Azure IoT

This forum is to get feedback on the new IoT services: Azure IoT Hub and Azure IoT suite. This forum will help the engineering team collect feedback from our customers and users and help us understand and prioritize the roadmap.

  1. IoT Hub as generic MQTT Broker

    At present, there is no easy way to send/receive direct MQTT messages between different devices. We would have to write custom code (using C2D messages or Direct Methods) for routing messages from one device to another. This would bring in additional latency in the response times. It would be great if IoT Hub can function as a generic MQTT broker where devices can publish and subscribe for messages.

  2. Provide hardening configuration for IoT Hub

    IoT hub is the entry point from devices to cloud. WE should be able to reduce the attack surface in the IoT hub by


    • Configuring the ports that will be in listening mode (Ex. 443 only)

    • Configuring the protocols used (Ex. MQTT Only)

    • Configuring the TLS protocol (Ex. TLS 1.2 only) and cipher suites

    It must be possible to configure all these during the deployment of an IoT Hub

  3. Allow changing device certificates

    Allow device certificates to be changed through the Azure Portal without deleting/recreating a device.

  4. Plans to change Azure IOT to hub free tier a paid tier

    Once your proof of concept is working on the free hub, it would be nice to scale it to a paid hub

  5. Add Windows Hello support for IoT and Connected Vehicle Platform

    This could be extended to Microsoft Connected Vehicle Platform e.g. Manufacturers could use Windows Hello as an immobiliser for keyless driving when the driver places their hands on the steering wheel.

  6. Field Gateway SDK: Please provide a Device Management module

    The Field Gateway SDK will be used to manage leaf node devices. Device Management module is a must have and at this point must be coded by each developer implementing a gateway. Please provide a baseline Device Management module that ships with the Gateway.

  7. Option to turn off system properties being put in MQTT topic name

    Currently when you send a message to a device via the IoT Hub, system properties are output in the topic name, such as:
    devices/matt/messages/devicebound/%24.mid=c7c6ee3d-9c90-4114-be93-a5c7f06740c4&%24.to=%2Fdevices%2Fmatt%2Fmessages%2FdeviceBound&iothub-ack=full&et=stmd
    Gets lot longer if you use more features like custom expiry, etc.

    For constrained MQTT devices not using the SDK (eg a 16 bit device), this eats a massive amount of bytes. It doesn't seem a great reason to have to implement a protocol gateway.

    It would be great to be able to turn system property output off on a device by device basis when registering devices.

    Still allow custom properties to be output.

  8. Add more metrics like failure count, response times, message sizes, count of c2d messages

    Add more metrics like failure count, response times, message sizes, count of c2d messages.

    It will be great if we can get these metrics without needing a storage account setup (For instance: Azure websites does not need a storage account to get metrics like number of requests, response times, http errors etc).

  9. gc object already tracked

    considering the python lib azure-iothub-device-client (1.4.6)
    tested on a Raspberry Pi 3 B+ with python 3.5.3
    the issue seems related to the "sendeventasync - callback"

  10. Documentation/Examples - Provide a reference device client with all best practices applied

    There are a lot of examples in the documentation, but they are, for the sake of simplicity, focused and tailored for showing the topic at hand.
    There are also some good practices referenced here and there with some examples, but again all scattered around.

    Please provide a full-fledged reference device client implementing all IoT Hub features on the client side, correctly implementing error handling, retry policies, disconnection and re-connection, etc.

  11. make it simpler..

    why do MS solution always have to be so hard to understand. Stop geeking and make things simple for people for once.

    I have been programming for years, playing with arduino's and raspberry pi's, using PowerShell to update JSON data to sites like thingspeak. But as usual Azure succeeds to completely obfuscate how to start simply. For the last hour I have been struggling to figure out how to simply let my arduino send data to Azure. Very frustrating. Stop trying to be the smartest kid on the block.

  12. Implement backup/restore option for DPS (Device Provisioning Service)

    DPS has a scope-id that is embedded in a device during manufacturing. As such, there can be devices on the shelve with a DPS scope-id embedded, waiting to be enrolled. This makes the scope-id critical information.

    Once a DPS instance is created, a scope-id is assigned. When DPS would be deleted at any time, there is no way to get exactly that scope-id back.

    Pls implement a backup/restore option for this.

  13. GA for Symmetric key attestation for azure IoT Hub Device Provisioning

    Hi,

    Currently support for Symmetric key attestation in device provisioning service is in preview, Any ETA for GA?

    Also I am not able to sees support for the same for C# sdk (Microsoft.Azure.Devices.Provisioning.Service and Microsoft.Azure.Devices.Provisioning.Client ) any plans to support Symmetric key attestation from c# sdk.

  14. By making it easier to understand

    Make some straightforward examples. It takes me hours to do even the simplest thing with Microsoft Azure. Even trying to understand what the Portal is going on about when wanting to do something that would take 5 mins in another technology. It is so frustrating

  15. Azure IoT Edge C2D messages

    I successfully implemented a IoT-Edge Module but i didn't find out how to receive C2D messages or call direct methods here.

    Finally i found a Note:
    Currently IoT Edge only supports send messages into one module from another module, direct C2D messages doesn't work.

    Now i'm worried...

    The used IoT-Hub (Standard tier) should support this,
    but i can't find any information about the IoT-Edge support.

    Are there any announcements, supported features lists, code samples?

  16. Azure IoT Hub management SDK for Java

    I'd like to manage Azure IoT Hub on my Java Application.
    There is C# version of IoT Hub management SDK but I can't find Java SDK.

    C# IoT management SDK: https://github.com/Azure/azure-sdk-for-net/tree/psSdkJson6/src/SDKs/IotHub

    I especially Upload CA Certificate automatically something like that.

  19. Need guidance on how to handle twin data > 8kb

    The customer anticipates needing to push larger configurations via Device Twins than the currently supported 8K limit. We need to detail the best patterns and practices to push larger configuration files to/from devices & module twins.
