Re: Device experiences with Azure IoT Central
Hi Dalibor, sorry for the late answer ont his one If the question is still of order, I recommend you check out the device catalog. All the ones that are PnP certified should work with IoT Central seamlessly. I did a quick search for GPS in the catalog and several devices came back: https://devicecatalog.azure.com/devices?certificationBadgeTypes=PnP&searchTerm=GPSRe: Cloud Property vs. Device Property
I think a good way of differentiating is by considering the following: - Cloud properties are only visible on the Cloud side (these are never sent to the device) - Device properties are accessible on both sides (Cloud and device) Transferring data between device and Cloud costs, so you should always consider how you can reduce that data transfer when and where possible. If a device doesn't need to know about information about itself (like the room or floor or building it is in), then you can use Cloud properties for these, while if the device needs that information for operating, you will want to use device properties.Re: Regarding digital twin
Hi sarthak, Have you followed the instructions from this doc? https://docs.microsoft.com/azure/digital-twins/how-to-ingest-iot-hub-data If data is not flowing from your hub to your instance of ADT through an Azure Function, then you might want to check the logs of the function to see if anything went wrong thereRe: Is Raspberry PI Bullseye also supported by Defender for IoT agent installation?
Hi Sander van de Velde , The Defender for IoT micro-agent currently supports the following Linux Operating Systems (OS): Note: Yocto support will be delivered in the next release. The micro-agent can be deployed as a binary package, or as a source code that can be incorporated as part of the firmware. The customer can modify, and customize the agent as needed. RPi Bullseye is not officially supported, and the team has prioritized other platforms support for now. Requests to support any specific OS/Distro can be sent to defender_micro_agent@microsoft.comRe: Vision AI Dev Kit integration with UWP application
The Vision AI Devkit can stream video over RTSP protocol which can be used on a local network (simple router with DHCP server and no Internet connection). See https://azure.github.io/Vision-AI-DevKit-Pages/docs/RTSP_stream/. Another option is to use the HDMI out which will display the camera with bounding boxes. If you want to use this video out in a Windows app, you can consider using a USB video capture card (that converts HDMI to USB) and use the video stream in your Windows app as if it were a regular USB cameraRe: Integrating external webserver to IoT Central
IoT Central will allow you to export data to other apps/services or to be itself integrated into a broader application leveraging its APIs. But we'd need to know what your external web server is doing to better guide you. What's the scenario, what it is that you want your web server to keep doing and what type of integration would you need with IoT Central?Re: Question about integrating Azure IoT Hub support middleware into FreeRTOS
Hi Ido I confirm this is the official samples code, but the actual middleware is sitting in another repository. You can find more about the middleware along with links to resources in this blog post: https://techcommunity.microsoft.com/t5/internet-of-things-blog/expanding-azure-support-for-constrained-devices-azure-iot/ba-p/2782396Re: Does Azure Iot support dynamic sensor assignment?
Hi Andrew Azure IoT Hub does not have a notion of "object" and "sensor". Each "thing" (we call it "device") connecting to the service has a unique identity and will send telemetry, synchronize its state and receive commands through that connection. But Azure IoT Hub is just one element of a solution and all the data and meta data from devices can be sent to a time series service like Azure Data Explorer where you can work on the data, or (and it seems this might be an even better fit for you) to Azure Digital Twins where you can create models for your data and use the graph to query that data. Azure Digital Twins allows you to describe the relationship between twins and using the graph you can create, update and delete these relationships. Learn more about this here: https://docs.microsoft.com/en-us/azure/digital-twins/how-to-manage-graphRe: Questions about VAIDK, Shutter Options & External Trigger
Technically speaking you can do this, but The Azure Percept DK doesn't have a list of supported camera nor documentation specifically to do this as it is a dev kit designed to experience and evaluate the Azure Percept Vision camera. That said Azure Percept is using Azure IoT Edge and IoT Hub which you can work with directly, modifying modules configuration and setup and even code to use a different camera. I believe the Vision module (the one running the vision module) uses the RTSP feed from the camera, so it shouldn't be too hard to modify it. Also you can take a look a the VisionOnEdge project which makes building such projects simpler (and which can be used with the Azure Percept DK): https://techcommunity.microsoft.com/t5/internet-of-things-blog/bringing-your-vision-ai-project-at-the-edge-to-production-is-now/ba-p/2259359Re: Ewon Flexy to Azure IoT central
It'd be great if you could share how you connected your Flexy to IoT Central considering the Ewon samples only show how to use a connection string without using DPS. IoT Central requires a ScopeID to connect a device to it. Once the connection is established, you need to setup your script so that the Flexy uses the expected MQTT topics and abides with Device Twins, Direct Methods and telemetry conventions defined by IoT Plug and Play. This sample shows how to code in C to achieve this: https://docs.microsoft.com/en-us/azure/iot-develop/tutorial-use-mqtt, and I guess you could leverage the sample to configure the Flexy so you can run commands from IoT Central.Re: Questions about VAIDK, Shutter Options & External Trigger
Hi Mouman, AFAIK, the VisionAI Dev Kit doesn't have sensors like motion detector for what you are trying to achieve. I recommend you take a look at Azure Percept which proposes a newer devkit which you could more easily customize to achieve your goal.
