# RNode Firmware
|
|
|
|
This is the firmware for [RNode](https://unsigned.io/rnode), a very flexible LoRa-based Open Communications Device.
|
|
|
|
An RNode can function as a:
|
|
|
|
- General purpose long-range data radio module
|
|
- Network adapter for [Reticulum](https://github.com/markqvist/Reticulum)
|
|
- LoRa interface for your computer (or any device with a USB or serial port)
|
|
- Generic [LoRa-based network adapter](https://unsigned.io/15-kilometre-ssh-link-with-rnode/)
|
|
- [Packet sniffer](https://github.com/markqvist/LoRaMon) for LoRa networks
|
|
- LoRa-based KISS-compatible TNC for amateur radio and AX.25 applications
|
|
- Flexible platform for experiementing with LoRa technology
|
|
|
|
To install this firmware on homebrew RNodes and other supported boards, use `rnodeconf`, the *RNode Config Utility*. For guides and tutorials on how to get started with making your own RNodes, visit [unsigned.io](https://unsigned.io).
|
|
|
|
|
|
|
|
## Get Started
|
|
|
|
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 inclueded in the `rns` package. It can be installed via `pip`:
|
|
|
|
```
|
|
# Install rnodeconf via rns package
|
|
pip install rns --upgrade
|
|
|
|
# Install the firmware on a board with the install guide
|
|
rnodeconf --autoinstall
|
|
```
|
|
|
|
## Supported Hardware
|
|
|
|
The RNode Firmware supports the following boards:
|
|
|
|
- The original RNode from [unsigned.io](https://unsigned.io/)
|
|
- Homebrew RNodes based on ATmega1284p boards
|
|
- Homebrew RNodes based on ATmega2560 boards
|
|
- Homebrew RNodes based on Adafruit Feather ESP32 boards
|
|
- Homebrew RNodes based on generic ESP32 boards
|
|
- LilyGO T-Beam v1.1 devices
|
|
- LilyGO LoRa32 v2.0 devices
|
|
- LilyGO LoRa32 v2.1 devices
|
|
- Heltec LoRa32 v2 devices
|
|
|
|
## Operating Modes
|
|
RNode can operate in two modes, host-controlled (default) and TNC mode:
|
|
|
|
- When RNode is in host-controlled mode, it will stay in standby when powered on, until the host specifies frequency, bandwidth, transmit power and other required parameters. This mode can be enabled by using the -N option of this utility. In host-controlled mode, promiscuous mode can be activated to sniff any LoRa frames.
|
|
|
|
- When RNode is in TNC mode, it will configure itself on powerup and enable the radio immediately. This mode can be enabled by using the -T option of this utility (the utility will guide you through the settings if you don't specify them directly).
|
|
|
|
## Programming Libraries
|
|
Have a look in the "Libraries" folder for includes to let you easily use RNode in your own software.
|
|
|
|
Here's a Python example:
|
|
|
|
```python
|
|
from RNode import RNodeInterface
|
|
|
|
def gotPacket(data, rnode):
|
|
print "Received a packet: "+data
|
|
|
|
rnode = RNodeInterface(
|
|
callback = gotPacket,
|
|
name = "My RNode",
|
|
port = "/dev/ttyUSB0",
|
|
frequency = 868000000,
|
|
bandwidth = 125000,
|
|
txpower = 2,
|
|
sf = 7,
|
|
cr = 5,
|
|
loglevel = RNodeInterface.LOG_DEBUG)
|
|
|
|
rnode.send("Hello World!")
|
|
```
|
|
|
|
## Promiscuous Mode and LoRa Sniffing
|
|
RNode can be put into LoRa promiscuous mode, which will dump raw LoRa frames to the host. Raw LoRa frames can also be sent in this mode, and have the standard LoRa payload size of 255 bytes. To enable promiscuous mode send the "Promiscuous" command to the board, or use one of the programming libraries. You can also use the example program [LoRaMon](https://github.com/markqvist/LoRaMon) for an easy to use LoRa packet sniffer.
