相关的this问题，但......有没有可能通过API新的硬件设备扫描触发？我有我自动通过与 32feet.net .NET蓝牙 API调用配对的串行端口蓝牙设备，它的工作原理相当不错。虽然我可以在设备的扫描序列服务查询，COM端口不要在蓝牙设备对话框的COM端口选项卡中显示出来。

Related to this question, but... is it possible to trigger via API a new hardware device scan? I have a serial port Bluetooth device that I'm pairing automatically via API calls with 32feet.net .NET Bluetooth, which works quite nicely. While i can query for the serial services in the scanning of the device, the COM ports don't show up in the Bluetooth Devices dialog's COM Ports tab.
