Software Serial Read showing wrong data

Projects Programming
1

I'm using a Nextion display to generate tokens on serial. Different buttons on the display generate a corresponding token.
When I wire the display through an FTDI, the serial data is as expected.
But when I read the display data on SoftwareSerial through the arduino and print it to serial monitor, its not the same data anymore.

So for example, if Button A is generating "1" on toggling, while the display is wired directly through an FTDI, serial monitor shows "1", but through softwareSerial it shows "49"

I intend to use the incoming date with a switch case.

#include <SoftwareSerial.h>
SoftwareSerial nextion(10, 11);
int command;
void setup() {
  Serial.begin(9600);
  nextion.begin (9600);
}
void loop() {
  if (nextion.available()) {
    int command = nextion.read ();
    Serial.println (command);
    delay (1000);
  }
}

serial monitor shows "1", but through softwareSerial it shows "49"

What is the ASCII value for '1'? Wouldn't happen to be 49, would it? Just so happens that it IS.

Store the value read from the software serial instance in a char, instead of an int, and you'll see different results.

So I remember now the Nextion instruction set did mention that print() outputs as ASCII. Thanks a lot, Paul!
