Hi! I'm having trouble with mqtt implementation in nodejs. I'm connecting with the example nodejs script, with a clean:false setting: const mqtt = require('mqtt'); const client = mqtt.connect('mqtts://mqtt.flespi.io:8883', { clientId: 'flespi-examples-mqtt-client-nodejs', // see https://flespi.com/kb/tokens-access-keys-to-flespi-platform to read about flespi tokens username: `FlespiToken ${process.env.FlespiToken}`, protocolVersion: 5, clean: false }); if("undefined"!==typeof hljs)hljs._ha();else if("undefined"===typeof hljsLoading){hljsLoading=1;var a=document.getElementsByTagName("head")[0],e=document.createElement("link");e.type="text/css";e.rel="stylesheet";e.href="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.7.0/styles/default.min.css";a.appendChild(e);e=document.createElement("script");e.type="text/javascript";e.onload=function(){var d={},f=0;hljs._hb=function(b){b.removeAttribute("data-hljs");var c=b.innerHTML;c in d?b.innerHTML=d[c]:(7 But when I check the settings of the session, it clearly says, it's a clean session: { "result": [ { "size": 0, "ip": "37.76.123.229", "id": 2761155786, "connected": true, "cid": 2042338, "clean": true, "client_id": "flespi-examples-mqtt-client-nodejs", "expires": 0 } ] } if("undefined"!==typeof hljs)hljs._ha();else if("undefined"===typeof hljsLoading){hljsLoading=1;var a=document.getElementsByTagName("head")[0],e=document.createElement("link");e.type="text/css";e.rel="stylesheet";e.href="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.7.0/styles/default.min.css";a.appendChild(e);e=document.createElement("script");e.type="text/javascript";e.onload=function(){var d={},f=0;hljs._hb=function(b){b.removeAttribute("data-hljs");var c=b.innerHTML;c in d?b.innerHTML=d[c]:(7 I don't really see what could be the problem here...

Nodejs MQTT implementation issue

Hi!

I'm having trouble with mqtt implementation in nodejs. I'm connecting with the example nodejs script, with a clean:false setting:

const mqtt = require('mqtt');

const client = mqtt.connect('mqtts://mqtt.flespi.io:8883', {
  clientId: 'flespi-examples-mqtt-client-nodejs',
  // see https://flespi.com/kb/tokens-access-keys-to-flespi-platform to read about flespi tokens
  username: `FlespiToken ${process.env.FlespiToken}`,
  protocolVersion: 5,
  clean: false
});

But when I check the settings of the session, it clearly says, it's a clean session:

{
  "result": [
    {
      "size": 0,
      "ip": "37.76.123.229",
      "id": 2761155786,
      "connected": true,
      "cid": 2042338,
      "clean": true,
      "client_id": "flespi-examples-mqtt-client-nodejs",
      "expires": 0
    }
  ]
}

I don't really see what could be the problem here...

Hello. Try adding the parameter to the configuration:

sessionExpiryInterval: 600

Example:

const mqtt = require('mqtt');

const client = mqtt.connect('mqtts://mqtt.flespi.io:8883', {
  clientId: 'flespi-examples-mqtt-client-nodejs',
  // see https://flespi.com/kb/tokens-access-keys-to-flespi-platform to read about flespi tokens
  username: `FlespiToken ${process.env.FlespiToken}`,
  protocolVersion: 5,
  clean: false,
  properties: {
    sessionExpiryInterval: 600
  }
});

By the way, our AI assistant in the chat on flespi.io (upper right corner) handles such questions very well. ;)
