Hi everyone , i have 2 problems:
1.) i use the Nextion Display 7" (Model:NX8048K070) with an "Arduino Uno",
if i want upload the sketch with the Nextion Editor to my Display i get a error if this line is in my code "Serial.begin(9600);"
So i have to remove this everytime for uploading but this line is important for my communication with the arduino else the functions dont work.
2.) I have to Swap the RX/TX cable everytime, so my TX ->TX , RX->RX for upload and for communication my TX->RX and RX->TX is this normal?
