Question

Hi,

I was using azure c sdk version 1.11.0 on my esp32 board, with that connection to iot hub using DPS service x509 certificates works fine. Blob storage is also configured with iot hub. File upload also works fine.

Recently I have updated the azure c sdk to 1.14.0 LTS_8_2024, with that Connection to hub and sending Telemetry data works perfectly fine, but file upload has stopped working.

attaching the error log from iot hub. Can you please help here.

Hello @Singh, Vineet Prakash (ext),

welcome to this moderated Azure community forum.

The SDKs are marked as feature complete so no functional changes are made anymore. Only fixes and security patches (like library updates) are done.

I also recommend to check the official Azure IoT SDK for C from Github.

Please check if these blob samples work for you:
