I am having a problem with File Upload device sample

Viraj Kamat 40

Hello , I have followed the instructions as mentioned in Microsoft documentation for uploading a file. https://learn.microsoft.com/en-us/samples/azure-samples/iot-central-file-upload-device/iotc-file-upload-device/
The sample program is also working and sending telemetry data to the device instance on IoT Central. On pressing RUN the datafile.json file is also getting uploaded to the storage account. I can see the new files in a container in the Azure Storage Account container. In the Device file storage section in IoT Central I have added configured the cloud storage and mention all necessary details. It is showing "Your cloud storage is properly configured" message and I have enabled access.
Despite all this in the Files section it is showing 'No files found'. Can someone tell me the way forward?

Viraj Kamat Greetings!

Despite all this in the Files section it is showing 'No files found'. Can someone tell me the way forward?

Can you double check and confirm if the file is uploaded to the correct container in the Azure Storage Account with same name?

Also, To enable users to view and manage uploaded files inside IoT Central, set Enable access to On.

If not enabled, set Enable access to On.

See Manage users and roles in your IoT Central application > Managing devices for more details.

Let me know if that solves your issue or have any further queries.

Hello Ashok, I am having another issue. I am unable to see the data in widgets form on any of the dashboard pages. Even the data explorer page is showing no historical data. There has been quite a lot of data incoming on the dashboard for the last week. Until two days ago, I was able to see all historic data, and able to plot graphs on the data explorer page, but since yesterday, it is saying no data. Raw data is visible for all devices. Please help in this issue also.

Regarding first issue, I'm still waiting for an update from the team.

Could you share the region in which your resource is deployed?

Are you seeing any details related to this issue on Azure Service Health page?

Viraj Kamat Thanks for waiting so long on this issue.
After reviewing the issue, I was able to reproduce the same and found that you are using different name than your deviceid for the container folder name.

The files must be uploaded to a folder with the same name as the device ID. This is by design.

Since the IoT Device SDK uploads the files for each device into their own folder and the files view within IoT Central is per device.

If you are following the doc, and files should uploaded by the device SDK under the device id folder in the Storage account.

I would suggest, you please check below and let me know if you have any further queries.

My DeviceID is ashoktestdevice4 as shown below.

In your case, make sure you are using the correct names. I see two different names configured there while providing storage account details.

I have followed the same and able to see the files.

Storage Account:

Configuration of the Device File Storage:

Final Result:

Do let me know if that helps or have any other queries.

FileUploadSample code :

File Upload is working, and telemetry data can be seen.

Filename Suffix:

The filename - newtest has been suffixed to datafile.

File Upload Command:

File Upload Run command has been implemented. This creates a folder in the container with name same as the device Id.

VSCode Terminal:

The VSCode terminal reflects the file upload action successful.
