Connecting to hidden WLAN

I have a setup with one esp8266 as WLAN Access Point ('server') and another esp8266 as WLAN station ('client').

The connection by the client is setup successfully with SSID and password and the client application can send datagrams to the server which are echoed by the server and the client receives the echoes successfully. All fine, I'm happy (so far!).

Among others I have configured the AP explicitly with: network.config(hidden = False). But when I change this to network.config(hidden = True) and keep everything else the same the client reports that it cannot connect to the server (changing it back to False makes it working rufus again!).

I noticed that network.scan() does not show any hidden network (1.9.3 and 1.9.4), while I have several in my neighborhood.

Questions: What would be the use of being able to create a hidden Access Point without being able to connect to it? Am I trying to accomplish something impossible? Am I doing something wrong (if so what)?
