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 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!

First of all, take a look at the examples and the Wiki - especially the Basics page. There's a lot of useful information over there. If something isn't working as expected, try searching the issues.

The fastest way to get help is by creating an issue using the appropriate template. It is also highly recommended to try running the examples first - their functionality is tested from time to time and they should work. Finally, RadioLib is still under development, which means that sometimes, backwards-incompatible changes might be introduced. Though these are kept at minimum, sometimes it is unavoidable. You can check the release changelog to find out if there's been such a major change recently.

Start by creating new issue (if it doesn't exist yet). If you have some experience with microcontrollers and C/C++ in general, you can try to add the support yourself! Use the template files in /extras/ folder to get started. This is by far the fastest way to implement new modules into RadioLib, since I can't be working on everything all the time. If you don't trust your programming skills enough to have a go at it yourself, don't worry. I will try to implement all requested modules, but it will take me a while.
