  2. After the Install, please read the datasheet from the installation folder:
    f.e. C:\Users\<USERNAME>\IIoT Libraries SL\<version>\DataSheets\en\Google Cloud IoT Core Client SL_en.pdf

    This datasheet gives an overview of the steps required to get started.
    For more detail on how to use Google's Google Cloud IoT Core tools, you need to follow Step 3.

  3. Read the Google Cloud IoT Core documentation [link].
  4. Run the example from
    e.g. C:\Users\<USERNAME>\Google Cloud IoT Core Client SL\<version>\Google Cloud IoT Core Client SL Example.project

  5. With the MQTT sample application, you must enter all the info (see picture, green boxes) from your Google Cloud account:
