====== SignalK ======

==== Connections ====

== TCP ==

Port ''8375''

Deltas sent over tcp must be entirely on one line, and terminated by ''\r\n''. (What happens if there is a solitary \n or \r in there?)

== Websockets ==

Seems to be it's preferred transport. Port as configured web interface, default ''3000'', maybe ''80'' / ''443''.

== NMEA 0183 ==

TCP port ''10110''.

== NMEA2000 ==

It can use a SocketCAN adapter, e.g. CANable/candlelight as follows;

NMEA 2000 Source: ''Canbus (canboatjs)''\\
Interface: ''can0''

=== OpenCPN ===

Recently OpenCPN has added SignalK support. It will connect to a SignalK server using the websockets protocol on (default) **port ''3000''**. You might still need to build from source to get a version that supports it.

===== Documentation =====

SignalK has pretensions to being a reïmplementable standard, and so has two sets of documentation.

  * [[https://demo.signalk.org/documentation/|Server Docs]]
  * [[http://signalk.org/specification|Specification]]

**N.B.** The specification is not entirely implemented in the server, and the server docs don't tell what doesn't conform.
