Welcome to Disaster Radio Slovakia and Czech Republic

Our settings

We haved moved to RNode/Reticulum/Nomadnet/Sideband.

First install required software (sideband only if you want GUI):

pip install rns nomadnet sbapp

or macOS:

pip install rns nomadnet sbapp[macos]

Then flash:

rnodeconf --autoinstall

Answer the questions and node the device name of your device (should start with /dev/).

Then run either nomadnet or sideband. Quit. This creates default configuration files.

Edit ~/.reticulum/config and add this towards the end (I kept the ‘Default Interface’ part for context). Of course add your own device port in the ‘port =’ section:

  [[Default Interface]]
    type = AutoInterface
    ## enabled = No means we only want LoRA, so we know it's working
    enabled = No


[[RNode LoRa Interface]]
  type = RNodeInterface

  interface_enabled = True
  # Your port device here
  port = /dev/cu.usbserial-

  # Set frequency to 867.2 MHz
  frequency = 867200000
  bandwidth = 250000
  txpower = 17
  # Important: We are using spreadingfactor 10
  spreadingfactor = 10
  codingrate = 6
  flow_control = False

Who to write when testing

You can write using nomadnet to:

• j: 3008c42f9db940091f14a48c3d1cbf6f

On propagation and routing

There are two ways messages are routed. First is routing when the other node is online. You can enable this mode in .reticulum/config by setting enable_transport=True. I think this is almost always a good idea.

Another operation is propagation. This means sending a message to a propagation node, which will deliver it when the destination will become online. You can trigger the sync to a propagation node from the sidekick menu. If you want to run a propagation node, you need to run nomadnet with .nomadnet/config’s enable_node = yes. Then when sending a message, click the network icon in sideband and change direct delivery to propagation node (there is also a “qr code” option, which is paper QR code, which is a real delivery mode too!

Connect using Sideband app on your Android (and soon iOS)

You can connect to your rnode using bluetooth and use the Sideband messenger.
