In the first part of our series, we will connect a Qt app to the Microsoft Azure IoT Hub, use the Device Twin and show you how to authorize your IoT device to the cloud.
In the third part of our series, we show how Protobuf messages from the IoT Hub can be processed in Azure Functions.
The open62541 OPC UA stack with its Pub-Sub extension now supports MQTT over TLS as well as MQTT-brokers requiring a login (contributed by basysKom). This allows the direct communication between open62541 and the Azure IoT Hub and therefore highly simplifies the connection of OPC UA based IoT Devices to the cloud.
The Device Provisioning Service is a managed service running in the Azure cloud which supports automatic provisioning of IoT devices for IoT Hub.
The following sections will give a short introduction to the most important features of the Device Provisioning Service.
