modbus over RF link

Hi do anyone have idea how to send modbus data over RF link using modules like cc2500 or 433mhz RF module. Please share.

Typically, with any abstract serial protocol, the protocol should be described as a data-structure.

Then sending a structure from Arduino to Arduino, PC, smartphone, etc. Is simplified.

This should help you get started:

Modbus library

Send/Receive data structure
