如何断开Windows 8.1上的蓝牙LE设备

Question

I'm developing an application with bluetooth low energy under Windows 8.1 and working with microsoft bluetooth le stack. I almost finish with all routines, I implemented: connection, reconnection, detection connection/disconnection notifications, connection state check... but one thing left - disconnection.

So, how to disconnect connected device using C++?

Answer 1

你不能，他们没有在windows sdk中实现这个功能，说维持连接比重新连接更好（在功耗方面）。

Answer 2

1. Remove all ValueChanged events (-=)
2. Set all GattCharacteristic to null
3. Call Dispose on all Gatt Devices Services
4. Call dispose on the BluetoothLEDevice
5. Set the BluetoothLEDevice member to null
6. GC.Collect()
7. GC.WaitForPendingFinalizers()
