RE: Arduino MKR 10xx, ETH Shield and Amazon Web Services: Safe MQTT with SSL and Certificate

Dear Jan,

Thank you very much for this article.

I use the same hardware as you : Arduino Mkr Zero + Mkr Eth shield.

I would like to connect to a MQTT server that support TLS or SSL, no certificate needed but just Login / Password.

So I stuck on this part of your code : sslClient.setEccSlot(0, certificate);

With a MQTT client on computer I use theses setting :

Connectivity : Websockets

Enable user authentification: User / password

TLS/SSL Mode : Certificates and keys provided externally

Protocol : TLSv1.2

Do you know how is it possible to modify your code to connect to these kind of MQTT with TLS server ?

Thank you very much.
