While I'm still in the process of doing in-depth research on the topic, I thought it would be beneficial to post to see if anyone has any recommendations for how to communicate between a Pi and and Arduino over Radio Frequency 433 MHz.
Looking for 2 way communication. So the Pi can send structured data (i.e. commands, more than just on/off) which can then be interpreted by the Arduino, and vice versa so data can also flow back to the Pi.
I've picked up a cheap RF Transmitter / Receiver circuit, I only have one at the moment to play with, one receiver and one transmitter, so I'll have to swap them about for testing purposes for the time being then I can build in two way communication later on.
From what I've been reading so far, RF seems quite limited which is generally used to send commands of High/Low. Is there some kind of library on either side which can turn "thisCommand(data)" into a bunch of 01010101 which can then be transmitted / received easily? I've not come across anything yet on my research, although this must exist I would have thought.
General comments / thoughts / pointers?
