Telstra Arduino MKR NB 1500 Examples

Note: The below examples use straight AT commands so doesnt need the Arduino MKR library which can be found here Arduino MKRNB

These sketches demonstrate how to;

• Register an MKR NB 1500 on Cumulocity
• Send measurements from an MKR NB 1500 to Cumulocity

Prerequisites

1. A Telstra Arduino MKR NB 1500 board.
2. A Telstra SIM card with an active subscription.
3. A Cumulocity account.
4. A user with permissions to register devices.
5. (Optional) A DHT11 temperature and humidity sensor.
6. (Optional) The SimpleDHT library.

How to run

Register the MKR NB 1500

Open register_device. Enter your Cumulocity tenancy and user information on lines 20 - 22.

// Cumulocity tenancy config
String username = "";
String password = "";
String tenancy = "";

On line 23, give your device a name (eg MyArduino).

String deviceName = "";

Upload and run the sketch. Once successfully registered, the serial monitor will continuously print the deviceId; note this down.

Send measurements to Cumulocity

Open send_measurements. Enter your Cumulocity tenancy, user information, and deviceId on lines 30 - 33.

// Cumulocity tenancy config
String username = "";
String password = "";
String tenancy = "";
String deviceId = "";

Connect your DHT to GND, 5V, and pin 11.

Upload and run the sketch. You will now see measurements in Cumulocity.
