What is an OBD2 Bluetooth Adapter and What is It Used for?

An OBD2 Bluetooth adapter is a device that works to scan your vehicle’s engine. There is a thorough analysis of all the things, and then the screen displays the issues. There is an ELM327 micro-controller in OBD2 Bluetooth adapters, which creates an interface with your computer. 

The Bluetooth adapters have devices that establish Bluetooth connections with all your devices. Bluetooth radios, however, will not work with iOS devices, but you can use an OBD2 Wi-Fi adapter for them. 

Remember that the Bluetooth adapters will not scan your car on their own. Rather, they will just connect your devices with OBD2 scanners for a better and quicker display. 

Are All OBD2 Bluetooth Adapters The Same?

The basic purpose of all OBD2 Bluetooth adapters is to scan your vehicle’s engine. Still, all of them are not the same. They come with different features and different ways of displaying the results to you. Here is what distinguishes one OBD2 Bluetooth adapter from another. 

Data Processing Speed

The data processing speed of all OBD2 Bluetooth adapters is different from each other. There are varying degrees of speed and efficiency, which depend on the sensitivity of sensors. If the Bluetooth adapter works quickly, it will give you real-time results. There will be no delays in reports as well, so speedier adapters get preference over all others.

Device Compatibility

Not all OBD2 Bluetooth adapters are compatible with all devices, and this differentiates them as well. Most of the OBD2 Bluetooth adapters have high compatibility with Android devices. Windows and other operating systems work with these Bluetooth adapters as well. However, not all adapters are compatible with iOS devices, so you need to check that actively. 

Application or Software

Now, it is quite obvious that all manufacturers bring in their own software and mobile applications with their Bluetooth adapters. So, the efficiency and types of software also differentiate OBD2 Bluetooth scanners. 

What to Look for When Buying an OBD2 Bluetooth Adapter

Buying an OBD2 Bluetooth adapter is going to make your driving experience a lot better. But this depends on the kind of adapter that you are getting. So, keep the following aspects in mind while you decide to buy a new one for your vehicle. 


The whole point of having a Bluetooth adapter is to have a device that makes it easy to assess your vehicle. This is why the adapter should be portable enough for you to carry easily on your travels too. Thus, get a compact and sleek adapter so that it has high portability.


The display of OBD2 Bluetooth scanners is an important feature, as well. The display should be clear enough for you to see things on the go. The Diagnostic Test Codes (DTC’s) will appear on the screen to indicate any problems in the engine. But if the description of codes and reports of different sensors shows in an easy to read manner, then there will be greater ease of use. 


The Bluetooth range of an OBD2 Bluetooth adapter is significant too. The range should be broad enough for you to check your engine even when you are not sitting in the driver’s seat. This will make things easier for you, so you should consider the range of Bluetooth while making a decision.
