JML: Thanx for the HC12 info. I guess I havent spent any time looking into this
device. It's a 433 MHz transceiver as I understand it. Not sure if an antenna is required if
transmissions are to be within a large room only. I would have to attach a "wire" 83mm
antenna if I used RK24s. I am familiar to some extent with the Arduino code involved
with simple RK24 transmissions. Is HC12 code of similar complexity? Do you have
a good reference that addresses code and Arduino wiring? Thanx in advance.
As I posted earlier, transmissions will be 2 bytes to all transceivers no quicker than every
few seconds. Only transceivers "relatively" adjacent to the originating transceiver will
respond to a transmission, and that response doesnt require its own broadcast or any
return acknowledgement. I cant ever see there would be any collisions or device-busy
issues. My main problem is the control-code logic needed to operate passive devices
that comes from the affected Arduinos.
On the other hand, if a linear net of HC-05s "knew" all the UUIDs of the HC-05s in the net,
then you are telling me that any one HC-05 could broadcast to all the others one by one
serially...? Yes? That code would be simple with no feedback required to the originating
HC-05. Im thinking I could find all UUIDs using my cell phone...? Maybe this is mental mush!
