我有一个NFC设备（ SCL3711 ）和 Google Nexus S 手机。我写了一个应用程序，它将数据从手机发送到NFC设备，反之亦然。在 Android 2.3.3 上，一切都运行良好。现在我将我的Nexus S操作系统更新为 4.0.3 Ice Cream Sandwich ，一切都停止了。现在我无法将数据从手机发送到NFC设备，反之亦然。我可以理解的主要原因是我无法连接到设备，但为什么我无法理解。
请帮助我，提供一些链接或信息来考虑这个问题。一切都对我有所帮助。

我在找到解决方案后关闭了这个问题，主要原因是协议更改而不是 ndef 现在我们必须使用 snep 协议。如果您有相同的问题更改协议类型。
