This article will outline the general process, and provide the information you need, for building your own RNode from a few basic modules. The RNode will be functionally identical to a purchased device.
@ -30,9 +31,10 @@ Currently, the RNode firmware supports a variety of different microcontrollers,
Regarding the LoRa transceiver module, there is going to be an almost overwhelming amount of options to choose from. To narrow it down, here are the essential characteristics to look for:
- The RNode firmware needs a module based on the **Semtech SX1276**, **Semtech SX1278**, **SX1262**, **SX1268** and **SX1280** LoRa transceiver ICs. These come in several different variants, for all frequency bands from about 150 MHz to 2500 MHz.
- The RNode firmware needs a module based on the **Semtech SX1276** or **Semtech SX1278** LoRa transceiver IC. These come in several different variants, for all frequency bands from about 150 MHz to about 1100 MHz.
- Support for **SX1262**, **SX1268** and **SX1280**-based modules is coming soon, but until that is released, only **SX1276** and **SX1278** modules will work.
- The module *must* expose the direct SPI bus to the transceiver chip. UART based modules that add their own communications layer will not work.
- The module must also expose the *reset* line of the chip, and provide the **DIO0** (or other relevant) interrupt signal *from* the chip.
- The module must also expose the *reset* line of the chip, and provide the **DIO0** interrupt signal *from* the chip.
- As mentioned above, the module must be logic-level compatible with the microcontroller you are using, unless you want to add a level-shifter. Resistor divider arrays will most likely not work here, due to the bus speeds required.
Keeping those things in mind, you should be able to select a suitable combination of microcontroller board and transceiver module.

9. Connect the *DIO0* pin of the transceiver module to the *DIO0 interrupt pin* of the microcontroller board.
10. You can optionally connect transmit and receiver LEDs to the corresponding pins of the microcontroller board.
The pin layouts of your transceiver module and microcontroller board will vary, but you can look up the correct pin assignments for your processor type and board layout in the [Config.h](https://github.com/markqvist/RNode_Firmware/blob/master/Config.h) file of the [RNode Firmware](https://unsigned.io/rnode_firmware).
The pin layouts of your transceiver module and microcontroller board will vary, but you can look up the correct pin assignments for your processor type and board layout in the `Config.h` file of the [RNode Firmware]({ASSET_PATH}pkg/rnode_firmware.zip).
### Loading the Firmware
Once the hardware is assembled, you are ready to load the firmware onto the board and configure the configuration parameters in the boards EEPROM. Luckily, this process is completely automated by the [RNode Configuration Utility](https://markqvist.github.io/Reticulum/manual/using.html#the-rnodeconf-utility). To prepare for loading the firmware, make sure that `python` and `pip` is installed on your system, then install the `rns` package (which includes the `rnodeconf` program) by issuing the command:

If installation goes well, you can now move on to the next step.
The `rnodeconf` program is included in the `rns` package. Please read [these instructions]({ASSET_PATH}s_rns.html) for more information on how to install it from this repository, or from the Internet. If installation goes well, you can now move on to the next step.
> *Take Care*: A LoRa transceiver module **must** be connected to the board for the firmware to start and accept commands. If the firmware does not verify that the correct transceiver is available on the SPI bus, execution is stopped, and the board will not accept commands. If you find the board unresponsive after installing the firmware, or EEPROM configuration fails, double-check your transceiver module wiring!
@ -76,6 +73,24 @@ rnodeconf --autoinstall
The installer will now ask you to insert the device you want to set up, scan for connected serial ports, and ask you a number of questions regarding the device. When it has the information it needs, it will install the correct firmware and configure the necessary parameters in the device EEPROM for it to function properly.
> **Please Note!** If you are connected to the Internet while installing, the autoinstaller will automatically download any needed firmware files to a local cache before installing.
> If you do not have an active Internet connection while installing, you can extract and use the firmware from this device instead. This will **only** work if you are building the same type of RNode as the device you are extracting from, as the firmware has to match the targeted board and hardware configuration.
If you need to extract the firmware from an existing RNode, run the following command:
```
rnodeconf --extract
```
If `rnodeconf` finds a working RNode, it will extract and save the firmware from the device for later use. You can then run the auto-installer with the `--use-extracted` option to use the locally extracted file:
```
rnodeconf --autoinstall --use-extracted
```
This also works for updating the firmware on existing RNodes, so you can extract a newer firmware from one RNode, and deploy it onto other RNodes using the same method. Just use the `--update` option instead of `--autoinstall`.
If the install goes well, you will be greated with a success message telling you that your device is now ready. To confirm everything is OK, you can query the device info with:

This repository is a public mirror. All potential future development is happening elsewhere.
I am stepping back from all public-facing interaction with this project. Reticulum has always been primarily my work, and continuing in the current public, internet-facing model is no longer sustainable.
The software remains available for use as-is. Occasional updates may appear at unpredictable intervals, but there will be no support, no responses to issues, no discussions, and no community management in this or any other public venue. If it doesn't work for you, it doesn't work. That is the entire extent of available troubleshooting assistance I can offer you.
If you've followed this project for a while, you already know what this means. You know who designed, wrote and tested this, and you know how many years of my life it took. You'll also know about both my particular challenges and strengths, and how I believe anything worth building needs to be built and maintained with our own hands.
Seven months ago, I said I needed to step back, that I was exhausted, and that I needed to recover. I believed a public resolve would be enough to effectuate that, but while striving to get just a few more useful features and protocols out, the unproductive requests and demands also ramped up, and I got pulled back into the same patterns and draining interactions that I'd explicitly said I couldn't sustain anymore.
So here's what you might have already guessed: I'm done playing the game by rules I can't win at.
Everything you need is right here, and by any sensible measure, it's done. Anyone who wants to invest the time, skill and persistence can build on it, or completely re-imagine it with different priorities. That was always the point.
The people who actually contributed - you know who you are, and you know I mean it when I say: Thank you. All of you who've used this to build something real - that was the goal, and you did it without needing me to hold your hand.
The rest of you: You have what you need. Use it or don't. I am not going to be the person who explains it to you anymore.
This is not a temporary break. It's not "see you after some rest", but a recognition that the current model is fundamentally incompatible with my life, my health, and my reality.
If you want to support continued work, you can do so at the donation links listed in this repository. But please understand, that this is not purchasing support or guaranteeing updates. It is support for work that happens on my timeline, according to my capacity, which at the moment is not what it was.
If you want Reticulum to continue evolving, you have the power to make that happen. The protocol is public domain. The code is open source. Everything you need is right here. I've provided the tools, but building what comes next is not my responsibility anymore. It's yours.
To the small group of people who has actually been here, and understood what this work was and what it cost - you already know where to find me if it actually matters.
To everyone else: This is where we part ways. No hard feelings. It's just time.

The RNode Firmware supports all transceiver modules based on Semtech **SX1276**, **SX1278**, **SX1262**, **SX1268** and **SX1280** chips, that have an **SPI interface** and expose the relevant **DIO** interrupt pins from the chip.
The RNode Firmware supports all transceiver modules based on **Semtech SX1276** or **Semtech SX1278** chips, that have an **SPI interface** and expose the **DIO_0** interrupt pin from the chip.
Support for **SX1262**, **SX1268** and **SX1280** is being implemented. Please support the project with donations if you want this faster!
## Getting Started Fast
You can download and flash the firmware to all the supported boards using the [RNode Config Utility](https://github.com/markqvist/rnodeconfigutil). All firmware releases are now handled and installed directly through the `rnodeconf` utility, which is included in the `rns` package. It can be installed via `pip`:
