I've got a problem with my soft ap solution. When i connect a client to the ap the connection gets established and everything works fine. But I've noticed that when i set a ping to the host, it looses connection every 2 minutes and then suddenly regains connection. This unfortunatly is unnacceptable for my solution.
I found this link: On using the WiFi Direct Api on Windows? , which describes the same problem, but the answer isn't clear enough and i would like a code example or a more elaborate explanation.
In my solution, I use this class: https://learn.microsoft.com/en-us/uwp/api/windows.devices.wifidirect.wifidirectadvertisementpublisher?view=winrt-19041 with legacy settings set to "enabled": https://learn.microsoft.com/en-us/uwp/api/windows.devices.wifidirect.wifidirectlegacysettings.isenabled?view=winrt-19041
I have encountered exactly the same problem because I removed the following line from MS sample :
var wiFiDirectDevice = await WiFiDirectDevice.FromIdAsync(deviceInfo.Id);It seems that if you don t create the wifiDirectDevice object, Windows will automatically disconnect the client two minutes later (although in the meantime you have been able to exchange some data). What helped me was to compare my code with the following sample : https://github.com/gerfen/WiFiDirectLegacyAPCSharp/blob/master/WiFiDirectHotspotManager.cs#L128
Note that I also encountered another problem when I added this line because an exception is triggered depending on the client device configuration ( see the following topic : Wi-Fi Direct UWP timeouts (Exception from HRESULT: 0x800705B4))
