NFC SNEP推送碎片-ACR122U到Android ICS P2P [英] NFC SNEP Push Fragmentation - ACR122U to Android ICS P2P

问题描述

如何完成?该文档尚不清楚，没有示例.

How is it done? The documentation is unclear and there are no examples.

我的工作如下.

我将数据切成小片段，然后按顺序发送这些片段. SNEP标头仅在第一个片段中包含一次.我是否需要更改SNEP标头或LLCP中的内容?我不明白应如何更改LLCP，以使android了解消息的顺序?发送完整个消息后，Android不会确认收到消息.

I chop off the data into small fragments and then I send the fragments sequentially. The SNEP header is only included once in the first fragment. Do I need to change something in my SNEP header or LLCP? I don't understand how LLCP should be changed to make android understand the sequence of the messages? After the whole message is sent, android does not acknowledge receiving the message.

示例将不胜感激.

C#桌面应用程序尝试通过NFC对等将数据发送到在SIII上运行的android ICS.非接触式智能卡读取器是ACS ACR-122U/T

C# Desktop application trying to send data through NFC Peer-to-Peer to an android ICS running on an SIII. The contact-less smart card reader is an ACS ACR-122U/T

推荐答案

SNEP碎片需要实现. LLCP序列号需要照顾，最后，我认为片段之间应该有一些确认消息，这就是我要去的地方.

SNEP Fragmentation needs to be implemented. LLCP Sequences numbers need to be taken care of and finally, I think there should be some acknowledgement messages in between fragments which is where I'm going wrong.
