Hello,
When we use DeviceInformationCustomPairing::PairAsync() to pair with phone, the interface sometimes returns DevicePairingResultStatus::Failed. We assume this is an unknown failure. But if we ignore this error and try WiFiDirectDevice::FromIdAsync() to get WiFiDirectDevice, it will success and the P2P is actually setup successfully(e.g. ping is OK).
Can you explain the behavior above? can we ignore DevicePairingResultStatus::Failed or take it as success?
Thanks

Can the problem be reproduced by replacing the development equipment (or connected equipment)?

Actually it is easy to reproduce on our PC / phone. Per my observation, if we take the error as success, most likely WiFiDirectDevice::FromIdAsync() will success also.
BTW, I am wondering the stability of WiFiDirect on Win10. To me, it is not so stable, how about you? any advice from from to improve the stability?

Recently we worked on WiFiDirect via WinRT API, we met a few stability issues. One example is: sometimes WiFiDirectDevice::FromIdAsync() returns success, but sometimes returns NULL. Can you provide advises for us to root cause such issues?
Thanks

2020-07-01T03:25:41.28+00:00 Hello, our engineer tested this problem. The device used is an Android phone, and
DevicePairingKindsisConfirmOnly, which performed normally in the test. Can you provide some information, such asDevicePairingKindsused when connecting, and your device type, pairing error may be caused by the device does not support the correspondingDevicePairingKinds.
