Seatalk converted to NMEA0183 message are "slow"

[miggat]

Let me explain. All my boat came with raymarine equipment, everything using Seatalk1 network.

Before I updated to SignalK 2.7.1, those messages were working perfectly fine, updated on the data bowser every 2 seconds.

However, now those messages come only every 10 or 15 seconds. Sometimes even 30 seconds or more.

According to the converter itself: https://digitalyacht.es/producto/seatalk-nmea/ the the leds are blinking every second (which means the device is properly set to work at 38400 baud rate), but this is not reflected in SignalK data browser.

Just to rule out an issue or some kind of filtering in the data browser page, I created a flow in node red, and indeed the data is coming every 10-30 seconds.

Any idea?

So from Signal K's point of view this is just nmea0183 data over serial, right? One way to look into it is to active debug key signalk:streams:serialport in the Server Log, you should be seeing stream of nmea messages updating more or less constantly.

[tkurki]

Data Browser updates every 2 seconds, so you can't use it for monitoring true update rate, but nothing like 10-30 seconds.

I will try the debug key signalk:streams:serialport and report back, thanks.

I added the debug key and I receive a lot of events, but still neither the data browser nor node red is updated :S

There are only Writing entries there, i don’t see any input.

Do you mean that there is no longer any input from your seatalk in Signal K? Previously yousaid that it just updates at reduced rate.

Are you sure the physical connection is ok?

[miggat]

There are incoming connections, i just don't know how to capture them in the log :S

But in the data browser I can see how data is being update every now and then (ranging from 2 to 30 seconds aprox).

Also, in MacArthur HAT i can see both RX and TX activity leds blinking, although RX is not blinking nearly as fast.

[miggat]

Finally it seems the error came from the ST<->NMEA converter. I reset it and now it works fine.

However, the canbus sentences are not being read by my Axiom+ display (although canbusjs is recognized as a source). But's that's another topic.

Thanks
