只能发送使用ISMB Java库/收到的消息一度 [英] Can only send / recieve message once using ISMB Java library
本文介绍了只能发送使用ISMB Java库/收到的消息一度的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用 HTTPS：//$c$c.google。 COM / p / ISMB-SNEP-的Java /
我有一个问题，我只能发送或接收一次消息。
I have a problem that I can only send or receive a message once.
我可以发送消息到手机上，然后我必须拔下读卡器
然后重新插上，然后我可以重复这一过程（发送/接收）。
I can send a message to the phone, and then I have to unplug the reader and then plug it again, and then I can repeat the process (send / receive).
我觉得有一些东西正在对阅读器进行设定，而不是被取消设置。
如果我重复这个过程，没有拔下它并重新插入它时，会出现以下错误：
If I repeat the process without unplugging it and replugging it, the following error occurs:

推荐答案
我有同样的问题与银河S4（5.0.1）。
I have same problem with Galaxy S4(5.0.1).
我试图用老项目与NDEF协议（ https：//开头code.google.com / p / ISMB-NPP-的Java / ）
I tried to use old project with NDEF protocol ( https://code.google.com/p/ismb-npp-java/ )
它工作正常。
这篇关于只能发送使用ISMB Java库/收到的消息一度的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
