IOS Lan server list issue

[anthonyk]

Hi !

We have some issues testing the sample scenes on ios devices :
- We start tne demo menu on an Android tablet, a PC, a iPhone 5C ios7 and an iPad 4 ios7.
- We create a local server on all 4 devices.
- PC and Android saw there 2 servers. But ios devices didn't shown any servers even theirs. No list was displayed.
- If I enter the local address of the iphone or ipad on the PC i'm able to connect and play. and vice versa.
 
We are using a local wifi network only, no 3G.
I displayed all logs of TNET on screen but found no errors.
I used RemoteBrain to debug the scene remotly as well.
XCode gave no errors neither.
I displayed the TNLobbyClient.knownServers.list.size on Update(),  but it's stayed at 0.

So the only thing not working on ios seems to be the server discovery feature ?

Have you experienced this ? What could be wrong with ios ?

Thank you for your help !

LAN server discovery in the example is done using UDP broadcasts or multicasts. I vaguely remember something about UDP broadcasts not working on iOS a while back... or was it multicasts? TNet has an option to switch between them -- UdpProtocol.useMulticasting. Try turning it off before using UDP.

Thank you,
UdpProtocol.useMulticasting = false;  seems to be a solution for ios.
With this configuration I now have a PC that doesn't find other servers. This computer only find servers when Multicasting is true for it and other devices.
This is quite weird.
But I will stay with broadcasting if it's working with ios devices at least.

Is there any other way I could try ? Tcp instead of udp ?

Thank you again

TCP will work perfectly if you have a central "meeting server", like I do with both Starlink and Windward.
