The NMEA engine of NMEAremote is based on sources and modules. As sources are delivering the messages e.g. from the boat’s network, the modules will handle the appropriate messages and assign its values to the module’s properties. In short a module is a group of relating properties. Further some properties will be calculated depending on other properties, like the true wind from apparent wind.
Some of the module’s properties could exist multiple times like the “Engine”. These properties also have a name to be identified by the user and an Instance ID which has to match to the instance of the NMEA messages.
Not all modules are existing per default. To add missing or remove unused modules, head to Settings/Modules and tap on “Edit “.
