Sample nRF9160: Azure IoT Hub

I created an Azure IOT Hub and simulated a X.509 device using C and device SDK for Azure.
No problems here.
Then I run sample nRF9160: Azure Iot Hub and receive the following error
Now I look for some guidance to troubleshot the mqtt_connect error.
 
First:
Can Nordic please clarify the certificate requirements mentioned on page Azure IoT Hub — nRF Connect SDK 1.3.99 documentation in more detail.
Does Baltimore CyperTrust Root certificate equate to file RootCA.pem?
Does Device certificate equate to file mydevice-public.pem?
Does Private key equate to file mydevice-private.pem?
Files under the ..\azure-iot-sdk-c\tools\CACertificates directory listed here:
Second:
How does one  best  investigates mqtt_connect errors ?

  • Hi Martin,

    thank you for looking into this. I did as you suggested I uncommented CONFIG_AZURE_IOT_HUB_LOG_LEVEL_DBG=y in proj.conf and I followed all the steps to provision the certificate more than once. I still receive the same error. I attached the latest log file. What else can I do to troubleshoot?

  • Here is another thought. Could you please have a look at my Kconfig file. Maybe I am doing something wrong there?

  • Hi Apfelsine,
    Still looks like there some issues with the certificates unfortunately.

    You can find the Baltimore CyberTrust Root certificate by following the link in the instructions here.

    The Server-certificate is this.

    The RootCA.pem that you mention is probably the generated certificate, that should be uploaded to the IoT Hub.

    "Does Private key equate to file mydevice-private.pem?" - Yes
    "Does Device certificate equate to file mydevice-public.pem?" - I think this needs to be chained with the intermediate-certificate.e.g.

    -----BEGIN CERTIFICATE-----
    <Device cert>
    -----END CERTIFICATE-----
    -----BEGIN CERTIFICATE-----
    <Intermediate cert>
    -----END CERTIFICATE-----
