-===== Übersicht =====
-  * Single MicroPython-Modul **Esp32UdpClient.py** zum Empfangen von UDP-Daten
-  * Single MicroPython-Modul **Esp32UdpServer.py** zum Senden von UDP-Daten
-===== Benutzung =====
-  * Datenaustausch zwischen UdpClient und UdpServer
-  * UdpClient(Esp32) wartet (nicht blocking!) auf Daten vom UdpServer(Pc)
-  * UdpClient(Pc) wartet (nicht blocking!) auf Daten vom UdpServer(Esp32)
