Some Bluetooth OBD2 adapters are compatible with Android and Windows, but not iOS devices such as iPhone, iPad, iPod. However, most WiFi adapters are compatible with Android, iOS, and Windows. So, are WiFi adapters are better than Bluetooth adapters? Why do many high-end adapters use Bluetooth?

Apple MFi program

Many Bluetooth adapters are not compatible with iOS because of Apple MFi program. MFi stands for Made For iPod or Made For iPhone/iPod/iPad. Developers who wish to develop electronic accessories for iOS devices should join the MFi Program. When it comes to Bluetooth accessories, they require an MFi chip inside them to communicate with iOS devices. Manufacturers of OBD2 adapters don’t bother joining the program and putting the chip into their products. That’s why many cheap Bluetooth adapters are not compatible with iOS devices.

Bluetooth and WiFi

WiFi adapters are compatible with both Android and iOS. Then why are there Bluetooth adapters on the market? Both WiFi and Bluetooth provide wireless communication. But, WiFi is designed to provide high-speed access to the internet while Bluetooth is designed to connect two different devices wirelessly such as audio player and headphone or computer and printer. These characteristics reflect on the behavior of smartphones. When a smartphone has a secure WiFi connection, it stops using the data connection for internet. The problem is that OBD2 adapters are not internet modems. As a result, when you use a WiFi adapter, there is no internet connection on a smartphone. Thus, Bluetooth is more suitable for an OBD2 adapter than WiFi.

WiFi adapter with Android

Without an internet connection, you can’t search the details of OBD codes, look for a possible cause of the problems, or use a map feature of an app.  For iOS devices, to get around the issue of the loss of internet connection, you can change the setting of IP address to static to continue using internet from the data connection. Here is a WiFi setup guide for a DashCommand app. Please refer to each guide for other apps. With the setting done, you can use the internet while using an OBD2 adapter. However, it works on iOS devices only. Currently, Android devices can’t manage the setting of IP address. So, it’s important for Android users to choose a Bluetooth adapter to use full features of OBD apps.
