How do you get N2K AIS data from signal K into Navionics

[duncancw01]

Hi,

I'm having a problem getting my AIS data that I've managed to get into Signal K via my NMEA2000 network, being seen by Navionics.

I have an AIS transponder and I can see the AIS data coming into Signal K and subsequently OpenPlotter using NMEA2000 on the CAN bus interface on my raspberry Pi 4b. I want to be able to send that data out via the Wi-Fi interface on my raspberry Pi so that the AIS data can be seen on my mobile devices that run Navionics.

Navionics only recognises the data in NMEA1083 format and not N2K. I have therefore installed the signal K to NMEA1083 plugin. Although I haven't been able to specifically select AIS data on the plugin, as there doesn't appear to be an option for that.

I have also set up my Wi-Fi as a Access Point (AP) and on my mobile devices running Navionics (both Android) I can connect to the AP.

When I go into Navionics and try to 'Pair the Devices' using the name of the AP and IP address (default 10.10.10.1) and port name (default 10110) of the NMEA1083 server, i.e. the signal K NMEA1083 server, it doesn't connect. It's greyed out and just won't connect.

Any ideas what I'm missing, or haven't done correctly?

Many thanks

TL;DR: AIS is a special case, you need to install the signalk-n2kais-to-nmea0183 plugin and activate it.

Longer: While the conversions in the signalk-to-nmea0183 plugin work by converting Signal K data (from any source) to 0183 it makes more sense to convert incoming NMEA2000 AIS data directly to 0183, because the messages map one to one there.

But it sounds like there's something else troubling your Navionics connection, as the connection should connect anyway. With no conversion from N2K to 0183 there just would not be any AIS data there. My Navionics subscription has expired, so I can't verify the exact settings. Just make sure that you're using TCP, not UDP, as that is what the default 0183 serviceon port 10110 is using.

Thanks tkurki

I will install the signalk-n2kais-to-nmea0183 plugin.

My devices do connect to the AP but it is frustrating that Navionics is not pairing with the signal K service. I can confirm that I've been using the TCP and not UDP and the address is 10.10.10.1 on port 10110

Hi, have you managed to get this ais overlay navionics yet?
