When connected to the current Blunami app, the BlueRailTrains DCC module when coupled with a DCC decoder will allow access and revisions to all CV's embedded in the DCC decoder. When the Blunami app is connected to a Blunami decoder, in addition to the standard access to CV's, there are a number of shortcut icons which provide quick access to a number of the more commonly user programmed CV's. This is a highly user friendly feature.
