OBD Auto Doctor supports all ELM327 based hardware interfaces. Some of the adapters are listed in this page but many are left out. The best adapters in the market are from PLX Devices (Kiwi adapters) and ScanTool.net (OBDLink adapters). Those adapters have the best performance and compatibility with vehicles, and they are manufactured with high standards.


We recommend that you get a high quality adapter and suggest that you forget the cheap chinese OBDII clone adapters. If you are on budget, look for an older model of one of the premium models. You might find good deal on a genuine adapter.


In any case we do not recommend the clone OBD2 adapters. Some of them might work but some will not. The advertising on some of these adapters is incorrect and they might not work on the advertised cars. Moreover, getting a similar looking device doesn't guarantee similar behaviour. The clone manufacturers put different electronics in the same looking housing. At least be prepared to return a faulty unit back to the seller. Remember to check for the refund policy before purchasing one.

Bluetooth Low Energy (BLE) Adapters

Bluetooth Low Energy (BLE) adapters are the newest type of OBD2 adapters in the market. We predict that these adapters will become the most popular type once the BLE is adapted by more phones and computers. Bluetooth Low Energy is also known as Bluetooth Smart and Bluetooth 4.0.


Bluetooth Low Energy adapters work with all mobile platforms including Apple devices. However, each adapter model needs specific support from the software. It means that any generic BLE adapter will not work with OBD Auto Doctor automatically. We need to tailor the software and add special support for each adapter separately.


Please note that your device needs to have Bluetooth 4.0 in order to use these dongles. If you are looking for the traditional Bluetooth adapters, check the next section.
