Documentation

PJON implements a totally software-defined network protocol stack in around 1500 lines of code, thanks to the strategies abstraction it can operate transparently on different media, physical layers and other protocols. Thanks to the interfaces abstraction PJON can be easily ported on any MCU or architecture. The graph below shows the implementation's architecture.

Strategies abstraction

PJON codebase uses strategies to physically communicate through the medium used, abstracting the data link layer from its procedure. A Strategy is a class containing the back-off configuration and a set of methods able to send and receive messages; 7 strategies are available to communicate data through various media. Take a look at the strategies video introduction for a brief showcase of their features.
