Hello @Fischer, Johannes
There is a limitation for editing files in Azure portal. You can edit a file which size is under 2.1MB

Hallo,
i am using the free IoT Hub with a messagerouting to a container in a blob storage. In general it works very well. But when the file size of the avro-file exeeds 2.1MB i get an error message. You can see it in the attachment. This is something i wonder about, because the chunk size window ranges from 10 to 500MB.
Does this relate to the free tier of the IoT Hub? Do i need to have an other tier to increase the chunk size?
Best regards
jo

So, no there is no limitation to the IoT Hub, it's just a limitation of the Azure portal.
I'm not sure what you mean with chunk size. This is normally related to the D2C messages. This is the limitation of 8000, 400.000 etc. messages per day. One D2C message is measured in chunks with the size of 0.5 Kb or 4 Kb (the larger one if the IoT Hub is not running on a free tier). So, eg. a message of 6.1Kb is counted as 2 chunks (in case of a S1 size it hub) or 13 chuncks for the free tier.
Sending over a file to Azure storage using IoT Hub is only metered regarding a start and end message .
