Sorry for my speling in English, I speek french.

I have a code that works perfectly on Arduino IDE.
I'm presently using Embrio ver. 2.0.8.0
I get the error : Error uploadind to Arduino:

Here the native code for IDE :

#include <SoftwareSerial.h>
#include <Nextion.h>

SoftwareSerial nextion(2, 3);// Nextion TX to pin 2 and RX to pin 3 of Arduino

Nextion myNextion(nextion, 9600); //create a Nextion object named myNextion using the nextion serial port @ 9600bps

void setup() {
Serial.begin(9600);
myNextion.init();

}

void loop() {
String message = myNextion.listen(); //check for message
if(message != ""){ // if a message is received...
Serial.println(message); //...print it out
}
}

Here is my code in the Custom Node :

Thank you!

I guess with this new version these files need to be included in the controller properties.

I'll try this.
