In the past I enabled ALTCP layer to add TLS and I used altcp_tls_mbedtls examples present in lwip repo. I thought it was the way to add TLS to lwip.
Let's say it is "our" way to do that.
Recently I looked at some example projects of NXP, such as this[1]. This is an example of a TLS httpd server. TLS is added by mbedtls, but ALTCP lwip support is NOT enabled (and altcp_tls_mbedtls is NOT enabled too). It seems NXP uses a different (patched?) httpd implementation with integrated mbedtls support. I couldn't understand if this is a smarter way to add TLS support to lwip (that avoid ALTCP at all) or an old way that should be avoided nowadays that is available ALTCP and altcp_tls_mbedtls.
Hard to tell without being NXP, but I'd say they either just don't know ALTCP or they refuse to use it because of other reasons. In the end, both implementations work, but ALTCP saves you from doing the work yourself or over and over again for every TCP server/client.
