Hi Everyone,
My app need use WIFI Direct feature, so I refer to a Microsoft sample Code (WiFiDirectLegacyAPDemo).
For some reason, I can't use legacy mode of WIFI Direct, so I need call customer pair when got a connection request, but it always get a DevicePairingResultStatus_Failed.
This is code: https://1drv.ms/u/s!AvrPdsDWcn8akMEN-iBLhtILwLF-RA?e=g4mRHJ
Use this test app, you start a WIFI direct access point in one notebook, and connect it in another notebook:
Best Regards

The code link you provided couldn't be opened due to our policy. Could you please provide a minimum code via GitHub to help us reproduce the issue?

Below is my code how to call customer pair. The official sample code has no customer pair feature. I will put to GitHub latter.
