As it stands in iOS 6.1.4, the current limit for Bluetooth Low Energy devices is 10 simultaneous CONNECTIONS (at least on the NRF8002 chipset). Although the BLE spec says it can in theory have an infinite number of connections, the connection will time out when you try to add an 11th device.
在 iOS 6.1.4 中，低功耗蓝牙设备的当前限制是 10 个同时连接（至少在 NRF8002 芯片组上）。尽管 BLE 规范说它理论上可以有无限数量的连接，但是当您尝试添加第 11 个设备时，连接将超时。
As for the pairing table, I've previously had two additional a2dp devices in my pairing table(not connected) and 10 current BLE connections as the maximum. So that is a total of 12 devices in the pairing table on an iPhone 5 running iOS 6.1.4. You could probably have more devices listed in the pairing table, but the one definite is 10 connections is the current max.
至于配对表，我之前在配对表中有两个额外的 a2dp 设备（未连接），当前最多有 10 个 BLE 连接。因此，在运行 iOS 6.1.4 的 iPhone 5 上，配对表中共有 12 台设备。您可能会在配对表中列出更多设备，但可以确定的是 10 个连接是当前的最大值。

The bluetooth specification allows more than one device to connect at a time, but it's not straightforward, as it is dependent on the type of device and the service profile it provides.
For example, you can have a bluetooth keyboard, mouse, and headset connected at the same time, and an A2DP (Advanced Audio Distribution Profile) device to stream music, but you can't have two devices that performing the same service profile connected at the same time.
蓝牙规范允许一次连接多个设备，但这并不简单，因为它取决于设备的类型和它提供的服务配置文件。
例如，您可以同时连接一个蓝牙键盘、鼠标和耳机，以及一个 A2DP（高级音频分发配置文件）设备来传输音乐，但是您不能同时连接两个执行相同服务配置文件的设备同时。
