Here you can find the list of scanFailedCodes: https://developer.android.com/reference/android/bluetooth/le/ScanCallback.html#SCAN_FAILED_ALREADY_STARTED

In your case, code 2 means SCAN_FAILED_APPLICATION_REGISTRATION_FAILED. Googling for it, shows a wide variety of reasons why this could happen. Please have a look. If you can't find the reason, we need to see your code.
