How to use the No-Blocking function for standard PID (such as OBD standard)?

[wcjxixi]

I want to get the OBD standard of the vehicle, but I want to use the No-Blocking function.

My code:

void getOBDStandard() {
  char OBDStandard[20];
  myELM327.sendCommand_Blocking("0128");    // Service 01 / PID 28
  if (myELM327.nb_rx_state == ELM_SUCCESS) {
    myELM327.get_response();
    for (byte i = 0; i < myELM327.PAYLOAD_LEN; i++) {
      OBDStandard[i] = myELM327.payload[i];
    }
  Serial.println("OBD Standard is: " + String(OBDStandard));
  } else if (myELM327.nb_rx_state != ELM_GETTING_MSG) {
  Serial.println("OBD Standard is: " + "Unavailable");
  }
}

The code above gives me the original response packet.

Which function in the ELMduino library should I use to parse the response packet? In this way, I can get the values representing the OBD standard (such as 1, 2...etc.).

I am a newbie. Please give me some tips, or better yet, add and modify the corresponding code in my code, thank you very much!
