Optimized High Speed Driver for nRF24L01(+) 2.4GHz Wireless Transceiver

@tableofcontents

Design Goals

This library fork is designed to be...

More compliant with the manufacturer specified operation of the chip, while allowing advanced users to work outside the recommended operation.
Utilize the capabilities of the radio to their full potential via Arduino
More reliable, responsive, bug-free and feature rich
Easy for beginners to use, with well documented examples and features
Consumed with a public interface that's similar to other Arduino standard libraries

See the releases' descriptions on the library's release page for a list of changes.

Important

There's going to be major changes in v2.0. As of v1.5, there is newer API that should be used instead of the @ref deprecated "deprecated API".

See our migration guide to understand what you should update in your code.

RF24Network: OSI Network Layer for multi-device communication. Create a home sensor network.
RF24Mesh: Dynamic Mesh Layer for RF24Network
RF24Ethernet: TCP/IP Radio Mesh Networking (shares Arduino Ethernet API)
RF24Audio: Realtime Wireless Audio streaming
nrf_to_nrf: OSI Layer 2 radio driver for NRF52x radios. Replaces RF24 layer for new radio devices.
RF24G: Create a true mesh of up to 7 nrf24l01 and/or nrf52x devices
