Receiving data from BT ELM327

Hardware
1

This question follows a previous question where I was asking about how to communicate with an ELM327 through a HC-05 from a Photon 2. Thanks to @ScruffR 's help I got to the point where I could make the two devices to communicate. However, I am not getting the response I was hoping for.

Below is the code I am using:

#include "Particle.h"

SYSTEM_MODE(AUTOMATIC);

int EnPin  = D2;
String ReturnValue = "";

void setup() {
    Serial.begin(9600);
    Serial1.begin(38400);
    delay(1000);
    
    Serial.println("Initializing...");
    
    pinMode(EnPin, OUTPUT);
    digitalWrite(EnPin, HIGH);
    delay(100);

    getSetAtCommand("AT+RESET");
    getSetAtCommand("AT");
    getSetAtCommand("AT+CMODE=0");
    getSetAtCommand("AT+ROLE=1");
    getSetAtCommand("AT+BIND=1CA1,35,698DC5");
    getSetAtCommand("AT+PAIR=1CA1,35,698DC5,15");
    
    getSetAtCommand("AT+LINK=1CA1,35,698DC5");
    delay(500);
    getSetAtCommand("AT+STATE?");
    delay(1000);
    
    digitalWrite(EnPin, LOW);
    delay(500);
    getSetAtCommand("AT+RESET");
    delay(500);

    // change baud rate //
    Serial.println("Changing baud rate...");
    Serial1.end();
    delay(1000);
    Serial1.begin(9600);    
    delay(2000);
    //////////////////////

    Serial.println("Initializing ELM327...");
    
    SendELM327Command("ATZ",   2000);
    SendELM327Command("ATE0",  2000);  // Echo Off

    Serial.println("ELM327 initialized.");
  }

void loop() {
  SendELM327Command("010C", 2000);
}

void getSetAtCommand(String command) {
  Serial.print(command + ": ");
  String added_command = command + "\r\n";
  Serial1.print(added_command);
  delay(1500);
  while (Serial1.available()) {
    Serial.write(Serial1.read());
  }
}
  
void SendELM327Command(String command, int iDelay){
    String Response = "";
    Serial.print(command + ": ");
    Serial1.println(command);
    delay(iDelay);
    while (Serial1.available()) {
        Serial.write(Serial1.read());
    }
    Serial.println("");
}

The response I am getting is: 010C7F 10 79.

It is supposed to show the RPM but I am not sure what that means. According to the examples I found (for other platforms) I was supposed to receive something along the lines of:

41 0C 1A F8

Besides, turning on the engine does not seem to have any effect on the response received. Is there anything obvious that I am doing wrong or maybe I am use the wrong approach?
