IoT Creators sample code for Nordic devices

A sample application that connects Nordic devices (e.g. Nordic Thingy:91) to the IoT Creators platform.

Before you start

Before you compile and install this sample application please follow a basic guide that explains how to communicate between the IoT Creators platform and your device.

https://docs.iotcreators.com/docs/nordic-thingy91

In the next steps, we assume that your device is already registered on the IoT Creators platform and you know how to decode payload sent from a device and how to send a downlink message.

Usage

In Active mode the application every 60 seconds sends to IoT Creators platform basic sensors readings.

{"Temp":21.98,"Press":1.0116,"Humid":39.99,"Gas":13086,"Vbat":4371}

Immediately after pressing the main button, the application sends this information to the IoT Creators platform.

{"Msg":"Event: Thingy:91 button pressed, 000000000000000"}

where 000000000000000 is the device IMEI number.
