@brad.s
The transceivers communicate via RF via an embedded hardware protocol. The micro-controller communicates with the transceiver module using (standard) serial communication.
Good radio communication and buffering of incoming or outgoing messages are more-or-less unaffected by clock speed of the micro-controller. So, it is not necessary to match clock speeds.
The clock speed may affect energy consumption so you will want to optimize your arduino model for its sensor application and choice of using battery or mains power. Also, your choice of 5V or 3V3 IO will affect your sensor build strategy, having to power up or down to accommodate the IO requirements of the attached devices (e.g. radio transceiver 3.3V or a pressure sensor at 5V).
Available SRAM/FLASH memory is also a factor, if you want to get into more complex devices later on.
@tbowmo Thanks for the reply. I'm still a newbie with all this. I think that I have 2.0 installed but most of the code examples I see or have used in the past are not 2.0 . Can you tell me how to install the older library and get rid of the newer one?
Basically I'd just like to be able to upload the code I've used before to the new nodes.
Ahhhh, thanks @alowhum , what you said makes so much more sense. I also see some people have attempted to stream audio with Domoticz. Ok now I have a better sense of direction on what to research next. Thank you
