NOTE
|
MQTT protocol is only implemented in base 28 and above FW and Configurators. This guide will not work with earlier versions of FW and CONFIGURATOR. |
Setup your Azure account
Refer to the online Azure documentation. Follow the steps outlined in the sections below to create your IoT hub and get started:
NOTE – The examples in this document are intended only for dev environments. All devices in your production fleet must have credentials with privileges that authorize only intended actions on specific resources. The specific permission policies can vary for your use case. Identify the permission policies that best meet your business and security requirements.
Create Resources in Azure IoT
Refer to the online Microsoft Azure documentation. Follow the steps outlined in these sections to provision resources for your device:

Azure IoT hub Creation
When logged in the Azure console, Press 
and select – create new resource.
Figure 1. Create new resource
Select Internet of things in the Categories on the left.
Figure 2. Accessing Things
Press Create near the 
icon.
Basics tab
1. In the Basics tab choose your subscription. Create a new Resource group. Enter IoT hub name (Can be any created name). Select Region that is closest to you (North Europe for Lithuania). 2. Choose the wanted Tier, Free tier should be used for testing purpose, alternatively use standard. (You can find all the necessary information about tiers when you click Comapare tiers below option box). 3. Then choose your Daily message limit according to your needs (8000 for Free plan) (You can find all the necessary information about Daily message limit when you click See all options below option box). 4. Press: Review + create
Figure 3. Selecting IoT
Check if all the parameters are as you intended and click Create.

Add device to IoT hub
Press , Home and click on your created IoT Hub.
Figure 5. Selecting IoT hub
Copy hostname and press devices In the left menu.

If you see a warning: |
Go to: Migrate to DigiCert Global G2 at the bottom of this tutorial. |
Figure 6. Hostname and devices
Select Add Device in Devices tab.
Figure 7. Add Device
Once you are inside Create a device tab: 1. Enter your device IMEI in the device ID field. 2. Other fields here should be left default 3. Authentication type: Symmetric key Connection this device to an Iot Hub: Enabled 4. Press save.
Figure 8. Creating a device
To get your primary and secondary keys go to Shared access policies, change Connect using shared access policies to Allow and click on iothubowner.
Figure 9. Device data endpoint
An iothubowner tab will pop out on the right (These files will be used in configuration).
Copy: 1.Primary key 2.Secondary key 3.“iothubowner”

Configuration
In the GPRS tab, under Server Settings select:
1.Domain – Hostname (copy here the host name from your Iot Hub overview window in Azure) 2.Port: 8883 3.Protocol – MQTT 4.TLS Encryption – TLS/DTLS
In the GPRS tab, under MQTT Settings select:
1.MQTT Client type – Azure IoT 2.Device ID: IMEI 3.Primary SAS key – Primary key from ‘iothubowner’ shared access policy 4.Secondary SAS key – Secondary key from ‘iothubowner’ shared access policy 5.SAS Policy Name – iothubowner
Figure 11. Device configuration
Certificate creation and upload
Download DigiCert Global Root G2 certificate and put it inside a new folder: Download DER/CRT
Converting certificate to .pem format
Follow the tutorial to convert certificate here
|
Please note: Configurator only accepts PEM FILE format. You can use any method to convert .crt file to .pem format. |
Upload certificate to device
Upload the file you have created to the device using configurator > Security > Certificate > upload
Data sending
Trigger a high priority event so that device would start to send data to the server. In the device configurator screen check for the Status > GSM Info > Records Sent records count.
Figure 12. Sent records count
On the Azure service > IOT hub > Overview there is a Device to cloud chart that will show the records received.
