Bluetooth auto scanner for AndroidIn this article, we will talk about the Bluetooth auto scanner for Android, which is working on the ELM327 chip. We will talk about is advantages, functionality and apps that it is able to work with.



All modern cars have the self-diagnostic system that informs the driver about the state of the vehicle and says if any block started to work incorrectly. Admit that it is very convenient: you will not have to spend a lot of money for the diagnostics on the service station.

If your car is not equipped with this useful functionality, this problem can be easily resolved by purchasing the Bluetooth auto diagnostic instrument for Android that is working on the ELM327 chip.

If you have such a device, you can connect almost any new car to the tablet or phone and perform a diagnostics “in the field”. In addition, you will be able to use your phone/tablet as a portable on-board computer, because you will be able to receive information about the fuel consumption, engine load, power, speed and condition of the fuel system.

Choosing the program

Next, we will tell about a couple of good applications that are used for vehicle diagnostics via Bluetooth for Android.


This app is the most functional. Its functionality can replace the on-board computer.

The functionality of the application:

  1. Saving your travel routes with sensor readings and fuel consumption.
  2. Testing the actuating devices.
  3. Reading and erasing errors from the electronic control unit of the car.

This program is easy to master, even for people that are far away from technology.



This app is less popular, but yet very good. Its functionality is slightly smaller than the previous one has, but it successfully performs the basic functions:

  1. Displaying the readings of all parameters of the sensor.
  2. Diagnosing and removing errors from the electronic control unit.
