WinRT BLE BluetoothLEDevice.GetGattServicesAsync 无法访问蓝牙 5

[英]WinRT BLE BluetoothLEDevice.GetGattServicesAsync unreachable Bluetooth 5

我有一个带有 Microsoft.Windows.SDK.Contracts V10.0.22621.2 的 .NET V4.72 应用程序来访问 WinRT 蓝牙低功耗 ZDB974238714CA8DE634A7CE1D083A1

它适用于 BLE 4.2 设备，但是当我尝试使其适用于 BLE 5.2 设备时，它无法正常工作。 我可以成功扫描并与 BLE 5.2 设备配对，但是当我尝试通过未缓存的 BluetoothLEDevice.GetGattServicesAsync 方法建立连接时，总是出现无法访问的错误。

我还尝试使用提供的示例 UWP ble 示例，但没有成功 - 行为完全相同。

这是什么原因造成的？
