ESP32 Compile error (with SoftwareSerial)

Solved
1

Hi friends. when I compile sketch for ESP32 get error . where is wrong ?

Arduino: 1.8.5 (Windows 10), Board: "ESP32 Dev Module, Default, QIO, 80MHz, 4MB (32Mb), 921600, None"

C:\Users\ERFAN\Documents\Arduino\sketch_apr08a\sketch_apr08a.ino:1:28: fatal error: SoftwareSerial.h: No such file or directory

compilation terminated.

exit status 1
Error compiling for board ESP32 Dev Module.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

the sketch is:

#include <SoftwareSerial.h>
#include <TinyGPS++.h>
#define BLYNK_PRINT Serial
#include <WiFi.h>
#include <WiFiClient.h>
#include <BlynkSimpleEsp32.h>
#include <SimpleTimer.h>


static const int RXPin = 15, TXPin = 18;

      if (gps.encode(ss.read()))
        displayInfo();

}

void loop()

Aside from asking this NON BLYNK related question here and not on Google… well, an ESP32 has like three available “hardware” serial ports and is not built to work with the basic SoftwareSerial library anyhow… Remember GOOGLE :stuck_out_tongue_winking_eye:
