PJON_ASK – Radio multimaster communications bus system for Arduino

In plain words

PJON_ASK is a radio communication protocol for Arduino and IoT devices that enables multiple devices to share a single communication bus using ASK/FSK modulation. It allows Arduino boards and connected systems to exchange data wirelessly in a multimaster configuration where any device can initiate communication. The codebase is now obsolete and users are directed to use PJON, the successor project, for current development.
