SOLVED - Nano RP2040 Connect: does not send UDP packet

Official Hardware Nano Family Nano RP2040 Connect

First: the WiFiUdpSendReceiveString example works fine.

2nd: my old ESP32-arduino-stuff (converted to Nano Connect) refused to send a UDP packet.

the reason was here:

Attention: the calls of WiFi.config() are diffrent (unfortunatly).

WiFiNINA ->  WiFi.config(ip, dns, gateway, subnet); 
ESP32    ->  WiFi.config(ip, gateway, subnet, dns);
