Service Fabric cluster can be started/stopped by using “Service Fabric Host Service”. Since version 5.0.217.100 Service Fabric Host Service is set on “Manual” in development cluster, which prevents automatic start of the cluster That means that sometimes you will surprisingly will not be able to...

Once the data is stored in the IotHub it can remain there for max 7 days. As long the data is in the hub it can be read by various readers. Commonly data is read by using Azure Stream Analytics. However, sometimes it is required to implement a native reader. There are two approaches when reading events...

If you want to programmatically implement device management in IoTHub, you should use a package . Microsoft.Azure.Devices. This package provides a very simple API for device management. IotHub maintains under the hub a DocumentDB, which you typically cannot see. We say, “it is transparent for developers...

When using IotHub, we can send Cloud-to-Device messages from any application to device, without of need to tune anything in the infrastructure. As long device is connected to internet, we can send (push) messages (commands) to it. Following code snippet shows how to start receiver loop and how...

To send telemetry data from device, we will use Microsoft.Azure.Devices.Client or generally one of following two packages: First one is used when programming devices on a full desktop (typically simulators). If your device is running on UWP you will use the PCL package. Before we send telemetry data...

As you might already know, AForge is a .NET library for Image Processing. A lot of people prefer using .NET wrapper for OpenCV known as EmguCV, and no doubt it has stronger image processing capabilities. However, being a wrapper, it has its own limitations and sometimes AForge proves to be a better...

For some years now, we are talking about IoT as mega trend. This is good, but not good enough. It is obvious that powerful marketing influence people to think in many different ways, which often leads to misunderstanding about what IoT really stands for. So I decided for me to setup this year on...

When invoking Receive method on deice side, you might get following error: {"Http Protocol does not support a non-zero receive timeout\r\nParameter name: timeout"} This is typically caused by explicitly specifying timeout parameter. Because implementation of HttpTransport does not support timeout...

Sometimes some device (IBM Think Pad or even Surface PRO 4) might get some issues with USB drivers. In that case your board is not recognized in Arduino IDE and you cannot select COM port, where the board is connected. If that happen, please first reboot your machine. Note that reboot is not always required...

This year on Azure on Tour in Frankfurt we organized an IoTLab for all interested attendees. We scheduled 3slots of 2 hours. Unfortunately they all ware booked out in very short time. We prepared for this IoT lab a weather station on Arduino as described here . If you follow provided...

Azure IoT Hubs supports Amqp protocol as default fast transport. But there are few interesting variations, which are not well documented or not obvious. For example, when implementing the device code you can specify explicitly the protocol, which should be used. As you see on the next picture, TransportType...

IoTHub uses in general (with some iot specific improvements) messaging technology behind Azure Service Bus. That means that connection strings of IoTHub are same or similar as in a case of service bus. For example, if you open up azure management portal, you can grab the connection string: However these...
