蓝牙方面的知识，进着只要是有用的信息就有分

[xuyan87101]

蓝牙方面的知识，只要是蓝牙方面的资料都可以，希望是自己做的程序源码分享一下，最近没事想研究一下这方面的知识，wtk上的例子就不要说了，我自己就可以看的O(∩_∩)O~，呵呵……谢谢大家了……

我希望各位兄弟姐妹们能给点实例，不要让我在网上搜索了，呵呵……我已经搜索了好些了……

就把实例发到我邮箱吧，嘿嘿……谢谢……

我的邮箱[e-mail]

再次的谢谢了……

[zl3450341]

实例代码

该程序包括3个java文件。一个是MIDlet,另外2个为服务端GUI和客户端GUI。该程序已经在wtk22模拟器和Nokia 6600,Nokia 6670两款手机上测试通过。

这个上面有一个实例
本来准备贴过来 太长了

[xuyan87101]

恩，知道，那个实例已经看过了，呵呵……谢谢啊……

有没有自己做的而且还是不错的？？？呵呵……比如蓝牙通讯蓝牙控制设备之类的程序？？？谢谢啊忽忽O(∩_∩)O~

期待中……

大家加油……O(∩_∩)O~

本来准备贴过来 太长了

和这位的一样的，呵呵……

有没有做好的两个可以相互通讯的蓝牙程序啊？？？
就是像发短信那样……

[xuyan87101]

楼上的各位辛苦了，谢谢啊O(∩_∩)O~

[doney_dongxiang]

我一般 使用蓝牙的时候 直接查看 API文档，也建议 楼主 查看API吧 顺便说一下，WTK下面的一些源代码 也有蓝牙功能的

[LeoTang2]

貌似一个实例，有手机屏幕与模拟器的对比图的一个案例：
------------------------------------------------------------------------------
引用 3 楼 foolstudio2 的回复:
到机械工业出版社下载《J2ME手机高级编程》一书的源代码，好像是5还是6章，
是在NOKIA 5310还是5320 的机器上进行蓝牙通信，可以参考下，免费注册之后就可以下载了。


从书上看的，在N5310上运行的状况似乎和WTK模拟器上是一模一样的，~~~
------------------------------------------------------------------------------

[xuyan87101]

这大早上的都去哪喝茶去了？？？没事了i来讨论一下吧，顶一下……

[chaner2002]

你怎么又高蓝牙了,我都转行了

[xuyan87101]

呵呵……再来点就结贴了^资料啊呵呵……

[xuyan87101]

呵呵……现在没事做，了解了解……

[javacaspnet]

同意楼上

[michaelscofielddong]

现在正在学习，楼主的帖子很不错，跟帖的代码太长了，看不懂

[xuyan87101]

要结贴了，如果想看看上面的资料的话就快点看啊
呵呵……发好几天了该结了……谢谢各位楼上的O(∩_∩)O~
