around it with start() but beware of thread context
# and thread safety.
