Are you experiencing trouble connecting your BAFX OBD2 scanner to your iPhone or iPad? It’s a common frustration for many car enthusiasts and DIY mechanics who rely on these tools for vehicle diagnostics. While OBD2 scanners like the BAFX Products 34t5 Bluetooth OBDII scan tool are designed to communicate with your car’s computer system, getting them to work seamlessly with iOS devices can sometimes be tricky. Let’s explore why your BAFX OBD2 scanner might not be working with your iOS device and how to troubleshoot common issues.
Understanding the iOS and Bluetooth OBD2 Scanner Compatibility Issue
Many users, like yourself, have found that while their OBD2 Bluetooth scanners connect effortlessly to Android devices, the same can’t be said for iPhones and iPads. You might go through the Bluetooth settings on your iOS device, search for new devices, but the OBD2 scanner simply doesn’t appear. This can be puzzling, especially when the scanner works perfectly with an Android phone.
The core of the issue often lies in Bluetooth protocols and Apple’s ecosystem. While OBD2 scanners like the ELM327 (which BAFX scanners often utilize compatible chips of) use Bluetooth for wireless communication, the way iOS devices handle Bluetooth connections, particularly with generic Bluetooth devices, can be restrictive.

Common Reasons for BAFX OBD2 and iOS Incompatibility
Several factors can contribute to your BAFX OBD2 scanner not working with your iOS device:
- Bluetooth Version and Compatibility: Older OBD2 scanners might use older Bluetooth versions that are not fully compatible with the latest iOS Bluetooth protocols. While generally backward compatible, issues can arise.
- Bluetooth Pairing Protocols: iOS devices are known for their stricter Bluetooth pairing requirements. Some generic Bluetooth OBD2 scanners might not adhere perfectly to Apple’s preferred pairing protocols.
- App Compatibility: The OBD2 app you are using on your iOS device plays a crucial role. Not all OBD2 apps are equally compatible with all OBD2 scanners and iOS versions. Ensure the app explicitly states compatibility with Bluetooth OBD2 scanners and iOS.
- Device Discovery Issues: Sometimes, the iOS device simply fails to discover the Bluetooth OBD2 scanner. This could be due to the scanner not being in pairing mode, Bluetooth interference, or limitations in iOS’s Bluetooth scanning capabilities for certain device types.
- MFi (Made for iPhone/iPad/iPod) Certification: Apple’s MFi program certifies external hardware to work optimally with iOS devices. Many budget-friendly OBD2 scanners, including some BAFX models, might not have this certification, which can sometimes lead to compatibility hiccups, especially with Bluetooth connections.
Troubleshooting Steps to Connect Your BAFX OBD2 Scanner to iOS
If you’re facing this issue, here are some troubleshooting steps to try:
- Verify Scanner and App Compatibility: Double-check the BAFX OBD2 scanner’s specifications and the OBD2 app description to ensure they are advertised as compatible with iOS devices and Bluetooth. Look for specific mentions of iOS versions supported.
- Bluetooth Pairing Mode: Ensure your OBD2 scanner is in pairing mode. Usually, this is indicated by a blinking light on the scanner itself. Refer to your BAFX scanner’s manual for specific instructions on entering pairing mode.
- Restart Bluetooth and Devices: Turn off Bluetooth on your iPhone/iPad, wait a few seconds, and turn it back on. Also, power cycle your OBD2 scanner by unplugging it from the OBD2 port and plugging it back in. Restart your iOS device as well.
- Try a Different OBD2 App: If you suspect the app might be the issue, try a different OBD2 app from the App Store that is known to be compatible with Bluetooth OBD2 scanners and iOS. Popular options include OBD Fusion, Car Scanner ELM OBD2, and others. Check app reviews for iOS compatibility feedback.
- Check for Firmware Updates (if applicable): Some higher-end OBD2 scanners have firmware update capabilities. Check the manufacturer’s website (BAFX Products in this case, if they offer firmware updates) to see if there are any updates available for your scanner that might improve iOS compatibility.
- Test on an Android Device (if possible): If you have access to an Android device, try connecting your BAFX OBD2 scanner to it. If it connects successfully to Android but not iOS, this further points towards an iOS-specific compatibility issue.
- Consider a WiFi OBD2 Scanner: If Bluetooth connectivity consistently fails with iOS, consider using a WiFi OBD2 scanner instead. WiFi OBD2 scanners often bypass some of the Bluetooth pairing complexities and can offer more reliable connections with iOS devices.

Conclusion
While BAFX OBD2 scanners are valuable tools for vehicle diagnostics, compatibility issues with iOS devices, particularly via Bluetooth, are not uncommon. By understanding the potential reasons for these issues and systematically troubleshooting, you can often find a solution. If Bluetooth connection remains problematic, exploring WiFi OBD2 scanner options might provide a more reliable pathway to connect your iOS device to your car’s diagnostic system. Remember to always prioritize using reputable OBD2 apps and verifying compatibility to ensure a smooth diagnostic experience.
