KC868A-4 RF433MHz decoding.

[franco.demei@gmail.com]

A4 RF433M receiver pin is IO13, here is code:

Code:

#include <RCSwitch.h>

RCSwitch mySwitch = RCSwitch();

void setup() {
  Serial.begin(9600);
  mySwitch.enableReceive(digitalPinToInterrupt(13));
  Serial.print("begin test");
}

void loop() {
  if (mySwitch.available()) {
   
    Serial.print("Received ");
    Serial.print( mySwitch.getReceivedValue() );
    Serial.print(" / ");
    Serial.print( mySwitch.getReceivedBitlength() );
    Serial.print("bit ");
    Serial.print("Protocol: ");
    Serial.println( mySwitch.getReceivedProtocol() );

    mySwitch.resetAvailable();
  }
}

As per ESP 32 WROOM-32E Electrical diagram ( See Attachment) the RF 433Mhz pin INput shoul be IO19, The IO13 shoul be used for Temperature sensor 1. In any case I tried the  above code , but still nothyng appen
