Need help with updating disconnected devices
hey, I am new to azure and IOT and I need help with knowing how to do this. The scenario is that: I have a set of Linux devices that can't be connected to the internet ever, these devices should be connected to another device (will have internet) which will act as parent to all these disconnected devices. The challenge is to update these child devices using Azure IOT, the updates will be deployed in the hub, and it has to passed to child devices via parent device and automatically needs to be installed in the child devices. The parent might not require this update or might. How will I do this? also I can't use any scripting mechanisms. Now when I surfed a bit through azure documentation, I found out that I can use device update for this, What I found was: 1) setup every device in IOT hub 2)set the device with internet as parent and others a child 3)set up MCC module in parent 4)Connect the devices physically (Lan or Wi-Fi) 5)Roll out updates Now I don't know whether this is true or not, it's just my understanding. I am having few doubts: 1)do we also add the child devices (disconnected devices in IOT hub), if yes what if we have 1000 devices? (I'm asking about scalability) 2)How do I actually physically connect the parent and child devices, do I just plug in Lan/Wi-Fi, or do I have to do anything else? 3)How to add MCC Module? 4)how does this actually works? is it feasible?
Files from IoTHub in storage are not JSON
Hello, In my IotHub, I defined entrypoint for storage. While I see that the files are arrive successfully, the type of them is not JSON and I defied. The content is JSON, but the extension is empty and not JSON as I used to have. What can i define wrong this time? ThanksProcessing ordered IoT streams in Azure
There are thousands of articles on the Internet talking about how the cloud can be used to process discrete (un-ordered) streaming IoT data. But almost all are short on specifics and the design trade-offs you need to make when processing ordered IoT streams, at scale. This article discusses why scale can be difficult to achieve, especially when the ordering of the events (aka Series events) is important. Jeff Hollan wrote an article which illustrates the challenge when using Azure Functions, for example. And if you need a primer on Real-time processing, Events, Messages, Series events and Discrete events, please review the following articles: Real time processing Events, Data Points, and Messages - Choosing the right Azure messaging service for your data Choose between Azure messaging services - Event Grid, Event Hubs, and Service BusIoT Device Simulation - Device simulator covering a wide range of Azure IoT SDK features
Hi all, In case you will find this useful for your IoT projects, you will find here an #iot device #simulation tool implementing a wide range of #azure IoT SDK capabilities. The approach of the solution is to complete other existing tools. The solution is a .NET Core application. It can be used : as a development tool as a complete IoT flow simulation tool from the device perspective (C2D/D2C, including IoTHub modules) for building simulation platforms (containerized, Docker image). Many configurations are possible through JSON-based settings. All details are here ;). Enjoy 😉
