+# Blueprint : Radio-Only Node, transport disabled
+# Purpose   : This confguration is a blueprint for a radio-only node
+#             that modem73 as the radio interface. If a supported 
+#             et-lora device is detected, it will be enabled, too.

+  
+  # If you enable Transport, your system will route traffic
+  # for other peers, pass announces and serve path requests.
+  # This should only be done for systems that are suited to
+  # act as transport nodes, ie. if they are stationary and
+  # always-on. This directive is optional and can be removed
+  # for brevity.
+  
+  enable_transport = False
+  
+  
+  # By default, the first program to launch the Reticulum
+  # Network Stack will create a shared instance, that other
+  # programs can communicate with. Only the shared instance
+  # opens all the configured interfaces directly, and other
+  # local programs communicate with the shared instance over
+  # a local socket. This is completely transparent to the
+  # user, and should generally be turned on. This directive
+  # is optional and can be removed for brevity.
+  
+  share_instance = Yes
+  
+  
+  # If you want to run multiple *different* shared instances
+  # on the same system, you will need to specify different
+  # instance names for each. On platforms supporting domain
+  # sockets, this can be done with the instance_name option:
+  
+  instance_name = default
+
+# You can configure whether Reticulum should discover
+# available interfaces from other Transport Instances over
+# the network. If this option is enabled, Reticulum will
+# collect interface information discovered from the network.
+
+# discover_interfaces = No
+
+
+# You can configure Reticulum to panic and forcibly close
+# if an unrecoverable interface error occurs, such as the
+# hardware device for an interface disappearing. This is
+# an optional directive, and can be left out for brevity.
+# This behaviour is disabled by default.
+
+# panic_on_interface_error = No
+
+
+# If you're connecting to a large external network, you
+# can use one or more external blackhole list to block
+# spammy and excessive announces onto your network. This
+# funtionality is especially useful if you're hosting public
+# entrypoints or gateways. The list source below provides a
+# functional example, but better, more timely maintained
+# lists probably exist in the community.
