RFM9X Test

Note that the sub-GHz radio is not designed for streaming audio or video! It's best used for small packets of data. The

data rate is adjustbale but its common to stick to around 19.2 Kbps (thats bits per second). Lower data rates will be

more successful in their transmissions

You will, of course, need at least two paired radios to do any testing! The radios must be matched in frequency (e.g.

900 MHz & 900 MHz are ok, 900 MHz & 433 MHz are not). They also must use the same encoding schemes, you

cannot have a 900 MHz RFM69 packet radio talk to a 900 MHz RFM96 LoRa radio.

Arduino Library

These radios have really excellent code already written, so rather than coming up with a new standard we suggest

using existing libraries such as AirSpayce's Radiohead library (https://adafru.it/mCA) which also suppors a vast number

of other radios

This is a really great Arduino Library, so please support them in thanks for their efforts!

RadioHead RFM9x Library example

To begin talking to the radio, you will need to download the RadioHead library (https://adafru.it/mCA). You can do that

by visiting the github repo and manually downloading or, easier, just click this button to download the zip

corresponding to version 1.59

Note that while all the code in the examples below are based on this version you can visit the RadioHead

documentation page to get the most recent version which may have bug-fixes or more

functionality (https://adafru.it/mCA)
