# RNode Firmware # RNode Firmware
This is the firmware that powers RNodes. An RNode is an open, free and unrestricted digital radio transceiver. It enables anyone to send and receive any kind of data over both short and very long distances. RNodes can be used with many different kinds of programs and systems, but they are especially well suited for use with [Reticulum](https://reticulum.network). This is the open firmware that powers RNodes.

RNode is not a product, and not any *one* specific device in particular. It is a system that is easy to replicate across space and time, that produces highly functional communications tools, which respects user autonomy and empowers individuals and communities to protect their sovereignty, privacy and ability to communicate and exchange data and ideas freely.

The RNode system is primarily software, which *transforms* different kinds of available hardware devices into functional, physical RNodes, which can then be used to solve a wide range of communications tasks. Such RNodes can be modified and built to suit the specific time, locale and environment they need to exist in.

## Latest Release
The latest release, installable through `rnodeconf`, is version `1.55`. This release brings the following changes:
- Added the **RNode Bootstrap Console** to all WiFi-capable RNodes. All such RNodes now contain a complete repository of information, software, guides and tools for replicating the RNode desing, and creating more RNodes.
- RNodes can now supply other RNodes with firmware images, with allows creating RNodes and bootstrapping communication networks, even if the Internet is unavailable.
- Improved RGB LED handling.
- Improved power management and charge status handling.
- Improved Bluetooth handling.
You must have at least version `2.1.0` of `rnodeconf` installed to update the RNode Firmware to version `1.55`. Get it by updating the `rns` package to at least version `0.4.7`.
## A Self-Replicating System ## A Self-Replicating System
If you notice the presence of a circularity in the naming of the system as a whole, and the physical devices, it is no coincidence. Every RNode contains the seeds necessary to reproduce the system, the [RNode Bootstrap Console](/rnode_bootstrap_console), which is hosted locally on every RNode, and can be activated and accesses at any time - no Internet required.
