Method: Bandshell.read_network_config

Defined in:
lib/bandshell/netconfig.rb

.read_network_config ⇒ Object

Read a JSON formatted network configuration from the config store. This instantiates the connection and addressing method classes and returns the instances i.e. cm, am = read_network_config

If no configuration is saved or it is corrupt this returns a default configuration that is somewhat likely to work.
