Solved Multicast Sender and Receiver Example
-
Hello everyone,
I am trying MulticastSender and MulticastReceiver example from Qt's examples list. If I execute both sample applications on same machine, they work. But, If I execute any one application (For example - "Sender") on a machine and execute an another application (For example - "Receiver") on an other machine, Receiver application is unable to receive datagram packets.
Please help me out.

Hi
Make sure that windows
firewall do not block the port used.
Make sure you can ping the machines.
It sounds like such issue. :) -
Hope both systems are in same subnet.

Super. Did you also allow the port ?

Also your router might filter multicast packets.

Thanks for ur suggestion.
I also allowed the port.Well, I solved the problem. I just changed the value of Group Address. Now I am using "239.255.255.250" address as Group Address.
This is "Simple Service Discovery Protocol" Address.Thanks to everyone ... :)
