TLS 1.0 and 1.1 Support on Azure Web App
I know Azure is winding up support for TLS 1.0 and 1.1 by August 2025. Does anyone can help me to access our existing IoT devices to connect to Azure Web App using this TLS 1.0 and 1.1? Our device were connecting to azure server fine until Mid March 2025. At end of March 2025 we lost access to this IoT devices which uses TLS 1.0, 1.1. Any thoughts or any one have any idea why it stopped before the deadline of August 2025? And what can be done to get back this devices online? #IoTHub #WebApp #Azure #TLS #TLS1.0 #TLS1.1 #SNI
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?
Get Device to Cloud messages in IoT Hub using Rest API
Hello, I'm currently trying to get the messages that I sent to my azure iot hub using rest api (postman), but without success, I always got 204 no content. thats how i'm sending the message: Type: POST Url: https://{{iothub-north}}/devices/{{new-device}}/messages/events?api-version={{api-version}} Authorization: SharedAccessSignature sr={my sas-key}&sig={my-sig}se={my-se}. Answer: 204 No Content. thats how i'm trying to get the messages: Type: GET Url: https://{{iothub-north}}/devices/{{new-device}}/messages/deviceBound?api-version={{api-version}} Authorization: SharedAccessSignature sr={my sas-key}&sig={my-sig}se={my-se}. Answer: 204 No Content. I was searching for some documentation and found this: https://learn.microsoft.com/en-us/rest/api/iothub/device/receive-device-bound-notification however, for what I understood, it only works for cloud to device messages, so can someone help me how can I get the messages that I sent from my device to my azure iot hub? Obs: I've created one service bus to link in my azure iot hub just to be sure that I'm receiving the messages that I sent, and it's working, so probably the issue is something about the way I'm trying to GET these messages.
Fails to publish with user-defined topic to IoT hub
Hi all, I am new to azure ecosystem. I followed some examples and documents and able to connect to the Azure IoT Hub and able to send data. The data is being sent on device/<deviceID>/messages/events topic(telemetry message) topic. From same application, I am not able to publish the message on custom topic(user-defined). Can you please help me if I am missing any additional configuration/settings for Azure IoT?Visual Studio 2019 extension for building REST APIs exposing IoT Hub features
Hi all, If you need to write REST APIs (.Net Core) to expose or complete IoT Hub APIs or create a facade, this https://marketplace.visualstudio.com/items?itemName=JonMikelInza.IoTHubDotNetCoreRESTAPITemplate will help you to save a few minutes. It creates a ready to use solution in a few seconds and allows you to focus on important code (business logic, etc). The created API includes other features like: - API versioning - Automatic OpenAPI generation (versioned according to API versions) - separated layers - minimalistic solution with required dependencies only The only thing you need to do is to set the IoT Hub connection in the configuration file (appsettings.json). More details https://marketplace.visualstudio.com/items?itemName=JonMikelInza.IoTHubDotNetCoreRESTAPITemplate.

I try to create a new IoT Device (that worked based on notification) but still the query is broken, therefore I can't read the DeviceConnectionString. Any ideas, what I can do to solve this issue? Thanks & with best regards, AlexLearn TV -Learn how to develop secure IoT solutions with Azure Sphere and IoT Hub 13th October 2020
In this session Dave and Mustafa will deploy an Azure Sphere application to monitor ambient conditions for laboratory conditions. The application will monitor the room environment conditions, connect to IoT Hub, and send telemetry data from the device to the cloud. You'll control cloud to device communications and undertake actions as needed.
Powershell for opening and running CAD files
Hello Community, I am new to Powershell and scripting language. I am trying to automate a sequence of steps that I do in my process of 3D printing which are repetitive. Can anybody guide on it? I have used the Powershell script to open a file, and run it on a MATLAB platform. The basic steps are as listed here. 1. Open the software (3D sprint or any CAD software like Solidworks) 2. Import the CAD design from a location 3. Make an array of the design (optional step) 4. Export the design in the printable format 5. Select the printing material 6. Send the design to print Since these are repetitive steps, I want to know how can I automate these? Thanks
