Start application for auto provisioning by holding switch 1 while the device start. Then follow the instructions on the LCD. This will involve connecting to the AP created by the device, searching for the SSID you want to connect to, and then entering the passkey for that WiFi network. This is currently configured for WPA/WPA2 PSK networks only.

Restart the program without holding the switch. Now the device will connect to the MQTT broker specified in the code and subscribed to the specified topic (M2MIO_DOMAIN/M2MIO_DEVICE_TYPE/M2MIO_SUBSCRIBE_TOPIC). The payload of received messages are displayed to the LCD.
