This is the community maintained fork of the open firmware which powers RNode devices. It has been created to continue to expand development and support for more hardware devices, as the upstream repository is no longer accepting PRs for new hardware support. The original repository by Mark Qvist can be found [here](https://github.com/markqvist/RNode_Firmware).
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).
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.
You must have at least version `2.1.3` of `rnodeconf` installed to update the RNode Firmware to version `1.72`. Get it by updating the `rns` package to at least version `0.6.4`.
It's easy to create your own RNodes from one of the supported development boards and devices. If a device or board you want to use is not yet supported, you are welcome to [join the effort](/CONTRIBUTING.md) and help create a board definition and pin mapping for it!
The RNode design is meant to flexible and hackable. At it's core, it is a low-power, but extremely long-range digital radio transceiver. Coupled with Reticulum, it provides encrypted and secure communications.
Depending on configuration, it can be used for local networking purposes, or to send data over very long distances. Once you have an RNode, there is a wide variety of possible uses:
RNodes can be made in many different configurations, and can use many different radio bands, but they will generally operate in the **433 MHz**, **868 MHz**, **915 MHZ** and **2.4 GHz** bands. They will usually offer configurable on-air data speeds between just a **few hundred bits per second**, up to **hundreds of kilobits per second**. Maximum output power will depend on the transceiver and PA setup used, but will generally lie between **17 dbm (50mW)** and **27 dBm (500mW)**.
The RNode system has been designed to allow reliable systems for basic human communications, over very wide areas, while using very little power, being cheap to build, free to operate, and near impossible to censor.
While **speeds are lower** than WiFi, typical communication **ranges are many times higher**. Several kilometers can be acheived with usable bitrates, even in urban areas, and over **100 kilometers** can be achieved in line-of-sight conditions.
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](https://unsigned.io/rnode_bootstrap_console), which is hosted locally on every RNode, and can be activated and accesses at any time - no Internet required.
The designs, guides and software stored within allows users to create more RNodes, and even to bootstrap entire communications networks, completely independently of existing infrastructure, or in situations where infrastructure has become unreliable or is broken.
The production of one particular RNode device is not an end, but the potential starting point of a new branch of devices on the tree of the RNode system as a whole.
This tree fits into the larger biome of Free & Open Communications Systems, which I hope that you - by using communications tools like RNode - will help grow and prosper.
You can download and flash the firmware to all the supported boards using [rnodeconf](https://github.com/markqvist/Reticulum). All firmware releases are handled and installed directly through the `rnodeconf` utility, which is included in the `rns` package. It can be installed via `pip`:
For more detailed instruction and in-depth guides, you can have a look at some of these resources:
- Create a [basic RNode from readily available development boards](https://unsigned.io/guides/2022_01_25_installing-rnode-firmware-on-supported-devices.html)
- Follow a complete build recipe for [making a handheld RNode](https://unsigned.io/guides/2023_01_14_Making_A_Handheld_RNode.html), like the one pictured above
- Learn the basics on how to [create and build your own RNode designs](https://unsigned.io/guides/2022_01_26_how-to-make-your-own-rnodes.html) from scratch
If you would like to see support added for a board which you possess, you may donate it to myself, Jacob Eva, so that I can implement support for it into this project. There will be no official timescale given for implementation however, but I will try my best when I have time :) Please [contact me (scroll to the bottom)](https://liberatedsystems.co.uk/about) if you wish to donate hardware to the project.
### Purchasing products
You can support the development of the RNode Firmware CE project by purchasing RNodes (to come in the future) and other products from [Liberated Embedded systems](https://liberatedsystems.co.uk), my online business. For more information on my business, please see [here](https://liberatedsystems.co.uk/about/).
From time to time the creator of the [Reticulum](https://reticulum.network) project, Mark Qvist, produces his own RNodes and sells them through his [shop](https://unsigned.io/shop). You may support the development of open, free and private communications systems through purchasing these from him.
I, the maintainer of this fork, am currently not accepting monetary donations. These are instead better directed to [Mark Qvist](https://unsigned.io), who created the original repository this one is based on, and is the core developer of the [Reticulum](https://reticulum.network) project, which is what the RNode Firmware was designed to supplement as a network adapter.
You can help support the continued development of open, free and private communications systems by donating to him via one of the following channels:
You can obtain the source code from [my business Git instance](https://git.liberatedsystems.co.uk/jacobeva/RNode_Firmware_CE) or [GitHub](https://github.com/liberatedsystems/RNode_Firmware_CE).
Every RNode which supports the console functionality also includes an internal copy of it's own firmware source code, that can be downloaded through the [RNode Bootstrap Console](https://unsigned.io/rnode_bootstrap_console), by putting the RNode into Console Mode (which can be activated by pressing the reset button two times within two seconds).
The RNode Ecosystem is free and non-proprietary, and actively seeks to distribute it's ownership and control. If you want to build RNodes for commercial purposes, including selling them, you must do so adhering to the Open Source licenses that the various parts of the RNode project is released under, and under your own responsibility.
If you distribute or modify this work, you **must** adhere to the terms of the GPLv3, including, but not limited to, providing up-to-date source code upon distribution, displaying appropriate copyright and license notices in prominent positions of all conveyed works, and making users aware of their rights to the software under the GPLv3.
