I'm building something that needs to connect to a Pi3 wirelessly but there won't always be a wifi network for them to talk over. So I was hoping to use wifi direct to get them to talk directly.

So far i've been having problems finding a library that will run on both Windows 10 and Raspbian. I looked at this question about connecting Android and Pi3 but he's using Arch Linux on his Pi (which I will install if there is no Raspbian alternative). That question is also based around Android for the connecting device, I'm unsure how to actually get Windows to search for a Wifi Direct network and then to connect to it since Android appears to just connect without much extra setup.

Ideally What I need is a library that will work on Windows and Linux that can be used in C++ or C# for handling all the Wifi Direct stuff...

I have been recently researching on my project just similar with yours. I'll give my solution below.

  1. first of all, you shall have WiFi module that support WiFi-Direct used by desktop linux/windows.

  2. in case rpi3 <--> desktop linux, you can connect them via wpa_supplicant with p2p commands.

  3. in case rpi3 <--> desktop windows, I recommand windows 10 because it's the only verison that support WiFi-direct and provide API via UWP.

  • shame that windows makes you use UWP though there is probably a hacky way around it – user3797758 Dec 8 at 13:46
