广播消息或文件到附近的蓝牙设备 [英] Broadcast message or file to nearby Bluetooth devices
问题描述
我们的客户端是参加商务公正，愿推动某种欢迎信息的人访问他们的空间。
A client of ours is attending a business fair and would like to push some sort of "welcome message" to people visiting their space.
我不是太熟悉，蓝牙，所以我有几个问题：
I'm not too familiar with Bluetooth, so I have a few questions:
- 您可以通过蓝牙传输什么样的内容？ （难道只有文件或是否有可能发送一个简单的短信？）
- 是否有可能在一定距离内将内容只有收件人？ （即基于信号强度或类似）
- 任何人可以推荐一个软件，可以做一些或所有上述？ 的
如果有必要，我们可以编写一个定制的解决方案我们自己（.NET），但我敢肯定，必须有一个程序，有可以做的工作。
If necessary we could program a custom solution ourselves (.NET), but I'm sure there must be a program out there that can do the job.
我GOOGLE了一下，整个
I've googled a bit and came across the 32feet.NET framework - does anybody have any experience with this framework?
在此先感谢您的任何建议！
Thanks in advance for any suggestions!
推荐答案
有几乎所有的设备都支持蓝牙配置文件（当然不是耳机！）呼吁OPP这是OBEX对象推送，它使用由红外定义的OBEX协议。它可以携带任何类型的文件，但接收设备可能不知道如何处理所有类型的... previously仅用于vCard支持是常见的（地址簿，任务/约会等）。
There's a Bluetooth profile supported by nearly all devices (well not headphones!) called OPP that's Obex Object Push, which uses the OBEX protocol as defined by the IrDA. It can carry any file type, but the receiving device may not know what to do with all types... Previously only support for vCards was common (address book, tasks/appointments, etc).
该32feet.NET库包括OBEX和蓝牙功能直接看到的用户指南。还有一个同伴库 Brecham.Obex ，提供更专业的支持OBEX 。我们支持内置微软和PC上了Widcomm蓝牙堆栈，但尚未BlueSoleil的[5]，但在安装MSFT堆栈是简单的。
The 32feet.NET library includes support for OBEX and Bluetooth directly, see the examples in the user guide. There's also a companion library Brecham.Obex that provides more specialised OBEX support. We support the built-in Microsoft and the Widcomm bluetooth stacks on the PC, but not yet BlueSoleil[5] but installing the MSFT stack is simple.

[5]：我做我自己的时间增加的Widcomm的支持，因为我现在没有工作我在寻找资金，增加对BlueSoleil的支持，我的大工作
