RadioLib

One radio library to rule them all!

Universal wireless communication library for embedded devices

See the Wiki and FAQ for further information. See the GitHub Pages for detailed and up-to-date API reference.

RadioLib allows its users to integrate all sorts of different wireless communication modules, protocols and even digital modes into a single consistent system. Want to add a Bluetooth interface to your LoRa network? Sure thing! Do you just want to go really old-school and play around with radio teletype, slow-scan TV, or even Hellschreiber using nothing but a cheap radio module? Why not!

RadioLib natively supports Arduino, but can run in non-Arduino environments as well! See this Wiki page and examples/NonArduino.

RadioLib was originally created as a driver for RadioShield, but it can be used to control as many different wireless modules as you like - or at least as many as your microcontroller can handle!

The list above is by no means exhaustive - RadioLib code is independent of the used platform! Compilation of all examples is tested for all platforms officially supported prior to releasing new version. In addition, RadioLib includes an internal hardware abstraction layer, which allows it to be easily ported even to non-Arduino environments.
