cordova-plugin-fastrde-mqtt's Issues

Does this have Background Service Notifications support?

It would be great to get MQTT notifications in the background. Does this support that?

userName and password on comment on iOS

Hi, on src/ion/*.m the lines for userName and password are on comment.
Indeed, the label "userName" of the options has to be changed to "username" twice on the same line.
With these changes, all is working fine

offlineCaching: false - getting error on publish

With offlineCaching: false configuration I unable to publish message. Getting error:
direct publishing failed: at file:///android_asset/www/plugins/cordova-plugin-fastrde-mqtt/www/mqtt.js:215

Example code:

mqtt.init({
                        offlineCaching: false,
                        host: cfg.host,
                        port: cfg.port,
                        username: cfg.username,
                        password: cfg.password,
                        ssl: cfg.ssl
                    });

                    mqtt.on('connect', function() {
                        mqtt.subscribe({
                            topic: '/aircon/state', qos: 0
                        });
                        mqtt.publish({
                            topic: '/aircon', message: 'state'
                        });
                    });

                    mqtt.connect();

How stable is this plugin?

How stable is this plugin?
How does it compare to other similar plugins? For example cordova-plugin-mqtt?
This is the first plugin that seems to support SSL. Are there known bugs?
Is it safe to use in professional environment?

Why is there offlineCaching?

What does offlineCaching do and what is the advantage of using it?

need help to fix MQTT ios cordova plugin [CONNACK problem]

Hi guys!

Firstly, many thanks for your submitted open source code at https://github.com/fastrde. We appreciate your work! Thanks!

We tried to use your code from Github: https://github.com/fastrde/cordova-plugin-fastrde-mqtt and got some troubles.... We found out that the fix from giriiton solved a part of problems (decencies) > https://github.com/giriiton/cordova-plugin-fastrde-mqtt/blob/master/plugin.xml#L10 but we have a problem connected with "CONNACK" - it seems that the problem began from your source code

"SyntaxError: Unexpected identifier 'CONNACK'. Expected ')' to end an argument list."

Guys, could you please help us! And double check your code (Object C binary) and fix that issue? Or maybe you can show the problem place and we'll fix that.

Had no chance to play with Object C code.... :)

How to Import?

I'm struggling to understand how to import your plugin. (I'm still learning how to use Cordova...) For now, I'm doing this:

import mqtt from '../../../plugins/cordova-plugin-fastrde-mqtt/www/mqtt.js';

This allows me to build, but I get an error when I connect:

ERROR ReferenceError: cordova is not defined
at Object._connect (mqtt.js:150)
at Object.connect (mqtt.js:137)

I'm thinking I'm doing something wrong with the import or how I'm linking to the plugin. I installed it from the command line. I did have to use --force to get past a database dependency. (I have a later version of the database code.)

Many requests of connections

In the broker of mqtt I can see many messages:

[WARNING] MQTT disconnecting duplicate client id "q-buzon-col_messages_3eee7f81ac409aa0" ("xxx:11443 -> xxx:1883")

Only for devices Android, It's like it falls into a loop of connection attempts.

The plugin has a reconnect logic?
Has anyone happened to this?

thanks in advance
