The following inputs are supported:

• System.IO.Stream (all platforms)
• Emulation from NMEA log file (all platforms)
• Bluetooth: Windows Universal and Android. Desktop is supported using the bluetooth device via the SerialPortDevice.
• Serial Device: Windows Desktop and Windows Universal.

Currently supported NMEA messages:

The API is easily extensible with more NMEA messages. Simply create a new class inheriting from "NmeaMessage" and use the NmeaMessageType Attribute to tag it with the NMEA Message Token it supports.

Example:

[NmeaMessageType("--RMC")]
public class Rmc : NmeaMessage
{
	protected override void LoadMessage(string[] message)
	{
		//TODO: Process message parts
	}
}

If you add new messages, please fork, provide a simple unit test for the message and submit a pull request.
