Hey Sergio... Yes, I'm aware we are 'classless' now, but the nomenclature was the easiest way to describe/ google it. I understand /23... much the same as class-B. I assume that they have a virtual gateway devoted to each drop... not sure why, but the gateway is ping-able. We are shipping the

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.
