Control 433mhz switch with Adafruit Huzzah ESP8266 and Transmittor

Hi there, I recently started sniffing around with Blynk and wanted to turn a 433Switch On and Off with the help of an Adafruit Huzzah ESP8266 and a 433MHZ transmittor. I succeed with an Arduino Uno but not with an ESP. When I execute my coding, my ESP keeps hanging and shows strange characters. Could you possibly help me?

My Code:

#define BLYNK_PRINT Serial


#include <SPI.h>
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <NewRemoteTransmitter.h>

NewRemoteTransmitter transmitter(12345678, 10, 268);
char auth[] = "XXX";

char ssid[] = "XXXX";
char pass[] = "XXXX";
BLYNK_WRITE(V1)
{
  int pinValue = param.asInt();
  Serial.print("Lamp staat: ");
  
if (pinValue < 1){
  Serial.println("Uit");
  transmitter. sendUnit(1, false);
  
}        

else {
  Serial.println("Aan");
  transmitter. sendUnit(1, true);
  }

}
void setup()
{
  Serial.begin(9600);

  Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,150), 8442);
}

void loop()
{
  Blynk.run();
}

Dig out rcswitch which works with ESP’s.
