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:204No 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:204No 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 extension 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 here.
Querying IoT Devices on IoT Hub
Hi All, today I deployed 3 IoT Hubs (SKU S3) in region "West Europe" and I got the same issue for all IoT Hubs, when I select IoT Devices, I get an error message that querying devices failed: There

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
