Disconnect after connect using WPS

[Pascal K]

Thanks for pointing that out.

I meanwhile discovered that the connection didn't work as expected because
I was using a Sony Xperia ZL Android 4.3 as a client.
With every other device I now tested it does work as I expected.

Anyway thanks for your time.

Pascal
