The altcp functions are mapped to mbedTLS in the files under 
"src\apps\altcp_tls\". You just need to enable them and link them in.

mqtt initialization works much like normal, but you have to assign a 
"tls_config" in struct mqtt_connect_client_info_t:
mqtt_client_info.tls_config = altcp_tls_create_config_client(cert, 
sizeof(cert));

where "cert" is a certificate readable by "mbedtls_x509_crt_parse()" 
(e.g. x509).
