Enable the package (Optional)

This package implements Laravel auto-discovery feature. After you install it the package provider and facade are added automatically for laravel >= 5.5.

This step is only required if you are using laravel version <5.5

To declare the provider and/or alias explicitly, then add the service provider to your config/app.php:

'providers' => [

        Salman\Mqtt\MqttServiceProvider::class,
];

And then add the alias to your config/app.php:

'aliases' => [

       'Mqtt' => \Salman\Mqtt\Facades\Mqtt::class,
];

Configuration

Publish the configuration file

php artisan vendor:publish --provider="Salman\Mqtt\MqttServiceProvider"

Config/mqtt.php

    'host'     => env('mqtt_host','127.0.0.1'),
    'password' => env('mqtt_password',''),
    'username' => env('mqtt_username',''),
    'certfile' => env('mqtt_cert_file',''),
    'port'     => env('mqtt_port','1883'),
    'debug'    => env('mqtt_debug',false) //Optional Parameter to enable debugging set it to True
    'qos'      => env('mqtt_qos', 0), // set quality of service here
    'retain'   => env('mqtt_retain', 0) // it should be 0 or 1 Whether the message should be retained.- Retain Flag

        $output = $mqtt->ConnectAndPublish($topic, $message, $client_id);

        if ($output === true)
