蓝牙并发连接 [英] Bluetooth concurrent connections

问题描述

有关在我的大学一个巨星，我们正在规划一个知识竞赛。

蜂鸣器轮，我想写2应用程式Android（我们有一些手机），一个用于测验主，另一个参赛者

参赛者将通过蓝牙连接到主测验

For a fest at my college, we are planning a quiz contest.
For the buzzer round, I was thinking of writing 2 app for android (we have a few handsets), one for the quiz master and the other for the contestants
The contestants will be connected to the quiz master through bluetooth.

阅读问题后，竞猜大师点击在他/她的应用按钮，在选手的应用按钮X秒启用。只要选手点击他/她的按钮，测验主人的应用程序会闪烁的选手的名字。

After reading the question, the quiz-master clicks a button in his/her app, the button in the contestant apps will be enabled for X seconds. As soon as a contestant clicks his/her button, the quiz master's app will flash the name of that contestant.

我的问题：

它甚至有可能有多个连接和蓝牙接受他们的并发（或复用）消息（）在UNIX / C相似，选择一些东西（）？

Is it even possible to have multiple connections and accept concurrent (or multiplexed) messages from them in bluetooth (something similar to select() in unix/c)?

如果可能的话，我应该在哪里寻找任何的例子吗？什么样的问题，我会面对试图制定这种（我知道的可靠性是个问题在这里），以及如何避免呢？

If possible, where should I look for any examples? What kind of problems will I face trying to develop this (I know reliability is an issue here) and how to avoid them?

我已经在笔记本电脑前尝试这样做，失败了。但是，也许我给-起得很早。请帮助。

I had tried this on laptops before and failed. But maybe I gave-up very early. Please help.

编辑：

我放弃行动的项目（太多连接滴）。我保持的问题，虽然开放

I gave-up the project (too many connection drops). I'm keeping the question open though.

推荐答案

蓝牙支持微微网，其中一个（测验）主可最多的 7奴隶。

Bluetooth supports piconets, in which a single (quiz) master can communicate with up to 7 slaves.

因此​​，在蓝牙的水平，这应该是可行的。我是对事不对人的说，如果有可能采用Android的蓝牙API来实现：S，虽然

So, at the Bluetooth level, this should be doable. I'm not the person to say if it's possible to implement using Android's Bluetooth API:s, though.
