W5100 TTL value

#1

Do I understand it properly that I am not able to get information about TTL from IP header in any IP modes (IPRAW/UDP/TCP)?

Hi~ Eugeny

You can confirm the TTL information using Sn_TTL register.

So Sn_TTL register has TTL information from the last received IP packet? I talk about accessing TTL info for the packets being received, not sent. For example, to achieve task of tracing the route or assessing the distance to specific netowkring device.
