Possible bug in canbus.js?

[miggat]

Hello, I'm not sure if this is the correct place to post the issue, but i'm facing this error when starting SignalK:

Mar 07 13:02:16 Trace at new CanbusStream (/usr/lib/node_modules/signalk-server/node_modules/@canboat/canboatjs/lib/canbus.js:57:12) at CanbusStream (/usr/lib/node_modules/signalk-server/node_modules/@canboat/canboatjs/lib/canbus.js:46:12) at Object.nmea2000input [as NMEA2000] (/usr/lib/node_modules/signalk-server/node_modules/@signalk/streams/simple.js:259:30) at new Simple (/usr/lib/node_modules/signalk-server/node_modules/@signalk/streams/simple.js:92:34) at createPipeElement (/usr/lib/node_modules/signalk-server/lib/pipedproviders.js:103:16) at /usr/lib/node_modules/signalk-server/lib/pipedproviders.js:72:30 at Array.reduce () at createPipedProvider (/usr/lib/node_modules/signalk-server/lib/pipedproviders.js:70:55) at /usr/lib/node_modules/signalk-server/lib/pipedproviders.js:110:37 at Array.reduce () at Object.startProviders [as start] (/usr/lib/node_modules/signalk-server/lib/pipedproviders.js:107:62) at Server.

After this error, there's no N2K input or output.

Also, I'm not sure if this is a problem with this library, the plugin itself, or signalk

The log message that you included is not an error, but output from some extra logging that I accidentally included in the latest. It should not affect the way things work in any way.

Does your connection report status in the Dashboard? Anything else noteworthy further down in the server log?

[miggat]

In the dashboard, the connection appears completely idle. No deltas at all.

I'm not sure if it's worth mentioning, but this are the firsts lines after a server restart:

Also, I tried reinstalling SignalK (after making a proper backup) and test without any other plugin installed. The result is the same.

I think is worth mentioning that as explained in this openmarine thread, wiring issues are discarded: https://forum.openmarine.net/showthread.php?tid=5226&pid=29085#pid29085

I noticed all this in the logs, but the n2k devices dont receive anything

[sbender9]

Can you please trying the following:

sudo npm install -g @canboat/canboatjs

candumpjs can0

Do you get anything?

If you want to take canboatjs out of the picture, try candump can0 . (You make need to install can-utils: sudo apt install can-utils

[miggat]

I will try tomorrow and report back. If is of any help, I already tried the candump that comes with openplotter and it shows there's traffic, but reinstalling canboatjs seems like a good option I didn't thought about.

[sbender9]

That install won't effect Signal K, but trying candumpjs may give us some insight into the issue...

[miggat]

I tried installing and running candumpjs and this is the result, which seems totally fine :S

This makes me even more lost :S

On SignalK's dashboard, there's still no activity on can0 connection, but on the MacArthur HAT I can see the can leds blinking properly.

[miggat]

I tried disabling ALL other SignalK plugins except for signalk-to-nmea200, and now I can see this error:

I also found this error: Mar 10 12:17:15 (node:5040) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 delta listeners added to [FullSignalK]. Use emitter.setMaxListeners() to increase limit (Usenode --trace-warnings ...to show where the warning was created)

[tkurki]

What is your Node version? node -v

[miggat]

My node versión is 20.11.1 Maybe i should downgrade to v18?

[tkurki]

No need for downgrade, I am barking up the wrong tree, the "not found" error is unrelated. That is probably triggered by a device on your network that is trying to make an access request.

[miggat]

It does not seem theres any missing request pending.

[miggat]

Is this connection setting correct?

[miggat]

I don't think is related, but also found this error in SignalK's server log: Mar 11 12:07:12 (node:5275) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 delta listeners added to [FullSignalK]. Use emitter.setMaxListeners() to increase limit (Usenode --trace-warnings ...to show where the warning was created)

[miggat]

I really appreaciate your time helping me and I'm sorry for the time lost. After all it seems the problem is related to the NMEA2000 network wiring. Nothing to do with SignalK or the plugin.
