SoftwareSerial ESP32

Hello community,
I am using 2 ESP32 for testing a One Wire software Serial:
1x az-delivery-devkit-v4 (sends data)
1x esp32-poe-iso (receives data)

The connection is GPIO5 to GPIO5. I check the pin signal by an oscilloscope,
but the receiving board cant read the data.
The sending board sends every 50ms a Byte (0xFA).

PXL_20210411_095716510

What i do wrong?
In SerialMonitor i can only read “NoData”, that means no byte reveices

Code for sending:
#include <Arduino.h>
#include “SoftwareSerial.h”

volatile bool execute;    // Trigger
hw_timer_t * timer = NULL;
portMUX_TYPE timerMux = portMUX_INITIALIZER_UNLOCKED;

// Code with critica section
void IRAM_ATTR onTime() {
   portENTER_CRITICAL_ISR(&timerMux);
   execute = true;
   portEXIT_CRITICAL_ISR(&timerMux);
}

SoftwareSerial swSer1;
void setup()
{
  // Configure the Prescaler at 80 the quarter of the ESP32 is cadence at 80Mhz
  // 80000000 / 80 = 1000000 tics / seconde
    timer = timerBegin(0, 80, true);                
    timerAttachInterrupt(timer, &onTime, true);  

  // Fire Interrupt every 1s (1 million ticks)
    timerAlarmWrite(timer, 50000, true);      
    timerAlarmEnable(timer);

  swSer1.begin(4800,SWSERIAL_8E1,-1,5);
}

void loop()
{
  if(execute){
    char inByte = 0xFA;
    swSer1.write(inByte);
    portENTER_CRITICAL(&timerMux);
    execute = false;
    portEXIT_CRITICAL(&timerMux);
  }
}

Code for reveiving:

#include <Arduino.h>
#include "SoftwareSerial.h"

SoftwareSerial swSer1;
bool NoData;
char inByte;

void setup() {
  // put your setup code here, to run once:
  swSer1.begin(4800,SWSERIAL_8E1,5,-1);
  Serial.begin(112500);
   while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only
  }
}

void loop() {
  swSer1.listen();
  //Serial.println("Data from port one:");
  // while there is data coming in, read it
  // and send to the hardware serial port:
  while (swSer1.available() > 0) {
    inByte = swSer1.read();
    Serial.write(inByte);
    NoData = false;
  }

  if(!NoData){
    if(inByte == 0){
      Serial.println("NoData");
      NoData = true;
    }
  }
}
