Canboatjs does send out heartbeat messages

tobi42OP•2mo ago

one heartbeat every millisecond? seems a bit excessive... and after the server restart the messages have stopped

once a minute

device.heartbeatInterval = setInterval(() => {
        sendHeartbeat(device)
      }, 60 * 1000)

device.heartbeatInterval = setInterval(() => {
        sendHeartbeat(device)
      }, 60 * 1000)

i have a theory... the can0 interface was in a hung-up state (no messages coming in or out), my marinetraffic app complained about no AIS messages coming in, so i sshed into the pi and restarted can0 (ifdown && ifup usually works) okay, no.. even if the messages were kept in a queue and then fired off all at once when can0 came back up, it should've been like 80 messages (one per minute the interface was down) and not a thousand per second it gets weirder... now i get the heartbeat messages in spurts of about two dozen every two seconds is it possible that something calls the canboatjs heartbeat function more than once a minute? @Scott Bender any ideas?

I don’t think anyone else could be calling it Let me take a look at the code… I don't see how canbiatjs could be doing it You can turn on debug for canboatjs:candevice you'll see a message everytime caboatjs sends heartbeat out/ I am sitting here watching it go out exactly once a minute on my boat
