I can't configure where the problem is in the connection between the arduino and OBDLink SX

Using Arduino Programming Questions

Hi! for my project, i'm using the OBDLink SX as my OBD2 cable and i'm connecting it to a USB-to-TTL adapter(FT232BL) so i can connect to the arduino through the TX and RX pins. for my code i'm using the ELM327 library (GitHub - PowerBroker2/ELMduino: Arduino OBD-II Bluetooth Scanner Interface Library for Car Hacking Projects). Now when i upload the code, this is what the serial monitor displays:

Attempting to connect to ELM327...

and this is the code that i'm using :

#include "ELMduino.h"
#include <SoftwareSerial.h>

// Define the pins for SoftwareSerial
#define ELM_TX_PIN 10 // Arduino pin to ELM327 Rx
#define ELM_RX_PIN 11 // Arduino pin to ELM327 Tx

SoftwareSerial elmSerial(ELM_RX_PIN, ELM_TX_PIN); // RX, TX

#define ELM_PORT elmSerial

const bool DEBUG = true;
const int TIMEOUT = 2000;
const bool HALT_ON_FAIL = false;

ELM327 myELM327;

void setup() {
  Serial.begin(115200); // Start the hardware serial for debugging
  ELM_PORT.begin(115200); // Start the SoftwareSerial for ELM327

  Serial.println("Attempting to connect to ELM327...");

  if (!myELM327.begin(ELM_PORT, DEBUG, TIMEOUT)) {
    Serial.println("Couldn't connect to OBD scanner");

    if (HALT_ON_FAIL) {
      while (1);
    }
  }

  Serial.println("Connected to ELM327");
}

void loop() {
  float coolantTemp = myELM327.engineCoolantTemp();
  float rpm = myELM327.rpm();
  float speed = myELM327.kph();

  if (myELM327.nb_rx_state == ELM_SUCCESS) {
    Serial.print("Temperature: ");
    Serial.println(coolantTemp);
    Serial.print("RPM: ");
    Serial.println(rpm);
    Serial.print("Speed: ");
    Serial.println(speed);
    
    // Send data in a single line for easy parsing
    Serial.print("DATA,");
    Serial.print(coolantTemp);
    Serial.print(",");
    Serial.print(rpm);
    Serial.print(",");
    Serial.println(speed);
  } else if (myELM327.nb_rx_state != ELM_GETTING_MSG) {
    myELM327.printError();
  }

  delay(1000); // Adjust delay as needed
}

ps i'm using digital tx and rx pins because according to what i read the "original" tx and rx pins are used for the connection to my pc and debugging. pls help i'mm really confused
