Return the higher layer response bytes for Android.Nfc.Tech.NfcB tags.
Does not cause any RF activity and does not block.
The higher layer response bytes can be used to help identify a tag. They are present only on Android.Nfc.Tech.IsoDep tags that are based on Android.Nfc.Tech.NfcB RF technology. If this tag is not Android.Nfc.Tech.NfcB then null is returned.
In ISO 14443-4 terminology, the higher layer bytes are a subset of the ATTRIB response.
