蓝牙方面的知识，进着只要是有用的信息就有分
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xuyan87101@126.com
再次的谢谢了……

要结贴了，如果想看看上面的资料的话就快点看啊

结了贴我们也能再看啊。只是可惜了，一共就一个：http://www.j2megame.org/index.php/content/view/337/125.html

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

同意楼上
xuyan87101 2009-08-13
呵呵……现在没事做，了解了解……
xuyan87101 2009-08-12
呵呵……再来点就结贴了^资料啊呵呵……

你怎么又高蓝牙了,我都转行了
xuyan87101 2009-08-11
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……

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，~~~

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

楼上的各位辛苦了，谢谢啊O(∩_∩)O~

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。
http://www.j2megame.org/index.php/content/view/337/125.html
这个上面有一个实例
本来准备贴过来 太长了
[/Quote]
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……

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~
