Can't get signalk-to-nmea2000 to transmit on native can interface

[navado]

I have a board that has two native can interfaces canC and canE. The board receiving navigational data from nmea0183 over serial. This may be re-transmitted and used in widgets without problems.

Problem description

My goal is to send nmea2k PGNs to native CAN interface and receive it with candump on another interface (interfaces connected to nmea2k backbone) Target setup: nmea0183->[signalk-server]->canC->(nmea2k backbone)->canE->[candump]

I cannot get messages on candump. I also don't have another nmea2k plotter or display here.

Backbone seems working, data seen in candump

SignalK server also receives nmea2k data from the backbone

[sudo cangen canC]->canC->(nmea2k backbone)->canE->[signalk-server] # data seen in data browser with unknown PGNs

Interfaces:

Interfaces configured either with canboat or with canboatjs in SignalK server without any difference in behavior.

The system is Debian12.5 running on imx-8m plus based industrial PC (arm64)

Appreciate help or direction

Make sure you are using "canboatjs", not "canboat"

[sbender9]

Oh. I see you tried both. Definitely won't work with canboat

To confirm the actual data being sent out, turn on debug for canboatjs:canbus (under Server > Server Log)

[navado]

Well, it looks like canboatjs was just not installed and there were no indication that it's an issue. After npm install @canboat/canboatjs the data flows.
