Network Connection via Wifi Direct
I have followed this tutorial about making a multiplayer game using blueprint on Unreal Engine 4.12 source version(compiled):
now that I have finished my job, when I export it for android and try to connect some devices via Wifi direct, I can't connect my game to other devices!!! I know that the server of the game must be hotspot. I think I can make session successfully because the lobby map is opened(Option is listen)!... but other clients can't find server session.. this is my settings on DefaultEngine.init
also I have added these two permissions!
once my laptop (win10 64x) was as hotspot and also it was the server of the game and I could not connect my android ported game(from my tablet) to my laptop!!! (they were connected via Wifi direct) once my android device was as hotspot and other android device was as client but I could not connect clients to hotspot server as owner of session...!!! what I have to do? can I connect (my game) clients to (my game)server via wifi direct?? also I don't know what I have to see on logcat to know the reason of issue(on Monitor.exe)!!! thanks a lot..
[SOLVED] I have solved it using BluePrint.. just go to and follow [this Video tutorials]. then you must open DefaultEngine.init and set:
and add all permissions like:
I think there were some other permissions for wifi and network, you can search on android central website. then you can export you game and install it on some devices (android/windows were tested) then you can connect your game via wifi direct or by Modem(just connect some devices to a specific wifi modem and play multiplayer with your connected friends via modem). this was solved 1 year ago on UE4.12, good luck...
