Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
I'm working on an iPhone application for a school project and I'm a little stuck on connecting to the phone from a PC.
What I want to do is connect to the phone from a PC and send data back and forth. I am using BSD sockets on the iPhone end and I'm looking to bind to some port and accept connections from the computer (i.e. the iPhone is the server, the PC is the client).
Over Wifi, this works fine, but once I try to do it over 3G, the connection doesn't happen.
I am binding to the IP address that corresponds to the pdp_ip0 network interface (which I am pretty certain is the 3G one). bind() succeeds, listen() succeeds, but when I try to connect from another computer, the connection is never accepted (although accept(), on the iPhone side, doesn't fail with an error). I'm wondering if this is a networking issue - is the IP from pdp_ip0 "visible" to the outside world? Do 3G networks do NAT? I hope I'm asking the right questions...
Once again, IF I connect the phone and the PC to the same WiFi network, the connection is accepted and everything carries on as expected... so I'm pretty sure it's not a programming error...
