NMEA-450 support

[Henrik Andresen]

Hi,

Is KPLEX still being developed ?

I will suggest support for NMEA-450 :)

Now I use signalk and a plugin to translate to NMEA-450, but it could be nice to do it in KPLEX. Both ways :)

This is the plugin I use now

Very best from

Yes.  It's been a long time since there was a "release" although there have been plenty of updates to the develop branch in GitHub since the last one.  A nightmare job has distracted me from development work over the past year but the project definitely isn't dead. What you're talking about is IEC-61162 ("IEC 61121" per the GitHub project name is something to do with measuring the performance of tumble driers from my quick google search :-) which is another closed protocol which I've always been interested in but never seen any implementation details of.  As a pay-to-play protocol I wouldn't be able to implement it in open source code if I bought it.  The only options would be reverse engineering (and I don't have access to anything which uses it) or cribbing off someone else's code.  The plugin you reference above does have some code I could I could reference for this but I'd like to do a little research to see how representative of the standard this might be.

In short..yes! I'd be very interested in implementing this.  But (a) let me see if I can talk to the developer of the plugin you're using and (b) see "nightmare job" above + "domestic commitments" so my open source development output is not very fast currently

I've had a brief exchange with Martijn de Munnik the author of the SK plugin who has also pointed me at his Go implementation of the same thing.  Yes I'll be happy to have a crack at this but see above regarding limitations on my spare time at the moment (ie it may take a while for me to find some coding time)

Hi,

Very nice, looking forward to this in the future long time ahead :)

Will you also consider NMEA-450 input :D 

And for the output end I have some sugetions.

I'm working @furuno and using NMEA-183/2000/450 on daily basis.

NMEA-450 uses different SFID to identify who is sending messages, and also if you want to sent messages to dedicated receiver. We can talk about this later on when you have spare time to play with it, but it could be nice to have this implemented as well :D
