Ich benutze arduino UNO und mega2560. Ich verwendete 2 Module NRF24L01. ist eine für das Senden und andere empfangen. Problem: Ich bekomme zufällige Werte auf Empfängerseite von Arduino seriellen Monitor. Wenn ich Int-Typ verwende, gibt es zufällige Ganzzahlen kontinuierlich. Wenn ich String-Typ verwende, gebe ich zufällige Zeichen.NRF24L01 + PA + LNA (Transceiver) kommuniziert nicht zwischen zwei arduinos
