How do I troubleshoot Bluetooth pairing issues with the RepairSolutions2 app?

If you cannot link with the RepairSolutions2 app, verify that Bluetooth is enabled on both your smartphone and the 5210 scanner. Update the app to the latest version and move closer to the scanner to reduce interference. If issues persist, check that your vehicle is OBD2 compliant and inspect the OBD2 port for damage.
