我们有多少个最大的设备可以通过蓝牙配对到Android设备的时间？ [英] How many maximum device can we pair via Bluetooth to android device at a time?

问题描述

谁能告诉我有多少最大的设备才能通过蓝牙配对Android设备在同一时间.....我用Google搜索每一个地方，但我没有得到正确的答案。

Can anyone tell me how many maximum devices can we pair via Bluetooth to android devices at a time.....i googled every where but i didn't get the right answer.

推荐答案

在蓝牙微微网中一个主最多可以传达给7活跃的奴隶，可以有一些其他的多达248个设备这是在睡眠模式（可参加通信积极当另一个有源器件进入休眠模式）。

In a Bluetooth piconet one master can communicate up to 7 active slaves, there can be some other up to 248 devices which are in sleep mode (may participate to communication actively when another active device goes into sleep mode).

在装置的蓝牙scatternets（互连微网）数量没有限制。有些奴隶作为桥梁参与两个或多个微微网。其中一个蓝牙scatternets定义的最先进的拓扑结构是立方体连接环结构。

In Bluetooth scatternets (interconnected piconets) number of devices are not limited. Some slaves used as a bridge by participating two or more piconets. One of the most advanced topology defined for Bluetooth scatternets is Cube Connected Cycles architecture.

您可以设置多个蓝牙连接（至少RFCOMM连接）。只需使用其他线程的给你连接，它会正常工作（我猜）参见：的 http://developer.android.com/resources/samples/BluetoothChat/index.html

you can set up multiple bluetooth connections (at least RFCOMM connections). Just use a alternative thread for you connection, and it would work fine (I guess) See also: http://developer.android.com/resources/samples/BluetoothChat/index.html

这样的事情，

Method m = device.getClass().getMethod("createRfcommSocket", new Class[] {int.class});
tmp = (BluetoothSocket) m.invoke(device, 1);
