Trying to connect SignalK to USB GPS on Windows
So I have a Pansonic Toughbook CF33 wth an integral GPS which is made available on COM11. I have verified that there's a NMEA0183 stream coming through that at 4800 baud. Both OpenCPN and my own homebrew multiplexer can see and use that datastream.
Unfortunately, SignalK does not. Now I now SignalK can, so obviously it's something I'm doing wrong. here's the data source:
Note that when my multiplexer reads the stream and copies it to a TCPStream, then SignalK reads it correctly. I am trying to get rid of the multiplexer and let SignalK do that work for me....
What's needed for an entity to be shown in Freeboard
I'm working on the Meshtastic integration with Signal K (https://github.com/meri-imperiumi/signalk-meshtastic#readme), and I am populating the seen Meshtastic devices into Signal K entities of their own. If a node can be associated with a vessel, then that additional paths go there. If not, a separate
meshtastic.urn:meshtastic:node:NNNNNN will be populated.
It would be nice to see these in Freeboard, but I'm not sure what would be needed for that apart from having a navigation.position entry.
So, what are the requirements? Do I need to put them into vessels.? Do they need some particular paths populated?...
convert gps data to nmea2000 (signalk-to-nmea2000)
I'm trying to convert GPS data in 0183 format coming from my peplink router onto my nmea2000 network for further usage. But the GPS location isnt relayed to the nmea2000 bus.
I have a rbpi with canhat connected to nmea with data connection via canboat.
Receiving nmea2000 data works fine.
And data connection via tcp for receiving the 0183 gps data fine....
Connect Skanbat (shenzen topband)
I have a Norwegian variant of a topband battery with Bluetooth BMS. It’s delivered by Skanbatt. Trying to add the battery as a unit with bt-sensors, and it is not working. Wouldn’t expect that it would work without any work or configuration. But is it possible to get the required info using an iOS device? I am on summer holidays so limited tools…
Derived Data True Wind Angle
In the derived data plugin, why does TWA require navigation.headingTrue?
TWA should be relative to the bow, like AWA, and can be calculated from apparent wind and STW....
