taoqf / mqtt.js Goto Github PK

Hi @taoqf , when i try connecting to any any stream with any protocol. The connection close callback gets called regularly. Even the below snippet doesn't work. Is it a bug ?.
var mqtt = require('@taoqf/react-native-mqtt')
var client = mqtt.connect('mqtt://test.mosquitto.org')
client.addListener('connect', () => {
console.log('connected');
});
client.on('connect', function () {
client.subscribe('presence', function (err) {
if (!err) {
client.publish('presence', 'Hello mqtt')
}
})
})

last version is 4.2.8

Whenever tires to connect to a server by mqtt protocol, close event is emitted before getting connected. But works fine with ws/wss protocol.

const mqtt = require('@taoqf/react-native-mqtt')
const client = mqtt.connect('mqtt://XXX.XXX.XXX.XXX:1883);

Example: const client = mqtt.connect('mqtt://test.mosquitto.org:1883');

my enviorment: [email protected]

the dev no problem, but pakageing apk INVALID_STATE_ERR is causing the device to CRASH;

I find start mqtt. the app crash.
I try no run mqtt , the app no problem.
I don't find other problem.

You can hlep me.

Here, I have integrated this plugin in my react native project and trying to connect URL with protocol mqtt. Referred doc
https://github.com/taoqf/MQTT.js/blob/react-native/README.md
Am unable to detect either connected or not. Below is my snippet
let mUrl = "mqtt://xxxx.xxxx.in";
let mOptions = {
username: server_user, password: server_pass,
protocol: 'mqtt',
clientId: 'mqttjs_' + Math.random().toString(16).substr(2, 8),
rejectUnauthorized: false,
protocolId: 'mqtt',
defaultProtocol:"mqtt",
protocolVersion: 4,
clean:false
}
var client = mqtt.connect(mUrl,mOptions);
client.on('connect', function () {
console.log("connected");
})
})
client.on('error', function ( err) {
console.log("client err : " + err)
})

Can anyone help ?

Thanks

@taoqf I can't connect to mqtt broker with tls( Also I've seen that you removed 'tls' file in 24d8c0f. Can you propose or help to find solution with it?

Hey! I'm trying to connect and get the data from topic sent by sensor. Unfortunately the connection not working.
Any help is appreciated.

import init from 'react_native_mqtt'
import AsyncStorage from '@react-native-async-storage/async-storage'

 init({
  size: 10000,
  storageBackend: AsyncStorage,
  defaultExpires: 1000 * 3600 * 24,
  enableCache: true,
  reconnect: true,
  sync : {
  }
});

const host = '52.11.11.11'
const port = '8883'
const connectUrl = `mqtt://${host}:${port}`
clientID = "clientID-" + parseInt(Math.random() * 100);
export default class TestScreen extends Component {

  constructor(){
    super();
    this.onConnectionLost = this.onConnectionLost.bind(this)
    this.onConnect = this.onConnect.bind(this)
    const client = new Paho.MQTT.Client(host, Number(port), clientID);
    client.onConnectionLost = this.onConnectionLost;
    client.connect({ 
      onSuccess: this.onConnect,
      useSSL: true,
      userName: 'admin',
      password: 'admin',
      onFailure: (e) => {console.log("here is the error" , e); }

    });

    this.state = {
      message: [''],
      client,
      messageToSend:'',
      isConnected: false,
    };
  }
  onConnect = () => {
   // const { client } = this.state;
    console.log("Connected!!!!");
    //client.subscribe('hello/world');
    this.setState({isConnected: true, error: ''})
  };

It log :
here is the error Object {
"errorCode": 7,
"errorMessage": "AMQJS0007E Socket error:undefined.",
"invocationContext": undefined,
}

Is it possible for you to add more info about the linking process on the readme as well as with kind of data the message type supports ?? Thank you very much
