I've got a couple of UA55MU7000's, 65" and 75" TV's, all with firmware version 1144. The C4 IP drivers is trying to communicate on port 1515, but a detailed port scan doesn't list that port. I tried using AnyMote iPhone app and it immediately sees the TV's, but wants to communicate on port 8001. If I tried and connect via the app the TV immediately pops up with ALLOW or DENY popup window. So 8001 must be the correct IP port, instead of 1515?
