Hi, yes i had the pins connected and i think i solved the problem, after 2 days of trying.
So i edited the code for arduino to look like this:
#include <SoftwareSerial.h>
void setup(){
Serial1.begin(9600);
}
void loop()
{
Serial1.write(1);
Serial1.write(2);
Serial1.write(3);
Serial1.write(4);
}
And in my many attempts to make it work i made ports 19 and 18 as software serial, but they were already hardware serial ports, and it made the program to bug.
But now i have another problem my wemos serial looks like that
-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-11234-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-11234-1-1-1
do you know how to get rid of these -1s? is there a function that only gets serial when its not empty?
