Finally after a long wait I received the order for OBD2 Bluetooth scanner. It looks quite bulky as I thought but it quite fits perfectly into my cars OBD port.
Once successfully connected to OBD port I paired my phone with the OBD scanner using Bluetooth connection. I installed a couple of most popular OBD2 scanner apps for Android and the output which I found was far more amazing. I could really communicate with my car and read the data from car ECU.
