Hi VerenaSchmidt11, I have noticed that you have made changes to introduce username and password fileds in MQTT connect structure. To conenct to Azure IoT Hub, we would require device certificate and private key in addition to the Root CA cert(Baltimore cert). Have you modifeid the MbedTLS_TlsAdapter to incorporate these changes as well? One more thing could be that the MQTT version is not updated. Could you also ensure that the version has been changed from 3 to 4. Hope you had refered the post related to Azure conenction already, where the user was able to successfully conenct to Azure IoT Hub. Kindly take a look into the changes in the patch file atatched in that post for reference. Hope it helps and please reach out us if you still face any issues. Thanks. BR, ShanamthiP     ...
