MQTT on port 443 with ALPN TLS and AWS

Hello,

It is now possible with AWS to make MQTT via port 443.

Here is the AWS briefing note:
Clients wishing to connect using MQTT with X.509 Client Certificate authentication on port 443 must implement the Application Layer Protocol Negotiation (ALPN) TLS extension and pass x-amzn-mqtt-ca as the ProtocolName in the ProtocolNameList.

Does the FLEXY 205 support “ALPN TLS”?

The Flexy does not currently support the ALPN TLS extension.

Currently only TLS 1, 1.1 and 1.2 are accepted.

@hms_support,

Do you plan to develop this extension in the near future ?

I have escalated your question to our development team.
I will respond back as soon as I get more information.

@CFrancoeur

The response I got from the team is the following:
“Unfortunately this is not supported, and not on the roadmap.”
