  1. sas token expires

    I'm using the mosquitto library to connect my device directly to azure iot via MQTT protocol.
    For the connection, the SAS token is used.
    (Actually, I'm not using the Azure sdk..)

    My device publishes some data at regular intervals to azure iot,
    (topic : devices/mydevice1/messages/events/)
    but the device continues publishing to azure iot even after the expiration of the token.

    I found a similar problem in the stackoverflow.
    https://stackoverflow.com/questions/42345527/azure-iot-hub-sas-token-doesnt-expire
    I'm wondering if it's really a bug reported.

      • Allow for fall-through routing rules

        It would be useful to allow routing rules to be set up with a fall through processing behavior. This would allow routing logic to be structured such that duplicate property checks across a series of rules would not be repeated.

        • IoT BACnet Stack SDK for Azure

          It would be wise to add an IoT SDK with BACnet communication support. This would generally solve the common problems of using different open source libraries. Instead if Microsoft can provide this library/SDK as part of IoT SDK would be really useful for Industrial automation users.

          SDK should easily be able to provide a configurable interface to easily communicate to BACnet/IP devices available in Azure Cloud. This also should provide secure bi-directional communication options as well.

          • Create custome IoT solution

            I am new to the Azure IoT Suite and trying to wrap my head around how the system works as a whole. For my application, the IoT Hub is very advantageous for its message handling and scaling capabilities. I am wondering if I can use the IoT Hub and DocumentDB to gather and aggregate all my messages. I would then like to have an application outside the IoT Suite access the database and display to my own custome front-end.

            Can I only have the data ingestion be handled by the IoT suite? And then be able to write my own…

              • Read from IoT Hub like a generic MQTT server

                I appears that you cannot read from IoT Hub without using one of the prescribed SDKs. Furthermore it seems like reading is not well supported outside of the .NET SDK (I am talking about monitoring messages, not reading back ACKs after writing).

                I would be a lot easier if IoT Hub could be connected to with a generic MQTT connector.

                • Show SAS token in IoT Hub properties

                  It would make life easier if SAS tokens were automatically generated and presented in the portal (both under Device Explorer and Shared Access Policies). Just need user to enter a TTL value.

                    • Custom endpoints for Service Bus topic and subscription

                      Hi,

                      On portal, could you please add the "subscription" parameter to the Service Bus topic endpoints ? It will be really useful when we deal with the IoT Hub routes. Topics subscriptions are currently only available by code. This will simplify Bus uses if this is available.

                      Regards

                      • Add support for SAM3X8E Cortex-M3 to the C device SDK

                        There is Arduino Due build on SAM3X8E Cortex-M3 which is very similar to Mega 2560 from the number of pins perspective.
                        Is is possible to bring the support of this SDK to this platform?

                        • Make SharedAccessSignatureBuilder public in Csharp service client

                          It's already public in Microsoft.Azure.Devices, but we don't really want to reference this library from a client, because it mostly contains service stuff.

                          • Robust file upload (with resume) for the C device SDK

                            Azure supports uploading large files in chunks to support continuing broken uploads. This should be added in the C device SDK as well.
                            I could also imagine having the user implement this and just providing a hook to doing something with a CloudBlockBlob:
                            public Task UploadBlobAsync(string blobName, Func<CloudBlockBlob, Task> upload);

                            • Support virtual folders for Blob upload in the C device client SDK

                              Upload to blob fails when destination file name includes a virtual folder e.g. "testfolder/hello_world.txt". The sample application iothub_client_sample_upload_to_blob works as expected with a single file name "hello_world.txt", but fails with a folder prefix "testfolder/hello_world.txt".

                                      • 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.

                                        • Add ESP32 as a first class citizen

                                          ESP32 is the new and upcoming version of the ESP8266. It's cheap and more powerful than the EPS8266 and as an IoT developer I want access to it and the power of the Azure IoT suite.
