Moin,
hab nen Problem mit meinem Nextion Display.

Das ist mein Testcode. Die Variablen werden an das Display übersendet, aber die 2 Buttons funktionieren nicht, und ich bekomme das Klassische "recvRetCommandFinished err".
Das Display ist am Arduino Mega an Pin 28 und 29 via SoftwareSerial verbunden.
Mit Serial1 und 2 funktioniert es genau so wie mit SoftSerial.
Kann mir jemand helfen?
