How can Rpi communicate with Arduino in RF (Radio Frequency)?

Question

I need to transmit and receive data between Rpi and Arduino, in RF (Radio Frequency).

I must say I have next to zero experience in this field. So any help, papers, documentation, book or manual would be much appreciated.

Actually I don’t have a clue where to start. I hope to get all necessary information including the following:

(1) RF communication protocol, tutorials, libraries, and demo programs,

(2) RF modules to use for my RF project.

certain RF modulation … that means specific RF modulation ….. why did you not say which RF modulation you are talking about? — jsotola, 4 hours ago
Hello @andromeda1912, Welcome and nice to meet you. Ah, let me see. First of all, I like your question very much, because it is sort of brainstorming for innovative, IoT projects starting up, ideas on a broad area, yet narrowing down to RF, Rpi, Arduino. Usually I would suggest to zoom out to the “forest”, then in to “trees”, then in to the wood: “RF, Rpi, Arduino”. I would suggest that we get started by reading a future proof, wide angle view white paper, . to continue, … — tlfong01, 2 hours ago
Actually there are too many good white papers out there, so I usually first wiki and google, search keywords like “RF”, “MCU”, and the names of the big guys. My short list include the following, which I think should be a good read: “Connect Your MCU – Øivind Loe, Senior Product Manager – MCU and Sensors, Silicon Labs, 2020feb”: silabs.com/whitepapers/connect-your-mcu. Happy reading, Cheers. — tlfong01, 2 hours ago

Answer

For poor IoT hobbyists like me, I would suggest to start with:

(1) BLE (2.4GHz),

(2) NFC (13.56MHz), and

(3) 5G (452.5 ~ 467.5MHz, 700MHz~ 2.2GHz)
