Choosing the right OBD2 scanner can be confusing. This article compares Bluetooth and WiFi OBD2 scanners, outlining their pros and cons to help you make an informed decision.
Connectivity: Bluetooth vs. WiFi
Bluetooth OBD2 scanners connect directly to your smartphone or tablet via Bluetooth. This creates a personal area network (PAN), offering a convenient and generally stable connection. However, Bluetooth’s range is limited, typically within 30 feet, and can be susceptible to interference from other Bluetooth devices. Some users, particularly iPhone users, have reported compatibility issues with Bluetooth OBD2 scanners.
WiFi OBD2 scanners, on the other hand, create their own WiFi network that your smart device connects to. This often provides a more reliable connection and extended range compared to Bluetooth. However, switching between your regular WiFi network and the scanner’s WiFi can be slightly less convenient. WiFi OBD2 scanners generally offer better compatibility with iPhones.
Software and Functionality
Both Bluetooth and WiFi OBD2 scanners work with various apps available on Android and iOS. Basic ELM327 based scanners offer code reading capabilities, allowing you to identify and clear diagnostic trouble codes (DTCs).

More advanced scanners, such as BlueDriver and OBDLink MX+, offer additional features like live data monitoring, enhanced code descriptions, and potential repair recommendations.
BlueDriver, for instance, provides detailed repair reports based on specific error codes and vehicle information, even without the BlueDriver scanner itself if you manually input the code and vehicle information. OBDLink MX+ excels in data monitoring and offers free access to enhanced code scanning for manufacturer-specific codes.
Cost Considerations
Basic ELM327 Bluetooth and WiFi OBD2 scanners are generally inexpensive, often under $20. However, they typically lack advanced features and rely on third-party apps for functionality. Premium scanners like BlueDriver and OBDLink MX+ are closer to the $100 mark but offer comprehensive features, ongoing support, and regular updates.
Conclusion: Making the Right Choice
Ultimately, the best choice between a Bluetooth and WiFi OBD2 scanner depends on your individual needs and budget. If you need a basic code reader and have an Android device, a Bluetooth scanner might suffice. If you require more advanced features, enhanced compatibility with iPhones, or a more stable connection, a WiFi OBD2 scanner is likely the better option. For professional-grade diagnostics or extensive data monitoring, investing in a premium scanner like BlueDriver or OBDLink MX+ is worthwhile.
