Mobile versionIch habe vor dem pwd geschrieben und mit einem Lesegerät richtig gepackt.
Ich kann es mit dem Samsung Young 2, Android-Version 4.4.2 lesen.
Wenn ich versuche, sie mit einem Samsung Galaxy SIII Neo Android 4.4 zu lesen, habe ich eine Ausnahme mit dem gleichen Code, der den PWD-Befehl sendet und die Antwort liest.
Wenn ich einige Apps dazu verwende Lesen Sie diesen Tag, da TagInfo oder NFCTools mit Samsung Galaxy SIII Neo der Tag als ntag203 erkannt wird. Mit dem Samsung Young Galaxy 2 habe ich dieses Problem nicht, die App erkennt es ok.
Was passiert? Was ist los?
Ich habe es mit OnePlus One Mobile getestet und es funktioniert nicht. Ich habe auch eine Leseausnahme.
Hier ist die Ausnahmemeldung und der Stapel:
