radio transmission unreliability

Arduino Libraries

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

using existing libraries such as LowPowerLab's RFM69 Library (https://adafru.it/mCz) and AirSpayce's Radiohead

library (https://adafru.it/mCA) which also suppors a vast number of other radios

These are really great Arduino Libraries, so please support both companies in thanks for their efforts!

We recommend using the Radiohead library - it is very cross-platform friendly and used a lot in the community!

RadioHead Library example

To begin talking to the radio, you will need to download our small fork of the Radiohead from our github

repository (https://adafru.it/vgE). You can do that by visiting the github repo and manually downloading or, easier, just

click this button to download the zip

https://adafru.it/vgF

Rename the uncompressed folder RadioHead and check that the RadioHead folder contains files like RH_RFM69.cpp

and RH_RFM69.h (and many others!)

Place the RadioHead library folder in your

arduinosketchfolder

/libraries/ folder.

You may need to create the libraries subfolder if it's your first library. Restart the IDE.

We also have a great tutorial on Arduino library installation at:

Basic RX & TX example

Lets get a basic demo going, where one radio transmits and the other receives. We'll start by setting up the transmitter

Basic Transmitter example code

This code will send a small packet of data once a second to another RFM69 radio, without any addressing.

Open up the example RadioHead -> feather -> RadioHead69_RawDemo_TX

Load this code into your Transmitter Arduino or Feather!
