You can use OBD (Onboard Diagnostic) tools to find out whether the subsystems of your car are running as they should or not without going to a mechanic. From identifying the fuel economy of the car to diagnosing the check engine light, you can perform many functions using ODB tools.

What Is an OBD2 Adapter?

An OBD2 adapter is a small device that connects to your car. It works as a bridge between the ECU (Electronic Control Unit) of the car and the special application running on an external device like a computer or mobile phone.

Now the Bluetooth technology has made it even easier as an OBD Bluetooth Adapter allows you to use your smartphone or tablet as a scanning tool. Moreover, the interface of the applications running on your personal devices will also be the same that will collect data from the OBD Bluetooth Adapter connected to your car.

There are multiple types of OBD2 adapters but the ones equipped with Bluetooth technology are much more convenient as compared to the traditional ones. When it comes to OBD2 Bluetooth adapters, there are basically two different types as listed below.

OBD2 Bluetooth adapter with App

Most OBD2 Bluetooth adapters can work with numerous third-party apps built for both Android and iOS. However, some OBD2 Bluetooth adapters can only work with specific apps developed by their respective manufacturers. They might still work with a third-party app but in order to get the best and most reliable results, you’ll need to use a purpose-built app for these OBD2 Bluetooth adapters.

Multi-OS Adapters

Some OBD2 Bluetooth adapters can pair and work with multiple types of operating systems. Not only do they offer the same results across all the platforms but they also improve flexibility. Most people now own smartphones running on either iOS or Android and the OBD2 Bluetooth adapters with multi-OS support really come in handy. However, such Bluetooth OBD2 adapters are usually expensive.

That’s why we have compiled a list of the most important factors that you must consider while making your buying decision. This list will help you to buy a Bluetooth OBD2 that suits your needs the best. 

OS Compatibility

Ideally, you should go for the OBD2 Bluetooth scanner that supports all the major operating systems such as macOS, Windows, Android, and iOS. However, if you can find or are on a budget and can’t afford one, then choose the product that’s compatible with the operating system you use. For example, if you have an iPhone and intend to use the scan tool or application on your smartphone then consider buying a Bluetooth OBD2 that’s compatible with iOS. It’ll keep you from spending money and time on buying or downloading a special operating system to use your Bluetooth OBD scanner.

App Compatibility

As we have already mentioned, most Bluetooth OBD2 adapters are designed to work with almost all the common scan tool apps. However, there are devices available in the market that require you to use a specific scan tool developed by the manufacturer. We recommend you buy a Bluetooth OBD2 adapter that’s compatible with the app you intend to use. 

Powerful OBD2 software with all the needed functionalities is yet another important factor that you need to consider in the scan tool app. You don’t want to use an app that offers limited or faulty operations. The scan tool must be dependable that you can easily download from the major app platforms such as Google Play Store and Apple’s App Store. 

Affordability

Easy to Set Up

A Bluetooth OBD2 scanner that you choose should be easy to set up. You don’t want to go into the hassle of solving compatibility or other issues. Consider buying a product that’s compatible with an easy to install app with a user-friendly interface. Moreover, the Bluetooth pairing function should also be seamless. It’s important to consider these features before buying an OBD2 Bluetooth adapter.

Emission Inspection

A standard Bluetooth OBD2 adapter should also offer functionality to perform smog tests and emission inspections.
