We have ported Azure IoT Middleware for FreeRTOS on our device based on Microchip MCU SAM9x60. We have created Azure IoT hub and trying to establish connectivity from device to IoT Hub. We are using TI Wifi module CC3235SF for network connectivity. On this module we have Baltimore CyberTrust Root Certificate for authentication.
When device sends MQTT Connect packet to IoT Hub, we do receive connection acknowledgement in sequence as below:
Any reason why IoT Hub server is returning incorrect bytes for CONNACK packet variable header?

Hello @Chandrasekar, Madhura Community SME's on this topic or our team will review your scenario and circle back at the possible earliest time.
Hello @QuantumCache , did anyone from your team get a chance to review the scenario described above?
Hi @Chandrasekar, Madhura , apologies for the delayed update on this. We are still working on this issue internally. We will update this thread once we have more information on this. Please watch out this thread for updates sometime next week. Thank you!
Hi @QuantumCache and @LeelaRajeshSayana-MSFT , sorry for following up so incessantly , but did anyone in your team get a chance to review the issue described above. Our project is kind of stuck at that point and we would really appreciate any help.
Hello @Chandrasekar, Madhura Sorry for the delay, Last week I was OOF and Now Leela is OOF, so sorry for the inconvenience caused during this holiday season!
We have escalated this internally and the team will get back soon.
Hi @Chandrasekar, Madhura , Greetings! I apologize for the delays in addressing this issue and highly appreciate your patience. I am following up to see if you get a chance to review the below response we got from Dane. Do you have any logs available from the device that you can share with us for further investigation.
Hi @Chandrasekar, Madhura
Are you able to share more details on this scenario? Do you have any logs from the device?
We haven't seen this issue before, and I have my doubts that the IoT Hub would be incorrectly sending MQTT packets (but nothing is impossible).
Hi @Dane Walton and @LeelaRajeshSayana-MSFT .
I apologize for the late response, actually we do not have any logs from the device, so we were trying to replicate the same scenario but we are unable to do it, so from last few days we are trying an alternative approach of using of TI Wifi module CC3235SF to connect to IOT hub server directly. So for now I would mark this issue as closed, as I am unable to provide you with more details.
Thank you.
