Need support for upload file to Blob on iOS

[LeePepe]

• OS and version used: macOS High Sierra 10.13.6 iPhone 8 Plus simulator iOS11.4 Xcode : 9.4.1 (9F2000)
• SDK version used: I use cocospod install SDK

Using AzureIoTHubClient (1.2.4) Using AzureIoTUtility (1.1.4) Using AzureIoTuAmqp (1.2.4) Using AzureIoTuMqtt (1.1.4)

Description of the issue:

I want to upload a file to Azure Iot Hub Blob. And I found the API:

IoTHubClient_LL_UploadToBlob But when I only do that, it will report a Error:

Code sample exhibiting the issue:

There is my code. data is iOS Data struct and it may be a image or a audio.

let source = UnsafePointer<UInt8>((data as NSData).bytes.assumingMemoryBound(to: UInt8.self))

if (IoTHubClient_LL_UploadToBlob(iotHubClientHandle, "iOS/\(filename)", source, data.count)) != IOTHUB_CLIENT_OK {
    print("failed to upload \(filename)")
} else {
    print("success to upload \(filename)")
}

Console log of the issue:

Hi @LeePepe ,

have you tried running just the sample in your machine, using the same connection string you have used above?

If not, please do so and let us know if it works.

Other than that, have your code ever succeeded uploading to blob, or this is the only result you ever got? What is the size of the data (data.count) you are trying to upload?

@LeePepe have you tried this again to see if this works?

Closing due to inactivity - upload to blob is supported on iOS.
