Module identity fetch issue
I have registered an edge device[gateway] to Azure IoTHub using x509 self signed certificate. The device got registered fine and modules [edgeAgent,edgeHub] got deployed along with some custom edge modules- with deployment status 200, device and modules status reporting. The modules are running on the edge device but the modules keep restarting as they couldnt authenticate. edge Device registration is through x509 self signed certificate, with below properties in config.toml # Manual provisioning with x.509 certificates [provisioning] source = "manual" iothub_hostname = "REQUIRED_IOTHUB_HOSTNAME" device_id = "REQUIRED_DEVICE_ID_PROVISIONED_IN_IOTHUB" [provisioning.authentication] method = "x509" identity_cert = "REQUIRED_URI_OR_POINTER_TO_DEVICE_IDENTITY_CERTIFICATE" identity_pk = "REQUIRED_URI_TO_DEVICE_IDENTITY_PRIVATE_KEY" Logs from edgeHub: [INF] - Unable to authenticate client <deviceid>/<custom_edge_module> with cached service identity <deviceid>/<custom_edge_module> (Found: False).

Please let me know where could the issue be for modules not able to communicate with iotHub
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, Alex
