 ### How to use it
 - Instantiate the class with `ConnectionManager *ArduinoIoTPreferredConnection = new WiFiConnectionManager(SECRET_SSID, SECRET_PASS);` if you are using a WiFi board, otherwise replace **WiFi** with **GSM** or any future implementation.

-- The `setDebugMessageLevel(int _debugLevel)` method is used to set a level of granularity in information output. Every debug message comes with a level which goes from 0 to 4.

The lowest level has a higher importance and is usually used for errors, which are always printed. Passing -1 as a parameter will disable logging entirely, **errors will also be ignored**.

 ### ArduinoIoTCloud
 
 - The `begin(ConnectionManager *connection = ArduinoIoTPreferredConnection, String brokerAddress = "mqtts-sa.iot.arduino.cc")` method is used to initialize a connection to the Arduino IoT Cloud through MQTT. Accepts an instance of `ConnectionManager` and returns 0 in case of failure or 1 if object is successfully instantiated.
 
 - `begin(Client& net, String brokerAddress = "mqtts-sa.iot.arduino.cc")` if connection is managed manually and not via a `ConnectionManager` a reference to a `Client` object can be used.

 - The `update()` method can be called periodically in the loop of the `.ino` file. If a `ConnectionManager` is implemented it checks network connnections. It also makes sure that a connection with the MQTT broker is active and tries to reconnect otherwise. During `update()` data from the Cloud is retrieved and changed values are posted to the proper MQTT topic.
