 First up, the configuration for the M4 Proxy Server, which are the parameters that handles communication with the M4 core that extends the Arduino layer. The `m4_proxy_port` is configured to `5001`, as it is the port used by clients to send the data to the M4.

 These 2 parameters are required to establish a connection with The Things Network. The `APP_EUI` and `APP_KEY` are required to be configured, as they are provided from The Things Network for example or from the LoRaWAN platform that you may try extablishing connection to. Additionally, the `DEV_EUI` will be predefined as the device will request and apply the EUI. However, if it requires to use different `DEV_EUI`, you can make the change in this section.

 Following tasks are the main processes that will be used to handle MQTT protocol. This will be able to decode incoming packets from the subscribed device and buffer the data if timeout has occurred while waiting on the MQTT packet. This will help to receive sensor data from any external device, for example using Arduino MKR WiFi 1010 with a sensor attached, using MQTT protocol.
