azure-iot-hub

In our scenario, we have a bunch of devices that communicate locally with a gateway. The gateway is responsible to aggregate events from the devices and send it to the cloud. It should also receive device configuration changes from the the cloud and transport it to the specific device. Based on my reading I would think that this is actually a typical IoT Hub scenario. And we would very much like to use the device management, messaging and maybe even twins that IoT Hub provides. However, the way the devices communicate is already implemented and shall not be changed. That means the devices

I am working on a IoT solution that will save weather data. I have googled for some days now on how to set up the backend. I am going to use Azure IoT Hub for handling communication, but the next step is the problem. I want to store the telemetry to a database. This is where I get confused. Some examples says that I should use Azure BLOB storage or Azure Table storage or Azure SQL. After some years of data collection I want to start creating reports of the data. So the storage needs to be good at working with big data. Next problem I am stuck on is the worker that will receive the D2C and

if I send a message (Cloud 2 Device) via the IoT-Hub: var serviceMessage= new Message(Encoding.ASCII.GetBytes("Hello Device")); serviceMessage.Ack = DeliveryAcknowledgement.Full; commandMessage.MessageId = Guid.NewGuid().ToString(); await serviceClient.SendAsync("myDeviceID", serviceMessage); //Send message here And try to receive the acknoledgement from the client: bool feedbackReceived = false; while(!feedbackReceived){ FeedbackReceiver<FeedbackBatch> feedbackReceiver = serviceClient.GetFeedbackReceiver(); var feedbackBatch = await feedbackReceiver.ReceiveAsync(TimeSpan.FromSeconds(1)); if

I'm trying to solve for having thousands of IoT devices deployed, all logging events to Azure IoT hub, then being able to read events created by a single deviceid only. I have been playing with EventProcessorHost to get something like this working, but so far I can only see a way to read all messages from all devices. Its not a feasible solution to read all the messages and filter client side as there may be millions of messages. The major purpose of the Azure IoT Hub is an ingestion of mass events from the devices to the cloud stream pipeline for their analyzing in the real-time manner. The

I have been reading the documentation of this new SaaS offering, but I do not see any mention about being able to send a message to the device, eg: to switch ON/OFF an equipment . https://docs.microsoft.com/en-us/azure/iot-central/tutorial-add-device I do see there is a provision to change the settings of the device, by being able to alter device-twin. Also, I read there is a way to send an "echo" to the device. But, these don't serve my exact purpose. So, is there a way I can send a C2D message, using the connection-string, which can be built using the routine-? https://docs.microsoft.com/en
