Hi Ken. I do not see why you should leave PBP and start another similar language and your project all over again.

If you do need RF communication between nodes maybe a Zigbee modules or RF transceivers can give you a good solution without almost a line of code.

Look at Digi modules (Zigbee or not, does not matter) for out of he box communication. Other brands also exist, many I can say.
