I’m working on multiplayer game on w7.

I use UdpAnySourceMulticastChannel class from RockPaperScissor example http://msdn.microsoft.com/en-us/library/ff431744%28v=vs.92%29.aspx

The problem appears when I want to play device-to-device which simply don’t even want talk to each other (Send working, SendTo not) – in fact, this occurs also on sample.

devices: LG E900 & HTC Trophy

//—-
Edit (after KooKiz anserw – sorry, I should wrote it at the start):
Specify a bit:
Both devices are connected to same router and see messages send to multicast group (game lobby working)

Sample application also aren’t working (see each other – game lobby working)

both applications working device-emulator

    UDP multicast usually doesn’t work over internet. It works with the emulator because they are using the local network. It should also work if you connect every device to the same wifi router.

    More information: UDP Multicast over the internet?

    If you want the devices to communicate outside of the local network, you’ll have to put a server in-between to forward the data to each device.
