@iwd: I have lost a bit track what APIs iwd is offering for WPS. Is
API like proposed below possible to implement for iwd?
Here's the iwd WPS API. It is called WSC (Since the later specs are
actually named WiFi Simple Configuration)
Note that we only support STA mode WPS, however there is no separation
of obtaining credentials and connecting. It all happens in one
transaction. So once you invoke PushButton() you should be connected
after a while and the method call will return then.
