 But if we get multiple UDP connections from one client (also different client-processes), only the most recent one is stored in the CIPSTATUS-list, even though they have different reply ports.

 Here I opened 4 instances of the application "SocketTest v 3.0.0" on my notebook, and opened 2 TCP connections, and sent 2 UDP packets (broadcasts). But we can only see 3 active connections here.
+===== Notes =====
+When we close the server with
+  AT+CIPSERVER=0
+, then the module has to be resetted!
+As far as I know, we cannot find out, on which port the server was opened.
+We can find the own IP address with
+  AT+CIFSR
+. Note, that there is no questionmark!
