cordova-plugin-fastrde-mqtt

This is a fork from cordova-plugin-fastrde-mqtt (https://github.com/fastrde/cordova-plugin-fastrde-mqtt with some fix from IOCare), a good plugin for MQTT known working for both IOS and Android. I fix some dependency to make it works again and update Documentation

Successfully testing

Now working smoothly on both IOS and Android. Tested on Jan 2021, Cordova 9. XCode 12.3

Installation Android

cordova plugin add https://github.com/linhtranvu/cordova-plugin-fastrde-mqtt.git

Installation IOS

Fresh Install

First, you need to run install command directly on IOS

cordova plugin add https://github.com/linhtranvu/cordova-plugin-fastrde-mqtt.git

Install from package.json (mean you install on Android, and copy app to MacOS) will cause missing dependency.

Add and remove IOS Platform

Sometime, we need to add, remove IOS platform and add again. In this case, you need to uninstall this package first

cordova plugin remove cordova-plugin-fastrde-mqtt

Now you can safely remove IOS platform and add again, then reinstall plugin as fresh

Sorry for this buggy installation thing, but at least we have a working MQTT plugin
