Currently, in the sample sketches for the ESP8266, in azure-sdk-for-c-arudino, there is no option for using X509 Certificates for the authentication with the Azure IoT Hub.

However, it looks like there is such option for the ESP32, thus, it will be awesome this to be added for the ESP8266 sample, too.

If-statement in the ESP32 example:

Hi @Vitomir2,

I'm also looking for a minimal working example for ESP8266 of Azure IoT Hub authentication via x509.
Did you find anything meanwhile?

Hi @david-it,

No, I have not and did a workaround by just using an auto-generated X509 certificate, in order to finish my tests for the thesis project, because I did not have much of time till the deadline. I was planning to start making this example and suggesting it as a PR, but did not find time for this.

Hi @Vitomir2, I hope you are all well.

Is there any plan to introduce this yet? I am currently only connecting via Sas token. But creating X509 certs would be preferable due to my requirements,

Thanks a lot!
