CCS/CC3220SF-LAUNCHXL: cc3220SF

Part Number: CC3220SF-LAUNCHXL

Tool/software: Code Composer Studio

Hi, I'm trying to establish MQTT connection with port number 443 using ALPN, however TI board CC3220SF-LaunchXL doesn't support this feature by default, so please help me with procedure of enabling it.

  • We do support ALPN but it is at the socket layer via the SL_SO_SECURE_ALPN option when calling sl_SetSockOpt. Check the programmer's guide section 7.5.5 for details on ALPN if you are curious. I don't think there is an option to include MQTT application protocol in the TLS handshake.
