Read Data with Ethercard Library

Hello,
I can send a UDP-message to LINUX server with this simple script, sucessfull. But I dont find a way how to read a reply message of the server.
It seems to be that the class “ether.packetLoop(ether.packetReceive())” can work. But I dont find a working example, yet.
Has anybody a well working example?
