Hi Noam!
I recently finished an application with almost the same setup: mbedTLS
(successor of PolarSSL with better licensing options) via socket API
(found some example for my MCU which I used as started) and SNTP client
from contrib tree which uses RAW API. Works very well since month.
Just a side node: TLS/SSL uses a default content length of 16k which is
acquired twice for tx and rx from the memory pool. For may system (with
64kb RAM) this is a lot so I had to reduced it. Luckily we're in control
of the server so we could incorporate the changes there too.
