KC868A-4 RF433MHz decoding.

[franco.demei@gmail.com]

i have tested with these code is work well. RF 433M receiver pin : GPIO19




make sure you have installed "RC Switch" library.

if also can't work, maybe need change another 433M receiver for a testing.

this code work well:

Code:

/*
  Simple example for receiving
 
  https://github.com/sui77/rc-switch/
*/

#include <RCSwitch.h>

RCSwitch mySwitch = RCSwitch();

void setup() {
  Serial.begin(9600);
  mySwitch.enableReceive(digitalPinToInterrupt(19));
  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();
  }
}

The Code You Used is the same to the code I'm using. I tested the code with 2 different receivers . With same waveform output, who I posted previously. For this reason I say that is the KC868-A4 get a problem, does not read the IO19
