WindowsCE固件支持多个蓝牙连接吗？
一台WindowsCE设备可以连接多个蓝牙设备吗？该设备需要既充当手机的蓝牙免提扬声器，又需要通过串行蓝牙连接连接到第三个设备。
应用程序可以在不需要特殊驱动程序的情况下执行此操作吗？
Can a WindowsCE device connect so more than one BlueTooth device? The device needs to both serve as a BlueTooth hands-free speaker for a phone and connect to a third device via a serial BlueTooth connection.
Can an application do this without the need of a speciel driver?

您必须了解 Windows CE 是一个模块化操作系统，任何特定平台功能均由 OEM 实现。 OEM 可以创建完全不支持蓝牙的 Windows CE 设备，或者他们可能选择仅实现蓝牙客户端配置文件（例如蓝牙音频设备），或者他们可能选择实现蓝牙服务器，以便可以使用蓝牙串行设备。他们也可能选择两者都实施。除了 OEM 在软件中所做的事情之外，硬件本身可能只允许其中之一（或者两者都允许，或者两者都不允许）。
缺点是我们无法真正回答您的问题，因为没有适合所有设备的通用答案。您必须询问设备 OEM 他们支持什么，以及如果他们不支持您需要的内容，他们是否可以扩展该支持。
You must understand that Windows CE is a modular OS and any specific platform capabilities are implemented by an OEM. An OEM can create a Windows CE device with absolutely no Bluetooth support or they might choose to implement just a Bluetooth client profile (say as a bluetooth audio device) or they may choose to implement a Bluetooth server so they can consume a Bluetooth serial device. They may also choose to implement both. Beyond what the OEM does in software, the hardware itself might allow only one or the other (or both or neither for that matter).
The short of this is that we can't actually answer your question becasue there is no generic answer that fits all devices. You have to ask the Device OEM what they support and if they can extend that support if they don't support what you need.
