Nodemcu and bluetooth module, and relay

Hello, can I insert Bluetooth code here? Thanks

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

char auth[] = "xxxxx";
char ssid[] = "xxxxx";
char pass[] = "xxxx";

void setup()
  // Debug console

  Blynk.begin(auth, ssid, pass);

void loop()
