# Description
NMEA0183 multiplexer (and tools), written in python (python3).
Comes with a lib that make it easy to connect to NMEA0183 servers and to send NMEA sentences.
Reading/Filtering NMEA sentences is also possible.
# External tools
The following scripts/libs are required:
* python3 + pip3 (python3-pip or dev-python/pip package)
* geographiclib: pip3 install geographiclib
* A C compiler for the grib tools
# Current content of the repository
"/bin" contains
---------------
* A "multiplexer" can be used to connect several NMEA0183 clients.
* A "joiner" connects a mutiplexer (or any NMEA server) to another multiplexer or server (one way).
* A "pipe" connects a mutiplexer (or any NMEA server) to another multiplexer or server (bi-directional).
* A "console" can be plugged-in on the multiplexer to monitor live NMEA0183 traffic.
"/lib" contains
